ABSTRACT:
A PC card includes a plurality of functions and a plurality of CISs each for a single function or a combination of functions among the plurality of functions. A selection-signal input device inputs the CIS signal corresponding to the function to be used. A selection-signal determination section determines the designated CIS. According to the determination result, a CIS-switching setting section sets the designated CIS as the CIS to be read by a personal computer. A function-power-source switching control section supplies a power voltage only to the function corresponding to the designated CIS. An interface-bus-switching control section connects an interface bus for the function corresponding to the designated CIS to an interface bus connected to the main control section of the PC card.
