を特徴とする密着型イメージセンサー。 A light source that illuminates a document to be read, a light receiving element that converts light reflected from the document into an electrical signal, and at least light from an optical path connecting the light source and the document reading surface is transmitted across and receives the light reflected from the document. An optical fiber array is provided between the original and the light receiving element so as to guide the light to the light receiving element, and the optical fiber array is installed so that the side surface of the optical fiber array on the light source side is located at the back so as to be separated from the light source. A close-contact image sensor characterized by:
