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 main pachinko island platform A1 has been described above, the upper tank 31 provided on the main pachinko island platform A1 guides pachinko balls to each pachinko machine 10 on its own island with the highest priority, and its guidance is necessary. When it disappears, it guide | induces to sub pachinko island stand A2 via the alternating current pole 1a, and when the guidance becomes unnecessary, it guide | induces to the base tank B via the return pole 3. Thereby, the replenishment of the pachinko ball to the self-island and the supply of the pachinko ball to the slave pachinko island stand A2 can be performed smoothly. The pachinko balls discharged from the ball discharge rod 20a are set to fall within the range straddling the ball sorting plate 61 and the first guide plate 64, and the pachinko balls are individually and evenly distributed to the ball feeding paths 62 and 72. You may make it replenish.

  By the way, as a structure of the upper tank 31 provided in the main pachinko island stand A1 adjacent to the base tank B, the upstream portion of the return cage 3 is installed as described above, and the downstream portion of the AC cage 1b is penetrated. An installation space 52 is provided, and the return rod 3 and the AC rod 1b are connected to the base tank B at their downstream ends. Hereinafter, the return basket 3 and the AC basket 1b provided between the upper tank 31 and the base tank B of the main pachinko island stand A1 and the base tank to which the downstream ends of the return basket 3 and the AC basket 1b are connected. B will be described with reference to FIG. FIG. 6 is a perspective view showing a state in which the upper tank 31 and the base tank B of the main pachinko island stand A1 provided adjacent to the base tank B are connected via the return basket 3 and the AC basket 1b.

  As shown in FIG. 6, between the upper tank 31 and the base tank B of the main pachinko island stand A1, the return rod 3 and the alternating current rod 1b are erected 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 35 and the non-priority tank part 36 in which the storage order in which pachinko balls are stored is determined. And a dispersion mechanism 37 that disperses pachinko balls returned to the base tank B and located above the priority tank part 35 and the non-priority tank part 36.

  The dispersion mechanism 37 includes a return branch box 38 disposed and fixed substantially at the upper center of the base tank B, a return ball priority dispersion basket 39 inclined downward from the return branch box 38 toward the priority tank unit 35, A return ball non-priority dispersion basket 40 that is inclined downward from the return branch box 38 toward the non-priority tank section 36 side. Guide plates 41 are provided on both sides of the upstream end of the return ball priority dispersion basket 39. The guide plate 41 has a function of reliably guiding the pachinko balls to the priority tank portion 35 and facilitating the flow of the pachinko balls to the downstream end of the priority tank portion 35. Further, since the pachinko ball does not fall from the portion where the guide plate 41 is provided, it is below the guide plate 41, that is, adjacent to the non-priority tank portion 36 and downstream of the priority tank portion 35. It also has a function of not depositing pachinko balls that fall directly from the return ball priority dispersion basket 39 in the vicinity.

  The return branch box 38 is formed in a rectangular parallelepiped shape whose upper surface is opened with a plywood (which may be a metal plate), and a priority port 42 is formed below the surface on the priority tank portion 35 side.

A ball feed passage 123 for feeding the pachinko balls overflowing in the ball feed passage 109 into the second overflow rod 122 for guiding the ball to the second overflow passage 26 is formed in 93. Note that the communication port 117, the connecting rod 118, and the ball feeding passage 123 constitute an overflow ball passage according to the present invention.

  Furthermore, in the ball distribution space 91 of the upper tank 32, unlike the ball distribution space 61 of the upper tank 31 provided in the main pachinko island platform A1, the position below the position where the upstream end of the AC basket 1c is arranged, A ball rolling plate 113 is provided as a first receiving path for receiving a pachinko ball discharged from the AC rod 1a connected to the ball receiving port 47 and rolling the pachinko ball to the upstream side of the first overflow rod 121. . In addition, the ball installation space 92 is provided with a ball rolling plate 114 as a second receiving path that receives the pachinko balls discharged from the AC rod 1d and rolls them to the downstream side of the first overflow rod 121. Yes. Thereby, the pachinko balls fed into the upper tank 32 from the AC rod 1a (main pachinko island platform A1) flow into the upstream portion of the first overflow rod 121 via the ball rolling plate 113, and the above-described ball swing Pachinko balls overflowing beyond the upper end of the partition plate 110 on the partition plate 101 flow into the middle stream side portion of the first overflow rod 121 through the ball feed passage 109, and the upper portion from the AC rod 1d (second pachinko island platform A3). The pachinko balls fed into the tank 32 flow into the downstream portion of the first overflow rod 121 via the ball rolling plate 114, and these pachinko balls are merged on the first overflow rod 121 to form the first overflow passage. 22 is sent.

