Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a circulation control device for a group of pachinko balls that are circulated and collected in a pachinko machine for circulation in a pachinko machine.

[0002]

2. Description of the Related Art In a circulating pachinko machine, a fixed number of pachinko balls enclosed in the machine are used, and the pachinko balls sent to the hitting position are sequentially ejected, and the ejected pachinko balls are recovered to the hitting position again. It is configured to feed and circulate inside the pachinko machine.

[0003]

SUMMARY OF THE INVENTION It is an object of the present invention to cope with a shortage of the storage amount of pachinko balls collected and stored after launch in a circulating pachinko machine.

[0004]

A pachinko ball circulation control device of the present invention is arranged in the middle of a circulation path in which a group of pachinko balls that are shot from a hitting position and then returned to the hitting position circulate. , A storage guide section for storing the pachinko balls collected after launch, a detection means for detecting a shortage of the storage quantity of the pachinko balls in the storage guide section, and a shortage of the storage quantity based on a detection signal of the detection means. Is provided to the outside.

[0005]

[Function] When the storage amount of the pachinko balls in the storage guiding portion for storing the pachinko balls collected after the launch is arranged in the middle of the circulation path in which the pachinko balls of the first group circulate, the insufficient detection of the pachinko balls is detected. The means sends a detection signal, and the notification means notifies the outside of the insufficient state of the amount of pachinko balls stored in the storage guide portion.

[0006]

Since the present invention is configured as described above, even if an abnormal state in which the amount of pachinko balls stored in the storage guide portion is insufficient due to a cause such as ball clogging occurs, this abnormal state Since the abnormality is notified to the outside at the time of occurrence, it is possible to immediately eliminate the cause of the abnormal state and deal with the insufficient amount of pachinko balls stored in the storage guide.

The storage guiding unit 52C is provided with a storage ball detecting switch 77 for detecting a shortage of the amount of pachinko balls stored in the storage guiding unit 52C,
Based on the detection signal of the storage ball detection switch 77, the abnormality notifying means notifies the outside of the shortage of the storage amount of pachinko balls.

Therefore, even if an abnormal state occurs in which the storage amount of the pachinko balls in the storage guide portion 52C is insufficient due to a ball clogging or the like, the abnormality is notified to the outside when the abnormal state occurs. Therefore, the cause of the abnormal state can be immediately removed to cope with the insufficient amount of pachinko balls stored in the storage guiding portion 52C.
