Contact type image sensor.

摘要

A contact type image sensor (101) includes a light source (2) for illuminating an original (1) to be read and a substrate (5,6) in which an optical fiber array member (3,4) is assembled. The substrate (5,6) is disposed such that one end of the optical fiber array member (4) faces the original (1) for transmitting a reflected light from the illuminated original (1) therethrough The contact type image sensor (101) further includes a light detecting element array (7) formed on the substrate (5,6) and facing the other end of the optical fiber array member (3) for receiving the transmitted light and converting the received light to an electrical signal. The contact type image sensor (101) also includes a driving circuit (10) disposed on the substrate (5) and electrically connected to the light detecting element array (7) for driving the light detecting element array (7).
