Abstract
A coordinate input apparatus including transparent upper and lower strip electrodes arranged to confront each other intersectionally with a transparent press-conductive member being placed between the upper and lower electrodes. The electrode arrangement formed on a transparent substrate is fitted on a display screen, allowing the operator to press the coordinate surface by the finger tip while viewing the display. An upper and lower strip electrodes become conductive by being pressed, generating a signal which represents the pressed position on the coordinates.
