A hook (not shown) is formed which engages with a jagged protrusion 82 formed on the plate to prevent movement in the extraction direction.

  The case lid 50 is a member corresponding to the substrate case constituting body of the present invention, and is formed by molding a transparent polycarbonate resin as shown in FIGS. 2 and 3. A pair of lid long wall portions 52, 52 erected along each long side of the lid bottom surface portion 51 are provided. 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 walls 52, 52 are formed with flanges 53, 53 (only one side is shown in FIGS. 2 and 3) to be fitted into the rail grooves 43, 43 of the case body 40 and to slide. ing. One of the flanges 53 is provided with a plurality of connector windows 54 for exposing the connector 64 of the main control board 60. Further, a seal bonding portion to which a seal seal 70 is bonded is provided on the peripheral surface of the connector window 54 of the collar portion 53, and a plurality of convex portions 53a extending in the vertical direction are formed at the seal bonding portion. In addition, the surface of the convex part 53a is roughened so that adhesiveness may improve. 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. 2). 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. In addition, the portion of the printed wiring board 61 of the main control board 60 to which the seal seal 70 is bonded is roughened so as to improve the adhesiveness. 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 paid out. Each electronic component is fixed to the back side of the mounting surface of the main control board 60 with solder.

  As shown in FIG. 4, the seal seal 70 is connected to an external IC tag scanner 90 (see FIG. 6) via a foil-like antenna 72 formed in a multiple spiral shape made of metal foil (for example, copper foil, aluminum foil, etc.). An IC tag 71 having an IC chip 73 (wireless communication unit of the present invention) that performs wireless communication with the IC tag 71, and a first adhesive layer 76 formed on the surface of the IC tag 71 on which the foil antenna 72 is provided, The IC tag 71 includes a second adhesive layer 77 formed on the surface where the foil antenna 72 is not provided. As shown in FIG. 5, the seal seal 70 has a first adhesive layer 76 adhered to the surfaces of a plurality of convex portions 53a provided on the flange portion 53 of the case lid 50, and a second adhesive layer 77 being a main control. The substrate 60 is adhered to the mounting surface side. Of the foil-like antenna 72, an area bonded to the surface of the convex portion 53a via the first adhesive layer 76 is an adhesive region 72a (strong adhesion region), and faces between the convex portion 53a and the convex portion 53a. The non-adhering area 72b (weakly adhering area) is the area that is attached.

  Further, as shown in FIG. 6, the IC chip 73 of the IC tag 71 that constitutes the seal sticker 70 has a memory 75 having a capacity of several bytes to several kilobytes, and performs reading / writing with respect to the memory 75 as well as various types. And a processing execution unit 74 that executes arithmetic operations. When the IC tag scanner 90 is operated by the operator and the reader / writer unit 92 passes a current through the coiled antenna 91, a magnetic field is generated in the antenna 91, and the magnetic field passes through the foil antenna 72 of the IC tag 71. Then, current flows through the foil antenna 72 by electromagnetic induction, and the IC chip 73 is activated by this current. Thus, the IC tag 71 of this embodiment employs a so-called electromagnetic induction method. Subsequently, the process execution unit 74 reads unique identification data (for example, a serial number) stored in advance in the memory 75 and transmits this identification data to the IC tag scanner 90 via the foil antenna 72. When the IC tag scanner 90 receives the identification data from the IC tag 71 via the antenna 91, the IC tag scanner 90 determines whether or not the received identification data matches the identification data previously allocated to the main control board case 30. If they match, the fact that they are normal is notified, and if they do not match (including the case where identification data cannot be received from the IC tag 71 even after a predetermined time), there is a possibility that an illegal act has been made. Notify that there is.

