Description

  The present invention relates to a gaming machine provided with fraud prevention means for detecting and preventing fraud.

  Game machines such as pachinko machines and slot machines control game operations and effects by various control boards such as a main control board on which electronic components such as a CPU and a ROM are mounted and an effect control board.

  Conventionally, in order to prevent fraud, a gaming machine in which a board on which electronic components are mounted is housed in a board case assembled with a plurality of parts and the board case is irreversibly caulked is known. (For example, see Patent Documents 1 and 2). However, fraud is also applied to such gaming machines.

  For example, there is a case where fraud is performed by destroying the substrate case. In such a case, it is possible to find out that fraud has been performed by a trace of the destruction of the substrate case. However, as a fraudulent act, when a board with fraud is stored in a board case with the same shape as the genuine board case and the whole board case is replaced, the board case has no evidence of destruction. I cannot discover what is being done.

  Therefore, an identification seal for identifying the authenticity is attached to an appropriate location such as a substrate case or a substrate. In addition, a seal is attached to the opening / closing part of the substrate case to indicate that the substrate case has been sealed, and to mark the opening or disassembly.

  In this way, fraud prevention such as identification seals and seal seals to prevent fraud is affixed to prevent fraud, but the fraud prevention seal adhesive is dissolved (the adhesive action of the adhesive is reduced). The anti-tamper seal may be easily peeled off by the solvent (which expires).

  In view of the above background, an object of the present invention is to provide a gaming machine that suppresses fraud.

In order to achieve such an object, a first invention is a gaming machine to which a fraud prevention seal for preventing fraud is attached, wherein the fraud prevention seal is bonded to a component constituting the gaming machine. 1 base material, the 1st adhesive agent which interposes between the said component and the said 1st base material, and adhere | attaches the said component and the said 1st base material, and the 2nd group adhere | attached on the said 1st base material And a second pressure-sensitive adhesive that is interposed between the first base material and the second base material and adheres the first base material and the second base material to each other. The material includes a chemical that changes color in response to a solvent that deactivates the adhesive action of the first pressure-sensitive adhesive or the second pressure-sensitive adhesive.
In order to achieve this object, the second invention is characterized in that the first base material is exposed.

  The first base material contains a chemical that dissolves the first pressure-sensitive adhesive or the second pressure-sensitive adhesive and changes color in response to a solvent that invalidates the adhesive action of the first pressure-sensitive adhesive or the second pressure-sensitive adhesive. Therefore, when the anti-tampering seal is removed from the gaming machine and the solvent is applied to the anti-tampering seal, the first base material is discolored and a trace of the fraudulent act remains, so that the fraudulent act can be found. Moreover, when the first base material changes color, it becomes difficult to reuse fraud prevention, and fraud can be suppressed.

  Further, when the first base material is exposed, this solvent is applied to the first base material, and traces of fraudulent acts are likely to remain, and fraudulent acts are easily found and fraudulent acts are easily suppressed.

  The tamper-proof seal affixed to the gaming machine is interposed between the first base material bonded to the component constituting the gaming machine, the component and the first base material, and the component and the first base material A first pressure-sensitive adhesive that bonds the first base material, a second base material that is bonded to the first base material, and a first base material and a second base material that are interposed between the first base material and the second base material, And a second pressure-sensitive adhesive for adhering. And since the 1st base material contains the chemical | medical agent which changes color in response to the solvent which expires the adhesive effect by a 1st adhesive or a 2nd adhesive, an illegal act can be suppressed.

(Axial direction). That is, the first fitting protrusion 11 and the first fitting hole 21, and the second fitting protrusion 22 and the second fitting hole 12 face each other in the fitting direction. All axial directions are the same.

  Next, a method for manufacturing the main control board unit UN1 will be described. First, as shown in FIG. 5, the main control board A is attached to the first board case 10 from the lower side (the open side of the housing portion 10 </ b> A). Here, the external connection sockets Sa to Sg are inserted into the loose fitting holes 18a to 18g formed in the base portion 10B, and electronic components such as CPU, ROM, and electronic components are accommodated in the accommodating portion 10A, and insulated. By locking a locking hole (not shown) formed at a predetermined position of the conductive substrate D and a locking projection (not shown) formed at a predetermined position of the first substrate case 10, The main control board A is attached to the first board case 10.

