Since the voltage is converted into a voltage and the operating voltage is supplied to the peripheral device 300, it is not necessary to provide a voltage converter according to the operating voltage of the peripheral device 300 in the PC body 100. In addition, by preparing a plurality of types of connection cables 200 each having a voltage converter capable of outputting a different operation voltage, when the operation voltages of the peripheral devices 300 are different, the connection according to the peripheral device 300 is performed. Since it can be dealt with simply by replacing the cable 200, the PC main body 100 can be downsized because there is no need to provide a plurality of voltage converters corresponding to peripheral devices connected in the PC main body 100. Furthermore, in the case of peripheral devices having the same operating voltage, one connection cable can be shared, so that cost reduction can be achieved.
