DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a shoplifting prevention apparatus, and more particularly to a self-sounding shoplifting prevention apparatus which can be used in combination with a paper shoplifting prevention apparatus for preventing shoplifting of music CDs, game software, video tapes and the like. About.

[0002]

2. Description of the Related Art To prevent shoplifting of music CDs and the like,
A shoplifting prevention device that detects an unpaid item at an exit gate and sounds a buzzer when a displayed product is taken out of the store as it is is used. As shown in FIG. 6, the customer takes the merchandise with the tag attached to the checkout point, stops or removes the tag function at the time of payment, and takes it out of the store. A gate or tag will alert you if you try to remove an unpaid item.

[0003] Shoplifting prevention devices are broadly classified into two types, a paper type and a self-sounding type. In both cases, radio transmission gates (two transmission / reception pairs for the paper type, one or two transmitters for the self-sounding type) are placed facing each other at the entrance and exit of the store, and the tag-attached products are taken out of the store. . When the tag-attached product is taken out of the store to the entrance and reaches the detection area between the gates, a warning buzzer and a warning lamp are activated and an alarm is issued. However, this does not apply to the case where the tag was removed or the alarm function was canceled at the checkout station. The major difference between the paper type and the self-sounding type is that the alarm is output from the gate in the paper type and is output from the tag in the self-sounding type.

[0004] In the paper type, a paper that absorbs radio waves is attached to a product, and a gate receiver detects that the radio waves emitted from the exit gate are absorbed by a gate receiver and issues an alarm at the gate. It is. 58kHz or 8.2 frequency
The thing using the radio wave of MHz is used. In FIG.
The principle of the paper type (gate alert type) is shown. In the paper type, the transmission gate 16 and the reception gate 17 are provided to face each other, and if a paper type tag 20 that resonates at the transmission frequency enters between them, a change occurs in the reception signal, the alarm buzzer 19 issues an alarm and the alarm lamp 18 turns on. Notifies the unauthorized removal by flashing.

[0005] An advantage of the paper type is that since the tag is inexpensive, investment at the time of introduction can be reduced. As a disadvantage, when a plurality of customers pass through the gate at the same time, it is not possible to identify the carry-out criminal, and it is difficult to collect the carry-out goods. In addition, there are also problems that there are many malfunctions due to noise radio waves from electronic products, that the gate interval is as narrow as 90 cm to 150 cm, and that the tags are easily destroyed.

In the self-sounding type, a product is put in a case in which a receiver and a buzzer are incorporated, and the buzzer sounds when a radio wave from the exit transmission gate is received. 22k frequency
Those using radio waves of Hz or 38 kHz are used. FIG. 8 shows the principle of the self-sounding type (tag alert type).
In the self-sounding type, when the self-sounding tag 2 receives a radio signal transmitted from the transmission gate 21 (one or two), an alarm buzzer and an alarm lamp of the self-sounding tag 2 emit and emit light, respectively. .

The advantages of the self-sounding type are that the gate interval is as wide as 300 to 400 cm when two gates are used, and that malfunctions are small.
In addition, since it is easy to identify the carry-out criminal, the collection rate of the brought-out products is high, and even if the tag is removed,
Since the alarm is issued by the detection switch, the effect is greater than that of the paper type. The disadvantage is that the unit price of the tag is
Because it is about 10 to 100 times, investment at the time of introduction is high.

In the paper-type shoplifting prevention device, a product is put in a case for shoplifting prevention and locked. The product and the tag of the shoplifting prevention device are integrated, and a warning is issued at the exit of the store unless the lock is released at the time of payment. There is no self-sounding shoplifting prevention device having a lock mechanism.

As a lock mechanism of a conventional anti-shoplifting device, there is one disclosed in Japanese Patent Application Laid-Open Nos. 9-328184 and 9-83477. 9 and 10 show examples of a case for preventing shoplifting having such a lock mechanism.
This is a case for paper type anti-shoplifting device,
This prevents the product from being taken out of the case 1 to which the paper tag 20 is attached.

Product 8 such as CD in transparent resin case 1 having the shape shown in FIG.
Is inserted, and the CD or the like is fixed to the case 1 by operating the lock bar 22. When the lock bar 22 is in the open position, a CD or the like can be moved, so that a CD or the like can be freely taken in and out. When the lock bar 22 is in the lock position, the movement of a CD or the like is restricted by the lock bar 22, and is blocked by the four claws 23 on the outer periphery of the case.
Items such as D cannot be taken out.

There are two main types of lock bar operation mechanisms: a type using a mechanical dedicated key and a type using a magnet. A lock mechanism using a magnet will be described with reference to FIGS. As shown in FIG. 11, a U-shaped lock spring 25 and a lock bar 22 having concave portions on both sides of an upper end are provided on a lock case 24 at the end of the case. As shown in FIG. 12, in the locked state, U
The tip of the letter-shaped lock spring 25 is engaged with the concave portion of the lock bar 22 to fix the lock bar 22 so as not to move. FIG. 12A is a side view of the locked state, and FIG.
FIG. 2B is a plan view. In the open state, as shown in FIG. 13, the tip of the U-shaped lock spring 25 is pulled outward by the magnet 26 of the release jig, and comes off the concave portion of the lock bar 22. In this state, the lock bar
The U-shaped lock spring 25 does not return to the recess of the lock bar 22 even if the release jig is removed. FIG. 13A is a side view of the open state,
FIG. 13B is a plan view.

Other known examples of the shoplifting prevention device are disclosed in JP-A-9-115062, JP-A-8-185584, JP-A-7-239983, and JP-A-7-31636. Something was done.