  Next, the first substrate case 10 to which the main control substrate A is attached is combined so as to cover the second substrate case 20. Here, the fitting grooves 14 and 15 of the fitting portions 10C and 10D formed in the first substrate case 10 and the rail portions 24 and 25 formed in the second substrate case 20 are partially fitted. . As shown in FIG. 6, the second board is inserted into the second fitting hole 12 formed in the first board case 10 while sliding the fitting parts 10 </ b> C and 10 </ b> D with respect to the rail parts 24 and 25. The second fitting protrusion 22 formed on the case 20 is fitted, and the first fitting protrusion 11 formed on the first substrate case 10 is inserted into the first substrate case 20. Is fitted into the fitting hole 21.

  As described above, the first fitting protrusion 11 and the first fitting hole 21 are fitted, the second fitting protrusion 22 and the second fitting hole 12 are fitted, and the first substrate. By fitting the fitting portions 10C and 10D formed on the case 10 with the rail portions 24 and 25 formed on the second substrate case 20, the first substrate case 10 and the second substrate case 20 are rails. The relative movements of the portions 24 and 25 other than the length direction are combined firmly in a restricted state. At this time, the main control board A is placed on the base 26 in the sealed board case X.

Further, as described above, the first substrate case 10 and the second substrate case 20 are combined, and the first fitting projection 11, the first fitting hole 21, the second fitting projection 22, and the second fitting projection 22 are combined. When the fitting holes 12 are respectively fitted, as shown in FIG. 8, female screw grooves formed in the plurality of first screw receiving portions 17 (17 a to 17 d) of the first substrate case 10, The female screw grooves formed in the plurality of second screw receiving portions 27 (27a to 27d) of the second substrate case 20 are connected. Therefore, the first substrate case 10 and the second substrate case 20 are more firmly integrated by screwing the fixing screws Na to Nd into the female screw grooves formed in the screw receiving portions 17 and 27. Can do. In addition, by fixing the heads of the fixing screws Na to Nd with a thermoplastic resin or the like, the fixing screw Na
-Nd is prevented from coming off further, and the first substrate case 10 and the second substrate case 20 are irreversibly caulked.

  Then, as shown in FIG. 9A, a seal seal S1, which will be described later, is pasted from the bottom surface 200B of the second substrate case 20 to the outer side surface 104A of the side wall 104 of the first substrate case 10, and shown in FIG. 9B. As described above, a protective seal S2 to be described later is attached to the substrate case X from the top surface of the seal seal S1 to the outer surface 104A of the side wall 104 of the first substrate case 10 from the bottom surface 200B of the second substrate case 20. In this way, the first substrate case 10 and the second substrate case 20 are fitted, and the tamper-proof seal S is pasted on the abutting portions to manufacture the main control board unit UN1.

  Next, the structure of the above-described fraud prevention seal S will be described. FIG. 10A is a cross-sectional view illustrating a cross-sectional structure of the tamper-proof seal S attached to the gaming machine 1. The fraud prevention seal S includes a seal seal S1 bonded to the components constituting the gaming machine 1 and a protective seal S2 bonded to the seal seal S1. In the present embodiment, the parts constituting the gaming machine 1 are the first board case 10 and the second board case 20 constituting the main control board case X, and the sealing seal S1 and the protective seal S2 are the first board case 10. Is attached from the outer surface 104A of the side wall 104 to the other bottom surface 200B of the bottom plate 200 of the second substrate case 20. Specifically, the seal seal S1 is applied across the first substrate case 10 and the second substrate case 20, the protective seal S2 covers the entire first printed layer 33 of the seal seal S1, and further the seal seal S1. Affixed to the seal seal S1, the outer surface 104A, and the bottom surface 200B in a state of protruding outward from a part of the outer periphery.

