EMBODIMENT OF THE INVENTION Hereinafter, preferred embodiment of this invention is described with reference to an accompanying drawing.

1 is a block diagram showing an embodiment of a card to which the present invention is applied. In Fig. 1, the side edge portion (card edge) 10a of the card 10 as a data recording medium formed in a rectangle made of paper, plastic, or the like is colored and separated into a colorless ultraviolet light-emitting ink (UV ink) as shown. The first layer 11 formed by printing the first code pattern and the second layer 12 formed by printing the second code pattern by colorless infrared absorption ink (IR ink) are provided. In addition, the first and second code patterns are printed by overlapping the entire portions as shown in the drawing, and in addition, the first and second code patterns are overlapped and printed as necessary in consideration of the length of the code pattern, the size and the area of the recording portion, and the like. You may comprise so that.

Moreover, you may change the order of the 1st layer 11 and the 2nd layer 12, and may increase the number of layers further. Also in this case, printing is performed using ink having different properties so that the detection method of each layer is different. By increasing the layer, the amount of data that can be recorded increases, and the kind of data that can be used for ID or the like can be increased, and forgery becomes more difficult. In addition, the first layer 11, the second layer 12, and the like formed by overlapping printing at the same position are used as a printing layer group for one unit, and such a printed layer group is used for each part (side edge portion) of the card 10. FIG. Long side, short side, card surface, etc.) may be provided in plurality. As a result, the amount of data that can be recorded can be further increased, and the type of data that can be used for ID can be increased.

In the above embodiment, the ultraviolet light emitting ink and the infrared absorption ink are used in combination as the paint, but other paints may be used in combination. Types of paint include "infrared rays", "ultraviolet rays", etc. as light regions, and "absorption", "reflection", "luminescence" (in addition, "luminescence" means that the emission color is fixed regardless of the wavelength of the irradiation light. The emission color may differ depending on the wavelength of the irradiation light), and a combination of these may be considered. For example, in addition to the above-mentioned ultraviolet light emitting ink and infrared absorbing ink, a light reflective ink reflecting only light of a specific wavelength, a light emitting ink emitting light only in response to light of a specific wavelength, and a wavelength in response to light of a specific wavelength The light emitting ink which emits light of a different color, the light absorbing ink which absorbs only light of a specific wavelength, not limited to infrared rays, etc. can be used. On the other hand, the coating application to each layer to be superimposed and printed is combined, and the case of using a heterogeneous paint as in the above-mentioned embodiment, and the same kind of paint, but the wavelength of the light to react may be different. Examples of the use of the same kind of paint include the use of a plurality of infrared absorption inks having different wavelengths for absorption, the use of light absorbing inks having different wavelengths than the infrared absorption ink, respectively. It is possible. In addition, not only printing by paint which reacts to light, but also other recording methods (magnetic or the like) having different detection methods may be used.

FIG. 2 is a view showing the ultraviolet light emitting ink used for the first layer 11, and the star-shaped pattern 13 is typically formed on the surface of the card not on the side edge portion as shown in (a). In this case, when only ultraviolet light is irradiated, only the portion of the pattern 13 is emitted as shown in (b), and the other portions appear dark. When only normal visible light is irradiated, nothing is seen as shown in (c).

On the other hand, Figure 3 is a view showing the infrared absorption ink, and as shown in (a) is a schematic depiction of the star-shaped pattern 14 on the card surface rather than the side edge portion as the infrared absorption ink, in this case When only the infrared light is irradiated, only the pattern 14 part appears dark as shown in (b), and the other part appears bright by reflection. When only normal visible light is irradiated, nothing is seen as shown in (c).

4 is a view showing a code pattern seen by the card 10 shown in FIG. In the case of a true card, only the code pattern of the first layer 11 is visible when only ultraviolet light is irradiated, and only the code pattern of the second layer 12 is visible when only the infrared light is irradiated. The case seems nothing.

Fig. 5 is a view of code patterns of a calm card printed with infrared absorption ink and ultraviolet light emitting ink, respectively, and these are seen by irradiation of infrared light and ultraviolet light, and the respective code patterns are shown without interfering with each other. This makes it possible to identify the respective recorded contents by printing and recording codes of different contents without interfering with each other in the same place on the card and irradiating infrared light and ultraviolet light.

In this way, the first layer 11 formed by printing the first code pattern and the second layer 12 formed by printing the second code pattern are superimposed so that data can be written even in a narrow area. You can increase the amount. In addition, since a plurality of printing materials are used in a narrow area to overlap codes of different contents, it is difficult to obtain printing materials, and it is difficult to accurately reproduce by hand using the same as a genuine card. Can be effectively prevented. In addition, in the case of a card used in the game apparatus, the combination of the first code pattern and the second code pattern is recognized as card-specific data (for example, ID data), and the progress of the game is performed in accordance with the card-specific data. Will be done.

In the embodiment of Figs. 1 to 5, the case where the different kinds of paints by the ultraviolet light emitting ink and the infrared absorption ink were used for the first layer 11 and the second layer 12 was explained. It is also possible to use a plurality of infrared absorbing inks each having a different absorbing wavelength.

