<P>PROBLEM TO BE SOLVED: To impart sufficient amusement by practically using a game area of a game board as a performance area. <P>SOLUTION: A cell part includes a layered light guide body 7701 disposed in the rear of the game area in a state that the layered light guide body 7701 is made to face the game area, and formed by overlapping a plurality of light guide plates made of synthetic resin having transmittance whose front faces are set as light guide emission faces in a layer state in the back-and-forth direction. Respective background patterns 7720a-7720c appearing by scattering of light are recorded in the respective light guide plates. Each background pattern represents a common character 7720, and is set as a pattern such that a shape of each recorded pattern is gradually magnified from the light guide plate positioned in the backmost position to the light guide plate positioned in the forefront. A peripheral control part sequentially turns on light sources from the light source corresponding to the light guide plate 7704 positioned in the backmost position to the light source corresponding to the light guide plate 7702 positioned in the forefront. The respective background patterns of the respective light guide plates are sequentially made to appear, so that the background pattern of the game area is three-dimensionally displayed. <P>COPYRIGHT: (C)2012,JPO&INPIT |
