<P>PROBLEM TO BE SOLVED: To provide a game machine in which a transparent sheet of a game board can be uniformly processed to produce a plane emission. <P>SOLUTION: In the game board 30 having a game region into which game-playing balls are hit and including a plywood board 420 to which front surface side some nails for use in giving a variation to action of each of the flowing-down game-playing balls on the game playing region can be hit and fixed and a transparent resin plate 400 showing optical transparency overlapped at the front surface side of the plywood board 420 to cover at least the game playing region of the plywood board 420 the transparent resin plate 400 is provided with a through-hole 409 at a predetermined location in the game playing region and the inner wall of the through-hole 409 of the transparent resin plate 400 is provided with a light incident part 450 for giving incident light, so that light can be entered not only from the outer peripheral side surface of the transparent resin plate 400 (for example, the transparent thin plate) but also light can be entered at the inner wall of the through-hole 409 of the transparent resin plate 400, irregular brightness or darkness at the transparent resin plate 400 can be reduced and the transparent resin plate 400 can be uniformly applied with plane emission. <P>COPYRIGHT: (C)2013,JPO&INPIT |
