PURPOSE:To make timing control system simple and prevent image position deviation by performing the start of a resist roll by means of an axternally installed switch in the copying machine which is clocked and sequence controlled by a microcomputer. CONSTITUTION:When an exposure switch SW1 is closed at the original scanning, the plural timers for clocking of a microcomputer start and the clocking and the sequence control of the copying machine are accomplished. As the scan of the original progresses further, the switch 44 installed to the outside goes ON at the specified timing through the mover at the scanning, causing a transistor 44 to conduct and the resist roller to be started by a solenoid 43. Hence, the clocking and the sequence controlling are accomplished by the microcomputer and the starting of the resist roller is accomplished by the external switch which operates during sequence operation, thus the need for clocking of the time for resist roll start reference is eliminated. As a result of this, the timing control system becomes simple and the image deviation caused by routine errors is prevented. |
