Abstract

PURPOSE:To accomplish density information through a series of readout as averaged output signals at every photoelectric conversion element, by keeping a pulse signal to be fed to a carrying gate section to off-state for a given time, and giving the function to keep the charge at a photodetection section. CONSTITUTION:A pattern sensor 6 consists of a single or a plurality of photoelectric conversion elements, or the combination of photoelectric conversion elements and an optical information transmission means such as an optical fiber, and the propriety of density information read-in is discriminated by detecting if the measuring objective appears or not with a signal discriminating circuit 7 from the amplitude of an output signal. When the density information is possible to be discriminated, a signal which turns off the pulses of a carrying gate clock for a given time is outputted from a signal generating circuit 8.
