2. Description of the Related Art Banknotes, passports, securities, cards,
Due to their properties, valuable printed materials such as stamps are required to be hard to forge or falsify. As a preventive measure for this, there are known, for example, a clearance, a fine image configuration, intaglio printing, and the like. At the same time, since these valuable printed materials need to be authenticated or otherwise processed by a machine, they need to be provided with a machine reading element. For this reason, a method of mixing special substances into the ink,
A method of coating or mixing a special substance on a base material such as paper is used.

[0003] In some cases, such as the Swiss 200 franc, letters or numbers are represented by a perforated arrangement. Further, there is also an example in which a grayscale image of a portrait is binarized, and a portrait is expressed based on binarized data expressing grayscale.

[0004]

However, among such anti-counterfeiting means, since the pit can be artificially produced with a varnish or the like, it is difficult to provide a complete anti-counterfeiting means. In addition, since a fine image configuration or the like can be almost reproduced by a color copying machine, it is becoming difficult to easily determine the authenticity. Even in intaglio,
Giving sufficient finger sensibility requires a large area, which causes many problems in design.

[0005] Ink used for machine reading of valuable printed matter is typically magnetic ink used for banknotes. However, from the viewpoint of distribution, the permissible range of authenticity determination is wide and complete ink is used. At present, it cannot be a true / false decision element. Furthermore, in the case of Swiss 200 franc, forgery and alteration are possible by piercing by imitating the piercing arrangement, and the shading is 2
Converted to quantified data, the drilling position,
That is, means for expressing a portrait by converting to coordinates x and y is as follows.
The configuration is complicated, and the determination of the authenticity is not always easy.

[0006] In recent years, the development of precision processing technology for fine perforation of paper, film, metal plate, etc. has been remarkable.
For example, the processing technology of micro-perforation using a laser is capable of easily arbitrarily arranging perforations, and generates much less burrs at the time of perforation than a mechanical perforation with a needle for forgery or falsification.

DESCRIPTION OF THE PREFERRED EMBODIMENTS Embodiments of the present invention according to the present invention will be described based on embodiments with reference to the drawings. The present invention relates to an authenticity discriminating body and an authenticity discriminating apparatus. When the authenticity discriminating forming body is overlaid on a color element screen serving as an authenticity discriminating apparatus, a visual observation provided to the authenticity discriminating forming body By being able to see pattern information (characters, figures, patterns, etc.) composed of fine laser perforations that cannot be recognized by
It is characterized in that authenticity can be determined.

The color element screen includes a liquid crystal panel, a CRT,
There are various forms such as a print screen, and a color element exhibiting any one of a plurality of colors is formed by repeating an arrangement in a predetermined pitch and in a predetermined order. The plurality of colors include, for example, RGB (red, green, blue), YCM (yellow, cyan, magenta), black and white, and various other combinations of a plurality of colors. Further, there are color stripes, dots, halftone dots, and the like, which are arranged as color elements at a constant pitch.

(Embodiment 1) FIG. 1 is a diagram for explaining an embodiment of the present invention. True / false discrimination forming body 1 shown in FIG.
Is superimposed on the screen of the liquid crystal panel 2 used as the color element screen shown in FIG. 1B, as shown in FIG.
The pattern information 3 (characters or figures) formed by fine perforations which are provided to the authenticity discriminating formed body 1 but cannot be visually recognized can be visually checked, thereby enabling the authenticity discriminating formed body 1 to be authenticated. It is characterized by becoming.

In the first embodiment, the liquid crystal panel 2 is used as a color element screen of the authenticity discriminating apparatus.
May be a dedicated machine as will be described later, but may be a general machine widely used for office and home use.

As shown in FIG. 1B, the liquid crystal panel 2 uses, as color elements, stripes 4 (liquid crystal panel striped color filters) of a constant width w extending in the vertical direction of RGB (red, green, blue). The stripes 4 are arranged at a constant pitch p in the horizontal direction, and are arranged in a predetermined order to form a color element screen (a screen having color elements forming a color image).

The authenticity discriminating formed body 1 has a base material 6 on which a number of fine perforations 7 are formed by laser. This perforation 7 is a fine perforation that cannot be visually recognized, but is a perforation for providing pattern information. In the first embodiment, as shown in FIG.
Are formed so as to define the character information 8 "JPT". In FIG. 1 (a), the outline is shown by an imaginary line A with a small number of perforations for the sake of explanation. However, pattern information such as characters and figures is actually defined by a large number of perforations.

