ABSTRACT:
An image processing system has a reader with an image sensor, a retention memory unit connected to the reader, and a printer connected to the retention memory unit. The reader, the retention memory unit and the printer have a hierarchical control structure in order named. The retention memory unit has dynamic RAMs each of which stores image data of at least one page. The image data entered at the reader is selectively stored in the RAMs. When an operator wishes to form the image represented by the image data on a plurality of copying sheets, the corresponding original is scanned only once before copying on the first copy sheet. For the second and subsequent sheets, the image signal is selectively read out from the RAMs. The signal readout is inhibited by selectors and gates in the retention memory unit in response to logical states of corresponding flags at the end of copying.
