Description

  The present invention relates to a seal for preventing forgery of stamps that prevents a stamp imprinted on a savings passbook or various certificates from being forged.

  Conventionally, when carrying out procedures and contracts in financial relations and administrative relations of banks and the like, it has been performed to collate a stamp imprinted in advance with a seal stamp brought. In addition, such collation of seals plays an important procedural role in order to maintain social and legal order.

  By the way, recently, since technologies such as a copying machine, a scanner, or a simple printing machine have been greatly developed, by using these devices, it is possible to easily copy a seal stamp from the above document. There are many criminal acts to counterfeit, and this is a big social problem.

  Therefore, as a conventional technique developed to prevent such an action, the one disclosed in Patent Document 1 is called a “copy prevention seal”, and specific information is displayed as shown in FIG. A copy prevention sticker 31 that is affixed to the display unit 30 and makes it impossible to copy the display unit 30 is provided with a hologram having a predetermined image 33 or a translucent diffraction grating on the back surface of a transparent or translucent film 32. In addition, a transparent or translucent metal thin film layer and an adhesive layer are sequentially provided on the hologram or diffraction grating forming side of the film 32.

  If such a copy protection sticker is attached on a predetermined document and copied, a hollow spot will appear in the description of the portion corresponding to the hologram image, which will hinder counterfeiting and prevent forgery. It will be beneficial to you.

  However, those using holograms and diffraction gratings such as the above-mentioned anti-copying seals are expensive to manufacture, and when they are coated with translucent paper or film having minute irregularities on the surface, holograms and diffraction gratings are used. Therefore, when this is copied, a clear copy without a spot can be obtained, and it is impossible to determine whether or not the copy has been made. In addition, because holograms and diffraction gratings applied on the coating film diffusely reflect light, there are inconveniences such as giving a strong stimulus to the eyes of the confirmer at the time of collation, causing eye fatigue and causing headaches. .

  In addition, what is listed in Patent Document 2 is referred to as a “coating film for preventing forgery”, and is attached to the surface of the description item 36 for the purpose of preventing forgery of the written document 35 as shown in FIG. A line display 38 is provided on a transparent or translucent film 37 covering the surface of the matter.

  However, if such a forgery-preventing coating film is attached to the surface of the description items, the line display of the film is superimposed on the surface of the description items such as the imprint, so that the counterfeiter describes the imprint. If copying is performed by a copying machine in order to counterfeit matters, the line display is clearly displayed on the surface of the description items such as seals and the like, which may hinder forgery and prevent the forgery.

However, such a forgery-preventing coating film is only affixed to the surface of the described items, so that the counterfeiter peels off the forgery-preventing coating film as it is or removes it with a special solution or the like. If this is done, there is a disadvantage that the original description is copied as it is by a copying machine and used for counterfeiting.
Japanese Patent Laid-Open No. 6-259013 (pages 1, 2 and 4) JP-A-7-309082 (first, second, third page, FIG. 1)

  By the way, when carrying over the bankbook, a procedure was required in which the user brought the notification seal and recreated the bankbook. Recently, however, the notification seal is stamped on a sticker that can be reprinted and pasted in the column of the notification mark on the passbook. When carrying over, the seal is replaced by the bank from the old passbook to the new passbook. Since a method that simplifies carry-over operations is widespread, it is necessary to take measures for preventing forgery of seals in the same manner as described above even in such a renewal seal of a notification stamp.

  In addition, as a recent anti-counterfeiting prevention measure, banks have refrained from registering registered seals, but some banks have adopted a method of not stamping their passbooks. The inconvenience of not knowing which seal was reported to the bankbook occurs.

  The present invention has been made in view of the above circumstances, and is accurate even if a copy machine or the like is copied from a film adhering to the surface of an imprint without using a hologram or diffraction grating that is expensive to manufacture. The purpose of the present invention is to provide a seal for preventing imitation of stamps so that the imprint cannot be copied even if the imprint is copied with a copying machine after the film is peeled off. And

  In addition, the present invention provides a seal for anti-counterfeiting that is effective in preventing forgery of imprints even when the notification seal is stamped on a seal that can be replaced to simplify the carry-over procedure of the passbook. Objective.

