ABSTRACT:
A coordinate input device includes an input surface in the form of a rectangle and a face-plate switch. The input surface is formed by overlapping a first input detecting member and a spaced second input detecting member. When the input surface is pressed, resistive surfaces of the first and second input detecting members contact each other, and that X-Y coordinate input on the input surface is obtained from the resistance detected at a first or second resistor of the first input detecting member and the resistance detected at one of two other resistors associated with the second input detecting member.
