Abstract
PURPOSE: To make restarting of copying operation smooth and sure by controlling power source and copying machine by way of a one-chip mecroiciomputer with a built-in timer which is backed up with an external battery.
CONSTITUTION: A one-chip microcomputer 13 which is backed up with an external battery by the DC circuit provided with a buffer 14 for detection of DC potentials perorms judgement of whether the power cutoff time is within the fixed timer time of the built-in timer or not by performing interrupt processing when the power supply to a copying machine 12 is cut off owing to service interruption, malfunction, etc., and controls restarting of th copying machine 12 by determining whether the restarting condition of the copying machine after resetting of the power source is corresponded to the contents having been stored at the time of cuttoff or is corresponded to the initial condition. Hence, sopying corresponding to the conditions at the power souce cuttoff is restarted smoothly and surely and the occurrence of defective copying, etc. is prevented
