PROBLEM TO BE SOLVED: To avoid the situations in which discharge current flows into an operation board to break down the operation board and the discharge current flows into a main control board or the like, thereby inducing malfunction to give a player put out balls illegally, by making difficulty in an entry of a foreign object into a gap between a case and a stop button.SOLUTION: An operation unit 100 in a game machine includes a button 42 for pressing down and a housing 113 in which the button 42 is movably stored. A space interposed between the button 42 and the housing 113 forms a communication path 170 which communicates an outside space where a button head 120 is exposed, with an inside space where an operation board 150 is arranged. The communication path 170 has a return part 171 which is turned back toward the outside space in the middle from the outside space to the inside space. |
