A center shaft 2 that protrudes rearward is located within the circular projecting wall 2 of the mounting plate 1.
2 is passed through the shaft insertion hole 4 and the second shaft insertion hole 14, and a supported rotating body 23 is loosely fitted therein.

As shown in FIG. 1, the rotary body 23 has a first ball socket 24 with a narrow left and right width that matches the front side of the upper safe ball outflow hole 5, and an upper safe ball outflow hole 5 as shown in FIG. A second ball socket 25 with a wide left and right width with a protruding baffle plate 26 is provided above and below in front of the ball socket 25, and the bottom plate 27 of the second ball socket 25 is inclined to the lower left in FIG. Attach a weight 28 to stabilize the ball with the first ball socket 24 facing downward as shown in the figure.

The rotating body 23 is rotated approximately 150 degrees clockwise by the weight 28 from the angle shown in FIG. 1 to the angle shown in FIG. 2 with the second ball socket 25 facing upward. The weight causes the ball to rotate approximately 150° counterclockwise, resulting in the angle shown in FIG. 1 with the first ball socket 24 facing upward.

Note that the safe balls that entered the first hit ball socket 24 and were captured flow out from the upper safe ball outflow hole 5 to the rear side and are transferred to the second hit ball socket 2.
The safe balls that entered 5 and were captured are sent to the lower safe ball outflow hole 6.
It flows out to the rear.

On the back side of the mounting plate 1, between the shaft insertion hole 4 and the second shaft insertion hole 14, a tube member 29 having a protruding cam 30 having a vertical locking surface 31 on the side is fitted onto the central shaft 22 and fixed. The angle is determined so that the vertical locking surface 31 is vertical when the ball socket 24 is at an upward angle as shown in FIG.

A slider 32 is fit into the sliding groove 10 so as to be able to move up and down freely, its lowering position is determined by a stop pin 34, and the rear side is lightly pressed by a presser plate 15.

The slider 32 is provided with a cam locking piece 33 that projects laterally from the small protrusion 9', and the vertical locking surface of the cam 30 is fixed at an angle where the first ball socket 24 of the rotating body 23 is upward. 31 as shown in FIG.
3 is restrained from rotating.

Reference numeral 35 is a swinging piece for stacking rod operation in which the support shaft 36 is fitted into the large shaft support portion 17 of the second guide frame 11, and a weight piece 37 is provided in front of the support shaft 36 to make the front side heavier and the rear side heavier. A pressure-receiving surface 38 that is in contact with the safe balls falling from the outflow drop hole 13 is provided on the side, tilting downward to the right, and a pressure-receiving pin 39 that protrudes outward from the opening 19 is also provided, and the front side is lowered by the weight piece 37. At this time, the pressure receiving pin 39 is brought into contact with the cushioning material 21 of the stop edge 20 from below.

Moreover, the slider 3 is attached to the swing piece 35 from the front side of the support shaft 36.
A protruding piece 40 is provided that protrudes from the lower surface of 2.

In the structure of the above embodiment, as shown in FIG. When the rotating body 23 is in contact with the rotating body 23, the rotating body 23 is restrained from rotating clockwise by the weight 28.

When the hit ball enters the first hit ball socket 24 and becomes a safe ball, it passes through the upper safe ball outflow hole 5, the guide plate 8, and falls from the outflow drop hole 13 onto the pressure receiving surface 38 of the rocking piece 35. Due to its weight, the swing piece 35 flips up the front side of the support shaft 36, and the push-up piece 40 pushes up the slider 32 as shown in FIG.

Therefore, the vertical locking surface 31 of the cam 30 is released, and the rotating body 23 is rotated to the angle shown in FIG. 2 by the weight 28.

On the other hand, the swing piece 35 whose front side has been flipped up as described above moves the pressure receiving pin 39 toward the stop edge 2 by swinging down the pressure receiving surface 38.
0 (buffer material 21) and the safe ball moves downward to the opening 18.
At the same time, the pressure receiving surface 38 is raised again.

Therefore, although the pressure receiving pin 39 butts against the lower surface of the buffer material 21, the impact at that time is absorbed by the buffer material 21, and the swinging piece 35 does not vibrate in a reactionary manner.

In the state shown in FIG. 2, when a hit ball enters the second hit ball socket 25, the baffle plate 26 prevents it from entering the upper safe ball outflow hole 5, so the ball rotates counterclockwise against the weight 28, and the cam 30 The vertical locking surface 31 of the slider 32 is brought into contact with the cam locking piece 33 of the slider 32 from below as shown in FIG. 7, and the slider 32 is moved upward until it assumes the angle shown in FIG. The mover 32 lowers under its own weight and brings the cam locking piece 33 into contact with the vertical locking surface 31 as shown in FIG. 5, thereby restraining the rotation of the rotating body 23 in the clockwise direction.

As clarified in the above embodiment, the present invention has the swinging piece 3.
5 has a structure in which a cushioning material 21 such as rubber is attached to the stop edge 20 of the guide frame 11 against which the pressure receiving pin 39 hits when the front side is lowered, so that after lowering the pressure receiving surface 38, the weight of the safe ball is When lowering the heavy front side,
Since the pressure receiving pin 39 abuts against the buffer material 21 and the shock is absorbed, there is an effect that the reaction vibration of the swing piece 35 can be eliminated and the swing piece 35 can be quickly stabilized.
