  In the main control board case 30, the main control board 60 is fixed to the inner surface side of the case lid 50 with a screw or an adhesive, and the case lid 50 is integrated with the case body 40 by sliding along the long side direction. After that, the sealing block 46 provided in the case body 40 and the sealing slit 56 provided in the case lid 50 are aligned and irreversibly sealed by the J-shaped metal fitting 80. is there. As described above, the main control board case 30 accommodates an electronic component such as an IC chip attached on the mounting surface of the main control board 60 in an accommodation space surrounded by the case body 40 and the case lid 50. Further, from the sealing window 55 provided on the case lid 50, a part of the sealing seal 70 (hidden character string 73b and the like) is exposed to the outside.

  The case main body 40 is formed by molding a transparent polycarbonate resin, and has a rectangular main body bottom surface portion 41 and a pair of main body long wall portions 42 and 42 erected along each long side of the main body bottom surface portion 41 (see FIG. 3). Rail grooves 43 and 43 (see FIG. 3) for sliding the case lid 50 are formed along the long sides inside the long wall portions 42 and 42 of the main body. Further, on the outer surface of one main body long wall portion 42, hook portions 44, 44 for hooking the main control board case 30 on the back surface of the pachinko machine 20 are provided. Further, the case body 40 is formed with stopper walls 43a and 43a for stopping the case lid 50 that slides on the rail grooves 43 and 43 at the end of the rail grooves 43 and 43. Between these two stopper walls 43a, 43a, five sealing blocks 46, 46,... Are provided. The sealing block 46 has a cavity formed therein, and once the long leg portion 81 of the J-shaped fitting 80 is inserted into the cavity, the jaggedness formed in the long leg portion 81 even if the J-shaped fitting 80 is to be removed. A hook (not shown) is formed that engages with the protrusion 82 of the member to prevent movement in the extraction direction.

  The case lid 50 is formed by molding a transparent polycarbonate resin, and includes a rectangular lid bottom surface portion 51 and a pair of lid long wall portions 52 erected along the long sides of the lid bottom surface portion 51. , 52. Among these, a large number of heat radiating holes 51 a for releasing heat of the main control board 60 to the outside are formed in the lid bottom surface portion 51. In addition, the lid long wall portions 52 and 52 are formed with flange portions 53 and 53 (only one side is shown in FIGS. 2 to 4) to be fitted into the rail grooves 43 and 43 of the case body 40 and to be slid. ing. The flange 53 is provided with a plurality of connector windows 54 for exposing the connectors 64 of the main control board 60 and a seal window 55 for exposing a part of the seal seal 70. The peripheral surface of the sealing window 55 is an adhesive surface of the seal seal 70, but is roughened to form fine irregularities. Further, five sealing slits 56, 56,... Are provided on one short side of the case lid 50. Inside the sealing slit 56, a bridging portion (not shown) is formed on which the hook 83 formed in a bowl shape of the J-shaped fitting 80 is hooked when the J-shaped fitting 80 is inserted into the sealing slit 56. ing. Although not shown in the figure, the other short side of the case lid 50 is provided with a lid short wall portion. As a result, the case lid 50 has four sides of the lid bottom surface portion 51 and the lid long wall portions 52 and 52. The sealing slits 56, 56,... Are surrounded by the base short wall portion.

  The main control board 60 is obtained by mounting various electronic components on the surface (mounting surface) on the case lid 50 side of the printed wiring board 61 (see FIG. 4). As shown in FIG. 2, the mounted electronic component includes a CPU 62 that controls the entire pachinko machine 20, a ROM 63 in which various programs are recorded, and the like. On the main control board 60, a plurality of connectors 64 for electrically connecting various electronic components mounted thereon and external electronic components are also mounted. Further, the portion of the main control board 60 to which the seal seal 70 is bonded is roughened to form fine irregularities. The CPU 62 executes various processes in accordance with the program recorded in the ROM 63. For example, whether or not to shift to a special gaming state (so-called jackpot) advantageous to the player is determined based on the jackpot probability recorded in the ROM 63. Browse the table. Therefore, if this ROM 63 is replaced with an illegal ROM having a table with a very high probability of jackpot, an unreasonable prize ball will be obtained. Each electronic component is fixed to the back side of the mounting surface of the main control board 60 with solder.

