However, more clever and vicious fraudsters have occurred frequently, which has been a problem.
For example, when the structure is sealed so that a genuine case (hereinafter referred to as a genuine case) is not opened by the above-described caulking or the like, an attempt is made to tamper with the genuine control board that is accommodated. Then, the caulking part is destroyed and the genuine case is released, and in general, cheating is overlooked. However, according to clever fraudsters, forgery and preparation of a fraud case having the same shape as the genuine case (hereinafter referred to as fraud case) in advance, An extremely malicious means has been taken in which an unauthorized modification or the like is carried out and then accommodated in an unauthorized case and sealed by caulking or the like. In other words, since the fraud case and the genuine case have the same shape and size, if a control board that has been tampered with is contained in the fraud case, it cannot be distinguished from the genuine case, and there is evidence of fraud. It was extremely difficult to discover.

  The present invention has been made in view of the above-described problems of the prior art and problems required in the field of gaming machines, and an object thereof is to provide a gaming machine that finds evidence of fraudulent acts.

The first invention is a game machine 1 met with a control board unit UN formed and a substrate housing case for housing the control board A and the control board A, the number placed Alignment fine A holding layer 7 embedded with a part of the glass beads 5 exposed, a printed layer 4 printed on the exposed surface side of the multiple glass beads 5, and the holding layer 7 side. the reflective layer 6 that reflects irradiation light of a predetermined wavelength irradiated from the side of the exposed surface of the plurality of glass beads 5, which have a identification seal LB is a transparent bag shape and sealed into a sheet holder ST The printed layer constitutes identification information for identifying the control board unit UN, the control board A includes a CPU and a ROM, and at least one of the CPU or the ROM has management information, The identification information and the tube Information uniquely associates found that the identification seal LB sealed in the holder ST is an outer surface of the substrate accommodating case, characterized in that it is attached toward the print layer 4 on the outer .
A second aspect of the invention is a gaming machine 1 including a control board unit UN formed with a control board A and a board housing case for housing the control board A. A holding layer 7 embedded with a part of the glass beads 5 exposed; a printed layer 4 printed on the exposed surface side of the multiple glass beads 5; and the holding layer 7 side. A discriminating seal LB having a reflection layer 6 that reflects the irradiation light of a predetermined wavelength irradiated from the exposed surface side of the plurality of glass beads 5 is sealed in a transparent bag-like and sheet-like holder ST; The printed layer constitutes identification information for identifying the control board unit UN, the control board A includes a CPU and a ROM, and at least one of the CPU or the ROM has management information, and the identification Information and said tube Information uniquely associated and the substrate housing case is formed of a transparent material, the identification seal LB sealed in the holder, the printing layer 4 toward the outside of the substrate housing case, the substrate housing It is attached to the inside of the case.
The third invention is characterized in that a thin notch that is easy to break is formed on one surface of the holder.

  The control board unit that accommodates the control board to which the identification seal is attached has a proving ability for the authenticity of the control board unit (or the gaming machine). Thus, for example, if a control board unit with a genuine control board with an identification seal attached is tampered with and replaced with another control board unit with a control board without an identification seal attached, The trace of will remain.

  In addition, the identification seal has a holding layer embedded with a part of a large number of aligned fine glass beads exposed, a printed layer printed on the exposed side of the large number of glass beads, and a holding layer. Since it has a reflective layer that is provided on the side of the layer and reflects the irradiation light of a predetermined wavelength irradiated from the exposed surface side of a large number of glass beads, it is based on the structure of the identification seal and the wavelength of the irradiation light A unique optical pattern results. Furthermore, since it is attached outside the substrate housing case, it is possible to examine the optical pattern by irradiating the identification sticker with irradiation light of a predetermined wavelength from the printed layer side of the identification sticker. That is, if an illegal act such as peeling off the identification seal is performed, the printed layer is damaged and the structure of the original identification seal is deformed, so that the optical pattern unique to the identification seal cannot be maintained. Therefore, a trace of fraudulent activity remains on the identification seal, and it can be discovered that the fraudulent activity has been made.

