Connected to the provided The secondary pachinko island platform is connected to the overflow ball guiding path and the main pachinko ball is connected to the overflow ball guiding path. It is returned to the large storage tank through a second alternating current tank as the alternating current tank provided through the upper tank of the pachinko island stand, and the first and second alternating current tanks are arranged in the vertical direction. The large storage tank is connected to each downstream end of the first and second AC rods and receives a pachinko ball that has flowed down the first and second AC rods, and received by the receiving unit. And sequentially storing means for storing pachinko balls in a storage space inside the large storage tank according to a storage order inside the large storage tank.

  Moreover, in invention of Claim 2, in the island alternating current type | form ball transfer system of Claim 1, the said own island supply path, the said other island supply path, the said own island return path, and the said overflow ball guidance path are respectively The self-island recirculation route and the overflow ball guiding route are arranged adjacent to each other and formed in the upper tank.

  Moreover, in invention of Claim 3, in the island alternating current type | form ball transfer system of Claim 1 or Claim 2, the said 1st alternating current reed is arrange | positioned above the said 2nd alternating current reed, It is characterized by the above-mentioned. To do.

In the first aspect of the invention, the pachinko balls discharged from the ball discharge basket of the ball lifting device and stored in the upper tank are first supplied to the supply basket on the own island through the own island supply path. When the pachinko balls overflow in the own island supply route, the overflowing pachinko balls are supplied to the other islands through the other island supply route. Furthermore, when the pachinko ball overflows in the other island supply route, the overflowing pachinko ball is sent into the overflow passage of the own island through the own island return route. When the pachinko ball overflows in the self-island return route, the overflowing pachinko ball is guided toward the large storage tank via the overflow guide route. In addition to this basic structure of the upper tank, the self-island recirculation route is closed and the pachinko balls overflowing from the other island replenishment route are guided to the overflow guidance route. Are used as the upper tanks of the main pachinko islands that are arranged adjacent to the main pachinko islands. For this reason, the upper tank can be used in common between the main pachinko island base and the secondary pachinko island base with a slight change.
Further, in the configuration of the upper tank, a second AC pad for returning the pachinko balls from the sub-pachinko island stand to the large storage tank is provided through the upper tank of the main pachinko island stand, and the second AC pad A first AC pad that returns the pachinko balls from the main pachinko island stand to the large storage tank is arranged side by side in the vertical direction. On the other hand, the large storage tank is connected to the downstream ends of the first and second AC rods, and receives the pachinko balls that have flowed down the first and second AC rods. Sequential storage means for appropriately storing the pachinko balls in the storage space inside the large storage tank according to the storage order inside the large storage tank is provided. As a result, pachinko balls from the main pachinko island stand and pachinko balls from the sub-pachinko island stand can be individually returned to the large storage tank with separate AC poles, so the pachinko balls can be returned quickly. it can. However, the receiving means and the sequential storage means provided in the large storage tank can be used in common for each of the first and second AC tanks. That is, since it is not necessary to provide the receiving means and the sequential storage means for each of the first and second AC tanks, it is possible to reduce the number of parts constituting the large storage tank and to assemble the large storage tank. Can be facilitated.

  In the invention of claim 2, the self-island replenishment route, the other-island replenishment route, the self-island recirculation route, and the overflow ball guidance route are formed in the upper tank, respectively, Place the route next to each other. As a result, in the upper tank of the main pachinko island stand, it is possible to easily create a configuration that closes the self-island return route and guides the pachinko balls overflowing from the other island supply route to the overflow guide route. In the configuration used in common for the main pachinko island platform and the sub pachinko island platform, the change work to be performed on the upper tank is facilitated.

  Further, in the invention of claim 3, the first AC pad that returns the pachinko balls from the main pachinko island stand to the large storage tank, and the second AC pad that returns the pachinko balls from the sub pachinko island stand to the large storage tank. To place. At this time, in the upper tank of the main pachinko island stand, the pachinko balls overflowing from the other island replenishment route are directly guided to the overflow ball guiding route and returned to the large storage tank from the first alternating current rod. The pachinko balls always flowed down, and the weight of the first AC pad containing the pachinko balls is heavy. In addition, the length of the first AC rod is the same as the distance from the upper tank of the main pachinko island stand to the large storage tank and is short. On the other hand, in the upper tank of the sub-pachinko island stand, the pachinko balls overflowing from the other island replenishment route are guided to the self-island return route. Guide to the guide route and return to the large storage tank from the second AC pad. For this reason, it will be in the state where the pachinko ball occasionally flows down to the 2nd AC rod, and the weight of the 2nd AC rod containing the pachinko ball is light. The length of the second AC pad is the distance from the upper tank of the slave pachinko island to the large storage tank, that is, at least the main pachinko island that is interposed between the slave pachinko island and the large storage tank. The length that crosses the arrangement space is required to be long. Therefore, the first AC rod with a short length is difficult to be accelerated at the time of flow down, so the flow speed of the pachinko ball is slow, and the second AC rod with a long length is easy to be accelerated at the time of flow down. As a result, the second AC rod having a high flow velocity is arranged below the first AC rod having a low flow velocity. As a result, the pachinko balls that are always discharged from the upper side (first AC rod) into the receiving means are collided from above with the pachinko balls that are discharged from the lower side (second AC rod) into the receiving means. Therefore, it is possible to prevent the pachinko balls discharged from the lower side from colliding with the inner wall portion of the receiving means vigorously, and avoid damage to the receiving means due to the pachinko balls.

A ball feeding passage 62 is formed as a self-island replenishment route for feeding the balls to the pachinko machine 10 arranged on the ball discharge port 20b side of the ball feeding device 20 (the right side of the ball lifting device 20 shown in FIG. 2). Has been. At the lower end portion of the outer wall plate 31b, which is the downstream end of the ball feeding passage 62, a pachinko ball that has flowed down the ball feeding passage 62 is supplied to the ball discharge port 20b side (the right side of the ball feeding device 20 shown in FIG. 2). A lead-out port 63 leading to 21 is formed.

  A pachinko ball distributed on the ball distribution plate 61 is fed between one end (the end on the base tank B side) of the ball distribution plate 61 and the inner surface of the outer wall plate 31c of the upper tank 31. First and second guide plates 64 and 65 constituting a guide passage for guiding to the space 54 side are provided. The end portion of the second guide plate 65 that is the downstream end of the guide passage is disposed through the eaves installation space 52 and the lifting device installation space 53 so as to communicate the ball distribution space 51 and the ball feeding space 54. Connected to the upstream end of the connecting rod 66. On the other hand, the other side end portion (end portion on the non-base tank B side) of the ball distribution plate 61 is disposed in contact with the inner surface of the outer wall plate 31a of the upper tank 31, and a part of the ball distribution plate 61 includes a ball distribution plate. A drop port 67 is provided for dropping the pachinko ball on the plate 61 downward. Below the drop port 67, the upstream end (the other island supply route) of the AC rod 1a connected to the ball supply port 41 of the outer wall plate 31a is arranged. It is sent to 1a.

