Further, the opening surface above the card insertion path 102 is covered with a metal cover 104 installed between both side portions 101a and 101a.

  As shown in FIG. 8, when the memory card 110 is inserted into the card insertion path 102, it is sandwiched between the metal cover 104 and the conductive contact 103, and a large number of electrode portions 111 of the memory card 110 correspond to each other. Each is electrically connected to the conductive contact 103.

  A concave groove 113 is formed on one side 101a of the insulating case 101 to accommodate a stopper piece 112 made of a strip-shaped metal plate. The stopper piece 112 is around the pivot pin 114 whose base end is in the concave groove 113. And is rotatably supported by the insulating case 101 around the base end. In the state where no external force is applied to the stopper piece 112, the stopper piece 112 is attached clockwise by a torsion spring 115 disposed between the stopper piece 112 and the inner surface of the concave groove 113 as shown in FIG. As a result, the leading end protrudes into the card insertion path 102.

  Thus, by attaching the stopper piece 112, the memory card 110 can be inserted only when the memory card 110 in which the portion corresponding to the protruding position of the tip of the stopper piece 112 is cut out by the taper 110b is inserted. The electrode portion 111 and the conductive contact 103 can be electrically connected.

  That is, as shown in FIGS. 9A and 9B, when the memory card 110 having the taper 110b formed on the attachment side of the stopper piece 112 is inserted into the insertion path 102, the taper 110b is formed at the tip of the stopper piece 112. And the stopper piece 112 is retracted into the concave groove 113, so that the memory card 110 can be inserted to the position shown in FIG.

  On the other hand, when trying to insert a memory card 120 that does not have a taper at the corresponding portion, as shown in FIG. 5C, the front end abuts against the tip of the stopper piece 112, and the insertion is restricted at the abutting position. Is done.

Therefore, it is possible to insert only the memory card 110 in which the electrode portion 111 is inserted in a posture that becomes the surface on the conductive contact 103 side, and the memory card 110 in the reverse orientation of the front and back, or other portions in which the corresponding portion is not tapered. It is possible to prevent the wrong type of memory card 120 from being inserted.