  In addition, between the downstream end of the ball rolling plate 114 and the first overflow rod 121, a guide rod 124 that is inclined downward in the direction from the ball distribution space 91 to the lifting device installation space 93 is provided, The downstream end of the guide rod 124 is connected to the upstream end of the second overflow rod 122 through a communication port 125 formed in the partition plate 119. As a result, when the pachinko balls sent to the first overflow rod 121 via the ball rolling plate 114 are full on the first overflow rod 121, the pachinko balls that subsequently flow down the ball rolling plate 114 are guided. By being guided to the second overflow trough 122 through the trough 124, it is finally sent to the second overflow passage 26.

  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. As a self-island replenishment route for feeding the balls into the pachinko machine 10 arranged on the island platform on the opposite side of the ball discharge port 20b of the ball feeding device 20 (left side of the ball lifting device 20 shown in FIG. 7). A ball feed passage 115 is formed. At the downstream end of the ball feed passage 115, a lead-out port for leading the pachinko balls that have flowed down the ball feed passage 115 to the replenishment rod 21 on the opposite side of the ball discharge port 20b (the left side of the ball feeding device 20 shown in FIG. 7). 116 is provided.

  Thus, in the configuration of the upper tank 32 described above, the pachinko balls discharged from the ball discharge rod 20a of the ball lifting device 20 are on the ball distribution plate 101 fixed to the upper portion of the ball distribution space 91 in an inclined manner. Fall into. 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 (ball flow (a) shown in FIGS. 8 and 9). 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 (ball flow (b) shown in FIGS. 8 and 9). In addition, some pachinko balls out of the pachinko balls discharged from the ball discharge rod 20a of the ball lifting device 20 are directly dropped on the first guide plate 104 and directly to the second guide plate 105 side. It is supposed to be sent. 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 1c and supplied to the upper tank 33 of the pachinko island platform A3. (Ball flow (c) shown in FIGS. 8 and 9).

  Further, the pachinko balls fed from the main pachinko island A1 through the alternating current rod 1a into the upper tank 32 are guided to the upstream portion of the first overflow rod 121 through the ball rolling plate 113 (FIG. 9). And the ball flow (1) shown in FIG. The pachinko balls overflowing beyond the upper end of the partition plate 110 on the ball distribution plate 101 are guided to the middle stream side portion of the first overflow trough 121 through the ball feed passage 109 (the balls shown in FIGS. 8 to 11). Flow (d)). Then, these pachinko balls are merged on the first overflow rod 121 which is the middle stream side portion and fed into the first overflow passage 22 (ball flow (2) shown in FIGS. 9 and 11).

  In addition, when the pachinko balls are full in the first overflow passage 22 (first overflow bowl 121) and the pachinko balls are stacked in the ball feed passage 109, first, the pachinko balls are swung through the communication port 112. It overflows from the separation space 91 to the side of the fence installation space 92. Then, the pachinko balls are discharged to the upstream portion of the AC basket 1b installed in the basket installation space 92 (ball flow (e) shown in FIGS. 9 to 11). Further, when the pachinko balls are stacked in the ball feed passage 109 despite the discharge of the pachinko balls to the AC rod 1b, the pachinko balls in the ball feed passage 109 are connected from the communication port 117. The ball is fed into the ball feeding passage 123 through 118, and is guided from the ball feeding passage 123 to the second overflow rod 122 (ball flow (f) shown in FIGS. 8, 10, and 11). These pachinko balls are finally fed into the second overflow passage 26 through the second overflow trough 122. In addition, the ball flow (e) in which the pachinko balls are filled in the first overflow rod 121 and stacked in the ball feeding passage 109 are discharged to the AC rod 1b through the communication port 112 is as described above. The ball flow (2) from the ball feed passage 109 to the first overflow rod 121 is blocked by a ball flow (3) in which a pachinko ball from a slave pachinko island base A3 described later is fed into the first overflow passage 22. It has come to occur.

