<P>PROBLEM TO BE SOLVED: To provide a game machine that prevents reduction in brightness of a Yakumono (accessory) in a light performance state even when the number of light sources included in the Yakumono is reduced. <P>SOLUTION: Extension parts 22 and 23 of a movable Yakumono include a substrate 24 with an LED 25 mounted thereon, and an inner lens member 30 and an outer lens member 40 disposed close to the substrate 24. The inner lens member 30 has, on the side of the substrate 24, an inclined surface 31 which is inclined to the direction of light of the LED 25 on the substrate 24 and has an optically designed concave and convex shape. On a parallel surface 32 on the side opposite the inclined surface 31, a plurality of parts having an optically designed curved surface shape are provided. A parallel surface 41 of the outer lens member 40 facing the parallel surface 32 of the inner lens member 30 is flat for total reflection, and recesses having the optically designed curved surface shape are scattered on a surface 42 on the side opposite the parallel surface 41. <P>COPYRIGHT: (C)2012,JPO&INPIT |
