Abstract

PURPOSE:To get rid of delay of a copying speed, by controlling a time for exposure- scanning of an original, in accordance with the size of the original. CONSTITUTION:A microcomputer 38 inputs from an input signal source 39 and a reference pulse generating circuit 41. The microcomputer 38 executes a sequence control based on these input signals and reference pulses. When a control signal is inputted through a latch circuit 43 or directly, a driving circuit 42 drives a load 44, and a driving circuit 45 drives a display part 46 by an input signal from the microcomputer 38. A stopper solenoid in the load 44 operates so as to shut-out a stopper 2 from an original passage, an electromagnetic clutch for scanning operates so as to move an exposure lamp 14 and mirrors 15, 16 at the time of exposure, and an electromagnetic clutch for return operates so as to return the exposure lamp 14 and the mirrors 15, 16 to the respective home positions.
