  First, the operation of the present embodiment when the first card 100 is inserted into the case 1 will be described with reference to FIGS.

  When the user inserts the front end portion of the first card 100 into the insertion slot 2, the front end portion of the first card 100 is guided by the inclined plate portions 26A and 26B, and each of the plate portions 26A and 26B and the slider 37. Is inserted into the gap formed between the two. Since these intervals are previously made larger than the thickness of the first card 100, the front end of the first card 100 rotates the movable movable bodies 25A and 25B as shown in FIG. Without being inserted into these intervals DA and DB.

  Since the movable movable bodies 25A and 25B do not rotate, each of the pair of movable guide bodies 20A and 20B is locked by the projections 27A and 27B of the movable movable bodies 25A and 25B and held in the initial state. The That is, the distance between the pair of guide movable bodies 20 </ b> A and 20 </ b> B is maintained at a length corresponding to the width of the first card 100. Accordingly, as shown in FIGS. 10 to 13, the first card 100 moves toward the back of the case 1 while the movement in the width direction is restricted by the pair of guide movable bodies 20 </ b> A and 20 </ b> B.

  Further, as shown in FIG. 9, immediately after the first card 100 passes through the locking movable bodies 25A and 25B, the first card 100 moves in the thickness direction of the locking movable bodies 25A and 25B. It moves toward the back of the case 1 while being regulated by the portions 26A, 26B and the slider 37. 10-13, when the front end of the first card 100 passes through the tongue-like protrusions 22A and 22B of the pair of guide movable bodies 20A and 20B, these tongue-like protrusions 22A and 22B also The first card 100 moves toward the back of the case 1 while being restricted from moving in the thickness direction. The tongue-like protrusions 22A and 22B move in a direction in which the first card 100 approaches the bottom plate 9 when the first card 100 is pressed toward the bottom plate 9 with such a strong force that the plate portions 26A and 26B rotate. Will be regulated.

  Moreover, as shown in FIGS. 11-13, the 1st card | curd 100 passes on 2nd card | curd detection member 33A, 33B, and is hooked on hook 30A, 30B. After these hooks 30A and 30B are pressed by the first card 100 and slightly rotated toward the back of the case 1, the hook 30A is prevented from rotating by the lower protrusion 31 and the first guide groove 12A. Thus, the hook 30 </ b> B is prevented from rotating by the upper protrusion 32 and the guide hole 44.

  In this state, a part of the pressing force applied from the first card 100 to the hooks 30A and 30B is applied to the guide movable bodies 20A and 20B, so that these guide movable bodies 20A and 20B hold the first card 100 in place. It will be in a clamped state.

  Further, since part of the pressing force in the insertion direction applied to the first card 100 is applied to the slider 37 via the insertion restricting movable bodies 29A and 29B, the slider 37 together with the first card 100 as shown in FIG. However, it moves against the elastic force of the compression coil spring 46 (not shown in FIGS. 9 to 25). Accordingly, the guide movable bodies 20A and 20B and the insertion restricting movable bodies 29A and 29B also move toward the back of the case 1. The movement of the insertion restricting movable body 29A at this time is guided by the lower protrusion 31 of the hook 30A and the first guide groove 12A. Similarly, the movement of the insertion restricting movable body 29B is guided by the upper protrusion (not shown) of the hook 30B and the first guide groove 12B.

  Further, as the slider 37 moves toward the back of the case 1, the guide movable bodies 20A and 20B are separated from the protrusions 27A and 27B of the lock movable bodies 25A and 25B and are unlocked. However, since the first card 100 is sandwiched as described above, the movement of the first card 100 in the width direction is suppressed.

  When the slider 37 moves to the insertion limit position together with the first card 100, and thereafter the pressing force in the insertion direction with respect to the first card 100 is removed, the heart-shaped cam groove 43, the lock member 49, and the compression coil spring are removed. 46 cooperates to lock the slider 37 in place. Thereby, as shown in FIG. 15, the mounting | wearing to the case 1 of the 1st card | curd 100 is completed.

  When the user removes the first card 100 thus attached to the case 1 from the case 1, the user usually pushes the first card 100 again to the insertion limit position, and then pushes the first card 100. Do that. In this way, the heart-shaped cam groove 43, the lock member 49, and the compression coil spring 46 cooperate to release the lock of the slider 37. The unlocked slider 37 is urged by the compression coil spring 46 and moves together with the first card 100 in the ejection direction. Thereby, this embodiment returns to the state shown in FIG. That is, since the rear end portion of the first card 100 protrudes from the case 1 rather than the state where the mounting is completed, the first card 100 can be easily removed.