  Further, the pachinko balls sent from the sub pachinko island platform A3 through the AC rod 1d into the upper tank 32 are guided to the downstream portion of the first overflow rod 121 via the ball rolling plate 114 (FIG. 9). The ball flow shown in (A)). Then, these pachinko balls are merged on the first overflow rod 121 which is the downstream side portion and sent into the first overflow passage 22 (ball flow (3) shown in FIGS. 9 and 11). The pachinko balls fed into the first overflow passage 22 (first overflow rod 121) via the ball rolling plate 114 are filled on the first overflow rod 121, and further on the ball rolling plate 114. When the pachinko ball flows down, the pachinko ball is guided to the second overflow rod 122 through the guide rod 124 and is sent to the second overflow passage 26 (ball flow (B) shown in FIG. 9). ).

  As described above, the pachinko balls polished and polished by the ball lifting device 20 are first distributed so as to be preferentially replenished to the replenishment basket 21 (pachinko machine 10) on its own island. Strictly speaking, the pachinko machine 10 on the side of the ball discharge port 20b is replenished by the above-described ball flow (a) serving as a self-island replenishment, and then the opposite side to the ball discharge port 20b by a ball flow (b) serving as a self-island replenishment. The pachinko machine 10 is replenished. Next, as the priority in the ball flow of the pachinko balls lifted on its own island, the pachinko balls dropped downward from the dropping port 107 of the ball sorter plate 101 are sent to the AC fence 1c and adjacent to the pachinko balls. The ball flow (c) to be replenished to the upper tank 33 of the island platform A3, and the pachinko balls overflowing beyond the upper end of the partition plate 110 on the ball distribution plate 101 pass through the ball feed passage 109. The ball flow (d) that is the self-island return guided to the first overflow rod 121, and the pachinko balls that are full in the first overflow rod 121 and stacked in the ball feed passage 109 pass through the communication port 112. The ball flow (e) that leads to the overflow ball discharged to the AC rod 1b through, and the pachinko balls continuously stacked in the ball feed passage 109 in spite of the discharge of the pachinko ball to the AC rod 1b Contact from mouth 117 Through the trough 118 is fed into the ball feeding passageway 123, a second overflow become balls stream derived from 該玉 feed path 123 to the second overflow trough 122 (f), in that order of. In addition, each communicating port 112,117 which discharges | emits the pachinko ball laminated | stacked in the ball | bowl feeding path | pass 109 is the magnitude | size which can discharge | emit all the amount of pachinko ball lifted by the ball lifting device 20 (about 16,000 pieces per minute), respectively. Is set to For this reason, unless the ball flow (e) to the communication port 112 stops, the ball flow (f) to the communication port 117 does not occur. Here, the effect of feeding the pachinko ball flowing down the overflow ball passage (ball flow (f)) of the upper tank to the second overflow passage on another island preferentially over the pachinko balls flowing down the second receiving path will be described. Then, the situation where the ball flow of pachinko balls occurs in the overflow passage is that the overflow ball is sent to the upper tank of the secondary pachinko island stand (pachinko island stand A2) adjacent to the large storage tank (base tank B) side. The island is full of pachinko balls, and the only escape route is the second storage space on the island. On the other hand, pachinko balls that are fed from the secondary pachinko island stand (pachinko island stand A4) adjacent to the opposite side of the large storage tank and are filled in the second receiving path (ball flow (B)) Even if the pachinko ball could not be guided to the second storage space, the ball flow that is guided to the second storage space with the highest priority in the upper tank of the slave pachinko island adjacent to the opposite side of the large storage tank (in the overflow passage) ). Therefore, priority can be given to the ball flow of the 2 paths (overflow passage and second receiving path) stored in the 2nd storage space, and the whole ball flow can be made smooth.

  Further, as the priority order of the ball flow of the pachinko balls sent from the first overflow rod 121 to the first overflow passage 22, the pachinko balls sent from the adjacent sub-pachinko islands A3 to the upper tank 32 through the AC rod 1d. The ball is guided to the downstream portion of the first overflow rod 121 and fed into the first overflow passage 22 (3), and the pachinko balls overflowing beyond the upper end of the partition plate 110 on the ball distribution plate 101 The ball flow (2) guided through the ball feed passage 109 to the middle portion of the first overflow rod 121 and fed into the first overflow passage 22, the upper tank 32 from the main pachinko island platform A1 through the AC rod 1a. The pachinko balls fed in are guided to the upstream portion of the first overflow rod 121 through the ball rolling plate 113 and the first Ball stream fed into the Furo passageway 22 (1), in that order of. In addition, the pachinko ball sent into the upper tank 32 from the adjacent sub pachinko island platform A3 through the AC rod 1d is downstream of the first overflow rod 121 via the ball rolling plate 114 by the ball flow (A). When the pachinko ball is full on the first overflow rod 121, then the pachinko ball is guided to the second overflow rod 122 through the guide rod 124 by the ball flow (B). Further, the priority order of the pachinko balls fed into the second overflow passage 26, in other words, the priority order of the pachinko balls joined to the second overflow cage 122 is guided from the ball feed passage 123 to the second overflow cage 122. The ball flow (f) is given priority, and then the ball flow (B) is guided from the ball rolling plate 114 to the second overflow rod 122 through the guide rod 124.