In the first embodiment, the pattern information provided to the authenticity discriminating body composed of a large number of perforations 7 includes a perforation group 9 representing the information element "J" and a perforation group 1 representing the information element "P".
0, a group of perforations 11 representing the information element “T”.

The width of the perforations 7 is smaller than the width w of the stripe. A large number of perforations 7 are provided in each of the perforation groups 9 to 11 with a pitch (3 × 3) that is three times the pitch p of the RGB stripes 4 of the liquid crystal panel in the horizontal direction.
p) and a vertical pitch p ′. In general terms, the fine perforations are formed in the horizontal direction at a pitch of [the number of colors of a plurality of color elements] × [the width of the color elements in the horizontal direction].

Therefore, the authenticity determining forming body 1 is connected to the liquid crystal panel 2
Overlaid, perforations 7 in the same perforation group for perforation groups 9-11 correspond to any one of the same color stripes 4 of RGB, so that the same perforation for perforation groups 9-11 The perforations 7 in the group can all be seen through the same color, and the perforation group can be observed by developing any one of RGB colors.

For example, in the first embodiment, as shown in FIG. 1 (c), all the perforations of the perforation group 9 representing "J" correspond to the B (blue) stripes, appear blue, and represent the perforations representing "P". Group 10
All perforations correspond to the R (red) stripe and look red,
All the perforations of the perforation group 11 representing "P" correspond to G (green) stripes and appear green.

The distance between the perforations of the perforations 9 to 10 (the distance between the closest perforations of the different perforations) is 3p × n + p × m in the first embodiment. You. Here, n is an integer of 1 or more, and m indicates the degree of deviation of the pitch between the perforation groups, and is 0, 1, or 2.

With respect to the two perforation groups, when m = 0, there is no shift in pitch and the corresponding stripes have the same color (eg, R and R), and when m = 1, the pitch is shifted by one. The colors are adjacent to each other (R and G). When m = 2, the pitches are shifted by two, so that the colors are separated by one color (eg, R and B).

[0036] With regard to FIG. 1 (a), spacing D ₁ of the and the "J", "P" is computed by n = 2, m = 1, the color of the adjacent stripe (G and R) to each other . or,
The distance D ₂ between “J” and “T” is calculated with n = 5 and m = 2, and colors separated by one color (R color) (eg, B)
And G).

As described above, the degree of pitch shift m between the different perforation groups is determined by the information element (eg.
J, P, and T) may be selected according to the color to be provided and perforated.

The distance D ₂ between the perforation groups related to the color difference between the above-mentioned different perforation groups is generally expressed as m = [0
To any number of (the number of colors of a plurality of color elements −1)], and the interval D between the perforation groups = [the number of colors of a plurality of color elements] ×
[The horizontal pitch p of the color element] ± [any number of 0 to (the number of colors of a plurality of color elements−1)] × [the horizontal pitch p of the color element].

The authenticity discriminating body 1 having such a configuration
The operation of will be described. Now, when the authenticity determination forming body 1 is overlaid on the liquid crystal panel 2 functioning as the color element screen 5, FIG.
As shown in (c), the perforations of “J” overlap on the B (blue) stripe and the B color is seen through the perforations, and the perforations of “P” overlap on the R (red) stripe and R through the perforations.
The color is visible and the “T” perforations overlap the G (green) stripe and the G color is visible through the perforations.

As a result, the authenticity discriminating body 1 can be imagined as if "J" is colored (colored), "P" is colored R, and "T" is colored G. The entire character information 8 "JPT" as indicated by the line B is raised and can be viewed.

The forged authenticity discriminating body 1 having no perforation as in the present invention does not show any pattern information such as characters, figures and patterns even when viewed on the liquid crystal panel 2.
Also, in the case of a forged or forged authenticity discriminating formed body in which a perforation is formed but not provided with a true perforation, even if it is overlaid on the liquid crystal panel 2, it is colored B, R, and G, respectively. Since the authentic pattern information “JPT” cannot be recognized, the authenticity can be determined.

When the perforated rows of the authenticity discriminating body 1 are not parallel to the RGB stripes 4 of the liquid crystal panel 2, or the pitch p of the perforations 7 is three times the pitch p of the RGB stripes 4 and completely equal to one. Otherwise, the emission colors passing through the perforations 7 are not the same over the entire surface.
Iris moire of color occurs.

Then, the liquid crystal panel 2 and the authenticity determination forming body 1
When there is a glass or a gap between the stripes, the color of the stripes 4 may be different depending on the viewing angle, so that the color of the moire also changes. If the boring arrangement of the authenticity discriminating formed body 1 is completely random, such RGB
Since moiré of three colors does not occur, it is possible to roughly determine whether the moiré has occurred or not.

