Abstract
In an apparatus for detecting a coordinate position of a contact point in a touch panel, a resistance layer having a pair of electrodes opposed in a X direction and another resistance layer having a pair of electrodes opposed in a Y direction are opposed in a Z direction. The apparatus includes the following units. A unit for applying a voltage to the pair of electrodes of one resistance layer when the apparatus is in an input stand-by state. A resistance connecting an electrode of the other resistance layer to earth when the apparatus is in the input stand-by state. A unit for detecting a voltage induced to the other electrode of the other resistance layer when the resistance layers contact with each other in an event of a depressing operation. A unit for controlling the transition from the input stand-by state to another state in which an operation for detecting the coordination position is executed, when the voltage is induced to the other electrode of the other resistance layer.