  Next, the structure of the lower storage tank 25 will be described with reference to FIGS. FIG. 13 is a perspective view showing the upper tank 32 and the lower storage tank 25 provided on the slave pachinko island platform A2 that is not adjacent to the base tank B. FIG. FIG. 14 is a perspective view of a state in which the inside of the lower storage tank 25 is seen through from the first side plate 140a side. FIG. 15 is a perspective view showing the ball merge portion 171 of the lower storage tank 25. FIG. 16 is a plan view showing the ball merge portion 171 of the lower storage tank 25.

  First, the lower storage tank 25 is installed in the lower space of about two to three pachinko machines 10 to the right side from the ball lifting device 20 of the sub-pachinko island platform A2 (see FIG. 7), and FIG. 13 to FIG. As shown in FIG. 16, it is constituted by a rectangular parallelepiped tank base in which an upper surface opening 25a for directly receiving a pachinko ball falling from above is formed. The tank base includes a first side plate 140a, a second side plate 140b, a front plate 141, a rear plate 142, and a bottom plate 143. The pachinko balls that directly enter the lower storage tank 25 directly from the upper surface opening 25 a are adjacent to the six pachinko machines 10 disposed at an upper position within the longitudinal width of the lower storage tank 25 and the pachinko machine 10. This is a pachinko ball discharged from the ball lending machine 19.

  In the center of the upper end portion of the front plate 141, introduction ports 144a and 144b to which the guide paths 24 and 28 are individually connected are formed vertically. From the upper inlet 144a toward the rear plate 142, the pachinko balls that have overflowed the upper tank 32 and then flowed down the second overflow passage 26 are guided from one end to the other end in the lower storage tank 25. A second upper guide rod 146 is provided to be inclined downward. The second upper guide rod 146 is formed with a width dimension substantially the same as the opening width of the introduction port 144 a, and its downstream end is in contact with the inner wall surface of the rear plate 142. A pair of left and right rubber plates 29 having a height width equal to or greater than one pachinko ball from the bottom surface of the guide path 28 are provided at both ends in the lateral width direction of the guide path 28. The rubber plate 29 is a ball for receiving the pachinko balls discharged from the two pachinko machines 10 (including the adjacent ball lending machine 19) installed beside the lower storage tank 25 side of the ball lifting device 20. It functions as a receiving plate and guides the received pachinko balls into the lower storage tank 25.

  The pachinko balls that have fallen on the rubber plate 29 are guided to the second upper guide rod 146 together with the pachinko balls that have fallen onto the bottom surface of the guide path 28 from the rubber plate 29 and overflowed from the upper tank 32. Others roll on the rubber plate 29 as they are and fall into a first storage space 131 described later. For this reason, even when the pachinko balls overflowing from the upper tank 32 flow down on the guiding path 28 vigorously, the pachinko balls on the rubber plate 29 cannot fall on the guiding path 28 and fall on the rubber plate 29. The pachinko balls thus rolled roll on the rubber plate 29 and are surely fed into the lower storage tank 25. Further, the side wall surface of the rubber plate 29 facing the center side of the guide path 28 gradually narrows the bottom surface width of the guide path 28 from the upstream side to the downstream side of the guide path 28, and the bottom surface of the guide path 28 at the downstream end. The width is formed to be substantially the same as the width of the second upper guide rod 146. As a result, the pair of left and right rubber plates 29 also have a function of gradually gathering the pachinko balls fed into the guide path 28 within the width of the second upper guide rod 146 as it flows down.

