2. Description of the Related Art Conventionally, checks, bills, certificates of deposit, passbooks, deposit balance certificates, pledges, identification cards, driver's licenses, passports, resident's cards, certified copies of family registers, seal certificates,
Stock documents, tax payment certificates, and other written documents that describe certain items are used in large quantities and play an extremely important role in maintaining the social economic distribution order and legal order.

On the other hand, recently, color copiers, monochrome copiers, simple printers, computer graphic software, etc. have been sold as extremely sophisticated, high-quality and inexpensive products due to technological advances. . As a result, the imprint, the signature, the name display of the issuer, etc. were illegally copied from the written document describing certain items as described above, and this was copied or pasted on another written document of the same form. Forgery has come to be made by further color copying things.

Those who do not have any special technique can perform these actions without using any special technique due to the spread of color copying machines, monochrome copying machines, simple printing machines, etc. as described above.
It can be done easily.

The invention of Japanese Patent Laid-Open No. 6-259013 has been proposed as a means for preventing such counterfeit crime. In this method, a transparent or translucent film formed with a hologram or diffraction grating over the entire surface, the coating film similarly provided with a transparent or semi-transparent metal thin film layer, indicia
Kagematawa imprint and fixed to the sign or the issuer of the mark of the surface
Or , it covers the signature or the stamp of the issuer .
When the imprint or the signature or the issuer's seal using this method is copied, as shown in FIG. 8, the imprint or the signature or the issuer 's seal of the portion corresponding to the image of the hologram (20).
A hollow spot (21) occurs at the bottom. Therefore, it was found that it was a copy, and the imprint or signature
Or , in order to reproduce the issuer's mark (20) without any voids, a high degree of special technology is required, which has the advantage of being extremely difficult to reproduce.

[0006]

However, when a hologram or a diffraction grating is covered with a semitransparent paper or film having a surface with minute irregularities such as tressing paper, the reflection of the hologram or the diffraction grating is reduced. It will disappear. Therefore, if the surface of the coated film having a hologram or a diffraction grating is covered with semi-transparent paper or film having minute irregularities on the surface and copied, as shown in FIG.
It has a defect that a clear copy without (21) can be obtained.

[0022]

Since the present invention is constructed as described above,
When this is used to prevent the forgery of a seal imprint or signature or the stamp of the issuer , the cover film shall be used for the purpose of preventing forgery such as signature, amount display, seal imprint, rubber stamp of the issuer, print indication, or signature or issue. On the surface of the person's mark , at least one of the hologram and the hollowed-out portion formed in white
It is placed so that it overlaps with the imprint or signature or the stamp of the issuer, and is attached to the document by the adhesive force of the adhesive layer.

When this fastening is performed, the hollow forming portion formed of semitransparent or opaque white that reflects the light of the copying machine,
Some of the imprint or sign or the issuer of the mark although difficult to see, so that it is possible to confirm who is easily determined an overall picture of the imprint or sign or issuer indicia, not the entire medium disconnect forming portion Therefore, by forming a narrow line, such as a thin line or a dot , at one place or a plurality of places, there is no obstacle to confirmation. In addition, imprint or signature
Or, the issuer's mark can be easily visually confirmed through the transparent or translucent coating film and does not hinder the confirmation.

Since the hologram or diffraction grating provided on the coated film is also transparent or translucent, it does not hinder the visual confirmation of the imprint or the signature or the issuer's signature . Further, these treatments are not applied to the entire surface of the coated film as in the conventional case, but one place or
Since it is provided partially at multiple locations, there is little irritation due to diffuse reflection of light, and the imprint or signature or issuer's
This effectively suppresses eye fatigue of the person who confirms the mark . Therefore, it is possible to improve the work efficiency of collation and confirmation of the seal imprint or the signature or the stamp of the issuer, and other office work. In addition, the seal imprint of the coating film or the signature or
At the time of covering the mark of the pedestrian , the hologram or the diffraction grating and the hollow forming part formed in white are imprinted or signed or
Fasten it over the issuer's seal .