  The seal seal S <b> 1 is formed on the first base material 31, the first adhesive 32 applied to one surface (back surface) of the first base material 31, and the other surface (front surface) of the first base material 31. The first print layer 33 is provided. The first base material 31 is bonded to the outer surface 104 </ b> A of the side wall 104 of the first substrate case 10 and the bottom surface 200 </ b> B of the bottom plate 200 of the second substrate case 20 by the first adhesive 32.

  The first base material 31 is made of Japanese paper such as a paper with a weak cohesive force (easy to break the material), and includes a petroleum solvent that dissolves the first adhesive 32 or the second adhesive 42 described later, and the petroleum solvent and a later description. It contains chemicals that change color in response to a mixture with the second adhesive. Moreover, this chemical | medical agent has the characteristic easy to melt | dissolve in the liquid mixture of a petroleum-type solvent and a 2nd adhesive.

  The first pressure-sensitive adhesive 32 is made of a rubber-based pressure-sensitive adhesive, a polyester-based pressure-sensitive adhesive, an acrylic pressure-sensitive adhesive, or a urethane-based pressure-sensitive adhesive. Before the seal seal S1 is attached to the adherend, the back surface of the first adhesive 32 is covered with a release paper (not shown), but the release paper is peeled off to expose the first adhesive 32. Thus, the seal seal S1 can be attached to the first substrate case 10 and the second substrate case 20.

  The first printing layer 33 is formed of an opaque ink that does not transmit the irradiation light, a colored transparent ink that has a predetermined transmittance that transmits a part of the irradiation light, or a colorless and transparent ink that transmits almost all of the irradiation light. Is done. The ink constituting the first printing layer 33 may be any ink such as pigment ink, dye ink, printing ink, or metal ink. Moreover, the ink which mixed the light scattering powder etc. in the inorganic pigment or the organic pigment may be used. In addition, as a printing method, according to the raw material of ink, letterpress printing, photoplate printing, waterless flat plate printing, gravure printing, engraving letterpress printing, screen printing, collotype printing, and a method of printing by spraying ink with an ink jet printer Alternatively, a method of transferring ink by a laser printer or the like is appropriately selected. Conversely, the ink raw material can be appropriately selected according to the printing method. The first print layer 33 represents first identification information d1 including predetermined characters, figures, patterns, or the like. Although the content of the first identification information d1 is not particularly limited, in the present embodiment, as the first identification information d1, a management number (for FIG. 10B) set for each model (type of gaming machine) “No. 210609”) and a frame surrounding the management number are displayed on the surface of the first base material 31. Further, as shown in FIG. 10B, in addition to the first identification information d1, a character (message) associated with the function of the seal seal S1 of “open prohibition” is formed on the first base material 31. The first printed layer 33 thus formed is similarly formed.

  The protective seal S <b> 2 is formed on the second base material 41, the second adhesive 42 applied to one surface (back surface) of the second base material 41, and the second surface (front surface) of the second base material 41. 2 printing layers 43. The second base material 41 is bonded to the first base material 31 and the first print layer 33 by the second adhesive 42. That is, the seal seal S1 and the protective seal S2 are laminated. The second base material 41 also has a laminated structure, and a support layer 44, a holding layer 45, a reflective layer 46, and a glass bead layer 47 are laminated from the second adhesive 42 side. The glass bead layer 47 is composed of a large number of fine glass beads 47A arranged in alignment.

  The protective seal S2 also has the same rectangular shape as the seal seal S1, but is generally larger than the seal seal S1. That is, the seal seal S1 and the protective seal S2 have a similar relationship, and the similarity ratio of the protective seal S2 to the seal seal S1 is greater than “1”. As shown in FIG. 10B, the protective seal S2 is attached to the seal seal S1, the outer surface 104A of the first substrate case 10 and the bottom surface 200B of the second substrate case 20 while covering the entire seal seal S1. It is attached. Therefore, in order to peel off the tamper-proof seal S from the substrate case X, at least a portion of the protective seal S2 protruding from the seal seal S1 is peeled off from the substrate case X, and then the seal seal S1 and the protective seal S2 are overlapped. The part must be peeled off from the substrate case X. In this way, illegal acts can be suppressed by providing multiple anti-fraud means.

