  Next, the detailed structure of the above-described substrate case 100 will be described with reference to FIGS. 4 to 7. A substrate case (a substrate case for a gaming machine) 100 according to the present embodiment is a rectangular box-shaped transparent top. A case (first case) 101, a rectangular box-shaped transparent lower case (second case) 102, an upper seal cover (first cover part) 103, and a lower seal cover (second cover part) 104 are provided. ing. A storage space is formed inside the upper case 101 and the lower case 102, and the main board 115 on which a RAM or the like is mounted is stored in the storage space.

  The upper case 101 and the lower case 102 are overlapped by slide fitting, and an upper seal mounting portion (first seal mounting portion) 105 is formed on the upper case 101, and a lower seal is formed on the lower case 102. A mounting portion (second seal mounting portion) 106 is formed. As shown in FIG. 7, after these two seal mounting portions 105 and 106 are overlapped and fixed together with a flat head screw (screw) 107, the seal seal 108 straddles both seal mounting portions 105 and 106. Can be pasted. This seal seal 108 is a known one having a rectangular base sheet with an adhesive layer formed on the back surface, and an IC tag 108a is embedded in the adhesive layer. The IC tag 108a includes a long antenna extending along the diagonal line of the base sheet, and an IC chip disposed near the center of the antenna, and the unique identification information stored in the IC chip is a reader. It can be read by the machine. Further, the base sheet of the seal seal 108 can be easily broken using fingers, and the IC tag 108a is simultaneously cut by breaking the base sheet.

  The upper seal mounting portion 105 is a plate-like structure that protrudes outward from the short side portion of the upper case 101, and a step 105 c that is lowered by one height by substantially the same height as the thickness of the seal seal 108 is formed on the surface thereof. Is formed. Further, the upper seal mounting portion 105 is provided with a through hole 105a for inserting a flat head screw 107 at a position slightly closer to one side from the center. The through hole 105a is processed (dish processing) in accordance with the inclination of the head of the countersunk screw 107. When the countersunk screw 107 is inserted into the through hole 105a, the head of the countersunk screw 107 is placed in the through hole 105a. The seal sticking surface of the upper seal mounting part 105 and the head of the countersunk screw 107 are substantially flush with each other. Therefore, even if the seal seal 108 is attached to the stepped portion 105c of the upper seal mounting portion 105 after the countersunk screw 107 is attached to the through hole 105a, the seal seal 108 is not raised by the head of the countersunk screw 107. . Further, the upper seal mounting portion 105 is provided with a pair of bottomed holes 105b. The bottomed hole 105b is for fitting a pair of protrusions 103b formed on the upper seal cover 103 described later.

  The lower seal mounting portion 106 is a plate-like structure that protrudes outward from the short side portion of the lower case 102. When the upper seal mounting portion 105 and the lower seal mounting portion 106 are overlapped with each other, A screw hole 106a in which a female screw is formed is provided at a position matching with 105a (see FIG. 6). Therefore, when the upper seal mounting portion 105 and the lower seal mounting portion 106 are overlapped, and the flat head screw 107 is inserted into the screw hole 106a from the through hole 105a and screwed, the upper seal mounting portion 105 and the lower seal mounting portion are attached. The part 106 is fixed integrally. Note that a step (not shown) having a height substantially equal to the thickness of the seal seal 108 is formed on the surface of the lower seal mounting portion 106 as well as the upper seal mounting portion 105. The lower seal mounting portion 106 is also provided with a pair of bottomed holes (not shown), similar to the upper seal mounting portion 105. This hole is for fitting a pair of protrusions 104b formed on the lower seal cover 104 described later.

  The upper seal cover 103 is a transparent resin molded product, has a rectangular box shape that can cover the upper seal mounting portion 105 at a time, and covers the upper seal mounting portion 105. Part of the box shape is open. Therefore, the upper seal cover 103 has a substantially L-shaped cut surface cut in a direction orthogonal to the longitudinal direction thereof. As shown in FIG. 7, an easy-to-removal portion 109 is provided on the top surface of the upper seal cover 103. The easy-to-removable portion 109 includes an opening 112 provided on the top surface of the upper seal cover 103, four legs 111 provided so as to stand up from the edge of the opening 112, and the four legs 111. It is comprised with the cover part 110 supported.

