The partition walls 69, 69 or the side walls 68a in the transparent display 20 are adjacent to each other. Therefore, each partition wall 69,6
In 9, the irradiation light from the irradiation lamps 79, 79 of the lighting fixture 78 in the unit U adjacent thereto is transmitted to the side, so that the entire area of the see-through portion 23 is uniformly and brightly illuminated. The effect can be expected to be improved. In each of the side wall portions 68a and 68b, a large number of convex portions 70 are provided so that light is diffused.
The illumination light from the illumination lamps 79, 79 of the lighting fixture 78 in the left and right symbol display units U, U is radiated outward while being diffused from the corresponding side wall portions 68a, 68b, and is a visible display portion plated. It can be expected that the illumination effect will be further improved by being reflected on the inner wall 67. Since each of the side walls 68a and 68b and each of the partition walls 69 and 69 are formed so as not to be transparent, the inside of each symbol display unit U is transparent through the transparent portion 23 from the front side of the pachinko machine P. Not done.

In the design variable display device K of the embodiment, each display window 24 in the see-through portion 23 is formed in a lens shape (FIG. 16 (a)), while the display area 24a is formed transparent and other than this. Since the non-display area 24b is formed opaque, the symbol S stopped on the pay line is clearly enlarged and displayed, and the stopped symbol S is displayed in an unclear manner other than on the pay line (FIG. 16 (b)). . Thereby, for example, when the big hit symbols are aligned on the winning line, a high-grade symbol display of "big hit" is displayed together with the lighting effect by the lighting fixture 78. Further, even if the jackpot symbols are arranged in a line other than the winning line, the player does not mistakenly recognize this as a "jackpot".

On the other hand, in the symbol variable display device K according to the embodiment, the display control board 44 of the display control device M for electrically controlling each symbol display unit U is divided into two, and the upper surface of the housing box 21 is separated. A large-sized component is mounted as an electronic component on the first substrate portion 46 located on the opposite side, and a small-sized component is mounted on the second substrate portion 47 located on the rear surface side of the housing box 21. Thereby, the thickness dimension in the front-rear direction of the portion of the display control device M facing the rear surface side of the housing box 21 can be reduced, and the pachinko machine P equipped with the symbol variable display device K is installed on an island in a game store. At this time, the amount of protrusion to the rear side can be reduced. That is, even if the symbol drum 33 of the symbol display unit U is increased in size by the thickness of the display control device M, the symbol variable display devices K, K facing each other in the island do not interfere with each other. Therefore, a powerful design can be displayed by increasing the size of the design drum 33, and the interest of the whole game can be enhanced, and the whole pachinko machine can be upgraded.

Further, in the display control device M, since a heavy component is mounted on the first substrate portion 46 facing the upper surface side of the housing box 21, the display control device M is mounted on the housing box 21 (metal frame 22). ) Is excellent in stability when mounted, and can be securely and stably fixed with one screw as in the embodiment.

7 is separated from the CPU 50 and the IC 51 mounted thereon, so that the influence of heat and noise on the CPU 50 and the IC 51 can be reduced. Moreover, since a large number of heat radiating holes 55d and 59a are formed in the upper portion of the board case 45, heat generated from the large components provided in the upper portion efficiently escapes to the outside and does not stay in the case. .

The position of the connectors 52 and 53 provided on the second board portion 47 is determined by the connection ports 52a and 53a.
Since the opening is set so as to open in the direction along the arrangement surface of the board portion 47 (the arrangement surface of the control board), the front and rear thickness of the portion of the display control device M facing the rear surface side of the housing box 21 is also set. Can be reduced. In addition, the connector 35 of each symbol display unit U faces the lower rear part of the housing box 21 and the corresponding connector 52 of the display control device M is disposed below the second substrate part 47, so that both connectors 3
The harness 36 connecting the 5, 52 can be shortened. That is, the material cost can be reduced, and the influence of noise due to the longer harness 36 can be suppressed.

In the design variable display device K of the embodiment, the connector 52 provided on the second substrate portion 47 is configured to face downward and is protected by the second case body 55. It is possible to prevent a pachinko ball falling on the rear side of the pachinko machine P in the installed island from colliding with the connector 52 and causing breakage or short circuit. Further, since the harness 36 is connected to the connector 52 from below, the harness 36 does not protrude rearward from the surface on which the second substrate portion 47 is provided, and the pachinko ball collides with the harness 36. Can also be prevented.
