Abstract
PURPOSE: To achieve the reduction of power consumption by providing a preheating means.
CONSTITUTION: A preheating lamp PH is provided to a driver circuit 32. Then, when a main switch MSW closes, a main motor runs and at the same time a control element 3 becomes operating. A series of copying operations by way of the signals from a synchronizing signal generating part 37, microswitch group 34, wait time level control circuit 39, jam detecting circuit 40, etc. are controlled. When the copying machine is ready and a print switch is not depressed for a fixed time, a heater lamp relay HLR goes ON and a ready lamp RL goes OFF, causing the preheating lamp PH to be turned ON and a heater lamp HL1 being a spare heater to be lighted up. At the same time, heater lamps HL2, HL3 are turned OFF by the circuit 39 and the power supply to the heater lamps is limited, whereby power consumption is reduced.