  Further, a pachinko ball overflowing on the ball sorting plate 61 is located upstream of the return basket 3 installed in the kite installation space 52 at a position directly below the ball discharge basket 20a that is disposed slightly protruding in the ball sorting space 51. A return passage 69 is formed as an overflow guide route for guiding to the part. A partition plate 70 is provided between the ball distribution plate 61, the first guide plate 64, the second guide plate 65, and the return passage 69. As a result, only the pachinko balls overflowing beyond the upper end of the partition plate 70 on the ball distribution plate 61 are guided to the return passage 69. Further, a discharge port 71 is provided at the downstream end of the return passage 69 to discharge the pachinko balls that have flowed down the return passage 62 to the upstream portion of the return basket 3 by communicating with the basket installation space 52.

  The ball feeding space 54 communicates with the downstream end of the connection rod 66 passed between the ball distribution space 51 (the end portion of the second guide plate 65) and the pachinko that has flowed down the connection rod 66. A ball feeding passage 72 as a self-island replenishment route for feeding the balls to the pachinko machine 10 arranged on the opposite side (the left side of the ball feeding device 20 shown in FIG. 2) to the ball discharge port 20b of the ball feeding device 20. Is formed. At the lower end portion of the outer wall plate 31d, which is the downstream end of the ball feed passage 72, the pachinko balls that have flowed down the ball feed passage 72 are on the side opposite to the ball discharge port 20b (left side of the ball lifting device 20 shown in FIG. 2). A lead-out port 73 leading to the replenishing rod 21 is formed.

  Thus, in the configuration of the upper tank 31 described above, the pachinko balls discharged from the ball discharge rod 20a of the ball lifting device 20 are fixed to the upper portion of the ball distribution space 51 in a horizontally inclined manner. Fall on top. Then, the pachinko balls that flow down on the ball distribution plate 61 due to the distribution of the ball distribution plate 61 are led out from the outlet 63 to the supply rod 21 through the ball feeding passage 62, and the pachinko on the ball discharge port 20b side. The machine 10 is replenished. Further, the pachinko balls sent to the guide passage (first and second guide plates 64, 65) side from the ball sorter plate 61 by the ball sorter plate 61, in other words, replenishment on the ball outlet 20b side. The pachinko balls that are fed to the guide passage side when the basket 21 is full flow to the ball feed passage 72 of the ball feed space 54 through the connection rod 66 and are then led out to the replenishment bowl 21 from the outlet 73. The pachinko machine 10 on the side opposite to the discharge port 20b is replenished. Further, the pachinko balls dropped downward from the drop port 67 formed in the ball distribution plate 61 by the distribution of the ball distribution plate 61 are sent to the upstream end of the AC rod 1a, and the upper tank 32 of the pachinko island stand A2. Will be replenished. Further, the pachinko balls overflowing beyond the upper end of the partition plate 71 on the ball distribution plate 61 are sent to the return basket 3 from the discharge port 71 through the return passage 69 and returned to the base tank B.

  As described above, the pachinko balls polished and lifted by the ball lifting device 20 are first distributed so as to be preferentially replenished to the replenishment rod 21 of the own island. In addition, on the structure of the upper tank 31, as described above, the structure is such that one replenishing rod 21 is filled after the other replenishing rod 21 is full. Since the amount of lift per hour is much larger than the average amount of balls consumed through one supply rod 21, pachinko balls are always being supplied to both supply rods 21.

  Although the configuration of the pachinko island platform A1 has been described above, the upper tank 31 provided on the pachinko island platform A1 guides pachinko balls to each pachinko machine 10 on its own island with the highest priority, and the guidance is no longer necessary. Sometimes it is guided to the pachinko island platform A2 via the AC rod 1a and further guided to the base tank B via the return rod 3 when the guidance is no longer necessary. Thereby, the replenishment of the pachinko ball to the own island and the supply of the pachinko ball to the pachinko island platform A2 can be performed smoothly.

  Next, regarding the pachinko island platform not adjacent to the base tank B and the upper tank provided on the pachinko island platform, an example of the pachinko island platform A3 and the upper tank 33 of the pachinko island platform A3 will be described with reference to FIGS. I will explain. The pachinko island platform not adjacent to the base tank B is not different from the pachinko island platform A1 in the basic configuration as shown in FIG. 8, and the difference is that the structure of the upper tank is built in the own island. Overflow from the structure of the lower storage tank 13 (as described above, the inlet 18 to which the inlet 4 is connected only to the lower storage tank 13 of the pachinko island stand A1 adjacent to the base tank B) and the upper tank A structure for guiding the pachinko balls supplied from the pachinko balls and the alternating current basket to the lower storage tank 13, and the like. Hereinafter, the pachinko island platform A3 and the upper tank 33 of the pachinko island platform A3 will be described focusing on these differences.

  In FIG. 8, a pachinko island platform A3 as a sub pachinko island platform is similar to the pachinko island platform A1 described above, and a lower storage tank 13 is built in, and a pachinko ball stored in the lower storage tank 13 is set substantially at the center. The ball is fed to the upper tank 33 by the ball lifting device 20 provided, and the balls are replenished to the pachinko machine 10 and the ball lending machine 19 installed on the pachinko island platform A3 via the replenishment rod 21. The pachinko balls used in the pachinko machine 10 are discharged to the out ball collection basket 12 through the out ball box 11, collected in the out ball collection basket 12, guided to the lower storage tank 13, and then dipped again. It is lifted by the device 20. As a result, the pachinko balls circulate in the pachinko island platform A3. Unlike the pachinko island platform A1 adjacent to the base tank B, an overflow passage 22 is provided in the pachinko island platform A3 not adjacent to the base tank B.

  The overflow passage 22 is linearly fixed inside one side of the space where the ball feeding device 20 is installed, and has a predetermined thickness (for example, 1 to 2 cm) in the illustrated embodiment. In order to weaken the momentum of the pachinko balls that are formed in a square tube shape (may be formed in a square tube shape with a metal plate) with wood such as a veneer plate, a large number of alternating current plates 23 are protruded alternately. ing. A rubber plate or a synthetic resin plate is attached to the upper surface of the AC plate 23 and the inner peripheral surface of the overflow passage 22 in order to suppress noise generated by the fall of the pachinko balls. A guide path 24 communicating with the above-described upper guide rod 15 provided in the lower storage tank 13 is connected to the downstream end of the overflow path 22, and the pachinko balls that have fallen in the overflow path 22 are guided by the guide path 24. It passes through the lower storage tank 13. On the other hand, the upstream end of the overflow passage 22 is disposed in communication with an overflow rod 120 described later provided in the upper tank 33.