  In addition, the present invention is designed so that the user himself / herself can determine the notification seal of the passbook of the type that does not stamp the notification seal, and the user seals the notification seal on the slip book to be kept by the user himself / herself. It is an object of the present invention to provide a seal for preventing forgery of seals that is effective in preventing forgery of the seal.

  In order to achieve the above object, the seal for forgery prevention according to claim 1 of the present invention prevents the stamp from being counterfeited by adhering to a portion covering the seal imprinted at a predetermined portion of the document. In the anti-counterfeit seal, the seal forms a transparent display layer displaying characters and symbols on the back surface of the transparent film, and a semi-transparent coating layer is provided on the back surface of the transparent film including the display layer. An adhesive layer is provided on the back surface of the transparent coating layer, and the display layer displaying the characters and symbols is attached to the document by the adhesive layer of the portion by peeling off the seal after the seal is attached to the document. The feature is that it interferes with the copying of the original seal.

  The seal for forgery / anti-counterfeiting of claim 2 is characterized in that, in claim 1, a character or symbol is shielded from being displayed on the surface of the film with the film attached to the surface of the seal. It is characterized by that.

  In addition, the seal for forgery / counterfeiting according to claim 3 is provided with an adhesive layer on the back surface of the backing paper for printing having a column to be stamped and attached to the release paper, and for preventing the forgery / forgery. The seal for sealing is formed in a shape that covers the seal mount, and the seal mount and the seal for forgery prevention are used in combination.

  Further, the seal for forgery prevention according to claim 4 is the seal of the film according to claim 1, 2 or 3, wherein a black dot pattern is applied to the entire surface of the notification mark column in the seal mount and the seal mount is covered. The whole surface of the front surface or the back surface is provided with a shielding display such as characters or symbols with reflective ink.

  A seal for forgery prevention according to claim 5 is the seal of claim 1, 2, 3 or 4, wherein the seal mount is pasted on the surface of the base seal attached to the passbook so that the seal can be replaced. With the seal stamped in the column of the notification seal, the seal mount is peeled off from the base seal of the old passbook when the passbook is carried forward by pressing the seal forgery prevention seal on the top surface of the seal mount. Is characterized in that it is attached to the base sticker attached to the new passbook.

  Furthermore, the seal for forgery prevention of claim 6 is a slip book which the user himself / herself should keep in order to discriminate the report stamp of the passbook of the type that does not stamp the report stamp in claim 1, 2, 3 or 4. A notification stamp is stamped on the seal and the seal forgery prevention is pressure-bonded to the stamped portion of the book.

  According to the seal for counterfeit prevention of the present invention, the seal forms a transparent display layer displaying characters and symbols on the back surface of the transparent film, and a translucent coating layer on the back surface of the transparent film including the display layer. In addition, an adhesive layer is provided on the back surface of the semi-transparent coating layer. Therefore, when the seal is peeled off from a state where a seal for preventing imitation of seals is attached to a predetermined document, for example, a seal stamp is obtained. When the display layer with multiple characters is attached, and this is copied with a copy machine, etc., the multiple display layers appear on the copy so as to cover the seal, so it is possible to prevent forgery of the seal by the seal It becomes.

  Further, in the present invention, a character or symbol or the like is shielded and displayed on the surface of the transparent film constituting the seal for anti-counterfeit prevention, with the transparent film attached to the surface of the imprint in a state where the imprint is blocked. As a result, if this seal for anti-counterfeiting is attached to the backing paper for printing, a part of the surface of the imprint will be blocked by the shielding display. It is possible to prevent the stamp from being forged by the imprint.

  Further, in the present invention, an adhesive layer is provided on the back surface of the backing paper having a column to be stamped and adhered to the release paper, and a seal for preventing forgery is formed in a shape covering the backing paper, By using the backing paper and the seal for preventing stamp forgery in combination, it becomes possible to contribute to a very convenient measure for preventing stamp forgery in financial institutions such as banks.

