PROBLEM TO BE SOLVED: To provide a game machine which hardly interferes with smooth circulation of game balls, and can separate game balls having different diameters efficiently and accurately with a simple configuration.SOLUTION: A game machine comprises a separation mechanism (a classification unit 70) for separating game balls M1 into a large-diameter ball (a regular ball M11) and a small-diameter ball (an excessively small ball M12). The separation mechanism comprises: an opening part (a classification hole 726) having a dimension and a shape which restrict the passage of the large-diameter ball and do not restrict the passage of the small-diameter ball; push-back means (a lower rotary vane 727) for pushing back the large-diameter ball, whose passage is restricted by the opening part, to the opposite side from a direction in which the large-diameter ball attempts to pass through the opening part; and delivery means (an upper rotary vane 725) for delivering the large-diameter ball pushed back by the push-back means to a predetermined discharge route (a large-diameter ball discharge passage 724D, a large-diameter discharge port 726M).SELECTED DRAWING: Figure 33 |
