DETAILED DESCRIPTION OF THE INVENTION
Hereinafter, embodiments of the present invention will be described with reference to the drawings. First, a schematic configuration of the pachinko island stand 1 according to the present embodiment will be described with reference to FIG. Drawing 1 is a longitudinal section of pachinko island stand 1 concerning an embodiment. In FIG. 1, as is well known, a pachinko island platform 1 has a rectangular parallelepiped frame structure, and a pachinko machine 2 is arranged in the back side at the center in the longitudinal side surface. The pachinko island platform 1 is also provided with a ball return device 3 in parallel with the pachinko machine 2 for returning the pachinko balls acquired by the pachinko machine 2 to one side of the ball lifting device storage unit 4 in the center. However, it is desirable that the ball return device 3 is provided on the pachinko machine row side in which a non-priority side storage tank 10 described later is built. This is because it is possible to reliably return the prize balls from the ball return device 3 to the non-priority storage tank 10 which is almost full in a normal business state. Note that a return opening is formed in the ball return device 3, and the pachinko balls (prize balls) returned from the return opening are guided onto the transport rods 27 and 28 described later. Further, the return port of the ball return device 3 is driven to open and close by an electric drive source (for example, a motor or a solenoid) (not shown).
[0009]
In addition, a ball lifting device storage unit 4 is configured in the approximate center of the pachinko island stand 1, and a ball lifting device 5 is stored and installed in the ball lifting device storage unit 4. The ball lifting device 5 according to the present embodiment lifts a pachinko ball by a belt-shaped transport belt (not shown in detail), and the belt-shaped transport belt is installed in the vertical direction with respect to the pachinko island platform 1. The pachinko ball is lifted up. An upper tank 6 for temporarily storing the pachinko balls that have been lifted is provided at the top of the ball lifting device 5. From the upper tank 6, replenishment rods (not shown) are provided on the left and right sides in an inclined manner so that pachinko balls flow down from the upper tank 6. A distribution chute (not shown) corresponding to each pachinko machine 2 is provided in the replenishing basket, and a pachinko ball that flows down the replenishing basket is taken in. Pachinko balls taken in by the distribution chute are counted by a counting device (not shown) provided at the lower portion of the distribution chute, and then supplied to a prize ball tank (not shown) provided at the upper back of the pachinko machine 2 to play the game. Is used as a prize ball to be paid out to the player. In FIG. 1, a pachinko island stand 1 without a pedestal ball lending machine is shown. However, in the case where a pedestal ball lending machine is provided so as to be sandwiched between each pachinko machine 2, Is provided with a distribution chute so as to be compatible with this machine.
[0010]
On the other hand, the used balls discharged from each pachinko machine 2 are discharged downward from a ball discharge nozzle 7a (see FIG. 2) of an out ball box 7 having a counting function. The ball discharge nozzle 7a is arranged facing an upper priority basket 29 (described later) provided at the upper part of the storage tanks 9 and 10. As a result, the pachinko balls discharged from the out ball box 7 are guided to the upper priority basket 29 in the storage tanks 9 and 10. In addition, since the storage tanks 9 and 10 are each formed in a length corresponding to 3 to 4 pachinko machines 2 (so-called one-unit island length), the storage tanks 9 and 10 are stored in the units. When the unit island is further connected to the outside of the island (in many cases, connected), the out ball guide rail 8 is provided at the lower center of the unit island connected to the outside. The downstream end of the out ball guide rail 8 communicates with a later-described relay box 37 provided outside the upstream portion of the storage tanks 9 and 10.
[0011]
In addition, storage tanks 9 and 10 are provided on both sides of the ball lifting device 5 below the pachinko island platform 1. The storage tanks 9 and 10 are formed so large that a large amount of pachinko balls are stored. Specifically, the number of pachinko balls stored in the storage portions 9a and 10a of the storage tanks 9 and 10 can sufficiently cope with various game states of the plurality of pachinko machines 2 installed on the pachinko islands 1. The size is designed (for example, 1 to 200,000 pieces each). The detailed structure of the storage tanks 9 and 10 will be described in detail later.
