A connector 105 is mounted.

  Next, how to attach and remove the control board unit 10 will be described. First, the sealing and fixing member 65 is fixed to the right end portion of the second base member 60 with the screw 42, and the first base member 50 is temporarily fixed to the back surface of the second base member 60. The first base member 50 and the second base member 60 are fixed to the rear plate 2D of the housing 2.

  Subsequently, the left end portion of the substrate case 20 containing the main control substrate 10 is engaged with the engagement piece 603 of the second base member 60, and the upper and lower edges are also engaged with the upper and lower engagement pieces 605b. In this state, the sealing member 66 is inserted into the sealing portion 222, the tip thereof is engaged with the sealing hole 652 of the sealing fixing member 65, and the sealing portion 222 is connected to the sealing fixing portion 65 of the sealing fixing member 65. It fixes to 653. Thereby, the substrate case 20 is fixed to the front surfaces of the second base member 60 and the sealing fixing member 65. After the substrate case 20 is fixed to the second base member 60 and the sealing fixing member 65, a sealing seal 67 is attached to the sealing seal attaching portion 654 of the sealing fixing member 65 in order to seal the substrate case 20 and the substrate base 40. And the second case member 22 adjacent thereto.

  Before the substrate case 20 is fixed to the second base member 60 and the sealing fixing member 65, the first case member 21 and the second case member 22 in the substrate case 20 are sealed by the sealing portion 221 and the fixing portion 212. Since the fixing members 66 are fixed to each other and sealed, it is practically impossible to open the substrate case 20 unless the sealing portion 221 is cut.

  In a state where the substrate case 20 is fixed to the rear plate 2D of the housing 2 via the second base member 60, the sealing fixing member 65, and the first base member 50, the sealing portion 222 is held by the sealing member 66. Since it is fixed to the sealing fixing portion 653 of the sealing fixing member 65, it is substantially impossible to remove the substrate case 20 from the rear plate 2D of the housing 2 unless the sealed sealing portion 222 is cut. Impossible. Moreover, since the periphery of each sealing part 221,222 is surrounded by the protective wall 651 of the sealing fixing member 65, each sealing part 221,222 is deform | transformed using an unauthorized tool etc., and sealing member Unauthorized actions such as removing 66 from the sealing portions 221 and 222 can be prevented.

  Furthermore, since the head of the screw 42 that fixed the sealing fixing member 65 to the second base member 60 is concealed by the substrate case 20, separating the sealing fixing member 65 from the second base member 60 Unless the substrate case 20 is removed from the second base member 60, it is substantially impossible. Thereby, it is possible to reliably prevent the sealing and fixing member 65 from being separated from the second base member 60 due to fraud.

  When the main control board 10 attached to the housing 2 is inspected, the sealing portion 222 sealed by the sealing member 66 is cut with a tool such as a nipper and separated from the second case member 22. At the same time, the engagement of the engagement pieces 603 and 605b engaged with the substrate case 20 is released and the sealing seal 67 is peeled off, whereby the substrate case 20 can be removed from the substrate base 40.

  After removing the substrate case 20 from the substrate base 40, by cutting the sealing portion 221 sealed by the sealing member 66, the substrate case 20 can be opened and the main control substrate 10 can be taken out.

  Further, when the game content of the gaming machine 1 is changed by replacing the main control board 10 or the like, the board case 20 is removed from the board base 40 by the same operation procedure as described above, and the main control board 10 is replaced with a new one. Replace with. The substrate case 20 is also replaced with a new one because the sealing portions 221 and 222 are cut and cannot be reused.

  In this case, conventionally, even if the substrate case 20 is detached from the substrate base 40, the substrate base 40 is reused as it is because the cut portion 222 and the sealing member 66 are attached to the substrate base 40. Since it is not possible, it is necessary to replace the entire substrate base 40 with a new one. However, in the embodiment of the present invention, since the sealing fixing member 65 to which the sealing portion 222 is attached can be separated from the second base member 60 fixed to the housing 2 by removing the screw 42, the sealing is performed. The first base member 50 and the second base member 60 fixed to the housing 2 can be reused while being attached to the housing 2 simply by replacing only the fixing member 65 with a new one. Further, since the seal seal 67 is attached to the second case member 22 and the seal seal attaching portion 654 of the sealing fixing member 65, the second base member 60 has a trace of the seal sticker 67 attached. The second base member 60 can be reused in its original form without remaining. Furthermore, since it is not necessary to remove the first base member 50 and the second base member 60 from the rear plate 2D of the housing 2, screws for fastening the first base member 50 and the second base member 60 to the rear plate 2D. Since the screw hole of the rear plate 2D with which 41 engages does not become an idiot hole, there is no need to repair the screw hole of the rear plate 2D.

Although the embodiment of the present invention has been described above, the following various modifications and changes can be made to the present embodiment without departing from the gist of the present invention.
(I) The first base member 50 in the substrate base 40 is made of synthetic resin, or the second base member 60 is made of metal, and the first base member 50 and the second base member 60 are integrally formed, The sealing fixing member 65 is detachably fixed to the integrally formed base member.