  The upper tank 33 provided on the pachinko island stand A3 has a function of distributing the received pachinko balls to the replenishment basket 21 or the alternating current baskets 1d and 1e. Hereinafter, the structure of the upper tank 33 provided in the pachinko island stand A3 will be described. The upper tank 33 is formed in a cubic shape by outer wall plates 33a to 33d. As shown in FIG. 9, an opening / closing door 80 for maintenance and inspection is provided on one side surface (outer wall plate 33a) of the upper tank 33 on the non-base tank B side, and pachinko balls in the upper tank 33 are attached to the pachinko island. A ball replenishing port 81 to which an AC rod 1e for replenishing the upper tank 34 of the table A4 is connected, and an AC rod 1f for receiving the pachinko balls overflowing from the upper tank 34 of the pachinko island platform A4 into the upper tank 33 are provided. A ball receiving port 82 to be connected is formed. On the other hand, on the other side surface (outer wall plate 33c) of the upper tank 33 on the base tank B side, as shown in FIG. 10, there is an AC rod 1d for returning pachinko balls overflowing from the upper tank 33 to the base tank B. A ball return port 83 to be connected and a ball receiving port 84 to which an AC rod 1c for receiving a pachinko ball overflowing from the upper tank 32 of the pachinko island stand A2 is received in the upper tank 33 are formed. .

  Further, as shown in FIGS. 11 to 14, the inside of the upper tank 33 is viewed from the non-base tank B side (from the front of FIG. 11) in the order from left to right as in the upper tank 31. The ball distribution space 91 for distributing the pachinko balls lifted by the ball lifting device 20, the cage installation space 92 in which the upstream portion of the AC cage 1d and the downstream portion of the AC cage 1f are installed, and the ball lifting device 20 And the ball discharge port 20b of the ball lifting device 20 installed in the lifting device installation space 91 on the opposite side (the left side of the ball lifting device 20 shown in FIG. 8). And a ball feeding space 94 for feeding pachinko balls to the pachinko machines 10 arranged in a row. The ball discharge rod 20a of the ball lifting device 20 installed in the lifting device installation space 93 is located in the upper region of the basket installation space 92 so as to communicate the lifting device installation space 93 and the ball distribution space 91. It is arranged to pass through.

  In the ball distribution space 91, as shown in FIG. 15, a ball distribution plate 101 is fixed in a horizontally inclined manner at a lower position on the downstream end side of the ball discharge rod 20a. The ball distribution plate 101 is disposed so as to be slightly inclined downward from the basket installation space 92 side to the ball distribution space 91 side, and below the downstream end thereof, the pachinko that has flowed down on the ball distribution plate 101 is disposed. A ball feeding passage 102 is formed as a self-island replenishment route for feeding the balls to the pachinko machine 10 arranged on the ball discharge port 20b side of the ball feeding device 20 (the right side of the ball lifting device 20 shown in FIG. 8). Has been. At the lower end portion of the outer wall plate 33b, which is the downstream end of the ball feed passage 102, a replenishment rod for the pachinko ball that has flowed down the ball feed passage 102 on the ball discharge port 20b side (the right side of the ball feeding device 20 shown in FIG. 8). A lead-out port 103 leading to 21 is formed.

  A pachinko ball distributed on the ball distribution plate 101 is fed between one end of the ball distribution plate 101 (end on the base tank B side) and the inner surface of the outer wall plate 33c of the upper tank 33. First and second guide plates 104 and 105 constituting a guide passage for guiding to the space 94 side are provided. The end portion of the second guide plate 105 which is the downstream end of the guide passage is disposed through the eaves installation space 92 and the lifting device installation space 93 so as to communicate the ball distribution space 91 and the ball feeding space 94. Connected to the upstream end of the connecting rod 106. On the other hand, the other side end portion (end portion on the non-base tank B side) of the ball distribution plate 101 is disposed in contact with the inner surface of the outer wall plate 33a of the upper tank 33. A drop port 107 is provided for dropping the pachinko ball on the plate 101 downward. Below the drop port 107, an upstream end of the AC basket 1e connected to the ball replenishment port 81 of the outer wall plate 33a is arranged so that the pachinko balls dropped from the drop port 107 are fed into the AC bowl 1e. It has become.

  In addition, an overflow cage 120 (for guiding the pachinko balls overflowing on the ball sorting plate 101 to the overflow passage 22 is located directly below the ball ejection cage 20a that is disposed slightly protruding in the ball sorting space 91. A ball feed passage 109 is formed as a self-island recirculation route for feeding into the confluence induction rod). The overflow rod 120 is disposed in contact with the inner surface of the outer wall plate 33c, and is disposed so as to incline downward from the ball distribution space 91 through the rod installation space 92 toward the lifting device installation space 93, The downstream end of the overflow rod 120 is disposed at the lower end position of the lifting device installation space 93 and is provided in communication with the overflow passage 22. A partition plate 110 is provided between the ball distribution plate 101, the first guide plate 104, the second guide plate 105, and the ball feed passage 109. As a result, only pachinko balls overflowing beyond the upper end of the partition plate 110 on the ball distribution plate 101 are guided to the ball feed passage 109. Further, the downstream end of the ball feed passage 109 is provided so as to communicate with the midstream portion of the overflow rod 120.

  In addition, a communication port 112 that connects the ball distribution space 91 and the basket installation space 92 is formed in an upstream portion of the ball feeding passage 109 in the partition plate 111 that divides the ball distribution space 91 and the basket installation space 92. It is installed. When the pachinko balls are filled in the overflow passage 22 (overflow rod 120) and the pachinko balls are stacked in the ball feed passage 109, the communication port 112 is used to place the pachinko balls in the ball feed passage 109 into the bowl installation space 92. The pachinko ball which is an opening for feeding to the side and is sent to the coffin installation space 92 through the communication port 112, in other words, the pachinko ball overflowing from the ball distribution space 91 to the coffin installation space 92 side, It is discharged to the upstream part of the AC wall 1d installed in the space 92.

  Further, in the ball distribution space 91 of the upper tank 33, unlike the ball distribution space 61 of the upper tank 31 described above, the ball receiver of the outer wall plate 33c is located below the position where the upstream end of the AC rod 1e is disposed. A ball rolling plate 113 is provided for receiving pachinko balls discharged from the AC rod 1 c connected to the inlet 84 and rolling the pachinko balls to the upstream side of the overflow rod 120. Further, in the cage installation space 92, a ball rolling plate 114 that receives the pachinko ball discharged from the AC cage 1f connected to the ball receiving port 82 of the outer wall plate 33a and rolls it to the downstream side of the overflow cage 120. Is provided. As a result, as shown in FIG. 16, the pachinko balls fed into the upper tank 33 from the AC rod 1 c (pachinko island platform A 2) flow into the upstream portion of the overflow rod 120 via the ball rolling plate 113. The pachinko balls overflowing beyond the upper end of the partition plate 110 on the above-described ball distribution plate 101 flow into the midstream portion of the overflow rod 120 through the ball feed passage 109, and the AC rod 1f (pachinko island platform A4). The pachinko balls fed into the upper tank 33 flow into the downstream portion of the overflow rod 120 via the ball rolling plate 114, and these pachinko balls are merged on the overflow rod 120 and fed into the overflow passage 22. It is like that.