  Next, a method for assembling the main control board case 30 will be described. FIG. 7 is a perspective view showing how the seal seal 70 is adhered. First, the first adhesive layer 76 formed on the surface of the seal seal 70 on which the foil-like antenna 72 is provided is pressed against the surfaces of the plurality of convex portions 53a provided on the flange portion 53 of the case lid 0. Thus, the seal seal 70 is adhered to the case lid 50. 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 printed wiring board 61 of the main control board 60 is bonded to the second adhesive layer 77 of the seal seal 70. As a result, as shown in FIG. 5, the surface of the sealing seal 70 on which the foil antenna 72 is provided is bonded to the convex portion 53a of the case lid 50 via the first adhesive layer 76, and the foil antenna The entire surface where 72 is not provided is bonded to the main control board 60 via the second adhesive layer 77. In addition, the surface of the foil-shaped antenna 72 that faces the convex portion 53a is bonded through the first adhesive layer 76 to become a bonded area 72a, and the surface that does not face the convex portion 53a is a non-bonded area 72b. Become. Thereafter, as shown in FIG. 3, the case lid 50 to which the main control board 60 is fixed is slid along the rail grooves 43, 43 of the case main body 40 to be integrated. As a result, as shown in FIG. 2, 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.

  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 sealing by the sealing seal 70 is illegally released, that is, when the case lid 50 and the main control board 60 are illegally separated, of the foil-shaped antenna 72 constituting the IC tag 71 of the sealing seal 70, the case lid 50 A shearing force acts between the bonding area 72a bonded to the convex portion 53a and the non-bonding area 72b not bonded to the case lid 50. Then, as shown in FIGS. 8 and 9, the foil-shaped antenna 72 formed to be very thin is cut by this shearing force, and the non-bonded area 72 b of the foil-shaped antenna 72 remains on the sealing seal 70. The area 72a remains on the convex portion 53a of the case lid 50. As a result, the IC chip 73 of the IC tag 71 cannot receive current or transmit / receive data via the foil antenna 72. For this reason, even if the inspector operates the IC tag scanner 90 to acquire the identification data from the IC tag 71, the identification data is not responded from the IC tag 71. Therefore, the IC tag scanner 90 has been cheated. It will be notified that there is a possibility. The inspecting person can easily know whether or not the main control board case 30 has been cheated by this notification content.

  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, and the lid bottom 51 corresponds to the constituent bottom.

  According to the present embodiment described in detail above, the case lid 50 and the main control board 60 are separated if an attempt is made to act illegally on the main control board 60. In this case, the case cover 50 is provided on the seal seal 70. Since the foil-shaped antenna 72 is cut, the IC chip 73 of the IC tag 71 cannot perform wireless communication with the IC tag scanner 90. Therefore, the person in charge of the inspection performs an illegal act on the main control board 60 of the pachinko machine 20 by inspecting whether or not wireless communication is impossible between the IC tag scanner 90 and the IC tag 71 provided on the seal seal 70. It can be easily determined later.

  Further, when the case lid 50 and the main control board 60 are separated from each other, the vicinity of the connection portion P (see the circle in FIG. 2) between the foil antenna 72 and the IC chip 73 is cut. It is possible to reliably prevent the IC chip 73 from performing wireless communication with the IC tag scanner 90 via the rectangular antenna 72, and it is possible to accurately determine whether an illegal act has been performed.

  Further, the foil-like antenna 72 is formed in a multiple spiral shape, and when the case lid 50 and the main control board 60 are separated, a plurality of locations are cut for each spiral of the foil-like antenna 72. For this reason, even if there is something that is not cut among the multiple spirals of the foil-like antenna 72 for some reason when the case lid 50 and the main control board 60 are separated from each other, it is very possible that all the spirals are not cut. small. Therefore, it is possible to reliably prevent the IC chip 73 from performing wireless communication with the IC tag scanner 90.

  Furthermore, since the IC chip 73 of the IC tag 71 wirelessly communicates a response signal including unique identification data to the calling signal from the IC tag scanner 90, even if the seal seal 70 having the IC tag 71 is forged. If the identification data included in the response signal to the IC tag scanner 90 is incorrect, it can be easily found that the forgery has been made.