  Furthermore, the printing layer of the identification sticker constitutes the identification information of the identification sticker, and at least one of the CPU and the ROM mounted on the control board has management information. Here, the form of the identification information is not particularly limited, and may be an identification number composed of a predetermined character string, a predetermined symbol, a figure, or the like. On the other hand, the possession mode of the management information to the CPU or the like is not particularly limited, for example, a method of directly stamping the management information on the surface of the package of the CPU or the like, a method of sticking a seal printed with the management information, a ROM There is a method for storing management information. The form of the management information itself is not particularly limited, and may be an identification number composed of a predetermined character string, a predetermined symbol, a figure, or the like. The identification information is uniquely associated with the management number of the CPU or ROM. Therefore, even if the CPU is replaced with a fraudulent CPU or the like, the fraud can be found from the relationship between the identification information of the identification sticker and the management number of the CPU or the like. From another point of view, it is possible to remove the identification seal from the genuine control board unit and prevent reuse of the identification seal that is diverted to an unauthorized control board unit.

  An identification seal is attached to the substrate housing case, and the identification seal is printed on the side of the holding layer embedded with a part of a large number of aligned fine glass beads exposed and the exposed surface of the large number of glass beads. And a reflective layer that is provided on the side of the holding layer and reflects irradiation light of a predetermined wavelength that is irradiated from the exposed surface side of many glass beads. The print layer constitutes identification information for identifying the control board unit UN, and the control board includes a CPU and a ROM, and at least one of the CPU and the ROM has management information. The identification information and the management information are uniquely associated. Therefore, it is possible to find evidence of fraud.

The CPU executes a program stored in the ROM, thereby performing control for a game operation or the like. A management number for identifying the CPU and ROM is directly engraved on the surface of the CPU package and the surface of the ROM package. These management numbers are uniquely associated with the identification numbers embodied by the print layer 4 of the identification seal LB described later.

  The first substrate case B has the above rectangular box shape by having a rectangular top plate portion 2a and side walls (reference numerals omitted) extending from the top plate portion 2a and hanging down. A plate portion 2b is formed so as to protrude outwardly from the shape base portion (reference numeral omitted) in a tongue-like shape. And the identification seal LB mentioned later is stuck on the plate | board surface of the board part 2b. Further, as shown in FIG. 5, a plurality (four in this embodiment) of screw holes 2c penetrating toward the second substrate case C side are formed in the vicinity of the plate portion 2b of the base portion described above. A first fitting protrusion 2d to be inserted into a fitting hole 3a formed in a predetermined portion of the second substrate case C is formed.

The rectangular bottom surface 3d of the second substrate case C has a large number of protrusions 3e for placing the main control substrate A and fitting holes 2i (formed at predetermined positions on the side wall of the first substrate case B). A second fitting protrusion 3f to be inserted into the first board case B is formed, and a plurality of (four in the present embodiment, 4) facing each of the screw holes 2c formed in the first substrate case B are formed. 3) of screw receiving portions 3g. Each screw receiving portion 3g is formed with a female screw groove communicating with each screw hole 2c.
Next, a method for manufacturing the control board unit UN will be described.

First, the main control board A is attached to the first board case B shown in FIG. Here, the external connection sockets Sa to Sg are inserted into the loose fitting holes ha to hg formed in the base portion 2e, and the region of the insulating substrate D on which the CPU, ROM, electronic components, etc. are mounted is defined. A locking hole (not shown) accommodated in the base portion of the first substrate case B and formed at a predetermined position of the insulating substrate D, and a locking protrusion (not shown) formed at a predetermined position of the first substrate case B The main control board A is attached to the lower surface of the first board case B by engaging with (not shown).
Next, with the main control board A attached to the lower surface of the first board case B, the first board case B is assembled so as to cover the second board case C.