  The ball feeding space 94 communicates with the downstream end of the connection rod 106 passed between the ball distribution space 91 (the end portion of the second guide plate 105) and the pachinko that has flowed down the connection rod 106. Ball feed passage 115 as a self-island replenishment route for feeding the balls to the pachinko machine 10 arranged on the opposite side of the ball discharge port 20b of the ball feed device 20 (left side of the ball lift device 20 shown in FIG. 8). Is formed. At the lower end portion of the outer wall plate 33d, which is the downstream end of the ball feeding passage 115, the pachinko balls that have flowed down the ball feeding passage 115 are on the side opposite to the ball discharge port 20b (the left side of the ball feeding device 20 shown in FIG. 8). A lead-out port 116 leading to the replenishing rod 21 is formed.

  Thus, in the configuration of the upper tank 33 described above, the pachinko balls discharged from the ball discharge rod 20a of the ball lifting device 20 are fixed to the upper portion of the ball distribution space 91 in a horizontally inclined shape. Fall on top. Then, the pachinko balls that flow down on the ball distribution plate 101 by the distribution of the ball distribution plate 101 are led out from the outlet 103 to the supply rod 21 through the ball feed passage 102, and the pachinko ball on the ball discharge port 20b side. The machine 10 is replenished. In addition, the pachinko balls sent to the guide passage (first and second guide plates 104, 105) side from the ball sorter plate 101 by the ball sorter plate 101, in other words, replenishment on the ball outlet 20b side. The pachinko balls that are fed into the guide passage side when the basket 21 is full flow to the ball feed path 115 of the ball feed space 94 through the connection rod 106 and then are led out from the outlet 116 to the replenishment bowl 21 to be The pachinko machine 10 on the side opposite to the discharge port 20b is replenished. Further, the pachinko balls dropped downward from the drop port 107 formed in the ball sorting plate 101 by sorting the ball sorting plate 101 are sent to the AC bowl 1e and supplied to the upper tank 34 of the pachinko island platform A4. The

  Further, the pachinko balls sent from the pachinko island platform A2 through the alternating current basket 1c into the upper tank 33 are guided to the upstream portion of the overflow basket 120 through the ball rolling plate 113. Pachinko balls overflowing beyond the upper end of the partition plate 110 on the ball distribution plate 101 are guided to the midstream side portion of the overflow basket 120 through the ball feed passage 109. The pachinko balls sent from the pachinko island platform A4 through the AC rod 1f into the upper tank 33 are guided to the downstream side portion of the overflow rod 120 via the ball rolling plate 114. Then, these pachinko balls are merged on the overflow basket 120 and fed into the overflow passage 22. Further, the pachinko balls filled with the overflow passage 22 (overflow rod 120) and overflowing from the ball distribution space 91 (ball feed passage 109) side to the rod installation space 92 side are installed in the rod installation space 92. It is sent to the upstream part of the AC wall 1d and returned to the base tank B.

  As described above, the pachinko balls polished and lifted by the ball lifting device 20 are first distributed so as to be preferentially replenished to the replenishment rod 21 of the own island. In addition, the structure of the upper tank 33 has a structure in which one of the replenishing rods 21 is filled as described above, and the other replenishing rod 21 is replenished. Since the amount of lift per hour is much larger than the average amount of balls consumed through one supply rod 21, pachinko balls are always being supplied to both supply rods 21.

  By the way, in the upper tank 33 of the pachinko island platform A3 that is not adjacent to the base tank B described above, the pachinko balls are supplied to the replenishment rod 21 on the own island at the position farthest from the ball discharge rod 20a of the ball lifting device 20. The ball feed passages 102 and 115 that serve as own island supply paths are arranged, and the upstream end of the AC fence 1e that serves as another island supply path for supplying pachinko balls to other islands at the next distant position, and other islands on other islands A ball rolling plate 113 serving as a first receiving path for receiving pachinko balls supplied from the replenishment path is disposed, and then the pachinko balls overflowing from the other island replenishment path are placed in the overflow path 22 of the own island at a position away from the next. A ball feed passage 109 serving as a return route for the own island is arranged, and the overflow that guides the pachinko balls overflowed by the return route of the own island toward the base tank B, closest to the ball discharge rod 20a of the ball lifting device 20 With ball guidance path And the upstream end of the AC gutter 1d that are arranged and Ball Utatedoban 114 serving as the second receiving path for receiving a pachinko balls derived from 溢玉 guide route other island. Thereby, as a basic structure, it is only necessary to provide a ball guide plate (ball distribution plate 101 or the like) inclined downward toward the direction away from the ball discharge rod 20a of the ball lifting device 20. The discharge ball guiding structure for guiding the pachinko balls discharged from the ball lifting device 20 in the upper tank 33 can be simplified.

  Further, in a normal state in which the own island replenishment route (ball feeding passages 102 and 115) is full of pachinko balls and the other island replenishment route (AC 1e) is almost full of pachinko balls, the ball lifting device 20 The pachinko balls discharged from the ball collide with the pachinko balls stacked on the ball distribution plate 101 without colliding with members constituting the inside of the upper tank 33 (hereinafter also referred to as internal component members). Then, it is sent to the own island return route (ball feed passage 109) as it is. For this reason, the malfunction that the internal structural member of the upper tank 33 is damaged by the impact of the pachinko ball discharged from the ball lifting device 20 can be avoided.

  Further, since the overflowing pachinko balls are sent to other spaces, the self-island replenishment route (ball feeding passages 102 and 115) that does not require a large height space is farthest from the ball discharge rod 20a of the ball lifting device 20 In other words, the entire upper tank 33 can be made compact because it is arranged at the position where it becomes the downstream end of the ball guide plate (ball distribution plate 101, etc.) and the height dimension cannot be widened.

  In addition, the self-island replenishment route (ball feed passages 102 and 115), the other island replenishment route (AC wall 1e), the first receiving route (ball rolling plate 113), the self-island recirculation route (ball feed passage 109) as described above. ), According to the arrangement configuration in order of the overflow ball guiding path (AC rod 1d) and the second receiving path (ball rolling plate 114), a plurality of pachinko island platforms A1 to A4 and a base tank B serving as a large storage tank In the island exchange group composed of the ball transfer paths (AC fences 1a to 1f and return fence 3) installed between the pachinko islands A1 to A4 and the base tank B, as viewed from above (FIG. 1A). The line of pachinko balls between the pachinko islands A1 to A4 and the base tank B can be quickly transferred.

