Description

The present invention relates to a ball exchange device between pachinko islands that exchanges balls according to the amount of balls stored on a plurality of pachinko islands.

Conventionally, between a plurality of pachinko islands installed in a game arcade, balls were exchanged by a ball exchange device according to the amount of balls stored in the pachinko island. This ball exchange was performed only between adjacent pachinko islands.

However, when ball exchange is performed only between adjacent pachinko islands, for example, when the ball storage amount of a certain pachinko island reaches the lower limit, return to the ball return device of the adjacent pachinko island is prohibited. At the same time, the ball will be replenished from the adjacent pachinko island, but if the amount of ball storage on the adjacent pachinko island is not so large, the adjacent pachinko island will immediately reach the lower limit and be further adjacent to pachinko island. There is a disadvantage that the return to the ball return device must be prohibited and the resupply must be similarly performed from the adjacent pachinko island stand, which prohibits the return to the ball return device as a whole.

Conversely, when the storage amount of balls on a certain pachinko island has reached the upper limit, return to the ball return device of that pachinko island is prohibited, and balls must be moved only to the adjacent pachinko island. However, if a large amount of balls are already stored on the adjacent pachinko island, the adjacent pachinko island also immediately reaches the upper limit, and return to the ball return device of the pachinko island is prohibited and further adjacent. The ball must be moved to the pachinko island stand, and there is a disadvantage that the period during which the return to the ball return device is prohibited is prolonged as a whole.

The present invention has been made in view of the above-described circumstances, and an object of the present invention is to provide a pachinko island stand capable of constantly equalizing the storage amount of balls on the pachinko island stand and quickly responding to a decrease in the storage amount. A ball exchange device is provided.

One example of a solution adopted by the invention according to claim 1 to achieve the above object will be described with reference to the drawings. As shown in FIG. 19, FIG. 20, FIG. 27, and FIG. In the ball interchange device between pachinko islands that exchanges balls in accordance with each ball storage amount of the table 1, in step 97, the sensor S1 determines that the ball storage amount of one pachinko island table A has reached the lower limit. Then, in steps 141 to 144, the closest pachinko island C among the pachinko islands having a predetermined ball storage amount or more is specified from the plurality of pachinko islands in an exchange relationship, and the identification is performed in steps 152 and 153. The ball exchange device of the pachinko islands A to C located therebetween is controlled so that the ball moves from the pachinko island stand C to the pachinko island stand A that has reached the lower limit.

Further, in the invention of claim 2, as shown in FIGS. 19, 20, and 27 to 32, the ball moves from the specified pachinko island stand C to the pachinko island stand A which has reached the lower limit. In step 160 to 173, the amount of the moved ball is controlled and controlled when the ball exchange devices of the pachinko islands A to C are controlled (steps 160 to 173). When it is determined by the sensor S3 that the storage amount has returned to the predetermined ball storage amount, the number of balls calculated and stored in the specified pachinko island stand C from the pachinko island stand A that has reached the lower limit in Steps 180 to 189. The present invention is characterized in that the ball AC devices of the pachinko islands A to C located therebetween are controlled so as to move.

According to the third aspect of the present invention, as shown in FIGS. 1, 2, 7 and 8, the ball exchange device is lifted by a ball lifting device 5 installed on the pachinko island stand 1. Between the adjacent AC tanks 7, 7, an AC upper gutter 70 sloping toward the center at an upper portion between the adjacent AC tanks 7, 7. The AC lower arch gutter 71, whose upper center is connected and abutted so that the balls flowing down the lower center of the AC upper gutter 70 and crossing the inside thereof are guided in a cross shape, and the AC tank 7 A stopper device 61 provided at a connection portion with the AC upper gutter 70 and driven to a closed state for preventing the inflow of balls into the AC upper gutter 70 and an open state for allowing the ball to flow. Is controlled by the stopper device 61 It is characterized in that is to open and close drive control.

Further, in the invention of claim 4, as shown in FIGS. 1 and 9, the AC lower gutter is inserted into a lower portion between the adjacent AC tanks and flows down at the lower center of the AC upper gutter. An arc-shaped lower arch gutter 71 is formed in an arch shape in which the upper center is connected and abuts so that the ball to be guided is crossed.