  Further, since the seal seal S1 and the protective seal S2 are laminated, the authenticity relationship between the seal seal S1 and the protective seal S2 is preset in the fraud prevention seal S. Action can be suppressed. This is because when the positional relationship between the seal seal S1 and the protective seal S2 changes when the anti-tamper seal S is removed from the substrate case X, the anti-tamper seal S is reused to restore the main control board unit UN1. This is because if the positional relationship between the seal seal S1 and the protective seal S2 is not made the same as the original (before separation), a trace of fraudulent activity remains. For example, when a fraudster opens the substrate case X, a petroleum solvent that invalidates the adhesive action of the first adhesive 32 and the second adhesive 42 is applied to the fraud prevention seal S, and the fraud prevention seal S is applied to the substrate. Suppose that it was able to peel and remove from case X. However, when the tamper-proof seal S is peeled from the substrate case X, only the protective seal S2 located on the front side moves, and the positional relationship between the seal seal S1 and the protective seal S2 changes. If the positional relationship with the protective seal S2 is not made authentic, there will be a trace of fraud. Moreover, in the present embodiment, the sealing seal S1 attached to the substrate case X is completely covered with the protective seal S2, and the protective seal S2 is attached to the substrate case X in a state where it completely protrudes from the sealing seal S1. Therefore, it is not easy to remove the tamper-proof seal S from the substrate case X while maintaining the genuine positional relationship between the seal seal S1 and the protective seal S2. In this way, the fraud prevention seal S is provided with a means for inhibiting restoration, so that fraud is suppressed.

  Further, the protective seal S2 as a whole has a transparency that allows the other surface side to be seen through from one surface side. Here, since the protective seal S2 covers the portion of the seal seal S1 to which the first identification information d1 is attached, the first identification information d1 can be visually recognized by the protective seal S2. It is possible to prevent the deterioration of the part to which the information d1 is attached. The degree of transparency of the protective seal S2 is not particularly limited as long as the seal seal S1 is visible through the protective seal S2.

  Next, a method for manufacturing the protective seal S2 will be described. First, a polyethylene resin or the like is applied to the top surface of a film such as a PET film, and a number of fine glass beads 47A are sprayed thereon and dried to form a hemispherical surface of the glass beads 47A (a hemispherical surface on the polyethylene resin side). Are buried in polyethylene resin. Thereafter, the reflective layer 46 is vapor-deposited on the exposed hemispherical surface of the glass beads 47 </ b> A, the holding layer 45 is formed on the support layer 44, and the holding layer 45 is bonded to the reflective layer 46. Then, a film such as a PET film is peeled off, and finally the second printed layer 43 is formed on the upper surface of the glass bead layer 47 composed of a large number of fine glass beads 47A, and is cut into a predetermined size and shape.

  Each fine glass bead 47A is formed into an extremely small spherical shape (in other words, a powder form) that cannot be visually recognized unless enlarged using a microscope or the like. The holding layer 45 is laid in the direction (plane shape).

The glass beads 47A are light having a predetermined wavelength irradiated from the surface side of the protective seal S2 (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 that refracts the irradiated light and emits it to the surface side. For example, the glass is made of BaO—SiO ₂ glass, BaO—ZnO—TiO ₂ glass, or the like.

  A hemispherical surface (substantially half spherical surface on the back surface side) of the glass bead 47 </ b> A is embedded in the holding layer 45 through the reflective layer 46. The hemispherical surface (substantially half spherical surface on the surface side) of the glass bead 47 </ b> A is exposed or covered with the second printed layer 43. That is, the second print layer 43 is partially printed by printing patterns such as characters, symbols, and patterns constituting the second identification information d2 on a large number of glass beads 47A arranged in a two-dimensional direction. Is formed. The glass beads 47A not covered with the second printed layer 43 are exposed to the outside, and the glass beads 47A covered with the second printed layer 43 are not exposed to the outside.

