Description

  The present invention relates to a card connector device on which first and second cards having different dimensions are selectively mounted.

  As a conventional card connector device, there is a conventional technique disclosed in Patent Document 1. This prior art includes a case in which different types of first and second cards are selectively inserted.

The length of the second card in the insertion direction into the case is shorter than that of the first card, the width of the second card is substantially equal to that of the first card, and the shape of one side of the end is different from that of the first card.

  A card discharge mechanism is provided in the case for moving the first card and the second card attached to the case in the discharge direction. The card discharge mechanism includes a slide member that can slide a space in the case including the insertion track of the first card in the insertion direction of the first and second cards and a discharge direction opposite to the insertion direction, and the discharge direction. And an elastic member for biasing the slide member. Further, the card discharge mechanism stops the slide member at a position deviated from the mounting area in the case occupied by the first card when the first card is mounted on the case, or releases the stopped state. Can be done.

  The slide member is provided with a movable member. The movable member is rotatable in the width direction of the case corresponding to the width direction of the first and second cards, and can protrude into the insertion track of the second card. The movable member is biased by an elastic member in a direction protruding into the insertion track of the second card. The movable member is further pushed away by one side of the front end of the first card moving in the insertion direction in the direction of retreating from the insertion path of the first card, and one of the front ends of the second card moving in the insertion direction. It is shaped to be caught on the side.

  In the related art configured as described above, when the first card is inserted into the case, one side portion of the front end portion of the first card that moves in the insertion direction opposes the movable member against the elastic force of the elastic member. Since it pushes away, the front-end part of a 1st card | curd passes the position of a movable member in an insertion direction, and contact | abuts to a slide member. The first card moves while sliding the slide member in the insertion direction against the elastic member. Thereafter, the slide member stops and the first card is completely installed.

  On the other hand, when the second card is inserted into the case, one side portion of the front end portion of the second card is caught by the movable member. The second card moves while pressing the movable member while sliding the slide member in the insertion direction against the elastic member. Thereafter, the slide member stops and the mounting of the second card is completed.

That is, the position where the second card pushes the slide member is set in front of the first card by the movable member. As a result, the second card at the completion of the mounting is positioned before the position of the first card at the completion of the mounting. That is, the second card is prevented from entering the back of the case too much.
JP-A-2005-190984

  By the way, it is possible to selectively mount the first card and the second card having all of the length, width and thickness dimensions shorter than those of the first card on the card connector device. It is requested.

  In the prior art described above, the first and second cards are positioned in the respective insertion directions by the movable member. However, the movable member is resisted against the elastic force of the elastic member by twisting the second card in the width direction. Since it can push away, there exists a possibility that a 2nd card may enter into the back of a case too much. If the same structure as the mechanism including the movable member and the elastic member in the prior art is adopted as the card connector device for meeting the demand, the width of the second card is shorter than the first card. Thus, it is possible that the situation where the second card is too much in the back of the case is more likely to occur.

  The present invention has been made in consideration of the above-described actual situation, and the object of the present invention is to provide a first card and a second card that is shorter in length, width, and thickness than the first card. An object of the present invention is to provide a card connector device that can be selectively mounted and can prevent the second card from being excessively inserted into the back of the case by prying.

  In order to achieve the above object, the present invention is configured as follows.

And the first and second lock members constitute a cam mechanism, and the cam mechanism moves from the lock position to the release position. The movement of the first locking member in this direction is linked to the movement of the second locking member in the direction from the retracted position toward the protruding position, and the first locking member in the direction from the protruding position toward the retracted position. The movement of the first lock member may be interlocked with the movement of the two lock members in the direction from the lock position toward the release position.

  In the present invention configured as described above, the first card and the second card whose length, width, and thickness are all shorter than the first card can be selectively mounted, and the first card can be removed by prying. It is possible to reliably realize a card connector device that can prevent a situation where two cards enter the back of the case too much.
