[Prior Art] In recent years, shoplifting prevention devices that provide a transmitting antenna unit and a receiving antenna unit facing each other and output a notification sound when a product with a check tag attached passes between the antenna units have become popular. ing.

This shoplifting prevention device has an electromagnetic wave modulation circuit when a product with a built-in electromagnetic wave modulation circuit such as a diode circuit or an LC circuit is attached to the product in advance, when the product attached with the check tag passes through this antenna. The transmission radio wave signal is modulated by, the modulated signal is received by the reception antenna unit, and a notification sound or the like is output. As a result, if the check tag is forgotten or the unpaid item is taken out, it can be checked.

[Problems to be solved by the invention] However, the check tag attached to the product cannot be removed unless a special device is used, and it is troublesome to take it out one by one. Further, if the user forgets to remove the product, a notification sound or the like may be output regardless of the product that has been settled, which may cause an unfavorable situation in terms of service.

Furthermore, the check tag may be fixedly adhered and difficult to remove, and in such a case, a special operation must be carried out so that the device does not operate.

Particularly, in a rental video store, a rental video tape is repeatedly used and repeatedly taken out and brought into and out of the store. For this reason, it is not appropriate to attach / peel the check tag to / from the tape hub each time, and it is common to leave it attached. Further, it is very troublesome to stop the operation of the shoplifting prevention device each time it is rented out, and the shoplifting prevention function is completely stopped during the operation stop.

[Means for Solving the Problems] The present invention has been made for the purpose of solving the above problems, and includes the following configuration as one means for solving the above problems.

That is, the case main body portion is formed of a material having radio wave transmission characteristics, and a pocket body portion is provided on the inner wall of the case at a position facing the radio wave modulation means pasting position of the storage item.

Configure to control non-detection.

Alternatively, the stored item in the above configuration is a video cassette tape hub on which video software is recorded, and the case main body is made of a substantially transparent material so that the stored item and the attached tag can be confirmed from the outside.

[Operation] In the above configuration, the electromagnetic wave can be easily shielded only by housing the product etc. to which the radio wave modulating means is mounted in the case body as it is and housing the detection prevention tag in the pocket part of the case body part. be able to. Therefore, it is not necessary to remove the modulation circuit one by one.

Further, it is possible to prevent the reception of the modulation signal due to the passage of the product etc. without stopping the operation of the device.

Furthermore, by making the case transparent, you can easily manage the product by simply reading the product identification tag etc. and storing the detection prevention tag in the pocket section without taking out the video software cassette tape hub from the case. Also, shoplifting prevention can be perfect.

[Embodiment] An embodiment according to the present invention will be described in detail below with reference to the drawings.

The following description will be made with reference to the case where this embodiment is applied to the storage case of the video cassette tape hub of the video rental shop.

FIG. 1 is an exploded perspective view of a storage case of a video cassette tape hub for use with a shoplifting prevention device according to an embodiment of the present invention. Referring to FIG. The manufacturing process and its structure will be described.

This storage case is for storing the video cassette tape hub and is used together with the shoplifting prevention device shown in FIG. The display case is displayed with only the video software cassette tape hub to which a check seal with an LC circuit or a diode circuit, which is an electromagnetic wave modulation circuit, is attached, and it is displayed without removing the check seal when renting. The detection by the modulation signal detection unit 27 can be prevented only by inserting the detection prevention tag into the section and closing the lid.

Guess 2 made of a transparent hard PVC sheet is molded in advance so that it can be housed in a video cassette tape hub as shown in FIG. Similarly, the body lid 3 made of a transparent hard PVC sheet is also formed so that it can be stored in the hub.

These are formed by processing such as cutting a transparent hard PVC sheet, press molding, and punching.

The transparent soft vinyl chloride sheet 1 for the cover and the transparent soft transparent vinyl chloride sheet 4 for the pocket are cut into a predetermined shape.