[0012]
An overflow box 11 for returning the pachinko balls overflowed from the upper tank 6 to the lower part is connected to the storage tanks 9 and 10 described above. The overflow box 11 is a rectangular parallelepiped box provided so as to use the adjacent space of the ball lifting device 5, and the inside thereof is partitioned in the vertical direction by the branch partition 12. The branch partition 12 is provided close to one side of the overflow box 11, and a plurality of descending plates are alternately provided in a step shape in a passage on one side communicating with the wide area to constitute a box priority passage 11a. The box non-priority passage 11b is configured by alternately providing a plurality of descending plates in a step shape in the passage on the other side communicating with the narrow region. That is, the pachinko balls overflowed from the upper tank 6 are preferentially guided to the box priority passage 11a, and overflow to the box non-priority passage 11b when the box priority passage 11a is full. The box priority passage 11a and the box non-priority passage 11b are respectively connected to the left storage tank 9 (hereinafter sometimes referred to as priority storage tank 9) and the right storage tank 10 (hereinafter referred to as priority storage tank 9) via a ball inlet 22b described later. It may communicate with the non-priority storage tank 10). Thus, in this embodiment, since the overflow mechanism is configured in a box shape instead of the conventional flexible pipe, it is possible to extremely reduce the generation of noise due to the recirculated pachinko balls and not only the recirculation function. Since there is also a storage function for storing a considerable amount of pachinko balls (about 2 to 30,000 in this embodiment), it is effective as a storage space inside the pachinko island platform 1 using a space that has not been used conventionally. Can be used.
[0013]
In addition, storage level detection sensors 13a to 13e and 14a to 14e for detecting the amount of stored balls are provided on the inner side walls of the storage tanks 9 and 10, respectively. According to the experiments by the present applicants, it was found that the change in storage of the pachinko balls in the storage tanks 9 and 10 is retained from the upstream side of the storage tanks 9 and 10. For this reason, the storage level detection sensors 13a to 13e and 14a to 14e are arranged in a substantially horizontal straight line, and the storage level detection sensors 13a and 14a disposed on the upstream sides of the storage tanks 9 and 10 can store the storage amount. While the lower limit is detected, the upper limit of the storage amount is detected by the storage level detection sensors 13e and 14e disposed on the downstream sides of the storage tanks 9 and 10. Based on the detection signals of these detection sensors 13a to 13e and 14a to 14e, the storage level notification device 15 attached to the outside of both ends of the pachinko island base 1 notifies the storage amount in the storage tanks 9 and 10. It has become.
[0014]
Next, the detailed structure of the storage tanks 9 and 10 will be described. First, the non-priority storage tank 10 will be described with reference to FIGS. As shown in FIG. 2, the non-priority storage tank 10 includes a pachinko ball storage unit 10 a by a rectangular parallelepiped tank base 17 installed in a lower space below the counter base 16, and the tank base Reference numeral 17 denotes a bottom plate 18, a connection bottom plate 19, a pair of left and right side wall plates 20, 21, a front wall plate 22, and a rear wall plate 23. The bottom plate 18 is provided so as to be inclined in the longitudinal direction from the rear wall plate 23 to the front wall plate 22 and in the width direction from the side wall plate 20 to the side wall plate 21, and the inclined lower end and the side wall plate in the width direction are provided. A connecting bottom plate 19 is attached between the base plate 21 and the base plate 18 along the inclination in the longitudinal direction of the bottom plate 18. On the upper surface of the connection bottom plate 19, a lower priority rod 24 and a ball guide path 25 are provided in two upper and lower stages. The lower priority rod 24 has a closed cross-sectional shape so that pachinko balls stored in the tank 10 do not enter, and the rear end portion is a ball introduction port formed in the rear wall plate 23 as shown in FIG. 23b. On the other hand, the ball guide path 25 is formed with intake ports 25a for taking in the pachinko balls stored in the tank 10 at the center and the rear end. In addition, in this embodiment, although the inlet 25a is provided in the total three places which consist of two places of the center part of the ball guide path 25, and one place of a rear-end part, it is not restricted to this, At least the ball guide path 25 In other words, the intake port 25a may be provided in the central portion or the rear end portion of the storage tank 10, in other words, in the midstream portion or the upstream portion of the storage tank 10. Further, the front end portion of the lower priority rod 24 is arranged at a position extending to the front wall plate 22 side than the front end portion of the ball guiding path 25. The front end portion of the connecting bottom plate 19 is connected to a ball outlet 22a formed in the front wall plate 22, and the ball outlet 22a is connected to an introduction rod 41 on the ball lifting device 5 side.