  The foil-like antenna 72 has a simple configuration in which it has a bonding area 72a (strong bonding area) bonded to the convex portion 53a of the case lid 50 and a non-bonding area 72b (weak bonding area) not bonded. When the lid 50 and the main control board 60 are separated from each other, it is possible to obtain an operational effect that the lid 50 is cut into a large number. That is, when the case lid 50 and the main control board 60 are separated from each other, a shearing force is generated between the two areas 72a and 72b of the foil antenna 72, so that the foil antenna 72 is easily cut.

  Further, when the foil antenna 72 is cut, the IC chip 73 of the IC tag 71 not only becomes unable to wirelessly communicate but also no current is supplied, so that illegal acts can be detected more reliably.

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

  Still further, the case lid 50 is roughened because the bonding surface of the case lid 50 to which the sealing seal 70 is bonded and the surface of the convex portion 53a of the main control board 60 to which the sealing seal 70 is bonded are roughened. Since the adhesive force between the seal seal 70 and the main control board 60 and the seal seal 70 is increased, it is more difficult to perform illegal acts such as replacement of the main control board 60.

  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 effects as the above-described embodiment can be obtained.

  In the above-described embodiment, the convex portion 53a has a shape extending in the vertical direction so as to traverse the multiple spirals of the foil-like antenna 72. However, the shape is not particularly limited, and for example, as shown in FIG. Alternatively, the convex portion 53a may be formed in a shape extending in the left-right direction so as to traverse the multiple spirals of the foil antenna 72. Even in this case, the same effect as the above-described embodiment can be obtained. Or although not shown in figure, the convex part 53a may be made into the shape extended in the diagonal direction, and may be arranged along an antenna line as a polygonal shape or a substantially circular shape.

  Furthermore, in the above-described embodiment, an area bonded to the convex portion 53a of the case lid 50 in the foil antenna 72 is defined as an adhesive area 72a (strongly bonded area), and an area not bonded to the convex portion 53a is defined. Although the non-adhering area 72b (weakly adhering area) is used, the first adhesive layer 76 has the same shape as the convex part 53a instead of forming the convex part 53a on the case lid 50 as shown in FIG. You may form so that it may become. In this way, the portion of the foil antenna 72 where the first adhesive layer 76 exists becomes the bonded area 72a, and the portion where the first adhesive layer 76 does not exist becomes the non-bonded area 72b. Also in this case, when the case lid 50 and the main control board 60 are pulled apart, a shearing force acts between the two areas 72a and 72b, so that the foil antenna 72 is cut as shown in FIG. Therefore, substantially the same effect as the above-described embodiment can be obtained.

  Alternatively, as shown in FIG. 12A, the first adhesive layer 76 made of an adhesive having a strong adhesive force is formed in the same shape as the convex portion 53a instead of forming the convex portion 53a on the case lid 50. The auxiliary adhesive layer 78 made of an adhesive having a weak adhesive force may be formed at other locations. In this way, the portion of the foil antenna 72 where the first adhesive layer 76 exists becomes the strong adhesion region 72a, and the portion where the auxiliary adhesive layer 78 exists becomes the weak adhesion region 72b. Also in this case, when the case lid 50 and the main control board 60 are pulled apart, a shearing force acts between the two areas 72a and 72b, so that the foil antenna 72 is cut as shown in FIG. Therefore, substantially the same effect as the above-described embodiment can be obtained.

  Furthermore, in the embodiment described above, an electromagnetic induction type is adopted as the IC tag 71, but a microwave type may be adopted. In the microwave method, the foil-like antenna 72 receives a radio wave from the IC tag scanner 90 and supplies a current generated by resonance to the IC chip 73. Also in this case, when the foil antenna 772 is cut, the IC chip 73 not only becomes unable to perform wireless communication, but also no current is supplied.

  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 above-described embodiment, the pachinko machine 20 has been described as an example. However, the gaming machine to which the present invention can be applied is not limited to a pachinko machine. For example, a slot machine, a pachinko machine and a slot machine are used. Of course, it can also be applied to a fused game machine.
