FIG. 1E is an enlarged view showing a range in the vicinity of the letter “J” of the large pattern 70.
1D and 1E show the outline of the large pattern 70 with a solid line in order to explain the observation mode of the large pattern 70.
Note that the two-dot chain line in FIGS. 1D and 1E, the solid line of the outline of the large pattern 70, the circle figure describing the minute character 61, and the like are shown for convenience and are not actually formed.
In the embodiment and drawings, an XYZ orthogonal coordinate system is provided for ease of explanation and understanding. This coordinate system represents the left-right direction X (left side X1, right side X2), the vertical direction Y (lower side Y1, upper side Y2), and the thickness direction Z (lower side Z1, upper side Z2) on the basis of the state of FIG. 1A. .
In the drawings, the configuration in the thickness direction Z is exaggerated as appropriate.

As shown in FIGS. 1A and 1B, the card 1 (pattern forming body) is used for a credit card, an identification card, a bank cash card, and the like.
The card 1 includes a substrate 10, a pattern printing layer 20, an upper transparent layer 30, an upper printing layer 31, a lower transparent layer 40, and a lower printing layer 41.
On the upper side Z <b> 2 of the substrate 10, the pattern printing layer 20, the upper transparent layer 30, and the upper printing layer 31 are laminated in this order from the lower side Z <b> 1 to the upper side Z <b> 2. On the lower side Z1 of the base material 10, a lower transparent layer 40 and a lower printed layer 41 are laminated in this order from the upper side Z2 toward the lower side Z1.
The base material 10, the upper transparent layer 30, and the lower transparent layer 40 are formed of a resin sheet such as PET, PET-G, or PVC, or an alloy sheet material of these resins. The upper transparent layer 30 and the lower transparent layer 40 are transparent layers. These layers are joined by heat welding or the like by hot pressing.

The base material 10 is a member that serves as a base of the card 1.
The pattern printing layer 20 is laminated on the base material 10 by performing offset printing using a plate or the like. In a state where the card 1 is observed from the upper side Z <b> 2, the printed content of the pattern print layer 20 is visible through the upper transparent layer 30.
Details of the pattern printing layer 20 will be described later.

The upper print layer 31 is a layer on which, for example, the name 31a of the card 1 is printed. The upper printing layer 31 is laminated on the upper transparent layer 30 by performing offset printing. A transparent protective layer may be provided on the upper side Z2 of the upper printed layer 31 as necessary.
The lower print layer 41 is a print layer similar to the upper print layer 31.

The pattern 50 formed by the pattern print layer 20 will be described in detail with reference to FIGS. 1C to 1E.
Although the pattern 50 demonstrates the example formed in the whole surface on the base material 10 in embodiment, it is not limited to this, You may be formed in a part on the base material 10. FIG. For example, the pattern 50 may not be provided in a range that overlaps characters or the like by the upper printing layer 31.
The print color of the pattern print layer 20 is not limited as long as it can be observed on the substrate 10. For example, when the base material 10 is white, the printing color of the pattern printing layer 20 may be one blue color.

As shown in FIGS. 1C, 1D, and 1E, the pattern 50 includes a minute pattern 60 (first pattern) and a large pattern 70 (second pattern).
The minute pattern 60 includes an array of a plurality of minute characters 61 (first pattern elements). In the embodiment, the minute pattern 60 includes a plurality of character strings “JAPAN” arranged in the vertical direction Y and the horizontal direction X. The minute character 61 is each character of “JAPAN”.
The minute pattern 60 is not limited to the one in which the minute characters 61 are arranged, and for example, the minute pattern 60 may be one in which minute elements such as figures, symbols, and patterns are arranged (a minute element group).
The minute character 61 is called a micro character. The character size of the minute character 61 is about 0.2 mm. For this reason, it is not possible to distinguish each character by the normal magnification observation with the naked eye. The minute character 61 can be identified by, for example, magnifying observation using a magnifying glass such as a loupe.
For this reason, the micropattern 60 is observed as a simple background when observed with the naked eye. As a result, it is difficult for an observer to notice the presence of “JAPAN” of the micropattern 60 at a glance, and the micropattern 60 requires a high printing technique. Thereby, the card | curd 1 can improve the forgery prevention effect.
In addition, when “JAPAN” of the minute pattern 60 is observed by observation with a magnifying glass, an unexpected surprise can be given to the observer.