[0025] Then, the person who is going to commit fraud is
An imprint or sign with a hollow film formed in white and a hologram or a coating film provided with a diffraction grating.
Or , if the stamp of the issuer is copied as it is, all the corresponding portions of the semi-transparent or opaque white hollow forming portion that reflects light during copying are copied in a white hollow state.

In the portion corresponding to the hologram or the diffraction grating, the imprint, the signature, or the issuer's mark has a spot-like void. Then, this hologram or diffraction grating is clearly displayed by the presence of a colored coating film or a colored layer provided on the back surface of the uncolored coating film,
This makes it possible to strongly express the state of the void. These, by in loss effect white by disconnect forming unit and the hologram or diffraction grating in which is formed a white, copy thereof is made possible to clearly determine that is a copy.

When the surface of the coating film is covered with a cover film such as semitransparent paper or film having fine irregularities on the surface, spot-like hollow portions corresponding to holograms or diffraction grating portions disappear. However, since the white hollow forming portion is formed to be semi-transparent or opaque to reflect the light of the copying machine, the corresponding portion of the copy is surely copied in the white hollow state. The imprint or sachet that produced this white hollow
Restoration of the sign of the in or issuer using computer graphics etc. requires advanced special technology and it is extremely difficult to forge, and this forgery does not require complicated machines, etc. It can be easily discriminated by human eyes.

Further, the hollowed-out forming portion formed in white may be formed on the back surface of the coating film by printing, or may be formed by fixing the colored film on the back surface of the coating film at appropriate intervals. It may be. Also, this white
The hollowed-out portion should be made semi-transparent or opaque so that it overlaps with the imprint or part of the signature or the stamp of the issuer, and even if the copy density is increased, white voids are surely formed. It is formed with a shade that reflects the light of the copying machine. This is because, when processing with computer graphics, partial deletion can be performed relatively easily, but it is extremely advanced technology to replenish and add white hollow areas to the extent that visual discrimination is difficult. It costs.

That is, if the shade of the hollow portion is a dark shade that absorbs the light of the copying machine, increasing the copy density causes a white imprint in the imprint or the signature or the stamp of the publisher. Instead, it is possible to copy the corresponding part in black. That is, the seal imprint, the signature, or the stamp of the issuer is not a white void, but is partially painted. Such painting can be easily forged because it is possible to delete unnecessary portions by computer graphic technology.

However, since the light- reflecting white color is used for the hollow portion forming portion, the hollow portion forming portion is surely copied white even if the copy density is increased. By a computer graphic or handwritten, seal image or signature Moshiku
Since it is extremely difficult to add a white void portion that occurs in the stamp of the issuer, it is possible to effectively prevent counterfeiting. Further, since the middle disconnect forming unit using a white to reflect light, also be translucent cause voids of white on the copy was possible, in imprint or sign during normal
Alternatively, it becomes easy to confirm the issuer's seal . Further, if the hollow portion formed in white is made opaque, a more reliable white hollow can be formed.

The colored layer is a visual impression or a seal.
If it is easy to confirm the mark of the printer or the issuer, it may be formed by printing, or may be formed by fixing an appropriate colored film. Further, since the purpose of the colored layer is to color the coated film, if the purpose can be achieved, the colored layer is not formed, and the coated film is colored by mixing the colorant and the resin raw material. It may be done by doing.

Further, a seal impression of the document or a signature or issuance
Depending on the size and density of the person's mark, the hollow forming part formed in white has a width of 0.1 mm to 2.0 mm .
When the seal is copied, a white void is clearly generated, which makes it possible to prevent counterfeiting well, and also becomes a hindrance when the confirmer visually confirms the imprint or the signature or the issuer's seal. There will be nothing.

