The present invention is directed to an information processing apparatus capable of easily inputting a telephone number. In a cellular phone equipped with jog dial 22, displayed on LCD display 18 of such cellular phone are the telephone number display section 71 and fixed cursor 72. Also displayed on the LCD display 18 are a substantially arc shaped line and digits at the periphery of such arc. When the jog dial 22 is manipulated upwardly, the digits displayed at the periphery of the arc are moved downwardly. Upon depressing the jog dial 22, the digit displayed in the cursor 72 is additionaly displayed in the telephone number display section 71. The present invention may be applied to cellular phones.
Reference is made to FIG. 1 to describe procedures of inputting a telephone number using a cellular phone equipped with a jog dial. A cellular phone 200 is provided with a display section 201 including a liquid crystal display at the upper section. Also provided with the cellular phone 200 is with a jog dial 202 on a side surface of the cellular phone 200 and at the left side of the display section 201. The display section 201 includes a number display section 211 for displaying digits 0 to 9 to input a telephone number, a cursor 212 movable onto one of these digits and a telephone number display section 213 for displaying the selected digits (a telephone number).
The jog dial  202 is normally designed to be turned in both up and down directions and can be depressed towards the main body of the cellular phone 200. In case of inputting a telephone number, the jog dial 202 is turned in up or down direction to move the cursor 212 on the digits displayed in the number display section 211. When the cursor 212 is on the number including the desired telephone number such number can be selected by depressing the jog dial 202 and the selected number is In addition displayed in the telephone number display section 213.
Although the telephone numbers are inputted in the above manner, it is to be noted that the jog dial  202 is manipulated in the up or down direction while the cursor 212 moves in left or right direction. Such different directions of manipulating the jog dial 202 and moving the cursor 212 cause problems such as consuming a longer time for inputting and selecting a wrong number because the user must select a desired number while paying attention to the fact that the up-down direction is converted into the left-right direction.
In addition, although a desired number is selected by moving the cursor  212 onto such number, the display section 201 of a cellular phone is so small that the displayed digits and the moving cursor 212 are not clear enough especially for weak-sighted users. Furthermore, since only the cursor 212 moves, i.e., the screen display lacks in dynamic changes, it is difficult for the user to quickly recognize if the result of his/her manipulation (operation) is displayed.
In the second information processing apparatus, method and recording medium according to the present invention, either a larger or a smaller number than the currently displayed number is displayed in response to the manipulation of the operation section in a first direction. The displayed number is displayed at a different display area if the operation section is manipulated in a second direction.
FIG. 20 shows a drawing for describing a medium.
Now, embodiments of the present invention will be described hereunder by reference to the accompanying drawings. FIG. 3 illustrates the construction of one embodiment of the information processing apparatus to which the present invention is applied. Illustrated in FIG. 3 is a network system in which portable information terminals  1-1 to 1-4 are connected. Base stations 2-1 to 2-4 which are fixed wireless stations are provided in each cell of desired size dividing the communication service area. Connected to the base stations 2-1 to 2-4 through a wireless communication network such as, e.g., W-CDMA (Wideband-Code Division Multiple Access) are the portable information terminals 1-1 to 1-4 which are mobile wireless stations. Large capacity high-speed data communication up to a maximum of 2 [Mbps] can be performed between them using a 2 [GHz] frequency bandwidth.
Since the portable information terminals  1-1 to 1-4 can perform large capacity, high speed data communication by the W-CDMA system, it is possible to communicate various data, not only voice communications but also transmitting and receiving electronic mails, reading simple home pages, transmitting and receiving images, etc.
Also, the base stations  2-1 to 2-4 are connected each through a wire to a public network 3 to which internet 5 and many subscriber terminals, computer networks and intranets (not shown) are connected. Also connected to the public network 3 is an access server 6 for an Internet service provider to which a contents data server 7 is connected.
The contents data server  7 provides contents data such as, e.g., simple home pages in a form of a file of, e.g., compact HTML (Hyper Text Markup Language) upon request by the subscriber wire terminals or the portable information terminals 1-1 to 1-4.
