Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a method of transferring a code portion such as a hologram code sheet to a card or the like and a method of using the code portion to judge the authenticity of a card by using such a coat portion. It is about.

[0002]

2. Description of the Related Art FIG. 5 is a diagram showing an example of a forgery method of a card having a magnetic recording portion. The card 31 is shown in FIG.
As shown in (A), a stripe-shaped magnetic recording portion 32 is formed. The magnetic recording section 32 is cut into two in the longitudinal direction, and as shown in FIG.
Make 32B. These magnetic recording units 32A and 32B are
As shown in FIG. 4C, the used cards 31 ′, 3
Two similar cards can be made by sticking together the 1 "magnetic recording parts 32 ', 32" without the magnetic recording parts.

In order to prevent such forgery, it has been proposed to form a hologram portion on the card in addition to the magnetic recording portion. For example, in Japanese Patent Laid-Open No. 3-71383, as shown in FIG. 6, on the main surface 31a of the card 31,
It is proposed that four hologram sections 34 to 37 are provided. The hologram parts 34 to 37 are manufactured so that the illumination light from the light emitting element 41 is reflected and condensed at two different positions, and the hologram parts 34 to 37 are also different in condensing position. There is. Further, four light receiving elements 42 to 45 are provided at each condensing position.

The hologram section 34 reflects the illumination light from the light emitting element 41 toward the light receiving elements 42 and 43 and collects it (FIG. 6), while the hologram section 35 receives the illumination light from the light emitting element 41. The light is reflected and condensed toward 43 and 45. Further, the hologram portions 36 and 37 are similarly reflected toward two of the light receiving elements 42 to 45 and focused. In this way, the reflected light from the hologram parts 34 to 37 can be used as a code signal.

[0005] Holograms can themselves be manufactured by only a few manufacturers, and the number of manufacturers that have the technology to put information in holograms is further limited. Therefore, providing such a hologram portion on the card and reading the information in the hologram portion for checking at the time of encoding or using the card can be expected to dramatically improve the security of the card.

[0006]

However, when a code is created by the hologram section described above, if the code has few variations or can be easily analyzed, it is forged by cutting and pasting. If many codes are to be created by the hologram section, many molds must be provided, which leads to an increase in cost. Further, it is conceivable to attach the hologram code portion to one die in multiple ways, but there is a limit to the variation.

The object of the present invention is to solve the above-mentioned problems and
It is to provide a transfer method of a code part capable of transferring various kinds of code parts even though it is a code sheet created by one mold, and a method of using the code part by which the authenticity of a card can be easily judged by the code part. ..

[0008]

In order to solve the above-mentioned problems, the transfer method of the code portion according to the present invention is such that a pattern selected from a group of P kinds of patterns is selected from an area in which Q pieces are arranged in one direction. Formed in the formed region, and the Q
It is characterized in that a transfer sheet in which individually arranged regions are repeatedly formed in the one direction is used to transfer R regions each selected as a code portion from the Q arranged regions. In this case, the greatest common divisor of the R and the Q is 1, and the R or the Q is not 1. Further, the arrangement of R pieces can be characterized by shifting one pattern when the same pattern is repeated.

On the other hand, in the method of using the code part according to the present invention, the hologram code part in which different machine-readable information is coded is transferred onto a card having a magnetic recording part by using the transfer method of the code part. Then, the code in the hologram code section is read at the time of encoding, the magnetic information corresponding to the code is recorded in the magnetic recording section, and the code in the hologram code section and the magnetic information in the magnetic recording section are read when the card is used. It is characterized by matching them and judging the authenticity of the card.

[0010]

According to the present invention, Q types of localized P patterns are arranged in the circumferential direction of the mold, and a transfer sheet for a code portion by a hologram or the like is prepared. Since R lines are selected and transferred, 1
It is possible to transfer many kinds of code parts with one mold.

As described above, since a large number of different code portions of information can be transferred, if the information of the code portion is recorded in the magnetic recording portion, both the information of the code portion and the information of the magnetic recording portion are collated at the time of use. This makes it possible to easily determine the authenticity of the card.

[0012]

The present invention will be described in detail below with reference to the drawings and the like. 1 to 4 are views for explaining an embodiment of a method of transferring and using a code portion according to the present invention, FIG. 1 is a view showing a raw material of a transfer sheet, and FIG. 2 is a view showing a transfer method. Figure, Figure 3 shows the created card,
FIG. 4 is a sectional view schematically showing the hologram code section.

Original hologram code 10 of this embodiment
Is a regionized P type pattern a, b, c, d,
It is a transfer sheet in which Q pieces are repeatedly arranged in the circumferential direction of the mold (sheet flow direction). If the length of the circumference of the mold is L and the unit length of the patterns a to d is M, the number of repetitions Q can be provided by Q = L / M. The patterns a to d may be arranged regularly or randomly. It is preferable that the number P of the patterns a to d is not a divisor or a multiple of Q in order to increase the types of code portions.

As shown in FIG. 4, the hologram code portion 1 is of a type that is transferred by pressing or heating, and this transfer type is suitable for mass production. The hologram code portion 1 is formed by laminating a surface protection layer 5, a hologram forming layer 2 including a hologram resin layer 3 and a reflection layer 4, and an adhesive layer 6 on a base film 7 in this order, and the surface protection layer 5 is formed. The layer 5 functions as a release layer for the base film 7.

The hologram forming layer 2 is recorded as a hologram image which can be reproduced with white light of a recorded image, for example, by a relief hologram method.
For example, image hologram, rainbow hologram,
Examples include partially formed holographic gratings.

