Abstract:
A PC card comprising:a function block providing a predetermined function for an information processing device;a first interface section executing a data transfer between the function block and a first information processing device;a second interface section having a different specification from the first interface section, the second interface section executing a data transfer between the function block and a second information processing device;a plurality of signal lines having at least a first signal lines connected to the first interface section, a second signal lines connected to the second interface section, and a common signal lines connected to the function block by being commonly connected to both of the first and the second signal lines through a junction section, the plurality of signal lines connected from the function block to the first interface section and/or the second interface section; anda switching means for selecting one of the first or second interface section and connecting the selected one to the function block;wherein the switching means has a signal line switching section to electrically connect the common signal lines to only one of the first or second signal lines on the basis of a first power source voltage supplied from the first information processing device to the first interface section and a second power source voltage supplied from the second information processing device to the second interface section.