FIG. 6 shows an example of an infrared absorption spectrum of an infrared absorption ink, in which an infrared absorption ink IR1 having an absorption peak at wavelength λ1 and an infrared absorption ink IR2 having an absorption peak at wavelength λ2 are used, and the first layer of FIG. Infrared absorption ink IR1 may be applied to (11), and infrared absorption ink IR2 may be applied to the second layer 12. Of course, you may reverse the application relationship. In addition, instead of the infrared absorption ink each having one absorption peak as shown in FIG. 6, one infrared absorption ink includes the absorption peak of the other infrared absorption ink, for example, the infrared absorption ink IR1 It may have an absorption peak at the wavelength λ1 and the wavelength λ2, and the infrared absorption ink IR2 may have an absorption peak at the wavelength λ2. In this case, only the code pattern using infrared absorption ink IR1 is visible when irradiating infrared light of wavelength λ1, and the code pattern of both infrared absorption ink IR1 and infrared absorption ink IR2 is visible when irradiating infrared light of wavelength λ2. .

FIG. 7 is a view showing the code pattern of the card 10 when the infrared absorption ink of the characteristic shown in FIG. 6 is used. In the case of a true card, only the infrared ray having the wavelength lambda 1 is irradiated with the first layer 11. Only the code pattern of) is visible, only the code pattern of the second layer 12 is visible when irradiating only the infrared light of wavelength lambda 2, and nothing is visible when only the visible light is irradiated. Fig. 8 is a view showing code patterns printed with infrared absorption inks having different absorption wavelengths of a true card and infrared rays having different wavelengths, and the respective code patterns appear without interfering with each other. This makes it possible to identify the respective recorded contents by printing and recording codes of different contents that do not interfere with each other at the same place on the card and irradiating infrared light having different wavelengths.

As described above, by using a plurality of infrared absorbing inks having different wavelengths, which are respectively absorbed as the same kind of paint, forgery can be made more difficult because the specific difficulty of the wavelength is further added to the infrared absorbing ink which is difficult to obtain.

Fig. 9 is a configuration diagram showing another embodiment of the card to which the present invention is applied, wherein (a) is a perspective view of the entire card, and (b) is an exploded view of a code pattern portion. In the above embodiment, the first layer 11 for forming the first code pattern and the second layer 12 for forming the second code pattern are formed on a part of the surface of the card 10 and not on the side edge portion of the card 10. Overprinted. Even in this case, the first and second code patterns may be printed by overlapping the entire portion as shown in the drawing, and in addition to the portions of the first and second code patterns in consideration of the length of the code pattern, the size and the area of the recording portion, and the like. You may comprise. In addition, the code pattern is not limited to the illustrated one, and two-dimensional code or other code patterns may be used. In addition, the number of layers in which the code pattern is recorded may be increased, and in this case, printing is performed using ink having different properties so that the detection method of each layer is different.

Further, as shown in FIG. 10, the first layer 11, 12 or the like formed by overlapping printing at the same position is a unit of print layer, and as shown in FIG. It is also possible to provide a plurality of parts at each part (each part of the card surface, a long side, a short side, etc.) of the card surface. As a result, the amount of data that can be recorded can be further increased, and the type of data that can be used for ID or the like can be increased.

Furthermore, as shown in FIG. 11, the 3rd layer 15 formed with the visible ink is formed on the 1st layer 11, the 2nd layer 12, etc. of the card 10 of FIG. 9 or FIG. You may. In this case, the third layer 15 is made to print a picture or the like, so that the first layer 11 and the second layer 12 and the like below are hard to see with the naked eye, making forgery more difficult. Can be. In addition, by including a meaningful third code pattern in the third layer 15 so as to recognize the combination of the first to third code patterns on the side of the game device, the amount of information per unit area can be further increased. Can make forgery more difficult.

This is superimposed and printed. Also in this case, the first and second code patterns are configured to overlap and print the entire portions as shown in the drawing, and to overlap and print the portions as necessary in consideration of the length of the code pattern, the size and the area of the recording portion. You may also The number of layers in which the code pattern is recorded may be further increased, and printing is performed using ink having different properties so that the detection method of each layer is different. In addition, the code pattern 23 is not limited to what is shown in figure. In addition, by forming the cord pattern 23 into a seal shape and adhering to the rear surface of the mount 21, the manufacture can be facilitated.

It becomes an LED and irradiates infrared light of a corresponding different wavelength, respectively.

FIG. 18 is a flowchart showing the counterfeit detection process in the reading apparatus, and the operation will be described below with reference to FIG.

When the card to be read is loaded and processing is started (step S101), first, the ultraviolet light LED 143 of the read light irradiation unit 141 is turned on (step S102), and the camera 145 shoots ( Step S103), the ultraviolet light LED 143 is turned off (step S104). Then, the image processing apparatus 146 judges whether the code pattern matches the regular format from the photographed image (step S105), and if it does not match the normal format, considers it as a fake card (step S114), and ends the processing. (Step S116).