  The second print layer 43 represents second identification information d2 made up of predetermined characters, figures or patterns. The content of the second identification information d2 is not particularly limited, but in the present embodiment, a model (product name) code (“KM” in FIG. 10C) is printed as the second identification information d2. ing. Thus, the first identification information d1 is displayed on the seal seal S1 by the first print layer 33, and the second identification different from the first identification information d1 is displayed on the protective seal S2 by the second print layer 43. Information d2 is displayed, and a combination of two pieces of identification information is associated with the fraud prevention seal S. Thereby, since it becomes difficult to reuse the fraud prevention seal S, fraud can be suppressed. The reason for this will be described below. For example, a seal seal from a fraud prevention seal (for example, model code “TK”, management number “260609”) of a certain model without leaving a trace by a petroleum-based solvent or the like that invalidates the adhesive action of the adhesives 32 and 42. It is assumed that only S1 is extracted, and only the protective seal S2 is extracted without leaving any trace from a fraud prevention seal (for example, model name “KM”, management number “000001”) relating to another model. In this case, even if the anti-fraud seal is forged by combining the seal seal S1 and the protective seal S2 with no trace of extraction, the same combination of identification information (model code “ KM ”and management number“ 260609 ”) may exist. As described above, since the combination of a plurality of identification information is associated with one fraud prevention seal, it becomes difficult to reuse and forge the fraud prevention seal, and therefore fraud can be suppressed. In the present embodiment, a frame surrounding the management number constituting the first identification information d1 is also formed on the first substrate 31 as the first print layer 33. As shown in FIG. 10C, the first print layer 33 according to this frame surrounds a part of the second print layer 43 according to the second identification information d2 without excess or deficiency. That is, the authenticity between the seal seal S1 and the protective seal S2 is obtained by the first print layer 33 related to the first identification information d1 of the seal seal S1 and the second print layer 43 related to the second identification information d2 of the protective seal S2. The positional relationship is configured.

  The second printing layer 43 includes the above-described opaque ink that does not transmit the irradiation light, a colored transparent ink that has a predetermined transmittance that transmits a part of the irradiation light, or a colorless and transparent ink that transmits almost all of the irradiation light. Formed with. The second print layer 43 may be an ink of any of inorganic pigments and organic pigments, and may be ink obtained by mixing light scattering powder or the like into these pigments. In the present embodiment, the second printed layer 43 is transparent to light of a normal wavelength and transmits almost all of the light in order to leave an improper trace. It is made of ink made of a material that reflects almost all of it. The printing method may be any of letterpress printing, photographic printing, waterless flat printing, gravure printing, engraving letterpress printing, screen printing, collotype printing, or a method of printing by spraying ink with an ink jet printer. However, a method of transferring ink using a laser printer may be used.

  The thickness of the second print layer 43 is in the range of 0.5 to 5 μm. Specifically, when the second printed layer 43 is lightly touched and rubbed with a human hand (mainly fingers or nails), the second printed layer 43 is peeled off from the glass beads 47A, and the surface of the glass beads 47A is exposed. It is formed with a thickness. As described above, the second printed layer 43 is formed which can be peeled off by lightly touching with a human hand. Thus, the trace of the fraudulent person's hand is known, and an illegal act against the main control board unit UN1 is found. As well as deterring fraud. In the present embodiment, a frame along the entire peripheral edge of the second base material 41 is formed as the second print layer 43 in addition to the second identification information d2. When the tamper-proof seal S is peeled off, the peripheral edge of the seal is held with a predetermined tool such as a finger or tweezers, and when the tamper-proof seal S is to be peeled off, the finger or the tool or the like is applied to the frame. A part of the second printed layer 43 is peeled off, leaving a trace in contact with the second printed layer 43. In addition, if the second printing layer 43 is colorless at the normal wavelength, it is difficult for an unauthorized person to notice the second printing layer 43, and therefore, the second printing layer 43 contacts the second printing layer 43 when removing the fraud prevention seal S. The traces that have been made are likely to remain.

