ABSTRACT:
A photoelectric converting device having a plurality of line sensors, each line sensor having an output line and scanning means for scanning that line sensor. Selection circuit selectably directs a signal from one of the plural output lines to a common output terminal. A reset device resets the common output line to a predetermined level in response to the scanning of the line after the signal has been directed to the common output terminal. The readout may be conducted by scanning the plurality of line sensors by alternatively scanning photoelectric conversion cells from different line sensors.
