In addition, the movement of the card-shaped body 2 to the push-in side relative to the card-shaped body push-in limit position is restricted, so the position of the slider 20 at this time is the interlocking limit position S2 that can move together with the card-shaped body 2. The push-in operation of the card-like body 2 prevents the slider 20 from moving to the push-in side relative to the interlocking limit position S2.

Next, after removing the force in the push-in direction of the card-shaped body 2 from the state of FIG. The card-shaped body 2 is transferred to the card-shaped body 2 by the matching piece 26 and the linkage matching portion 22, and the card-shaped body 2 is pushed back to the specified insertion position shown in FIG. 9(d), and the slider 20 is pushed back to the locking position S3.

The restricting pin portion 33 is linked with the movement of the slider 20, moves from the push-in operation permitting portion 52 to the locking guide path portion 53, is guided to the guide step portion 61, passes over the return preventing step portion 57, and moves to a position corresponding to the heart-shaped cam. 42 fits in the position P3, that is, fits in the concave portion 44.

Thus, as shown in FIG. 5 , since the restricting pin portion 33 cooperates with the heart-shaped cam 42, the movement of the restricting pin portion 33 in the push-out direction is restricted, so the lock pin 28 at the locked position S3 makes the sliding block 20 move in the push-out direction. Movement is restricted.

Even in this state, the card-shaped body 2 can be pushed in until the card-shaped body push-in limit position, but as described above, the slider 20 and the card-shaped body 2 can move together before the interlocking limit position S2.

In addition, in this state, when the restricting pin portion 33 is located at the position P3 engaged with the heart-shaped cam 42 and the slider 20 moves in the pushing direction, the restricting pin portion 33 is interlocked with it on the release guide path portion. 54 slides.

Therefore, since the release anti-return step portion 58 is formed at a position staggered inward in the slider moving direction relative to the position P4 of the restriction pin portion 33 in the release guide path portion 54 on the interlocking limit position S2, the card-shaped When the body 2 is pushed in again, the limiting pin portion 33 cannot reach the release prevention step portion 58, and after the pushing force acting on the card-like body 2 is released, the sliding block 20 is pushed back to the position by the force of the release spring 25. At the locked position S3, the restricting pin portion 33 is also pushed back to the position P3 where it cooperates with the heart-shaped cam 42 .

Thus, even if a load in the direction of card insertion is applied to the card-shaped body 2 due to the drop of the electronic device, inadvertent contact, etc., the slider 20 is pushed in again due to the pushing action of the card-shaped body 2 again. The movement restriction in the push-out direction is not released, so that the card-shaped body 2 can be prevented from being unintentionally ejected.

On the other hand, the release of this locked state can only be performed as shown in FIGS. The lock release position S4 is a position P5 where the restriction pin portion 33 moves over the release preventing return step portion 58 to reach the forward path portion 51 .

First, as shown in FIG. 10( d), the pin-shaped wedge member 80 is inserted into the slider moving part 14 through the insertion guide hole 79 so that the front end of the wedge member 80 is close to the pushed-in piece 24 of the slider 20. Side abutment.

Then, further use the wedge member 80 to push the slider 20 from this state, and the card-shaped body 2 moves together, and at the push-in limit position, the inner side edge (blocking portion 75 ) of the card-shaped body 2 is blocked by the protruding portion 74 Blocking, the movement of the card-shaped body 2 in the pushing direction is restricted.

Before the slide block 20 and the card-like body 2 arrive at the interlocking limit position S2, the limiting pin portion 33 is interlocked with it and moves in the guide path portion 54 for release, but can only move to the position P4. After pushing in, the slider 20 is pushed back to the locked position S3 by the force of the push-out spring 25, and the limiting pin 33 is also linked with it, and pushed back to the position P3 matched with the heart-shaped cam.

On the other hand, from the interlocking limit position S2, further using the wedge member 80 to push the slider 20 with a certain force or more, as shown in FIG. The slider 20 is independent and detached from the card body 2 .

Then, when the slider 20 is pushed into the unlocking position S4, the limiting pin portion 33 is linked with it, and goes over the return inclined portion 62 and the release preventing return step portion 58, falls into the return path portion 51, and reaches the slave heart cam 42. The disengaged position P5.

As a result, the restriction on the movement of the slider 20 in the push-out direction is released, and the wedge member 80 is pulled out from the housing 4, and the slider 20 is urged in the push-out direction by the push-out spring 25, and is pushed back to the interlocking limit position S2. .

Then, at the interlocking limit position S2, the proximate side edges of the cooperating piece 26 and the interlocking coordinating portion 22 abut against the inner side edge of the card A and the proximate side inner edge of the notch respectively for interlocking, from this state as shown in FIG. As shown in 10(g), the slider 20 returns to the original position S1 while pushing out the card-shaped body 2, and accordingly, the restricting pin portion 33 also returns to the original position P1, and the card-shaped body 2 is pushed by the slider 20 and released from the housing. Body 4 is discharged.

Moreover, in the above-described embodiment, it is aimed at using the inner side of the card-shaped body 2 as the blocking portion 75 at the push-in limit position of the card-shaped body 2 and is blocked by the blocking protrusion 74 arranged in the inner part of the housing 4. The example has been described, and it is also possible to form the blocking portion 75 at the front edge cover body 71 of the card-like body 2 and set the blocking protrusion 74 on the frame of the electronic device carrying the connector, so that the blocking protrusion 74 formed on the electronic device frame can The blocking portion 75 is blocked by the blocking portion 74 to restrict movement to the push-in side relative to the push-in limit position of the card-shaped body.

In addition, in the above-mentioned embodiment, the example in which the card-like body 2 is used as the card tray has been described, but the card-like body 2 may be an IC card, a flash memory card or the like itself.

In addition, in the above-mentioned embodiment, the example in which the heart-shaped cam portion 40 is provided on the molded body 10 (housing 4) has been described, but the slider 20 may also be formed of an insulating synthetic resin, and the slider 20 may be A heart-shaped cam portion 40 is provided so that one end of the lock pin 28 is rotatably supported on the housing 4 .

Furthermore, the shapes and orientations of the heart-shaped cam 42 and the pin guide groove 41 are not limited to the above-mentioned embodiments, and are determined by the positional relationship of the locking pin 28 , the slider 20 , the heart-shaped cam portion 40 and the housing 4 .

In addition, the case 4 may be provided with a take-out operation detection switch composed of an operation-side switch contact and an operated-side switch contact in addition to the detection switch 78 .

In this case, it is preferable that the take-out operation detection switch is turned ON by contacting the operating side switch contact with the slider 20 at the lock release position S4, whereby the operating side switch contact is brought into contact with or separated from the operated side switch contact. /OFF state switching.
