<p><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/convex shape. A parallel surface 41 of the outer lens member 40 facing a parallel surface 32 of the inner lens member 30 is flat for total reflection, and recesses in an optically design curved surface shape are scattered on a surface 42 on the side opposite the parallel surface 41. On the surface 42 of the outer lens member 40, a convex lens part 44 disposed corresponding to the position of the LED 25 on the substrate 24 is formed. <P>COPYRIGHT: (C)2012,JPO&INPIT</p> |
