<p>PROBLEM TO BE SOLVED: To provide a ball polishing device for game machines, of a type incorporated in each game machine capable of exerting an excellent cleaning function at high processing power.SOLUTION: A ball polishing device 1 for game balls includes: a ball storage part 20 disposed inside a game machine and storing Pachinko balls 100; a sprocket-like ball feed rotary body 3A that is disposed at a bottom face side of the ball storage part 20 so as to horizontally rotate by drive of a motor 6, and conveys the Pachinko balls 100 while holding them in an outer peripheral-side recess part 30a; and a cleaning member 50A for removing contamination of the Pachinko balls 100. The ball polishing device, while circumferentially conveying the Pachinko balls 100 by the ball feed rotary body 3A, brings the Pachinko balls into slide contact with the cleaning member 50A and causes the cleaning member 50A to clean the Pachinko balls. An upper face central part of the ball feed rotary body 3A is protruded to form a downslope surface heading from the central side toward the outer peripheral side, and the cleaning member 50A is disposed down below the ball feed rotary body 3A to constitute a cleaning surface along the conveyance path of the Pachinko balls 100.</p> |
