The lid 4 can be opened and closed in a single-opening manner with the connection portion as a fulcrum.

  A control board 6 is accommodated in the case body 2. The control board 6 includes a printed wiring board 7 and electronic components 8 such as a CPU, a ROM, and a RAM disposed on the upper surface thereof, and game control contents such as a big hit probability are written in the ROM. Further, the bottom plate 9 of the case body 2 is opened substantially on the entire surface, leaving the periphery, and the opening 10 is shielded by the transparent plate 11. Each of the transparent plates 11 is fixed together with the control substrate 6 which is fitted at the four corners of the fixing projections 12 formed at the four corners of the peripheral edge of the bottom plate 9 and is superposed on the upper portion. A screw is fixed to the projection 12. Thus, the control board 6 is protected and the soldered back surface 7 ′ of the printed wiring board 7 constituting the control board 6 can be seen from the bottom surface side of the case body 2. Further, the case body 2 is formed of a conductive synthetic resin containing carbon, and can prevent the electrostatic charge and protect the control board 6.

  On the other hand, the lid 4 is formed of a transparent synthetic resin so that the electronic component 8 of the control board 6 accommodated in the case body 2 can be seen from above. Further, a transparent plate 13 having a conductive net surface 13 ′ on the lower surface is laminated on the back surface of the lid body 4, and the control substrate 6 can be protected from static electricity by the conductive net surface 13 ′. ing. The lid body 4 has a longitudinal width substantially equal to the longitudinal width of the case body 2, a lateral width smaller than the lateral width of the case body 2, and the opposing edges of the hinge portions 5 b and 5 b facing downward. A side plate portion 4 ′ is formed by bending in an L shape. As a result, when the lid 4 is closed, as shown in FIGS. 7 and 8, a gap 14 is formed between the side plate portion of the case body 2 facing the side plate portion 4 ′, and the control is performed. Various connectors (not shown) for connecting the substrate 6 to an external circuit can be arranged in the gap 14 on the control substrate 6.

  A plurality of boss portions 16 a to 16 d each provided with a mounting hole 15 are arranged at predetermined intervals along the lateral width direction on two side edges opposed in the longitudinal direction of the case body 2. In this embodiment, the case where four boss portions 16a to 16d are respectively provided on the two side edges of the case body 2 is illustrated, but the number is not limited thereto. Further, the boss portions 16 a to 16 d are disposed at symmetrical positions on the two side edges of the case body 2.

  On the two side edges of the lid 4 corresponding to the two side edges of the case body 2 provided with the boss parts 16a to 16d, a plurality of flange parts 17a to 17d are paired with the boss parts 16a to 16d. Each is arranged. As shown in an enlarged view in FIG. 4, each of the flange portions 17 a to 17 d includes a pair of rib pieces 18 and 18 that protrude laterally from the side edge of the lid body 4 at a predetermined interval, and both rib pieces 18 and 18. The engagement piece 19 is supported by both side edges, and a screw insertion hole 20 is formed in the engagement piece 19.

  Then, as shown in FIG. 5, a fastening screw 21, which will be described later, is inserted into the insertion hole 20 from above, and the head portion 22 of the fastening screw 21 is locked to the locking piece 19. A male screw can be screwed into the mounting hole 15 of each of the boss portions 16a to 16d. Accordingly, the flange portions 17a to 17d and the boss portions 16a to 16d forming a pair can be individually fastened.

  The fastening screw 21 is a so-called one-way screw provided with an operation head 22 that can be screwed only in the tightening direction, and a male screw is formed on the body 23. As shown in FIG. Of the pair of ridges located on both sides of the driver engagement groove 22a formed on the operation head 22 in a simple screw, the ridge is provided with ridges 22b with which the driver abuts during screwing operation in the tightening direction. This is a special screw that is removed from the crest where the driver abuts during operation, and once tightened in the mounting hole 15, it cannot be screwed in the loosening direction and cannot be removed. For this reason, it is generally expected to be very difficult to obtain.

