The closing member 71 capable of closing the ball emitting portion 45 is exposed,
By providing a synchronizing means for synchronizing the closing member 71 and the rotation of the rotary lever 42, the closing member 71 is moved to release the sphere releasing portion 45 when releasing the sphere, and the sphere emitting portion is opened during the other period. It is configured to close 45.

That is, in the embodiment shown in FIGS. 3 to 7,
As the first cam means on the side of the rotary lever 42, a first cam portion 47 having a projection shape with an increased distance from the center is formed coaxially with the rotary lever 42. On the other hand, a second cam portion 72 corresponding to the first cam portion 47 is provided in a mountain shape in the middle of the length of the closing member 71 on the side of the closing member 71 described later.

According to the illustrated embodiment, the closing member 71 is a lever member having one end rotatably mounted on a shaft, and a spring 73 is wound around the shaft mounting side as a biasing means. The closing member 71 is always biased upward in the drawing. On the other hand, at the tip of the closing member 71, a closing piece 74 for closing the above-mentioned ball discharging portion 45 is extended.
