Then, when the first card 1 is mounted on the predetermined mounting portion 3 b of the housing 3, the length of the end portion of the first card 1 that goes out from the insertion port 3 a of the housing 3 and the predetermined amount of the housing 3 are determined. When the second card 2 is mounted on the mounting portion 3b, the length of the end of the second card 2 that goes out from the insertion port 3a of the housing 3 can be made substantially the same.

  According to the present embodiment, when the second card 2, which is a short card, is pushed in, the first contact terminal 4 is secondly moved by the cam mechanism including the plate-like portion 16b and the cam portion 16d of the guide member 16. The card 2 is pushed down so as not to contact the contact portion 2b. That is, it is possible to prevent contact between the second card 2 that is a short card and the first contact terminal 4 provided in association with the first card 1 that is a long card that should not be contacted. Can prevent malfunction. Thus, a highly reliable card connector device can be realized. Further, it is possible to reduce the size of the device by arranging the first contact terminal 4 and the second contact terminal 5 close to each other.

  Further, since the cam mechanism has a simple configuration including a plate-like portion 16b that is a part of the guide member 16 and a cam portion 16d fixed to the plate-like portion 16b, the cam mechanism can be easily manufactured. is there.

  Further, in the present embodiment, even when the second card 2 is pushed and the slide member 6 is overstroked in order to eject the second card 2 mounted on the predetermined mounting portion 3b, the above-described cam mechanism is used. No contact between the 2 card 2 and the first contact terminal 4 occurs.

  In addition, the slide member 6 includes a torsion coil spring 9 that forms a movable contact, a common contact 10, a first fixed contact 11, a second fixed contact 12, and an insulating region 13. The slide member 6 has a predetermined discharge position and a lock position. And a detecting means capable of detecting that it is in the locked position, and further capable of detecting that it is in the overstroke position.
