PURPOSE:To maintain a normal display even when a game ball goes onto the ball rolling face of a variable display device. CONSTITUTION:In the ball rolling face 32 of an ornamental member of an opening part on which a liquid crystal display board 34 is provided, the front part and an adjacent area of the liquid crystal display board 34 are set as a plating area 32A and a non-plating area 32B, respectively. Width (d) of the non-plating area 32B is taken large enough, and when simultaneously a game ball P comes into contact with a cover 33 on the liquid crystal display board 34 and the ball rolling face 32, the game ball P comes into contact with the non-plating area 32B. Since a unit base 26 is non-conductive, it does not occur than the part of the liquid crystal display board 34 and the ball rolling face 32 conduct through the game ball P. |