It is to be noted that, connected to Internet  5 are a large number of WWW servers 8-1 to 8-N for enabling the subscriber wire terminals and the personal information terminals 1-1 to 1-4 to gain access to the WWW servers 8-1 to 8-N in accordance with the TCP/IP (Transmission Control Protocol/Internet Protocol) protocol.
In practice, communication is made by the simple transport protocol in 2 [Mbps] between the portable information terminals  1-1 to 1-4 and the base stations (not shown) 2-1 to 2-4 while by the TCP/IP protocol between the base stations 2-1 to 2-4 and the WWW servers 8-1 to 8-N.
It is to be noted that an administrative controller  4 is connected to the subscriber terminals and the probable information terminals 1-1 to 1-4 through the public network 3 for performing authentication and charge processing to the subscriber wire terminals and the portable information terminals 1-1 to 1-4.
Now, the portable information terminals  1-3 and 1-4 will be described. The portable information terminals 1-1 and 1-2 are generally known as PDAs (Personal Digital Assistants) while the portable information terminals 1-3 and 1-4 are generally known as cellular phones.
Illustrated in FIG. 4 is an external view of the cellular phone such as the portable information terminal  1-3, 1-4. The portable terminal 1-3, 1-4 is a cellular phone provided with a camera capable of taking pictures and is referred to as a cellular phone 10 hereinafter. As illustrated in FIG. 4, the cellular phone 10 is divided into a display section 12 and a main body 13 by a central hinge section 11 so as to be folded at the hinge section 11.
The display section  12 includes an antenna 14, installed at the upper left section in such a manner to be pulled out or pushed in, for transmitting and receiving radio wave to and from the base station 2. The display section 12 is also provided with a camera section 15 at the center top section in such a manner to be turned at an angle of about 180 degrees. The camera section 15 includes a CCD (Charge Coupled Device) camera 16 capable of taking pictures of any desired object.
By positioning the camera section  15 by turning about 180 degrees by the user, the display section 12 is switched to a normal voice communication mode, wherein a speaker 17 at the back center of the camera section 15 faces the front as shown in FIG. 5.
In addition, the display section  12 is provided with a liquid crystal display 18 on the front surface for displaying not only the radio wave receiving condition, the remaining lifetime of the battery, names and telephone digits as registered in the telephone directory and communication histories but also images such as contents of electronic mails, simple home pages and pictures taken by the CCD camera 16 of the camera section 15.
On the other hand, the main body  13 includes on the surface various operation keys 19 such as numerical keys 0 to 9, a CALL key, a REDIAL key, an END/POWER key, a CLEAR key and Electronic mail key. Also, the main body 13 is provided with a MEMO button 20 and a microphone 21 below the operation keys 19; the MEMO button 20 is used to record voice communication with the interlocutor. The microphone 21 is used to pick-up user's voice.
Disposed on the left side surface of the display section  12 slightly extending outwardly from the display section 12 is a jog dial 22 to be used for various operations such as scrolling the telephone list or the Electronic mails displayed on the liquid crystal display 18, turning the page of simple home pages and transmitting images by turning the jog dial 22.
For example, the user can turn the jog dial  22 for selecting a desired telephone number from a plurality of telephone numbers in a telephone list displayed on the liquid crystal display 18. Upon depressing the jog dial 22 towards the inside of the display section 12, the selected telephone number is defined and an autodialing operation to the selected telephone number is initiated.
The main body  13 has a battery pack (not shown) installed in the back. If the hang up/power key is in the ON condition, power is supplied from the battery pack to each circuit section and the cellular phone becomes the operable condition.
It is to be noted that, the main body  13 is formed with a slot 23 in the upper side surface for inserting or extracting a memory stick (trademark of Sony Corporation) 30. When the MEMO button 20 is depressed, voice of the person one is speaking to is recorded in the memory stick 30 or electronic mails, simple home pages or pictures taken by the CCD camera 16 are recorded depending on the user's operation.
Since the cellular phone  10 is designed to allow insertion or extraction of the memory stick 30, the data can be shared with other electronic equipment by means of the memory stick 30.