  The reflective layer 46 is made of a material such as a thin metal material that completely reflects the irradiation light irradiated on the glass beads 47A from the surface side of the protective seal S2, 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 46 is formed of a metal compound having a predetermined light transmittance that transmits a part of the irradiation light, for example, as the reflection layer 46, a single metal compound that emits a structural color by causing the irradiation light of a predetermined wavelength to interfere with each other is used. One thin layer (a layer having the same thickness as the wavelength of irradiation light) is formed. As the metal compound, titanium oxide, bismuth oxide, zirconium oxide, silicon oxide, zinc oxide or the like is used. Further, even when the reflective layer 46 is formed of a metal compound having a predetermined light transmittance that transmits a part of the irradiation light, the reflection layer 46 is a metal compound having a high refractive index with respect to the irradiation light and a low refractive index. A thin layer having a multilayer structure in which metal compounds are alternately stacked (a layer having a thickness approximately equal to the wavelength of irradiation light) is formed. In this case, titanium oxide, zinc oxide, tin oxide, indium oxide, zirconium oxide, silicon oxide, magnesium oxide, or the like is used as the metal compound with a high refractive index, and calcium fluoride, fluoride is used as the metal compound with a low refractive index. Magnesium, sodium fluoride, silicon oxide or the like is used.

  The holding layer 45 is a layer for holding the glass beads 47A (glass bead layer 47). For example, a polyethylene resin, a polyester resin, an acrylic resin, a silicone resin, a fluororesin, a polyamide resin, a polyvinyl alcohol type is used. It is formed of a thermoplastic resin such as a resin, a polyurethane resin, a polyolefin resin, a polycarbonate resin, or a polysulfone resin. The holding layer 45 is formed as a thin layer that can hold the glass beads 47 </ b> A away from the support layer 44.

  The support layer 44 is formed of a film-like sheet such as a polyester resin, a polyolefin resin, a cellulose resin, or an acrylic resin.

  The second pressure-sensitive adhesive 42 is made of a rubber-based pressure-sensitive adhesive, a polyester-based pressure-sensitive adhesive, an acrylic pressure-sensitive adhesive, or a urethane-based pressure-sensitive adhesive, and has transparency. Before the protective seal S2 is affixed, the back surface of the second adhesive 42 is covered with a release paper (not shown). By peeling the release paper and exposing the second adhesive 42, the protective seal S2 is removed. The second adhesive 42 can be attached to the seal seal S 1, the first substrate case 10, and the second substrate case 20.

  The adhesive strength between the seal seal S1 and the side wall 104 of the first substrate case 10 and the bottom plate 200 of the second substrate case 20 (mainly, the adhesive strength against tensile shear or peeling tension; hereinafter referred to as “first adhesive strength”) is: It is greater than or equal to the adhesive strength between the seal seal S1 and the protective seal S2 (mainly, adhesive strength against tensile shear or peeling tension; hereinafter referred to as “second adhesive strength”). Here, “adhesive strength” means an object to be bonded by the first pressure-sensitive adhesive 32 or the second pressure-sensitive adhesive 42 (for the first pressure-sensitive adhesive 32, the first base material 31 and the side wall 104 of the first substrate case 10 or The bottom plate 200 of the second substrate case 20 or the second pressure-sensitive adhesive 42 refers to the stress required to separate the first base material 31 and the second base material 41). Therefore, when pulling with the protective seal S2 positioned on the front side, the protective seal S2 is peeled off from the seal seal S1 while the seal seal S1 and the substrate case X are adhered. Examples of the “peeling” here include interfacial destruction between the second adhesive 42 and the first base material 31 or the second base material 41, cohesive failure of the second adhesive 42, or interfacial fracture and cohesive failure. Any of the mixed destruction of may be sufficient. Thus, since the protective seal S2 is more easily peeled off than the seal seal S1, it becomes difficult to open the substrate case X without leaving any traces, and fraud can be suppressed.

  The cohesive force (strength) of the first base material 31 is smaller than the first adhesive strength, the second adhesive strength, and the cohesive force of the side wall 103 and the bottom plate 200. Therefore, if it pulls with the protective seal | sticker S2 located completely on the front side, the 1st base material 31 will destroy a material. It is not easy to restore the destroyed first base material 31 to such an extent that it is difficult to distinguish. Therefore, cheating can be suppressed.