Here, the first embodiment will be described in more detail with a specific example. The width w of the RGB stripes 4 of the liquid crystal panel 2 varies depending on the model. For example, each width of the stripe 4 is set to 0.1 mm.

On the other hand, when examining the perforation shape of the perforations 7 of the authenticity discriminating formed body 1, the short diameter (horizontal width) of the perforations 7 can be recognized in a single color in consideration of the RGB stripe width. In this case, the width is set to 0.1 mm, which is almost the same as the width w of the RGB stripe.

By the way, as shown in FIG. 2, the short diameter (width) of the perforations 7 is made larger than the width of the RGB stripes 4 so that the perforations of the authenticity discriminating formation 1 straddle a plurality of colors of the RGB stripes 4. Then, the mixed color may be transmitted and recognized.

In this case, as shown in FIG.
If the three colors of the stripes are completely straddled, they can be seen as white light and cannot be identified. Therefore, in the case of the three colors, the two colors are straddled as perforations 13 or the three colors are completely straddled as perforations 14. You need to do that. Preferably, the minor axis (lateral width) of each of the perforations is at most a dimension of [the width w of the stripe] × [the number of colors of the color element screen−1] or less.

By the way, the shape of the perforations 7 may be basically any shape. Considering appropriate dimensions, the longer the diameter or side parallel to the RGB stripe is, the easier it is to recognize. If the length is too long, the strength of the base material becomes weak and a large area is required. Considering these, the following perforated shapes are considered appropriate. A circle with a piercing diameter of 0.1 mm to 0.2 mm A minor diameter of 0.1 mm to 0.2 mm, a major diameter of 0.25 mm to 1
mm ellipse Short side 0.1mm ~ 0.2mm, Long side 0.25mm ~ 1
mm square

FIG. 3 is a diagram for explaining a modification of the first embodiment. In the first embodiment, the character information “JPT” is described as the pattern information to be provided to the image forming body. However, the present invention can be applied to a figure or a pattern as the pattern information.

True / false discrimination forming body 20 provided with figures, patterns, etc.
In the case of, perforation groups 9-1 for each information element of J, P, T
A figure or pattern, for example, as shown in FIG.
Square information 15 as shown in (square pattern information)
Is 3 × p (where p is the pitch of the stripe) so as to correspond to any one of the desired RGB stripes 4 in each of the four divided regions 16 to 19 as indicated by imaginary lines.
The holes are pierced at intervals determined by.

The authenticity judgment forming body 20 having such a configuration is
By superimposing on the liquid crystal panel 2 shown in FIG.
As shown in FIG. 3 (c), within one piece of square information 15,
RGB colors are observed for each region. By taking this one step further and performing perforation so as to correspond to a stripe of a desired color for each perforation, it becomes possible to observe a figure or pattern as a whole in a complicatedly colored state.

(Embodiment 2) FIG. 4 is a view showing Embodiment 2 of the authenticity determining body according to the present invention. The authenticity discriminating formed body 21 of the second embodiment has a fine hole 7 formed in the base material 6 so as not to be visible with a laser, and has the same basic structure as the authenticity discriminating formed body 1 of the first embodiment. However, the feature is that an array of perforations other than the partially fine perforations 7 is formed and secondary information is added.

The secondary information is used to determine whether the authenticity determining body 21 is
A secondary information perforation 22 having a large perforation diameter, such as a secondary information perforation 22 having a large perforation diameter, is formed so as to be easily recognizable visually even when observed alone without being superimposed on the liquid crystal panel 2, as shown by an imaginary line c in FIG. Secondary information such as the letter “C” is added.

The operation of the second embodiment will be described. As described above, the authenticity determination forming body 21 can recognize the secondary information perforation 22 but cannot recognize the information T provided by the perforation 7 when observed alone.

However, when the authenticity discriminating body 21 is superimposed on the screen of the liquid crystal panel 2, as shown in FIG. 2C, a part of the information perforation 7 overlaps the B (blue) stripe. ,
Another part of the fine perforation 7 and the secondary information perforation 22 is R
It overlaps the (red) color stripe. As a result, FIG.
(C) As shown in FIG.
And the secondary information perforation 22 is colored in R color, the character information T of R color is more prominently recognized than the secondary information C, and the secondary information C
However, if you are not conscious of it, you will not be able to recognize it.

Therefore, even if the authenticity discriminating formed body is observed without recognizing the secondary information C without being superimposed on the liquid crystal panel 2, the forged or altered authenticity discriminating formed body is superimposed on the liquid crystal panel 2. By observing, it is possible to easily determine that the formed body 21 is not the true authenticity determination forming body 21.