  Further, in the configuration of the upper tank 33, the pachinko balls received from the first receiving path (ball rolling plate 113) and the second receiving path (ball rolling plate 114) and the own island return path (ball feeding path 109). The pachinko balls received from the above are joined together by the overflow basket 120 in the upper tank 33 and sent to the lower storage tank 13 through the overflow passage 22. For this reason, between the upper tank 33 and the lower storage tank 13, in other words, in the height space where the pachinko machine 10 is installed in the pachinko island platform A3, the upper tank 33 is not provided with a confluence of pachinko balls. Since it is only necessary to provide the overflow passage 22 for guiding the overflowing pachinko balls to the lower storage tank 13, the space can be used effectively. In addition, the height space where the pachinko machine 10 is installed is a space where the pachinko machine 10 originally arranges various devices and equipment such as a wiring / banknote transport device related to the pachinko machine 10, and in the past, the space has been secured. It was difficult.

  In addition, the self-island replenishment route (ball feed passages 102 and 115), the other island replenishment route (AC wall 1e), the first receiving route (ball rolling plate 113), the self-island recirculation route (ball feed passage 109) as described above. ), In the arrangement configuration in the order of the overflow ball guiding path (AC 1d) and the second receiving path (ball rolling plate 114), as a structure for joining the pachinko balls with the overflow rod 120, from the downstream side of the overflow rod 120 The upstream order, in other words, the priority of merging is determined according to the arrangement order of the various routes, the second receiving path (ball rolling plate 114), the self-island return path (ball feeding path 109), the first receiving path ( The order of the ball rolling plate 113). For this reason, when the three types of pachinko balls are merged in the upper tank 33 (overflow rod 120), it is not necessary to provide a special ball guiding path, and the pachinko balls can be reliably merged with a simple structure. .

  As described above, the upper tank 31 of the pachinko island platform A1 adjacent to the base tank B includes the own island supply route, the other island supply route, and the overflow guidance route, while the own island return route, the first receipt The route and the second receiving route are not provided. That is, since the pachinko island platform A1 is an island platform that is adjacent to the base tank B and receives the supply of pachinko balls directly from the base tank B, the pachinko island platform A1 is supplied from the other island supply path of other islands (pachinko island platforms A2 to A4). There is no need to provide a first receiving path for receiving the pachinko balls. In addition, if the overflow guidance route on the other island reaches the pachinko island stand A1, the pachinko ball from the overflow guidance route on the other island can be directly guided to the base tank B. There is no need to provide a second receiving path on the pachinko island platform A1 that accepts pachinko balls derived from the path.

  On the other hand, among the pachinko islands not adjacent to the base tank B, pachinko balls A2 and A4 other than the pachinko islands A3 are used to return the pachinko balls acquired by the player to the lower storage tank 13, respectively. A ball return device 5 is installed. That is, the pachinko islands A2 and A4 form a return pachinko island on which the ball return device 5 is installed, and the pachinko island stand A3 forms a non-return pachinko island on which the ball return device 5 is not installed. Although not shown, the upper tank 32 of the pachinko island platform A2 includes a self-island replenishment route, a separate island replenishment route, a self-island recirculation route, an overflow ball guidance route, and a first receipt route, while a second receipt route. Not equipped. That is, the pachinko island stand A2 is a return pachinko island stand, and there is a high possibility that a large amount of pachinko balls are returned from the ball return device 5 and the pachinko balls in the island stand are excessively increased. For this reason, if the second receiving path is provided, the pachinko balls received from the second receiving path flow into the overflow ball guiding path, and as a result, the overflow ball guiding path increases due to the return from the ball returning device 5. It is because it becomes impossible to correspond to the pachinko ball.

  Although not shown, the upper tank 34 of the pachinko island stand A4 includes a self-island replenishment route, a self-island recirculation route, an overflow ball guidance route, and a first receiving route, while the other island replenishing route and the second receiving route are provided. Not equipped. That is, since the pachinko island stand A4 is an island stand located at the end of the island stand block, the pachinko is derived from the other island supply route for supplying the pachinko balls to other islands and the overflow guide route of the other islands. There is no need to provide a second receiving path for receiving balls.

  By the way, as a structure of the upper tank 31 provided in the pachinko island stand A1 adjacent to the base tank B, as described above, the upstream part of the return basket 3 as the first AC pad is installed and the second AC pad is used. Of the AC rod 1b and the AC rod 1d are provided, and the return rod 3 and the AC rods 1b and 1d are connected to the base tank B at their downstream ends. Yes. Hereinafter, the return rod 3 and the AC rods 1b and 1d provided between the upper tank 31 and the base tank B of the pachinko island platform A1 are connected to the downstream ends of the return rod 3 and the AC rods 1b and 1d. The base tank B will be described with reference to FIGS. FIG. 17 is a perspective view showing a state in which the upper tank 31 of the pachinko island platform A1 provided adjacent to the base tank B and the base tank B are connected via the return rod 3 and the AC rods 1b and 1d. FIG. 18 is a partially enlarged perspective view showing a connection portion of the return rod 3 and the AC rods 1b and 1d that connect the upper tank 31 and the base tank B of the pachinko island base A1 provided adjacent to the base tank B. FIG.

  As shown in FIG. 17, between the upper tank 31 and the base tank B of the pachinko island platform A1, the return rod 3 and the AC rods 1b and 1d are installed in a state of being arranged in the vertical direction. On the other hand, the base tank B is formed in a rectangular parallelepiped shape whose upper surface is opened by a plywood (may be a metal plate), and the priority tank part 131 and the non-priority tank part 132 in which the storage order in which pachinko balls are stored is determined. And a dispersion mechanism 133 that disperses pachinko balls returned to the base tank B and located above the priority tank part 131 and the non-priority tank part 132.

  The dispersion mechanism 133 is a return branch box 134 as a receiving means disposed and fixed substantially at the upper center of the base tank B, and a sequential storage means that is inclined downward from the return branch box 134 toward the priority tank section 131 side. Return ball priority dispersion basket 135 and return ball non-priority dispersion basket 136 as a sequential storage means inclined downward from the return branch box 134 toward the non-priority tank unit 132 side. Note that guide plates 137 are provided on both sides of the upstream end of the return ball priority dispersion basket 135. The guide plate 137 has a function of reliably guiding the pachinko balls to the priority tank portion 131 and facilitating the flow of the pachinko balls to the downstream end of the priority tank portion 131. Further, since the pachinko balls do not fall from the portion where the guide plate 137 is provided, the guide plate 137 is located below the guide plate 137, that is, adjacent to the non-priority tank portion 132 and downstream of the priority tank portion 131. It also has a function of not depositing pachinko balls that fall directly from the return ball priority dispersion basket 135 in the vicinity.

