<p>PURPOSE:To effectively execute the automatic power source disconnection of all devices for constituting the system by using a timer having a power source disconnecting means for executing the disconnection in a specific sequence. CONSTITUTION:When a disconnection time monitoring timer 13 detects a time arrival, a disconnection time managing means 12 is actuated, and the arrival to a set time is reported to an operating state managing means 11. In the operating state managing means 11, it is judged that it is necessary to extend an operation of the system, for instance, due to a fact that work increases, and a resetting request of an automatic power source disconnection time to the disconnection time managing means 12 is executed. At the time of arriving at the reset time, the resetting processing of the disconnection time is repeated until it is judged by the operating state managing means 11 that it is unnecessary to extend an operation of the system, and when it is judged to be unnecessary, a stop of the operation of the system is requested to an operation stopping means 14, the disconnection time monitoring timer 13 is stopped, and it is requested to a power source disconnecting means 15 to disconnect a supply power source of all devices for constituting the computer system. In such a way, the automatic power source disconnection of the computer system corresponding to a daily operating state can be executed.</p> |
