PROBLEM TO BE SOLVED: To efficiently remove dirt of game balls in a game machine where game balls are circulated to be used. SOLUTION: The Pachinko machine 1 has an outer frame 2 and a front frame 3 in front of the outer frame, and a glass door frame 4 is mounted to be opened/closed on the front side of the front frame. An upper tray 5 for reserving game balls is mounted under the glass door frame 4, and a game board 8 is detachably mounted on the rear side of the front frame 3. The Pachinko machine 1 is structured so that game balls are circulated. A relatively small number of game balls are repeatedly shot and the shot balls flow down repeatedly in a game area. All the game balls guided to the rear side of the game board 8 are guided to the upper tray 5 through a ball receiving gutter in a rear side guide part on the rear side of the front frame 3. The game balls passing through the ball receiving gutter are cleaned by a long cleaning means disposed along the ball receiving gutter. COPYRIGHT: (C)2004,JPO
