2. Description of the Related Art Conventionally, as a ball dispensing device for a pachinko machine,
A plurality of supply passages through which the pachinko balls continuously flow down, a plurality of rotating bodies alternately having concave and convex portions for receiving or receiving the pachinko balls one by one facing the respective supply passages; There is known a supply passage provided with a discharge passage through which pachinko balls are discharged. In the ball dispensing device having such a configuration, a pachinko ball detection switch is provided in correspondence with each discharge passage in order to count the paid out pachinko balls, so that a plurality of pachinko ball detectors are required and cost is increased. Had become.

In view of the above, recently, pachinko balls discharged from a rotating body to a discharge passage are discharged while being merged in a line below the rotating body, or pachinko balls received in a guide groove of the rotating body. Are discharged while being merged in a line in the middle of dispensing (for example, Japanese Utility Model Laid-Open No. 4-13190 and Japanese Patent Laid-Open No. 10-127).
No. 898).

[0004]

By the way, as described in the prior art, if the pachinko balls dispensed below the rotating body are to be merged in a line, the space required for merging the passages becomes extra. And the entire apparatus becomes large. On the other hand, in order to minimize the space at the passage merging, the merging must be made abruptly, and as a result, the paid-out pachinko balls collide with each other to cause ball clogging. I was

In the latter case, a stable merging can be realized by merging the pachinko balls while paying them out, but since the ball pressure of the pachinko balls waiting in the supply passage is directly applied to the rotating body, There is a problem that a large load is applied to the drive motor, and the drive motor is broken down or the pachinko ball cannot be dispensed smoothly due to short-term use.

The present invention has been made in view of the above-mentioned problems of the prior art, and an object of the present invention is to smoothly and without pachinko balls in a plurality of supply passages one by one. It is an object of the present invention to provide a ball dispensing device for a pachinko machine that can discharge the ball and reduce the size of the entire device.

[0007]

In order to achieve the above-mentioned object, a ball dispensing device for a pachinko machine according to the present invention comprises a plurality of supply passages through which pachinko balls flow continuously, and a rotation facing each of the supply passages. In a ball discharging device for a pachinko machine, comprising a body and a discharge passage from which pachinko balls in each supply passage are discharged by rotation of the rotating body, the rotating body integrally includes ball feeding means having different spiral directions on an outer peripheral surface. The rotation of the rotating body causes the pachinko balls to converge to a substantially central portion of the rotating body and to be discharged to a discharge passage.

It is preferable that a ball receiving shelf for supporting the leading pachinko ball is provided in the supply passage at a side of the rotating body, and the ball pressure of the pachinko ball waiting in the supply passage is adjusted to the ball receiving shelf. As the ball pressure is not directly applied to the rotating body,
The load applied to the rotating body is reduced, and the rotating body is smoothly rotated, so that the accurate pachinko ball payout operation can be performed.

Further, it is preferable that the ball receiving shelf is formed to have an upward slope toward the discharge passage so that the pachinko balls on the ball receiving shelf are surely transferred by the ball feeding means.

It is preferable that the ball-feeding means is a ball-feeding ridge, and the pitch of the ball-feeding ridge is shifted. Pachinko balls in the supply passage are alternately formed by the right-handed helical-balling ridge and the left-handed helical-ball-feeding ridge. It is good to discharge to the discharge passage.

Further, by providing a plurality of the ball feed projections, a large number of pachinko balls are dispensed in one rotation.
Efficient payout can be made possible.

The ball dispensing device of the present invention is not limited to a ball dispensing device for rented balls or prize balls, but can be similarly applied as a ball discharging device.