  Also, in the present invention, by applying a black halftone dot pattern on the upper surface of the notification mark column of the seal mount, when the upper surface of this column is imprinted, a vermilion color forming an imprint is formed on the upper part of the black dot pattern. Although this is clearly expressed, when this is scanned by an optical device, the vermilion of the imprint is unclearly expressed in a white halftone dot portion other than a fine black halftone dot pattern.

  In addition, when a film with a shielding display with fine reflective characters etc. is pressed on the upper surface of the imprint of the stamping board, scanning with an optical device from the upper surface matches the above halftone dot effect. The irregular reflection of light with respect to the fine shielding display having reflectivity causes a defective portion in the imprint, making it impossible to read the correct imprint.

  In addition, it is possible to prevent the stamping counterfeiting on the top surface of the stamping board in a state where the stamping sheet is pasted on the surface of the base seal stuck on the passbook and the seal is stamped in the notification mark column of the stamping board. Work to carry over the passbook by pasting the seal mount peeled off from the base sticker attached to the old passbook on the base seal attached to the new passbook Can be greatly simplified, and even in such a re-covering type printing board, the effect of preventing forgery of the seal of the present invention can be exhibited.

  In addition, the present invention is designed to determine a notification stamp of a passbook of a type that does not stamp a notification stamp, and a notification stamp is imprinted on a note that the user himself / herself should keep, and the present invention is marked at the stamped portion of the slip. By sticking the seal for anti-counterfeiting, it becomes possible to visually discriminate the seal owned by the user and the seal imprint of the book. In addition, it is possible to prevent forgery of the seal by attaching the seal for anti-counterfeiting of the present invention to the seal of the book so that the seal is not forged by the seal imprinted on the book.

  Embodiments of the present invention will be described below with reference to the drawings.

  The specific cross-sectional structure of the seal for preventing counterfeiting of the present embodiment will be described. As shown in FIG. 2A, a transparent silicone material is used as appropriate on the back surface of the transparent film 2 made of a transparent synthetic resin (for example, polyethylene terephthalate). Are formed on the back surface of the transparent film 2 including the display layer 3 and a translucent coating layer 4 by printing or the like. Further, an adhesive layer 5 made of a transparent fluororesin or the like is provided on the back surface of the translucent coating layer 4.

  With such a configuration, as shown in FIG. 2A, when the seal forgery prevention sticker 1 is attached to the document 6, there is a display layer 3 displaying characters and symbols on the back surface of the transparent film 2. Since the display layer 3 is transparent, the characters are not displayed through the transparent film 2 and the color of the translucent coating layer 4 adhered to the entire back surface of the transparent film 2 is exhibited. Thus, by coloring the translucent coating layer 4 in a translucent color, it is possible to clearly see the description of the document 6 through the translucent coating layer 4 from above the transparent film 2.

  Next, as shown in FIG. 2B, when the above-described seal 1 is peeled off, the adhesion between the display layer 3 made of the silicon resin material and the translucent coating layer 4 is the weakest, so characters and symbols are displayed. Only the portion of the display layer 3 is kept attached to the document 6, and the remaining translucent coating layer 4 is attached to the transparent film 2 side together with the adhesive layer 6 and peels off from the document 6. As a result, only the portion of the display layer 3 on which characters and symbols are displayed adheres to the document 6, and the lower semi-transparent coating layer 4 is colored, and is displayed as characters and symbols on the document 6 in that color. Is done.

  When a plurality of such seals 1 of this embodiment are attached to the release paper 8 and arranged in a row, the sheet shape shown in FIG. In addition, what is shown in FIG. 1A is an arrangement in which an adhesive layer is provided on the back surface of the backing paper 10 and a plurality of sheets are attached to the release paper 8 and arranged.

  As shown in FIG. 4, the description items on the seal mount 10 are printed as a verification example of a registered seal (imprint) 12 attached to the savings passbook 11 as shown in FIG. 3. Further, a notification mark 12 and a mark 13 of the reception staff are stamped at predetermined positions on the surface of the paper piece, and a seal 1 for preventing forgery of seals according to this embodiment is attached to the surface.

  Therefore, by providing a combination of the sheet 14 in which the seal mount 10 is arranged on the release paper 8 and the sheet 15 in which the seal counterfeit prevention seal 1 is arranged on the release paper 8 as described above, It is possible to contribute to a very convenient anti-counterfeiting prevention measure at an institution.

