Is provided. It should be noted that a printing device is built in the back surface of the receipt issuing port 13 as a matter of course. The balls returned to the ball return device 9 are collected in the storage tank 30 via a return passage (not shown). In addition, the ball return device 9
It may be detachable from the pachinko island stand 1.

As shown in FIG. 4, the doffing and feeding device 15 includes a first doffing and feeding device 16 having a long length and a second doffing and feeding device 17 having a short length. ing.
The upper part of the first doffing and conveying apparatus 16 faces the distribution tank 18 provided at the uppermost part of the pachinko island stand 1, and the upper part of the second doffing and conveying apparatus 17 is in the middle of the pachinko island stand 1. It faces the relay tank 19 provided.

The distribution tank 18 communicates on the left and right with the distribution path 3. After the balls discharged by the first ball-lifting device 16 are temporarily stored in the distribution tank 18, the distribution tank 3
Flow down. The distribution tank 18 includes the relay tank 1.
When the number of balls stored in the distribution tank 18 exceeds a predetermined amount, the balls overflow from the reflux pipe 20 and are returned to the relay tank 19. Further, the height position of the distribution tank 18 may be a position lower than the conventional position. Conventionally, since the equalizing device for equalizing the ball amount between the pachinko islands 1 is performed between the adjacent distribution tanks 18, it is necessary to place the entire distribution tank 18 on the top of the pachinko islands 1. Because there was. On the other hand, in the present embodiment, since it is not necessary to provide an equalizing device, almost the entire distribution tank 18 can be housed inside the pachinko island stand 1 to lower the height position as shown in FIG. By doing so, the length of the first doffing and feeding device 16 can be shortened to some extent, and in this respect also, the doffing and feeding efficiency of the first doffing and feeding device 16 is improved, and the first doffing and feeding device 16 is improved. 16 is reduced.

The relay tank 19 includes a storage tank 30.
And a recirculation gutter 21 extends from below. As shown in FIG. 1, the lower end of the recirculation gutter 21 faces a later-described falling plate 33 which is provided at the center of the storage tank 30 and is inclined to return the ball flowing out of the relay tank 19 to the storage tank 30. Like that. In addition, the first doffing device 16 and the second doffing device 17
Is configured such that a lifting belt is stretched around the outer periphery of one motor pulley 22 disposed at the lower part of the motor pulley 22. Accordingly, the first doffing device 16 and the second doffing device 17 are driven by the same drive source, and upwardly discharge balls supplied from an outflow gutter 37 of the storage tank 30 which will be described later. Will do. Further, the first doffing device 16 and the second doffing device 17 are, in the illustrated embodiment,
Both have a structure having a ball polishing member. Then
Since the second ball-lifting device 17 only lifts up to almost the upper portion of the storage tank 30, the circulation speed of the balls polished and transported by the second ball-lifting device 17 is high, and the polishing process is performed efficiently. . Therefore, the first doffing and feeding device 16 having a long length is used.
Most of the balls discharged to the distribution path 3 have been subjected to ball polishing by the second short ball discharging device 17, and in the first ball discharging device 16, the ball polishing capacity Therefore, even if a large amount of balls are stored in the storage tank 30, it is not necessary to operate the storage tank 30 at a high rotation as in the related art, so that the burden is reduced and the number of failures is reduced.

Further, when a ball polishing member is used in the first doffing and feeding device 16, the replacement of the ball polishing member is troublesome because the length of the first doffing and feeding device 16 is long. In addition, since the dirt on the ball polishing member of the first ball discharging device 16 is small, the frequency of replacing the ball polishing member can be reduced. On the other hand, the polished member of the second doffing and feeding device 17 having a short length and being easily exchanged may be simply exchanged, so that maintenance and management as a whole is easy. That is, in the present embodiment,
As shown in FIG. 3, the first doffing and feeding device 16 is mainly used for discharging necessary balls to the distribution path 3, and the second doffing and feeding device 17 is mainly used for ball polishing as shown in FIG. 2. Used for different purposes. Thereby, a large amount of balls can be efficiently circulated inside the pachinko island stand 1 as compared with the related art.

The structure of the storage tank 30 for supplying the balls to the above-described ball discharging device 15 will be described with reference to FIGS. Almost the entire lower space inside the pachinko island 1 is provided with a storage tank 30 as shown in FIG. And this storage tank 30 is provided in the pachinko island stand 1 on both sides of the doffing and conveying device 15. So 1
Two storage tanks 30 built in one pachinko island stand 1
Is the number obtained by dividing the total amount of balls used in the game hall by the number of pachinko islands 1 installed in the game hall, and is usually around 100,000.

