FIG. 7 is a cross-sectional view taken along the line for explaining the operation of the first fixing means and the second fixing means. FIG. 7 is a one-way mounting screw used in the first fixing means and the second fixing means. 99 and 102 are plan views and side views, FIG. 8 is a plan view and side view of the fracture mounting screw 103 having the same function as the one-way mounting screw, and FIG. FIG. 10 is a side view showing the storage structure of the pre-sealing seal 101, and FIG. 11 is a cross-sectional view taken along line BB in FIG.

  Thus, the board storage box 60 is constructed by assembling and constructing a box body 61 that houses and supports the game control circuit board 110 and a cover body 80 that closes the upper surface of the box body 61. The board storage box 60 can be detachably attached to a mounting base 120 fixed to a mounting boss (not shown) protruding from the back surface of the mechanism plate 41. Hereinafter, each assembly component of the substrate storage box 60 will be described.

  First, the box body 61 is formed of a synthetic resin (or metal) in a rectangular parallelepiped shape whose upper surface is open, and a large number of heat radiation holes 62 for radiating heat generated inside are formed in almost the entire side wall. Yes. A relatively large rectangular bottom surface opening 63 is formed on the bottom surface of the box body 61, and an L-shape that engages with an engagement rail 121, which will be described later, of the mounting base 120 at the longitudinal opening edge of the opening 63. An engagement piece 64 is formed to hang down.

  Further, a locking hole 73 is formed in the center of the front portion of the bottom surface of the box body 61, and support positioning protrusions 65 protrude from the left and right sides of the one side long side, and stop protrusions 66 extend from the left and right sides of the other side long side. And a re-occlusion mounting boss 68 is provided in the vicinity of the support positioning protrusion 65. The locking hole 73 engages with a locking protrusion 124 formed on the mounting base 120 when the board storage box 60 is mounted on the mounting base 120 to support and fix the entire substrate storage box 60 to the back surface of the mechanism plate 41. Is. The support positioning protrusions 65 support both sides of one long side of the game control circuit board 110 with a presser member 87 (described later) provided on the cover body 80, and the stop protrusions 66 support the game control circuit. Both ends of the other long side portion of the substrate 110 are fixedly supported with screws 117. The support positioning protrusion 65 and the stop protrusion 66 will be described in detail later. The re-occlusion mounting boss 68 is provided with a fastening hole 69. When the cover body 80 is re-occluded as will be described later, the mounting hole 93 is formed in the recess 92 of the cover body 80. The spare one-way mounting screw 100 is screwed to match.

  Engagement holes 70 are formed at two locations on the side wall in the longitudinal direction of the box 61 and at one location on both side walls in the short side direction. The engagement hole 70 is adapted to engage with a locking hanging piece 84 formed on the back surface of the cover body 80 when the cover body 80 is covered with the box body 61. In the normal state, the engagement state with the locking drooping piece 84 can be released from the outside by operating from the outside, but in this embodiment, the short side of the box 61 A one-way mounting screw 99 is screwed into the fixing hole 75 of the mounting protrusion 74 projecting outward on the side wall and the mounting hole 90 of the mounting portion 88 projecting outward on the short side of the cover body 80. I wear it. For this reason, since the one-way mounting screw 99 cannot be rotated in the loosening direction, the box body 61 and the cover body 80 cannot be separated. If they are to be separated, the cutting connecting rib 91 that connects the attachment portion 88 of the cover body 80 to the cover body 80 must be destroyed as will be described later. By checking whether or not the 91 portion is broken, it can be easily understood whether or not the box body 61 and the cover body 80 are separated. The configuration and operation of the mounting protrusion 74 and the mounting portion 88 will be described in detail later.

  Furthermore, seal seals 98 and 101 for securing the covering state are affixed to each one of the side wall in the longitudinal direction and the both side walls in the short side direction of the box body 61. An anti-peeling wall 71 protrudes so as to form a recess along the outer shape of the seal seal 98. However, the seal seal 101 attached to the peeling prevention wall 71 formed on the side wall in the longitudinal direction is a preliminary seal sticker 101 attached after re-occlusion. Further, the side wall on the other side in the longitudinal direction of the box body 61 is a wiring lead-out recess 72 formed with a low height, and a plurality of elliptical shapes are formed on both sides of the bottom surface opening 63 of the box body 61. The opening 67 is opened. Since the opening 67 is blocked by the transparent plate 76 described below, the opening 67 does not have a function as a heat radiating hole, but contributes to reduction of raw materials forming the box body 61.

  Further, a transparent plate 76 is provided in contact with the bottom surface from the inside of the box body 61 in order to close the bottom surface opening 63 of the box body 61. Therefore, interval holding cylinder portions 77 are formed on the upper surface at the four corners of the transparent plate 76, and the support positioning projections 65 and the stop projections 66 are passed through the interval holding cylinder portions 77 and held at predetermined positions. The lower surface of the game control circuit board 110 abuts on the upper surface of the interval holding cylinder portion 77 to hold the distance between the transparent plate 76 and the game control circuit board 110. Thus, by closing the bottom surface of the box 61 with the transparent plate 76, the back surface (solder surface) of the game control circuit board 110 can be seen through from the outside. If you do a tampering work that connects or mount electronic components), you will immediately know. In this sense, it is sufficient that the size of the bottom opening 63 closed by the transparent plate 76 is large enough to see the entire solder surface while the substrate storage box 60 is tilted. The transparent plate 76 is provided with a support protrusion 78 at the center of the longitudinal edge, so that the game control circuit board 110 is not deformed by an upward force applied when connecting the wiring to the connector 113 described later. Further, the back surface of the game control circuit board 110 is supported. Further, the transparent plate 76 is provided with a through hole 79 for allowing the re-occlusion mounting boss 68 to pass therethrough.

