2. Description of the Related Art Conventionally, as a pachinko ball circulation system in a pachinko game hall, an all-store circulation system, an independent island system,
And the inter-island circulation system are known. In this system, the pachinko ball counter is installed at a predetermined location, the pachinko balls obtained by the player are returned through the counter, and the pachinko balls are collected in a tank above the ceiling by a lifting machine. This method returns to each pachinko island, but this method has drawbacks such as limitations on facilities due to the size of the store and difficulty in maintenance and inspection.

On the other hand, as an independent island method, for example,
Many are known, such as Japanese Patent Application Laid-Open No. 5-5637 and Japanese Patent Application Laid-Open No. 8-89645. There is a drawback in that the pachinko ball holding quantity varies between pachinko islands, for example, the pachinko balls are not used effectively.

On the other hand, the island-to-island circulation system is disclosed in
As disclosed in JP-A-57985 and JP-A-7-148334, pachinko balls are exchanged between pachinko islands, and there is an advantage that pachinko balls can be effectively used without causing excess or deficiency of pachinko balls between islands. is there.

[0005]

However, according to the conventional island-to-island circulation system, a detector is provided at each part of the pachinko island to detect the amount of pachinko balls, and the pachinko balls are detected based on the signal from the detector. Since the transfer is carried out from a place having a large amount to a place having a small amount, a device having a movable portion for the transfer needs to be installed in each part, and wiring and other control circuits are complicated, and a malfunction easily occurs.

[0006] For example, Japanese Unexamined Patent Publication No. 4-357895 discloses a detector for detecting the amount of pachinko balls held in a tank (upper storage tank) for storing pachinko balls pumped by a lifting machine. A device that operates based on the signal from the detector is interposed in the two systems of the flow path leading to the lifter, and the upper storage tank has a complicated flow path for diverting pachinko balls to each part. As a whole, the internal structure of Pachinko Island is very complicated.

[0007] Japanese Patent Application Laid-Open No. 7-148334 discloses that each pachinko island is connected by a conveyor, and pachinko balls are exchanged between the pachinko islands through the conveyor, so that the power consumption is high and the pachinko island is expensive. It is also difficult to link with existing islands when adding more pachinko machines.Moreover, each pachinko island is equipped with a detector that detects the amount of pachinko balls held, and a conveyor is equipped with a device that opens and closes its path based on the signal from the detector. Because of the interposition, the equipment is large.

SUMMARY OF THE INVENTION Accordingly, it is an object of the present invention to provide a pachinko island having a simple structure so that pachinko balls can be smoothly circulated between the pachinko islands without excess and deficiency, and that the linking and installation work of the pachinko islands can be easily performed.

This pool tank 10 is built in a pachinko island, and a transporter 11 is installed from its lower side toward the collection path 3. . That is, the ball outlet (not shown) of the counter 9 communicates with the collection path 3 via the pool tank 10 and the transporter 11, and the pachinko ball as a prize ball put into the counter 9 by the player is put into the pachinko island. It can be reduced smoothly.

In FIG. 1, reference numerals 12a and 12b denote forward and backward support portions, which will be described later, 13 a lower tank provided below the upper tank, 14 a receiving pipe which communicates with the forward pass through the support portion 12a, and 15 a receiving pipe. An overflow pipe that connects the upper tank 7 and the lower tank 13 is a return pipe that communicates with a return path passing through the support portion 12b. Here, the lower tank 1
The receiving pipe 14, the overflow pipe 15, and the return pipe 16 are provided adjacent to the hoist 4.

Next, FIG. 2 shows an enlarged view of the main part of the pachinko island constructed as described above. As apparent from this figure, the support portions 12a and 12b are provided so as to protrude from both side surfaces of the upper tank 7. These support parts 12a, 12b
Is made of, for example, a metal box.
a, a later-described outgoing path 27 is passed through, and the other support portion 12b
Is passed through a return path 28 described later.

