Abstract

PURPOSE:To provide the identification seal structure which is high in identifying performance of an object to make forgery difficult and decreases illicit action of replacing by a regular identification seal. CONSTITUTION:The identification seal 2 to be stuck on the object has a light reflecting layer 10 provided with a light reflecting surface having characteristic diffraction characteristics which can be identified by an optical identifying means and when the seal is stuck on the object and then peeled off, the light reflecting layer 10 deforms plastically to vary in the diffraction characteristics, so it is difficult to forge the identification seal 2 as to the cost and printing technique, namely, it is difficult to forge the object. Consequently, when the identification seal stuck on the regular object is peeled off and restuck on a forged body, the diffraction characteristics vary without any large variation in the outward appearance, so the illegal act by the resticking can be accused of without making the person who takes the illegal act notice that. Consequently, the forging preventive effect is improved and the illegal act by the resticking of the regular identification seal is reducible.

[Detailed description of the invention]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an identification seal structure for distinguishing between a plurality of objects and identifying that the objects are legitimate objects.

0002

[Prior Art] Traditionally, for example, a registered trademark has been printed on the corresponding product, and a sticker with the trademark printed on the product has been pasted on the product for sale, but the distribution mechanism has become more complex. As a result, counterfeit products other than genuine products were occasionally delivered to sellers from manufacturers other than the official manufacturer. Seller identifies whether the product is genuine or not based on the trademark displayed on the product, but if the above-mentioned trademark is imitated and displayed on the counterfeit product, the seller will be able to determine whether the product is genuine or not. could not be identified. Another idea is to place a barcode on the surface of the product and use this barcode to identify whether it is a genuine product, but since the barcode itself is easy to imitate, it is difficult to identify whether the product is genuine or not. I can't wait.

[0003] On the other hand, it has traditionally been important to prevent counterfeiting of various securities and tickets, etc., and it is made difficult to counterfeit by applying markings, multi-color printing, etc. to the objects. This also made it easier to identify them as counterfeits.

However, with the recent development of paper processing technology and printing technology, it has become possible to imitate the above-mentioned identification structure relatively easily and inexpensively in the pasting and multicolor printing. In addition, even if the object is marked with sukiiri or multicolor printing, it is conventionally identified by visual inspection, so if the difference between the genuine object and the counterfeit is small, there is a problem that the identifiability decreases. Ta. This decrease becomes especially noticeable when the design of the object changes.

[0005] Therefore, a structure has been proposed in which a hologram, which is difficult to forge, is attached to an object as an identification sticker. In addition, Japanese Utility Model Application Publication No. 61-182580 discloses that by pasting a sticker with a hologram formed on a brittle base material on a target object, when an attempt is made to peel it off after pasting, the hologram is torn together with the brittle base material. A structure has been disclosed that prevents the sticker from being replaced with a counterfeit one.

[0006] However, simply by preventing the replacement of holograms, it is not possible to prosecute those who attempt forgery, and it has not been possible to fundamentally reduce fraudulent acts caused by replacement of holograms.

[0007]

[Problems to be Solved by the Invention] In view of the problems of the prior art, the main object of the present invention is to provide an object that is highly distinguishable, difficult to counterfeit, and has a genuine identification sticker affixed to it. An object of the present invention is to provide an identification seal structure that can fundamentally reduce fraudulent acts caused by changing the identification seal.

[0008]

[Means for Solving the Problems] According to the present invention, such an object is an identification sticker that is attached to an object in order to identify the object, which has an optical identification means on the surface of the identification sticker. A light-reflecting layer that is provided with a light-reflecting surface having unique diffraction characteristics and is easily deformed plastically; a cushion layer that integrally holds the light-reflecting layer and is easily deformed; and the identification sticker is adhered to the object. the cushion layer is elastically or plastically deformed by peeling off the identification sticker, and the adhesive layer has an adhesive force that causes the light reflection layer to be plastically deformed, and the adhesive layer and/or an identification seal structure characterized by adhering to the adhesive layer, or an identification seal affixed to an object to identify the object, which has a unique identification mark on its surface that can be identified by an optical identification means. a light-reflecting layer that is provided with a light-reflecting surface having diffraction properties and is easily plastically deformable; a cushion layer that integrally holds the light-reflecting layer and is easily deformable; The adhesive layer is attached to the object, and the other side is attached to the object.
The cushion layer has a strong base material layer that is bonded with a second adhesive layer having a larger adhesive force than the second adhesive layer, and when the identification sticker is peeled off, the cushion layer is elastically deformed or plastically deformed. This is achieved by providing an identification seal structure characterized in that the first adhesive layer adheres to the base material layer and/or the cushion layer with an adhesive force that deforms and plastically deforms the light reflective layer. be done.