As illustrated in FIG. 6, the cellular phone  10 includes a main control section 40 for supervising the control of the each section of the display section 12 and the main body 13. The main control section 40 is connected through a main bus 50 to a power supply circuit section 41, an operation input control section 42, a video encoder 43, a camera interface (I/F) section 44, a LCD control section 45, a video decoder 46, a multiplexing separation section 47, a recording/reproducing section 52, modulation/demodulation (MODEM) circuit section 48 and an audio codec 49. Also, the video encoder 43, the video decoder 46, the multiplexing separation section 48 and the audio codec 49 are connected to one another through a synchronization bus 51.
Upon user's operation of the hang up/power key, the power supply circuit section  41 is turned on and supplies power from the battery pack to each section so that the cellular phone 10 becomes the operable condition.
In accordance with the control of the main control section  40 including a CPU, a ROM and a RAM, the audio codec 49 of the cellular phone 10 converts the voice signal picked up by the microphone 21 in the voice communication mode into the digital audio data. Such audio data undergoes spread spectrum processing by the modulation/demodulation circuit section 48 and is transmitted from the antenna 14 after digital/analog conversion processing and frequency conversion processing by a transmitting/receiving circuit section 53.
Also, in the voice communication mode, the cellular phone  10 performs amplification, frequency conversion and analog/digital conversion on the signal received by the antenna 14. Such signal is, then, reverse spread spectrum processed by the modulation/demodulation circuit section 48 and converted into the analog sound signal by the audio codec 49 before being outputted from the speaker 17.
Furthermore, in case of transmitting electronic mails in the data communication mode of the cellular phone  10, the text data of electronic mail inputted by the operation keys 19 and the jog dial 22 is outputted to the main control section 40 through the operation input control section 42.
The main control section  40 performs the spread spectrum processing of the text data by the modulation/demodulation circuit section 48 as well as the digital/analog conversion processing and the frequency conversion processing by the transmitting/receiving circuit section 53 before being transmitted to the base station 2 (FIG. 3) through the antenna 14.
On the contrary, in case of receiving an electronic mail in the data communication mode of the cellular phone  10, the signal received from the base station 2 through the antenna 14 is reverse spread spectrum processed by the modulation/demodulation circuit section 48 to reproduce the original text data before displaying the electronic mail on the liquid crystal display 18 through the LCD control section 45. Then, the cellular phone 10 is capable of recording the received electronic mail in the memory stick 30 through the record reproduction section 52 in accordance with the user's operation.
On the other hand, in case of transmitting a video data in the data communication mode of the cellular phone  10, the image data taken by the CCD camera 16 is supplied to the video encoder 43 through the camera interface section 44.
It is to be noted that, in case of not transmitting the video data, the cellular phone  10 is also capable of directly displaying the image data taken by the CCD camera 16 on liquid crystal display 18 through the camera interface section 44 and the LCD control section 45.
The video encoder  43 converts the video data supplied from the CCD camera 16 into coded video data by compressed coding in accordance with a desired coding system such as MPEG (Moving Picture Experts Group) 2 and such converted data is sent to the multiplexing separation section 47. At this event, the cellular phone 10 sends the digital audio data of the sound picked up by the microphone 21 while taking pictures by the CCD camera 16 to the multiplexing separation section 47 through the audio codec 49.
The multiplexing separation section  47 multiplexes in the predetermined method the coded video data supplied from the video encoder 43 and the audio data supplied from the audio codec 49. The resulting multiplexed data is spread spectrum processed by the modulation/demodulation circuit section 48 and also performed digital/analog conversion processing and frequency conversion processing by the transmitting/receiving circuit section 53 before being transmitted through the antenna 14.
Conversely, in case of receiving moving video file data linked to, e.g., simple home page in the data communication mode of the cellular phone  10, the signal received from the base station 2 through the antenna 14 is performed the reverse spread spectrum processing by the modulation/demodulation circuit section 48 and the resulting multiplexed data is sent to the multiplexing separation section 47.
The multiplexing separation section  47 separates the multiplexed data into the coded video data and the audio data and the coded video data is then supplied to the video decoder 46 and the audio data is supplied to the audio codec 49 through the synchronized bus 51.
