Abstract

Abstract In a photoelectric converter of the type having a plurality of photosensors and a plurality of signal output lines for picking up signals from the photo­sensors, wherein the signals are picked up through signal output terminals smaller in number than that of the signal output lines, the photoelectric converter is characterized by that the signal output lines each have switch means for switching the signal output line and connecting a desired signal output line to a signal output terminal.
