PROBLEM TO BE SOLVED: To execute various types of light performances in a limited space by changing over light sources between surface-emitting light sources and point-emitting light sources according to the types of performances.SOLUTION: A drum performance unit 200 includes a single-unit light source group (a plurality of LED light sources 210) operated by a single control signal. Though being used for just controlling the lighting and lights-out, the LED light sources 210 can properly use light from the LED light sources 210 for the surface light-emission and point light-emission in response to operation of a louver member 240. This configuration dispenses with a space for separately disposing light sources for the respective functions, and, for example, the drum performance unit 200 according to the present embodiment can be assembled in a limited space on the back side of a game board 18. Further the LED light sources 210 are used for both of the surface light-emission and point light-emission so as to reduce the number of components.SELECTED DRAWING: Figure 6 |