The micropattern 60 includes two regions, a light line portion 65 and a dark line portion 66.
The density of the line (dark line) of the minute character 61 arranged in the dark line part 66 is darker than the line (light line) of the minute character 61 arranged in the light line part 65. The shades of the characters in the light line portion 65 are uniform at least in the region around the outside of the outline of the large pattern 70.
The dark line portion 66 is a region in the shape of a character string “JAPAN”. A plurality of character strings are arranged in the vertical direction Y and the horizontal direction X.

As shown in FIG. 1E, the large pattern 70 is a character pattern formed by the dark line portion 66. That is, the large pattern 70 is a pattern expressed by observing the areas of the light line portion 65 and the dark line portion 66 of the micro pattern 60 as different areas and identifying the outer shape of the area of the dark line portion 66. is there. The character shape of “JAPAN” in the large pattern 70 is an area of the dark line portion 66.
Each character of “JAPAN” in the large pattern 70 has a character size larger than the minute character 61 in “JAPAN” of the minute pattern 60. For example, when the character size of the minute character 61 is 0.25 mm, the large pattern 70 The character size of can be about 1 mm. The size of the character string “JAPAN” in the large pattern 70 is, for example, a length in the horizontal direction X × a length in the vertical direction Y is about 4 mm × 1 mm. For this reason, the character “JAPAN” of the large pattern 70 can be discriminated by equal-magnification observation with the naked eye.
The size of “JAPAN” of the large pattern 70, the size of the minute character 61, and the like can be set as appropriate. For example, the size, character spacing, and the like of the minute characters 61 can be set as appropriate so that the characters “JAPAN” in the large pattern 70 can be easily identified.

The minute character 61 arranged so as to straddle the outline of “JAPAN” of the large pattern 70 (that is, the boundary 67 of the light line portion 65 and the dark line portion 66) is a light line portion 65, Both dark line portions 66 are provided.
For example, as shown in FIG. 1E, “N”, which is one minute character 61 a, includes a light line portion 65 and a dark line portion 66 with the outline of the large pattern 70 as a boundary 67. In FIG. 1E, the light line portion 65 is illustrated using a contour line and hatching. However, in reality, the light line portion 65 does not include a contour line and is filled with a light color.
As described above, one minute character 61 includes both the light line portion 65 and the dark line portion 66, and as described above, the light and shade of the minute character 61 in the light line portion 65 is around the outside of the large pattern 70. It is uniform in the area. Thereby, the card 1 can express the outline of the characters “JAPAN” of the large pattern 70 more sharply.

In addition, since one minute character 61 includes both the light line portion 65 and the dark line portion 66 in this way, printing of the pattern 50 requires printing by a plate, and more advanced printing technology. Therefore, the anti-spoofing effect can be further improved.
Furthermore, since the minute characters 61 can be arranged across the outline of the large pattern 70, the degree of freedom of arrangement of “JAPAN” of the large pattern 70 can be improved.

  As described above, the pattern 50 of the card 1 according to the present embodiment can observe “JAPAN” of the large pattern 70 by observation with the naked eye. On the other hand, “JAPAN” of the minute pattern 60 can be observed by observation with a magnifier. Moreover, since the forgery prevention effect can be improved, security can be improved.