  As shown in FIG. 18, the return branch box 134 is formed in a rectangular parallelepiped shape whose upper surface is opened by a plywood (or a metal plate), and a priority port 138 is provided below the surface on the priority tank unit 131 side. And a non-priority port 139 is formed on the non-priority tank 132 side and slightly above the priority port 138. The priority port 138 communicates with the upstream end of the return ball priority dispersion basket 135, and the non-priority port 139 communicates with the upstream end of the return ball non-priority dispersion basket 136. Further, the bottom surface of the return branch box 134 is a guide bottom surface 140 inclined downward from the non-priority port 139 toward the priority port 138, and is located at the upstream end of the guide bottom surface 140 and below the non-priority port 139. The damming member 141 is fixed so that the pachinko balls falling on the guide bottom surface 140 are not easily guided to the non-priority port 139. Further, inclined guiding members 142 and 143 are provided on the side of the guiding bottom surface 140. Furthermore, a connection port 144 to which the downstream end of the return basket 3 is connected, a downstream end of the AC fence 1b, and a downstream end of the AC fence 1d are located above the surface of the return branch box 134 where the tilt guiding member 142 is provided. Connection ports 145 connected together are formed side by side in the vertical direction. In addition, the downstream end of the return rod 3, the downstream end of the AC rod 1b, and the downstream end of the AC rod 1d are provided together, and the lower surface of the return rod 3 is brought into contact with the upper surface of the AC rod 1b. You may make it connect in a state. By doing in this way, since the weight of the return basket 3 which always returns the pachinko ball can be supported by a plurality of baskets, the bottom surface of the return basket 3 bends due to the weight, and the ball flow of the pachinko balls Troubles such as troubles can be solved.

  Thus, the pachinko balls that have overflowed in the upper tank 31 of the pachinko island platform A1 and have flowed down the return basket 3 are discharged from the connection port 144 into the return branch box 134 of the base tank B. In addition, the pachinko ball that flowed down the AC basket 1b through the upper tank 31 from the upper tank 32 of the pachinko island platform A2, and the AC kite 1d through the upper tank 31 from the upper tank 33 of the pachinko island platform A3. The pachinko balls are discharged from the connection port 145 into the return branch box 134 of the base tank B, respectively.

  Then, the pachinko balls discharged from the return basket 3 and the AC boxes 1b and 1d into the return branch box 134 fall on the guide bottom surface 140 in the return branch box 134, and return ball priority dispersion baskets from the priority port 138. It flows down 135 and is sent into the priority tank 131. Thereafter, as the pachinko balls are fed into the priority tank unit 131, the pachinko balls are stored from the upstream side of the priority tank unit 131, and the pachinko balls are continuously fed into the priority tank unit 131 so that the return ball priority dispersion basket 135 is over. When the pachinko balls stay in the return branch box 134, the pachinko balls discharged into the return branch box 134 flow down from the non-priority port 139 onto the return ball non-priority dispersion basket 136 and are sent into the priority tank 131.

  In the above-described embodiment, as a configuration of the upper tank 31 provided in the pachinko island platform A1 adjacent to the base tank B, the return path 69 as an overflow guiding path is formed by closing the own island return path, The return passage 69 and the installation space for the return basket 3 (the installation space 52) are provided adjacent to each other in the upper tank 31. However, the present invention is not limited to this configuration. It is good also as a structure provided in an upper tank so that it may not adjoin. Hereinafter, such a configuration will be described as a modification with reference to FIGS. 19 to 21. FIG. FIG. 19A is a top view showing the flow of pachinko balls in the upper tank 150 in the modified example, and FIG. 19B is a longitudinal sectional view showing the flow of pachinko balls in the upper tank 150 in the modified example. It is. FIG. 20A is a top view showing the flow of pachinko balls in the upper tank 150 in the modified example, and FIG. 20B is a longitudinal sectional view showing the flow of pachinko balls in the upper tank 150 in the modified example. It is. FIG. 21A is a top view showing the flow of pachinko balls in the upper tank 150 in the modified example, and FIG. 21B is a longitudinal sectional view showing the flow of pachinko balls in the upper tank 150 in the modified example. It is. Moreover, in the following description, about the structure which has a function similar to the above-mentioned embodiment, the same code | symbol is attached for convenience and the detailed description is abbreviate | omitted.

  As shown in FIGS. 19 (A) and 19 (B), the upper tank 150 of the modified example is returned from the right side to the left side when viewed from the base tank B side (viewed from the front in FIG. 19 (B)). 3 upstream part is installed and the downstream part of the alternating current cage 1b and the downstream part of the alternating current cage 1d are penetrated, and the ball distribution space 152 that distributes the pachinko balls fed by the ball lifting device 20 And the lifting device installation space 153 through which the upper portion of the ball lifting device 20 is installed, and the ball discharge rod 20a (ball discharge port 20b) of the ball lifting device 20 installed in the lifting device installation space 153. A ball feeding space 154 for feeding pachinko balls to the pachinko machines 10 arranged on the side is partitioned. The ball discharge rod 20a of the ball lifting device 20 installed in the lifting device installation space 153 is installed by connecting the lifting device installation space 153 and the ball distribution space 152, and the ball discharge port 20b is provided. It is arranged in the ball distribution space 152.

  In the ball distribution space 152, a ball distribution plate 155 is fixedly provided at a position below the ball discharge port 20b. The pachinko balls distributed on the ball distribution plate 155 are arranged on one side end (the end on the base tank B side) of the ball distribution plate 155 on the ball discharge port 20b side of the ball lifting device 20. A ball feed passage 156 for feeding into the pachinko machine 10 is formed. At the downstream end of the ball feed passage 156, a lead-out port (not shown) for leading the pachinko balls that have flowed down the ball feed passage 156 to the replenishment rod 21 on the ball discharge port 20b side is provided. On the other hand, a guide passage 157 for guiding the pachinko balls distributed on the ball distribution plate 155 to the ball feeding space 154 side is provided at the other end (end on the non-base tank B side) of the ball distribution plate 155. Is formed. The guide passage 157 is provided through the lifting device installation space 153 so as to communicate the ball distribution space 152 and the ball feeding space 154.

  In addition, a guide plate 158 that is inclined downward toward the lifting device installation space 153 is provided at the end of the upper end position of the ball feeding passage 156 on the lifting device installation space 153 side. The upstream end of the AC rod 1a is disposed below As a result, the pachinko balls overflowing from the ball feed passage 156 are fed into the AC rod 1a through the guide plate 158. Further, a ball receiving port 159 is formed between the ball distribution plate 155 and the space where the upstream end of the AC rod 1a is installed. The ball receiving port 159 has a downstream side from the AC rod 1a. A return passage 160 for sending the overflowing pachinko balls to the upstream end of the return basket 3 installed in the basket installation space 151 is provided in communication.

  The ball feeding space 154 communicates with the downstream end of the guide passage 157 passed between the ball distribution space 152 and the pachinko balls that have flowed down the guide passage 157 into the ball outlet of the ball feeding device 20. A ball feed passage 161 for feeding into the pachinko machine 10 arranged on the opposite side to 20b is formed. At the downstream end of the ball feed passage 161, there is provided a lead-out port (not shown) for leading the pachinko balls that have flowed down the ball feed passage 161 to the replenishment rod 21 on the side opposite to the ball discharge port 20b.