  Further, in the present embodiment, as shown in FIG. 4, a portion that blocks the imprint 12 in a state where the transparent film 2 is adhered to the surface of the imprint on the front or back surface of the transparent film 2 of the seal 1 for preventing forgery of seals. A shield display 16 such as characters or symbols is provided on the screen.

  As shown in FIGS. 4 and 5, the content of the shielding display 16 is an example in which a plurality of characters “BANK” are arranged. When such a seal 1 for anti-counterfeiting is attached to the above-described seal mount 10, the shielding display 16 blocks a part of the surface of the notification mark (imprint) 12. Accordingly, when copying with a copying machine or the like with the sticker 1 attached, the shielding display 16 appears on the copy so as to cover a part of the imprint 12, and forgery of the seal by the imprint 12 can be prevented. It becomes.

  In addition, the shielding display 16 such as characters or symbols printed on the front or back surface of the transparent film 2 of the seal forgery prevention sticker 1 is light and small so as not to interfere with the verification of the seal by the relationship, and is a copy. It is preferable that a part of the image be shielded during copying by a machine or the like.

  Further, when the seal 1 is peeled from the state where the seal 1 for preventing forgery is attached to the seal mount 10 as shown in FIG. 4, a plurality of “seal stamps” are formed on the seal 12 as shown in FIG. When the display layer 3 with characters is attached and is copied by a copying machine or the like, the plurality of display layers 3 appear on the copy so as to cover the seal imprint 12, and the counterfeiting of the seal stamp by the imprint is also prevented. It becomes possible.

  The seal for forgery / anti-counterfeiting of this example has the same laminated structure as that of Example 1. That is, as shown in FIG. 2 (a), an appropriate character (for example, a character “seal stamp” shown in FIG. 10 is formed, and a translucent coating layer 4 by printing or the like is provided on the back surface of the transparent film 2 including the display layer 3, and the translucent layer is further displayed. An adhesive layer 5 made of a transparent fluorine resin or the like is provided on the back surface of the coating layer 4.

  Therefore, as shown in FIG. 2B, when the seal 1 is peeled off, only the portion of the display layer 3 displaying characters and symbols is kept attached to the document 6, and the remaining translucent coating layer 4 is bonded. Attached to the transparent film 2 side together with the layer 6 and peeled off from the document 6. As a result, only the portion of the display layer 3 on which characters and symbols are displayed adheres to the document 6, and the lower semi-transparent coating layer 4 is colored, and is displayed as characters and symbols on the document 6 in that color. Is done.

  The seal for preventing forgery of seals of this embodiment has the above laminated structure and is configured as follows. That is, as shown in FIG. 6 (a) or (b), a black halftone dot pattern 18 is applied to the entire surface of the notification mark column 20 in the seal mount 10, and the surface of the film 2 covering the seal mount 10 or The entire back surface is provided with a shielding display 16 such as characters or symbols with reflective ink. In addition, what is shown to Fig.6 (a) is made into a sheet form by providing the adhesive layer in the back surface of the backing paper 10 for printing, and adhering a plurality of sheets to the release paper 8 and arranging them.

  In the above configuration, the black halftone dot pattern 18 applied to the entire surface of the notification mark column 20 on the seal mount 10 is, for example, a mesh of about 80 percent black ink with respect to the entire surface of the notification mark column 20. A dot pattern 18 is applied. The halftone dot pattern 18 is formed by printing fine black dots in a halftone pattern with black ink.

  As shown in FIG. 6B, the film 2 covering the backing paper 10 is a transparent film made of a transparent synthetic resin such as polyethylene terephthalate, as in Example 1. The film 2 has a front surface or a back surface. The entire surface is provided with a shielding display 16 by describing many fine characters (for example, bank names, etc.) or symbols or the like with reflective ink. In addition, what is shown in FIG.6 (b) is made into a sheet form by providing an adhesive layer on the back surface of the film 2 and attaching and arranging a plurality of sheets on the release paper 8.