(Second Embodiment)
Next, a second embodiment of the present invention will be described.
In the following description and drawings, parts having the same functions as those of the first embodiment described above are given the same reference numerals or the same reference numerals at the end (the last two digits), and overlapping explanations are appropriately given. Omitted.
FIG. 2 is an enlarged view (a diagram corresponding to FIG. 1E) showing a range in the vicinity of the letter “J” of the large card pattern 270 of the second embodiment.
The other range of the card (the range other than “J” of “JAPAN” of the large pattern 270) is formed in the same manner as in FIG.
The minute pattern 260 includes two regions, a light line portion 265 and a dark line portion 266. The large pattern 270 is a character pattern formed by the dark line portion 266. In the second embodiment, the thickness L265 of the minute pattern 260 in the region of the light line portion 265 is formed to be thinner than the thickness L266 of the minute pattern 260 in the region of the dark line portion 266. For example, the thickness L265 of the micropattern 260 in the area of the light line portion 265 is 0.02 to 0.04 mm, and the thickness L266 of the micropattern 260 in the area of the dark line portion 266 is 0.04 to 0.08 mm. Can do.
For this reason, in the card of this embodiment, the outline of the characters of the large pattern 270 becomes clear, and the large pattern 270 can be expressed more sharply.
Note that only the minute characters 261 arranged on the outline of the large pattern 270, that is, the minute characters 261 arranged across the outline of the large pattern 270 and having both the light line portion 265 and the dark line portion 266 in one character. The same effect can be obtained by forming the thin line portion 265 with a small thickness and the dark line portion 266 with a large thickness.

(Third embodiment)
Next, a third embodiment of the present invention will be described.
In the following description and drawings, parts having the same functions as those of the first embodiment described above are given the same reference numerals or the same reference numerals at the end (the last two digits), and overlapping explanations are appropriately given. Omitted.
FIG. 3 is an enlarged view (a diagram corresponding to FIG. 1E) showing a range in the vicinity of the letter “J” of the large card pattern 370 of the third embodiment.
The other range of the card (the range other than the characters “JAPAN” of the large pattern 370) is formed in the same manner as in FIG.

The first minute pattern (first pattern) 360 is formed by a thin line. The first minute pattern 360 is formed in the same manner as the minute pattern 60 of the first embodiment in a range other than the characters “JAPAN” of the large pattern 370. Similarly to the micropattern 60 of the first embodiment, the first microcharacters (first pattern elements) 361 are arranged to represent the characters “JAPAN”.
However, the first micropattern 360 is different from the micropattern 60 of the first embodiment in that the first micropattern 360 is not formed in the range of each character of “JAPAN” of the large pattern 370.

The large pattern (second pattern) 370 is a character pattern formed by a collection of second minute patterns 380 formed by dark lines. The second minute pattern 380 represents a character string “JPA” by arranging second minute characters (second pattern elements). Similar to the first micropattern 360, a plurality of the second micropatterns 380 are arranged in the vertical direction Y and the left-right direction X.
As shown in FIG. 3, the second minute character 381 in the third embodiment uses a smaller character than the first minute character 361. However, the second minute character 381 may be a character of the same size, or conversely a larger character. It is good. Further, the thickness of the second minute character 381 may be different from that of the first minute character 361 as in the second embodiment.

(Fourth embodiment)
Next, a fourth embodiment of the present invention will be described.
In the following description and drawings, parts having the same functions as those of the first embodiment described above are given the same reference numerals or the same reference numerals at the end (the last two digits), and overlapping explanations are appropriately given. Omitted.
FIG. 4 is a diagram corresponding to FIG. 1C of the first embodiment, and is a diagram for explaining the pattern 450.
FIG. 5 is a diagram corresponding to FIG. 1D of the first embodiment, and shows a range of one large pattern 470 (that is, a set of characters “JPN”).

In the fourth embodiment, as shown in FIGS. 4 and 5, the character string of the minute pattern 260 is “JAPAN” as in the first embodiment, and the character string of the large pattern 270 is the same as that of the first embodiment. Are different "JPN".
As in the present embodiment, by making the words of the large pattern 470 and the minute pattern 460 relevant words, it is possible to determine a case where they are not relevant to each other as a counterfeit product, and to prevent forgery. Further improvement can be achieved.
Here, the related words are the same as in the case of “JAPAN” and “JPN”, for example, when one is an abbreviation, or “JAPAN” and “Japan”. This is the case where the meaning of is expressed in a different language.
In the present embodiment, the character string of the minute pattern 260 is “JAPAN” and the character string of the large pattern 270 is “JPN”, but this may be reversed. That is, the character string of the minute pattern may be “JPN”, and the character string of the large pattern may be “JAPAN”.

  As mentioned above, although embodiment of this invention was described, this invention is not limited to embodiment mentioned above, For example, various deformation | transformation and a change are possible like the deformation | transformation form etc. which are mentioned later, These are also It is within the technical scope of the present invention.