  Here, the fitting protrusion 3f formed in the second substrate case C is fitted into the fitting hole 2i (see FIG. 3) formed in the first substrate case B, and the first substrate case B After fitting the fitting parts 2g and 2h formed on the rail part 3b and 3c formed on the second substrate case C, the fitting parts 2g and 2h are attached to the rail parts 3b and 3c. By sliding, the fitting protrusion 2d formed on the first substrate case B is fitted into the fitting hole 3a formed on the second substrate case C. As a result, as shown in FIGS. 3 and 4, the fitting projection 3f and the fitting hole 2i are fitted, the fitting projection 2d and the fitting hole 3a are fitted, and the first substrate case B is further fitted. When the fitting portions 2g and 2h formed on the rail and the rail portions 3b and 3c formed on the second substrate case C are fitted, the first and second substrate cases B and C are firmly combined. Further, the main control board A is sealed and accommodated in the first and second board cases B and C in a state where the insulating board D is placed on the protrusion 3e. That is, as shown in the cross-sectional view of the relevant part in FIG.

Next, when the first and second substrate cases B and C are combined as described above, as shown in the cross-sectional view of FIG. 7 (cross-sectional view broken along the screw hole 2c and the screw receiving portion 3g), The plurality of screw holes 2c formed in the one substrate case B and the plurality of screw receiving portions 3g formed in the second substrate case C communicate with each other, and are fixed in the individual screw holes 2c. The screws Na to Nd are inserted and screwed into the respective screw receiving portions 3g, so that the first and second substrate cases B and C are more firmly integrated and combined, and the heads of the fixing screws Na to Nd are further combined. By sealing the portion with a thermoplastic resin or the like, the fixing screws Na to Nd are prevented from coming off, and the first and second substrate cases B and C cannot be disassembled illegally.
And the control board unit UN is completed by sticking the identification seal | sticker LB on the board surface of the board part 2b.

  According to the structure and the manufacturing method of the control board unit UN explained above, the main control board A is accommodated in the first and second board cases B and C and fixed with the fixing screws Na to Nd only by the combination process. In addition, the process of sealing the heads of the fixing screws Na to Nd with a thermoplastic resin and the process of pasting the identification seal LB on the plate surface of the plate part 2b are realized by simple processes. can do. For this reason, it is possible to simplify, automate, rationalize the production line.

Next, the structure of the identification seal LB described above will be described.
FIG. 8A is a cross-sectional view showing a longitudinal cross-sectional structure of the identification seal LB. Note that the structure of the identification seal LB is simplified for easy understanding.

  In FIG. 8A, the identification seal LB includes a printed layer 4, a glass bead layer made up of a large number of fine glass beads 5 arranged in alignment, a reflective layer 6, a holding layer 7, and a base material 8. The base material 8 has a support layer 9 and an adhesive layer 10. In the following, the printed layer 4 is attached to the front side of the identification seal LB (the side to be irradiated with irradiation light described later), and the base material 8 is attached to the back surface of the insulating substrate D shown in FIGS. The back side.

  Further, in the manufacturing process for manufacturing the identification seal LB, a polyethylene resin or the like is applied to the upper surface of a film such as a PET film, and a number of fine glass beads 5 are sprayed and dried on the upper surface of the film, thereby the hemispherical surface of the glass beads 5. (The hemisphere on the side of the polyethylene resin or the like) is buried in the polyethylene resin, and then the reflective layer 6 is vapor-deposited on the exposed hemisphere of the glass beads 5, and the protective layer 7 formed on the substrate 8 is further applied to the reflective layer. 6, and a film such as a PET film is peeled off. Finally, a printed layer 4 is formed on the upper surface of a glass bead layer made up of a large number of fine glass beads 5, and cut into a predetermined size and shape. By doing so, the identification seal LB is formed.

  Each fine glass bead 5 is an extremely small spherical glass bead (in other words, a powdery glass bead) that cannot be visually recognized unless enlarged using a microscope or the like. They are arranged on the holding layer 7 in an orderly manner in a two-dimensional direction. Here, the hemispherical surface (substantially half spherical surface on the back surface side) of the glass beads 5 is embedded in the holding layer 7 via the reflective layer 6. The hemisphere on the upper surface side of the glass beads 5 (substantially half of the spherical surface on the upper surface side) is exposed or covered with the printing layer 4. That is, patterns such as letters, symbols, and patterns are printed as a printed layer 4 on a large number of glass beads 5 that are arranged in a two-dimensional direction, and the glass beads 5 that are not covered by the printed layer 4 are external. The glass beads 5 exposed to and covered with the printing layer 4 are not exposed to the outside.

