ABSTRACT:
A touch panel device comprises a resistance material on which a potential gradient is formed extended along an X axis, a contact electrode to be pushed to contact with the resistance material, a potential supplying unit for selectively supplying to the contact electrode via a resistance via at least two kinds of potentials one by one, a potential detecting unit for detecting the potential at the contact electrode, and a pushed position detecting unit for detecting a X coordinate of the pushed position based on the potential detected by the potential detecting unit when the potentials are supplied thereto by the potential supplying unit.