  On the other hand, from the lower inlet 144b toward the rear plate 142, the pachinko balls that have overflowed the upper tank 32 and then flowed down the first overflow passage 22 are guided from one end to the other end in the lower storage tank 25. A first upper guide rod 145 is provided to be inclined downward. The downstream end of the first upper guide rod 145 is in contact with a partition plate 147 that is erected at a position that partitions the interior of the lower storage tank 25 in a substantially one-to-three manner in the longitudinal direction. As a result, the pachinko balls fed from the first overflow passage 22 into the lower storage tank 25 are stored in the first storage space 131 serving as a storage space on the front plate 141 side partitioned by the partition plate 147. On the other hand, the pachinko balls fed into the lower storage tank 25 from the second overflow passage 26 described above flow down the second upper guide rod 146 and then become a storage space on the rear plate 142 side partitioned by the partition plate 147. It is stored in the second storage space 132. In addition, a notch portion 147 a for communicating the second upper guide rod 146 disposed above the first upper guide rod 145 from the first storage space 131 to the second storage space 132 is formed at the upper end portion of the partition plate 147.

The front plate 141 has a lead-out port 153 for connecting the downstream end of the first bottom plate 175 to the introduction rod 16. In addition, the corner portion between the first side plate 140a and the front plate 141 on the first bottom plate 175 is guided to prevent the pachinko balls flowing down the first bottom plate 175 from clogging at the corner portion. A protruding piece 154 is provided.

  A second bottom plate 176 is provided between the partition plate 147 and the first partition plate 173 so as to be inclined downward from the second side plate 140b toward the first side plate 140a. The upstream end of the second bottom plate 176 is in contact with the inner wall surface of the second side plate 140b. On the other hand, the downstream end of the second bottom plate 176 is arranged at a predetermined interval from the inner wall surface of the first side plate 140a, and is located upstream of the first bottom plate 175, like the other side ends of the partition plates 173 and 174. It is designed to communicate with each other. In addition, a downstream end portion of the collection passage 150 penetrating the partition plate 147 is disposed above the downstream end of the second bottom plate 176. Unlike the closed cross-sectional shape arranged in the second storage space 132, the downstream end portion of the recovery passage 150 is a downstream end plate portion 150a configured by only the bottom plate, and the pachinko ball that has flowed down the recovery passage 150 Are discharged from the downstream end plate 150a to the first bottom plate 175 and the third bottom plate 177.

  A third bottom plate 177 is provided between the first partition plate 173 and the second partition plate 174 so as to be inclined downward from the second side plate 140b toward the first side plate 140a.

It is designed to communicate with each other. Further, a connecting port 155 to which the connecting rod 17 is connected is formed in a portion of the front plate 141 corresponding to the upstream portion of the second bottom plate 176. As a result, the communication rod 17 communicates with the upstream portion of the fourth bottom plate 178, and the pachinko balls flowing down the collection rod 12 on the side where the lower storage tank 25 is not disposed are connected to the communication rod 17. It is guided to the fourth bottom surface plate 178 of the ball meeting part 171 through.

  The structure of the lower storage tank 25 has been described above. Next, the operation of the lower storage tank 25 will be described along the flow of pachinko balls. First, pachinko balls that have overflowed from the first overflow rod 121 of the upper tank 32 are guided to the first upper guide rod 145 in the first storage space 131 via the first overflow passage 22 and the guide passage 24, and the first It is dropped and stored on the inclined plate 172 of the ball junction 171 from the upper guide rod 145. Then, the pachinko balls on the inclined plate 172 fall from the drop port 172a to the upstream portion of the second bottom plate 176, and after flowing down the second bottom plate 176, are sent to the upstream portion of the first bottom plate 175 (FIG. 15). And the ball flow (4) shown in FIG.

  The pachinko balls that have overflowed from the second overflow rod 122 of the upper tank 32 are guided to the second upper guide rod 146 in the second storage space 132 via the second overflow passage 26 and the guide passage 28, and the second The upper guide rod 146 is dropped and stored on the first bottom plate portion 148 and the second bottom plate portion 149. The pachinko balls on the first bottom plate portion 148 are guided to the second bottom plate portion 149 along with the inclination of the first bottom plate portion 148, and the pachinko balls on the second bottom plate portion 149 flow down the second bottom plate portion 149. After that, it is fed to the upstream portion of the first bottom plate 175 in the ball joint portion 171 through the communication cutout portion 152 (ball flow (3) shown in FIGS. 15 and 16).