Further, the glass beads 5 are irradiated light irradiated from the upper surface side of the identification seal LB (in this embodiment, visible light in which a plurality of wavelengths within a wavelength range of 390 to 770 nm are mixed, or visible light having a single wavelength. It is made of a fine spherical glass having a refractive index for refracting the irradiated light and emitting it to the upper surface side. For example, it is formed of fine spherical glass such as BaO—SiO ₂ glass or BaO—ZnO—TiO ₂ glass.

  The print layer 4 is an ink layer on which identification information for identifying the control board unit UN is printed. The identification information is uniquely associated with the management number (or identification number) assigned to the CPU or ROM of the main control board A described above. Therefore, even if the CPU is replaced with a fraudulent CPU or the like, the fraud can be found from the relationship between the identification information of the identification seal LB and the management number of the CPU or the like. From another viewpoint, it is possible to prevent the identification seal LB from being removed from the genuine control board unit UN and reuse of the identification seal LB diverted to an unauthorized control board unit.

  Moreover, the heat of the printing layer 4 is in the range of 0.5 to 5 μm. More specifically, when the printed layer 4 is lightly touched and rubbed with a human hand (mainly a finger or a nail), the printed layer 4 is peeled off from the glass beads 5, and the upper surface of the glass beads 5. Is formed to such a thickness that will be exposed. In this way, by forming the printed layer 4 that will be peeled off when touched and rubbed lightly by a human hand, it is possible to know the trace touched by the fraudster's hand. Unauthorized acts against the UN can be found and prevented.

  The printing layer 4 is formed of the above-described opaque ink that does not transmit the irradiation light or colored transparent ink that has a predetermined transmittance that transmits a part of the irradiation light. The printing layer 4 may be an ink of any of inorganic pigments and organic pigments, or may be ink obtained by mixing light scattering powder or the like in these pigments. The printing method may be any of letterpress printing, photolithographic printing, waterless flat printing, gravure printing, engraving letterpress printing, screen printing, collotype printing, or a method of printing by spraying ink with an inkjet printer or the like. good.

  The reflective layer 6 is made of a material such as a thin metal material that completely reflects the irradiation light irradiated on the glass beads 5 from the upper surface side of the identification seal LB, or a metal compound having a predetermined light transmittance that transmits a part of the irradiation light. It is formed with. When the reflective layer 6 is formed of a metal compound having a predetermined light transmittance that transmits a part of the irradiation light, a single thin layer (with a metal compound that emits a structural color by interfering with the irradiation light ( The layer has a thickness approximately equal to the wavelength of the irradiation light), and titanium oxide, bismuth oxide, zirconium oxide, silicon oxide, zinc oxide, or the like is used. Further, when the reflective layer 6 is formed of a metal compound having a predetermined light transmittance that transmits a part of the irradiation light, a metal compound having a high refractive index and a metal compound having a low refractive index with respect to the irradiation light It is also formed as a thin layer (a layer having a thickness similar to the wavelength of irradiation light) having a multilayer structure in which alternating layers are stacked, and as a metal compound having a high refractive index, titanium oxide, zinc oxide, tin oxide, indium oxide Zirconium oxide, silicon oxide, magnesium oxide and the like are used, and calcium fluoride, magnesium fluoride, sodium fluoride, silicon oxide and the like are used as the metal compound having a low refractive index.

  The holding layer 7 is a layer for holding the glass beads 5 on the substrate 8, for example, a polyethylene resin, a polyester resin, an acrylic resin, a silicone resin, a fluororesin, a polyamide resin, a polyvinyl alcohol resin. Further, it is made of a thermoplastic resin such as polyurethane resin, polyolefin resin, polycarbonate resin or polysulfone resin. The holding layer 7 is formed as a thin layer that can hold the glass beads 5 away from the substrate 8.

  The support layer 9 of the base material 8 is a layer that determines the mechanical strength of the control board unit UN and is formed of a film-like sheet such as a polyester resin, a polyolefin resin, a cellulose resin, or an acrylic resin. .

