PURPOSE:To improve the reliability of a device by resetting both microcomputers if a signal outputted from a controller including plural microcomputers is not in a desirable state. CONSTITUTION:When the sequence control of a copying machine is executed by using plural microcomputer, for example, it is confirmed whether the resetting of one microcomputer is completed at the time of completing the resetting of another microcomputer, so that it can be prevented that copying actions are unstably executed by running the microcomputer in a state where one microcomputer is not cleared to an initial state. In other words, security can be kept since the power supply to load by turning on a main switch can be executed after confirming that one microcomputer or both of them complete the resetting and normally actuate and the power supply to the load is prevented if the control system of a machine is in a incomplete state. |