Then, the hollow portion formed in white is 0.1 m
If the width is narrower than m, the imprint or sign or
Almost no white voids are formed when copying the stamp of the issuer, or the shape of the signature etc. is simple and large imprint or
In the case of an in or stamp issued by the issuer, there is a risk that the white void will be easily repaired and forgery will be easily performed. On the other hand, if the hollowed-out forming part formed in white is formed with a width wider than 2.0 mm, a small and precise imprint such as imprint or
In the case of a signature or the stamp of the issuer, a seal imprint at the hollow forming unit
Or, the signature or the stamp of the issuer is almost hidden, making it difficult to visually confirm. Therefore, imprint or signature
Alternatively, when the stamp of the issuer is a seal imprint, it is preferable that the hollowed-out forming portion formed in white has a thickness of 0.4 mm to 0.8 mm.

[0034]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the present invention will be described below with reference to the drawings. (1) is a seal imprint or a signature or a seal of an issuer . It is displayed on a written document having a certain economic value, a written document proving a certain fact, and the like.

An imprint or a service having this certain economic value
The written documents showing the stamp of the inn or the issuer (1) include bills, checks and the like. In addition, as a document showing the imprint or signature or the issuer's seal (1) that proves certain facts, deposit certificates, deposit passbooks, deposit balance certificates,
Pledge setting documents, identification documents, driver's licenses, passports, resident cards, certified copies of family registers, seal certificates, stock certificates, tax certificates, etc.

When it is desired to forge a seal impression such as a seal impression or a signature or the issuer's seal (1) from these description documents, the officially issued description document is copied by color copying. Then, the imprint such as the copied imprint or the signature or the stamp (1) portion of the issuer is cut off and removed, and this is a legitimate written document on which the seal or the like is not written, or the imprint or signature or
Stick it on the counterfeit written document on which the issuer's seal (1) is not written. By making a color copy again, it is possible to forge the written document. In another method, the image of the imprint or the signature or the stamp of the issuer is forged using computer graphics.

In the embodiment of the present invention, a seal imprint or signature for the purpose of preventing forgery or a signature of the issuer is fixed on the written document .
As the coating film (2) for coating the mark (1), a suitable transparent or translucent film such as polyethylene terephthalate is used with or without coloring. Then, on this coating film (2), a seal image or a signature or a seal of the issuer (1)
Holograms (3) or diffraction gratings formed at narrower intervals are formed.

As shown in FIG. 1, the hologram (3) or the diffraction grating forms unevenness (4) by embossing on the entire surface of the coating film (2) and, as shown in FIG. (3) is formed on the back surface of (1) to form a vacuum vapor deposition section (5) by providing small circles at fine intervals. This vacuum deposition unit
(5) is not formed on the entire surface of the coating film (2) that covers the seal imprint or the signature or the stamp (1) of the issuer, but a part.
Separately, it is formed at one or more places. Only the portion where the vacuum vapor deposition portion (5) is formed acts as a hologram (3) or a diffraction grating and diffusely reflects light.

[0039] The hologram (3) or grating is formed partially single location or multiple locations rather than formed as described above over the entire surface, the case of providing a plurality of locations, marked
It is provided at a narrower interval than the shadow or signature or the stamp (1) of the issuer . Therefore, when the covering film (2) is fixed, at least a part of the imprint or signature or the stamp (1) of the issuer is covered with the hologram (3), but the hologram (3) is formed on the entire surface of the covering film (2). Is not meant to be displayed.

Further, the hologram (3) or the diffraction grating is used as a whole.
If the film is not formed on the surface but only partially provided, the covering film (2) should be imprinted, signed or printed.
When covering the person 's seal (1), the seal imprint or signature or
The hologram (3) or the diffraction grating is attached so as to overlap the issuer's mark (1).

