PURPOSE:To enable reduction in warm-up time by providing a control means which turns a main motor on and off according to whether the input state of an input means attains a prescribed temp. or not in the stage of throwing an electric power source. CONSTITUTION:A microcomputer 6 and a comparator 7 which compares the reference voltage set at the level signal of a fixing temp. T2 from an output port PO1 or the reference voltage set at the level signal of the prescrived temp. T1 lower than T2 from an output port PO2 and the comparison voltage which changes with the resistance value from a thermistor 3 are provided to a control circuit. A transistor 8 is turned on by the output signal from a comparator 7 when the comparison voltage is above the reference value. A wait lamp 9 is lighted by the signal from an output port PO3. A main motor 4 and a heater 2 are respectively turned on when photocouplers PC1, PC2 are operated by the signals from output ports PO4, PO5. |
