Accordingly, the slider 36 is biased by the compression coil spring 40 and moves to the initial position (position shown in FIG. 8) while pushing the narrow card 50 out of the case 1. In this way, the user picks the rear end portion of the narrow card 50 extruded from the case 1 and removes it from the case 1.

  As shown in FIG. 12, when the first wide card 60 is attached to the case 1, the user forms the front end of the first wide card 60 by the second spacing portion 13 and the third spacing portion 14 of the insertion slot 11. The card is inserted into the wide card insertion portion 16 from the opening.

  The first wide card 60 inserted into the wide card insertion portion 16 in this way contacts the left movable movable body 22A as shown in FIG. 12 at the front end of the left side portion. In this state, when the user presses the first wide card 60, as shown in FIG. 13, the front end of the left side of the first wide card 60 resists the urging of the locking movable body 22A by the torsion coil spring 27A. And moving toward the back of the case 1 while changing the posture of the movable movable body 22A to the release posture.

  After the front end of the left side portion of the first wide card 60 passes through the locking movable body 22A, the front end of the right side portion of the first wide card 60 contacts the right locking movable body 22B as shown in FIG. . In this state, when the user presses the first wide card 60, as shown in FIG. 14, the front end of the right side portion of the first wide card 60 resists urging by the torsion coil spring 27B, and the movable movable body 22B for locking. , That is, while moving the locking movable body 22B to the release posture, the case 1 moves toward the back of the case 1 (see FIG. 23).

  As shown in FIG. 14, in a state where both of the locking movable bodies 22A and 22B are in the released posture, that is, in a state where the locking of the insertion blocking movable body 17 is released, the insertion blocking movable body 17 is a torsion coil spring. 21 is held in the insertion prevention posture. Therefore, when the user presses the first wide card 60, the front end of the first wide card 60 biases the plate portion 18 of the insertion preventing movable body 17 by the torsion coil spring 21 as shown in FIG. It moves toward the back of the case 1 while pushing down against it. At this time, the pushed-down plate portion 18 is in a state of being retracted into the narrow card insertion portion 15 outside the insertion track of the first wide card 60 as shown in FIG.

  Further, as shown in FIGS. 15 and 16, the front end of the left side portion of the first wide card 60 passes through the insertion preventing movable body 17 and then is urged by the torsion coil spring 35A via the first rotating member 29A. It moves toward the back of the case 1 while rotating the second rotating member 32A against the above. Accordingly, the guide movable body 28 </ b> A changes to a retracted posture folded linearly on the left side in the case 1.

  The front end of the right side of the narrow card 50 is a torsion coil spring via the first rotating member 28B from the middle of the front end of the left side of the first wide card 60 changing the guide movable body 28A to the retracted posture. It moves toward the back of the case 1 while rotating the second rotating member 32B against the urging force by 27B. Along with this, the guide movable body 28 </ b> B changes to a retracted posture folded linearly on the right side in the case 1.

  When the first wide card 60 moves further toward the back of the case 1 after changing both of the guide movable bodies 28A and 28B to the retracted posture, the wide card receiving portion of the slider 36 as shown in FIG. Reach 38. Thereafter, the first wide card 60 is pressed by the user and moves toward the back of the case 1 together with the slider 36 against the urging by the compression coil spring 40.

  Then, as shown in FIG. 18, when the first wide card 60 and the slider reach the insertion limit position, the user stops pressing the first wide card 60. Accordingly, the slider 36 is urged by the compression coil spring 40 and moves from the limit position in the discharge direction to the predetermined position shown in FIG. 19, and the heart-shaped cam groove 41 and the lock member 42 cooperate at this predetermined position. Locked by. That is, the state shown in FIG. 19 is a state in which the first wide card 60 is completely attached to the case 1, that is, the first wide card 60 is in contact with the terminal group 6 at an appropriate position.

  In the state where the first wide card 60 is attached to the case 1, the slider 36 resists the urging of the slider detection member 44 by the coil spring 45 in the same manner as when the narrow card 50 is attached to the case 1. The coil spring 45 is deformed and is in contact with the fixed contact.

