Abstract
In a contact type photoelectric converter device suited for use in facsimile transmitters and character readers, a light transmitting section for transmitting light emitted from a light source is juxtaposed in the vicinity of a row of photoconductive film so that the surface of an original is uniformly illuminated and a major portion of reflected light rays from the original impinges on the photoconductive films thereby improving an efficiency of light utilization.
