ABSTRACT:
A reading, printing and copying device having an image sensor for receiving a predetermined potential and a light beam reflected from an original during a predetermined control period of time, to hold or release the potential according to contents of the original. A memory stores upon reception of a memory instruction, the state of the potential of the image sensor for the following control period of time. A liquid crystal shutter allows or interrupts the transmission of copying light according to the binary level of an input print signal or the memory contents of the memory. An original reading signal output device outputs an original reading signal according to the potential of the image sensor or the memory contents of memory. A photo-sensitive copying device reproduces the original by utilizing the operation of the liquid crystal shutter so that copying light is transmitted or interrupted.
