As shown by the chain line in FIG. 4, the rotary body 11 rotates forward by 120 degrees and flows backward through the ball passage 10 from the ball inlet 2.

On the other hand, the movable blade pieces 3 and 3
The forward rotation of 20 degrees causes the engagement walls 15, 15 to move rearward and disengage with the projections 5, 5 of the movable wing pieces 3, 3.
As shown by the chain line in FIG. 2, it tilts outward by its own weight and opens. Thereafter, each time the ball passes between the movable wing pieces 3, 3, the rotating body 11 makes a normal rotation of 120 ° each time, and the movable wing pieces 3, 3 stand up once and tilt twice. And do it.

In the state where the movable wing pieces 3 and 3 stand up as shown by the solid line in FIG. 5, when a ball entered from the ball introduction port 9 of the box frame 8 is received by the ball receiving surface 18 of the lever piece 16, The lever piece 16 rotates upward (clockwise) as shown by the chain line in FIG. 5 due to its ball weight, and the feed claw 20 thereof contacts the ball contact piece 14b of the rotating body 11 to rotate the rotating body 11 by 120 degrees. Turn forward. As a result, the upright movable wing pieces 3, 3 tilt. The operations described so far are known.

As shown by the solid line in FIG. 6, when the movable wing pieces 3 and 3 are tilted and opened twice from the standing position, when the sphere is guided to the sphere introduction port 9, the sphere is moved to the lever piece 16. The lever piece 16 rotates upward (clockwise) as indicated by the chain line in FIG. Then, the pushing member 27 moves the engaging member 26 of the cam member 23 upward to rotate the cam member 23 downward (counterclockwise) as shown by a dashed line in FIG. As a result, the projection 22 of the cam member 23 comes into contact with and engages with the engagement piece 21 of the rotating body 11 to invert the rotating body 11 by 120 degrees as shown by the chain line in FIG. Therefore, in this state, even if a sphere enters between the movable wing pieces 3 and 3 to rotate the rotating body 11 forward by 120 degrees, the rotating body 11 only returns to the position shown by the solid line in FIG. Tilts and opens again without standing up. In this manner, by alternately repeating the normal rotation and the reverse rotation of the rotating body 11, the movable wing pieces 3, 3 can be kept tilting semi-permanently.

In the above-mentioned embodiment, the safe ball receiver which opens twice is explained. However, the present invention is not limited to this, and any safe ball receiver which opens at least twice or more can be applied. It is possible. It goes without saying that the number of engagement pieces can also be arbitrarily selected.