  Further, the pachinko balls 10 discharged from the pachinko machine 10 located on the side where the lower storage tank 25 is not disposed and the ball lending machine 19 adjacent to the pachinko machine 10 are passed from the collection basket 12 through the contact rod 17 and the ball junction 171. It is guided to the inner fourth bottom plate 178, and after flowing down the fourth bottom plate 178, it is sent to the downstream portion of the first bottom plate 175 (ball flow (2) shown in FIGS. 15 and 16).

  Further, the pachinko balls discharged from the pachinko machine 10 located on the side where the lower storage tank 25 is disposed and the ball lending machine 19 adjacent to the pachinko machine 10 are collected from the collection basket 12 in the second storage space 132. 150 is guided to the third bottom surface plate 177 in the ball meeting portion 171, flows down the third bottom surface plate 177, and then is fed into the middle portion of the first bottom surface plate 175 (the ball flow shown in FIGS. 15 and 16). (1)).

  However, the recovery basket 12 on the side where the lower storage tank 25 is arranged is configured to guide the pachinko balls returned to the ball return device 5 to the lower storage tank 25 as well. When the number of pachinko balls flowing down the collection basket 12 on the side where the tank 25 is disposed increases, the pachinko balls are discharged not only to the third bottom plate 177 but also to the first bottom plate 175. ing. That is, when the pachinko balls are not returned to the ball return device 5, the pachinko balls that have flowed down the collection passage 150 are preferentially transferred from the downstream end plate portion 150a serving as the downstream end of the collection passage 150 to the third bottom surface plate 177. It is fed (ball flow (A) shown in FIGS. 15 and 16). When the number of pachinko balls returned to the ball return device 5 and the amount of pachinko balls flowing down the recovery basket 12 increases, the pachinko balls discharged from the downstream end plate portion 150a are added to the ball flow (A). It is simultaneously sent to the 1 bottom plate 175 (ball flow (B) shown in FIGS. 15 and 16).

  Then, as described above, the pachinko balls fed into the ball confluence portion 171 through the respective ball flows are merged at the first bottom plate 175 and passed through the introduction rod 16 from the outlet port 153 of the front plate 141. It is sent to the lifting device 20. By the way, as a pachinko ball joined to the first bottom surface plate 175 of the ball joining portion 171, the third bottom surface plate 177 flows down from the collection passage 150 by the ball flow (1) and is sent to the middle portion of the first bottom surface plate 175. The pachinko balls from the recovery basket 12 that are the pachinko balls that are sent down to the downstream portion of the first bottom plate 175 by flowing down the fourth bottom plate 178 from the contact rod 17 by the ball flow (2) are most preferential. To the first bottom plate 175. Next, as a priority order in the ball flow of the pachinko balls joined to the first bottom plate 175, the first bottom plate 175 flows down the second bottom plate portion 149 in the second storage space 132 by the ball flow (3). The upstream portion of the first bottom surface plate 175 flows down the second bottom surface plate 176 in the first storage space 131 by the pachinko balls and ball flow (4) that are pachinko balls fed into the upstream portion of the first storage space 131 The pachinko balls from the first overflow passage 22 are the pachinko balls that are fed into the order.

  Next, FIG. 17 thru | or FIG. This will be described with reference to FIG. FIG. 17 thru | or FIG. 19 is a side view which shows the ball flow effect | action of the pachinko ball between subordinate pachinko island stand A2-A4, respectively. In addition, in the following description, the ball | bowl flow effect | action when the pachinko ball in an island stand increases excessively with the return of the pachinko ball to the ball return apparatus 5 is demonstrated.

  First, as shown in FIG. 17A, in the state where no pachinko balls are returned to any of the ball return devices 5 of the slave pachinko islands A2 and A4, any slave pachinko islands A2 to A2 are used. Even in A4, the pachinko balls in the islands A2 to A4 do not increase excessively, so pachinko balls are not exchanged between the islands A2 to A4. Thereafter, as shown in FIG. 17 (B), when the pachinko balls are returned to the ball returning device 5 of the slave pachinko island stand A4 farthest from the base tank B, the pachinko balls are separated from the recovery basket 12 and the lower part. The ball is fed from the ball lifting device 20 to the upper tank 34 via the storage tank 25. The pachinko balls thus fed into the upper tank 34 become excessive pachinko balls in the sub-pachinko island platform A4. Therefore, the pachinko balls pass from the ball feed passage 109 of the upper tank 34 through the communication port 112 and are exchanged. It is guided to 1f (corresponding to the ball flow (e) to the AC basket 1b in the upper tank 32 described above), and sent to the adjacent slave pachinko island platform A3 through the AC basket 1f.