In this embodiment, the rectangular hologram (3) is arranged in parallel with both side edges of the covering film (1) under the above conditions as shown in FIG. However, as another different embodiment, the hologram (3) or the diffraction grating may be formed by arranging the hologram (3) perpendicularly or obliquely to both side edges of the coating film (1). Both side edges of the diffraction grating may be formed in a curved shape such as a waveform.

Further, the back surface of the coating film (2), the translucent or opaque white, 4, as shown in FIG. 5,
White hollow forming part formed by printing linearly
(6) is formed. Hollow-out formation part formed with this white color
(6) is not formed on the entire surface of the coating film (2)
One or more lines are partially formed. When forming multiple lines, as shown in Figure 5, imprint or signature or issuer
By arranging through a narrower space than the mark (1),
White or hollowed-out part (6) and imprint or sign
Are formed so that the issuer's mark (1) always overlaps.
Further, in the case of a disconnect forming portion in which is formed a white (6) partially one only, disconnect forming portion in this one (6) a stamp imprint also
Is the imprint of the covering film (2) or the signature or issuer's seal (1) so that it overlaps the signature or the issuer's seal (1).
To be coated on.

And, the hollow forming portion (6) formed in white
Considering the size and minuteness of the imprint or signature or the stamp (1) of the issuer , the forming width is preferably set to 0.1 mm to 2.0 mm. When the stamp is used as in this embodiment, the width of the white hollow forming portion (6) is 0.4 mm.
Imprint or signature or issuer if formed with ~ 0.8mm
The mark (1) clearly shows white hollow and prevents forgery, and is easy to visually confirm.

Further, the hollowed-out forming portion (6) formed in white
If it can be overlaid with the imprint or signature or the stamp (1) of the issuer, it is formed by arranging a plurality of hollow forming parts (6) on the covering film (2) in a grid pattern or at random. Alternatively, only one may be partially formed.

Further, the white hollow forming portion (6) is
It may be formed by fixing a colored film instead of printing. In addition, the hollow forming part formed with this white color
(6) may be formed not on the back surface of the coating film (2) but on the front surface, but by stamping out the hollow forming portion (6) with a cutter knife or the like, the imprint or signature or the issuer's seal (1)
Is clearly displayed and there is a risk of counterfeiting, so it is preferable to form it on the back surface of the coating film (2) as in this embodiment.

Further, the hollowed-out forming portion (6) formed in this white color
The colored layer (7) is formed on the back surface of the coating film (2) with the coating film (2) interposed therebetween. This colored layer
(7) makes it possible to clearly display the hologram (3) and the diffraction grating. Further, the coloring layer (7) may be formed by printing as shown in FIG. 1, or as shown in FIG. 2, the coloring film may be attached to the back surface of the covering film (2) via an adhesive (8). You may wear it.

The purpose of the colored layer (7) is to color the coating film (2). Therefore, if the purpose can be achieved, the colored layer (7) is not formed, The coating film (2) may be colored by mixing a colorant and a resin raw material when the coating film (2) is formed. In this case, the coated film
Without the manufacturing means of (2), the coating film of the same color
Since it becomes difficult to produce (2), the coated film
(2) It will be effective in preventing duplication of itself.

Further, the imprint or the support is formed on the back surface of the colored layer (7).
An adhesive layer (9) is formed to cover the inside or the stamp (1) of the issuer and fix it to the document. Then, colored layers of the embodiment shown in FIG. 2 the colored film to form a (7), be formed by breakage easy film, imprint or sign Wakashi
In other words, it is possible to prevent forgery, alteration, and the like, in which the cover film (2) covering the issuer's mark (1) is peeled off and then removed.

That is, if the coated film (2) is peeled off illegally, the colored layer (7) formed of the colored film is damaged, leaving a trace of the peeling action. Even if the damaged colored layer (7) is to be restored once, if the damaged part has a little overlap, the color of the part becomes darker, and if a gap is created, the color becomes lighter and peeled off. The facts become clear.