[0015]
Further, a T-shaped upper plate 26 is fixed to the upper portion of the side wall plates 20 and 21 and the front wall plate 22 forming the front end of the tank base 17 so as to be inclined downward toward the rear end side. The notch 26 a of the upper plate 26 that forms a T shape forms a through hole between the side wall plates 20, 21 and the front wall plate 22. A front end portion of the upper plate 26 is connected to a ball introduction port 22 b formed in the front wall plate 22. In addition, on the upper part of the inner surface of the side wall plates 20 and 21, flat plate-like conveying rods 27 and 28 that are inclined downward toward the rear end side are fixedly provided at predetermined intervals. Each of the conveying rods 27 and 28 is connected to the rear end portion of the upper plate 26 at each front end portion, and is arranged at a predetermined interval from the rear wall plate 23 at each rear end portion. At the center of the rear end portion of the upper plate 26, a branching projection 26b for projecting a pachinko ball flowing down on the plate 26 to the left and right conveying rods 27 and 28 is provided. Between each conveyance rod 27 and 28, an upper priority rod 29 having a U-shaped cross section that is inclined downward toward the rear end side is provided. The upper priority rod 29 has a front end arranged on the rear end side of the upper plate 26, and a rear end connected to the relay box 37 via a ball outlet 23 a formed in the rear wall plate 23. Yes. Note that the through hole formed by the cut portion 26a is configured so that when a pachinko ball is fed from the ball return device 3 and a pachinko ball is fed from the ball inlet 22b, By dropping a part of the ball as it is, clogging in the vicinity of the ball introduction port 22b is prevented.
[0016]
A pressure release plate 30 is fixed to the front end of the tank base 17 and below the upper plate 26 so as to be inclined downward toward the rear end. When a large amount of pachinko balls are stored in the tank 10, the pressure relief plate 30 distributes the pressure of the pachinko balls applied to the front end of the tank 10 (the lower end of the pachinko balls) and causes a smooth flow of the pachinko balls. It is supposed to be. Partition plates 31 to 34 are provided between the pressure release plate 30 and the bottom plate 18. The internal space partitioned by the partition plates 31 and 32 communicates with a ball introduction port 22c formed in the front wall plate 22, so that a pachinko ball transfer path 35 (see FIG. 3 is a solid line arrow). The space between the outside of the partition plates 31 and 32 and the partition plates 33 and 34 communicates with a ball introduction port 22d drilled in the front wall plate 22, so that a pachinko ball is fed from the ball introduction port 22d. Transfer path 36 (a dashed-dotted arrow in FIG. 3). A relay box 37 is provided on the outer surface of the rear wall plate 23 which is the rear end of the tank base 17. The relay box 37 is provided with a ball introduction port 37 a for connecting the out guide rail 8, and a pachinko ball from the out guide rail 8 or the upper priority rod 29 is used as a ball introduction port 23 b of the rear wall plate 23. Guide pieces 37b and 37c are provided for guiding to the guide. The relay box 37 has a function of temporarily storing the pachinko balls when the pachinko balls are sent from the out guide rail 8 to the upper priority basket 29 when the storage tank 10 is full.
[0017]
Thus, the non-priority storage tank 10 described above receives the return ball from the box non-priority passage 11b through the ball inlet 22b and also receives the return ball from the ball return device 3. Then, the reflux ball and the return ball are caused to flow down by the upper plate 26 and the conveying rods 27 and 28, respectively, and stored on the bottom plate 18 of the tank base 17, and this is transferred from the ball outlet port 22a to the ball feeding device 5 side. Derived to the introduction cage 41. When the flow rate of the pachinko balls flowing down the conveying rods 27 and 28 is large, a part of the pachinko balls is dropped directly onto the bottom plate 18 from the gap between the conveying rods 27 and 28 and the upper priority rod 29. In addition, pachinko balls derived from the ball outlet 22a after storage are derived via the pressure release plate 30 in the order of storage, those taken in through the intake 25a and derived from the ball guide path 25, There are two types. Thus, in this embodiment, the ball guide path 25 in which the intake port 25a is formed is provided in the storage tank 10, so that pachinko balls located upstream or downstream in the tank 10 are evenly fed. Can be sent to. For this reason, the pachinko balls do not stay in a certain portion of the storage tank 10 for a long period of time, and as a result, rusting of the pachinko balls associated with the stay can be prevented. Moreover, the non-priority storage tank 10 receives the used ball | bowl discharged | emitted from the ball | bowl discharge nozzle 7a of the said out ball box 7 via the upper priority ridge 29 (or the out guidance rail 8), as shown in FIG. Then, the used balls are transferred to the downstream end of the tank 9 via the relay box 37 and the lower priority rod 24, and are led out from the ball outlet 22a to the introduction rod 41 on the ball lifting device 5 side.
