Is held and retained.

The relationship between the locking pin 27 and the locking portion 35 of the elastic member 33 will be described in more detail. First, an elastic member has a shape as shown in FIGS. 3, 4 and 5, and a metal plate is bent into a substantially triangular shape, and one end side 33a is connected to the other. It is configured to cover the end side 33b. As shown in FIG. 4, the other end 33b is cut away, and the locking portion 35 described above is formed therein. The stepped portion 27a of the locking pin 27 engages with the locking portion 35. Further, the locking pin 27 is constantly urged in the pulling-out direction by the coil spring 28, whereby the stepped portion 27a of the locking pin 27 is securely engaged with and held by the locking portion 35, and the insertion hole is formed. The lock state is established in which the detachment from the position 31 is prevented.

The release device 50 is used to release the locked state of the cord body 21 of the self-sounding security tag, that is, to pull out the locking pin 27 from the inside of the insertion hole 31. That is, a release pin 51 is attached to the release device 50 as shown by a virtual line in FIG. 1, and the release pin 51 is inserted into an insertion hole 53 formed in the lower case 1 and the upper case 3. This allows the locking pin 27 to be pulled out of the insertion hole 31.

That is, when the release pin 51 is inserted into the insertion hole 53, the release pin 51 causes the above-described one end 33a of the elastic member 33 to move as shown by a virtual line in FIG.
It is biased to the left. Due to the displacement of the one end side 33a,
The other end 33b is also displaced in the same direction, whereby the locking portion 35 of the elastic member 33 comes off the stepped portion 27a of the locking pin 27. This allows the locking pin 27 to be pulled out of the insertion hole 31. The case where the locking pin 27 is pulled out from the insertion hole 31 is, for example, such as removing a self-sounding security tag when selling a product, or replacing the self-sounding security tag once attached with another product. Is the case.

The elastic member 33 is formed with a bending piece 55 for operating the release operation start detection switch 15, and the intermediate wall 33c functions as an acoustic wall forming a resonance chamber. It has become.

Next, the structure of the release unit 50 will be described with reference to FIGS.
This will be described in detail with reference to FIG. In FIG. 6, the self-sounding security tag described above is shown left and right reversed. First,
There are a lower case 61 and an upper case 63, and these lower cases 6
An insert base 65 is disposed in a space formed by the upper case 1 and the upper case 63 and at an upper portion thereof. An insert case 67 is accommodated in the insert base 65 so as to be movable in the vertical direction in the figure. A pair of coil springs 69 and 71 are provided between the insert case 67 and the insert base 65.
9 and 71, it is always urged upward.

The upper insert case 67 has a shape matching the shape of the self-sounding security tag described above, and includes a recess 67a into which the shape of the lower half of the self-sounding security tag is inserted. I have. On the insert base 65 side and the coil spring 69 side, the release pin 51 described above is provided to project upward.

As shown in FIG. 7, an alarm output stop switch 70 projects from the back side of the insert base 65. That is, when the self-sounding security tag is inserted into the insert case 67 and urged downward, the alarm output stop switch 70 is pressed and urged by the insert case 67 moving downward. By actuation, thereby the transmitting coil 72
Outputs a signal to the self-sounding security tag to stop the alarm output function.

As shown in FIG. 7, batteries 73 and 75 are accommodated and arranged in the lower case 61 and the upper case 63, respectively. As shown in FIG. 6, an alarm release switch 77 is disposed on the side of the lower case 61 and the upper case 63. The alarm cancel switch 77 is for canceling an alarm when the alarm is currently output.
By pressing / operating, the transmitting coil 71 outputs an alarm release signal. This alarm release signal is received by the receiving coil 9 on the self-sounding security tag side, whereby
The sounding of the buzzer 7 via the CPU 10 is stopped.

The operation will be described based on the above configuration. First, the string body 21 is hooked on an arbitrary product in a state where the action part 29 at the other end of the string body 21 is inserted into and attached to 45 of the lower case 1 and the upper case 3. Then, the locking pin 27 at one end of the cord body 21 is inserted into the insertion hole 3 of the lower case 1 and the upper case 3.
Insert into 1. Thereby, the stepped portion 27 a of the locking pin 27 is engaged with and held by the locking portion 35 of the elastic member 33,
The locking state is established in which the locking pin 27 is prevented from falling out of the insertion hole 31. This completes the attachment of the self-sounding security tag to the product.

Next, a case will be described in which the locking pin 27 is pulled out from the inside of the insertion hole 31 using a release device and is replaced with another product. First, as shown in FIG. 6, the self-sounding security tag is attached to the recess 67a of the insert case 67 of the releaser 50.
Insert inside. Then, the insert case 67 is urged downward against the urging force of the coil springs 69 and 71. By the downward movement of the insert case 67,
First, the alarm output stop switch 70 is pressed and urged to operate. As a result, an alarm output stop signal is output from the transmitting coil 71. The alarm output stop signal is received by the receiving coil 9 of the self-sounding security tag, and the alarm output function is stopped via the CPU 10.