The decoder  46 decodes the coded video data to reproduce the moving video data in accordance with a decoding method corresponding to the predetermined coding method such as MPEG2 and such decoded video data is then supplied to the liquid crystal display 18 through the LCD control section 45, thereby displaying the moving video data contained in the moving video file linked to, e.g., the simple home page.
At this event, the audio codec  49 converts the audio data into the corresponding analog voice signal to be supplied to the speaker 17, thereby reproducing the audio data contained in the moving video file linked to, e.g., the simple home page.
Similar to the case of the electronic mail, the cellular phone  10 is capable of recording the data linked to the received simple home page in the memory stick 30 through the recording/reproducing section 52 in accordance with the user's operation.
In this sense, the cellular phone  10 has not only the function as a telephone but also the function of transmitting/receiving electronic mails and reading home pages. It is possible to select any one of such various functions. In case of searching home pages, it is essential for the cellular phone 10 having a small display area to provide easy-to-use graphic user interface.
Now, description will be made on the programs for the graphic user interface of the cellular phone  10. FIG. 6 is a diagram for describing the operation of the program to be used in the graphic user interface for controlling the menu displayed on the liquid crystal display 18. The program of the graphic user interface is stored in a ROM (not shown) in the main control section 40 for performing the processing to be described hereinafter by reading out the programs stored in such ROM.
A physical device  61 in FIG. 6 is, e.g., a memory area necessary for generating the video image on the liquid crystal display 18 in accordance with the application. A graphic device interface (GDI) 62 is a video component necessary to generate the above application video image. It is used to correlate the program necessary to generate on the liquid crystal display 18 images such as, e.g., cursor image, a scroll bar, a window frame and images supplied from the CCD camera 16 or logic devices and the memory areas storing such logic devices.
The logic devices are stored in a ROM (not shown), e.g., in the main control section  40 as a menu selection object data. The application images are formed as bit map data on the memory (the physical device 61) through the graphic interface 62 by specifying the relationship between the logic devices and their locations by the GUI and such bit map data is repeatedly read out to be displayed on the liquid crystal display 18, thereby producing the application images on the liquid crystal display 18.
External operators  63 are the operation keys 19 and the jog dial 22. In case of occurring any event such as turning the jog dial 22 for moving the image of the logical devices (e.g., cursor) displayed on the liquid crystal display 18 or continuously depressing the jog dial 22, since the addresses of the above mentioned memory area and pixels on the screen of the liquid crystal display 18 are correlated, a device handler (device driver) 64 detects the direction and amount of turning of the jog dial 22; the device handler 64 starts communicating with an interaction manager 65.
The interaction manager  65 interacts with an application program 66 based on the detected information. The application program 66 is developed in accordance with the intended use of the graphic user interface and is a program for defining the application images to be displayed on the liquid crystal display 18 and the detailed procedures to the input events from the external operators 63. Once the application 66 and the interaction manager 65 determine the response application image to the input event, the application 66 notifies the result to a display operation program 67.
The display operation program  67 operates to determine the way of displaying the response application images and, for example, the image that has been displayed before inputting any event is displayed as is and image elements of changed in location are distinguished by the operation. If new logic devices are required, such devices are read out of the memory locations and the GDI 62 is instructed to generate the response application image on the above mentioned memory.
According to the above construction, it is possible to implement the graphic interface with the operator on the liquid crystal display  18 in case of inputting the telephone number in response to the turning of the jog dial 22 as described hereinafter.
Next, the operation of inputting telephone digits provided by the graphic interface, as described hereinabove will be made by reference to the flowchart in FIG. 7. In step S 1, there occurs an event of turning the jog dial 22. As a premise, a telephone number input controlling program must be started prior to inputting such telephone number. It is to be noted that such program at the time of inputting telephone number may be started upon predetermined operations, e.g., turning of the jog dial 22, selection of icon menu, etc.
FIG. 8 illustrates one example of images on the LCD display  18 to be displayed upon starting the predetermined program when inputting telephone number. Displayed on the LCD display 18 is an arc (semi-ellipse) having a telephone number display section in the arc for displaying the inputted telephone number. The jog dial 22 is typically circular and one half of which is accommodated in the display section 12 of the cellular phone 10 (see FIG. 3) while the remaining half is extending outwardly to be visible to the user.