  The seal seal 70 is a so-called hologram brittle seal, and as shown in FIG. 5, a seal body 73 having a hologram forming layer and a reflection layer over the entire surface, and a first adhesive formed on one surface of the seal body 73 Layer 71 and a second adhesive layer 72 formed on the other surface of the seal body 73. The first adhesive layer 71 is adhered to the flange 53 of the case lid 50, and the second adhesive layer 72 is the main control. The substrate 60 is adhered to the mounting surface side. The first adhesive layer 71 is not formed on the substantially square central portion 74 on one surface of the seal body 73. For the hologram forming layer of the seal body 73, an optical hologram photographing method is generally used in which interference fringes are formed using laser light. For example, a document on which a two-dimensional motif (in this embodiment, “ABCD” is repeatedly arranged as shown in FIG. 2) is prepared, and one of the laser beams branched into two is used as this document. Irradiated, the reflected light and the other branched laser light are made to interfere with each other, and the interference fringes are recorded on a photosensitive material, which is prepared as a hologram master by a press method. The seal seal 70 changes its color when the angle when viewed from the first adhesive layer 71 side is changed. However, the seal seal 70 has high security because it cannot be copied by simple copying or photography. Further, in the central portion 74 of the seal body 73, in addition to the hologram forming layer, a hidden character string 73b made of a laser coloring agent that can be read when irradiated with laser light, and a normal copying machine that cannot be read with the naked eye In this case, there is formed a lower-case letter string 73c composed of characters that are so small that they cannot be copied due to the resolution. The central portion 74 is exposed to the outside from a sealing window 55 formed on the flange portion 53 of the case lid 50. As a result, the hidden character string 73b and the ultra-small letter string 73c are exposed to the outside.

  The seal seal 70 is a hologram brittle seal. When the case lid 50 and the main control board 60 are separated from each other, the seal seal 70 is divided and attached to both of them, and a portion attached to the main control board 60 is a predetermined part. It appears as a pattern (here, a character pattern “opened”). As a result, it becomes obvious at a glance that the case lid 50 and the main control board 60 have been separated from each other, and since it cannot be restored to its original state, tampering is prevented. This type of hologram brittle seal is well known as disclosed in, for example, Japanese Patent Laid-Open Nos. 63-106780 and 7-219435.

  Next, a method for assembling the main control board case 30 will be described. First, the seal seal 70 is bonded to the flange 53 of the case lid 50. Here, the hidden character string 73 b of the seal seal 70 is bonded to the flange portion 53 of the case lid 50 through the first adhesive layer 71 so as to be exposed from the sealing window 55. Next, the main control board 60 is fixed to the inner surface side of the case lid 50 with a screw or an adhesive. Then, the main control board 60 is bonded to the second adhesive layer 72 of the seal seal 70. Then, the case lid 50 to which the main control board 60 is fixed is slid along the rail grooves 43 and 43 of the case main body 40 to be integrated. As a result, the sealing blocks 46 and the sealing slits 56 are aligned. Finally, the J-shaped metal fitting 80 is inserted into the sealing slit 56. Then, the hook portion 83 formed in a key shape of the J-shaped metal fitting 80 is hooked on a bridging portion (not shown) in the sealing slit 56, and the protrusion 82 of the long leg portion 81 is removed from the hook (not shown) in the sealing block 46. Engage so that it is impossible. As a result, the sealing block 46 and the sealing slit 56 are irreversibly sealed by the J-shaped metal fitting 80. Further, the hidden character string 73 b and the ultra-small letter string 73 c of the seal seal 70 are exposed from the seal window 55 of the case lid 50 to the outside.

  Next, the inspection of whether or not an illegal act has been performed on the main control board case 30 will be described. The person in charge of inspection first determines whether or not the sealing between the sealing block 46 and the sealing slit 56 has been illegally released. When this sealing is illegally released, there remains a trace that the connection between the sealing slit 56 and the case lid 50 is cut off, so whether or not the sealing is illegally released due to the presence or absence of this trace. Can be determined. Subsequently, it is determined whether or not the seal by the seal seal 70 has been illegally released. When the seal is illegally released, the seal seal 70 functions as a hologram brittle seal and is irreversibly destroyed, and a character pattern “opened” appears on the main control board 60 side. For this reason, it is possible to determine whether or not the seal by the seal seal 70 is illegally released based on the presence or absence of this character pattern. Here, in this embodiment, since the sealing window 55 is formed in the collar portion 53 of the case lid 50, the fraudulent person inserts some tool from the sealing window 55 to cheat the main control board 60. It is possible to work. However, since the seal seal 70 as a whole functions as a hologram brittle seal, when a tool is inserted through the sealing window 55, a part of the “opened” character pattern appears in the inserted portion.

