A ball guide plate 8 is pivotally supported by a horizontal shaft 9 and has a ball receiving piece 7 integrally protruding at a different level below the tip part 6, and is pivoted by a horizontal shaft 9. In the substantially horizontal position where the movable blades 3, 3 are lowered, it intervenes below the axis of the movable blades 3, 3 to hold them in an upright state where it is difficult for a ball to enter, and at the same time lowers the rear end and flips up the tip to move the movable blades 3, 3. It is formed so as to be converted into a tilting state.

In the present invention, the ball guide plate 8 is pivotally installed on the guide box 5 so that the rear part thereof is heavier than the front part, and is opposite to the ball outlet 10 of the guide box 5, as shown in FIG. A ratchet gear 12 is coaxially supported on the outer surface of the side wall 11 by the horizontal shaft 9 of the ball guide plate 8, and a window 13 is bored in the rear part of the side wall 11 of the guide box 5, and the ball guide plate exposed through the window 13 is provided with a window 13. A feed control rod 14 is pivotally supported at the rear end of the plate 8 by a pivot 15, and the upper end of the feed control rod 14 is bent to one side to integrally protrude a receiving piece 16 that crosses the upper surface of the ball guiding plate 8. At the same time, a feed pin 17 is provided protruding from the opposite side, a torsion coil spring 18 is inserted into the pivot shaft 15, and one end is engaged with the feed control rod 14, and the other end is engaged with the ball guide plate 8. The feed pin 17 is connected to the ratchet gear 1.
2 teeth Y1, Y2, Y3...Yn, and on the side wall 11 of the guide box 5, a reversal prevention pawl 19 is pivotally supported by a pivot 20, and a torsion coil spring 2 is attached.
1 into the pivot 20, one end of which is engaged with the reversal prevention claw 19, and the other end thereof is engaged with the mounting board 1, so that the reversal prevention claw 19 is connected to the teeth Y of the ratchet gear 12.
1, Y2, Y3, . . . Yn, to control rotation of the ratchet gear 12 in one direction.

The ratchet gear 12 has one tooth formed as a square tooth 23, and a groove 24 into which the feed pin 17 of the feed control rod 14 can be fitted is formed between the square tooth 23 and the tooth Yn. As shown in FIG. 4, when the feed pin 17 is fitted into the recessed groove 24, the ball guide plate 8 is held in a substantially horizontal position with its tip lowered, causing the movable blades 3, 3 to stand up. It is set as follows. Further, the torsion coil spring 18 that biases the feed control rod 14 is set to have such a strength that it slightly succumbs to the force acting on the ball guide plate 8 to lower its rear end due to its own weight.

The present invention has the above-mentioned configuration, and its operation will be explained next. As shown in FIG. 4, when the feed pin 17 of the feed control rod 14 is fitted into the groove 24 of the ratchet gear 12, the ball guide plate 8 is held in a substantially horizontal position, and the movable blades 3, 3 are erected. , the movable wing piece 3,
When the ball B1 enters between the balls 1 and 3, it enters the guide box 5 from the ball inlet 2, flows backward on the upper surface of the ball guide plate 8, and comes into contact with the receiving piece 16 of the feed control rod 14, and the ball B1 enters the guide box 5 from the ball inlet 2, flows backward on the upper surface of the ball guide plate 8, and comes into contact with the receiving piece 16 of the feed control rod 14.
4 is swung rearward against the torsion coil spring 18 as shown by the chain line in FIG. As a result, the feed pin 17 of the feed control rod 14 is removed from the groove 24 of the ratchet gear 12, and the ball guide plate 8 lowers its rear end and flips up its tip, as shown in FIG. Tilt it. Then, the feed control rod 14 descends following the lowering of the rear end of the ball guide plate 8, and the ball B1 flows out from the ball outlet 10 of the guide box 5 to the outside and is released from the ball weight, and at the same time the torsion coil It returns to its original position by the bias of the spring 18, and the feed pin 17 engages with the lower part of the square tooth 23.

When the next hit ball B2 enters between the movable blades 3 and 3 in the tilted state, it rides on the ball receiving piece 7 and uses its weight to lower the tip 6 of the ball guide plate 8 and lower the rear end. The movable wing pieces 3, 3 are raised by raising the movable wing pieces 3, 3. At this time, the feed control rod 14 also rises following the ball guide plate 8, and the feed pin 17 pushes up the square teeth 23 and rotates the ratchet gear 12 clockwise by one tooth. Then, when the hit ball B2 falls from the ball receiving piece 7 and flows backward, and the ball guiding plate 8 is released from the hitting weight, the ball guiding plate 8 lowers its rear end under its own weight and the movable wing pieces 3, 3
Tilt again. When the ball guide plate 8 lowers its rear end, the feed control rod 14 also follows and the feed pin 17 slides on the inclined surface of the tooth Y1 of the ratchet gear 12 against the torsion coil spring 18 and comes off the tip of the tooth. At the same time, it receives the bias of the torsion coil spring 18 and engages with the tooth Y1. Then, each time the third, fourth, etc. hit ball enters, the ball guiding plate 8 repeats the same seesaw action as described above, and each time, the ratchet gear 12 is moved to 1.
The tilting state of the movable blades 3, 3 is continued while rotating tooth by tooth. The tilting state of the movable blade ends when the ratchet gear 12 makes one revolution, the feed pin 17 of the feed control rod 14 fits into the groove 24, and the ball guide plate 8 is held in a substantially horizontal position.

In this way, when the feed pin 17 is fitted into the groove 24, the movable blades 3, 3 are kept in an upright state, and when the first ball enters again, the ratchet gear 12 rotates once. Until then, the movable wing pieces 3, 3 are kept in the same expanded state as described above.

Therefore, the present invention makes it possible to continuously repeat the tilting state of a pair of movable blades a number of times according to the number of teeth of the ratchet gear, and to return the pair of movable blades to the upright state after continuing the tilting state a certain number of times. It is possible to provide a prize winning ball device, thereby increasing the chances of winning and further increasing the interest of players. Furthermore, the tilting state of the pair of movable blades can be changed very easily by selecting a ratchet gear with an arbitrary number of teeth, or by setting a plurality of concave grooves at equal intervals in the ratchet gear into which the feed pin can fit. Can be done. Therefore, by simply replacing the ratchet gear, for example, a simple variable winning ball receiver where the movable blades alternately stand up and tilt and stop, or a variable winning ball receiver that tilts several times in succession and stands up once. There are advantages such as being able to easily provide a variable winning ball receiver that operates repeatedly in cycles.