  Next, the operation of the present embodiment when the second card 101 is inserted into the case 1 will be described with reference to FIGS.

  When the user inserts the front end portion of the second card 101 into the insertion slot 2 as shown in FIGS. 16 and 17, the front end portion of the second card 101 is the plate portions 26A of the movable movable bodies 25A and 25B for locking. , 26B are pushed down, and these plate portions 26A, 26B are stored in the opening 10. Accordingly, the protrusions 27A and 27B of the movable movable bodies 25A and 25B move downward relative to the movable guide bodies 20A and 20B, respectively, and the movable guide bodies 20A and 20B are unlocked. .

  The front end portion of the second card 101 that has passed over the plate portions 26A and 26B presses the tapered surfaces 21A and 21B and the tongue-like protrusion portions 22A and 22B of the guide movable bodies 20A and 20B as shown in FIGS. . Accordingly, the distance between the pair of guide movable bodies 20A and 20B is increased. That is, the pair of movable guide bodies 20A and 20B are in an activated state and are allowed to move in the insertion direction of the second card 101.

  As shown in FIGS. 20 to 22, the front end portion of the second card 101 presses the respective tapered surfaces 34 </ b> A and 34 </ b> B of the second card detection members 33 </ b> A and 33 </ b> B. Accordingly, the insertion restricting movable body 29A is guided by the lower protrusion 31 of the hook 30A and the second guide groove 13A to insert the second card 101 from the insertion restricting posture that restricts the insertion of the first card 100. It changes to the permissible insertion allowable posture and is stored between the guide movable body 20A and the bottom plate 9. Similarly, the insertion restricting movable body 29 </ b> B changes to the insertion allowable posture and is stored between the guide movable body 20 </ b> B and the bottom plate 9. In other words, the second card 101 is allowed to move further into the case 1 than the first card 100.

  The front end portion of the second card 101 that has passed through the insertion restricting movable bodies 29A and 29B abuts against the inner wall surface 42 of the front end of the slider 37 as shown in FIG. 23, and the slider 37 is compressed coil spring 46 (not shown). And press against the elastic force. Thereby, as shown in FIG. 24, the slider 37 moves toward the back of the case together with the second card 101. Accordingly, the guide movable bodies 20A and 20B and the insertion restricting movable bodies 29A and 29B also move in the insertion direction. At this time, the movement of the insertion restricting movable body 29A is guided by the lower protrusion 31 of the hook 30A and the third guide groove 14A. Similarly, the movement of the insertion restricting movable body 29B is guided by the lower protrusion (not shown) of the hook 30B and the third guide groove 14B.

  When the slider 37 moves to the insertion limit position together with the second card 101 and then the pressing force in the insertion direction with respect to the second card 101 is removed, the heart-shaped cam groove is the same as when the first card 100 is inserted. 43, the lock member 49, and the compression coil spring 46 cooperate to lock the slider 37 at a predetermined position. Thereby, as shown in FIG. 25, the mounting of the second card 101 to the case 1 is completed.

  When the user removes the second card 101 thus attached to the case 1 from the case 1, the user normally releases the lock of the slider 37 in the same manner as when the first card 100 is removed. Thereby, this embodiment returns to a state like FIG. That is, since the rear end portion of the second card 101 protrudes from the case 1 rather than the state where the mounting is completed, the second card 101 can be easily removed.

  Some users do not know that they are locked, and may pull out the second card 101 without unlocking the slider 37. In this case, the insertion restricting movable body 29A moves from the third guide groove 14A to the first guide groove 12A by the biasing by the torsion coil springs 35A and 36A and the guide by the lower protrusion 31 and the fourth guide groove 15A. Insertion restriction posture. Similarly, the insertion restricting movable body 29B assumes the insertion restricting posture.

  This state is substantially the same as the state where the first card 100 is removed from the state shown in FIG. 15, and the first and second cards 100 and 101 can be mounted again. That is, when the first card 100 is inserted, the state shown in FIG. 15 is obtained directly without going through the above-described process. On the other hand, when the second card 101 is inserted, the insertion restricting movable body 29A moves from the first guide groove 12A to the third guide groove 14A and assumes the insertion permitting posture. Similarly, the insertion restricting movable body 29B is also allowed to insert. It will be in the posture shown in FIG.

