Abstract
A contact type image sensor provided with a case wherein a read space subject to damage by dust and a light source space less damaged by dust are completely separated from each other, and the light source space is formed with a reflecting mirror surface for effectively guiding light from the light source to an original read surface, whereby a uniform read image is obtained by the enhancement of original read performance without occurrence of deterioration in the quality of the image caused by dust.
