PROBLEM TO BE SOLVED: To provide a luminous performance device for a game machine, which can execute an optical performance in a highly variable luminescence mode without utilizing any slip-ring system.SOLUTION: A luminous performance device for a game machine comprises: a base portion 2 fixing a light source 1; a sun gear 3 arranged on the surface of the base portion 2; a planetary gear 4 meshing with the sun gear 3; a connection member 5 connecting the sun gear 3 and the planetary gear 4; and drive means 6 for driving the connection member 5 to revolve the planetary gear 4 while rotating the same. An optical display portion is formed in said planetary gear, and a through hole 10 extending through a rotation center axis portion 9 of the sun gear 3 is formed in the base portion 2. The connection member 5 is arranged through the through hole 10, and an optical path 11 for guiding the light from the light source 1 into said optical display portion is formed in the connection member 5. |