When the coating film (2) is formed without forming the above-mentioned colored layer (7) and coloring is carried out by mixing the colorant and the resin raw material, as shown in FIG. 2)
The adhesive layer (9) is directly formed on the back surface of the. In the embodiment shown in FIG. 2, a colored layer (7) formed of a colored film was adhered to the back surface of the coated film (2) with an adhesive (8), but it was fixed with an adhesive. Is also good.

In the structure constructed as described above, this is printed.
When used to prevent the forgery of shadows or signatures or the stamp (1) of the issuer , the coated film (2), as shown in FIG. 5, is a signature, an amount display, a seal imprint, a rubber stamp of the issuer, a printed display, etc. It is attached to the surface of the seal imprint or signature or the stamp (1) of the issuer . Even with this fastening, the seal imprint or seal
The mark (1) of the printer or issuer can be easily visually confirmed through the transparent or translucent coating film (2), hologram (3) and colored layer (7) as shown in FIG. it can.

When the white hollow forming portion (6) is made opaque, the imprint of the portion overlapping the opaque hollow forming portion (6) or the signature or the stamp (1) of the issuer.
Becomes a white hollowed out state and cannot be visually confirmed,
The imprint or signature or the issuer's seal (1) is formed as thin as possible so that it does not interfere with the confirmation of the imprint or signature or the issuer's seal (1) as a whole. Is not an obstacle to grasp. Therefore, for example, the imprint or signature of the withdrawal slip or the stamp of the issuer ,
It is possible to reliably perform the collation with the imprint or the signature or the stamp (1) of the issuer .

Then, in this visual confirmation,
Since the coating film (2) and the colored layer (7) are formed transparent or translucent, there is no obstacle. Also, the hologram (3) and the diffraction grating can be visually confirmed, but they do not hinder the confirmation of the imprint or signature or the issuer's seal (1). Further, by providing the coloring layer (7) or coloring the coating film (2), the hologram (3) and the diffraction grating can be clearly displayed as compared with the case where the coloring layer (7) is not provided. As a result, the diffuse reflection effect of light is enhanced.

Further, the hologram (3) or the diffraction grating is
The hologram is not provided on the entire surface of the coating film (2) but is partially provided at one or a plurality of locations.
(3) and the diffuse reflection of light by the diffraction grating is reduced,
Imprint or imprint of the part without hologram (3) or diffraction grating
Makes it easy to confirm the signature or the stamp (1) of the issuer . Therefore, it is possible to alleviate the irritation given to the confirmer's eyes, effectively suppress eye fatigue, and improve the work efficiency of visual confirmation and collation.

Then, the person who tries to forge is the seal imprint or signature or the issuer who has been coated with the coating film (2) .
If you copy the mark (1) as it is, it will be white as shown in Fig. 6.
In the corresponding portion of the disconnect forming portion in which is formed (6) (10), a total
It is copied with a white void. Also, hologram (3)
Alternatively, in the diffraction grating portion, due to the diffused reflection effect of light, the corresponding portion becomes a spot-like spot (11), which results in a void. The hollowing out due to the hologram (3) or the diffraction grating is effectively performed by the coloring of the coating film (2) itself or the coloring layer (7) on the back surface. Due to such a hollow effect, it is possible to clearly discriminate that the copied image is a copied image, and it is extremely difficult to restore it by handwriting, computer graphics, or the like.

When the surface of the coating film (2) is covered with a cover film such as semitransparent paper or film having fine irregularities on the surface, irregular reflection of light is prevented, and the hologram (3) or the film is rotated. The hollow portion (11) corresponding to the diffraction grating portion disappears and is copied as shown in FIG. However, since the white hollow forming portion (6) originally reflects the light of the copying machine, its corresponding portion (10)
Is definitely copied with a white void. And, of imprint or sign or the issuer resulted in the omission in this white
Restoration of the mark (1) using handwriting or computer graphics is extremely difficult and cannot be counterfeited.

