And a locking means for locking the slider of the heart cam mechanism or the like to a predetermined position.

The card connector of the attaching and detaching mechanism is an arm portion in which the slider has a front end edge of the card. When the card is inserted into the outer casing, the front end edge of the card abuts against the arm portion, and the spring is resisted from coming out of the state. The slider is pushed in to move the slider to a predetermined push-in position at which the slider is locked by the locking means.

When the card is taken out, if the locking means is released, the pushing spring is pushed to move the slider in the pushing direction, and the card is brought along with the card. The arm that abuts the leading edge portion pushes the card out.

On the other hand, this card connector is based on the basis Since the size of each card insertion portion is different in the specifications of the card to be used, there is a case where a card having a smaller outer shape than a regular card is mistakenly inserted. In this case, in the above-described card connector of the conventional attachment mechanism, the arm If the length of the portion is not sufficient, the front edge portion of the arm card does not abut, and there is a possibility that the card that has been mistakenly inserted cannot be taken out.

Here, in view of this problem, the length of the extension arm is set, Even if the card is erroneously inserted, the card connector of the attachment mechanism that is in contact with the arm portion and the erroneous card is taken out by the take-up mechanism has been developed (for example, refer to Patent Document 1).
