Abstract
PURPOSE:To prevent the breakdown of a data due to an operation error, by constituting so that the electric power supply to an apparatus is cut off in response to a detection signal of an unused state of the apparatus and an operation signal of the electric power supply switch. CONSTITUTION:Whenever the processing part 2 shifts the state as stop run, and run stop, signals of set run and reset run are outputted, the FF3 detects these signals, and its output inversion RUN is made to an L or H level. That is to say, when a signal of set run has been detected, the output of the FF3 becomes an L level, the AND gate 4 is closed, on the other hand, when a signal of reset run has been detected, the output of the FF3 is made to an H level, and the gate 4 is opened. In this way, when the output of the FF3 is in an L level, even if the electric power supply switch 1 is operated, the gate 4 does not output a signal, the electric power supply unit 5 continues its operation and the processing part 2 continues its processing. After that, when the processing has been finished, the output of the FF3 becomes an H level, the gate 4 is opened, and when the switch 1 is operated, the unit 5 stops its operation.