  Normally, since the lid portion 110 covers the opening 112, it is difficult to insert a tool such as a screwdriver into the opening 112. However, when the four leg portions 111 are cut using a nipper or the like, the lid portion 110 is removed. When removed, the opening 112 is exposed. The opening 112 is provided on the top surface of the upper seal cover 103 at a position facing the head of the countersunk screw 107. When the opening 112 is exposed, a screwdriver or the like is passed from the opening 112 to the head of the countersunk screw 107. It can be inserted toward.

  Further, a pair of protrusions 103 b for fitting into a pair of bottomed holes 105 b provided in the upper seal mounting portion 105 are provided on the back surface of the top surface of the upper seal cover 103. Therefore, when the protrusion 103b of the upper seal cover 103 is fitted into the bottomed hole 105b of the upper seal mounting portion 105, the upper seal cover 103 and the upper seal mounting portion 105 are positioned. Further, a welding line L1 is formed in a U shape along the periphery on the back surface of the top surface of the upper seal cover 103. Therefore, when the upper seal cover 103 is attached to the upper seal mounting portion 105 and ultrasonic vibration is applied, the weld line L1 is melted and the upper seal cover 103 and the upper seal mounting portion 105 are welded. The pair of protrusions 103b are located on the weld line L1.

  The lower seal cover 104 is a transparent resin molded product, has a rectangular box shape that can cover the lower seal mounting portion 106 at a time, and covers the lower seal mounting portion 106. Therefore, a part of the box shape is opened. Therefore, the lower seal cover 104 has a substantially L-shaped cut surface cut in a direction orthogonal to the longitudinal direction.

  Further, a pair of protrusions 104 b for fitting into a pair of bottomed holes (not shown) provided in the lower seal mounting portion 106 are provided on the back surface of the top surface of the lower seal cover 104. Therefore, when the protrusion 104b of the lower seal cover 104 is fitted into the bottomed hole of the lower seal mounting portion 106, the lower seal cover 104 and the lower seal mounting portion 106 are positioned. Further, a welding line L <b> 2 is formed in a U shape along the periphery on the back surface of the top surface of the lower seal cover 104. Therefore, when the lower seal cover 104 is attached to the lower seal mounting portion 106 and ultrasonic vibration is applied, the weld line L2 melts and the lower seal cover 104 and the lower seal mounting portion 106 are welded. The pair of protrusions 104b are located on the weld line L2.

  Next, a procedure until the main board 115 is housed and sealed in the board case 100 configured as described above will be described with reference to FIG. First, after fixing the main board 115 to the inside of the lower case 102 with screws, the upper case 101 is slid in the X direction, the upper case 101 is overlapped with the lower case 102, and the upper case 101 and the lower case 102 are fastened together. The upper seal mounting portion 105 and the lower seal mounting portion 106 are fixed using a flat head screw 107 as well as fixing the portion (not shown). Next, the seal seal 108 is affixed as a whole over the countersunk screw 107 so as to straddle the upper seal mounting portion 105 and the lower seal mounting portion 106.

  Then, the protrusion 103 b of the upper seal cover 103 is fitted into the bottomed hole 105 b of the upper seal mounting portion 105 to position the upper seal cover 103 and the upper seal mounting portion 105. Thereafter, ultrasonic vibration is applied to the upper seal cover 103 to weld the upper seal cover 103 and the upper seal mounting portion 105. Similarly, the protrusion 104b of the lower seal cover 104 is fitted into a bottomed hole (not shown) of the lower seal mounting portion 106 to position the lower seal cover 104 and the lower seal mounting portion 106, and thereafter Ultrasonic vibration is applied to the seal cover 104 to weld the lower seal cover 104 and the lower seal mounting portion 106 together.

  Thereby, the sealing of the substrate case 100 is completed. In this state, since the seal seal 108 is entirely covered by the upper seal cover 103 and the lower seal cover 104, the seal seal 108 cannot be peeled off. It should be noted that the identification information stored in the IC tag 108a of the seal seal 108 is obtained by the reader device by bringing the reader device closer to the upper seal cover 103 or the lower seal cover 104 with respect to the substrate case 100 in the sealed state. Can be read.