With the configuration according to the first aspect of the present invention, since it is possible to move from the pachinko island table C having the storage amount equal to or more than the predetermined amount to the pachinko island table A where the ball storage amount has reached the lower limit, each pachinko island table can be moved. The amount of increase or decrease in the amount of stored balls can be reduced to achieve an even amount of storage, and it is possible to respond promptly to a decrease in the amount of stored balls.As a result, the time during which return to the entire ball return device is prohibited is shortened. can do.

With the configuration according to the second aspect of the present invention, the pachinko island stand A, which has reached the lower limit at first, recovers the ball storage amount by the moved AC ball, which is not enough with its own stored ball, but is returned by the customer. Depending on the ball, there is a possibility that the ball will eventually be stored more than the initial ball storage amount.To prevent this, the pachinko island that replenished the number of balls replenished during business hours when the stored amount returned to the predetermined value By returning to the platform C, the storage amounts of all pachinko island platforms can be quickly equalized with the initial values.

According to the third aspect of the present invention, the movement of the AC ball can be performed under natural flow, so that the number of AC balls per unit time can be increased.

With the configuration according to the invention of claim 4, the AC upper gutter 70 is supported from below by the arch structure of the AC lower arch gutter 71 formed in an arch shape, and sufficient strength can be secured. Even if a pachinko ball stays in the gutter 70 and the AC lower arch gutter 71, it is not twisted or bent by its weight. Therefore, unlike the conventional case, there is no need to support the AC gutter with a separately prepared supporting member, so that the structure is simple and the appearance is preferable.

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 FIGS. FIG. 1 is a perspective view showing a relationship between a plurality of pachinko island stands 1 and FIG. 2 is a longitudinal sectional view showing an internal structure of one pachinko island stand 1.

As shown in FIG. 2, the pachinko island stand 1 has a rectangular parallelepiped frame structure, and the pachinko machine 2 is arranged at the center in the longitudinal side of the pachinko machine 2 in a back-facing manner. Further, on the pachinko island stand 1, a ball returning device 3 for returning the pachinko balls obtained by the pachinko machine 2 is provided in one side of the pachinko machine storage unit 4 in the center thereof in parallel with the pachinko machine 2. However, it is desirable that the ball return device 3 be provided on the row side of the pachinko machine 2 in which the later-described non-priority storage tank 12 is built. This is because it is possible to reliably return the prize balls from the ball returning device 3 to the non-priority storage tank 12 which is almost not full in the normal business state. A return port is formed in the ball return device 3, and the pachinko balls (prize balls) returned from the return port are guided onto an upper gutter 21 described later. Further, although not shown, the return opening of the ball return device 3 is driven to open and close by an electric drive source (for example, a motor or a solenoid).

玉 Further, a doffing and feeding device storage unit 4 is formed substantially at the center of the pachinko island stand 1, and a doffing and feeding device 5 is stored and installed in the doffing and feeding device storage unit 4. The ball-lifting device 5 according to the present embodiment lifts pachinko balls by a belt-shaped transport belt (not shown in detail), and the belt-shaped transport belt is installed vertically with respect to the pachinko island stand 1. The pachinko balls are then transported to the top. An upper tank 6 for temporarily storing the pumped pachinko balls is provided above the ball pumping device 5. From the upper tank 6, supply gutters (not shown) are provided on the left and right in an inclined manner so that pachinko balls flow down from the upper tank 6. This supply gutter is provided with a distribution chute (not shown) corresponding to each pachinko machine 2 so as to take in pachinko balls flowing down the supply gutter. The pachinko balls taken in by the distribution chute are counted by a counting device (not shown) provided at the lower part of the distribution chute, and then supplied to a prize ball tank (not shown) provided at an upper part on the back of the pachinko machine 2 to be played. Used as a prize ball paid out to players. Although FIG. 2 illustrates the pachinko island stand 1 not provided with a betting machine, the case where the betting machine is provided so as to be sandwiched between the pachinko machines 2 is shown. Is provided with a distribution chute so as to correspond also to this tama ball lending machine. In this case, an independent distribution chute may be provided corresponding to the vending machine, or a distribution chute that divides the pachinko machine 2 and the vending machine with one distribution chute may be used.

