ABSTRACT:
A PC Card input/output device comprises a PC Card connector including a socket portion into which a PC Card can get inserted. The socket portion contains a switch which can be fully accommodated within a space defined by inner walls of the socket portion and a notch formed on a PC Card inserted if the upper and lower sides of the PC Card inserted are oriented in proper directions with respect to the socket portion, and which can be mechanically actuated so as not to prevent insertion of a PC Card if the upper and lower sides of the PC Card inserted are oriented in improper directions with respect to the socket portion, so that the switching state of the switch is changed. When the switch state of the switch is changed, a connection switching unit can change a connection between the plurality of connecting terminals of the PC Card connector and a plurality of terminals with which the connection has been set up, before the PC Card inserted is electrically connected to the PC Card connector.