[0009]

[Function] In this way, the identification sticker has a light reflecting layer on its surface that is provided with a light reflecting surface that has a unique diffraction characteristic that can be identified by optical identification means, and when it is peeled off after being affixed to the object, it By plastically deforming the light-reflecting layer and changing its diffraction characteristics, if this identification sticker is affixed to the object, counterfeiting the identification sticker will be difficult both in terms of cost and printing technology. Not only is it difficult to counterfeit objects to which this identification sticker has been affixed, but when the genuine identification sticker is removed from the genuine object and replaced with a counterfeit one, there is no major change in appearance and the diffraction properties Since this changes, it is also possible to accuse fraudsters of changing the stickers without the person trying to commit fraud noticing. Further, by providing a base material layer with high strength, the handling property when attaching an identification sticker to an object is improved.

DESCRIPTION OF THE PREFERRED EMBODIMENTS Preferred embodiments of the present invention will now be described in detail with reference to the accompanying drawings.

FIGS. 1 to 6 show a first embodiment in which the present invention is applied to securities. As shown in FIG. 1, an identification sticker 2 is affixed to the security 1. The identification sticker 2 is provided with a hologram 2a as a light reflecting surface having unique diffraction characteristics, which will be described later.

On the other hand, the identification structure 3 for identifying that the security 1 is a genuine security is connected to a hand scanner 4 and is connected to the hand scanner 4 and is composed of a known CPU, memory, I/F, etc. It has an identification unit 5 for identifying whether or not the issued securities 1 are genuine securities.

A light emitting element 6 is provided in the hand scanner 4 as a means for irradiating illumination light consisting of a laser beam toward the identification seal 2 on the security 1 (FIG. 2). This light emitting element 6 is designed to be able to directly face the identification sticker 2. Further, an annular light receiving element 8 is provided integrally with the light emitting element 6 so as to surround the light emitting element 6 (FIG. 3). This light receiving element 8 has eight parts 8a each capable of receiving light separately.
It consists of a multi-segmented photodiode divided into ~8h in the radial direction. This light receiving element 8 is connected to the identification unit 5.

The hologram 2a of the identification sticker 2 diffracts light from the direction directly facing the hologram, and each part 8a to
It has a diffraction characteristic of being reflected towards any two symmetrical parts sandwiching the light emitting element 6 between the light emitting elements 6 and 8h.

As clearly shown in FIG. 4, the identification sticker 2 is
A hologram reflection layer 10 as a light reflection layer formed by vapor-depositing an aluminum material onto a resin material that is easily plastically deformable and is covered with a transparent protective layer 9 and has a hologram 2a on its surface, and this hologram reflection layer 10 is integrated. a cushion layer 11 made of an elastomer material etc. that is held in place;
1 with the first adhesive layer 12 and bonding the security 1 with the first adhesive layer 12.
It has a relatively hard and high-strength base material layer 13 that is adhered to with a second adhesive layer 14 having a stronger adhesive force than the first adhesive layer 12.

Here, the first adhesive layer 12, that is, the cushion layer 11 and the base material layer 13, can be applied to a force within a range where the cushion layer 11 is elastically deformed and a range where the hologram reflective layer 10 is plastically deformed. It has an adhesive strength that allows it to be peeled off by peeling it off.

Furthermore, since the base material layer 13 is relatively hard, it is easy to handle the security 1, that is, the identification sticker 2 before it is attached to an object.

In order to actually identify the security 1, the reading surface 4 of the hand scanner 4 is placed on the identification seal 2 of the security 1 placed thereon.
Guess a. Then, illumination light is irradiated from the light emitting element 6 toward the hologram 2a. Then, the light diffracted by the hologram 2a is reflected toward the light receiving element 8, and when the intensity of the received light exceeds a predetermined intensity, the security 1 is identified as a regular security. Therefore, for example, even if you obtain Securities 1 for the purpose of forging, it is not only technically extremely difficult to analyze the diffraction characteristics of the hologram and forge it, but it also costs a lot of money to create a similar hologram. This makes counterfeiting virtually impossible.

