えてなることを特徴とする光学的入力装置。 A plurality of pairs of light sources and light receiving elements are arranged at least on one side of the position detection surface with a predetermined distance between them,
An auxiliary light receiving element and a light distribution means corresponding to each of the light sources are provided on a side opposite to one side of the position detection surface, and
The light sent from the light source is distributed to the light receiving element paired with the light source, and a part of the light is distributed to the auxiliary light receiving element corresponding to the light source, and the light is distributed to the light receiving element and the light receiving element paired with the light source. an optical path from the light source to the corresponding light distribution means when receiving a signal from the auxiliary light receiving element and the light from the light source is not received by the corresponding auxiliary light receiving element and the light receiving element paired with the light source; However, when only the corresponding auxiliary light-receiving element receives light from the light source, the light-path determining means determines that each optical path from the light distribution means to the light-receiving element is blocked. An optical input device characterized by:
