摘要
To enable a power to the computer to be shut down in a simple configuration and independently of the status of the computer. The power switch 46 is set at the normal position while the computer 10 is operating. Each of the power, reset, and function signals is thus on the high level (A). When the function key 42A is pressed in that status, the function signal can be shifted to a low level signal so as to validate only the key 42A (B). While the power switch 46 is shifted to a pointed position and the key 42A is not pressed, only the power signal is validated, thus a power-on or power-off command can be issued (C). If the power switch 46 is set at a pointed position and the key 42A is pressed, then the level of the reset signal becomes low, thereby the reset signal is validated with the key 42A (D). Consequently, the power to the computer can be shut down forcibly if the power switch 46 is set at a pointed position and the key 42A is pressed, regardless of the status of the computer 10 operation.
