<p><P>PROBLEM TO BE SOLVED: To propose a method for controlling light irradiated from a light transmission body for improving an optical representation effect and to provide a pinball game machine and a slot machine with improved interests in games. <P>SOLUTION: Light beams different in color are supplied to both ends of the light transmission body, respectively, light intensity of a light source which supplies light from one end of the light transmission body is relatively changed compared with the light intensity of a light source which supplies light from the other end of the light transmission body, thereby changing an occupancy by the same color in the light transmission body, and control for changing over the colors of the light beams supplied to both ends of the light transmission body is made at the time when such occupancy has reached a prescribed occupancy to carry out a rotational optical presentation. <P>COPYRIGHT: (C)2004,JPO</p> |