On the other hand, when the photographing result by the ultraviolet light matches the regular format, the visible light LED 142 of the read light irradiation section 141 is then turned on (step S106), and photographing is performed by the camera 145 (step S107). The visible light LED 142 is turned off (step S108). Then, the image processing apparatus 146 judges whether the code pattern matches the regular format from the photographed image (step S109), and if it does not match the normal format, considers it as a fake card (step S114), and ends the processing. (Step S116).

On the other hand, when the photographing result by the visible light conforms to the regular format, the infrared light LED 144 of the read light irradiation section 141 is then turned on (step S110), and photographing is performed by the camera 145 (step S111). Infrared light LED 144 is turned off (step S112). Then, the image processing apparatus 146 judges whether the code pattern matches the regular format from the photographed image (step S113), and if it does not match the regular format, considers it as a fake card (step S114), and ends the processing. (Step S116). When the photographing result by the infrared light matches the regular format, the card is regarded as a true card (step S115), and the processing ends (step S116).

By the above process, a true card and a counterfeit card can be distinguished correctly. In addition, although imaging | photography and determination are performed in order of ultraviolet light, visible light, and infrared light in FIG. 18, you may change these order.

19 and 20 show a configuration example for generating code pattern data corresponding to a code pattern printed or adhered to a card or the like. As the first code pattern data and the second code pattern data, one-dimensional code (bar code) or 2 There are cases where the numerical value corresponds to the bit string corresponding to the dimensional code, and the equations of the straight line and the curve corresponding to the two-dimensional figure. In the case of a code pattern attached to the side edge portion 10a of the card 10 as shown in Fig. 1, a one-dimensional code based on a numerical value-based bit string is suitable, and the surface of the card 10 as shown in Fig. 9 is suitable. In the case of the code pattern attached to the figure, a two-dimensional code based on a numerical value-based bit string or a two-dimensional figure based on a formula of a straight line or a curve can be applied. Of course, one-dimensional code may be applied to the surface of the card 10.

In Fig. 19, the numerical value or expression of the first code pattern data is converted by using the equation (function) in the conversion section 31 to obtain the numerical value or expression of the second code pattern data. Here, when the second code pattern data is a numerical value, the numerical value of the second code pattern data can be obtained by applying an appropriate function to the numerical value of the first code pattern data or the coefficient of the equation. When the second code pattern data is an expression, one or more lines of mathematical expressions (straight and curved lines) are calculated by performing calculations on the numerical values of the first code pattern data or the coefficients of the expressions and substituting the coefficients of the equations representing the straight lines or curves. By deriving uniquely, the second code pattern data can be obtained.

In FIG. 20, the pre-conversion unit 32 is provided in front of the above-described conversion unit 31, and the conversion unit (based on the conversion unit (based on the conversion or encryption table) is performed on the coefficient of the numerical value or expression of the first code pattern data. 31), second code pattern data is obtained. As a result, it is possible to further decipher the relationship between the first code pattern data and the second code pattern data.

FIG. 21 shows an example of a code pattern attached to the surface of the card 10. (a) shows that the code pattern of the first layer 11 is a one-dimensional code based on a numerical value based bit string, and is overlaid and printed. The second layer 12 is formed as a two-dimensional figure by a mathematical expression converted from the numerical value of the code pattern of the first layer 11. Further, (b) is a second layer 12 printed by overlapping the code pattern of the first layer 11 with a bit string based on numerical values, and the code pattern of the first layer 11. It is a quadratic figure by the equation converted from the numerical value of. In addition, the combination of code patterns is not limited to these examples.

22 and 23 show a configuration example for identifying the code pattern determined by FIGS. 19 and 20 when reading a card or the like. FIG. 22 corresponds to FIG. 19 and FIG. 23 corresponds to FIG. 20.

In Fig. 22, the conversion section 33 obtains an estimate of the second code pattern data based on the first code pattern data read from the card or the like. The processing in the conversion unit 33 is the same as that in the conversion unit 31 in FIG. Then, the second code pattern data read from the card or the like is compared with the estimated value by the comparison unit 34, and if a match is found, the card is recognized as a true card or the like. The comparison in the comparison unit 34 may be a comparison on the recognized image, in addition to the comparison of the code pattern data format. For example, it may be determined whether or not the recognition image of the second code pattern is equipped with the characteristic by the estimated value obtained from the conversion unit 33.

In FIG. 23, the pre-conversion unit 35 is provided before the conversion unit 33, and the pre-conversion unit 35 performs conversion by encryption or conversion table. Other operations are the same as those shown in FIG.

In the above, this invention was demonstrated by preferable embodiment of this invention. Although the present invention has been described with specific specific examples, it is apparent that various modifications and changes can be made to these specific examples without departing from the broad spirit and scope of the invention as defined in the claims. That is, the present invention should not be construed as being limited by the detailed description of the specific examples and the accompanying drawings.
