<p>PURPOSE:To reduce the capacity of a power source device by starting devices each having a large starting current at a time difference. CONSTITUTION:when a power source for a laser printer is turned ON, a main motor 4 is first started. When the lock signal SL1 of the motor 4 is input, a polygon motor 5 is started. When the lock signal SL2 of the motor 5 is input, a heater 6 and a lamp 7 are started. Thus, since the maximum value of a load current largely decreases, the capacity of the power source can be reduced.</p> |