  When such a fraud prevention seal S is irradiated with light of a predetermined wavelength, the light incident on the glass beads 47A not covered with the second printed layer 43 is refracted and becomes return light to the outside on the surface side. As a result, the color of the reflective layer 46 is emphasized, and an optical pattern is generated that has a brighter color than the color that can be seen under natural light (see FIG. 10B) (see FIG. 10C). On the other hand, since the refracted return light is blocked or absorbed by the second print layer 43 from the glass beads 47A covered with the second print layer 43, it does not return to the outside or is attenuated and returns. (See FIG. 10 (c)). Thus, a contrast is generated between the region where the second print layer 43 is present and the region where the second print layer 43 is not present. Therefore, under the light of a predetermined wavelength, the second printed layer 43 can be clearly observed, that is, the second identification information d2 attached to the protective seal S2 can be confirmed. Therefore, the authenticity of the gaming machine 1 to which the anti-tampering seal S is attached depends on the presence or absence of the second printed layer 43, the presence or absence of breakage / peeling of the second identification information d2, and the correctness of the second identification information d2. Can check and inspect fake. In the present embodiment, the second printed layer 43 is formed of ink made of a raw material that is transparent to light of a normal wavelength and transmits almost all of the second printed layer 43. It is difficult to notice that the second print layer 43 is displayed on the protective seal S2 and the second identification information d2 is attached. Therefore, fraudulent traces are easily left.

  In addition, when the reflection layer 46 is adjusted to a predetermined light transmittance, an optical pattern is not generated with natural light having a normal wavelength, and an optical pattern can be generated only when irradiation light with a predetermined wavelength is irradiated. It is. In this case, since the second printed layer 43 is displayed on the protective seal S2 and it is difficult to notice that the second identification information d2 is attached, it becomes easier to leave an improper trace.

  Further, since the optical pattern is a pattern having a specific color determined by the light refraction by the glass beads 47A and the light interference action by the reflection layer 46, the optical pattern is a tamper-proof seal S (protective seal S2). It is possible to determine whether or not the main control board unit UN1 is genuine by visually checking whether the pattern is a unique pattern in relation to the irradiation light). That is, when the protective seal S2 is irradiated with irradiation light (visible light) of a predetermined wavelength and a specific optical pattern is generated, it is determined that the main control board unit UN1 is authentic, while the specific optical pattern If a pattern different from the above is generated or an optical pattern is not generated, it is determined that the main control board unit UN1 is a fraudulent fraud, and an illegal act can be found.

  When adjusting the material, size, arrangement, etc. of the glass beads 47A, adjusting the thickness, material, transmittance, etc. of the reflective layer 46, adjusting the reflective layer 46 to a single layer or a multilayered layer The optical pattern with respect to the wavelength of the irradiation light (visible light) can be changed, and the adjustment thereof can be performed only by a precise manufacturing process. Therefore, it is almost impossible to forge the protective seal S2, and it is possible to prevent forgery. Furthermore, since a genuine protective seal S2 that cannot prevent counterfeiting and produces a unique optical pattern is attached to the main control board unit UN1, it is possible to reliably find the main control board unit that has been tampered with. And in turn can prevent fraud.

  When the anti-tampering seal S described above is affixed to the substrate case X of the main control board unit UN1, a so-called quality assurance function indicating that the main control board unit UN1 is genuine is exhibited and fraud Can contribute to the discovery and suppression. In order to discover fraudulent acts, the damage state and positional relationship of the seal seal S1 and the protective seal S2 are inspected and inspected by visual inspection or the like, and further, the protective seal is emitted by the above-described light emitting device that emits irradiation light of a predetermined wavelength. The surface of S2 is irradiated with light to inspect and inspect the peeled / teared state of the second printed layer 43 and the optical pattern.