  On the other hand, the cover body 80 that closes the upper surface of the box body 61 is formed integrally with a transparent synthetic resin, and a partition piece 81 whose other side portion in the longitudinal direction is bent downward, It has become. As shown in FIG. 1, when the cover body 80 is attached to the box body 61, the partition piece 81 is positioned such that the connector mounting area 114 of the game control circuit board 110 appears outside to form the connection opening 82. It is bent at the position. Thereby, the wiring from the outside can be connected to the connector 113 facing the connection opening 82 in a state where the cover body 80 is assembled to the box body 61. In addition, on the surface of the cover body 80, a large number of heat radiation holes 83 (range surrounded by a two-dot chain line in FIG. 1) for releasing the heat generated inside to the outside are formed.

  Furthermore, a latching portion 85 that engages with the upper edge of the side wall of the box body 61 is provided on the long side direction edge and the short side direction edge of the cover body 80 at an appropriate interval. The cover body 80 is formed with a locking hanging piece 84 that hangs downward. A claw portion is formed at the distal end of the locking drooping piece 84, and this claw portion is adapted to engage with the engagement hole 70 of the box body 61.

  In addition, presser members 87 are suspended from both sides of one side of the cover body 80, and the cover body 80 is attached to the box body 61 between the upper surface of the cover body 80 and the side wall of the box body 61. A seal seal 98 is affixed so as to pass. Further, a peeling prevention wall 86 is provided so as to project a concave portion along the outer shape of the seal seal 98 at a place where the seal seal 98 is affixed to the cover body 80.

  Before describing the holding member 87 in detail, the structure of the game control circuit board 110 will be briefly described. The game control circuit board 110 is configured by a printed circuit board as is well known, and the upper surface of the game control circuit board 110 is the ROM 111. The mounting surface of the electronic component is included, most of the mounting surface is used as the electronic component mounting region 112, and the rear part is the connector mounting region 114 on which the connector 113 is mounted. The game control circuit board 110 has locking holes 115 corresponding to the support positioning projections 65 on the left and right sides of one side, and locking holes 116 corresponding to the locking projections 66 on the left and right sides of the other side. A through hole 118 that is formed and penetrates the reclosing attachment boss 68 is also formed.

  The operation of the pressing member 87 of the cover body 80 configured as described above will be described below. In the box 61 with the transparent plate 76 mounted, the locking hole 115 on one long side of the game control circuit board 110 is inserted into the tip protruding portion of the support positioning protrusion 65, and the stop hole 116 on the other long side is inserted. Place on the stop projection 66. In this state, the hole 117 of the stop hole 116 and the hole of the stop protrusion 66 are made to coincide with each other and the screw 117 is screwed, whereby the game control circuit board 110 is temporarily fixed to the box body 61. Thereafter, the cover body 80 is mounted from above the box body 61. At this time, the tip of the presser member 87 abuts on the upper surface of the game control circuit board 110, and the tip projection of the support positioning projection 65 penetrating the locking hole 115 is formed in the center of the presser member 87. Since one side long side portion of the game control circuit board 110 is clamped and fixed by the support positioning projection 65 and the pressing member 87, the other side long side portion is completely fixed by the screw 117. The game control circuit board 110 is fixed in the board storage box 60.

  After the game control circuit board 110 is fixed to the box body 61 and covered with the cover body 80 as described above, the structure cannot be separated unless the box body 61 and the cover body 80 are broken. A mounting portion 88 is integrally formed on the front side via a pair of cutting connecting ribs 91. The mounting portion 88 is formed with a concave portion 89 whose bottom surface is closed, and a mounting hole 90 is formed in the center of the bottom surface of the concave portion 89, and the mounting hole 90 corresponds to the fixing hole 75 of the mounting protrusion 74. ing. On the other hand, a concave portion 92 whose bottom surface is closed is formed slightly inside the cover body 80 at a position corresponding to the mounting portion 88, and a mounting hole 93 is formed in the center of the bottom surface of the concave portion 92. It corresponds to the fastening hole 69 of the re-occlusion mounting boss 68. Among the above-described configurations, the fixing hole 75 of the mounting protrusion 74 of the box body 61 and the mounting hole 90 of the mounting portion 88 of the cover body 80 are formed in the initial stage as described above. The one-way mounting screw 99 for holding the closed state is fixed, and the fixing hole 69 of the reclosing mounting boss 68 of the box 61 and the mounting hole 93 of the recess 92 are reclosed (recovered). ), The spare one-way mounting screw 100 for holding the closed state of the cover body 80 and the box body 61 is fastened.

  Thus, the spare one-way mounting screw 100 used at the time of re-occlusion is attached to the spare screw mounting portion 95 integrally formed on the inner surface of the spare screw storage plate 94 suspended from the cover body 80 at the symmetrical position of the partition piece 81. It is designed to be detachably stored and supported. As shown in FIGS. 9 and 11, the spare screw mounting portion 95 is formed in a C-shaped cross section so as to sandwich the spare one-way mounting screw 100. Two spare screw mounting portions 95 are formed so as to correspond to the left and right reclosing mounting bosses 68. On the other hand, on the inner side surface of the partition piece 81, there are protrusions 96, 97 for storing the pre-sealing seal 101 attached to the peeling prevention walls 71, 86 formed in the longitudinal direction of the box body 61 and the cover body 80 at the time of re-closing. It is integrally formed.
