Abstract

PURPOSE:To obtain the coincidence between display information of a coordinate input device and picture information, by detecting a coordinate position by the change of the resistance value from a contact point between a transparent resistor and a transparent conductor to a set position of a voltage detector. CONSTITUTION:When a transparent conductor 1 to which a potential +V is applied is depressed in accordance with guidance, the potential +V is supplied to a transparent resistor 2. The potential +V applied to a point A passes through a resistance RX of the transparent resistor 2 and a resistance R to flow a current (i), and a divided potential E of the voltage +V is obtained in the input of a voltage detector D. The contact position between the transparent conductor 1 and the transparent resistor 2 is changed to obtain different potentials E in the input of the voltage detector D, and thus, the contact position is detected.
