<P>PROBLEM TO BE SOLVED: To provide a game ball lifting and polishing device which reduces noise in a game hall, contributes to energy conservation, and reduces management cost of the game ball by reducing power consumption as measures to take visitors back to the game hall, because recently the number of visitors to the game hall is decreasing, sales are remarkably declining in the game hall for a reason that the noise in the game hall is loud and uncomfortable. Ž<P>SOLUTION: The electromagnetic game ball lifting and polishing device successively executes an excitation attraction of soiled game balls 121 by an electromagnetic force, and lifts the game balls from a lower tank of a game machine installation island to an upper tank of the game machine installation island while polishing the game balls by bringing the game balls into contact with a polishing cloth extended on the opposite side of a lifting surface. Thus, a mechanical drive part is removed, and a motor and rotation belt that may cause noise are eliminated. Also, clearances are provided so that the game balls do not contact with each other during being polished, because collisions of the game balls also cause the noise.
