<p>Disclosed is an image processing apparatus in which, when the apparatus has not been not used for a prescribed period of time, control is performed so as to halt feed of current not only to a display unit and fixing heater but also to other components not required to operate when the apparatus is not in use, and in which on/off control of the power supply also can be performed through a more compact and less expensive arrangement. When a manually operated switch is being pressed by an operator, a transistor is turned on via the contacts of the switch so that power from a smoothing unit is applied to a regulator. The regulator supplies operating power to a microcomputer, which subsequently controls the status of the apparatus power supply depending upon the on/off state of an output port of the microcomputer. Supply of driving power to other components of the apparatus is achieved by opening and closing contacts through control of a relay in response to an output from another output port of the microcomputer. <IMAGE></p> |
