  In the second modification, as shown in FIGS. 14A and 14B, the warp route constituting member 80 has a connecting portion 82 on the right side of the electric decoration substrate cover 52 (the opening side of the liquid crystal display viewing window). It is formed as a single piece. Accordingly, the front surface 27b of the opening side flat plate portion 27 of the back base 20 is in front of the front surface 25a of the outer peripheral side flat plate portion 25 (which coincides with the back surface 10a of the game board 10 at the time of assembly). To the front surface 52a of the electric decoration board cover 52 is formed as the bottom of a recess that is retracted by a distance obtained by subtracting the thickness t of the opening-side flat plate portion 27 from the distance.

  According to the second modified example, the warp route constituting member 80 is an integrally molded product with the electric circuit board cover 52, and the opening-side flat plate portion 27 of the back base 20 is warped with respect to the outer peripheral side flat plate portion 25. Since it is formed as the bottom of the recess that is retreated by a distance obtained by subtracting the thickness t of the opening-side flat plate portion 27 from the distance from the front surface 80a of the member 80 to the front surface 52a of the illumination board cover 52, positioning in the mounting operation is possible. In addition to being naturally implemented, a reinforcing effect is also achieved by connecting the opening edge of the liquid crystal display viewing window 22 of the back base 20 and the opening edge of the center window 11 of the game board 10. Since the warp root component itself is located in the liquid crystal display viewing window 22 of the back base 20, the rear end 80b is located behind the back base 20 as shown in FIG. It may be configured as a component to be integrated, and may be configured as an integral component that directly contacts the side surface of the electrical decoration board case 52 without using the connecting portion 82.

  As shown in FIG. 15, the third modification is that the warp root component member 80 is not integrally molded, but is screwed to the right side of the electric decoration board cover 52 (the opening side of the liquid crystal display viewing window), and the back base 20 opening side flat plate part 27 is the distance which reduced the thickness of opening side flat plate part 27 from the distance from the front surface of warp route constituent member 80 to the front surface of electric decoration board cover 52 to perimeter side flat plate part 25. It is formed as the bottom of the recessed portion that has been retracted.

  In the third modification, positioning in the mounting operation can be naturally performed, and a reinforcing effect by connecting the edge of the opening of the back base 20 and the game board 10 is exhibited.

  As described above, according to the present embodiment, including the modified example, the structure of the game board 10 is complicated or the strength is reduced by utilizing the visual effect of the game board 10 made of a light-transmitting material. Without any problem, it is possible to secure a wide game area and perform an effect by the illumination device. Further, it is possible to facilitate the alignment of the warp route component 80 attached to the back side of the game board 10 in order to utilize a visual effect and secure a wide game area, and at the same time, the liquid crystal display of the back base 20 The edge of the device viewing window 22 and / or the center window 11 of the game board 10 can be reinforced. Furthermore, the large-sized liquid crystal display device 30 for taking advantage of the visual effect can be easily attached and detached, and the holding can be ensured without the edges being seen, and the back base 20 having a large opening can be reinforced. .

  Although one embodiment as the best mode for carrying out the invention has been described above, the present invention is not limited to this, and various modifications can be made without departing from the scope of the invention.

  For example, the warp root structure 80 is not limited to a groove type having a U-shaped cross section, and may be configured as a cylindrical type part.

  Further, the retreat distance of the recesses 28a to 28c of the back base 20 is the same as the height of the highest part of the lens bodies 61 to 63 in the front-rear direction, so that the lens bodies 61 to 63 extend in the height direction from the game board 10 and the back base 20. You may comprise so that it may fit in between. In this case, in addition to the effect that the fixing of the lens bodies 61 to 63 is stabilized, the liquid crystal display viewing window 22 on the back base 20 is connected in the same manner as when the back base 20 and the game board 10 described in the first to third modifications are connected. In addition, the effect of bringing the opening edge of the center window 11 of the game board 10 closer to the state of being firmly reinforced like the fixed end instead of the free end is also exhibited.
