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.

To achieve this object, the first invention is a gaming machine comprising a control board unit formed with a control board and a board housing case for housing the control board, wherein the board housing case comprises: It includes a box body of a substantially rectangular parallelepiped shape for accommodating the control board, and the projecting member for attaching an identification seal identifying the control board unit, the previous SL identification seal, a number of fine glass which is aligned A holding layer embedded with a part of the beads exposed; a printed layer printed on the exposed surface side of the plurality of glass beads; provided on the holding layer side; anda reflective layer for reflecting the illumination light of a predetermined wavelength irradiated from the side of the exposed surface, wherein the box body includes a sidewall insertion hole, said projection member is inserted into the insertion hole And at the inserted part In the state of being fixed to the inner surface of the insertion hole, a groove that protrudes to the outside of the side wall and that protrudes to the outside of the side wall of the projecting member is formed across the projecting direction. in protruding portion, wherein said identification seal the across and outside the region and the groove than the inner region than the groove is Ri attached taken.

  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. 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, it is possible to find evidence of fraudulent acts on the identification seal.

  Furthermore, the attachment part protrudes outside the accommodating part, and the groove | channel which cross | intersects the said protrusion direction is formed across. Therefore, when the weight of the vertical component is applied to the mounting portion for the purpose of extracting the identification seal, the mounting portion is broken from the groove. When the attachment portion is folded, the identification seal is scratched along the cut surface. That is, the structure of the identification seal is deformed. This deformation of the identification seal cannot be completely repaired. Therefore, the identification sticker attached to the control board unit cannot be reused as a genuine identification sticker. In order to make it difficult to cut the mounting portion so that the identification seal is not scratched (for example, the side surface of the identification seal is bent so as to approach the housing portion), the rotational strength of the mounting portion with respect to that direction is set. It is desirable to make it the largest.

  The board housing case has a housing part for housing the control board and an attaching part for attaching an identification seal for identifying the control board unit. The mounting portion protrudes outside the housing portion, and a groove that intersects the protruding direction is formed across the mounting portion. On the other hand, the identification seal is arranged across the region outside the groove and the region inside, and the holding layer embedded with a part of a large number of aligned fine glass beads exposed, and a large number of glasses A printed layer printed on the exposed surface side of the beads, and a reflective layer provided on the holding layer side and reflecting the irradiation light of a predetermined wavelength irradiated from the exposed surface side of many glass beads. . Therefore, it is possible to find evidence of fraud.

And a control board unit having a structure in which an effect control board for controlling an effect lamp, a liquid crystal display panel, and a speaker is housed in a case in order to enhance the visual effect and the sound effect described above, and others A control board unit having a structure in which various control boards are housed in a case is also attached.

  As shown in FIG. 1A, when the inner frame 1c and the front door 1d are locked to the machine frame 1a, the control board units are accommodated in the gaming machine 1 and viewed from the outside. Can not be.

  Next, the structure of the above-described control board unit will be described with reference to FIGS. The control board unit that houses the main control board described above, the control board unit that houses the production control board, and the control board unit that houses various other control boards also have basically the same structure for preventing fraud. Since it is provided, the structure of the control board unit UN that houses the main control board will be described as a representative.

  2 and 3 are perspective views showing the external structure when the control board unit UN is viewed from two directions. FIG. 2 is a view from one direction, and FIG. 3 is a view from the other direction. FIG. 4 is an exploded perspective view of the control board unit UN.

  2 and 3, the control board unit UN includes a rectangular box-shaped first board case B and a tray shape that form a board housing case for housing the main control board A (see FIG. 4) by fitting together. Second substrate case C. Both the first substrate case B and the second substrate case C are formed of a so-called hard transparent plastic material such as a transparent acrylic resin or polycarbonate resin. Therefore, the accommodated main control board A can be visually recognized through the first board case B or the second board case C.

  As shown in FIG. 4, the main control board A is an insulating circuit board D made of glass epoxy resin or the like and provided with pattern wiring. On the insulating board D, an integrated circuit device such as a CPU, a ROM, etc. And a plurality of external connection sockets Sa to Sg mounted on the power supply cable for supplying power to the main control board A as the external connection sockets Sa to Sg. A socket to which is connected, a socket to which a connector attached to a flat cable for signal transmission is connected, and the like are mounted. The CPU executes a program stored in the ROM, thereby performing control for a game operation or the like.

