<P>PROBLEM TO BE SOLVED: To provide a pinball game machine in which decoration by light can be given to the outer surface of an outer transparent plate in a glass door structure in which two transparent plates are held by a holding frame. <P>SOLUTION: Two transparent plates of the glass door are constituted of an inner transparent plate 71 of which the outer peripheral side is held by the holding frame 65 and an outer transparent plate 72 which is arranged with a prescribed interval apart from the inner transparent plate to the layer's side and is made of a resin plate the outer peripheral side of which is held by the holding frame. A light decoration area 74 is formed by providing a light refraction part 72a in a prescribed area in the outer transparent plate. A light source 50 is arranged at a position corresponding to the prescribed area of the outer transparent plate. A part of the light emitted from the light source 50 is emitted to the player's side from the light decoration area 74 through the light refraction part 72a. <P>COPYRIGHT: (C)2012,JPO&INPIT |
