Abstract
A coordinate-detecting device of a voltage-detecting type, the device including: a coordinate input pad having an upper sheet and a lower sheet opposing each other at a predetermined gap, the sheets being in electrical contact when there is a touch on the coordinate input pad; a voltage-detecting part for alternately detecting voltage values representing an X-coordinate and a Y-coordinate of a contact point; and a control part for generating a coordinate data from the voltage values detected at the voltage-detecting part. The upper sheet and the lower sheet oppose each other at the predetermined gap by a repulsive force between magnetic poles with the same polarity.
