Thus, or by mixing a light diffusing agent into the synthetic resin material, the light diffusing treatment is performed, so that the outer guide rail 4 can emit light uniformly over the entire surface.
[0044]
In other words, taking into account the decorativeness, it is possible to decorate the guide rail itself with electrical decoration, etc., and the degree of freedom of decoration of the guide rail is increased, and it can also have the function of frame decoration. As in the embodiment, this is particularly suitable for the case where the outer guide rail 4 is configured as the outer guide rail 4 that defines the outer wall of the launch ball guide path 5. In this embodiment, since the synthetic resin outer guide rail 4 is integrally formed with the synthetic resin frame ornament 24 provided around the synthetic resin outer guide rail 4, the frame ornament 24 is attached to the game board together with the outer guide rail 4. It can be easily attached and detached, and the range of design is dramatically expanded.
[0045]
In the above-described embodiment, a pachinko machine, which is a typical ball game machine, has been described as an example. However, the ball game machine according to the present invention includes a pinball machine, an arrange ball game machine, and a sparrow ball. It can also be applied to a ball game machine such as a game machine.
