PROBLEM TO BE SOLVED: To provide a game machine capable of suppressing erroneous detection by light while illuminating operation means with the light and having variety in performance.SOLUTION: In a middle stop button 12 (a left stop button 11 and a right stop button 13 are as well) of a game machine 1 according to the present invention, a stop button operation part 81b that accepts an operation by a player is configured to have transmissivity in which light can be transmitted. A light source that emits light towards the stop button operation part 81b is arranged on a rear face side of the stop button operation part 81b. The game machine 1 is constituted of an optical sensor 78b as a switch that detects that an operation to the stop button 12 is performed by the player. Further, the game machine 1 is provided with a cylindrical member 74b as a defining member that defines an illumination region 90 of the light emitted from the light source and a shielding region 91 that shields the light. The optical sensor 78b is arranged in the shielding region 91.SELECTED DRAWING: Figure 11 |