The hollow forming portion (6) is made of a color other than white.
FormedHas no effectFor dark colors such as black, black, etc.
Since it absorbs the light of,
Copied black,Imprint or signature or stamp of issuer

Technology such as computer graphics, IEliminate minute black lines
Is easy to remove,Imprint or signature or departure
Mark of personIt is possible to forge (1). for that reason,
The hollow forming part (6)Copy black even if the copy density is increased
Light-reflecting whiteBy colorIf not
Yes.

In the above embodiment, the imprint or signature
Ideally, the hologram (3) or diffraction grating formed with a width narrower than the publisher's mark (1) should be used on the entire surface of the coating film (2).
Without a partial imprint or signature or the stamp (1) of the issuer, by providing it at one or more locations on the coating film (2), a hologram (3) or a diffraction grating is used to imprint or sign or issue. Part of the person's mark (1) can be surely covered.

However, the imprint or signature or issuer's
If the mark (1) can be covered, the hologram (3) or the diffraction grating may be provided not at the entire surface of the covering film (2) but at only one place. In this case, imprint or signature
Is the office worker who attaches the anti-counterfeiting seal to the issuer's seal (1), the hologram (3) or the diffraction grating, and the seal or seal.
If the hologram (3) or diffractive grating is used, the imprint or signature of the hologram or the issuer's seal (1) will be ensured by making sure that it overlaps with the issuer's or issuer's seal (1). Can be generated, and the labor and cost of manufacturing can be reduced as compared with the case where a plurality of them are provided.

Further, in the above embodiment,Formed in whiteDuring ~
The punch forming part (6) alsoImprint or signature or stamp of issuer

Be careful not to attach it to the hollow-out forming part (6).
According toImprint or signature or stamp of issuer(1)whiteHollow
It is possible to reliably generate an injury.

[0061]

Since the present invention is configured as described above, the coated film is imprinted with a seal or a signature or an issuer.
It is fixed to the surface of the mark of, Wakashi imprint or sign such as seal impression
In addition, the issuer's mark can be easily confirmed visually and does not hinder verification. And the imprint or signature or issuer covered with this coating film
If you copy the mark as it is , the corresponding part of the hollow forming part that is partially translucent or opaque white instead of the entire surface becomes a white hollow state, and the hologram or diffraction grating part corresponds. It is clear that the part to be copied is a copy, and it is clear that it is a copy.

Further, a seal imprint or a safing with a covering film attached
The sign of the in or the issuer is difficult to see the portion overlapping the hollow formation portion when the hollow formation portion formed in white is opaque, but the imprint or the signature or the stamp of the issuer. not become an obstacle to grasp the whole picture of, imprint or sign young
Or, it is possible to surely perform the collation and confirmation work of the stamp of the issuer .

When the surface of the coated film is covered with a cover film such as semitransparent paper or film having fine irregularities on the surface, spot-like hollows due to holograms or diffraction gratings disappear, but hollowing out occurs. Make sure the corresponding part of the forming part
It is copied with a white void. Then, it is extremely difficult to restore the imprint having the white void or the signature or the stamp of the issuer using computer graphics, handwriting, etc., and it is impossible to forge.

Further, the hologram or diffraction grating is not formed on the entire surface of the covering film, but is partially formed at one or a plurality of places. Therefore, compared with the case where the hologram or diffraction grating is formed on the entire surface of the coating film, the diffuse reflection of light is reduced and the stimulus given to the observer's eyes is suppressed, so that eye fatigue can be effectively prevented. Becomes As a result, the imprint or signature or issuer's
It is possible to improve the work efficiency of collation and confirmation of marks and other office work.

Further, since the coated film can be used by being fixedly attached to the conventionally existing written document, the existing written document can be used as it is, and the document having a high anti-counterfeit effect can be obtained. Therefore, it is possible to prevent counterfeiting at a low price without wasting the existing written document itself.
