Even if the prize ball A remains, the height of the entire prize ball payout means 33 can be reduced.

Since the sensing arm 92 is formed to be long in the direction of the prize ball storage passage 34, the sensation arm 92 does not swing unstably due to individual prize balls A in the prize ball storage passage 34. Malfunction of the ball out confirmation switch 39 can be prevented. Since the sensing arm 92 is pivotally supported by the pivot pin 93 on the upper side in the passage direction, when the sensing arm 92 protrudes into the prize ball storage passage 34, the prize ball A is inserted into the prize ball storage passage 34.
, The sensing arm 92 allows the prize ball storage passage 34
The prize ball A does not get clogged within. Therefore, recovery after ball clogging or the like is easy.

According to the second aspect of the present invention, in the first aspect of the present invention, a gently inclined passage portion 34a in which the prize ball storing passage 34 is gently inclined is provided at the upper end side, and the gently inclined passage portion 34a is provided. Since the sensing arm 92 is disposed in the portion 34a, the following remarkable effects are obtained. When replenishing the prize ball A into the prize ball storage passage 34, the sensing arm 92 is arranged in the gentle slope passage portion 34a where the moving speed is slow, so the sensing arm 92 comes into contact with the prize ball A and swings. In spite of this, damage to the sensing arm 92 due to contact with the prize ball A can be reduced.

According to the third aspect of the present invention, in the second aspect of the present invention, the sensing arm 92 is disposed above the gentle inclination passage portion 34a, and the stopper 96 for restricting the lowering of the sensing arm 92 is provided. , The following remarkable effects are obtained. Since the sensing arm 92 is located above the gentle inclined passage portion 34a, when the prize ball A in the gentle inclined passage portion 34a is exhausted, the sensing arm 92 can be protruded by its own weight into the gentle inclined passage portion 34a, and the sensing can be performed. The structure on the arm 92 side can be simplified.

Since the stopper 96 for restricting the lowering of the sensing arm 92 is provided, the sensing arm 92 is
Despite being on the upper side of 34a, this sensing arm 92 does not protrude too far into the shallow passage 34a. Therefore, when the prize ball A passes through the gentle slope passage portion 34a at the time of restoration, the moving speed of the prize ball A also decreases, and the prize ball A
Without violently knocking the sensing arm 92 upwards,
The damage of the sensing arm 92 can be prevented.
