Abstract
PURPOSE:To prevent the accident of apparatus by storing the interruption program for letting forming operation be accomplished as desired into a memory in addition to the main program for codntrolling image forming operation thereby codntrolling the operation. CONSTITUTION:An interruption board IA is made higher in priority than the same IB and a trouble detector is connected to the board IA and a clock generator to IB so that when the FFs of the boards IA, IB are held set and the interruption signal is inputted first to the IA then the FFs of the IA, IB are reset and the ROM program of the address assigned by the IA is executed. As a result, when the clock signal is inputted to the IB first, only the FF thereof is reset and therefore when the trouble signal is generated in the IA, the trouble signal is inputted to stop the operating apoaratus irrespective of the interruption applied to the IB. Thereby, the accident of the copying machine may be prevented.
