Is in a ball-cut state with its rotation stopped and locked,
The pachinko ball w is not supplied through the ball passage 23.

When the solenoid 36 is energized in such a ball-cut state, the plunger 36a is sucked into the main body 36b, and the stopper member 35 receives the urging force of the coil spring 49 as shown in FIG. The ball cutting stop portion 3 is rotated counterclockwise around the support shaft 43 in opposition.
The engagement between 5f and the engagement protrusion 34b of the stopper cam wheel 34 is released. Accordingly, the ball cutting wheel 31 rotates under the own weight of the pachinko ball in the ball passage 23, and the stopper cam wheel 34 also starts rotating clockwise integrally with the second gear 33.

When the stopper cam wheel 34 rotates by a predetermined angle, the power to the solenoid 36 is cut off based on the detection signal of the detection sensor 37, and the solenoid 36 is returned to its original state, that is, the plunger 36a extends from the inside of the main body 36b.

This can prevent an excessive supply of pachinko balls w.

In addition, when emergency measures are taken, the end of the connecting member 45 extended out of the device case 20 is operated as an adjusting piece without removing the lid case 22 of the device case 20 from the base case 21. Thereby, the stopper member 35 can be rotated around the support shaft 43, and the plunger 36a of the solenoid 36 is connected to the main body 36b.
Can be taken in and out, and workability can be improved.

The stopper member 35 is not only substantially L-shaped and formed relatively small, but also has a support shaft 43, that is, a fulcrum, for connecting the long side portion 35a and the short side portion 35b. The stop portion 35f and the emergency stop portion 35g, which are the action points of the stopper member 35, are the middle and short sides 3a of the long side 35a.
5b, the connecting point of the solenoid 36 with the plunger 36a, which is the point of force of the stopper member 35, is located on the distal side of the long side 35a.
In this case, it is possible to use a small-sized and low-power one, which can contribute to downsizing of the ball supply device 5.

Further, a connecting member 45 is interposed between the tip of the long side 35a of the stopper member 35 and the plunger 36a of the solenoid 36, and one end of the connecting member 45 and the long side 35a of the stopper member 35 are connected. Since the distal end and the connecting pin 46 are connected to be able to bend around the connecting pin 46, the arrangement of the solenoid 36 can be appropriately set by changing the bending angle, and this also contributes to downsizing of the ball supply device 5. be able to.

Further, the solenoid 36 has a
The plunger 36a performs a one-stroke operation by repeating this operation. For example, from the normal state in which the plunger 36a extends out of the main body 36b when the power is not supplied as shown in FIG. 9A, the first power supply is performed for 0.3 seconds, and the plan is supplied as shown in FIG. 9B. Jar 36a into body 3
A predetermined size L1 is sucked into 6b. During a lapse of 0.5 seconds thereafter, the plunger 36a falls due to its own weight as shown in FIG.
(<L1). Subsequently, the second energization is performed for 0.3 seconds, and as shown in FIG.
6a is sucked L (about 3 mm) for one stroke. As a result, even if the load on the plunger 36a is large, the plunger 36a does not become locked during the suction, and the plunger 36 can be reliably operated for one stroke, thereby improving the reliability of operation. Can be.