FIG. 5 shows a truth discrimination forming body 23 showing a modification of the second embodiment. Square information 24 which is pattern information
Are formed at a pitch of 3 × p (where p
Are formed at the pitch of the RGB stripe 4).
As shown in FIG. 5 (a), a small perforation 7 is formed inside the square information 24 so as to be invisible, but the perforation in a region defining a circle indicated by an imaginary line E is a secondary of a large size. It is formed as an information perforation 25 and is configured by adding circular secondary information as a whole.

In the circular secondary information, since the size of the secondary information perforation 25 constituting the circular information is large, even when the authenticity discriminating formed body is observed on the liquid crystal panel 2 without being superimposed, the circular figure is visually observed. Can be recognized. However, when the authenticity discriminating formed body is observed over the liquid crystal panel 2 shown in FIG. 5B, as shown in FIG. 5C, the perforations 7 and 2 forming the square information 24 of the pattern information are obtained. Next information piercing 25 is R
Since it is placed on the color stripe, R
The color square pattern information can be observed, and the circular secondary information is not particularly noticeable and cannot be recognized.

(Embodiment 3) Since the authenticity discriminating body according to the present invention can recognize the perforation by using a general liquid crystal panel used for a personal computer or the like marketed for office use or home use. For example, it is extremely versatile and useful, for example, for checking a card in the distribution industry (supermarket cash register). However, since the width and pitch of the RGB stripes of the liquid crystal panel used in commercially available personal computers and the like vary depending on the model, it has been confirmed that one authenticity determination forming body cannot cope with the difference.

Taking advantage of this point, a third embodiment of the authenticity discriminating body according to the present invention is to fabricate a liquid crystal panel dedicated to authenticity discrimination (not shown) and discriminate it from a general liquid crystal panel. And a hole is formed in accordance with the RGB stripe of the liquid crystal. According to the third embodiment, it is possible to make it impossible to recognize perforations even by using a general liquid crystal panel, and to make it impossible to analyze characteristics such as the shape, pitch, and perforation position of perforations.

(Embodiment 4) FIG. 6 shows Embodiment 4 of the present invention.
FIG. 6A is a diagram for explaining (FIG. 6A) and Example 5 (FIG. 6B). Embodiments 4 and 5 both use a printed material as a color element screen instead of a liquid crystal panel as an authenticity determination device. In Example 4, as shown in FIG. 6A, a transparent film 26 was formed using YCM color ink.
Next, the color element screen is formed by printing the YCM stripe 27 as a color element in accordance with the shape of the perforations 7 and the perforation pitch of the authenticity determination forming body 1.

The authenticity discriminating formed body 1 is superimposed on the transparent film 26, and the transparent film 26 is illuminated with a backlight 28. The transmitted light allows the information given by the perforations 7 to be recognized. Note that the same effect can be obtained by using, as a color element screen, a sheet obtained by printing a YCM stripe 27 on a sheet having a transmission light amount equivalent to that of a copy sheet.

Example 5 In Example 5, instead of a liquid crystal panel, a YCM stripe 30 was printed on the surface of a substrate 29 using fluorescent ink as shown in FIG. This is used as a color element screen. On the substrate 29, the stripes of the YCM cannot be seen under normal sunlight and white light, but when irradiated with ultraviolet light,
The M stripe 30 is colored.

When using the fifth embodiment, the authenticity discriminating body 1 is overlaid on the substrate 29, and ultraviolet light is irradiated from above on the substrate 29 by the ultraviolet lamp 31. Then, the ultraviolet light is irradiated to the YCM stripe 32 of the fluorescent ink through the perforations 7,
By exciting this, excitation light 33 of YCM is generated. From the excitation light 33, information can be recognized through the perforation 7, and the authenticity of the authenticity determination formed body can be identified.

(Embodiment 6) In Embodiment 6 according to the present invention, when information is recognized by superimposing a true / false discrimination forming body on a color of a liquid crystal panel or the like, machine recognition is performed instead of visual observation. . In the sixth embodiment, an image obtained by superimposing the authenticity determination forming body on the color is photographed by a CCD color camera to obtain an original image. Then, the original image is color-separated and RG
The density value is measured for each B, and image data for each RGB is obtained.

As a result, the emission color from the color passing through the perforation is, for example, R, and the image data can be recognized as a pattern by pattern recognition.

Although the present invention has been described with reference to the embodiments, it is not limited to these embodiments. It goes without saying that various other embodiments and examples are conceivable within the scope of the claims.