The upper tank 7 incorporates an inclined guide plate 17 having a downstream side connected to an upper portion of the support portion 12a as shown in the figure, and an upstream side shown in FIG. With the upper gate 4a of the machine 4 facing, the downstream side of the guide plate 17 is opened above the outward path 27. The pachinko balls pumped by the pump 4 by the guide plate 17 are distributed and supplied to the inside of the upper tank 7 and the upstream side of the outward path 27. Further, a gate 18 to which the upstream side of the supply path 8 is connected is opened at the lower side of the upper tank 7 so that the pachinko balls of the upper tank 7 can be supplied from the supply path 8 to each pachinko game console 2 through the gate. is there.

On the other hand, the lower tank 13 has a lower surface 13a.
Is inclined, and the inside is divided into three regions by a partition plate 19. The respective regions are arranged in the direction of inclination of the lower surface 13a, and form a front region 20, an intermediate region 21, and a rear region 22 in order from the downstream side of the lower surface 13a. In each of these areas, the lower side is communicated, and an outlet 23 is opened downstream of the lower surface 13a and below the front area 20. Here, one end of the return pipe 16 is connected to the front area 20 and the other end of the return pipe is connected to the lower part of the support portion 12b, so that the front area 20 and the return path 28 communicate with each other via the return pipe 16. I am trying to do it. Further, one end of the receiving pipe 14 is connected to the rear area 22 and the other end of the receiving pipe is connected to a lower portion of the support portion 12a, so that the rear area 22 and the outward path 28 communicate with each other through the receiving pipe 14. Like that. Further, the intermediate region 21 communicates with the upper tank 7 via the overflow pipe 15,
The upper end of the overflow pipe 15 is set at a position higher than the gate 18 of the upper tank 7. In addition, the receiving pipe 14
Includes a spare tank 24 installed above the rear area 22 so that a large amount of pachinko balls can be held therein.

The upper tank 7 is provided with a discharge port 25 communicating with the support portion 12b at a position (broken line L2) above the upper end (broken line L1) of the overflow pipe 15, so that the upper tank 7 extends over the overflow pipe 15. The pachinko balls accumulated in the support portion 12b can be discharged to the return path 28 passing through the support portion 12b through the discharge port 25. Therefore, it is possible to prevent the pachinko balls from accumulating in the upper tank 7 in excess of the allowable amount. It is desirable to be able to stop the hoisting machine 4.

Here, in the pachinko game arcade, a plurality of pachinko islands including the pachinko island configured as described above are shown in FIG.
Alternatively, they are installed in parallel as shown in FIG. In addition,
Although there is no limitation on the number of installations, FIG. 4 shows an example in which five pachinko islands are juxtaposed. As shown in FIG. 4, in this example, each of the pachinko islands 1A to 1E is divided into a set of three blocks, and the respective blocks are set as block islands BL1 and BL2, respectively.

The block islands BL1 and BL2 are respectively connected to the pachinko islands 1A to 1C and 1C to 1C which belong to the same block.
The forward tank 27 (27) that inclines the upper tank 7 of 1E in the opposite direction.
a, 27b) and the return route 28 (28a, 28b) to form a knitting, and pachinko islands 1A to 1C and 1C of the same block
Pachinko balls can be exchanged between ~ 1E. In one block island BL1, the pachinko island 1C to which one end on the upstream side of the outward route 27a is connected is a parent island, and the other pachinko islands 1A and 1B are pachinko islands 1C as parent islands.
Is a child island that receives pachinko balls through the outbound route 27a. In the other block island BL2, the outward route 27
The pachinko island 1E to which one end on the upstream side of b is connected is a parent island, and the other pachinko islands 1C and 1D are child islands which receive pachinko balls from the pachinko island 1E as the parent island through the outward route 27b.

Here, the pachinko island 1C, which is the parent island of one block island BL1, serves as a relay island and the other block island B
Incorporated in L2. That is, the pachinko island 1C is a parent island of one block island BL1 and the other block island B
It is a shared island that becomes a child island in L2, and the pachinko ball received as a child island from the pachinko island 1E of the block island BL2,
This time, it can be supplied to pachinko islands 1A and 1B belonging to the same block island BL1 as a parent island.

