The lowest replenishing ball x in the ball passage 12 is held by the first stopper surface 28 and the second stopper surface 34, and the ball-to-ball contact area is Match the locking pawl entrance/exit hole 24.

When a safe ball occurs in a pachinko machine and flows out to the back of the machine, the projecting rod 45 is pushed up a little by the rotor 71 that causes a small angle of reversible rotation by the ball, or by the solenoid that closes the drive circuit by the ball. . At that time, the upstream end 13 of the ball passage 12
When the replenishment balls are filled up to the point where the sensing piece 6 is pressed down by the weight of the balls as described above, the stop plate 53
Since the notches 51 and 55 of the inhibiting piece 49 match the locking protrusion 47 of the actuating plate 37 as shown in FIGS. 1 and 2, the actuating plate 37 is rotated by the parallel links 38 and 38. As shown in FIG. 6, the locking claw 44 projects into the ball passage 12 from the locking claw entrance/exit hole 24 to prevent the supplementary ball x above the tip of the claw from flowing down.
On the other hand, while the actuating plate 37 is rising as described above, the swing prevention pin 46 moves upward together with the actuating plate 37 and comes off from the stop edge 31 of the first stopper 27 as shown in FIG. The stopper 27 rotates clockwise due to the weight of the replenishment balls x acting on the surface 28, and releases all of the replenishment balls x downstream from the tip of the locking pawl 44 into the prize ball release path 72. The discharge is fast and the actuating plate 37
The first stopper 27 returns to the angle shown in FIG. 7 due to its own weight, and the lowering of the actuating plate 37 causes the locking pawl 4 to move downward.
Immediately before the finger 4 moves its toe into the locking pawl entrance/exit hole 24, the swing prevention pin 46 lowers and engages with the stop edge 31. Immediately after that, the locking pawl 44 is connected to the entrance/exit hole 24.
Since the replenishment ball x retreats inward and loses the locking action of the upstream replenishment ball x by the toe, the replenishment ball x again descends until it hits the first and second stopper surfaces 28, 34, and as a result of the above, the prize ball of the prize ball The discharge into the discharge path 72 and the replenishment of the balls into the ball passage 12 are completed.

When the supplementary balls x riding on the sensing piece 6 of the guide gutter 3 run out, the receiving surface 54 of the stop plate 53 advances into the upstream end 13 of the ball passage 12 as shown by the chain line in FIG. 2, and the first connecting piece 60 , the sensing piece 6 is flipped up via the interlocking plate 59 and the second connecting piece 61, and the notch 55 is rotationally moved so that the abutting edge 56 corresponds to the locking protrusion 47 of the actuating plate 37. As described above, the receiving surface 54 is located at the upstream end 1.
3, the replenishment ball x flows into the ball passage 12 from the upstream end 13, and even if a safe ball occurs, the actuating plate 37 hits the locking protrusion 47 against the abutment edge 56, and the ball Since the target does not rise, the swing prevention pin 4
6 remains engaged with the stop edge 31 of the first stopper 27, and the ejection of the prize ball is interrupted.

When there are no more balls in the ball path 12, the inhibiting piece 49 has a receiving surface 5 in the ball path 12 due to its weight balance.
0 is advanced, and at the same time, the abutting edge 52 is brought into contact with the locking protrusion 47 of the actuating plate 37 to restrain the upward movement of the actuating plate 37 and prevent the ejecting operation of the prize ball.

When the end of the ball removal lever 63 is momentarily lifted with a solenoid or hand, etc. at the end of the work day, the first contact edge 36 of the second stopper 33 is disengaged from the engagement edge 67, and the second stopper is moved to the second stopper. The weight of the replenishment ball x acting on the stopper surface 34 causes it to rotate counterclockwise as shown by the arrow in FIG. 73. At that time, the restraint lever 66 is
8, the engagement edge 67 is brought into contact with the contact edge 30 of the first stopper 27 as shown in FIG. 8, thereby preventing clockwise rotation of the stopper 27 and protecting the swing prevention pin 46. . Even if the ball removal lever 63 is released from its lifting position during ball removal, the elastic force of the pull-up spring 69 causes the locking protrusion 65 to come into contact with the second contact edge 36a as shown in FIG. will not rotate clockwise under its own weight and return. After removing the ball, press the lever 63 for removing the ball.
When you lift it again, it will automatically move to the second stopper surface 34.
Perform a return rotation to make it vertical.

The other part 74 is a ball that is manually tilted in the direction of the arrow in FIG. This is a stop lever.

(Effects of the Invention) The device of the present invention moves upward due to the generation of the safe ball, projects the locking claw 44 into the ball passage 12 from any of the plurality of locking claw entry/exit holes 24, and causes the ball x above the tip of the toe to move upward. A locking pawl 44 is provided on the actuating plate 37 to prevent the ball from flowing down and release the ball below the toe from the end of the ball passage 12. Since the number of prize balls to be released when balls are generated can be freely changed, the locking pawl can be freely attached to any of the shaft supports 43 according to requests such as how many prize balls to be released at one time. It has the effect of being able to fit into.
