1. An input device comprising: a planar input that generates a coordinate input operation; an indicator section provided at a surface of the planar input, the indicator section having a plurality of input sections; and a control section that generates an operation signal in accordance with an input signal that the control section has received from the planar input, wherein, when the input device is set in ma first input mode, the control section detects that any one of the input sections has been touched, and generates an operation signal in accordance with a prescribed item of the input section, and, wherein, when the input device is set in a second mode, the control section recognizes the input signal from the planar input as coordinate data regardless of what is indicated at the touched input section.