[0018]
Next, the structure of the priority storage tank 9 will be described with reference to FIG. In addition, since the priority storage tank 9 has substantially the same structure as the non-priority storage tank 10 described above, components having the same functions as those of the storage tank 10 are denoted by the same reference numerals and detailed description thereof. Is omitted. The priority storage tank 9 stores the reflux balls received from the box priority passage 11 a on the bottom plate 18 by flowing down with the upper plate 26 and the conveyance rods 27 and 28, and transfers them to the introduction rod 38. The pachinko balls transferred to the introduction rod 38 are sent to the ball introduction port 22d of the non-priority storage tank 10 by the lift of the mini lift 39. A ball guiding path 25 similar to that of the non-priority storage tank 10 is provided on the bottom plate 18 of the priority storage tank 9. Further, the priority storage tank 9 receives used balls from the pachinko machine 2 arranged in parallel through the upper priority rod 29 and the out guide rail 8. Then, the used balls are transferred to the bypass rail 40 via the relay box 37 and the lower priority rod 24, and are sent from the bypass rail 40 to the ball inlet 22c of the non-priority storage tank 10. In this way, the priority storage tank 9 does not lead the received pachinko ball directly to the ball lifting device 5 but sends it to the non-priority storage tank 10 via the mini-lift 39 or the bypass rail 40. That is, the pachinko island platform 1 of the present embodiment is configured such that the pachinko balls received in the storage tanks 9 and 10 are collectively led to the ball lifting device 5 from the ball outlet 22a on the storage tank 10 side.
[0019]
By the way, the storage tank 10 according to the present embodiment determines the priority order of the pachinko balls derived from the ball outlet 22a based on the structure near the ball outlet 22a (lower priority rod 24, transfer paths 35 and 36, etc.). is doing. Specifically, the derivation priority order of the pachinko balls is determined by the type of pachinko balls guided to the ball outlet 22a. The types of pachinko balls guided to the ball outlet 22a are the following four types (1) to (4).
(1) Pachinko balls stored on the bottom plate 18 of the non-priority storage tank 10, in other words, reflux balls and return balls sent into the non-priority storage tank 10. The pachinko balls of (1) are combined with those derived from the pressure release plate 30 in the order of storage described above and those derived from the ball guide path 25 by being taken in through the intake port 25a. It is a pachinko ball.
(2) Pachinko balls that flow down the lower priority basket 24 of the non-priority storage tank 10, in other words, used balls sent into the non-priority storage tank 10.
(3) Pachinko balls stored on the bottom plate 18 of the priority storage tank 9, in other words, reflux balls fed into the priority storage tank 9.
(4) Pachinko balls that flow down the lower priority basket 24 of the priority storage tank 9, in other words, used balls that are sent to the priority storage tank 9.
[0020]
Among these, the pachinko ball derived from the ball outlet 22a most preferentially is the (2) pachinko ball that is guided directly to the ball outlet 22a through the tank 10. The second is a pachinko ball (4) that is guided directly to the transfer path 35 in the tank 10 through the tank 9. The third is a pachinko ball (3) that is stored in the tank 9 and then led to the transfer path 36 in the tank 10 via the mini-lift 39. The fourth is a pachinko ball (1) that is stored in the tank 10 and then led to the ball outlet 22a via the pressure release plate 30 or the ball guide path 25. Further, the number of pachinko balls that the ball lifting device 5 lifts in 1 minute is set to 15000, and the pachinko that the mini lift 39 lifts in 1 minute (transfer from the priority storage tank 9 to the non-priority storage tank 10). When the number of balls is 10,000, the number of pachinko balls that are lifted per minute is approximately (1) 1000 pachinko balls, (2) 2000 pachinko balls, (3) There are 10,000 pachinko balls and 2000 (4) pachinko balls. That is, in the pachinko island stand 1 of this embodiment, about 4000 used balls ((2) and (4) pachinko balls) discharged per minute from a plurality of pachinko machines 2 arranged in parallel are given top priority. Next, about 10,000 reflux balls ((3) pachinko balls) transferred from the priority storage tank 9 to the non-priority storage tank 10 for 1 minute are then pumped up, and finally the non-priority storage tank 10 The remaining 1,000 balls are lifted from the recirculation balls and return balls ((1) pachinko balls) stored inside.