  The first substrate case B has a rectangular box-shaped base portion 2b composed of a rectangular top plate portion 2a and side walls (reference numerals omitted) extending from the top plate portion 2a and hanging down. Further, as shown in FIG. 4, a plurality of (four in this embodiment) screw holes 2c penetrating toward the second substrate case C side are formed at one end of the base portion 2b. . Furthermore, a first fitting projection 2d is formed at one end of the base portion 2b, and this fitting projection 2d is inserted into a fitting hole 3a formed in the side wall 3h of the second substrate case C. At the same time, it opposes the protrusion 3i provided to project outward from the edge of the fitting hole 3a (in the present embodiment, it opposes the vertical direction). The fitting protrusion 2d is formed with a first fixing hole 2j through which a fixing member K made of a rivet described later is inserted. Further, the first substrate case B, which will be described later, is connected to the second substrate case C from the first fixing hole 2j on the surface of the fitting projection 2d that faces the projection 3i and the surface that does not face the projection 3i. On the other hand, cut-off guide grooves 2k and 2l are formed across the first fitting protrusion 2d in a direction perpendicular to the sliding direction (the disassembly direction of the substrate housing case, the axial direction of the rail portions 3b and 3c). . The cut-off guide groove 2k makes it easy for the fitting protrusion 2d to be broken when a load of a component in the vertical direction with respect to the fitting protrusion 2d acts on the fitting protrusion 2d.

  The rectangular box-shaped base portion 2b of the first substrate case B is further formed with a table-shaped base portion 2e extending outward, and is mounted on the main control board A on the base portion 2e. A plurality of loose fitting holes ha to hg for loosely fitting the external connection sockets Sa to Sg are formed. When the main control board A is attached to the lower surface of the pedestal 2e in the manufacturing process, the external connection sockets Sa to Sg loosely fitted in the loose fitting holes ha to hg project to the upper surface side of the pedestal 2e, and the projections By connecting the power supply cable and the connector attached to the signal transmission flat cable to the external connection sockets Sa to Sg, the power supply device provided in the pachinko machine 1 and other various devices, etc. It is designed to be wired between.

  Further, a fitting portion 2g having a linear fitting groove 2f is formed on the side wall of the base portion 2e (see FIGS. 3 and 4), and on the side wall of the first substrate case B opposite to the base portion 2e. Is formed with a fitting portion 2h having a linear fitting groove (reference numeral omitted) (see FIG. 2). And the linear rail parts 3b and 3c (refer FIG. 4) are formed in the opposing side wall of the 2nd board | substrate case C, and the rail part 3b is fitted in the fitting groove 2f of the fitting part 2g. The first and second substrate cases B and C are integrally combined by fitting the rail portion 3c into the fitting groove (reference numeral omitted) of the fitting portion 2h.

  A plurality of pedestals 3e for placing the main control board A are formed on the rectangular bottom face 3d of the second board case C, and are formed at predetermined positions on the side walls of the first board case B. A second fitting protrusion 3f to be inserted into the fitting hole 2i (see FIG. 2) is formed. The rectangular bottom surface 3d of the second substrate case C has a plurality (four in this embodiment) of screw receiving portions 3g facing the above-described screw holes 2c formed in the first substrate case B. The female screw grooves communicating with the individual screw holes 2c are formed in the individual screw receiving portions 3g.

  On the other hand, a second fitting inserted into a first fitting protrusion 2d (see FIG. 2) formed at a predetermined position of the first substrate case B is formed on the rectangular side wall 3h of the second substrate case C. A joint hole 3a is formed. And the protrusion part 3i is formed in the surface of the side wall 3h below the opening edge part of the 2nd fitting hole 3a toward the outer side. The protrusion 3i faces the first fitting protrusion 2d in a state in which the control board unit UN is assembled, and is a surface (upper surface in the present embodiment) facing the first fitting protrusion 2d. ) Is attached with an identification seal LB.

  Similarly, a second fixing hole 3j into which a fixing member made of a rivet is inserted is formed at a position facing the first fixing hole 2j of the protrusion 3i, and the fixing member K is the first fixing hole K. 1 fitting protrusion 2d and protrusion 3i, in other words, the first substrate case B and the second substrate case C are firmly fixed. Here, since the cross section of the first fixing hole 2j and the cross section of the second fixing hole 3j are the same as the cross section of the portion inserted into the holes 2j and 3j of the fixing member K, the first substrate case B and the second substrate case C are also restrained by the fixing member K. The identification seal LB is penetrated by the fixing member K.

