[0003]

However, in such a conventional prize ball payout device, the ball pressure of the prize balls waiting in a row in the supply passage 101 is directly applied to the claw portion 102 of the sprocket 103. Since the drive motor 104 is overloaded and the prize ball payout operation is frequently performed, the drive motor 104 may be damaged due to short-term use. In addition, since the prize balls are discharged by the claws 102 of the sprocket 103 so that the prize balls are discharged one by one, the payout takes a long time, and the wear of the sprocket 103 causes ball catching or the number of dispensed balls is not accurate. There is a problem such as. Therefore, the present invention has been made in view of the above problems, and a prize for a novel pachinko machine in which the payout operation of the prize ball can be performed without being substantially affected by the ball pressure of the prize ball that is continuously supplied. An object is to provide a ball payout device.

In order to achieve the above object, a prize ball payout device of the present invention is installed so as to correspond to a supply passage through which prize balls are continuously supplied and an orthogonal shape to the supply passage. And a motor for rotating the screw member, the screw member having a spiral ball feed projection provided on the outer peripheral surface thereof, the supply passage being located on the side of the screw member, Is provided with a continuous ball receiving rack for receiving the first free gift ball, and the screw member is configured to discharge the free gift balls on the ball receiving rack one by one to the discharge passage below the supply passage.

[0005]

Function: The prize balls supplied into the supply passage are received by the upper surface of the ball receiving rack and stand by in a continuous state. Next, with the rotation of the screw member driven by the motor, the spherical balls sending protrusions discharge the prize balls on the upper surface of the ball receiving rack one by one to the discharging passage. After that, repeat the same operation,
The prize balls will be sequentially discharged to the discharge passage. This makes it possible to discharge the prize ball with almost no ball pressure applied to the screw member, and because a large load is not applied to the motor, it is possible to use a small motor and downsize the entire device. You can also do it.
