  As described above, when the main board assembly 30 is swung backward by swinging the mounting shafts 57a and 57b with respect to the left and right bearing portions 15n and 16n, the work space is moved to the rear side of the image control board assembly 40. Can be formed. Therefore, even if the main board assembly 30 is attached so as to cover the image control board assembly 40 from the rear, the image control board assembly 40 can be attached to and detached from the game board 10 using this work space. Work becomes easy. In particular, since the image control board assembly 40 and the image display device 23 may require replacement and maintenance work, the main control board assembly 30 can be easily swung in this manner, thereby improving the efficiency of these work. Can be achieved.

  By the way, as shown in FIG. 11 and the like, in the game board 10, between the left and right main board mounting portions 15 and 16, for example, a connector for sending a power source or a signal to the image control board assembly 40 is provided. Therefore, it is necessary to attach and detach the metal plate 17 in a state where the main board assembly 30 is swung backward with respect to the left and right main board attaching portions 15 and 16.

  At this time, the left and right metal plate mounting portions 15c and 16c are formed to have smaller vertical and front-rear widths than the left and right support portions 15b and 16b provided with the left and right bearing portions 15n and 16n, and the left and right bearing portions. Since 15n and 16n are provided at the lower ends of the left and right support portions 15b and 16b, a gap 18 is formed between the lower end portion on the rear side of the metal plate mounting portions 15c and 16c and the lower end portion on the front side of the main board assembly 30. It is formed. Therefore, by using this gap 18, the metal plate 17 can be attached and detached even if the main board assembly 30 is attached to the left and right main board attachment portions 15 and 16 while being swung forward. it can. That is, when the metal plate 17 is attached to the left and right metal plate attachment portions 15c, 16c, since the end of the lower side surface portion 17c of the metal plate 17 is in the gap 18, this lower side surface portion 17c is connected to the left and right metal plate attachment portions 15c. , 16c so as to be in contact with the left and right lower side surface portions 15g, 16g, and finally, the metal plate 17 can be fixed by pushing the lower side surface portion 17c downward by the left and right lower projection portions 15m, 16m. The same applies when removing.

  In addition, since the case main body member 50 and the case lid member 60 constituting the main board assembly 30 are formed of a transparent material, the state of the main control board 31 mounted inside can be visually recognized from the outside. When a resin material such as ABS resin or PC is used, the shielding effect cannot be expected. For example, the main control board 31 is affected by noise from the image control board assembly 40 located on the front side. However, as described above, since the conductive metal plate 17 is attached between the left and right main substrate attachment portions 15 and 16 and the main substrate assembly 30, the metal plate 17 serves as a shield and prevents the main control substrate 31 from being connected. Noise can be reduced.

  In the embodiment of the present invention described above, the main effects achieved can be summarized as follows.

  First, by attaching the metal plate 17 between the left and right main board attachment parts 15 and 16, the strength of the left and right main board attachment parts 15 and 16 can be increased.

  Second, when the metal plate 17 is attached to the left and right main board attachment portions 15 and 16 by providing the left and right lower projections 15m and 16m on the left and right lower side surface portions 15g and 16g of the left and right metal plate attachment portions 15c and 16c. When the left and right mounting surface portions 15e, 16e of the left and right main board mounting portions 15, 16 and the mounting surface portion 17a of the metal plate 17 are in contact with each other, the lower side surface portion 17c of the metal plate 17 is pushed downward by the left and right lower protrusions 15m16m. Thus, the left and right engaging protrusions 15j and 16j and the left and right engaging portions 17f and 17g of the left and right engaging holes 17d and 17e are fitted, so that the metal plate 17 is attached to the left and right main board attaching portions 15 and 16. Can be fixed with a simple operation.

  Thirdly, when the main board assembly 30 is swung around the left and right bearing parts 15n and 16n of the left and right main board mounting parts 15 and 16, the lower end of the main board assembly 30 and the left and right metal parts By forming a gap 18 between the lower ends of the plate mounting portions 15c and 16c, the metal plate 17 is moved relative to the left and right main substrate mounting portions 15 and 16 in a state where the main substrate assembly 30 is swung. Can be attached and detached.

  Fourth, when the metal plate 17 positioned between the left and right main board attachment portions 15 and 16 and the main board assembly 30 is used as a shield, noise to the main board assembly 30 can be reduced.