Further, as shown in FIG. 5, when the identification sticker 2 is pulled off by pinching the edge of the identification sticker 2, the cushion layer 11 is elastically deformed, but the hologram reflective layer 10 is plastically deformed, and its diffraction Because the characteristics change, it is also possible to instantly identify fraud in which a genuine identification sticker is removed from a genuine object and replaced with a counterfeit one. At this time, when the identification sticker is removed and replaced with a counterfeit item, it is not possible to confirm that the diffraction characteristics have changed, and the fraudulent act is discovered only after identification using optical identification means. Violators can be exposed.

[0020] For example, if reinforcing fibers or the like are buried in the cushion layer 11 in a slightly contracted state to limit the amount of elastic deformation in a certain direction when the identification sticker is peeled off, the hologram reflective layer 10 at that time can be Since the amount of plastic deformation is determined, by investigating the diffraction characteristics after this plastic deformation in advance, fraud was carried out in which the above-mentioned genuine identification sticker 2 was removed from the genuine object and replaced with a counterfeit one. can be detected more accurately and prosecuted. In addition, each part 8a of the light receiving element 8
A hologram may be formed so that the illumination light is diffracted and reflected toward any four locations between 8h and 8h or more.

In reality, the above-described security 1 may be slightly deformed, but as shown in FIG. 6, a certain degree of deformation is absorbed by the cushion layer 11. In addition, since the diffraction characteristics of holograms and diffraction gratings (described later) hardly change even if they are deformed by about 5 degrees, for example, curved parts such as tennis racket handles, bottles, bags, various clothing items, and general-purpose packages can be used. It can also be easily affixed and used for identification.

FIG. 7 is a diagram similar to FIG. 5 showing a second embodiment to which the present invention is applied, and the same parts as in the first embodiment are denoted by the same reference numerals, and a detailed explanation thereof will be given. omitted.

In this embodiment, the cushion layer 11 and the securities 1
The cushion layer 11 is directly bonded to the securities 1 by an adhesive layer 22 without interposing a base material layer between them. This adhesive layer 22 adheres to the security 1 with an adhesive force that causes the cushion layer 11 to elastically deform and the hologram reflective layer 10 to plastically deform when the identification sticker 2 is peeled off.

Therefore, in this embodiment, compared to the first embodiment, since there is no base material layer, the manufacturing process can be simplified, although the ease of handling when pasting the identification sticker 2 is slightly lowered. In addition, if the adhesive used in the adhesive layer is, for example, a solid adhesive that can maintain its shape when not softened, the handleability will not deteriorate even if a base layer is not used.

In each of the above embodiments, a hologram having a unique diffraction characteristic was used as the light reflecting surface of the identification sticker 2 attached to the security 1, but it is possible to obtain the same effect by using a diffraction grating. Needless to say.

In addition, in each of the above embodiments, a hand scanner is used for the identification structure, but the scanner side may be fixed and the object side may be transported to a position corresponding to the scanner.

As described above, according to the present invention, an identification sticker has a light reflecting layer provided with a light reflecting surface having a unique diffraction characteristic that can be identified by an optical identification means, and By attaching this identification sticker to an object and peeling it off, the light-reflecting layer plastically deforms and changes its diffraction characteristics.If this identification sticker is affixed to the object, it is possible to make counterfeit identification stickers cost-effective using printing technology. Not only is it difficult to counterfeit objects to which this identification sticker is affixed, but also it is difficult to forge an object to which the identification sticker is affixed. Since there is no major change in the number and the diffraction characteristics change, it is possible to accuse fraudsters of re-sticking without being noticed by those who intend to commit fraud, improving the anti-counterfeiting effect and It becomes possible to improve the identifiability of objects, and to fundamentally reduce fraudulent acts caused by replacing official identification stickers. Further, if a base material layer with high strength is provided, the ease of handling when attaching an identification sticker to an object is improved. From the above, the effects of the present invention are significant.
