1. An information processing apparatus for use in receiving an information storage device that includes a semiconductor storage medium with a first portion having an external connection terminal and a second portion including a state-designating portion for designating a state in which writing of information to the semiconductor storage medium is prohibited, the information processing apparatus comprising:

  • an external support member having a cavity therein, at least one side wall of the external support member having an opening for receiving the information storage device;

    a plurality of first connector pins, positioned in the cavity, for providing an electrical connection with the information storage device, to retrieve the information from the semiconductor storage medium;

    a plurality of second connector pins, positioned in the cavity, for providing a contact with the state-designating portion, a physical position of the plurality of second connector pins with respect to the opening being closer than a physical position of the plurality of first connector pins with respect to the opening; and

    a discriminating circuit operably coupled to the plurality of second connector pins for discriminating whether writing information to the semiconductor storage medium is prohibited by detecting conductive/non-conductive state between the plurality of connector pins.
