PROBLEM TO BE SOLVED: To provide a game machine which can excellently polish game balls to use by circulating them in the game machine.SOLUTION: A game machine is configured such that almost columnar polishing members 353, 354 are disposed on both sides of an S-shaped polishing part 360 of a polishing passage 362 and the two polishing members 353, 354 rotate in the direction in which they move game balls downstream. Further, a passage width of the polishing part 360 is made one size smaller than a diameter of a game ball, the length of a straight line connecting a center of the first polishing member 353 and a center of the second polishing member 354 is set shorter than a sum of a radius of the first polishing member 353, the diameter of the game ball, and a radius of the second polishing member 354. Moreover, a rotational speed of the second polishing member 354 is set faster than a rotational speed of the first polishing member 353, so that game balls rotate while being polished.SELECTED DRAWING: Figure 28 |