More specifically, Pachinko Island 1C as a parent island,
1E has a guide plate 17 shown in FIG. 2, and a part of pachinko balls (about 70% of the entirety) pumped by its own lifting machine 4 is pachinko islands as child islands through outbound routes 27a and 27b. 1A, 1B and 1C, 1D are supplied, but there is no guide plate 17 on those child islands (except for the pachinko island 1C), and pachinko balls supplied from the parent island are received from the outgoing routes 27a, 27b via the receiving pipe 14. And is introduced into the lower tank 13 of the island.

The pachinko island 1C, which also plays the role of a relay island, has a receiving pipe 14 and can incorporate pachinko balls therein, but the endmost parent having no function as a relay island. The island (Pachinko Island 1E) does not have the receiving pipe 14 but receives pachinko balls from the collecting tank 29 installed in the wall of the amusement arcade, and introduces the pachinko balls into its own upper tank 7 by the lifting machine 4.

A return pipe 16 shown in FIG. 2 is provided on the pachinko island 1C as a relay island, and a pachinko ball is introduced into its own lower tank 13 from one end on the downstream side of the return path 28a leading to the support portion 12b. However, other pachinko islands do not have the return pipe 16, or even if they do, the path is cut off so that pachinko balls cannot flow. It should be noted that return routes 28a and 28b are provided on pachinko islands other than the pachinko island 1C.
Only passes through the support portion 12b, so that even if there is the return pipe 16, it does not flow into it. That is, in one block island BL1, surplus pachinko balls are discharged from the upper tank 7 of the pachinko islands 1A and 1B as child islands through the discharge port 25 to the outward path 28a and reduced to the pachinko island 1C as the parent island. The pachinko island 1C discharges surplus pachinko balls from the discharge port 25 to the upstream side of the return path 28b connected to the upper tank 7, and returns this to the collecting tank to which the other end of the return path 28b is connected. Pachinko Island 1
In D and 1E, the discharge ports 25 can be communicated with the return path 28b to return the surplus balls to the collecting tank 29 on the return path 28b. However, since the return path 28b is expected to increase the flow rate of the pachinko balls, The pachinko islands 1D and 1E are extended over another return route 28c in parallel with the return route 28b, and surplus balls are returned to the collecting tank 29 on the return route 28c.

Here, a series of flows of the pachinko balls will be described. First, the pachinko balls in the collecting tank 29 are supplied from the passage 30 into the pachinko island 1E, and the pachinko balls are transported by the pachinko island lifting machine to the upper tank 7 thereof. Will be pumped up.
The pachinko balls that have been discharged are separated by the guide plate 17,
About 30% of the whole is introduced into the upper tank of the island, and about 70% is supplied to the upstream side of the outward path 27b. Outbound 27
The pachinko ball that has flowed into the upstream side of b reaches the pachinko island 1C of the same block to which the downstream end of the outward path 27b is connected via the pachinko island 1D, and flows down the outward path 27b to the pachinko island 1D in the process. About half of the pachinko balls to be made are supported by the support portion 12a from a drop port (not shown) formed in the outward path 27b.
, And is stored in the rear area 22 of the lower tank 13 via the receiving pipe 14. Similarly, in the pachinko island 1C, the remaining pachinko balls flow into the lower tank 13 from the downstream end of the outward path 27b and are stored in the rear area 22 thereof.

The pachinko balls flowing into the lower tank 13 are:
It flows out from the outlet 23 and flows into the introduction section 5 of the freighter, and is respectively lifted to its own upper tank 7 by the freighter 4. The pachinko island 1C as the parent island and relay island is similar to the pachinko island 1E, in that the pachinko balls discharged by the lifter are distributed to the upstream side of the outward path 27a, and the following pachinko island 1C is used.
B, 1A, and each pachinko island 1A ~
In 1E, the pachinko balls flowing into the upper tank 7 are gate 1
8 and flows out to the supply path 8 and is supplied to each pachinko game console 2 through the supply path. And each pachinko game table 2
Pachinko balls as out-balls ejected are collected from the collection path 3
Is collected on the downstream side, and is returned to the upper tank 7 by the lifting machine 4. The flow rate of pachinko balls supplied to the upper tank 7 by the lifting machine 4 is controlled by the gate 1
When the amount of pachinko balls flowing out of the upper tank 8 is exceeded, the amount of pachinko balls held in the upper tank 7 increases, but when the amount of pachinko balls exceeds a certain level, surplus pachinko balls are transferred to the lower tank 13 through the overflow pipe 15. Discharged,
When the holding amount further increases, excess pachinko balls are discharged to the return paths 28a, 28b, 28c from the discharge port 25 of the upper tank. Pachinko balls discharged from the pachinko island 1C return to the collecting tank 29 through the return path 28b, and pachinko balls discharged from the pachinko islands 1D and 1E return to the collecting tank 29 through the return path 28c. On the other hand, the pachinko balls discharged from the upper tanks 7 of the pachinko islands 1A and 1B return to the pachinko island 1C as the parent island through the return path 28a, and from the downstream end through the lower part of the support portion 12b to the return pipe 16 via the return pipe 16.
It flows into the lower tank 13 of C.

