<p>PURPOSE:To omit the faults caused by the interruption of execution by performing the control so as to inhibit the cut-off of a power supply before the processing under execution is through even though a power switch is turned off during the execution of the processing. CONSTITUTION:At a work station 11, a central processing unit (CPU) 12 is connected to a power supply part 14 via a power supply control part 16 for supply of the power supply voltage. The supply of power of the part 14 is controlled by turning on and off a power switch 13 from outside under the control of the part 16. The part 16 includes a power supply control means 17 and a process execution monitor means 18. Thus the means 17 of the part 16 detects that the switch 13 is turned off and entrusts the means 18 with a control action regardless of a fact whether the CPU 12 is carrying out a process or not. The means 18 checks the execution or non-execution of the process and the means 17 affects the part 14 to stop the supply of power when said process is through.</p> |