By taking advantage of such particular shape, it is preferable to provide a display on the LCD display so that the half of the jog dial  22 visible to the user and the arc displayed on the LCD display 18 form an image of a complete circle (of different magnification factor).
Displayed along the circumference of the arc on the LCD display  18 are digits 0 to 9. It is unnecessary to display all digits 0 to 9 at one time but as many digits as possible may be displayed. In the particular example in FIG. 8, digits 0 to 3 and 7 to 9, 7 digits in total are displayed. For example, in the display condition in FIG. 8, downward turning of the jog dial will result in the display screen as shown in FIG. 9.
In other words, the downwards turning of the jog dial  22 will give an impression to drag the dial, thereby causing the digit “7” to disappear from the LCD display 18 and replaced by the digit “8” and shifting the display locations such as displaying the digit “9” at the location of “8”, etc. As a result, 7 digits in total including digits 0 to 4 and 8-9 are displayed on the LCD display 18.
On the other hand, if the jog dial  22 is turned upwardly from the display condition in FIG. 8, the display will be shifted to give an impression of dragging the dial to cause the digit “3” to disappear from the LCD display 18 and shifting the display locations of the remaining digits by 1 in such a manner to display “6” at the location of “7”.
As described hereinabove, the display locations of the digits on the LCD display  18 advance in ganged with the turning of the jog dial 22 so as to display a new digit not displayed previously.
Displayed on the LCD display  18 is a fixed cursor 72 in which a digit is displayed in magnified than other digits. The cursor 72 may be at any location but it is preferable to choose the most visible location. The user operates the jog dial 22 so that the intended digit including the telephone number will be displayed in the cursor 72.
In addition, upon depressing the jog dial  22 when, e.g., “0” is displayed in the cursor 72 (as shown in the example in FIG. 8), such digit “0” is displayed in the telephone number display section 71 as shown in FIG. 10. The user repeats the above operations for sequentially inputting digits including the intended telephone number.
Returning to the flowchart in FIG. 7, after occurrence of the jog dial turning event in step S 1, the procedures advance to step S2 in which a selected digit corresponding to the turning event is displayed in the cursor 72. In step S3, upon occurrence of depressing event of the jog dial 22, the procedures advance to step S4 in which selected digits are sequentially inserted and displayed in the telephone number display section 71.
In step S 5, a judgment is made whether or not any send button (one of the operation keys 19 in FIG. 3) has been depressed. In other words, if inputting of the telephone number is not finished, the procedures return to step S1 and similar procedures as mentioned above are repeated. On the other hand, if it is determined in step S5 that the complete telephone number has been inputted, the procedure advances to step S6 in which connection is initiated to the telephone number as specified in the telephone number display section 71.
In this sense, by making the direction of manipulation of the jog dial  22 match the direction of movement of the digits displayed on the LCD display 18, it is possible for the user to intuitively recognize the number to be selected, thereby avoiding any error in selecting the digits. Also, moving the digits with respect to the fixed cursor makes the image dynamic and the digits easy to select.
Next, before describing another embodiment of inputting a telephone number by reference to the flowchart in FIG. 11, a reference will be made to FIG. 12 for describing images on the LCD display  18. As shown in FIG. 12A, a telephone number display section 81 for displaying the telephone number including the inputted digits is located at the upper side of the LCD display 18. There is provided a number display section 82 for displaying a single digit below the telephone number display section 81.
When the jog dial  22 is depressed in the display condition as shown in FIG. 12A, a digit, i.e., “0” is additionally displayed on the telephone number display section 81. As a basic operation, the user manipulates the jog dial 22 so that the desired number including the telephone number is displayed in the number display section 82 and then, by depressing the jog dial 22, the above operations are sequentially repeated for storing the number including the telephone number.
Describing the flowchart in FIG. 11, upon occurrence of the turning event of the jog dial  22 in step S11, it is checked if the turning direction is upwards, in step S12. If it is determined that the turning direction is upwards, the procedures advance to step S13 in which the displayed digit is magnified in a predetermined step. Such magnified display will be described herein after by reference to FIG. 13.