When the insert case 67 is further urged downward after the alarm output function of the self-sounding security tag is stopped, the release pin 51 is inserted into the insertion hole 53 on the self-sounding security tag side. Due to the insertion of the release pin 51 into the insertion hole 53, the one end 33a of the elastic member 33 is displaced as shown by a virtual line in FIG. Due to the displacement of the one end side 33a,
The action piece 55 is also displaced, and the release operation start detection switch 15
Activate

The release operation start detection switch 15 is
If a third party tries to remove the locking pin 27 using an unauthorized jig or the like instead of an authorized releaser,
This is to detect this in advance (before the locking pin 27 is actually removed) and sound the buzzer 7. On the other hand, when using a proper unlocking device, the self-sounding security tag is attached to the recess 67 of the insert case 67 of the unlocking device 50.
The alarm stop switch 70 arranged in the canceller 50 is activated by inserting the self-sounding security tag into the self-sounding security tag, so that the release operation start detection switch 15 is temporarily activated. However, the buzzer 7 does not sound. Therefore, in this case, that is, in the case where the locking pin 27 is removed by a proper release device in order to replace the self-sounding security tag with another product, no alarm is output.

Now, due to the displacement of the one end 33a of the elastic member 33, the other end 33b is also displaced as shown by a virtual line in FIG. The locking portion 3 is moved by the displacement of the other end 33b.
5 is also displaced, whereby the locking pin 27 of the locking portion 35
Is also disengaged from the stepped portion 27a. Therefore, the locking pin 27 can be pulled out from the insertion hole 31.
When the locking pin 27 is pulled out from the insertion hole 31, it is hooked on another product and inserted into the insertion hole 31 again. This completes the replacement of the self-sounding security tag with another product.

Next, the case of theft occurrence will be described.
First, a description will be given of a case where the product is to be stolen while the self-sounding security tag is attached to the product. In this case, the vehicle passes through the doorway of the store, but an antenna (not shown) is provided therein, and the alarm command signal is constantly output from the antenna. Therefore, the receiving coil 9 of the self-sounding security tag receives the alarm command signal,
The buzzer 7 sounds via the PU 10. Thus, the occurrence of the theft is notified.

Next, a case in which the self-sounding security tag is removed from the product and the product is to be stolen will be described. In this case, first, it is conceivable that the string body 21 is cut or broken to remove the self-sounding security tag from the product. When the cord body 21 is cut, one end of the wire 23 is urged by the coil spring 43 toward the alarm switch 13. Then, when the action body 37 presses and urges the alarm issuing switch 13, the alarm issuing switch 13 is activated, and the buzzer 7 sounds via the CPU 10. Thus, the occurrence of the theft is notified.

Next, it is conceivable to try to pull out the locking pin 27 from the insertion hole 31 by using a jig instead of a proper release device. In this case, when the jig is inserted into the insertion hole 53, the one end 33a of the elastic member 33 is displaced as shown by a virtual line in FIG. The switch 15 is operated. In this case, the alarm output stop switch 70 is not operated, and the alarm stop signal is not output.
Via 0, the buzzer 7 sounds. Thus, it is possible to detect that an unauthorized release operation is about to be performed.

According to the present embodiment, the following effects can be obtained. First, in the self-sounding security tag of the present embodiment, the lower case 1 and the upper case 3 are formed in a substantially square shape in consideration of a design point.
The vertical direction is set in a direction along the diagonal line. Therefore, the length in the up-down direction is shortened, and it is difficult to secure a stroke at the time of insertion into the release device 50 as it is. However, the insert case 67 is arranged on the canceller 50 side, and the alarm output stop switch 69 is quickly activated when the self-sounding security tag is inserted. In other words, the shortened stroke can be supplemented by the arrangement of the insert case 67, so that the operation of the alarm output stop switch 69 and the subsequent unlocking operation by inserting the release pin 51 into the insertion hole 53 are excellent. It is something that can be performed with a good timing. Therefore, the stop of the alarm output and the unlocking operation are executed at the very close timing, thereby eliminating a malfunction. Further, since the insert case 67 is provided with the concave portion 67a having a shape matching the shape of the self-sounding security tag, the insertion operation of the self-sounding security tag can be performed smoothly, and the insertion workability can be improved. Things. In particular, in the case of applying to a self-sounding security tag having a configuration in which the side surface of the case is not a side surface shape, if the release device 50 attempts to release the self-sounding security tag when there is no insert case 67, the self-sounding security tag will The release operation is difficult because there is no flat surface on the side as a reference for sliding on the release pin 51 or the like. However, the presence of the insert case 67 allows the self-sounding security tag to be always inserted in the same state. It can improve the performance.

The present invention is not limited to the above embodiment. First, in the case of the embodiment,
The self-sounding security tag having a substantially square shape has been described as an example of the unlocking device, but the invention is not limited thereto. The present invention is similarly applicable to security tags having various other shapes.

[0035]

As described above in detail, according to the security tag remover according to the present invention, first, the security tag is formed into a shape whose length in the vertical direction is reduced in consideration of the design. On the release unit side, the insert case is arranged to replenish the shortened stroke, so that, for example, the operation of the alarm output stop switch and the subsequent unlock operation can be executed with good timing. . Also, when the insert case is formed with a recess having a shape that matches the shape of the self-sounding security tag, the insertion operation of the self-sounding security tag is performed smoothly, and the insertion workability is improved. Can be done.
