It comes to allow. The interlocking limit position S2 is a limit position in the pushing direction of the slider 20 in which the slider 20 can move together with the card-like body 2.

  The lock guide path 53 is formed in an oblique shape from the front side portion of the push-in operation allowing portion 52 toward the engagement recess 44 side, and is formed at the bottom of the terminal end so that the engagement recess 44 side is sequentially lowered. A stepped guide step portion 61 is formed, and the regulation pin portion 33 is guided to the guide step portion 61 and dropped into the engagement recess 44 from the return prevention step portion 57.

  The release guiding path portion 54 is formed in a straight line shape in the pushing direction from the engagement concave portion 44, and a return inclined portion 62 that is inclined so that the end side becomes higher is formed at the end bottom portion, and the restriction pin portion 33 prevents the return. The slider 20 is pushed back in the pushing direction by the urging force of the pushing spring 25 so that the engaged state with the heart cam 42 cannot be released unless it falls from the stepped portion 58 to reach the return path portion 51.

  A return prevention step 58 (hereinafter referred to as a release return prevention step 58) that restricts the movement from the return path 51 to the release guide path 54 is a slider movement from the position P4 of the restriction pin 33 at the interlocking limit position S2. The restricting pin portion 33 is formed in a position shifted to the rear side in the direction, and the restricting pin portion 33 is returned to the return portion 51 only when the slider 20 is detached from the card-like body 2 and moved from the interlocking limit position S2 to the lock release position S4 in the rearward direction in the pushing direction. It moves to the position P5 on the side.

  As a result, the amount of movement of the slider 20 in the pushing direction during the card-like body removal operation is longer than the amount of movement of the slider 20 in the pushing direction during the card-like body insertion operation.

  The return path portion 51 is formed in a bent shape corresponding to the side shape of the heart cam 42, and is a guide step formed in a stepped shape so that the combined path portion 55 side is sequentially lowered at the junction with the combined path portion 55. A portion 63 is formed, and the regulating pin portion 33 is guided to the combined path portion 55 in conjunction with the movement of the slider 20 by the urging force of the push spring 25, and returns to the origin position P1.

  As shown in FIG. 8, the card-like body 2 includes a flat tray main body 70 and a front edge lid 71 disposed on the near side of the tray main body 70 in the tray insertion / extraction direction. It is joined to the tray insertion / removal direction end part of the tray main body 70 through the made joining members 72 and 72.

  The tray main body 70 is formed in a flat plate shape with an insulating synthetic resin material, and a concave card accommodating portion 73 in which the card A is accommodated is formed on one side portion.

  Further, the inner edge of the tray body 70 in the tray insertion / removal direction constitutes a stopper portion 75 that is stopped by the stopper protrusion 74 disposed on the inner side of the mold body 10 in the pushing direction, and the card body 2 is The position at which the stopper 75 is stopped against the stopper protrusion 74 of the housing 4 when inserted into the housing 4 is defined as the card-like body pushing limit position, and the card-like body 2 is pushed from the card-like body pushing limit position. The movement to the side is regulated.

  Further, the tray body 70 is formed with an engagement notch 76 into which the interlocking engagement portion 22 of the slider 20 is fitted at the back side in the tray insertion / removal direction, and the inner edge of the engagement notch 76 and the interlocking engagement portion 22 are formed. When the interlocking engagement piece 26 abuts the inner edge of the tray main body 70 in the tray insertion / removal direction, the pushing force acting on the card-like body 2 can be transmitted to the slider 20 and acting on the slider 20. The urging force by the pushing spring 25 is transmitted to the card-like body 2.

  Therefore, the slider 20 moves independently together with the card-like body 2 in a state where the interlocking engagement portion 22 is fitted to the engagement notch 76 and is released by moving the slider 20 toward the pushing side relatively. It is like that.

  In the figure, reference numeral 77 denotes an exposed portion for switch contact, and the back side edge of the card A is exposed through the notch 77, and the back side edge of the card A is disposed on the back side of the housing 4. The operation contact 78a is contacted with or disengaged from the operated contact 78b by contacting and pressing the operation contact 78a constituting the detected switch 78, whereby the switch 78 is turned on / off, and the card A Insertion can be detected.

  The front edge cover body 71 is formed in a rectangular parallelepiped shape, and an insertion guide hole 79 penetrating in the card-like body 2 insertion / extraction direction is formed on one side, through the insertion guide hole 79, the side of the housing 4, that is, the slider movement A pin-like key member 80 can be inserted from the front opening of the portion 14.

  Next, the insertion operation of the card-like body 2 will be described based on FIG. 9A shows a state in which the card-like body 2 is pulled out from the housing 4. The slider 20 is urged by the pushing spring 25 and is at the origin position S1 shown in the drawing. It is at the origin position P1 on the near side of the combined road portion 55 in the guide groove 42.