  The pressure-sensitive adhesive layer 10 is provided on the back side of the support layer 9, and a polyester-based pressure-sensitive adhesive, an acrylic adhesive, a urethane-based adhesive, or a vinyl oxide-based adhesive is used. Then, the back surface of the adhesive layer 10 is covered with a release paper (not shown), the release paper is peeled off, and the exposed adhesive layer 10 is attached to the plate surface of the plate portion 2b shown in FIGS. Thus, the identification seal LB is attached to the plate portion 2b.

  When the identification seal LB described above is pasted on the plate portion 2b, a so-called quality assurance function or the like indicating that the control board unit UN is genuine is exhibited and contributes to the discovery and prevention of fraud. Can do.

  In other words, when a game manager or the like manages or carries the light emitting device that emits the irradiation light of the predetermined wavelength described above, and checks the presence or absence of abnormality of the pachinko machine, it is affixed to the control board unit UN. Irradiation light is applied to the upper surface of the identification seal LB.

  When the irradiation light is irradiated in this way, the light incident on the glass beads 5 not covered with the printing layer 4 shown in FIG. 8A is refracted and returned to the outside on the surface side as return light. For this reason, the color of the reflective layer 6 is emphasized, and an optical pattern having a brighter color than the color seen under natural light (see FIG. 8B) is generated (see FIG. 8C). Further, since the refracted return light is shielded or absorbed by the printing layer 4 from the glass beads 5 covered with the printing layer 4, it does not return to the outside or is attenuated and returns. Since the glass beads 5 that are not covered with the layer 4 return to the outside with almost no dimming or the like, a contrast is generated between the region where the print layer 4 is present and the region where the print layer 4 is not present. (See FIG. 8C).

  Further, when the reflective layer 6 is a single thin layer formed of a metal compound or the like having a predetermined light transmittance that transmits a part of the irradiated light, a structural color is generated by the interference action of light. Then, an optical pattern having a color that is colored with the structural color is generated. Further, when the reflective layer 6 is a thin layer having a multilayer structure formed of a metal compound or the like having a predetermined light transmittance that transmits a part of the irradiation light, it is refracted with a metal compound or the like having a high refractive index. A structural color is generated by the interference action of light caused by a metal compound or the like having a low rate, and an optical pattern having a color that is colored with the structural color is generated. Further, when the reflective layer 6 is formed of a metal material that totally reflects the irradiated light, an optical pattern having a color that is colored with the reflected light is generated.

  In addition, when the reflective layer 6 is adjusted to a predetermined light transmittance, an optical pattern is not generated with natural light, and an optical pattern can be generated only when irradiation light with a predetermined wavelength is irradiated.

  Since the optical pattern is a pattern having a specific color determined by the above-described refraction of light by the glass beads 5 and the interference of light by the reflective layer 6, the optical pattern is formed between the identification seal LB and the irradiation light. It is possible to determine whether or not the control board unit UN is genuine by visually checking whether or not the pattern is a unique pattern.

  As described above, when irradiation light (visible light) having a predetermined wavelength is applied to the identification sticker LB, an optical pattern peculiar to the identification sticker LB is generated. When a peculiar optical pattern is generated, the control board unit UN On the other hand, if a pattern different from the specific optical pattern is generated or if no optical pattern is generated, it is determined that the control board unit UN is a counterfeited illegal one. , Can discover cheating.

  Further, the material, size, arrangement, etc. of the glass beads 5 are adjusted, the thickness, material, transmittance, etc. of the reflective layer 6 are adjusted, or the reflective layer 6 is made into a single layer or a multilayered layer. When adjusted, the optical pattern with respect to the wavelength of the irradiation light (visible light) can be changed, and those adjustments can be made only by a precise manufacturing process. For this reason, it is almost impossible to forge the identification seal LB, and forgery can be prevented. Furthermore, since a genuine identification seal LB that cannot prevent counterfeiting and generates a unique optical pattern is attached to the control board unit UN, it is possible to reliably find a control board unit that has been tampered with. As a result, it is possible to prevent fraud.

  In addition, the identification seal LB has a simple structure that can be manufactured at a low cost compared to electronic components such as an IC tag. It has a structure that exhibits a special function that can surely prevent the above.