  In order to use the seal 1 'for preventing stamp forgery of the present embodiment, first, a base seal 19 as shown in FIG. The base seal 19 is a transparent film made of a transparent synthetic resin and has an adhesive on the back surface, and can be adhered to a predetermined portion of the passbook. Next, as shown in FIG. 7B, a stamping mount 10 is pasted on the upper surface of the base seal 19, and a user's notification mark 12 is stamped in a notification mark column 20 with a halftone dot pattern 18. . However, the imprint on the right side of FIG. 6B is a mark 13 to be stamped by the reception staff at the time of collation of the seal.

  Further, when the above-mentioned seal 1 'for preventing forgery of seals is pressure-bonded to the upper surface of the seal mount 10 as described above, as shown in FIG. The screen is covered with a shielding display 16 made of fine characters or the like applied to the entire surface. When the stamping base 10 in this state is enlarged, it becomes as shown in FIG. 8A, and the film 12 forming the seal 1 'can be seen through to visually confirm the imprint 12 below.

  In this embodiment, when carrying over the passbook, by sticking to the base seal 19 attached to the new passbook, the backing paper 10 for peeling off the base seal 19 attached to the old passbook, when carrying over the passbook. It is possible to greatly simplify the work when carrying over the bankbook.

  By the way, when looking at the inside of the imprint 12 shown in FIG. 8A, as shown in FIG. 8B, the vermilion forming the imprint is clearly expressed in the upper part of the black halftone dot pattern 18. When this is scanned by an optical instrument, the vermilion of the imprint is unclearly expressed in white halftone dots other than the fine black halftone dot pattern 18.

  Further, as a test, as shown in FIG. 9 (a), various seals are imprinted on the upper surface of the mount 21 with the black halftone dot pattern 18, and fine characters having reflectivity on the upper surface of the imprint 12 thereof. When the film 2 on which the shielding display 16 is applied is pressed and scanned with an optical device from above, as shown in FIG. 9 (b), the light of the plurality of reflective shielding displays 16 having the reflectivity is shown. Since a defect portion is generated in the imprint 12 due to irregular reflection, it becomes impossible to read the imprint more accurately in combination with the effect of the halftone dot pattern 18 described above.

  Further, in this embodiment, as shown in FIG. 10, when the seal 1 ′ is peeled off from the state in which the seal 1 ′ is pressure-bonded to the upper surface of the imprint 12 imprinted on the printing board 10, the first embodiment is removed. As described in detail above, only the portion of the display layer 3 on which the letters and symbols such as “opened” are displayed on the upper surface of the seal mount 10 is attached to the seal mount 10 by the laminated structure of the seal 1 ′. Then, it is displayed as a color of the translucent coating layer 4 (see FIG. 2B) below the display layer 3, and when this is read with an optical device or the like, the plurality of display layers 3 cover the imprint 12 Since it is reflected, it is possible to prevent forgery of the seal by the seal.

  The present embodiment has been made in order for a user himself / herself to determine a notification seal in response to the widespread use of a bankbook that does not stamp a notification seal. That is, even if the user himself / herself has a notification seal, when a different seal is stamped for each of the plurality of passbooks, the notification seal that matches each passbook may not be known.

  Therefore, although not shown, in the present embodiment, a notification stamp is stamped on a note book to be stored by the user himself, and the forgery prevention of the first or second embodiment is prevented at the stamped portion of the slip book. By crimping the seal, it is possible to visually discriminate the seal stamp possessed by the user and the seal of a predetermined passbook. And even in such a book, a black halftone pattern is applied to the base of the book so that the seal is not forged by the stamp imprinted on the book, and the above-mentioned stamp is also imprinted on the stamp imprinted on the top surface. It is possible to prevent the stamp from being counterfeited by crimping the prevention seal.

  In this embodiment, it is possible to make a book for each passbook, but prepare one booklet and enter the bank name, savings type, account number, etc. for each stamp on the stamp. By providing, it is possible to easily record and save a plurality of seal impressions.

  As described above, the seal for forgery prevention of the present invention attaches the seal to the document so as to cover the seal to be protected so that the seal imprinted on the savings passbook or various certificates is not forged. This makes it possible to use it as a very effective anti-counterfeiting tool for seals.