  Further, whether or not the seal seal 70 has been replaced with a counterfeit seal is checked by checking whether or not the color changes depending on the viewing angle. If the color does not change even if the viewing angle is changed, the seal without the hologram forming layer is checked. Therefore, it can be determined that it is a forged seal. Further, it is inspected whether or not a predetermined character string (for example, unique identification information such as a serial number or an ID number) can be recognized by irradiating a portion where the hidden character string 73b is formed with laser light. If the received character string cannot be recognized, it can be determined that it is a forged seal. At this time, since the hidden character string 73b is not covered with the transparent resin of the case lid 50 and is exposed to the outside through the sealing window 55, recognition of the hidden character string 73b by the laser light is not hindered by the transparent resin. Can be determined with high accuracy. Further, it is examined whether or not a predetermined character string (for example, unique identification information such as a serial number or an ID number) can be recognized by enlarging a portion where the lowercase letter string 73c is formed with a magnifying glass or the like. If the determined character string cannot be recognized, it can be determined that the forged seal. At this time, the lowercase letter row 73c is not covered with the transparent resin of the case lid 50 and is exposed to the outside from the sealing window 55, so that the enlarged image when enlarged is not obstructed by the transparent resin, and is accurate. Can be determined.

  Here, the correspondence between the components of the present embodiment and the components of the present invention will be clarified. The case lid 50 of the present embodiment corresponds to the substrate case constituent of the present invention, the flange 53 corresponds to the constituent edge, the lid bottom 51 corresponds to the constituent bottom, and is a hologram brittle seal. A seal seal 70 as a whole is a part to be destroyed and at the same time corresponds to a visual confirmation part (a kind of authenticity confirmation part), and a hidden character string 73b corresponds to an irradiation confirmation part (a kind of authenticity confirmation part). 55 corresponds to an irradiation window. Note that the lowercase letter string 73c is a kind of authenticity confirmation unit.

  According to the present embodiment described in detail above, the case lid 50 and the main control board 60 are separated from each other if fraud is attempted on the main control board 60. In this case, a seal that is a hologram brittle seal is used. Since the seal 70 is irreversibly broken, an attempt to return the seal seal 70 again does not return. Therefore, even if an unauthorized person replaces the parts such as the ROM 63 on the main control board 60 with an unauthorized part or replaces the main control board 60 with an unauthorized control board, the inspector can see the state of the seal seal 70. It is easy to detect that cheating has been done.

  Further, if the sealing seal 70, which is a hologram brittle seal, is visually observed from the outside, the authenticity can be easily confirmed without opening the main control board case 30. In addition, the hologram pattern cannot be counterfeited by a copying machine, a photo shoot or the like, so that security is high.

  Further, since the hidden character string 73b cannot be known unless it is irradiated with laser light, the security is high. Since the hidden character string 73b is exposed to the outside from the sealing window 55 of the case lid 50, the laser light is not hindered by the case lid 50, so that the authenticity can be accurately confirmed. .

  Further, since the seal seal 70 itself corresponds to a hologram brittle seal which is a broken portion, the broken portion is connected over the entire circumference of the sealing window 55 (the sealing window 55 and the mounting location of the ROM 64 of the main control board 60 are connected). A region P (see FIG. 1) crossing the line is formed. For this reason, when a fraudulent person inserts some tool from the seal window 55 toward the chip mounting location such as the ROM 63, the hologram brittle seal is destroyed, and the person inspecting the state of the hologram on the seal seal 70. You can easily discover that fraud has been done.

  Further, since the seal seal 70 is affixed using a flange 53 (a portion near the connector window 54) formed so as to substantially match the main control board 60 in the case lid 50, separately, There is no need to make a location for attaching the seal seal 70.

  Further, since the peripheral surface of the sealing window 55 to which the sealing seal 70 is bonded and the surface of the main control board 60 to which the sealing seal 70 is bonded are roughened in the case lid 50, the case lid 50 and Since the adhesive force between the seal seal 70 and the adhesive force between the main control board 60 and the seal seal 70 is increased, it is more difficult to perform an illegal act such as replacement of the main control board 60.

  Further, the seal seal 70 has a lowercase letter column 73c. However, the lowercase letter column 73c cannot be identified with the naked eye and cannot be counterfeited due to resolution, even if it is counterfeited by a copying machine or a photo shoot. .

  The embodiment of the present invention is not limited to the above-described embodiment, and it goes without saying that various forms can be adopted as long as it belongs to the technical scope of the present invention.