  9B, when the card-like body 2 is inserted to a predetermined position in the card-like body insertion portion 3, the interlocking engagement portion 22 of the slider 20 is fitted into the engagement notch portion 76. In addition, the protrusion 31a of the half lock piece 31 engages with the half lock recess 32, and the card-like body 2 and the slider 20 are integrated in a detachable state. At that time, when the regulation pin portion 33 is in the forward path portion 50 and the pushing force is released, the slider 20 is pushed back to the origin position S1 by the urging force of the pushing spring 25.

  If the card-like body 2 is further pushed to the card-like body pushing limit position from that state as shown in FIG. 9C, it acts on the card-like body 2 via the interlocking engagement piece 26 and the interlocking engagement portion 22. The pushing force to be transmitted is transmitted to the slider 20, and the slider 20 moves together with the card-like body 2 against the urging force of the pushing spring 25 to the interlocking limit position S 2, and the restriction pin portion 33 returns to the return path portion 50 in conjunction with this. It passes over the inclined portion 60 and the return prevention step portion 56 and falls into the pushing operation allowing portion 52 and slides to the innermost position P2 in the pushing operation allowing portion 52.

  As described above, in the first pushing operation of the card-like body 2, the regulation pin portion 33 is retracted into the pushing-motion allowing portion 52 so as not to prevent the movement of the card-like body 2 and the slider 20.

  Further, since the card-like body 2 is restricted from moving toward the pushing side from the card-like body pushing limit position, the position of the slider 20 at that time becomes an interlocking limit position S2 that can move together with the card-like body 2, and the card-like body Depending on the pushing operation of the body 2, the slider 20 cannot move to the pushing side from the interlocking limit position S2.

  Next, when the force in the pushing direction with respect to the card-like body 2 is removed from the state of FIG. 9C, the slider 20 is urged in the pushing direction by the pushing spring 25, and the urging force acting on the slider 20 is linked. It is transmitted to the card-like body 2 through the coupling piece 26 and the interlocking engagement portion 22 and pushes back the card-like body 2 to a predetermined insertion position shown in FIG. 9D, and the slider 20 is pushed back to the lock position S3.

  In conjunction with the movement of the slider 20, the restricting pin portion 33 moves from the pushing operation allowing portion 52 to the locking guide path 53, is guided by the guiding step portion 61, passes over the return prevention step portion 57, and engages with the heart cam 42. It moves into the position P3 to be engaged, that is, into the engaging recess 44.

  As a result, as shown in FIG. 5, the restricting pin portion 33 engages with the heart cam 42 and the movement of the restricting pin portion 33 in the pushing direction is restricted, so that the slider 20 is moved via the lock pin 28 at the lock position S3. Movement in the extrusion direction is restricted.

  Even in this state, it is possible to push the card-like body 2 to the card-like body pushing limit position, but as described above, the slider 20 can move together with the card-like body 2 only up to the interlocking limit position S2. is there.

  Further, in this state, the restriction pin portion 33 is in the position P3 where the heart cam 42 is engaged, and when the slider 20 moves in the push-in direction, the restriction pin portion 33 slides in the release guide passage portion 54 in conjunction therewith.

  Accordingly, since the release return prevention step portion 58 is formed at a position shifted from the position P4 of the regulation pin portion 33 in the release guide passage portion 54 in the interlocking limit position S2 to the rear side in the slider moving direction, the card-like body. 2, when the pushing force acting on the card-like body 2 is released, the slider 20 is moved by the urging force of the pushing spring 25. It is pushed back to the lock position S3, and the restricting pin portion 33 is also pushed back to the position P3 that engages with the heart cam.

  Therefore, even when a load in the card pushing direction is applied to the card-like body 2 due to the drop of the electronic device or careless contact, depending on the pushing operation of the card-like body 2 again, the slider 20 is pushed in the pushing direction. Since the movement restriction is not released, the card-like body 2 can be prevented from being discharged unexpectedly.

  On the other hand, as shown in FIGS. 10D to 10G, the lock state is released by using the key member 80 to disengage the slider 20 from the card-like body 2 to the pushing-in side, thereby releasing the lock release position S4, That is, it can be performed only by moving the restricting pin portion 33 to a position P5 that reaches the return path portion 51 beyond the release return preventing step portion 58.

  First, as shown in FIG. 10 (d), the pin-shaped key member 80 is inserted into the slider moving portion 14 through the insertion guide hole 79, and the tip of the key member 80 is placed on the front side surface of the pressed piece 24 of the slider 20. Make contact.