Further, the hologram image does not necessarily have to be recorded by a holographic method, and a relief diffraction grating obtained mechanically or by recording on a photosensitive material of a kind by photolithography or the like can be partially used. Those formed in can also be used. Further, as a normal product, an embossed copy of the relief shape of these records can be used. The hologram image in this embodiment also includes a diffraction pattern formed by the above diffraction grating.

The hologram forming layer 2 includes a hologram resin layer 3 having a relief surface of a hologram image formed on the lower surface,
It is composed of a reflection layer 4 formed on the relief surface of the hologram resin layer 3 for increasing the hologram effect. As a material for the hologram resin layer 3, a thermoplastic resin, a thermosetting resin, or a mixture thereof can be used. In addition, a moldable substance which has a radically polymerizable unsaturated group and is cured by heat and light or other radiation can be used. The hologram resin layer 3 is a surface protection layer 5
Although it is formed by a coating method or the like on the top, a hologram image by a relief hologram or the like may be formed on itself as long as the surface protection layer 5 can be embossed. In this case, the hologram resin layer 3 is It is unnecessary.

When used as a transparent hologram, the reflective layer 4 needs to have reflective transparency.
Examples of the material include a transparent material having a refractive index different from that of the hologram resin layer 3 and a metal thin film layer having a thickness of less than 200Å. In the former case, the refractive index of the reflective layer 4 may be larger or smaller than that of the hologram resin layer 3, but the difference in refractive index is preferably 0.1 or more, and the difference is 0. It is 0.5 or more, and more preferably 1.0 or more. In the latter case, although it is a metal thin film, its thickness is less than 200Å, and therefore the transmittance of light waves is large. Therefore, in addition to the hologram effect manifesting effect, the non-concealing effect of the lower display part, for example, is exhibited To do.

The material of the reflection layer 4 is, for example, the resin layer 3
Sb ₂ S ₃ as a transparent continuous thin film with a larger refractive index than
(3.0), ZnS (2.1) and the like. To form the reflective layer 13 on the hologram resin layer 3, a thin film forming method such as a vacuum vapor deposition method or a sputtering method may be used. For details of the material of the hologram forming layer and the manufacturing method,
It is disclosed in the applicant's US Pat. No. 4,856,857. Further, the reflective layer 4 may be a metal thin film having a thickness of 200 Å or more, and in that case, the hologram code portion 1 exhibits a silver color.

As the material of the base film 7, use is made of polymer films such as polyethylene terephthalate, polyimide, polymethylmethacrylate, polystyrene, polyvinyl butyral and polycarbonate, synthetic paper, metal films such as iron, and laminates thereof. You can

As a material for the adhesive layer 3, an adhesive such as an acrylic resin, a vinyl resin, a polyester resin, a urethane resin, an amide resin, an epoxy resin, a rubber resin, or an ionomer resin may be used. it can. The thickness of the adhesive layer 3 may be about 0.1 to 50 μm, but is preferably about 1 to 10 μm.

The hologram code original sheet 10 thus produced is cut into a predetermined length in the width direction as shown by the broken line, and the web-shaped hologram code transfer sheet 1 is cut.
1-1n are created. As shown in FIG. 2, this hologram code transfer sheet 11 is supplied from a supply roll 21 and transferred onto a card 31 by a transfer head 23 between guide rolls 22 and 24, and only a base material sheet is taken up by a take-up roll 25. Wound up by.

In this transfer type hologram code section 1, the adhesive layer 6 is superposed on the card 31, and the transfer head 23 is formed.
Allows for quick and easy application and then
The base film 7 is peeled off from the surface protective layer 5.

At this time, as shown in FIG. 1, from the P patterns of the hologram code transfer sheet 11,
A sequence of R pieces is sequentially selected and transferred. The same pattern is repeated in the transfer of the order of, and when the repetition occurs, the patterns are shifted by one and transferred as shown in. Similarly, ...
-By shifting the pattern by one each, the number of codes can be increased significantly. Further, by selecting P or Q so that the greatest common divisor of R and Q becomes 1, it is only necessary to sequentially select and transfer an array of R units,
Maximum number of codes can be transferred.

Cards 31-1, 31-2, 31-3, ...
.., as shown in FIG.
In addition to -2, 32-3, ..., the hologram code section 33 having different code information by the method described above-
1, 33-2, 33-3, ... Are formed. Each card 31 reads the code of the hologram code section 33 at the time of encoding and writes information corresponding to the information in the magnetic recording section 32. When used, the magnetic recording unit 32
The information of the hologram code section 33 is read, and if the consistency cannot be obtained, the card is rejected as a forged card.

The information in the hologram is invisible to the naked eye, and in the case of this embodiment, it is possible to have more than 100 variations. Therefore, the possibility of forgery due to simple cutting and pasting, magnetic tape pasting, etc. is greatly reduced. Further, even if the reader / writer is stolen and the inside is analyzed, the possibility of alteration and forgery is reduced because the hologram is rich in variations and it is difficult to forge the hologram.

Although a card has been described in this embodiment, it may be transferred to a document or an article other than the card. Moreover, the original fabric shown in FIG. 1 may have different patterns in the width direction.

[0028]

As described above in detail, according to the present invention, it is possible to inexpensively transfer various kinds of code parts when transferring code parts such as holograms to a card or the like. In addition, various types of code parts such as holograms,
Since it is formed on a card with a magnetic recording part and the contents of the code part and the magnetic recording part are linked together, it is possible to cut and paste by giving the card itself a uniqueness together with the forgery prevention function of the hologram itself. Counterfeiting can be reduced.