The transparent soft vinyl chloride sheet 1 for the cover and the transparent soft vinyl chloride sheet 4 for the pocket, which are cut in this manner, are processed together with the gusset 2 and the lid 3 of the cover. Then, the guess 2 and the body lid 3 are welded to the transparent and soft transparent PVC sheet 4 for the pocket and the body lid 3.

FIG. 2 is an external perspective view of the storage case integrally formed in this way.

The sticking position of the check tag to the video software cassette tape hub stored in the storage case 10 in this embodiment is
It is desirable that a metal plate that shields electromagnetic waves, a metal seal, or the like is not provided below or inside the attachment position. This is to prevent the electromagnetic waves that are transmitted by these metal plates and the like from decreasing and the electromagnetic wave modulation by the LC circuit or diode circuit arranged in the check tag from decreasing.

Therefore, a metal leaf spring or the like for pressing the tape is disposed at the center of the hub, which is not desirable.

Therefore, it is naturally desirable that the check tag is attached at any of the positions shown by the diagonal lines in FIG. 3 or the 32 positions shown by the broken line arrows.

Therefore, in the present embodiment, the check tag is attached at a position indicated by hatching in FIG. This diagonal position is
When the cassette tape hub is stored in the storage case 10,
It is a position just below the position of the pocket 4. That is,
The pocket 4 of the storage case 10 is provided at a position that is uniquely determined according to the attachment position of the check tag 31.

However, the check tag attachment position is not limited to the above hatched position, and may be attached at the position indicated by 32. However, in this case, the position where the pocket of the storage case 10 is provided is the position opposite to the position where the check tag is attached.

Next, the structure of the shoplifting prevention device used in this embodiment is shown in FIG. In the figure, reference numeral 21 is a transmitting unit that amplifies a high frequency signal from an oscillator 22 and sends it to a transmitting antenna 23. The high frequency signal from the transmitting unit 21 is radiated from the transmitting antenna 23 into the air as a radio wave signal. This transmission radio signal is received by the reception antenna 25 which is provided facing the transmission antenna 23 with a predetermined distance.
Will be received at. Then, it is amplified and shaped by the receiving unit 26 and sent to the modulated signal detecting unit 27, where it is determined whether or not a signal modulated with respect to the transmitted radio wave signal is received.

Here, if the check tag 31 in which a radio wave modulation circuit such as a diode circuit or an LC circuit is incorporated is attached to the product in advance,
When the product attached with the check tag 31 passes between the antennas, the radio wave modulation circuit of the check tag 31 modulates the transmission radio wave signal, and the modulated signal is received by the reception antenna 25, and the reception section 26 is used. The signal is sent to the modulation signal detector 27. The modulated signal detection unit 27 detects this modulated signal if it is modulated, and outputs the detected signal to the notification sound output unit 28 and the display unit 29. As a result, the alarm sound output unit
An alarm sound is output from 28, and at the same time, the passage of the check tag 31 is displayed on the display unit 29, and it is possible to check out the unpaid item.

Therefore, the rental video software cassette tape hub to which the check tag 31 is attached is stored in the storage case 10 in which nothing is put in the pocket of this embodiment, and is displayed on the rental tape display rack. In this way, since the rental tape hub is displayed while being stored in the case, it is not necessary to provide a special tape storage space. In this state, the check tag is in a detectable state, and when the video software attached with the check tag 31 passes between the transmitting antenna section 23 and the receiving antenna section 25 of the shoplifting prevention device shown in FIG. The signal detection unit 27 detects this, the notification sound output unit 28 outputs the notification sound, and the display unit 29 displays the notification sound.

On the other hand, when the customer brings the storage case 10 to the counter or the like and performs the rental procedure, directly from the top of the storage case,
Alternatively, the lid is opened, and the lending information is input to the POS or the like by a bar code or the like, and the lending certificate described later is put in the pocket section 4 (as indicated by the chain line 8 in FIG. 2) and handed to the customer.

