ABSTRACT:
A contact type image sensor comprises a photoconductive layer sandwiched between a first electrically conductive layer and a plurality of second separate electrodes to form a plurality of light receiving elements comprising a plurality of buffer amplifiers each connected to corresponding one of the plurality of light receiving elements for respectively outputting a voltage whose value corresponds to electric charge stored in the corresponding light receiving elements, switching means for gating the outputs of the buffer amplifiers, and control means for controlling the switching means to lead the outputs of the buffer amplifiers to a signal output line sequentially.