  When releasing the sealing of the substrate case 100, first, the four leg portions 111 of the easy-to-removable portion 109 are cut with a nipper or the like to expose the opening 112. Then, a screwdriver or the like is inserted into the opening 112, and the screwdriver or the like is forcedly abutted against the head of the countersunk screw 107 from above the sealing seal 108, and the countersunk screw 107 is removed. Since the seal seal 108 has a structure that is easily broken as described above, when the flat screw 107 is turned by forcibly pushing a screwdriver or the like against the counter screw 107, a part of the seal seal 108 is broken by the force. Therefore, the countersunk screw 107 can be removed even if the seal sticker 108 is stuck on the countersunk screw 107.

  Then, if the flat head screw 107 is removed, the upper seal mounting portion 105 and the lower seal mounting portion 106 are fixed, so that the upper case 101 is pulled out in the Y direction in FIG. 7 while grasping the lower case 102 by hand. With this force, the sealing seal 108 is shredded and the sealing between the upper case 101 and the lower case 102 is released, and the main board 115 can be inspected. At this time, it is not necessary to remove the seal covers 103 and 104. That is, the upper case 101 can be separated from the lower case 102 while the upper seal cover 103 is welded to the upper case 101 and the lower seal cover 104 is welded to the lower case 102.

  As described above, in the substrate case 100 according to this embodiment, the upper seal mounting portion 105 of the upper case 101 and the lower seal mounting portion 106 of the lower case 102 are overlapped and screwed, and in this state After the sealing seal 108 is pasted so as to straddle both the seal mounting portions 105 and 106, the seal covers 103 and 104 are welded to the both seal mounting portions 105 and 106, respectively. Since it is entirely covered by the seal covers 103 and 104, it is difficult to peel off the seal seal 108. Moreover, since the seal covers 103 and 104 are firmly fixed by welding, it is difficult to remove the seal covers 103 and 104. Therefore, according to the present embodiment, an illegal act such as peeling off the seal sticker 108 can be prevented.

  Moreover, in order to release the seal of the substrate case 100, the leg portion 111 of the excisable portion 109 must be cut. Therefore, if the trace of the leg portion 111 is seen, the substrate case 100 is surely sealed. You can discover that it has been lifted. Further, in order to release the sealing of the substrate case 100, it is necessary to remove the countersunk screw 107, but in order to remove the countersunk screw 107, the countersunk screw 107 must be loosened while tearing the sealing seal 108 with a screwdriver or the like. Therefore, the IC tag 108a is destroyed in the process of loosening the flat head screw 107. Further, even in the process of sliding the upper case 101 with respect to the lower case 102 in the Y direction, the seal seal 108 is torn off, so that the IC tag 108a is destroyed. Therefore, even if the reader device is brought closer, it becomes impossible to read the identification information stored in the IC tag 108a, thereby reliably detecting that an illegal act has been performed.

  In other words, when the substrate case 100 is illegally opened and the ROM or the like of the main substrate 115 is replaced, there is always a trace of the excisable portion 109 being cut, and the seal seal 108 is broken and the IC tag 108a is destroyed. To do. Therefore, according to this embodiment, it is possible to discover that the sealing of the substrate case 100 has been reliably released by both visual observation and a reader.

  In the above-described embodiment, the easy-to-removable portion is configured such that the lid portion 110 is supported by the leg portion 111 standing up from the opening 112. However, the lid portion 110 has a shape slightly smaller than the inner diameter of the opening 112, and the opening 112 It is good also as an easy excision part of the structure which hold | maintains the cover part 110 inside the opening 112 by the leg part 111 extended inward from. Further, instead of a configuration in which the leg portion 111 is cut with a nipper or the like, another structure, for example, a perforated or thin-walled easy-to-cut portion may be formed on the upper seal cover 103.

  In the above embodiment, the upper case 101 and the lower case 102 are configured to overlap with each other by sliding fitting. Instead of this configuration, the upper case 101 and the lower case 102 can be opened and closed via a hinge. It can also be configured.

  In the above embodiment, the substrate case 100 that houses the main substrate 104 has been described. In addition to the above, the above-described effect control processing unit 12a, special symbol display control unit 12b, lamp control processing unit 12c, payout It can also be used as a case for storing the control processing unit 12e and the control board of the firing control processing unit 13.
