<p>PURPOSE:To disconnect a power supply on the side of a main electronic apparatus to prevent a subelectronic apparatus from malfunction by stopping or suspending the disconnection of the power supply when a specific answer for a power supply disconnection request is applied from any one of devices. CONSTITUTION:A power supply request outputted from a power supply disconnection generator 5 to a main device 1 is received by a monitor 6. The monitor 6 transmits a power supply disconnection alarm message from the device 1 to subdevices 2-4 to display the message. During the passage of a prescribed time, the monitor 6 continues to monitor the existence of power supply disconnection cancel/pending commands from all the devices 1-4. When said command is received any one of the devices 1-4 before the passage of a prescribed time, the monitor 6 executes processing such as the pending of monitor or resetting of a timer during said time. When the device 1 operates the devices 2-4 on a remote position, a trouble generating malfunction in the subelectronic apparatus can be previously prevented by disconnecting the power supply on the side of the main electronic apparatus.</p> |