[0021]
As described above, the configuration of the storage tanks 9 and 10 according to the embodiment has been described. However, according to the present embodiment, the storage tanks 9 and 10 include the upper priority basket 29 that faces the lower end of the out ball box 7 and the upper part. A lower priority rod 24 having a closed cross-sectional shape for guiding the pachinko balls transferred from the priority rod 29 to the ball lifting device 5 is provided. By comprising in this way, even when a pachinko ball is discharged from the out ball box 7 in a state where a large amount of pachinko balls are stored in the storage tanks 9 and 10, the pachinko balls from the out ball box 7 are out balls. Without being piled up at the lower position of the box 7, it is preferentially sent to the ball lifting device 5 via the upper priority rod 29 and the lower priority rod 24. For this reason, it is possible to prevent clogging and ball overflow in the out ball box 7 caused by the stacking of pachinko balls at the lower position of the out ball box 7, and used balls from the out ball box 7. Thus, the pachinko balls can be smoothly circulated inside the pachinko island platform 1.
[0022]
In the storage tanks 9 and 10 of the above-described embodiment (first embodiment), all the pachinko balls discharged from the out ball box 7 are the upper priority rod 29 (and the out ball guide rail 8) having a U-shaped cross section. It is received and preferentially led out to the ball lifting device 5, but is not limited to this configuration. Hereinafter, other configurations will be described as a second embodiment with reference to FIGS. 5 to 8. However, this second embodiment is not an embodiment of the present invention, but a similar embodiment that can achieve the same object. The storage tank 50 of the second embodiment is composed of the same components as the storage tanks 9 and 10 of the first embodiment except for the upper priority trough 29. For this reason, in the following description, about the same component as 1st embodiment, while attaching | subjecting the same code | symbol, only a different structure from 1st embodiment is demonstrated. Further, since the configuration different from the first embodiment is the same in the left and right storage tanks, the right non-priority storage tank 50 will be described as an example. As shown in FIGS. 5 and 6, the storage tank 50 according to the second embodiment includes a flat upper priority rod 51 between the conveying rods 27 and 28. The upper priority rod 51 is disposed so as to be inclined downward toward the rear end side (upstream side) of the tank 50 with a predetermined distance from each of the transport rods 27 and 28, and the front end portion thereof is the rear end of the upper plate 26. On the other hand, the rear end portion communicates with the relay box 37 via a ball outlet 23 a formed in the rear wall plate 23. Further, the ball discharge nozzle 7a of the out ball box 7 arranged above the upper priority rod 51 is located in the gap between the upper priority rod 51 and the conveying rods 27 and 28 as shown in FIGS. Correspondingly arranged.
[0023]
Next, the rolling operation of the used balls by the upper priority rod 51 will be described. First, as shown in FIG. 7A, the pachinko balls stored in the tank 50 are relatively few, specifically, the upper end of the stored pachinko balls is higher than the upper priority basket 51 and the transport baskets 27 and 28. In the state positioned below, the used balls discharged from the ball discharge nozzle 7a fall directly into the storage section in the tank 50 through the gap between the upper priority basket 51 and the transport baskets 27 and 28. For this reason, in the state where the storage amount of the pachinko balls is small, the rolling operation of the used balls by the upper priority basket 51 is not performed. On the other hand, as shown in FIG. 7B, a state where a large amount of pachinko balls are stored in the tank 50, specifically, the upper end portion of the stored pachinko balls is the upper priority basket 51 and the transport baskets 27 and 28. In the state where the pachinko ball is positioned above the upper priority rod 51 and the conveying rods 27 and 28, the used balls from the ball discharge nozzle 7a are used as the upper priority rod 51 and the conveying rod 27. -It is bounced by the pachinko ball covering the gap with 28 to the upper priority rod 51 side, and flows down on the upper priority rod 51. That is, the pachinko ball rolling operation by the upper priority basket 51 is performed only in a state where the pachinko ball storage amount is large. As shown in FIG. 8, the used balls that have flowed down on the upper priority rod 51 once enter the relay box 37, and then are guided to the downstream end of the tank 50 through the lower priority rod 24.
