Image reading apparatus

Abstract

An object of the invention is to provide a small-size image reading apparatus which has a high accuracy in image reading, by a different means from the prior arts. A panel includes a plurality of two-dimensionally arranged photoreceptor devices which are interposed between a pair of light-transmitting substrates. At an edge of one of the light-transmitting substrate, a slope is formed, and a light source is opposed to the slope. Light transmitted by reflection on the surfaces of the light-transmitting substrates is emitted on an object which comes in contact with the surface of the panel, and light returned from the object is received by the photoreceptor devices, whereby an image of the object is read. Thus, a direction in which light passes through the panel can be restricted, and the accuracy in image reading can be increased.
