PROBLEM TO BE SOLVED: To impart sufficient interest by utilizing a game area on a game board as a performance area.SOLUTION: A cell part includes a laminated light guide 7701 that is disposed while facing a game area at the rear of the game area and allows light guide plates made of a synthetic resin having light transmission properties with the front face as a light guide emission surface to be overlapped in a plurality of layers in a longitudinal direction. In each light guide plate, respective background patterns 7750-7756 expressed by scattering of light are recorded, the respective background patterns 7750-7756 express a common character, recording positions of the background patterns in the respective light guide plate are set to be mutually the same position, and pattern postures are made different mutually. A control part switches and lights up light sources corresponding to the respective light guide plates among a plurality of layers, and a plurality of types of respective background patterns having mutually different postures are switched and expressed at fixed positions, thus three-dimensional displaying the background patterns of the game area within a thickness range of lamination. |