(1) As shown in FIG. 1 and FIG. 2, the upper tank 6 is provided with an AC tank 7 that constitutes a ball AC device inserted between the plurality of pachinko island stands 1 so as to communicate with each other. The ball exchange device comprises an AC tank 7, an AC upper gutter gently connected from the AC tank 7 to the AC tank 7 of the adjacent pachinko island 1, and an AC tank 7 of the adjacent pachinko island 1. And an arc-shaped lower AC arch gutter 71 for receiving the AC ball from the lower part of the AC tank 7. The above-mentioned upper tank 6 and AC tank 7 are covered with a cover body 8, but this cover body 8 is desirably detachably mounted. The ball AC device including the upper tank 6 and the AC tank 7 will be described later in detail.

On the other hand, storage tanks 11 and 12 are provided on the lower side of the pachinko island stand 1 and on both sides of the doffing and conveying device 5. The storage tanks 11 and 12 are formed larger as a larger amount of pachinko balls are stored. Specifically, the number of pachinko balls stored in the storage sections of the storage tanks 11 and 12 is such that the number of pachinko machines 2 installed on the pachinko island stand 1 can sufficiently cope with various gaming states (for example, (150,000 to 200,000 each).

Thus, the used balls discharged from each pachinko machine 2 are discharged downward from a ball discharge nozzle (not shown) of the out-ball box 9 having a counting function. In the pachinko machine 2 at a position facing the storage tanks 11, 12, the ball discharge nozzle is inclined downward from the downstream end (to the center of the island) toward the upstream end at the center of the storage tanks 11, 12. In the pachinko machine 2 which is disposed facing the out ball guiding inner gutter 13 provided and deviates from the storage tanks 11 and 12, the out ball guiding gutter 10 which is inclined downward from the island end toward the storage tanks 11 and 12 is provided. It is arranged to face. The out ball guiding gutter 10 is connected to a merging box 14 attached to the outside of the upstream end side walls of the storage tanks 11 and 12, and the out ball guiding inner gutter 13 is also connected to the merging box 14. 14 is connected to an out ball guiding / merging gutter 15 which is arranged along the lower part of one side wall of the storage tanks 11 and 12 toward the introduction gutter 18 of the ball lifting / feeding device 5. Therefore, the used balls discharged from each pachinko machine 2 are passed through the out ball guiding inner gutter 13 or the out ball guiding gutter 10, the merging box 14, and the out ball guiding merging gutter 15 to the inlet portion of the ball lifting device 5. Is given priority. However, the left and right storage tanks 11 and 12 have slightly different structures depending on the arrangement of the doffing and conveying device 5 as described later, which will be described in detail later.

The storage tanks 11 and 12 are connected to an overflow box 22 for returning the pachinko balls overflowing from the upper tank 6 and the AC balls flowing from the AC tank 7 to the lower part. The overflow box 22 is a rectangular parallelepiped box provided so as to use the space adjacent to the doffing and conveying device 5, and the inside thereof is vertically partitioned by a branch partition 23. This branching partition 23 is provided close to one side of the overflow box 22 and forms a box priority passage 22a by alternately providing a plurality of flow-down plates in a stepped manner in a passage on one side communicating with the wide area thereof, A plurality of flow-down plates are alternately provided in steps on the other side of the passage that communicates with the narrow region to constitute the box non-priority passage 22b.