  Thus, in the configuration of the upper tank 150 described above, the pachinko balls discharged from the ball discharge rod 20a of the ball lifting device 20 are on the ball distribution plate 155 fixed to the upper portion of the ball distribution space 152 (FIG. 19). To point P in FIG. 21). Then, the pachinko balls fed into the ball feed passage 156 as the self-island replenishment route by the distribution of the ball distribution plate 155 flow down the ball feed passage 156 and are led out to the replenishment basket 21, so that the ball discharge port It is supplied to the pachinko machine 10 on the 20b side. In addition, the pachinko balls that have been fed from the guide passage 157 to the ball feed passage 161 as the self-island replenishment route by sorting the ball sorting plate 155 flow down the ball feed passage 161 and are led to the replenishment rod 21. The pachinko machine 10 on the side opposite to the ball outlet 20b is replenished. Also, as shown in FIGS. 20A and 20B, the replenishment of the pachinko balls to the replenishment basket 21 is full (in the same figure, the full portion of the pachinko balls is indicated by a hatched area) When a pachinko ball overflows from the feed passage 156, the pachinko ball overflowing from the ball feed passage 156 passes through the guide plate 158 and is sent to the upstream end of the AC rod 1a as the other island supply route. Furthermore, as shown in FIGS. 21A and 21B, the pachinko balls are filled with the alternating current basket 1a (in the figure, the full portion of the pachinko balls is indicated by a hatched area), and the alternating current basket 1a When the pachinko ball overflows from the upstream end, the pachinko ball overflowing from the upstream end of the AC rod 1a flows down from the ball receiving port 159 through the return passage 160 as the overflow ball guiding path to the upstream end of the return rod 3 It is sent in and returned to the base tank B through the return basket 3.

  Moreover, according to the structure of the upper tank 150 in the modification demonstrated above, the return channel | path 160 as an overflow ball guidance path | route is provided in the downstream of the ball receiving port 159 which receives the pachinko ball overflowing from the upstream end of the alternating current basket 1a. However, a bottom wall plate 162 constituting the passage bottom surface of the return passage 160 is provided vertically below the ball receiving port 159. The bottom wall plate 162 is removed from the upper tank 150 when the upper tank 150 is used in the pachinko islands A2 to A4 that are not adjacent to the base tank B. An overflow passage is provided as a reflux path. In other words, by adopting the upper tank 150 in the pachinko island platform A1 adjacent to the base tank B, the bottom wall plate 162 is attached in the upper tank 150 and the own island return path is closed. Thereby, in the modification, it is the structure which provides in the upper tank 150 so that the closed self-island reflux path | route (space where the bottom wall board 162 was attached) and the return basket 3 may not be adjacent.

  As described above, according to the configuration of the present embodiment, the pachinko balls that are discharged from the ball discharge basket 20a of the ball feeding device 20 and stored in the upper tank 33 are first self-supplied through the self-island supply route. Supplied to the island supply tank 21. When the pachinko balls overflow in the own island supply route, the overflowing pachinko balls are supplied to the other islands through the other island supply route. Furthermore, when the pachinko balls overflow in the other island supply route, the overflowed pachinko balls are sent to the overflow passage 22 of the own island through the own island return route. When the pachinko balls overflow in the self-island reflux path, the overflowing pachinko balls are guided toward the base tank B via the overflow ball guiding path. In addition, with respect to the basic structure of such an upper tank, the self-island return route is closed and the pachinko balls overflowing from the other island replenishment route are guided to the overflow guide route. Are used as the upper tanks 31 of the main pachinko island platform A1 and the upper tanks 32 to 34 of the slave pachinko island platforms A2 to A4 other than the main pachinko island platform A1. For this reason, the upper tank can be used in common for the main pachinko island platform A1 and the slave pachinko island platforms A2 to A4 with only a slight change.

  In addition, three openings (ball return ports 44 to 46) are formed in the outer wall plate 31c of the upper tank 31 provided in the main pachinko island platform A1 so as to be aligned in the vertical direction. For this reason, when the outer wall plate 31c having three openings is commonly used in the upper tanks 32-34 of the slave pachinko island platforms A2-A4 that do not require three openings arranged in parallel in the vertical direction. However, the three openings can be used effectively for adjusting the height of the AC rod attached to the upper tanks 32 to 34.

  Further, in the configuration of the upper tank, the AC rods 1b and 1d for returning the pachinko balls from the sub-pachinko island platforms A2 and A3 to the base tank B are provided through the upper tank 31 of the main pachinko island platform A1, The AC baskets 1b and 1d and the return basket 3 for returning the pachinko balls from the main pachinko island platform A1 to the base tank B are arranged side by side in the vertical direction. On the other hand, the base tank B is connected to the downstream ends of the baskets 3, 1b, 1d to return the branch box 134 for receiving the pachinko balls flowing down the baskets 3, 1b, 1d, and the return branch box Dispersion rods 135 and 136 that appropriately store the pachinko balls received by 134 in the storage space inside the base tank B according to the storage order inside the base tank B are provided. As a result, the pachinko balls from the main pachinko island stand A1 and the pachinko balls from the sub pachinko island stands A2 and A3 can be individually returned to the base tank B with the individual baskets 3, 1b, 1d. The ball can be returned quickly. However, the return branch box 134 provided in the base tank B and the dispersion baskets 135 and 136 can be commonly used for the baskets 3, 1b, and 1d. That is, since it is not necessary to provide the return branch box 134 and the dispersion baskets 135 and 136 individually for the baskets 3, 1b, and 1d, the number of parts constituting the base tank B can be reduced, and the base The assembly workability of the tank B can be facilitated.

  In addition, the own island replenishment route, the other island replenishment route, the own island recirculation route, and the overflow guidance route are formed in the upper tank, and the own island recirculation route and the overflow guidance route are adjacent to each other. Arrange. As a result, in the upper tank 31 of the main pachinko island stand A1, it is possible to easily create a configuration for closing the own island return route and guiding the pachinko balls overflowing from the other island supply route to the overflow guide route. In the configuration in which the tank is used in common by the main pachinko island platform A1 and the sub pachinko island platforms A2 to A4, the change work performed on the upper tank is facilitated.