  Further, in the adjacent slave pachinko island platform A3, the pachinko balls received from the slave pachinko island platform A4 via the AC rod 1f pass from the ball rolling plate 114 of the upper tank 33 through the first overflow rod 121 to the first overflow. It overflows into the passage 22 (corresponding to the ball flow (3) to the first overflow passage 22 in the upper tank 32 described above). Thereafter, the pachinko balls are fed into the first storage space 131 of the lower storage tank 25 and then guided to the ball lifting device 20 from the ball joining portion 171 and are transported from the ball lifting device 20 to the upper tank 33. The The pachinko balls thus fed into the upper tank 33 become excessive pachinko balls in the sub-pachinko island platform A3. Therefore, the pachinko balls pass from the ball feed passage 109 of the upper tank 33 through the communication port 112 and are exchanged. 1d (corresponding to the ball flow (e) to the AC basket 1b in the upper tank 32 described above) and sent to the slave pachinko island platform A2 close to the base tank B through the AC basket 1d.

  In the secondary pachinko island platform A2, the pachinko balls received from the secondary pachinko island platform A3 via the AC rod 1d pass from the ball rolling plate 114 of the upper tank 32 through the first overflow rod 121 and the first overflow passage 22. Overflow (ball flow (3)). After that, the pachinko balls are fed into the first storage space 131 of the lower storage tank 25 and then guided from the ball junction 171 to the ball lifting device 20 and are transported from the ball lifting device 20 to the upper tank 34. The The pachinko balls thus fed into the upper tank 34 become excessive pachinko balls in the sub-pachinko island platform A2, and therefore, the AC ball passes through the communication port 112 from the ball feed passage 109 of the upper tank 34. 1b (ball flow (e)), passes through the upper tank 31 of the main pachinko island stand A1 through the alternating current rod 1b, and is sent to the base tank B.

  By the way, during the transfer of the pachinko balls from the slave pachinko island platform A4 side farthest from the base tank B via the AC rods 1f, 1d, 1b as described above to the base tank B side, the slave pachinko close to the base tank B When the pachinko balls are returned to the ball return device 5 of the island stand A2, the pachinko balls are transferred to the ball feeding device 20 via the recovery basket 12 and the lower storage tank 25 as shown in FIG. To the upper tank 32. In this case, an excess of pachinko balls are fed into the upper tank 32 together with the pachinko balls from the slave pachinko island platform A3 described above. For this reason, in the upper tank 32, clogging occurs in a path (first overflow rod 121) for feeding the pachinko balls to the first overflow passage 22, and accordingly, the second overflow rod 122 to the second overflow passage 26. The pachinko ball overflows, and the excessive pachinko ball is stored in the second storage space 132 of the lower storage tank 25.

  Thereafter, when the overflow from the second overflow passage 26 described above continues and the pachinko balls stored in the second storage space 132 become full, as shown in FIG. Clogging will occur. For this reason, even in the upper tank 32, clogging occurs in a path through which the pachinko balls are fed into the second overflow passage 26. Specifically, clogging occurs on the second overflow rod 122 connected to the second overflow passage 26 and on the ball rolling plate 114 that feeds the pachinko balls into the second overflow rod 122. As a result, clogging occurs even in the AC rod 1d connected to the ball rolling plate 114.

  Then, clogging also occurs in the upper tank 33 of the slave pachinko island platform A3 on the side where the pachinko balls are fed to the slave pachinko island platform A2 via the AC rod 1d. Specifically, clogging occurs in a ball feed passage 109 that feeds pachinko balls to the AC rod 1d through the communication port 112. For this reason, pachinko balls overflowing from the upper end of the ball feed passage 109 are guided from the communication port 117 through the connection rod 118 to the ball feed passage 123 and then from the second overflow rod 122 through the second overflow passage 26. It is fed into the second storage space 132 of the lower storage tank 25 of the slave pachinko island stand A2. After that, the pachinko ball that has become excessive in the sub-pachinko island platform A3 is overflowed by the stoppage of the pachinko ball from the sub-pachinko island platform A3 to the sub-pachinko island platform A2 via the AC rod 1d. It is fed into the passage 26 and stored in the second storage space 132 of the lower storage tank 25 of the sub-pachinko island platform A3.

