Abstract

PURPOSE: To protect the function of the computer from the misoperation of the power switch by generating the interruption signals and shunting the information under being processed in case the power switch is turned off manually.
CONSTITUTION: When change-over switch 5 of power supply control circuit 2 is positioned at the local side, the function can be stopped via manual off-switch 7. The loss of the information from the IC memory or the like caused by the mistaken press of switch 7 must be avoided. When switch 7 is turned on, the interruption signal is supplied to system power supply control unit 1 from circuit 2. With this interruption signal, the prescribed shunt process is carried out to protect the information under being processed. When the shunt process is over, the end signal is generated and then transmitted to circuit 2 to turn off power supply part component unit 4.
