<p>PURPOSE:To eliminate the need to make adjustments by an external resistance for matching a detected value with A/D conversion resolution by the coordinate input device as to a difference in the number of XY pixels, to simplify circuit constitution at the time of plane switch input, and to speed up processing. CONSTITUTION:A Y-directional input detection member is so constituted as to apply voltages to a resistance surface RY for coordinate detection between a 1st electrode 1a and a 3rd electrode 1c and a resistance part RHS for detecting plane switch operation. Further, the resistance values of the resistance surface RY and resistance part RHS are so set to use the resistance part for detecting the operation of the plane switch 30 as a correction resistance.</p> |
