Claims

[Claims for Utility Model Registration] A plurality of light emitting elements are arranged around a light receiving element, the light emitted from the light emitting elements is received by a retroreflective sheet, and the light receiving element is reflected by the retroreflective sheet. In the optical instruction input device adapted to receive light, the reflective surface of the retroreflective sheet is initially arranged to be substantially perpendicular to the optical axis of the light emitted from the light emitting element, and after a predetermined time has elapsed, the reflective surface of the retroreflective sheet An optical instruction input device characterized in that a switching operation is performed by making a reflective surface of a reflective sheet substantially parallel to the optical axis so as not to receive light emitted from the light emitting element.
