For this reason, the lower back cover 90 and the left back cover 120 are connected to each other by a single operation of screwing the screws 125 into the game board 30, and both the lower back cover 90 and the left back cover 120 are connected to the game. It can be fixed to the board 30. This effect is the same for the right wrap portion 104 of the lower lining 90, the left wrap portion 142 of the upper lining 140, and the right wrap portion 143 of the upper lining 140.

  A boss 102, a boss 127, and a boss 151 that house the protruding portion of the rail nail 33 that fixes the outer rail 31 to the game board 30 are formed in the back wall 80, and the inner rail 34 is fixed to the game board 30. The boss portion 101, the boss portion 126, and the boss portion 136 in which the protruding portion of the nail 33 is accommodated are formed on the back wall 80, and each of the boss portion 102, the boss portion 127, and the boss portion 151 brings the outer rail 31 to the game board 30. The protruding portion of the rail nail 33 to be fixed is surrounded, and each of the boss portion 101, the boss portion 126, and the boss portion 136 is configured to surround the protruding portion of the rail nail 33 that fixes the inner rail 34 to the game board 30. Therefore, the operator can handle the game board 30 without paying attention to the protruding portion of the rail nail 33. Therefore, the rail nail 33 having a large length and the veneer made according to the veneer game board can be used. It is possible to fix the metal outer rail 31 and the metal inner rail 34 to the translucent game board 30 by using both of the rail press-fitting machines having a large press-fit amount according to the game board.

  By forming the lower left thickness adjusting unit 106, the lower right thickness adjusting unit 107, the upper left thickness adjusting unit 149, and the upper right thickness adjusting unit 150 on the back wall 80, the thickness dimensions of the four corners of the game board 30 are respectively set. The lower left thickness adjusting unit 106, the lower right thickness adjusting unit 107, the upper left thickness adjusting unit 149, and the upper right thickness adjusting unit 150 are each combined with the game board 30 and the support unit 5 and the stopper 6 of the inner frame 2. Sandwiched between. Therefore, a veneer game board having a thickness dimension in the front-rear direction larger than that of the translucent game board 30 can be sandwiched between the support portion 5 and the stopper 6 of the inner frame 2 from the front-rear direction. The inner frame 2 can be used in common between the translucent game board 30 and the veneer game board.

  The rib 91 is formed only on one surface of the lower lining 90, the rib 121 is formed only on one surface of the left lining 120, the rib 131 is formed only on one surface of the right lining 130, and the one surface of the upper lining 140 is formed. Since the rib 141 is formed only on one side and the one side of the back wall 80 is joined to the game board 30 so that the rib 91, the rib 121, the rib 131, and the rib 141 all face the rear surface of the game board 30, the back wall 80 The rear surface, which is the opposite surface, is smoothed. For this reason, when the game board 30 is transported to the manufacturing facility with the joining state of the back wall 80, the smooth rear surface of the back surface 80 can be transported by the transport roller, so that the game board 30 is affected by the presence of the back surface 80. It becomes possible to convey to a manufacturing facility with the stable attitude | position, without being done.

  Since the back wall 80 is joined to the rear surface of the game board 30, when the game board 30 is transported to the manufacturing facility, the rear surface of the game board 30 is rubbed and damaged by the transport rollers, or when the game board 30 is stacked and stored. The rear surface of the game board 30 is prevented from being rubbed and damaged by the outer rail 31 and the inner rail 34 of the game board 30 positioned below. For this reason, since the degree to which the game board 30 becomes defective in the manufacturing stage is reduced, the yield is improved.

In the first embodiment, the front surface of the lower back cover 90 and the front surface of the upper back cover 140 may be printed directly, or decoration may be applied by directly sticking a seal.
In the first embodiment, any one of the lower lining 90, the left lining 120, the right lining 130, and the upper lining 140 is molded separately from the remaining one, or Any two of the back cover 90, the left back cover 120, the right back cover 130, and the upper back cover 140 are formed separately from the rest, or the lower back cover 90 and the left back cover 140 Any three of 120, the right side hook 130 and the upper side hook 140 may be molded separately from the remaining ones.

In the first embodiment, decoration may be applied to the front surface of the left back cover 120 and the front surface of the right back cover 130.
In the first embodiment, the decorative symbol display 220 having a size other than 20 inches may be used.

  In the first embodiment, one, two, or three of the lower left thickness adjusting unit 106, the lower right thickness adjusting unit 107, the upper left thickness adjusting unit 149, and the upper right thickness adjusting unit 150 are attached to the game board 30. Moreover, you may clamp between the support part 5 and the stopper 6. FIG.

  In the first embodiment, a rib may be formed on the rear surface of both the left rear case 120 and the right rear case 130, and the front surface may be a smooth surface. Moreover, about both the lower back cover 90 and the upper back cover 140, a rib may be formed in a rear surface and a front surface may be made into a smooth surface. In order to obtain the effect of “stability during conveyance” described above, it is sufficient to form a rib on the front surface and make the rear surface smooth with respect to at least one back surface. As in the example or the other example of the latter, it is preferable to form ribs on the front surface of at least both of the back ridges at the opposing positions and to make the rear surface smooth.

In the said Example 1, you may use the decorative design indicator 220 which has a square-shaped liquid crystal screen.
In the first embodiment, the boss portion 101, the boss portion 102, the boss portion 126, the boss portion 127, the boss portion 136, and the boss portion 151 into which the protruding portion of the rail nail 33 is inserted may be formed in a bottomed shape. . In this case, since the tip of the rail nail 33 is covered with the bottom plate such as the boss portion 101, the operator need not pay attention to the tip of the rail nail 33 at all. In addition, since the rigidity of the back hook 80 is increased, the effect of suppressing distortion of the back hook 80 is enhanced.

  In the first embodiment, the boss portion 101, the boss portion 102, the boss portion 126, the boss portion 127, the boss portion 136, and the boss portion 151 into which the protruding portion of the rail nail 33 is inserted are formed in a prismatic shape such as a quadrangular prism shape. May be. In this case, it is advantageous for securing the rigidity of the back hook 80.