  As described above, in the pachinko machine 1 of the present embodiment, the identification seal LB having a structure that generates a specific optical pattern when irradiated with irradiation light of a predetermined wavelength is novel. Since the control board unit UN is provided as a fraud prevention means, it is possible to prevent a high cost and to reliably prevent fraud.

  The identification seal LB of the first embodiment described above is formed in a rectangular shape such as a rectangle or a square as shown in FIGS. 3 and 4, but has a circular shape such as a circle or an ellipse. It may be formed. When the identification seal LB is pasted on the control board unit in the manufacturing process, the process of peeling and pasting the identification seal LB from the release paper is facilitated, which is preferable for mechanization of the production line. .

  Further, in the first embodiment, the substrate housing case is opened by sliding the substrate cases B and C slidably fitted by the fitting portions 2g and 2h and the rail portions 3b and 3c. The (opened) structure is not limited to this. For example, the substrate housing case may be composed of a lid-shaped first substrate case B and a rectangular box-shaped second substrate case C, and the substrate cases B and C may be pivotally connected by a hinge. In this case, the fitting protrusions 2d and 3f and the fitting holes 3a and 2i are provided at positions where the board cases B and C are properly fitted when the board cases B and C rotate around the hinge axis and the board housing case is sealed. It only has to be done.

Furthermore, in the first embodiment, the main control board A is attached to the first board case B. However, the main control board A may be attached to the second board case C.

  In the first embodiment, the fitting protrusions and fitting holes are formed in the substrate cases B and C, but the fitting structure of the substrate cases B and C is not limited to this. For example, even in a pattern in which only one fitting protrusion is formed in the substrate case B and only one fitting hole is formed in the substrate case C, only one fitting hole is formed in the substrate case B. The substrate case C may have a pattern in which only one fitting protrusion is formed. Further, the second substrate case C is divided into two, a fitting hole is formed in each component of the second substrate case C, and two fitting protrusions are formed in the first substrate case B. A structure in which the constituent members of the second substrate case C are inserted from the outside of both end portions of the first substrate case B may be employed.

  In Embodiment 1, the identification seal LB is affixed to the plate-like portion 2b formed outside the first substrate case B, but the location where the identification seal LB is affixed is not limited. For example, the other part (base | substrate part, a base part, etc.) of the 1st substrate case B, the inside of the 1st substrate case B, or the 2nd substrate case C may be sufficient.

  In the first embodiment, the management number is directly stamped on the surface of the package of the CPU and the ROM, but the management number is placed on the surface of the package of the CPU. A method of sticking the attached sticker or a method of storing the management number in a storage device provided in a ROM or the like may be used.

This embodiment relates to an identification seal LB having a different structure from the identification seal LB having the structure shown in FIG. Since the control board unit UN is the same as that of the first embodiment, the description thereof is omitted.

  In the identification seal LB of the present embodiment shown in FIG. 9, a protective layer 11 made of printing ink or thermoplastic resin is formed on the peripheral edge of the identification seal LB. Here, the protective layer 11 is formed on the upper surface of the printing layer 4 like a ridge having a height of about 5 μm. The structures and materials of the printing layer 4, the glass beads 5, the reflection layer 6, the holding layer 7, and the substrate 8 are the same as those in the first embodiment.

  Next, the identification seal LB shown in FIG. 10 has a protective layer 11 made of printing ink or thermoplastic resin at the peripheral edge of the identification seal LB. Here, the protective layer 11 is formed on the upper surface of the glass bead 5 like a ridge having a height of about 5 μm. The structures and materials of the printing layer 4, the glass beads 5, the reflection layer 6, the holding layer 7, and the substrate 8 are the same as those in the first embodiment.

  According to the identification seal LB shown in FIG. 9 and FIG. 10, it is possible to detect and prevent fraud by generating the unique optical pattern described in the first embodiment. In addition, the presence of the protective layer 11 allows printing. Generation | occurrence | production of the problem of touching the upper surface of the layer 4 carelessly can be reduced.