  When the first wide card 60 is attached to the case 1, the write protect detection member 46 is pressed in the direction of the bottom plate 3 depending on the position of the operation member (not shown) in the notch 61 of the first wide card 60. It is operated or not operated. If the write protect detection member 46 is pressed, the coil spring 47 is deformed and is in contact with the fixed contact.

  When removing the first wide card 60 from the case 1, the user presses the first wide card 60, moves it together with the slider 36 to the insertion limit position of the case 1, and then presses the first wide card 60. Stop doing. During this time, the slider 36 is unlocked by the cooperation of the heart-shaped cam groove 41 and the lock member 42. Accordingly, the slider 36 is biased by the compression coil spring 40 and moves to the initial position (position shown in FIG. 17) while pushing the first wide card 60 from the case 1. In this way, the user picks the rear end portion of the first wide card 60 pushed out from the case 1 and removes it from the case 1.

  Since the case where the second wide card 70 is attached to the case 1 and the case where the second wide card 70 is removed from the case 1 are substantially the same as the case of the first wide card 60, description thereof will be omitted. . However, the first wide card 60 and the second wide card 70 have different positions for pressing the movable movable bodies 22A and 22B when operating the movable movable bodies 22A and 22B. This difference will be described.

  21 to 23, the first wide card 60 is first brought into contact with the left movable movable body 22A, and the left movable movable body 17 is rotated by rotating the movable movable body 22A. Release the lock. Next, the locking movable body 22B is brought into contact with the right locking movable body 22B, and the locking movable body 22B is rotated to release the right locking of the insertion preventing movable body 17.

  Further, as shown in FIGS. 24 to 26, the second wide card 70 is first brought into contact with the left movable movable body 22A, and the movable movable body 22A on the left side is rotated to rotate the left movable movable body 17A. unlock. Next, the locking movable body 22B is brought into contact with the right locking movable body 22B, and the locking movable body 22B is rotated to release the right locking of the insertion preventing movable body 17.

  Thus, when each of the operations of the movable movable bodies 22A and 22B for locking accompanying the insertion of the first and second wide cards 70 is viewed from above, the first wide card 60 and the second wide card 70 are similarly operated. It appears that the locking movable bodies 22A and 22B are rotated.

  However, as shown in FIGS. 27 and 28, the front end of the left side portion of the first wide card 60 presses the second operating portion 26 </ b> A of the movable movable body 22 </ b> A with the thin portion 61 </ b> A, and the movable movable body with the thick portion 63. The first movable portion 22A of 22A is pressed to rotate the locking movable body 22A. On the other hand, the front end of the left side portion of the second wide card 70 has a second operational portion as shown in FIGS. The movable movable body 22A is rotated by pressing only 26A. The same applies to the case where each of the first and second wide cards 60 and 70 rotates the locking movable body 22B.

  According to this embodiment, the following effects can be obtained.

  The guide means, that is, the guide movable bodies 28 </ b> A and 28 </ b> B restrict the movement of the narrow card 50 in the direction away from the terminal group 5 from the wide card insertion portion 16. By obtaining the contact pressure between the narrow card 50 and the terminal group 5 in this way, a card connector that can easily secure the contact pressure between the narrow card 50 and the terminal group 5 can be realized.

  In addition, since the guide movable bodies 28A and 28B advance and retreat in the width direction of the case 1, an increase in the thickness dimension of the case 1 accompanying the provision of the guide means can be suppressed.

  In addition, the guide movable body 28A is constituted by the first and second rotating members 29A and 32A supported at different positions in the depth direction of the case 1, and similarly, the first movable member 28A supported at different positions in the depth direction of the case 1. Since the guide movable body 28B is composed of the first and second rotating members 29B and 32B, the strength of the guide movable bodies 28A and 28B against the force received from the narrow card 50 can be improved.

  In addition, since each of the guide movable bodies 28A and 28B is linearly folded on each of the left and right side portions in the case 1, an increase in the width of the case 1 due to the provision of the guide means can be suppressed.

  Further, since the second rotating members 32A and 32B of the movable guide bodies 28A and 28B are provided in the vicinity of the insertion preventing movable body 17, the front end of the narrow card 50 has passed through the insertion preventing movable body 17. Immediately thereafter, the movement of the front end of the narrow card 50 in the direction of the wide card insertion portion 16 can be restricted.
