PURPOSE:To prevent the power supply from being interrupted during the execution of a job or before it in advance, by stopping the supply of power to a processor, when a prescribed value of a interruption indicating signal is produced in a control circuit of a power supply section. CONSTITUTION:A signal of a comparison circuit of a timer control section 3 is inputted to one input terminal of an AND circuit 11 in a central processor 7. An interruption permitting signal is inputted to the other input terminal of the circuit 11. Thus, only when an interrution request signal and the interruption permitting signal are set on at the same time, the interruption indicating signal being logical 1 level is outputted from the circuit 11. A control circuit 10 of the power supply section 8 performs the application/interruption of power supply in response to the logical value of the interruption indicating signal. The interruption permitting signal being on a logical 1 level is outputted after discriminating the operating state of the central processor and the schedule of execution of the daily job. |