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

  In the present embodiment, the guide movable bodies 20A and 20B of the movable guide means are opposed to each other in the width direction in the case 1 to form a pair. The distance between the pair of guide movable bodies 20A and 20B in the initial state is maintained at a distance corresponding to the width of the first card 100, and the distance between the pair of guide movable bodies 20A and 20B in the activated state is as follows. The distance dimension corresponding to the width dimension of the second card 101 is expanded. That is, by the cooperation of the pair of guide movable bodies 20A and 20B facing each other in the width direction of the case 1, the width dimension of the storage space of the card formed in the case 1 is narrowed, and the insertion of the first card 100 is guided. It becomes a state to do. Thus, the first card 100 can be inserted into the insertion slot 2 without being moved to one side in the width direction of the insertion slot 2. As a result, the insertability of the first card 100 into the case 1 can be improved.

  Further, in the present embodiment, each of the movable movable bodies for locking 25A and 25B locks the movable bodies for guide 20A and 20B so as to be fixed in the initial state when the first card 100 is inserted. Since the guide movable bodies 20A and 20B are unlocked at the time of insertion, the state of guiding the insertion of the first card 100 and the state of guiding the insertion of the second card 101 can be reliably switched.

  In the present embodiment, when the first card 100 is inserted from the insertion slot 2, the insertion restricting movable bodies 29 </ b> A and 29 </ b> B set the limit position of movement in the insertion direction of the first card 100 to the insertion of the second card 101. It restrict | limits to the insertion port 2 side rather than the limit position of the movement to a direction. When the second card 101 is inserted from the insertion slot 2, the insertion restricting movable body 29A is pressed by the second card 101 and allowed to be inserted from the insertion restricting posture against the elastic force of the torsion coil springs 35A and 36A. Similarly, the insertion restricting movable body 29B is pressed by the second card 101 and changes from the insertion restricting posture to the insertion allowable posture against the elastic force of the torsion coil springs 35B and 36B. The second card 101 is allowed to move deeper into the case 1 than the limit position for movement in the insertion direction. Thereby, it is possible to prevent the first card 100 from entering the back of the case 1 without disturbing the movement of the second card 101 in the insertion direction.

  In the present embodiment, when the second card 101 is inserted into the insertion slot 2, the thickness of the second card 101 is larger than the thickness of the first card 100 in the movable movable bodies 25 </ b> A and 25 </ b> B. By detecting this, the insertion of the second card 101 is detected, and the guide movable bodies 20A and 20B are unlocked. Thereby, according to the difference of the thickness dimension of the 1st, 2nd card | curd 100,101, the movable body 20A for guides and 20B can be switched reliably with lock | rock release.

  Further, in the present embodiment, when the first card 100 is pressed toward the bottom plate 9 with a force that is strong enough to rotate the plate portions 26A and 26B, the first card 100 is removed from the bottom plate by the tongue-like protruding portions 22A and 22B. The movement in the direction approaching 9 can be restricted.

  Further, in the present embodiment, the first card 100 and the second card 101 can be easily pushed out from the case 1 by the cooperation of the slider 37 with the heart-shaped cam groove 43, the lock member 49, and the compression coil spring 46. it can.

  In the present embodiment, each of the first guide grooves 12A and 12B guides the movement of the insertion restricting movable bodies 29A and 29B in the insertion restricting posture in the insertion / ejection direction, and the second guide groove Each of 13A and 13B guides that each of the insertion restricting movable bodies 29A and 29B changes from the insertion restricting posture to the insertion allowable posture, and each of the third guide grooves 14A and 14B is each of the insertion restricting movable bodies 29A and 29B. Each of the guides moves in the inserting / ejecting direction in the insertion allowable posture state. Accordingly, it is possible to prevent malfunction of the insertion restricting movable bodies 29A and 29B due to the movement of the slider 37 in the insertion / discharge direction.

  In addition, when the second card 101 is pulled out with the slider 37 being locked along with the mounting of the second card 101, the fourth guide grooves 15A and 15B are inserted into the insertion restricting movable bodies 29A and 29B, respectively. Each of the insertion restriction movable bodies 29A and 29B guides the movement to the first guide grooves 12A and 12B from the third guide grooves 14A and 14B. As a result, the first card 100 can be mounted even after the second card 101 is removed without the slider 37 being unlocked.

  In the present embodiment, the guide movable bodies 20A and 20B are assembled to the slider 37, and the insertion restricting movable bodies 29A and 29B are assembled to the guide movable bodies 20A and 20B, respectively. 20B, the insertion restricting movable bodies 29A and 29B, and the slider 37 can be assembled into the case body 5 at once. Thereby, the assemblability of the card connector can be improved.
