 that a key is pressed has occurred, the information generation control portion changes a key status for the key to a Press state. The information generation control portion transmits key data for the pressed key to the wireless receive device via the transmit device""s transmit portion.
The information generation control portion transmits the key data and also holds the pressed key""s status until the key is released, and determines the status whenever a defined period of time elapses. As shown in FIG. 1, if a held status does not change or a key is kept pressed, the key data which is identical to that previously transmitted is transmitted to the wireless receive device.
As such, with a key being pressed, wireless data is transmitted whenever the defined period of time elapses. If a key status is held in the Press state, the wireless receive device expects that the wireless transmit device should transmit the same data at least once whenever the defined period of time elapses.
If the same data is not received from the wireless transmit device within the defined period of time, then the operation portion determines that a failure has occurred in a communication channel, and the operation portion, with an auto-repeat condition entered, cancels such state and, without the auto-repeat condition entered, prevents the state from being entered.
A description will now be provided of a wireless information transmission system with a wireless transmit device and a wireless receive device each having a transmit portion and a receive portion. When an event that a key is pressed has occurred, the information generation control portion of the wireless transmit device, as well as that of the previously mentioned wireless information transmission system, changes the key""s status to a Press state and transmits key data to the wireless receive device via the transmit device""s transmit portion.
The information generation control portion, until a pressed key is released, transmits the same data as previously transmitted key data or status information indicating the same input provided via a key, to the wireless receive device repeatedly at predetermined intervals.
With any key held in the Press state, the wireless receive device expects that it should receive the same data from the wireless transmit device at least once whenever a predetermined period of time elapses. However, if within the predetermined period of time the wireless receive device does not receive from the wireless transmit device the same data or a status indicating the same input provided via a key, then the wireless receive device""s operation portion determines a failure has occurred in a communication channel. Then to check such failure the wireless receive device transmits control data (a request to retransmit
that a key is pressed has occurred, the information coevals restraint portion changes a key condition for the key to a Press state. The information coevals control portion convey key data for the pressed keystone to the wireless receive device via the transmit device""s air portion. 
 The information generation control portion convey the key data and also defend the pressed key""s status until the key is released, and determines the condition whenever a defined menstruation of time elapses. As shown in FIG. 1, if a held status does not transfer or a key is kept pressed, the key data which is identical to that previously transmitted is transmitted to the wireless receive device. 
 As such, with a key being pressed, wireless data is transmitted whenever the defined period of time elapses. If a key status is apply in the Press state, the wireless receive device expect that the radio transmit device should transmit the same data at least once whenever the defined period of time elapses. 
 If the like data is not received from the wireless transmit device within the defined period of time, then the operation portion determines that a failure has occurred in a communication channel, and the process portion, with an car - repeat circumstance accede, cancels such state and, without the auto - repeat circumstance entered, prevents the state from being entered. 
 A description will now be provided of a wireless information transmission system with a wireless transmit device and a radio receiver receive device each having a transmit part and a receive portion. When an consequence that a key is pressed has occurred, the information genesis control portion of the wireless transmit device, as well as that of the previously mentioned wireless data transmission system, changes the key""s condition to a Press state and transmits key data to the radio receive device via the transmit device""s transmit portion.