  The identification seal LB shown in FIGS. 9 and 10 corresponds to a modification of the identification seal LB shown in FIG. 7, but the protective layer 11 is provided on the peripheral edge of the identification seal LB shown in FIG. It may be formed. And, when the protective layer 11 is formed on the peripheral edge of the identification seal LB shown in FIG. 8, it is possible to detect and prevent fraud by generating the unique optical pattern described in the second embodiment. Occurrence of a problem that the upper surface of the print layer 4 is inadvertently touched can be reduced.

(Embodiment 4)
Next, Embodiment 4 will be described with reference to FIG.
The present embodiment relates to a modification of the identification seal LB described in the first to fourth embodiments. That is, as shown in the perspective view of FIG. 11A and the cross-sectional view taken along the line XX of FIG. 11B, this embodiment uses any one of the identification seals LB shown in FIGS. It is housed and sealed in a thin bag-like and sheet-like holder ST having two sheet surfaces formed of a so-called hard transparent plastic material such as transparent acrylic resin or polycarbonate resin, and the whole has a new structure. The identification seal LBA is used. And the identification seal | sticker LBA is attached to predetermined parts, such as 1st, 2nd board | substrate cases B and C demonstrated in Embodiment 1-4.

  According to the present embodiment, the identification seal LB that generates a unique optical pattern when irradiated with irradiation light of a predetermined wavelength is hermetically housed in the holder ST. Even if a pachinko machine is installed in the field, the problem that dust, cigarette smoke, and the like adhere to the identification seal LB and become contaminated can be reduced, and deterioration of the identification seal LB can be prevented.

  In this embodiment, the identification seal LB is sealed and accommodated in the holder ST. However, a transparent acrylic resin or polycarbonate is provided on the upper surface of the identification seal LB (the surface on which irradiation light is irradiated). A thin plate-like sheet formed of a so-called hard transparent plastic material such as a resin may be attached so as to be opposed to cover the upper surface of the identification seal LB. That is, the identification seal LB may not be accommodated in the holder ST, but the upper surface of the identification seal LB may be covered with the sheet.

However, when affixing the sheet so as to cover the upper surface of the identification seal LB with the sheet, the peripheral part of the identification seal LB and the peripheral part of the sheet are adhered with an adhesive or the like, and the inside of the peripheral part of the identification seal LB (irradiation) It is desirable that the region irradiated with light and the sheet face each other through a gap. If the inner side of the peripheral portion of the identification seal LB (region irradiated with irradiation light) is bonded to the sheet, the optical pattern generated by irradiation of the irradiation light may be deformed, and the original optical pattern cannot be obtained. is there.
Further, the above-described holder ST and the sheet need not be a colorless and transparent plastic material, but may be formed of a colored and transparent plastic material that transmits irradiation light.

Moreover, it is also possible to print characters, designs, etc. with colored transparent ink on the above-described holder ST or part of the sheet. For example, quality display and identification display can be performed by printing a trademark, a company name, a logo mark, and the like with colored transparent ink.
(Embodiment 5)
Next, Embodiment 5 will be described with reference to FIG. The present embodiment relates to a modified example of the identification seal LBA described in the fourth embodiment.

  That is, as shown in the perspective view of FIG. 12A, the present embodiment is a thin bag-like and sheet-like holder ST formed of a so-called hard transparent plastic material such as a transparent acrylic resin or polycarbonate resin. In addition, the identification seal LB described in the first to fourth embodiments is accommodated.

  Here, on one sheet surface of the holder ST, an extremely thin and thin cut K is formed that is broken only by contact with a weak force, and the sheet surface on which the cut K is formed is shown in FIGS. The base material 8 of the identification seal LB shown in 10 or the like is brought into close contact, and the identification seal LB is accommodated in the holder ST. That is, FIG. 12A is a perspective view when viewed from the base material 8 side of the identification seal LB.

  Further, the adhesion between the base material 8 of the identification seal LB and the sheet surface on which the cut K is formed is performed at the peripheral portion of the base material 8 and is performed in the region where the cut K on the sheet surface is formed. Not.

