Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an article monitoring apparatus for storing goods in a clear case to prevent shoplifting of goods in a CD shop or the like, and more particularly to a clear case and a method of manufacturing the clear case.

[0002]

2. Description of the Related Art Conventionally, as this kind of article monitoring apparatus,
2. Description of the Related Art A passive paper tag having no power supply therein is known. This paper tag is attached to the product, and if you try to take out the product without permission, it will react when you pass the side of the transmitting device installed at the entrance of the store etc., and the alarm provided on the transmitting device will sound and the theft will be stolen Prevention.

[0003] However, although this paper tag is inexpensive, the alarm sounds at the gate, and when multiple people pass at the same time, it is not possible to know which person is trying to illegally take out the product, so that the site There is a drawback that is difficult to hold down. In addition, there is also a disadvantage that a criminal trying to forcibly pass through the gate cannot determine the point at which a warning is to be transmitted, so that he can escape with a delay.

A self-sounding article monitoring device which has a power supply inside, receives radio waves from a transmitter at the entrance, and emits an alarm by itself is known as a device which solves this drawback.
This self-sounding article monitoring device is, for example, a CD shown in FIG.
As shown in FIG. 1, a transparent case (clear case) 41 made of a synthetic resin, an alarm operation detection switch 44 and a buzzer 47 are provided, and a product (cassette containing a compact disc) 48 is stored in the clear case 41. The operation of the buzzer 47 is controlled by the wireless reception circuit 45 and the detection switch 44, and the power supply is turned on.
When the cassette 48 does not exist in the apparatus 1, or when the self-sounding article monitoring device passes through the gate, the sound is emitted.

FIG. 13 shows a state in which goods are stored. At the store, the cassette 48 containing the CD is housed in the clear case 41 of the self-sounding article monitoring device and displayed, and the clerk sets the buzzer 47 so as not to sound when selling the compact disc to the customer. The user removes the cassette 48 from the clear case 41 and hands the compact disc to the customer in exchange for a fee. The self-sounding article monitoring device from which the cassette 48 has been taken out is repeatedly used.

In the above-mentioned self-sounding article monitoring apparatus, when the customer takes out the cassette 48 from the clear case 41 of the self-sounding article monitoring apparatus, the alarm operation detection switch 44 determines that the cassette 48 does not exist in the clear case 41. Is detected and a sounding command is issued to the buzzer 47, and the buzzer 47 sounds in response to the sounding command. Thus, the clerk can know that the cassette 48 has been illegally removed from the clear case 41.

If the customer tries to take the cassette 48 out of the store without permission with the cassette 48 accommodated in the clear case 41 of the self-sounding article monitoring device, a wireless receiving circuit 45 of the self-sounding article monitoring device is provided at an entrance gate or the like. The buzzer 47 issues a sound command to the buzzer 47 in response to the signal from the transmitting circuit, and the buzzer 47 sounds in response to the sound command. This allows the clerk to know that the compact disc is being illegally taken out of the store.

The self-sounding article monitoring device makes it easier to identify the culprit because the product to be taken out rings, and is more effective than the passive paper tag in holding down the site. However, while a paper tag costs 10 to 20 yen, a self-sounding tag is expensive at 200 to 300 yen, so that it is difficult to use many of them.

As a paper tag, a tag on which a tuning circuit made of LC is printed on paper on which a barcode is printed is generally used. For example, a frequency of 8.2 MHz is used. 8.2 MHz is a frequency suitable for producing the LC in a size of 2 to 3 cm in length and width. In addition, 58 kh
Paper tags used in z are also widespread. 58 kh
If the above-mentioned LC circuit is made at z, it becomes too large to be practical, and this 58 kHz paper tag uses a special capacitor. Generally 58kHz low frequency
Although z has better performance, 8.2 MHz is lower in cost because the above-mentioned general-purpose LC circuit can be used.

The self-sounding tag is currently 22 kHz, 3
7.5 kHz and 31.5 kHz are known.
If the self-sounding tag uses the same frequency as the frequency of use of the passive paper tag, the transmitting device for the paper tag can be used as it is, and both can be used in the already popular passive paper tag system. It can be used together. In other words, the expensive self-sounding tag can be considerably tamper-proof by mixing only about one out of every ten in a sampling manner. If the frequency is shared with the passive paper tag, it can be used at the entrance, etc. Since the installed transmitting device can be shared, it is easier to spread. Therefore, it is preferable that the self-sounding tag is designed at a frequency of 58 kHz or 8.2 MHz, which is the most widely used frequency of the paper tag.

FIG. 7 is an overall view of the conventional self-sounding article monitoring apparatus. In FIG. 7A, reference numeral 41 denotes a clear case, which is made of transparent plastic and stores a CD or the like therein and is arranged as a product in the store. 42 in FIG.

[0028]

FIG. 1 is an overall view of a clear case used in a self-sounding article monitoring apparatus according to the present invention.

