Abstract
A photoelectric transducer device including a plurality of sensor elements made up of photodiodes and blocking diodes on a substrate, connected into a linear pattern which extends in a primary scanning direction, the sensor elements to be driven in a suitable sequence to read image data from an original document. Each sensor element include a first lower electrode formed on the substrate, a second lower electrode, formed on the substrate and electrically separated from the first electrode, a photodiode formed on the first electrode, a blocking diode formed on the second electrode for preventing crosstalk, and an upper electrode formed on the photodiode and blocking diode for electrically connecting them. Lead wires for connecting the sensor elements to output circuits extend in the primary scanning direction on the first lower electrodes with an insulating film in between, the first lower electrodes being selectively connected to the lead wires through holes provided in the insulating film.