[0024]
As described above, the upper priority basket 51 according to the second embodiment preferentially rolls the used balls discharged from the out ball box 7 when the amount of pachinko balls stored in the tank 50 is large. It is guided to the downstream end (ball outlet 22a) of the tank 50. Therefore, even when the pachinko balls are discharged from the out ball box 7 in a state where a large amount of pachinko balls are stored in the storage tank 50, the pachinko balls from the out ball box 7 are piled up at a position below the out ball box 7. It is preferentially sent to the ball lifting device 5 without any problem. For this reason, it is possible to prevent clogging and ball overflow in the out ball box 7 caused by the stacking of pachinko balls at the lower position of the out ball box 7, and used balls from the out ball box 7. Thus, the pachinko balls can be smoothly circulated inside the pachinko island platform 1.
[0025]
The relationship between the upper priority basket 51 and the ball discharge nozzle 7a of the out ball box 7 is that the used balls from the out ball box 7 roll when the amount of pachinko balls stored in the tank 50 is small. Without being dropped, the storage unit 50a is dropped as it is. For this reason, with respect to a phenomenon in which the stored balls are biased and reduced at the intake port 25a of the ball guide path 25 provided for preventing rust of the stored balls, the decreased portion is used as a used ball from the out ball box 7 Can be supplemented with. Accordingly, even when the storage level detection sensors 13a to 13e and 14a to 14e (ball amount detection means) detect the amount of the pachinko balls stored, since there is no decrease in the bias of the storage balls, the pachinko balls in the tank 50 are appropriately stored and managed. can do. In addition, in the structure which compensates for such an uneven decrease part of the storage ball with a used ball, the lower end of the out ball box 7 (the ball discharge nozzle 7a) is located substantially above the intake port 25a (the decrease decrease position of the storage ball). By adopting this configuration, the used balls from the ball discharge nozzle 7a can more reliably compensate for the portion where the deviation of the stored balls is reduced.

In addition, there are the following as inventions that can be grasped from the embodiment described above.
(1) The storage tank is composed of a left storage tank disposed on the left side of the ball lifting device and a right storage tank disposed on the right side of the ball lifting device. The pachinko balls sent to one of the storage tanks (priority storage tank 9) are sent to the other storage tank (non-priority storage tank 10), and the pachinko balls are collectively sent from this other storage tank to the ball lifting device. Is derived. By configuring in this way, even when a pair of storage tanks are provided on the left and right sides of the ball lifting device to circulate a larger amount of pachinko balls inside the pachinko island platform, the pachinko to the ball lifting device It is possible to clarify the prioritization order of balls, and as a result, smooth pachinko balls can be circulated on the pachinko islands.

【The invention's effect】
As is apparent from the above description, in the configuration according to claim 1 of the present invention, in the pachinko island platform in which a plurality of pachinko machines are arranged side by side and the pachinko balls used in the pachinko machines are used cyclically. An out ball box for counting used pachinko balls discharged from the pachinko machine, and a lower position of the out ball box provided corresponding to some of the plurality of pachinko machines. A storage tank that stores the pachinko balls in the storage unit, and a ball lifting device that transports the pachinko balls stored in the storage tank and supplies the pachinko balls to the pachinko machine, and the storage tank includes the storage tank An upper priority basket arranged at an inclination from one end to the other end at the upper part of the tank and facing the lower end of an out ball box provided corresponding to the part of the pachinko machines; A lower priority basket that is arranged in an inclined manner from the other end to the inlet of the ball lifting device on the bottom surface of the storage tank, and that does not receive pachinko balls stored in the storage unit, The pachinko ball discharged from the out ball box provided corresponding to the pachinko machine is directly received by the upper priority rod without being stored in the storage portion, and is guided from the upper priority rod to the lower priority rod and the ball lifting It is characterized by preferentially guiding to the device. By configuring in this way, even when a large amount of pachinko balls are stored in the storage tank, even if the pachinko balls are discharged from the out ball box, the pachinko balls from the out ball box are at the lower position of the out ball box. It is preferentially sent to the ball lifting device without being piled up. For this reason, it is possible to prevent clogging and overflowing in the out ball box caused by stacking pachinko balls in the lower position of the out ball box, and counting used balls by the out ball box The pachinko balls can be smoothly circulated inside the pachinko islands.