  Further, a first substrate case B, which will be described later, is disposed on the second substrate case C side from the second fixing hole 3j on the surface facing the first fitting protrusion 2d and the surface not facing the protrusion 3i. Cut-off guide grooves 3k and 3l are formed across the protrusion 3i in a direction orthogonal to the direction of sliding with respect to the case C (the disassembling direction of the substrate housing case, the axial direction of the rail portions 3b and 3c). The printing layer 4 of the identification seal LB is attached across the cut-out guide grooves 3k and 3l in the sliding direction. In this embodiment, the cut-off guide grooves 2k, 2l, 3k, and 3l are provided in parallel to the vertical direction. Due to the cut-out guide grooves 3k and 3l, the protrusion 3i is easily broken when a load of a component in the vertical direction with respect to the protrusion 3i acts on the protrusion 3i.

  Further, the fitting portions 2g and 2h and the rail portions 3b and 3c are fitted (the fitting portions 2g and 2h are placed on the rail portions 3b and 3c), and the first fitting protrusion 2d and the first In the state in which the fitting hole 3a is fitted, the distance between the first fitting protrusion 2d and the protruding portion 3i is longer than the thickness of the identification seal LB. That is, as will be described later, even if the first substrate case B is slid in the fitting direction on the second substrate case C, the printed layer 4 formed on the resurface of the identification seal LB is the first fitting. There is no contact with the protrusion 2d. Further, the first fitting protrusion 2d protrudes outside the second substrate case C in a state where the first substrate case B and the second substrate case C are completely fitted and sealed, and the protrusion This part completely covers the identification seal LB pasted on the protrusion 3i.

  The first fitting protrusion 2d, the first fitting hole 2i, the second fitting hole 3a, and the second fitting protrusion 3f are arranged so that the first board case B and the second board case C are in a predetermined direction. When it slides, the corresponding ones are formed at positions where they are fitted (inserted) or unfitted (pulled out). Here, “predetermined direction” corresponds to a state where the fitting portions 2g and 2h and the rail portions 3b and 3c are fitted (the fitting portions 2g and 2h are placed on the rail portions 3b and 3c). The fitting protrusions 2d and 3f and the fitting holes 3a and 2i are fitted or released (referred to as the axial direction of the fitting groove 2f or the axial direction of the rail portions 3b and 3c). That is, the fitting protrusion 2d and the fitting hole 3a, and the fitting protrusion 3f and the fitting hole 2i face each other in the fitting direction, and their axial directions all coincide.

  Further, the cross section of the base portion of the fitting protrusion 2d and the cross section of the fitting hole 3a, and the cross section of the base portion of the fitting protrusion 3f and the cross section of the fitting hole 2i are the same. When 2d and 3f are fitted (inserted) into the fitting holes 3a and 2i, the fitting protrusions 2d and 3f are restrained by the fitting holes 3a and 2i. Therefore, the relative movement of the substrate cases B and C is limited to the sliding in the predetermined direction. Accordingly, when the corresponding fitting protrusions 2d and 3f and the fitting holes 3a and 2i are fitted (inserted), the board housing case is disassembled (disassembled) without destroying any of the board cases B and C. In order to achieve this, there is no choice but to slide in the predetermined direction (the axial direction of the fitting protrusions 2d and 3f or the fitting holes 3a and 2i).

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. 4 from below. 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, an identification seal LB is pasted on the surface (the upper surface in FIG. 4) of the protrusion 3i of the second substrate case C from above the second fixing hole 3j and the cut-off guide groove 3k.

  Next, in a state where the main control board A is attached to the lower surface of the first board case B, the first board case B is combined so as to cover the second board case C. Here, after fitting the fitting portions 2g, 2h formed on the first substrate case B and the rail portions 3b, 3c formed on the second substrate case C, the rail portions 3b, 3c Then, the fitting portions 2g and 2h are slid. Then, the first substrate case B is formed in the second substrate case C in the fitting hole 2i (see FIG. 2) formed in the first substrate case B while sliding with respect to the second substrate case. The fitting projection 3f is fitted, and the fitting projection 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. 2 and 3, the fitting protrusion 3f and the fitting hole 2i are fitted, the fitting protrusion 2d and the fitting hole 3a are fitted, and the first board case B is fitted. By fitting the formed fitting portions 2g and 2h with the rail portions 3b and 3c formed on the second substrate case C, the first and second substrate cases B and C are connected to the rail portions 3b and 3c. Relative movements other than in the length direction are combined firmly in a restricted state. The first and second substrate cases B and C are sealed, and the insulating substrate D is placed on the pedestal 3e. That is, as shown in the cross-sectional view of the main part in FIG. 6, the main control board A is housed in a sealed board housing case in a stable state.

