ABSTRACT:
This invention is to provide a PC switching device which can be applied to various kinds of PC's, some of which have an electric power control method different from the others.When a plurality of PC's621–624, the power of which are controlled by power control keys installed on keyboards are operated by single KB63without a power control key, power control switches PC-PSW1–4installed on the PC switching device61can control the power of the corresponding PC. When switches PC-PSW1–4are pressed again, main CPU610outputs a key-code to PC's621–624through sub-PC's611–614, and can control the power of PC's.
