[0012]
BEST MODE FOR CARRYING OUT THE INVENTION
Next, a preferred embodiment of the present invention will be described with reference to the drawings. FIG. 1 is a perspective view showing an opened state of a security tag embodying the present invention, FIG. 2 is a front view of the same wireless IC chip, FIG. 3 is a front view of the same security tag manufacturing process, and FIG. , FIG. 5 is a perspective view of the same case tag, FIG. 6 is an enlarged view showing the twisting of the metal wire in the string portion, FIG. 7 is a perspective view showing a part of the wound state, and FIG. It is a perspective view showing other examples.
[0013]
In these figures, reference numeral 1 denotes a security tag body embodying the present invention. The security tag body 1 is used in a state of being formed from paper or a plastic film, folded in two, and adhered to the inner surface thereof, and inserted through a thread or a fastener for hanging the product as necessary. Hole 15 can also be drilled.
[0014]
A foil layer 2 made of a soft magnetic material is provided on a part of the inner surface of the security tag main body 1, in the present embodiment, at a position near the outer end on one side to be folded in two. The soft magnetic material foil layer 2 is not particularly limited in crystal structure or alloy composition as long as it is a metallic magnetic material showing soft magnetism, but has a permeability of 5 mOe and an excitation magnetic field of 1 kHz from the correspondence with a security gate sensitive to magnetism. Having a high magnetic permeability of 1,000 or more is preferred.
[0015]
From this point, permalloy, Fe-Si alloy, amorphous metal and the like can be used as the soft magnetic material foil layer 2, but in the present embodiment, Co-Fe-Si-B, which exhibits particularly high magnetic permeability, is mainly used. Amorphous metal is employed.
[0016]
Further, the foil layer 2 in the present embodiment is laminated with a nickel foil (foil) as a semi-hard magnetic material in order to deactivate the magnetic characteristics of the amorphous metal. The foil layer 2 is formed by turning on a two-pole power source in a low-pressure container and sputtering the molecules from minus to plus.
[0017]
The security tag body 1 of such a form can be obtained as shown in FIGS. A paper sheet or a film serving as the security tag main body 1 is laminated on a long base sheet 3 to be rolled in a releasable manner, and the above-described foil layer is provided substantially at the center of the paper sheet or the film laminated on the base sheet 3. 2 is formed continuously, and is cut along the cut line 4 in the longitudinal direction to form a product in which the security tag main body 1 is peelably laminated, that is, in the longitudinal direction of the base sheet 3. A product in which the two security tag bodies 1 are laminated so as to face each other simultaneously is obtained. Needless to say, the adhesive 5 is interposed between the security tag body 1 and the base sheet 3.
[0018]
Further, on the inner surface of the security tag main body 1, a chip pack 6a containing a wireless IC chip 6 displaced from the foil layer 2 described above is provided by sticking or holding the security tag main body 1 by two-folding. If necessary, the security tag body 1 can be stored in a PVC bag or the like.
[0019]
This is the wireless IC chip 6 be in a chip pack 6a is connected an antenna unit 6b for winding the near periphery of the chip pack 6a is also made possible to cope with radio waves of about 0.1 to 10 3 ^m ing. This has been made possible by the relaxation of the revision of the Radio Law in FY2002.
[0020]
The wireless IC chip 6 can store information of a product to which the security tag main body 1 is attached. In the case of a jewelry item in particular, a case for storing the jewelry item is placed on a negotiation tray (a plurality of items). By displaying the product information on the monitor screen, smooth business negotiations can be performed. For products in the showcase etc., the information is read by the hand scanner, and the information can be displayed on the monitor screen in the same manner as described above. It is possible.
[0021]
On the other hand, in the process of manufacturing the security tag main body 1 shown in FIGS. 3 and 4, the display 7 of the price and the like and the barcode 8 are printed on the surface of the security tag main body 1 if necessary. When printing the bar code 8, if the metal of the soft magnetic material described above is powdered and blended with the ink, it can be made to correspond to a magnetically responsive gate. It is possible to put it.
[0022]
5 to 8 show another embodiment, in which a known case tag 9 is employed in appearance, and the price and brand can be displayed on the surface of the case tag 9 or separately. It can be used by attaching a prepared tag.
[0023]
This case tag 9 has a built-in wireless IC chip similar to that described above, and is provided with a cord 10 for hanging it on a product. At the tip of the cord body 10, there is provided an insertion locking portion 12 which is locked by being inserted into the receiving hole 11, and the insertion locking portion 12 is formed of a conductive metal, It is electrically connected to the internal wireless IC chip.
[0024]
Further, the above-mentioned cord body 10 is twisted with the above-mentioned wire rod 13 obtained by slitting the above-mentioned amorphous metal, and is supposed to function as an antenna corresponding to a radio wave as well as a magnetically responsive security gate. However, in order to obtain a large effect of the antenna, the surface of the amorphous metal wire 13 can be increased to incorporate the fiber into the raw material of the cord 10.
[0025]
Further, in addition to the above-described example, the copper wire 14 can be wound around the surface of the cord body 10 in a coil shape, so that the antenna effect is further increased and the cord body 10 itself has a spring property. It can be held and uniformity in the suspended state of the product can be maintained. In this case, the cord 10 may be a single wire without twist as the core wire 10a.
[0026]
The security tag according to the present embodiment is configured as described above. Here, the wireless IC chip 6 can erase and rewrite information so that it can be recycled even after the sale of the product.
[0027]
【The invention's effect】
The security tag according to the present invention is configured as described above. Therefore, thorough prevention of theft can be achieved by using radio waves in addition to magnetism. In addition, by storing the product information in the tag with the wireless IC chip, it is possible to manage the product in a wide range, including negotiations, as a simple operation without any trouble.