  Further, as described above, when the fitting portions 2g and 2h are slid with respect to the rail portions 3b and 3c, the distance between the first fitting protrusion 2d and the protrusion 3i is secured longer than the thickness of the identification seal LB. Has been. Therefore, peeling of the printed layer 4 from the glass bead layer due to the contact between the printed layer 4 of the identification seal LB and the first fitting protrusion 2d during the slide can be prevented. Further, as described above, when the first substrate case B and the second substrate case C are completely sealed, the first fitting protrusion 2d completely covers the identification seal LB attached to the protrusion 3i. The identification seal LB is protected from contamination by external elements (cigarette smoke, dust and dirt). Therefore, it is possible to suppress the quality deterioration of the identification seal LB. This effect is particularly useful in pachinko parlors and the like because tobacco smoke is likely to be generated.

  As described above, when the first and second substrate cases B and C are combined and the fitting protrusions 2d and 3f and the fitting holes 3a and 2i are respectively fitted, the cross-sectional view of FIG. As shown in the sectional view taken along the screw receiving portion 3g), a plurality of screw holes 2c formed in the first substrate case B and a plurality of screw receivers formed in the second substrate case C are shown. The parts 3g communicate with each other. Therefore, next, the fixing screws Na to Nd are inserted into the individual screw holes 2c and screwed into the individual screw receiving portions 3g, so that the first and second substrate cases B and C are more firmly integrated. Can be Further, by sealing the heads of the fixing screws Na to Nd 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 are illegally disassembled. Can not be.

  Further, as described above, when the first and second substrate cases B and C are combined and the fitting protrusions 2d and 3f and the fitting holes 3a and 2i are respectively fitted, the first fixing hole 2j and the first fixing hole 2j 2 fixed holes 3j. Therefore, for example, a fixing member K made of rivets is inserted from the first fixing hole 2j, and is inserted into the second fixing hole 3j while breaking the identification seal LB, so that the tip end of the fixing member K is protruded from the protrusion 3h. Make it protrude. Then, when the protruding portion is crushed by using a predetermined tool (for example, a rivet hammer), the first fitting protrusion 2d of the first substrate case B is formed by the head portion originally provided with the rivet and the crushed portion. The protrusion 3i of the second substrate case C is firmly fixed (integrated). This completes the control board unit UN. In this way, a hole penetrated by the fixing member K is formed in the identification seal LB of the control board unit UN. Therefore, for example, even if the identification seal LB can be removed by some method, the identification seal LB cannot be diverted to another control board unit on which the fraudulent main control board A is installed. That is, the reuse of the identification seal LB is prevented by the damaged portion of the identification seal LB formed in the manufacturing process.

  Further, the printed layer 4 of the identification seal LB straddles the cut-out guide grooves 2k, 2l, 3k, and 3l, that is, a portion exposed to the outside of the surface to which the identification seal LB is attached and a portion accommodated in the inside. Attached across the boundary. Therefore, if the fixing portion (the first fitting protrusion 2d and the protrusion 3i) by the fixing member K is cut off for the purpose of releasing the fixation between the first substrate case B and the second substrate case C, the protrusion Since 3i is folded at the cut-off guide grooves 3k and 3l, the structure of the identification seal LB is deformed (the identification seal LB is damaged). Therefore, if the deformation pattern of the structure that occurs in this case is known in advance, the evidence of the cutting off operation of the fixed part is found by the deformation of the structure of the identification seal LB that inevitably occurs irreversibly by the cutting off operation. be able to. That is, since a specific deformed portion is formed in the identification seal LB in the course of the fraudulent act, it is impossible to divert the identification seal LB acquired via the cut-off act. In short, reuse of the identification seal LB is prevented. In order to easily find the trace of the damaged portion, it is desirable that the printed layer 4 is disposed on the cut-out guide grooves 3k and 3l.

Next, the structure of the identification seal LB described above will be described.
FIG. 8 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. 8, the identification seal LB has a printed layer 4, a glass bead layer composed of a large number of fine glass beads 5 arranged in alignment, a reflective layer 6, a holding layer 7, and a substrate 8. The base material 8 includes a support layer 9 and an adhesive layer 10.
The printed layer 4 is the upper surface side (the side irradiated with irradiation light described later) of the identification seal LB, and the base material 8 is the back surface side that is attached to the surfaces of the protrusions 2d and 3f shown in FIGS. Yes.

