出装置。[Claims for Utility Model Registration] A. A rectangular frame formed of a light-transmitting material, and light-emitting elements and light-receiving elements arranged along the outer peripheral surfaces of mutually opposing sides of the frame. Equipped with
Optical position detection in which a light shield inserted into the frame blocks the light emitted from the light emitting element, and the light receiving element detects the light shielding position, thereby detecting the position of the light shield. B. An optical position detection device comprising means for reflecting light emitted from a light emitting element on an inner wall of the frame and preventing the emitted light from entering a corresponding light receiving element.