  In addition, as described above, the first base material 31 is dissolved in the first pressure-sensitive adhesive 32 or the second pressure-sensitive adhesive 42, and the petroleum-based solvent that invalidates the adhesive action of the first pressure-sensitive adhesive 32 or the second pressure-sensitive adhesive 42 is used. Contains chemicals that react and change color. Therefore, if the petroleum-based solvent is applied to the fraud prevention seal S in an attempt to remove the fraud prevention seal S from the gaming machine 1, the first base material 31 is discolored, leaving a trace of fraud (FIG. 11 (a)). FIG. 11 (b)). Moreover, in the present embodiment, since the first base material 31 is exposed, this petroleum-based solvent is applied to the first base material 31, and traces of fraud are likely to remain. Furthermore, in this embodiment, since this chemical is easily dissolved in a mixed liquid of a petroleum solvent and the second adhesive, when the petroleum solvent is applied to the fraud prevention seal S and penetrates into the second adhesive, The chemical contained in the first base material 31 is dissolved from the first base material 31 into the mixed solution. As a result, the exposed portion of the first base material 31 is darker in color, and as shown in FIG. 11C, when the protective seal S2 is peeled off, the exposed portion of the first base material 31 and Contrast is generated between the portion covered with the protective seal S2. Furthermore, since the liquid mixture and the chemicals react and change color, the discolored chemicals also adhere to the protective seal S2, leaving a trace of fraud. Then, when the seal seal S1 and the protective seal S2 including the first base material 31 are discolored in this way, reuse becomes difficult and fraud is suppressed.

(Other embodiments)
The fraud prevention seal S of the first embodiment described above is attached to the opening / closing portion of the substrate case X, in other words, across the first substrate case 10 and the second substrate case 20. The pasting location is not limited to this, and may be either the surface 100A of the top plate 100 of the first substrate case 10 or the bottom surface 200B of the bottom plate 200 of the second substrate case 20. Furthermore, the place where the tamper-proof seal S is attached may not be the substrate case X but the insulating substrate D of the main control substrate A, an electronic component such as a CPU, or the like.

  Further, the seal seal S1 is attached only to one substrate case (for example, the side surface 104A of the side wall 104 of the first substrate case 10), and the protective seal S2 is attached to the other substrate case (for example, the second substrate). It can also be made to stick on the bottom face 200B) of the bottom plate 200 of the case 20. On the other hand, the seal seal S1 is pasted from one substrate case (for example, the side surface 104A of the side wall 104 of the first substrate case 10) to the other substrate case (for example, the bottom surface 200B of the bottom plate 200 of the second substrate case 20). The protective seal S2 can be attached to only one substrate case (for example, the side surface 104A of the side wall 104 or the bottom surface 200B of the bottom plate 200) from the seal seal S1.

  Moreover, in Embodiment 1, both the seal seal S1 and the protective seal S2 have the same rectangular shape, but these shapes are not limited to this, and may be other shapes such as a circle and a star. Furthermore, the shape of the seal seal S1 and the shape of the protective seal S2 may be different. In Embodiment 1, the protective seal S2 covers the entire seal seal S1, but the range in which the protective seal S2 covers the seal seal S1 is not limited to this. The protective seal S2 only needs to cover at least the portion of the seal seal S1 to which the first identification information d1 is attached. This is for preventing deterioration of the first identification information d1. In the first embodiment, the protective seal S2 is attached to the substrate case X as an adherend in a state of protruding from the entire circumference of the seal seal S1, but is in a state of protruding from a part of the seal seal S1. Can be attached to the substrate case X which is an adherend.

  Furthermore, although the 1st base material 31 consists of Japanese paper, such as an additional paper, and is a single | mono layer structure as a whole, the material and structure of the 1st base material 31 are not restricted to this. In addition, an IC chip is embedded in the first base material 31, and information (for example, third identification information d3 including a game shop code, a second management number, etc.) and the first identification described above are included in the IC chip. The fraud prevention seal S can be managed by a combination of the information d1 and the second identification information d2.

  Further, the structure, shape, and material of the substrate case X are not limited to those in the first embodiment, and may be appropriately designed. The same applies to the protective seal S2. For example, the reflective layer 46 may be formed between the holding layer 45 and the second base material 41. In this case, the reflective layer 46 is formed at a position where the irradiation light irradiated to the glass beads 47A is focused. Also in this case, the material, size, arrangement, etc. of the glass beads 47A are adjusted, the thickness, material, transmittance, etc. of the reflective layer 46 are adjusted, or the reflective layer 46 is a single layer or When the layer is adjusted to have a multilayer structure, a specific optical pattern for the wavelength of irradiated light (visible light) can be generated.