  Moreover, the return rod 3 for returning the pachinko balls from the main pachinko island platform A1 to the base tank B is disposed above the AC rods 1b and 1d for returning the pachinko balls from the sub pachinko island platforms A2 and A3 to the base tank B. At this time, in the upper tank 31 of the main pachinko island stand A1, the pachinko balls overflowing from the other island replenishment route are directly guided to the overflow ball guiding route and returned from the return basket 3 to the base tank B. The pachinko ball always flows down, and the return basket 3 including the pachinko ball is heavy. The length of the return basket 3 is the same as the distance from the upper tank 31 to the base tank B of the main pachinko island platform A1 and is short. On the other hand, in the upper tanks 32 and 33 of the slave pachinko islands A2 and A3, the pachinko balls overflowing from the other island replenishment route are guided to the own island return route, and if the pachinko balls overflow in the own island return route, the overflow The pachinko ball is guided to the overflow guide route and returned to the base tank B from the AC rods 1b and 1d. For this reason, the AC rods 1b and 1d are in a state where the pachinko balls occasionally flow down, and the AC rods 1b and 1d including the pachinko balls are light in weight. The length of the AC rods 1b and 1d is the distance from the upper tanks 32 and 33 of the slave pachinko islands A2 and A3 to the base tank B, that is, at least the slave pachinko islands A2 and A3 and the base tank B. The length which crosses the arrangement space of the main pachinko island stand A1 interposed between them is necessary and long. Accordingly, since the return rod 3 with a short length is difficult to be accelerated at the time of flow down, the flow speed of the pachinko ball is slow, and the AC rods 1b and 1d having a long length are likely to be accelerated at the time of flow down. As a result, the alternating current rods 1b and 1d having a high flow velocity are arranged below the return rod 3 having a low flow velocity. As a result, the pachinko balls that are always discharged from the upper side (return basket 3) into the return branch box 134 are changed into the pachinko balls that are vigorously discharged from the lower side (AC poles 1b, 1d) into the return branch box 134. Since the momentum of discharge can be weakened by colliding from above, it is possible to prevent the pachinko balls discharged from the lower side from colliding with the inner wall portion of the return branch box 134 vigorously. Damage due to pachinko balls can be avoided.

  Further, in the configuration of the upper tank 33, the overflow ball guiding path for guiding the pachinko balls toward the base tank B is arranged in the upper tank 33 at a position closest to the installation location of the ball discharge rod 20 a of the ball feeding device 20. Has been. For this reason, in the ball rolling structure that rolls pachinko balls on the inclined surface in the upper tank 33, the overflow ball guiding path can be arranged at the most upstream position, and the ball receiving portion of the overflow ball guiding path Since the (upstream end portion) can be arranged at a high position, as a result, the downstream end portion serving as the ball discharge portion of the overflow guide path can also be arranged at a high position. Accordingly, in the configuration in which the AC rod 1d is bridged between the ball discharge portion (ball return port 83) of the overflow ball guiding path and the base tank B, the pachinko island platform A3 (upper tank 33) and the base tank B Even if the installation distance is somewhat long, the inclination angle necessary for smoothly flowing down the pachinko balls with the AC rod 1d can be maintained, so the pachinko island platform A3 (upper tank 33) and the base tank B There is no need to limit the installation distance between the two. As a result, between the pachinko island platform A3 (upper tank 33) and the base tank B, other pachinko island platforms (in this embodiment, the pachinko island platform A1 and the pachinko island platform A2) are interposed, and the pachinko island platform A3. Even when the installation distance between the (upper tank 33) and the base tank B is increased, the AC tank 1d is passed through the upper tanks 31 and 32 of the other pachinko islands A1 and A2 to overflow the ball. Since the pachinko balls from the guide path can be sent directly to the base tank B, island exchange can be performed smoothly.

  In addition, as described above, the overflow ball guiding path for guiding the pachinko balls toward the base tank B is disposed at a position closest to the installation location of the ball discharge rod 20a of the ball lifting device 20, thereby causing the overflow ball guiding path. As a configuration in which the downstream end portion serving as a ball discharge portion is arranged at a high position, the return position of the pachinko balls to the base tank B can be increased, so that the installation position of the receiving means on the base tank B side can be increased. As a result, the amount of ball storage in the base tank B can be increased.

  In addition, a first receiving path that accepts pachinko balls supplied from the other island replenishment path on the other island, a second receiving path that receives pachinko balls derived from the overflow guidance path on the other island, a self-island return path, An overflow rod 120 that joins pachinko balls flowing down the first receiving path and the second receiving path to guide the overflow path 22 is provided in the upper tank 33, and the second receiving path is positioned closest to the overflow path 22. The pachinko balls from the second receiving path are joined at the most downstream side of the overflow basket 120. As a result, the path length of the second receiving path can be formed with the shortest length in the upper tank 33, so that the path for guiding the excess pachinko balls to the base tank B in the pachinko island platform A3 is wasted. As a result, the smoothness of island exchange can be further enhanced.

  Moreover, the overflow ball guiding path and the second receiving path are stacked in the vertical direction and provided in the upper tank 33, so that the overflow ball guiding path and the base tank B of the upper tank 33 on the own island are spanned. An AC kite 1d and an AC kite 1f spanned between the overflow ball guiding path of the upper tank 34 on the other island and the second receiving path of the upper tank 33 on the own island are respectively viewed from the top of the pachinko island platform A3. They can be arranged in a straight line. For this reason, the path | route which guides the pachinko ball which became excessive in the pachinko island stand A3 to the base tank B is lost, and the smoothness of island exchange can be further improved.

  In addition to the self-island replenishment route, the other-island replenishment route, the self-island recirculation route, and the overflow ball guidance route, the upper tank 33 of the pachinko island stand A3 where the ball return device 5 is not installed is further provided with a first receiving route and A second receiving route is provided. Thereby, when a large amount of pachinko balls are returned from the ball return device 5 at the pachinko island stand A2 or the pachinko island stand A4 where the ball return device 5 is installed, and the pachinko balls in the island stand increase excessively, the pachinko island stand Since A3 can receive the excessive pachinko balls of the pachinko island platform A2 or the pachinko island platform A4 via the first receiving path or the second receiving path, the upper tank 32 of the pachinko island platform A2 or the pachinko island platform A4 It is possible to avoid a problem that the pachinko ball is full and punctured in the upper tank 34.

  In the above-described embodiment, the ball lifting device is placed horizontally (so that the ball discharging direction of the ball lifting device is parallel to the longitudinal direction of the pachinko island platform) with respect to the pachinko island platform according to the present invention. However, the present invention is not limited to this, and the ball lifting device is arranged vertically (the ball discharging direction of the ball lifting device is perpendicular to the longitudinal direction of the pachinko islands). A configuration of a placement method may be used. Further, in the embodiment, the ball lifting device is installed at a substantially central position of the pachinko island stand, but it is not limited to this configuration, and the ball lifting device is provided on one end side in the longitudinal direction of the pachinko island stand. An installed configuration may be used. Further, in the embodiment, the overflow passage is disposed at a substantially central position of the pachinko island platform that is in the vicinity of the ball lifting device, and accordingly, the confluence guide rod is disposed to be inclined downward to the center of the pachinko island platform. However, the present invention is not limited to this configuration. For example, when the overflow passage is installed on one end side in the longitudinal direction of the pachinko island base, the confluence guide rod may be arranged so as to be inclined downward toward one end side of the pachinko island base.