  And the identification seal | sticker LBA shown to Fig.12 (a) is used for predetermined parts, such as 1st, 2nd board | substrate cases B and C demonstrated in Embodiment 1-4 by making the sheet | seat surface in which the cut K is formed into an adhesive surface. It is attached. That is, it is attached to predetermined portions such as the first and second substrate cases B and C so that the irradiation surface can be irradiated with the irradiation light. Further, the peripheral portion of the sheet surface on which the cut K is formed and the predetermined portions such as the first and second substrate cases B and C are bonded with an adhesive, and in the region where the cut K on the sheet surface is formed. Bonding is not performed.

  According to the present embodiment, the surface on the side irradiated with the irradiation light of the identification seal LB accommodated in the holder ST is covered with one sheet surface of the holder ST (the sheet surface not provided with the cut K). Therefore, even if a pachinko machine is installed in a game room where there is a lot of dust or cigarette smoke, the problem of dust or cigarette smoke adhering to and contaminating the identification seal LB can be reduced. Deterioration of LB can be prevented.

  Furthermore, when an unauthorized person tries to peel off the identification seal LBA attached to a predetermined portion such as the first and second substrate cases B and C, the notch K of the holder ST is formed. The sheet surface is broken along the notch K, and the internal identification seal LBA is also damaged. For this reason, traces of fraudulent acts remain on the identification seal LB, and the fraudulent acts can be found by irradiating the irradiation light and viewing the deformed optical pattern under the influence of the traces.

  Further, even when an unauthorized person peels off the identification seal LBA and attaches it to a counterfeit control board unit for reuse, the trace of damage attached to the identification seal LB remains during the peeling action. When light is irradiated, it is possible to see an optical pattern that is deformed under the influence of the traces, and it is possible to discover fraud.

  The identification seal LBA of the sixth embodiment described above is bonded with the base material 8 (see FIGS. 7 to 10) of the identification seal LB and the sheet surface on which the cut K is formed facing each other, The identification seal LB is accommodated in the holder ST. On the contrary, the surface of the identification seal LB on which the irradiation light is irradiated and the sheet surface on which the cut K is formed are opposed to each other. Then, the peripheral portions of these surfaces may be bonded to each other so that the identification seal LB is accommodated in the holder ST. That is, it is good also as a structure which irradiates irradiation light to the sheet | seat surface side in which the cut K is formed.

  Thus, when the structure of the identification seal LBA is a structure in which the irradiation light is irradiated on the sheet surface side where the cut K is formed, the cut K is reflected in the optical pattern generated by the irradiation of the irradiation light. There is nothing to spoil the original features of the optical pattern. For this reason, it is possible to determine the presence or absence of fraud by looking at the optical pattern.

  Furthermore, when an unauthorized person tries to peel off the identification seal LBA, or when it is attached to a control board unit that has been forged off and reused, the notch K breaks during the peeling action, and the identification seal LB Traces of damage remain on the printed layer 4 (see FIGS. 7 to 10). For this reason, when irradiated with irradiation light, an optical pattern deformed under the influence of the trace can be seen, and an illegal act can be found. Further, even on the sheet surface where the notch K of the holder ST is formed, the identification seal LB is covered from the outside unless the notch K is broken, so that the pachinko is placed in the game hall where there is a lot of dust or cigarette smoke. Even if the machine is installed, it is possible to alleviate the problem that dust, cigarette smoke, and the like adhere to the identification seal LB and become contaminated, and the deterioration of the identification seal LB can be prevented.

  As another modification, the holder ST may be formed of a colored transparent plastic material as described in the fourth embodiment. In addition, a trademark, a company name, a logo mark, or the like may be printed on the holder ST with colored transparent ink. Further, as shown in FIG. 12B, a bar code BC having identification information or the like may be attached to one end of the holder ST, which can further prevent fraud.

  Further, as described in the fourth embodiment, instead of the holder ST shown in FIG. 12A, a thin sheet formed of a hard transparent plastic material and having a cut K formed thereon is irradiated with the irradiation light of the identification seal LBA. However, the sheet on which the cut K is formed may be attached to the back surface of the identification seal LB. As described above, even if the sheet is attached to the back surface of the identification seal LB, the incision K is broken when the fraud is performed, and the identification seal LB is left with a trace due to damage or the like, which contributes to prevention of the fraud. Is possible.