  Accordingly, the boss portions 16a to 16d are each formed with a storage portion 25 having an inlet / outlet 24 through which a spare screw 21 'can be inserted and removed from the surface facing the flange portions 17a to 17d. 21 'is stored one by one. As shown in FIG. 5, the entrance / exit 24 of each storage part 25 is closed by the flange parts 17a-17d at the time of sealing so that the stored spare screw 21 'can be prevented from falling off. Yes. 5 shows two screws, that is, a fastening screw 21 and a spare screw 21 ′. However, when the pair of boss portions 16a to 16d and the flange portions 17a to 17d are fastened by the fastening screw 21, they are stored. Since the spare screw 21 ′ housed in the portion 25 cannot be taken out, any one screw appears in actual use.

Next, the method of use and operation will be described.
In order to seal the control board storage case 1, with the lid 4 closed, a fastening screw 21 made of a one-way screw is inserted into the insertion hole 20 of the locking piece 19 from above the flange portion 17a. The male screw of the body portion 23 is screwed into a tightening shape by screwing it into the mounting hole 15 of the boss portion 16a paired with the flange portion 17a through a screwing operation in the tightening direction. Thereby, the flange part 17a and the boss | hub part 16a are fastened, the closed state of the cover body 4 is hold | maintained, and the control board storage case 1 is sealed.

  Here, by simultaneously fastening the pair of flange portions 17a and 17a and the boss portions 16a and 16a disposed at positions symmetrical to each other on the two side edges of the control board storage case 1, the control board storage case 1 Fastening is performed at two opposing positions, and the sealing can be made more reliable. In addition, you may make it stick the conventional sealing sticker further to the boundary part of the case main body 2 and the cover body 4 of the control board storage case 1 sealed in this way.

  Since the fastening screw 21 cannot be screwed in the loosening direction once tightened, the control board storage case 1 cannot be opened by removing the fastening screw 21. For this reason, when the control substrate storage case 1 is unavoidably opened by inspection or the like, the sealed portion must be destroyed. The sealing portion can be easily broken by cutting the rib pieces 18, 18 of the flange portion 17 a with an appropriate tool such as a nipper and separating the locking piece 19 together with the fastening screw 21 from the lid 4. Then, the separated locking piece 19 remains on the boss portion 16a while being fastened by the fastening screw 21, leaving a trace of opening.

  Sealing again can be performed by fastening the other flange 17b and boss 16b with the fastening screw 21 in the same manner as described above. Further, the re-opening can be performed by cutting the rib pieces 18 and 18 of the flange portion 17b with an appropriate tool such as a nipper in the same manner as described above. By sequentially repeating this operation, sealing and unsealing can be performed a predetermined number of times corresponding to the number of the boss portions 16a to 16d and the flange portions 17a to 17d forming a pair.

  In addition, for the second and subsequent seals, a spare screw 21 ′ as a fastening screw 21 housed in each housing part 25 of the boss parts 16 b to 16 d is used. In this way, by storing the spare screw 21 'in the storage portion 25 of the boss portions 16b to 16d, it is possible to always ensure a spare for the fastening screw 21 that is an indefinite use time and is a special screw. Can do. When the control board storage case 1 is sealed, each spare screw 21 ′ is closed off by the flange portions 17 b to 17 d at the entrance / exit 24 of each storage portion 25. For example, the entrance / exit 24 is opened at the same time, and the spare screw 21 ′ in the vicinity of the place of use can be easily visually recognized, and can be immediately taken out from the opened entrance / exit 24 and used.

  In the above embodiment, the pair of boss portions 16a to 16d and the flange portions 17a to 17d are arranged on the two side edges facing each other in the longitudinal direction of the control board storage case 1 so as to face the seal once. However, the sealing method is not limited to this, and the boss portions 16a to 16d on one side edge are not limited to this, but the two boss portions 16a to 16d and the flange portions 17a to 17d are fastened. The flanges 17a to 17d can be sealed even if only one pair is fastened per seal. Moreover, it is also possible to perform sealing by arranging a pair of boss portions 16a to 16d and flange portions 17a to 17d on one side edge facing the pivoting portion pivotally pivoting the lid 4. is there.