  That is, if the pachinko balls in the slave pachinko island platform A2 are excessively increased by the return of the pachinko balls to the ball return device 5 of the slave pachinko island platform A2 close to the base tank B, it becomes excessive. The pachinko balls are stored in the second storage space 132 of the lower storage tank 25 of the slave pachinko island platform A2, and when the storage in the second storage space 132 is full, the slave pachinko next to the base tank B is filled. Pachinko balls are stored in the second storage space 132 of the lower storage tank 25 of the slave pachinko island platform A3 adjacent to the island platform A2.

  After that, as shown in FIG. 19A, when the pachinko ball return to the ball return device 5 of the slave pachinko island stand A2 close to the base tank B is completed, the base tank from the slave pachinko island stand A2 through the AC rod 1b By continuously feeding the pachinko balls to B, the clogged state in the second storage space 132 of the lower storage tank 25 of the sub-pachinko island platform A2 is eliminated, and accordingly, the ball of the AC basket 1d is removed. The clogged state is cleared.

  Then, as shown in FIG. 19B, when the return of the pachinko balls to the ball return device 5 of the slave pachinko island stand A4 farthest from the base tank B is also completed, the slave pachinko island stand A4 passes through the alternating current pole 1f. The pachinko balls are then fed to the slave pachinko island platform A3, and then the pachinko balls stored in the second storage space 132 of the lower storage tank 25 of the slave pachinko island platform A3 pass through the alternating current pole 1d. By being sent to the island platform A2, the pachinko balls stored in the second storage space 132 of the lower storage tank 25 of the slave pachinko island platform A3 are eliminated. Thereafter, the feeding of the pachinko balls from the slave pachinko island platform A3 to the slave pachinko island platform A2 via the AC rod 1d is completed, and the pachinko machine in the second storage space 132 of the lower storage tank 25 of the slave pachinko island platform A2 is finished. The storage of the balls is eliminated, and the state returns to the state shown in FIG. 17A, that is, the state where no pachinko balls are exchanged between the pachinko islands A2 to A4 without the occurrence of excessive pachinko balls. .

  As described above, according to the configuration of the present embodiment, the replenishment and recovery AC fence 1a constructed between the pachinko island platforms A1 and A2, between the pachinko island platforms A2 and A3, and between the pachinko island platforms A3 and A4. ~ 1f (other island replenishment dredging and other island collecting dredging) are provided one by one at a predetermined inclination angle, and by the inclination of the alternating current reeds 1a to 1f erected to exchange pachinko balls between the pachinko islands A1 to A4 Perform by natural flow. Thereby, the appearance of the pachinko islands A1 to A4 as a whole can be improved, and since there is no need to provide control parts such as a ball quantity detection sensor and a shutter device, the system configuration of the island AC type ball transfer system Product unit price can be reduced. Furthermore, in such a system configuration, when the pachinko ball overflows in the exchange basket 1d which is the other island recovery basket of the pachinko island platform A3, the overflowing pachinko ball becomes the ball storage section of the pachinko island platform A3. 2 is stored in the storage space 132. For this reason, the trouble which stops the ball flow of the pachinko ball as the whole system by the clogging of the pachinko ball can be avoided, and as a result, the pachinko ball between each pachinko island platform A1 to A4 and the base tank B Can be reliably and smoothly performed.

  In addition, with the above-described configuration, a large amount of pachinko balls are returned to the ball return device 5 installed on the pachinko island platform A2, so that the pachinko balls are full in the upper tank 32 of the pachinko island platform A2, and accordingly When the pachinko ball is filled with the pachinko island stand A3, which is arranged adjacent to the pachinko island stand A2, the pachinko ball overflows from the upper tank 33 of the pachinko island stand A3. The pachinko balls are stored in the second storage space 132 in the lower storage tank 25 through the second overflow passage 26. As a result, even when a large amount of pachinko balls are returned to the ball return device 5 installed on the pachinko island stand A2, the problem of stopping the pachinko ball flow as a whole system due to clogging of the pachinko balls is avoided. As a result, the pachinko balls between the pachinko islands A1 to A4 and the base tank B can be exchanged reliably and smoothly.

  The ball flow priority order of the own island supply route, the other island supply route, and the own island return route is not limited to the configuration described in the embodiment. For example, the other island supply route, the own island supply route The ball flow priority order may be set higher in the order of the self-island return route.