The inside of the storage tank 30 is divided into three as shown in FIGS. That is, a pair of partition walls 31 are erected at a predetermined interval substantially at the center of the storage tank 30, and the inside of the partition walls 31 is a ball supply passage 32 through which the balls supplied to the ball discharging device 15 pass. The outside of the partition wall 31 serves as a storage unit 34 in which the balls dropped or returned from the out ball box 6 and the ball returning device 9 are stored. The upper part of the partition wall 31 is closed by a falling plate 33 which is inclined from the doffing and conveying device 15 side toward the opposite side. And the falling plate 3
As described above, the end of the return gutter 21 faces the upstream side of 3, so that the balls flowing out of the return gutter 21 flow down the plate 33.
Falling over the entire area of the storage sections 34 on both sides while flowing over the upper surface of the storage section 34. However, even though the entire area of the storage section 34 is not included,
At the time when the ball flows out from 1, the ball that flows down has a good momentum, so that the ball does not drop much on the upstream side of the falling plate 33. But,
Since the force of the ball flowing down from the middle to the downstream of the falling plate 33 is also weakened, many balls fall. In addition, the bottom surface of the storage tank 30 is inclined downward toward the ball lifting device 15 in both the ball supply passage 32 and the storage unit 34.

At the lower end of the partition wall 31, inlets 35 are opened alternately from left to right from upstream to downstream, and the inlet 35 is provided with a guide chute 36 as shown in FIG. The guide chute 36 extends from the upper end of the guide piece 36a and the guide piece 36a erected so as to guide the ball flowing down the bottom of the storage section 34 toward the inflow port 35, and extends backward. It is composed of a bottom surface and a protection plate 36b that keeps an interval larger than the diameter of the ball. The protection plate 36b protects the ball which is going to flow into the inflow port 35 so as not to receive the pressure of the ball located above the protection plate 36b as shown in FIGS. The ball of the storage section 34 is smoothly guided to the ball supply passage 32 in cooperation with 36a.

The lower end of the ball supply passage 32 communicates with an outflow gutter 37 for guiding the ball to the ball lifting device 15 as shown in FIG. The first doffing device 16 and the second doffing device 17 are led to the doffing device 15. Since the ball inlet of the doffing and feeding device 15 faces the one storage tank 30, a bypass gutter 38 is extended from the ball supply passage 32 of the other storage tank 30 of the pachinko island stand 1. The lower end of the bypass gutter 38 is connected to the ball supply passage 32 of one storage tank 30 or the storage unit 3.
4 is connected. Thereby, all the balls stored in the two storage tanks 30 built in the pachinko island 1 are supplied to the ball lifting device 15 and circulate inside the pachinko island 1.

In the storage tank 30 constructed as described above, a ball supply passage 32 for supplying the balls to the doffing and feeding device 15 is formed at the center thereof, so that the stored balls can be smoothly doffed. The storage unit 34 is supplied to the
The movement of the balls from the ball to the ball supply passage 32 is performed by the inflow ports 35 formed from the upstream to the downstream, so that the balls stored in any positions of the storage tank 30 can be reliably transferred to the ball supply passage 32. It flows in and is polished by the ball-lifting device 15, and is constantly circulating inside the pachinko island stand 1. That is, since there is almost no ball staying at one place in the storage tank 30 for a long period of time, there is no disadvantage that the stored ball is rusted by moisture. Also,
Since the storage tank 30 has a structure for directly receiving the used balls discharged from the pachinko machine 2, it is possible to save the labor and cost of laying the out-ball collection path inclined toward the doffing and conveying device 15 as in the related art. There are advantages.

The embodiment has been described above.
In the above embodiment, the first doffing device 16 and the second doffing device 17 are driven by the same drive source, but may be driven by different drive sources. Moreover, although the apparatus using the lifting belt as the ball frying apparatus has been described, a ball frying apparatus for mixing and fusing granular ball polishing material and balls may be used. Furthermore, although the ball return device 9 is provided corresponding to each pachinko machine 2, it is not always necessary to correspond to each pachinko machine 2, but the point is that the prize ball obtained by the player is transferred to the pachinko island stand. It is sufficient that the ball return device is installed in such a position that it can be returned to the factory.
