DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a system for controlling the circulation of a group of pachinko balls which are circulated and recovered in a pachinko machine.

[0002]

2. Description of the Related Art A revolving pachinko machine uses a fixed number of pachinko balls enclosed in the machine, sequentially fires pachinko balls sent to a hitting position, collects the fired pachinko balls, and returns to a hitting position. It is configured to feed and circulate in the pachinko machine.

[0003]

SUMMARY OF THE INVENTION It is an object of the present invention to eliminate a shortage of pachinko balls which are circulated in a pachinko machine and are returned to a hitting position after waiting at a standby position. Things.

[0004]

SUMMARY OF THE INVENTION A pachinko ball circulation control device according to the present invention is provided in the middle of the circulation path of a group of pachinko balls which are fired from a hitting position on a firing rail and returned to the hitting position again. A standby guiding section for waiting for the pachinko balls to be sent to the hitting ball position, standby ball detecting means for detecting a shortage of the number of pachinko balls waiting on the standby guiding section, and pachinko balls operated by a detection signal of the standby ball detecting means And a ball sending-out mechanism for supplying the ball to the standby guiding section.

[0005]

When the number of pachinko balls waiting in the waiting guide portion provided in the middle of the circulation path of the group of pachinko balls is insufficient, the waiting ball detection sensor detects the shortage of pachinko balls, and the detection of the waiting ball detection sensor is performed. The ball sending-out mechanism is operated by the signal, and the pachinko balls are supplied to the standby guiding section.

[0006]

Since the present invention is configured as described above, when the number of pachinko balls waiting in the standby guiding section is insufficient, it is possible to accurately feed the insufficient pachinko balls to the standby guiding section and supply them. It is possible to prevent a problem that the number of pachinko balls on standby is insufficient. Therefore, the pachinko balls to be reduced to the hitting position can be constantly secured, and the pachinko balls can be continuously fed from the standby guiding section to the hitting position.

Each pachinko ball stored in the sixth circulation passage 46F slides on both cleaning members 66 and moves while rotating intermittently while being intermittently fed toward the seventh circulation passage 46G, and moves to the storage guiding portion 52c. Each of the stored pachinko balls is cleaned and polished with dirt and the like adhering to the surface of the pachinko balls by the two cleaning members 66, and is stored and guided.
It is sent out from C and sent to the standby guidance section 52E.

Next, the operation and effect of the embodiment having the above configuration will be described. In the present example, the pachinko balls to be sent to the hitting position are arranged in a line in the middle of a circulation path in which a group of pachinko balls which are fired from the hitting position on the firing rail 4 and returned to the hitting position are circulated and stand by. And a standby ball detection switch 75 for detecting a shortage of the number of pachinko balls waiting in the standby guide unit 52D.
And a ball delivery mechanism that is intermittently driven by the detection signal of the standby ball detection switch 75 and sends out pachinko balls from the storage guiding unit 52C to the standby guiding unit 52D to replenish them. For this reason, when the number of pachinko balls waiting in the standby guiding unit 52D is insufficient, the shortage of pachinko balls can be accurately fed to the standby guiding unit 52D for replenishment. It is possible to prevent inconvenience occurring. Therefore, it is possible to constantly secure the pachinko balls to be reduced to the hit ball position and to send the pachinko balls from the standby guiding unit 52D to the hit ball position without interruption.