When the jog dial  22 is turned upwardly while, e.g., “0” is displayed in the number display section 82 (as shown, e.g., in is FIG. 12B), the magnified display is the digit “1” which is the larger digit next to “0”. In other words, the digit “1” is first displayed relatively small in the number display section 82 as shown in FIG. 13A. Then, it is displayed as shown in FIG. 13B in a larger size than in FIG. 13A. Subsequently, it is displayed as shown in FIG. 13C in larger size than in FIG. 13B. In this manner, the displayed number will be magnified in steps.
While such magnified display is being performed in step S 13, in a case when the direction of turning of the jog dial 22 is determined to be downwards rather than upwards in step S12, the procedures advance to step S14 for performing a reduced number display. The reduced display is opposite to the magnified display. In other words, in the display condition of, e.g., FIG. 13C, if the jog dial 22 is turned downwards, “0” which is smaller digit next to “1” is displayed in reduced size as shown in FIG. 14.
First, a large “0” is displayed in the number display section  82 as shown in FIG. 14A. It is, then, displayed as shown in FIG. 14B in a smaller size than in FIG. 14A and, as shown in FIG. 14C, it is displayed in even smaller size than in FIG. 14B.
The number is displayed on the LCD display  18 while performing the magnified display in step S13 or the reduced display in step S14. If the displayed number is one of the digits including the telephone number that the user is going to call, the jog dial 22 is depressed. Upon occurrence of the depression event of the jog dial 22 in step S15, the procedures advance to step S16 in which the sequential number is additionally displayed in the telephone number display section 81. In step S17, judgment is made whether the send button (not shown) is operated and, if it is determined that it has been operated, the procedures advance to step S18 in which connection is initiated; on the other hand, if it is determined that the send button has not been operated, the procedures return to step S11 to repeat the subsequent procedures.
As described hereinabove, only the number is displayed without displaying the cursor or the like, thereby enabling a weak-sighted user to easily recognize the number and avoiding possibility of selecting a wrong number. If the number displayed in magnified or reduced size is selected and In addition registered in the telephone number display section  81, it is also possible to have a condition of erasing the number and displaying nothing in the number display section 82 until subsequent manipulation of the jog dial 22.
Next, still another way of inputting a telephone number will be described. Shown in FIG. 15 are examples of images on the LCD display  18 in another embodiment. The example in FIG. 15A has basically the same screen configuration as in FIG. 12 including a telephone number display section 91 and a number display section 92. However, in the embodiment as shown in FIG. 15A, a plurality of digits (5 digits from 2 to 6 in FIG. 15A) are displayed in the number display section 92. Also displayed is a fixed cursor 93 for displaying the central number therein.
The number to be displayed in the cursor  93 is larger in size than the other digits and, in a model in which color display is available, it is preferable to display the central number in a color different from the other digits.
In a case in which a desired number including the telephone number is displayed in the cursor  93, the user depresses the jog dial 22. Upon depressing the jog dial 22, the number displayed in the cursor 93 is displayed in the telephone number display section 91 as shown in FIG. 15B. Such procedures of selecting 20 digits by turning the jog dial 22 and deciding digits by depressing the jog dial 22 are repeated for inputting any desired telephone number.
If the direction of turning of the jog dial  22 is determined upwards in step S22, the procedures advance to step S23 in which digits displayed in the number display section 92 are shifted to the left. If the jog dial 22 is turned upwards in the display condition, e.g., as shown in FIG. 13, the numbers displayed in the number display section 92 are sequentially shifted to the left as shown in FIG. 17.
In other words, the number “2” displayed in the number display section  92 is pulled out as a result of the upwards turning of the jog dial 22. In other words, it gives an image that “2” is dragged out and the other numbers are shifted to the left in accordance with the dragging. As a result, also displayed in the number display section 92 is the number “7” which has not been previously displayed.
