PURPOSE:To prevent an operation error, by resetting a control means at the time of turning on an electric power supply, and after that, supplying the power to a driving means, so that a processing means can be operated. CONSTITUTION:An exposure lamp regulator 136 is connected to an output terminal OP5 through a driving circuit 126, and when a relay 117 is turned on, a signal is outputted from the output terminal OP5 by prescribed timing, and when a triode AC switch 134 is turned on, an exposure lamp 129 is lighted. It is detected by CdS 128, and is inputted to a photodetecting circuit. Also, to an output terminal OP6 is connected a solid state relay 133 for driving a cooling fan motor 131 through a driving circuit 127. When the colling fan is operated, a magnet provided on a wind pressure detection plate turns off a lead switch by a wind pressure sensor 132, and when the fan is not operated, the lead switch is turned on by the magnet. |