In FIG. 1, 1 is a clear case,
It is made of transparent plastic, and stores CDs and other items inside it and arranges them as products in the store. In FIG. 1, reference numeral 2 denotes a tag (tag / case) accommodating the article monitoring device, reference numeral 3 denotes a tag mounting opening, reference numeral 4 denotes a retaining claw, reference numeral 5 denotes a top cover for retaining the same, and reference numeral 6 denotes a case take-out and carrying case. 7 is a punching hole provided on the back surface of the case, and 8 is a sound emission port. A CD or the like is stored with its vertical direction aligned with the vertical direction in FIG. In other words, the vertical and horizontal dimensions of the clear case are designed so that a CD or the like can be stored with the vertical direction of the clear case aligned with the vertical direction of FIG.
(Hereinafter, this type is referred to as a horizontal clear case, and the conventional type is referred to as a vertical clear case.) In this embodiment, the article monitoring device operates at 8.2 MHz.

The clear case shown in FIG. 1 has a height (vertical dimension) of 14 cm or less. This means that only spines that are popular in the market are displayed on the front side and displayed side by side (hereinafter,
It is called horizontal display. ) Dimensions that can be stored in a cabinet for horizontal display.

FIGS. 2A and 2B are a top view and a side view of the clear case, and FIG. 3 is a rear view of the clear case. In the figure, reference numeral 2 denotes a tag, 3 denotes a tag mounting opening of the clear case 1, 4 denotes a retaining claw provided on an opening surface so that the CD or the like cannot be taken out when the CD or the like is stored and locked. Is also C in cooperation with the nail 4
D is a cover for the upper surface of the clear case 1 so that the D or the like cannot be taken out, 6 is a supporting hole for holding the clear case with a finger in a state where a CD or the like is stored, and 7 is a retaining claw 4 of the clear case. Die-cut holes 9 provided on the corresponding back side are portions where the die-cut holes on the back surface corresponding to the upper surface cover portion 5 are covered by welding an opaque plate material.

As shown in FIG. 1, the clear case 1 has a box shape having an open top surface composed of a transparent bottom portion 11 and side portions 10, and is formed by pouring a transparent thermoplastic resin into a mold. . Die-cut holes 7 on the back surface and die-cut holes on the back surface corresponding to the top cover 5 are provided for removal from the mold at the time of molding the case. The punched holes on the back surface corresponding to the top cover 5 are filled with an opaque plate material 9 afterwards. In addition, a sheet material after molding can be attached to the back side of the tag attachment port for the same reason. Note that the vicinity of the tag mounting opening 3 and the upper surface cover 5 of the clear case 1 is opaquely processed (for example, grained) so that the inside of the upper surface and the rear surface cannot be seen.

FIG. 4 is an enlarged perspective view of the tag (tag case), FIG. 5 is an enlarged view of a portion A in FIG. 2B, and FIG. FIG. 5B shows a top view in an attached state, FIG. 5B shows a side view, and FIG. 5C shows a bottom view in which only unnecessary parts are removed.

The tag shown in FIG. 4 is inserted into the tag mounting opening with the upper left side of the figure as a head. The tag has a lock groove 2
5, 26 and locking projections 21 and 22 are provided, and the upper part of the projections 21 and 22 is a slip slope. Its structure is the same as that shown in FIG. 14 in detail. The tags 23 and 24 are guides for insertion into the mounting opening 3 and are formed in a rib shape so as to form an opening 32 into which a claw of a tag stopper enters as shown in FIG. It is. In the case of the tag receiving port 27, FIG.
As can be seen in FIG.
(Dotted line in the figure) is attached. The locking operation by the lock spring is the same as that described in detail in the description of FIG.

In the present invention, the lock spring 30
Has an opening 31 on the side as shown in FIG. The opening 31 has a function of reducing the elastic force of the spring and improving the operation sensitivity of the magnet. In the case of the conventional vertical clear case, since the width is sufficiently long, the tag case may be long, and the lock spring can be mounted with a sufficiently long one. However, in the horizontal clear case of the present invention, the width of the tag mounting opening is short, and thus the length of the tag case is limited. When the space required for other parts is taken up within the limited length, the length usable for the spring becomes short, and when the same plate-like spring material as in the past is used as it is, the elastic force of the spring is reduced. Is too strong to be released with the releaser magnet.

The opening 3 of the lock spring of the present invention
No. 1 is a contrivance for weakening the elastic force and increasing the operation sensitivity of the releaser to the magnet. Further, in the lock spring of the present invention, the root portion 33 is fixed by a plastic spring suppressing projection 29 (FIG. 5A). This is because if the root portion is free, the lock spring can play inside the mounting opening and cause malfunction.

[0037]

As described above, the clear case used for the self-sounding type article monitoring apparatus of the present invention can be stored and displayed in a cabinet for horizontal display, unlike the conventional case.

Further, by providing an opening in the lock spring, the locking operation is ensured even within the width of the tag mounting opening of the case. In addition, since a hole for punching is provided on the back surface, the chest case body can be manufactured at low cost, and the vicinity of the tag mounting port is made opaque, so that the internal structure is not visible.

The self-sounding article monitoring apparatus using the clear case of the present invention operates at the same frequency as that of the conventional paper tag. If you use the clear case, you can use the cabinets that are conventionally installed as a number of horizontal display shelves as they are, so that the effects of the above-mentioned combined use of the cabinets are synergistic, making it very easy to use and welcome to store users. It has a remarkable effect.