  For example, in the above-described embodiment, the main control board case 30 is shown as an example of the board case of the gaming machine of the present invention. However, for example, a payout control board case that houses a payout control board, and a display control board that houses a display control board The present invention may be applied to a case, a lamp control board case that houses a lamp control board, or a voice control board case that houses a voice control board. In these cases, the same effect as the above-described embodiment can be obtained.

  In the above-described embodiment, the hologram brittle seal (which is also a portion to be destroyed) is adopted as the visual confirmation portion, but a brittle seal in which no hologram is formed may be adopted as the visual confirmation portion.

  Furthermore, in the above-described embodiment, the hidden character string 73b created by the laser color former that can be read by the laser light is used as the irradiation confirmation unit, but the hidden character string created by the photochromic ink that can be recognized by the UV light is adopted. May be.

  Furthermore, in the above-described embodiment, the unique identification information (serial number, product name, etc.) may be laser-marked so as to penetrate the case lid 50, the seal seal 70, and the main control board 60. Good. In this way, if an unauthorized act of replacing the legitimate seal seal 70 or the main control board 60 with a counterfeit product is made, the inherent identification information that was originally marked cannot be read. can do.

  In the embodiment described above, the hologram brittle seal is adopted as the portion to be destroyed, but instead, the color of the seal seal 70 changes irreversibly when the case lid 50 and the main control board 60 are separated. May be adopted. In this way, it is possible to easily recognize that the case lid 50 and the main control board 60 are separated due to the color change. As a specific configuration, for example, a coloring microcapsule and a developer are sealed in a portion of the seal seal 70 that is peeled off when the case lid 50 and the main control board 60 are separated from each other. When the color developing microcapsules are broken, the color developing agent in contact with the developer may cause color development.

  Alternatively, as a portion to be destroyed, a transmitting circuit is formed as a predetermined electric circuit in a portion of the seal seal 70 that is peeled off when the case lid 50 and the main control board 60 are separated, and when the peeled off The transmission circuit may be disconnected and transmission may be interrupted. By doing this, it is possible to easily confirm whether or not the case lid 50 and the main control board 60 are separated by checking whether or not the transmission circuit is disconnected.

  Furthermore, instead of the seal seal 70 of the above-described embodiment, a seal seal 170 shown in FIG. 6 may be adopted. 6A is a plan view of the seal seal 170, and FIG. 6B is a cross-sectional view taken along the line BB. The seal seal 170 includes a seal body 173 having a shape in which a plurality of circumferential bands 173b are formed around a disk 173a and each circumferential band 173b is connected by a plurality of linear portions 173c in the diameter direction, and one of the seal bodies 173 A first adhesive layer 171 formed on the surface and a second adhesive layer 172 formed on the other surface of the seal body 173, and the first adhesive layer 171 is bonded to the flange portion 53 of the case lid 50, The second adhesive layer 172 is bonded to the mounting surface side of the main control board 60. The seal body 173 is also a brittle seal having a hologram forming layer and a reflective layer over the entire surface. Further, a character string 174 (here, “SECURITY”) separate from the seal body 173 is formed on the circumferential band 173b and the straight line portion 173c of the seal body 173. Here, each character of the character string 174 partially protrudes outward from the circumferential band 173b. The seal seal 170 is sandwiched between the mount 178 and the transparent sheet 179 before use, and the mount 178 is in contact with the second adhesive layer 172 but is only bonded with a very weak force, and is transparent. The sheet 179 is bonded to the first adhesive layer 171 with a slightly strong force. In order to use the seal seal 170, first, the transparent sheet 179 is peeled off from the mount 178. Then, the transparent sheet 179 peels from the mount 178 with the seal sticker 170 attached to the back side. After the seal seal 170 is attached to the main control board 60 together with the transparent sheet 179, when the transparent sheet 179 is pulled away from the main control board 60, only the transparent sheet 179 is peeled off, and the seal sticker 170 is controlled by the second adhesive layer 172. The substrate 60 is bonded. After that, in the same manner as in the above-described embodiment, the main control board 60 to which the seal seal 170 is bonded is attached to the flange portion 53 of the case lid 50, so that the first adhesive layer 171 has the flange portion of the seal seal 170. Adhere to 53. After that, when the main control board 60 is removed from the case lid 50, a trace of peeling off the seal seal 170 remains in substantially the same manner as in the above-described embodiment. Further, since the character string 174 overlaps the circumferential band 173b and the straight line portion 173c of the seal body 173, the character string 174 is also cut off.
