The operation of the winning ball processing mechanism 120 configured as above will be explained with reference to FIG. 5. Note that although Figure 5 shows the mechanism on the near side, that is, the mechanism by which 7 prize balls are paid out, the mechanism on the back side, that is, the mechanism by which 13 prize balls are paid out, is also the same. , the explanation thereof will be omitted.

First, the state of the prize ball dispensing device 70 is such that the superstructure stopper 74b is opened, a predetermined number (7) of prize balls are stored in the prize ball storage cylinder 73c, and the stopper part 98c of the substructure stopper 96b is in the state where the prize balls are stored. The state in which it has entered the cylinder 73c is maintained. In such a state, the winning balls flowing down the second winning ball detector 44b and guided to the winning ball guide path 121b are placed on winning soil while rotating the stopper member 123b counterclockwise as shown in the figure. It is placed on the section 122b. Then, the rotating cam 137b that is constantly rotating
contacts the rotating roller 135b of the extrusion member 132b and rotates the extrusion member 132b so as to push it forward. As the extrusion member 132b rotates, the winning soil placement section 122b
The upper winning ball moves in the extrusion direction, but at this time, the winning ball moves while being held between the pressing surface portion 134b of the pushing member 132b and the winning ball contacting surface portion 130b of the rotating member 127b. Also, at this time, since the engagement portion 125b of the stopper member 123b and the engagement convex portion 129b of the rotating member 127b are disengaged, the rotating member 127b rotates in the counterclockwise direction shown in the figure. do. As the rotating member 127b rotates, the front end of the engaging convex portion 129b rotates the stopper member 123b clockwise, and the abutting portion 126b enters so as to close the end of the winning ball guide path 121b. At the same time, the interlocking rod 113b rises to rotate the operating member 109b upward. Then, the vertical sliding member 87b rises, so that the upper work stopper 74
The contact piece 80 of b comes into contact with the lower part of the contact recess 92b of the control protrusion 90b, and the stopper part 7 of the superstructure stopper 74b
9 enters the entrance of the prize ball storage cylinder 73c and locks the prize balls so that they do not flow into the prize ball storage cylinder 73C. Further, since the contact convex portion 89b of the vertical sliding member 87b and the contact roller 100b of the substructure stopper 96b are disengaged, the substructure stopper 96b becomes free, and therefore the prize ball in the prize ball storage tube 73c The stopper part 98c is pressed and rotated by the earth pressure, and a predetermined number of prize balls stored in the prize ball storage cylinder 73c are discharged into the prize ball discharge passage 55.

When a predetermined number of prize balls are paid out as described above, the winning balls held between the rotating member 127b and the pushing member 132b are removed by further rotation of the pushing member 132b, so that the winning balls are removed from the winning soil placing portion 122b. Winning ball discharge passage 140
Fall to b. Then, the rotating member 127b rotates clockwise and returns to its original state, so the interlocking rod 113b and the vertical sliding member 87b descend to fix the substructure stopper 96b again, and the upper part The operator opens the stopper 74b and introduces the prize ball into the prize ball storage cylinder 73c.

Moreover, at this time, the stopper member 123b also
Since the rotation of 27a returns to the original state, the next winning ball waiting at the end of the winning ball discharge path 121b is allowed to flow down, is driven to the winning ball placement part 122b, and the above-mentioned operation is repeated. .

In addition, the winning balls discharged to the winning ball discharging passage 140b,
The detection switch 143b and the winning ball detector 145b are activated, and the balls flow from the winning payout port 146 to the ball extraction passage 54 and are discharged to the outside of the pachinko game machine 1.

This ensures smooth vertical movement without uneven wear over a long period of time. In addition, even if some dust or the like adheres to the bottom, since the contact area between the sliding plates 88a, 88b and the prize ball storage cylinder main body 71 is small, the vertical movement thereof will not be hindered. In addition, the guide groove portions 83a, 83
Since the inner lower part of b is formed with a gap between the stoppers 86a and 86b, the vertical sliding members 87a and 8
