PROBLEM TO BE SOLVED: To prevent a circulation device for game balls from becoming large even when a game ball polishing device is provided, and at the same time, to prevent ball clogging and failures from occurring in an enclosed ball type game machine which circulate-uses the game balls in such a manner that the game balls being launched from a launching device are retrieved, and the retrieved game balls are fed again to the launching device by a ball feeding device. SOLUTION: This enclosed ball type game machine is equipped with the ball polishing device 260 which is provided on the upstream side of the ball feeding device 240, and polishes game balls at a specified area of a standing-by flow passage 211 in which game balls to be fed wait. Thus, the circulation device (enclosed ball circulation device 200) which circulates game balls is miniaturized. Also, the ball polishing member 274 for polishing game balls is provided movably in the opposite direction from the contact direction of game balls. At the same time, an urging member 275 is provided which urges the ball polishing member 274 in the contact direction of game balls, and troubles such as ball clogging by the generation of bridging or a failure of the ball feeding device 240 are prevented from occurring. The ball polishing member 274 is urged to the game ball side to increase wiping-off effect. COPYRIGHT: (C)2008,JPO&INPIT
