Description

Detailed Description of the Invention

[0001]

This invention relates to a pachinko machine,
The present invention relates to an out-of-ball detection device that detects a pachinko ball that is sent from a ball tank in which a group of pachinko balls is stored and is on standby.

[0002]

2. Description of the Related Art In a pachinko machine, a player waits the number of pachinko balls necessary for paying out as prize balls to a player in a ball passage from a ball tank in which a group of pachinko balls is stored to a ball payout control mechanism. It is necessary to supply the required number of waiting balls to the ball passage each time they are paid out.

[0003]

SUMMARY OF THE INVENTION An object of the present invention is to provide an out-of-ball detecting device which enables detection of a pachinko ball at a desired position on the way of a ball passage where a ball tank reaches a ball payout control mechanism.

[0004]

A ball breakage detecting device in a pachinko machine according to the present invention has a ball passage near a ball passage through which a pachinko ball sent from a ball tank toward a ball payout control mechanism passes and stands by. It has a configuration in which a complementary ball sensor for detecting the ball breakage in the contactless manner is installed so that the detection position can be changed.

[0005]

[Function] A lack of waiting balls waiting in the ball passage is detected without contact by a complementary ball sensor installed near the ball passage through which the pachinko ball sent from the ball tank toward the ball ejection control mechanism passes and stands by. , The position at which the complementary ball sensor detects a ball break is changed to change the limit of the number of pachinko balls waiting in the ball passage.

[0006]

Since the present invention is configured as described above, it is possible to make the detecting mechanism compact and simple for detecting a ball break in the ball passage where the pachinko ball sent from the ball tank stands by. At the same time, this detection mechanism can be easily attached and detached at a desired position. Also, since the position at which the replenishment sensor detects out-of-balls can be changed, the minimum required number of standby balls can be set according to the number of pay-out balls, and even if the number of pay-out balls increases or decreases The pachinko ball of can be supplied to the ball passage by following the payout ball.
