摘要 |
<p>A reference voltage generating circuit generates +5 V and +24 V as the reference voltages, based on the voltage from the commercial power supply, i.e., AC 100 V. This reference voltage generating circuit supplies +5 V and +24 V to various operating circuits. The reference voltage of the +5 V system is supplied to a logic circuit portion and a voltage applying device. The reference voltage of the +24 V system is supplied to a control electrode voltage source for generating the voltage to be applied to the control electrode, a fixing lamp operating portion for generating the voltage to activate heater as a part of the fixing unit, and a motor operating portion for driving motors for driving various driving devices. <IMAGE></p> |