On the other hand, if the direction of turning the jog dial  22 is determined to be downwards rather than upwards in step S22, the procedures advance to step S24 in which the numbers displayed in the number display section 92 are shifted to the right. In other words, as shown in FIG. 17B, the number “7” displayed at the right end is pushed out by the downwards turning of the jog dial 22. As a result, other displayed numbers are sequentially shifted to the right and newly displaying the number “1” at the left end.
As described hereinabove, the user turns the jog dial  22 so that the desired number is displayed in the cursor 93. The procedures in step S25 and the subsequent steps are the similar to the step S15 and the subsequent steps in FIG. 11 and thus description will be omitted herein.
It is to be noted that although the numbers displayed in the number display section  92 are shifted to the left when the direction of turning of the jog dial 22 is upwards in the above description, they may be shifted to the right and, similarly, shifting the numbers displayed in the number display section 92 to the right by the downwards turning of the jog dial 22 in the above description may be modified to shift to the left.
In other words, in the configuration as shown in FIG. 15, since the visible bottom end of the jog dial  22 corresponds to the line of arranged numbers in the number display section 92, upwards turning of the jog dial 22 gives an impression to the user that the numbers displayed in the number display section 92 are pulled out, it is preferable to shift them to the left. However, if the upper end of the visible jog dial 22 is made to correspond to the line of arranged numbers in the number display section 92, it is preferable to shift the numbers to the right, thereby giving an impression to push them out when the jog dial 22 is turned upwardly.
As described hereinabove, it is preferable to set the direction of shifting the numbers displayed in the number display section  92 either to the right or the left depending on the direction of turning of the jog dial 22 as well as the location of the jog dial 22 installed in the cellular phone 10.
Such arrangement to give an impression to the user that the direction of turning of the jog dial  22 coincides with the direction of shifting the numbers displayed in the number display section 92 enables the users to easily and instinctively manipulate to display the desired number in the cursor 93. In addition, moving the numbers with respect to the fixed cursor 93 is effective to actively moving the images in the number display section 93, thereby enabling weak-sighted users to easily recognize the changes in the display.
Yet another embodiment of inputting a telephone number will be described by reference to the flowchart in FIG. 18. Since the processing steps in the flowchart in FIG. 18 are basically the same as those in FIG. 11, no detailed descriptions will be given but only differences will be described hereinafter. If it is determined that the direction of turning of the jog dial  22 is upwards in step S32, the procedures advance to step S33.
In step S 33, a display will be performed to give an impression to the user that the number to be displayed on the LCD display 18 is turning backwardly. On the other hand, if the direction of turning of the jog dial 22 is determined to be downwards rather than upwards in step S32, the procedures advance to step S34. In step S33, performed is a display to give an impression that the number displayed on the LCD display 18 turns forwardly.
Displays in either step S 33 or step S34 will be described by reference to FIG. 19A. As shown in FIG. 19A, displayed on the LCD display 18 is an image including a telephone number display section 101 and a number display section 102. If the jog dial 22 is depressed while the number “9” is being displayed in the number display section 102 as shown in FIG. 19A, “9” is In addition displayed in the telephone number display section 101.
The above procedures of displaying a desired number in the number display section  102 are repeated by manipulating the jog dial 22 and depressing it for inputting the telephone number. In the event of displaying the number that the user intends to input in the number display section 102, such display will be changed depending on the direction of turning of the jog dial 22; for example, if the jog dial 22 is turned upwardly in a condition, e.g., as shown in FIG. 19A, the number displayed in the number display section 102 moves to the display condition as shown in FIG. 19C by way of the display condition as shown in FIG. 19B, thereby giving an impression that the displayed number is dragged upwardly.
As for the change in the displayed condition, the number will ultimately lose its shape and is displayed as a horizontal line as shown in FIG. 19D. If the jog dial  22 is turned downwards in the display condition, e.g., as shown in FIG. 19D, the display will change to the display condition as shown in FIG. 19G by way of the display conditions as shown in FIGS. 19E and 19F in a manner to drag the number downwards. It is to be noted that the number increments when the jog dial 22 is turned upwardly but decrements when the jog dial 22 is turned downwardly.
Such coincidence in the direction of turning of the jog dial  22 and the direction of movement of the number enables the user to easily recognize the number and avoiding any error in selecting numbers.