  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. It is arranged on the holding layer 7 in a state of being laid out in an orderly two-dimensional direction (planar shape). 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 formed of ink on which predetermined characters, figures, patterns, or the like are printed. What is represented by the printing layer 4 includes identification information for identifying the control board unit UN, information indicating the quality assurance of the manufacturer, information such as a trademark, and the like. When the printing layer 4 displays identification information for identifying the control board unit UN, the identification information is uniquely associated with the management number (or identification number) given to the CPU or ROM of the main control board A described above. be able to. In this case, 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. As a method of giving a management number to a CPU or the like, there is a method of directly engraving a management number on the surface of the CPU or the like, a method of sticking a seal with a management number, a method of storing a management number in a storage device, or the like. is there.

  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. And the back surface of the adhesion layer 10 is coat | covered with the release paper which is not shown in figure, peels off the release paper, and sticks the exposed adhesion layer 10 on the surface of the protrusion part 3i shown in FIGS. The sticking of the identification seal LB to the protrusion 3i is performed.

  When the identification seal LB described above is pasted on the protrusion 3i, 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 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.

  In addition, you may form the identification seal | sticker LB of this Embodiment 1 described above in circular shapes, such as a perfect circle and an ellipse, as shown in FIG. 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. . However, since the shape of the identification seal LB is not particularly limited, it may be a rectangular shape such as a rectangle or a square, or another shape.

  In the first embodiment, the substrate housing case is sealed and opened by sliding the substrate cases B and C slidably fitted in the fitting portions 2g and 2h and the rail portions 3b and 3c. The (case sealing) structure of the storage case 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. In this case, the substrate housing case may not have a hinge, and the lid-shaped first substrate case B may be simply fitted from the opening side of the rectangular substrate-shaped second substrate case C. 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 the first embodiment, the cross-section of the fitting protrusion and the cross-section of the fitting hole are the same, but they are not necessarily the same. In the first embodiment, the cross-sectional shape of the fitting protrusion and the cross-sectional shape of the fitting hole are both rectangular, but these cross-sectional shapes are not particularly limited.

  In the first embodiment, the substrate housing case has two fitting structures, and the identification seal LB is pasted using one of the fitting structures. Even if LB is stuck, the identification seal LB may be stuck using the other fitting structure. Furthermore, in this embodiment, the identification seal LB is pasted on the surface of the protrusion 3i that faces the first fitting protrusion 2d, but the surface of the first fitting protrusion 2d that faces the protrusion 3i. The identification seal LB may be attached. In the present embodiment, the identification seal LB is attached using a fitting structure, but the identification seal LB may be attached at a portion other than the fitting structure. For example, the first fitting protrusion 2d and the second fitting hole 3a are not structured to be fitted, and the second fitting hole 3a is notched from the upper surface of the side wall 3h, and the first fitting The protrusion 2d may simply be inserted into the second fitting hole 3a and protrude from the second substrate case C.

  Further, in the present embodiment, the identification seal LB is covered by the first fitting protrusion 2d and protected from external elements, but a structure in which the identification seal LB is not covered may be used. For example, the first fitting protrusion 2d does not protrude from the second substrate case C, or the protrusion 3i is not formed, and is pasted on the surface of the first fitting protrusion 2d, and the identification seal LB It may be a structure in which all of is exposed. In this case, since the identification seal LB can be attached at the end of the manufacturing process of the substrate housing unit UN, the reliability of the identification seal LB is reduced by damaging the printed layer 4 or the glass bead layer of the identification seal LB in the manufacturing process. Can be reduced.

  Furthermore, in the present embodiment, the fixing holes 2j and 3j are formed in advance, but only one of them may be formed or none of them may be formed. If both the holes 2j and 3j are formed, the substrate housing unit UN can be manufactured without damaging the first fitting protrusion 2d and the protrusion 3i. On the other hand, if neither of the holes 2j and 3j is formed, only the operation of driving the fixing member K is performed, and the operation of aligning the fixing member K with the fixing holes 2j and 3j can be omitted. Simplification can be achieved.

  Moreover, in this embodiment, although the part which attaches identification seal | sticker LB is all flat, the guide part along the external shape of identification seal | sticker LB may be formed, for example. In this case, since the relative positions of the fixing holes 2j and 3j with respect to the identification seal LB, that is, the damage position of the identification seal LB is stabilized, the prevention of fraud by the identification seal LB can be enhanced.

  Also in the identification seal LB of this embodiment, 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 single. When the layer is adjusted to a layer having a multilayer structure, a specific optical pattern with respect to the wavelength of the irradiated light (visible light) can be generated.