  Moreover, in the said Example, although the boss | hub parts 16a-16d are provided in the case main body 2 side, and the flange parts 17a-17d are provided in the cover body 4 side, it is also possible to reverse the arrangement position.

  Here, in the present invention, since the storage portion 25 of the spare screw 21 ′ is not necessary for the boss portion 16a used for the initial fastening, the storage portion 25 is replaced with the boss portions 16b to 16b other than the boss portion 16a. Only 16d is formed.

  Further, the storage portion 25 of the spare screw 21 ′ can be disposed anywhere in the control board storage case 1 except for the boss portions 16 a to 16 d, but in this case, when the control board storage case 1 is opened. It is desirable that only the spare screw 21 'can be taken out. For this reason, as shown in FIG. 9, the structure which provides the accommodating part 25 in the inner wall face of the side-plate part of the case main body 2, and closes the entrance / exit 24 of the spare screw 21 'with the cover body 4 may be proposed. As a result, the entrance / exit 24 is sealed by the lid 4 at the time of sealing, so that the spare screw 21 ′ stored in the storage section 25 is prevented from dropping or lost. On the other hand, if the lid 4 is opened at the time of opening, the spare screw 21 'can be taken out. The storage section 25 may store a spare screw 21 'and a related seal member used for sealing a preliminary seal of a conventional seal seal and an inspection sheet.

  On the other hand, the fastening screw 21 made of a one-way screw is easier to remove the driver's tip from the driver engagement groove 22a of the operation head 22 during screwing operation in the tightening direction, as compared with a general screw. 10 and 11 show other configurations of the boss portions 16a to 16d and the flange portions 17a to 17d that can cope with this, and each locking piece 19 of the flange portions 17a to 17d includes A guide hole 20 ′ having a predetermined depth that is substantially equal to the outer diameter of the operating head 22 of the fastening screw 21 and that can guide the operating head 22 in the screwing direction is formed in the upper portion of the insertion hole 20. In addition, a support hole portion 15 ′ into which a body portion 23 of a fastening screw 21 through which the insertion hole 20 is inserted is fitted in a substantially close fitting manner at the upper portion of each attachment hole 15 of the boss portions 16 a to 16 d. Is formed. The depth of the support hole 15 ′ is set to a depth at which the operation head 22 of the fastening screw 21 is inserted into the guide hole 20 ′ in a state where the body 23 of the fastening screw 21 is fitted. .

  In this configuration, when the pair of boss portions 16a to 16d and the flange portions 17a to 17d are sequentially fastened by the fastening screw 21, as shown in FIG. 10, the support hole portions 15 'of the boss portions 16a to 16d are provided. The body 23 of the fastening screw 21 through which the insertion holes 20 of the flange portions 17a to 17d are inserted is fitted in a substantially tight fit, so that the fastening screw 21 does not swing, and the upper portion of the mounting hole 15 is not swung. Positioned at an appropriate position and held in a temporarily fixed state. In addition, the fastening screw 21 in the temporarily fixed state in this way has a screwdriver at a point in time when the screwing operation is started because the operation head portion 22 is immersed in the guide hole portion 20 ′ of the flange portions 17a to 17d. The tip of the driver engaged with the engaging groove 22a is positioned in the guide hole 20 ′, and the tip of the driver is not detached from the operation head 22 by the guide hole 20 ′.

  In this state, by performing a screwing operation in the tightening direction, the operating head 22 is guided in the screwing direction by the guide hole 20 ′, and is inserted into the support hole 15 ′ and positioned. As shown in FIG. 11, the body portion 23 of 21 can be easily screwed into the attachment hole 15 following the support hole portion 15 ′.