This loan certificate has a thin piece of shield attached to the surface or in the center, can be stored in the pocket portion 4, and is large enough to cover the check tag 31 attached to the cassette hub when stored in the pocket portion 4. It is a thing.

The thin piece for shielding attached to the loan certificate is formed by depositing PET in a thickness of, for example, about 50 μm, but any thin piece can be used as long as it shields electromagnetic waves.

If a shield thin piece is attached to the center of the loan certificate so that it cannot be immediately known from the outside that the shield thin piece is present, the shield thin piece is completely hidden from the surface and is in shoplifting. No structure is known to prevent actuation of the protection device.

At the time of renting, the checkout tag 31 is covered with this checkout card and is electromagnetically shielded because the checkout tag 31 is inserted into the pocket section 4 of the storage case 10 and handed over to the customer. In particular,
When the video software cassette hub is rewound, the tape is at the check tag attachment position shown in 31 of FIG. 3, and the other side is also kept electromagnetically shielded by the action of the tape. It Therefore, even if the storage case passes between the transmitting antenna unit 23 and the receiving antenna unit 25,
The radio waves will not be modulated, and no notification sound will be output.

In this way, by using the storage case of this embodiment,
It is possible to prevent goods with a check tag from being taken out without the operation of the shoplifting prevention device. Also, without the troublesome work such as removing the check tag, you can simply pass the checkout card by inserting it into the pocket section 4 and passing it. The situation of detection can also be prevented.

In the rental video store, the rental video tape is repeatedly used and repeatedly carried out and brought in and out of the store, but when the storage case 10 of the present embodiment is used, the video tape is rented to the customer by the video rental shop. At times, the operation of the shoplifting prevention device can be stopped only by a simple operation of inserting the lending certificate into the pocket portion 4 of the storage case 10. At this time, the shoplifting prevention device is in an operating state, and when a check tag is attached and an item for which a loan certificate is not stored passes through the device, it can be reliably operated.

The above description has been made by taking the video cassette case as an example of the storage case, but the present invention is not limited to the above example, and can be applied to any case as long as it stores a product to be rented by a rental shop. . For example, when a check tag is attached to a compact disk, a pocket part for inserting the loan certificate with the above-mentioned thin sheet for electromagnetic wave shielding is inserted in the compact disk case, and the loan certificate is used at the time of loan. All you have to do is insert it into the section.

When renting a rental product in a storage case like this, insert a sheet with a thin piece of electromagnetic wave shielding into the pocket of the storage case that stores the rental product to shield the check tag of the stored item from electromagnetic waves. You can do it.

As described above, according to the present embodiment, when the shoplifting prevention device is installed, the product attached with the check tag is put in the case of the present embodiment, and the electromagnetic wave is shielded in the storage case pocket part at the completion of the rental procedure. The operation of this device can be prevented even if it is repeatedly passed through this device only by inserting the sheet to which the thin flakes are attached and shielding the check tag of the stored items from electromagnetic waves.

Moreover, by incorporating the electromagnetic wave shielding seal in the central portion of the lending certificate so that it cannot be seen from the outside, it is possible to effectively prevent shoplifting without knowing a mechanism for not operating the shoplifting prevention device.

Furthermore, there is no need to store the product in another place,
Space saving can be achieved, and the detection state of the shoplifting prevention device can be controlled with a simple configuration and work.

[Effects of the Invention] As described above, according to the present invention, it is possible to prevent the operation of the shoplifting prevention device by storing the product etc. in the case and simply inserting the radio wave shielding seal in the pocket part.
It is especially effective in the business of repeatedly lending and returning products such as rental shops.

Furthermore, by making the case transparent, you can easily manage the product by simply reading the product identification tag etc. and storing the detection prevention tag in the pocket section without taking out the video software cassette tape hub from the case. Also, shoplifting prevention can be perfect.