In the lower tank 13, pachinko balls are discharged preferentially from the front area 20 on the downstream side.
Therefore, in the block island BL1 having the pachinko island 1C as the parent island where pachinko balls are collected in the front area, the supply of the pachinko balls from the other block island BL2 is reduced as much as possible, and the pachinko balls are supplied on the block island BL1. The pachinko balls can be circulated, and in each of the pachinko islands 1A to 1E, the pachinko balls are discharged preferentially from the intermediate region 21 over the rear region 22. Therefore, the supply of pachinko balls from other pachinko islands is minimized and the pachinko balls are present on the island. Pachinko balls can be used repeatedly.

As described above, according to the circulation system of the present invention, the amount of pachinko balls held in each pachinko island can be adjusted without excess or deficiency. However, in order to prevent the shortage of pachinko balls, each block island BL1, The counter 9 shown in FIG. 1 is installed on at least one pachinko island of BL2. In addition, it is preferable to add counters to all pachinko islands because it is possible for the player to quickly return the acquired pachinko balls, but in order to eliminate the shortage of pachinko balls on each pachinko island, a counter is provided for each block island. It is enough to install one. Therefore, in this example, as shown in FIG. 4, the counters 9 are installed on the pachinko island 1B of the block island BL1 and the pachinko island 1D of the block island BL2.

[0032]

As is apparent from the above description, according to the present invention, a plurality of pachinko islands are divided into a set of a plurality of blocks, and the upper tank is connected on the outward path and the return path, each of which is inclined in the opposite direction. Block islands, and each pachinko island discharges surplus balls on the return route while receiving the shortage from other pachinko islands on the outbound route, so it is possible to adjust the amount of pachinko balls on each pachinko island without excess or shortage, and The pachinko balls circulated by the lifting machine are circulated by natural flow instead of the pachinko balls being diverted by the control device with the moving part, so the structure of the pachinko island is simplified and the pachinko balls are smoothly circulated. Can be. Further, when adding a pachinko island, for example, it is sufficient to connect the existing island and the upper tank on the outbound route and the return route, so that the installation work is very easy.

In particular, since each pachinko island has a lower tank provided below the upper tank and communicates with the overflow pipe, the amount of pachinko balls held in the upper tank can be limited, and further, the pachinko balls can be stored in the upper tank above the overflow pipe. A discharge port prevents clogging even when the amount of pachinko balls suddenly increases, and the lower tank communicates with the lower part of the lifting machine so that when the number of pachinko balls runs short in the upper tank, it is quick. Can be replenished.

The inside of the lower tank is divided into a plurality of rooms, and pachinko balls flowing from the upper tank through the overflow pipe flow out of the pachinko balls flowing from other islands through the receiving pipe to the lifting machine. As a result, pachinko balls are not excessively supplied from other pachinko islands on the outbound route, and surplus balls are used with priority given to surplus pachinko balls sent from other pachinko islands sent through return pipes. There is no place to go and it circulates smoothly.In addition, a guide plate is provided in the upper tank, and pachinko balls discharged by the lifting machine can be distributed to the outbound path and supplied to other pachinko islands, so that replenishment is smooth. .

Further, a counter is provided on the pachinko island in the block island, so that the pachinko balls obtained by the player can be returned to the inside thereof. Has the advantage that it can be easily returned.