Thus, the pachinko balls overflowing from the upper tank 6 and the AC balls flowing from the AC tank 7 are preferentially guided to the box priority passage 22a, and when the box priority passage 22a becomes full, the box non-priority passage 22b It is overflowing. The box priority passage 22a and the box non-priority passage 22b are connected to the left storage tank 11 (hereinafter, may be referred to as a priority storage tank 11) and the right storage tank 12 (hereinafter, may be referred to as a non-priority storage tank 12). It is designed to communicate with As described above, in the present embodiment, since the overflow mechanism is configured in a box shape instead of the conventional flexible pipe, the generation of noise due to the returned pachinko balls can be extremely reduced, and not only the return function but also the return function is provided. Since there is also a storage function for storing a considerable amount of pachinko balls (in the present embodiment, about 20 to 30,000 pieces), a space that has not been used conventionally can be effectively used as a storage space inside the pachinko island stand 1. Available. In FIG. 2, the overflow box 22 is drawn in front of the doffing and feeding device 5, but this is to show the structure of the overflow box 22 in detail. , And is formed more deeply than the doffing and feeding device 5.

Further, on the inner side walls of the storage tanks 11 and 12, a plurality of storage level detection sensors S1 to S5 (see FIG. 10) for detecting the amount of stored balls are provided. According to the experiments performed by the present applicants, it has been found that the change in the storage of the pachinko balls in the storage tanks 11 and 12 is such that the change is stored from the upstream side of each of the storage tanks 11 and 12. For this reason, the storage level detection sensors S1 to S5 are arranged in a substantially horizontal straight line, and the storage level detection sensor S1 disposed upstream of the priority storage tank 11 detects the lower limit of the storage amount, while the storage level detection sensors S1 to S5 are non-priority. The storage level detection sensor S5 arranged downstream of the storage tank 12 detects the upper limit of the storage amount. Based on the detection signals of the detection sensors S1 to S5, a storage level indicator 24 attached to the outside of both ends of the pachinko island stand 1 notifies the storage amount in the storage tanks 11 and 12, and The opening / closing control of the stopper device 61 of the ball exchange device is performed to equalize the amount of stored balls in the plurality of pachinko islands 1.

Here, the detailed structure of the storage tanks 11 and 12 will be described with reference to FIG. Although the priority storage tank 11 and the non-priority storage tank 12 have slightly different structures, the same reference numerals are given to components having the same function. The storage tanks 11 and 12 cause the balls received from the overflow box 22 to flow down by the upper gutter 21 and sequentially store the balls from the upstream side on the bottom surface inclined toward the ball discharging device 5, and doff the stored balls. It leads to the introduction gutter 18 of the feeding device 5. However, the balls stored in the priority storage tank 11 are placed on the bottom surface of the priority storage tank 11 because the introduction gutter 18 of the ball lifting and conveying device 5 is arranged in a direction facing the bottom surface of the non-priority storage tank 12. It is guided to the small lifting device 20 from the communicating lower connecting gutter 19 and supplied to the non-priority storage tank 12 by the small lifting device 20.

Further, in the priority storage tank 11, an out-ball guiding inner gutter 13 for receiving a used ball from the pachinko machine 2 arranged substantially at the center as described above is formed. Out balls that flow down 13 and the out ball guiding gutter 10 are transferred to the connecting gutter 16 via the merging box 14 and the out ball guiding merging gutter 15, and are sent from the connecting gutter 16 to the non-priority storage tank 12. In this manner, the priority storage tank 11 sends the received pachinko balls to the non-priority storage tank 12 via the small lifting device 20 or the communication gutter 16 instead of directly leading out the pachinko balls to the doffing and feeding device 5. That is, in the pachinko island stand 1 of the present embodiment, the pachinko balls received in the storage tanks 11 and 12 are collectively guided from the storage tank 12 side to the ball-lifting and conveying device 5. This is because the introduction gutter 18 of the doffing device 5 is directed only toward one storage tank 12 because the inflow of the balls into the doffing device 5 is made smooth and the lifting capability of the doffing device 5 is improved. The reason for this is to allow the pachinko island stand 1 to be formed so that the island width is reduced, as well as to sufficiently exert the effect.

Further, in the priority storage tank 11, the reason why the two upper and lower communication gutters connected to the non-priority storage tank 12 are provided is that the communication gutter 16 connected to the upper out ball guiding / merging gutter 15 is used and becomes dirty. In order to preferentially guide the pachinko balls to the ball-lifting device 5 without storing them in the priority storage tank 11, the pachinko balls need to be provided at a relatively high position, specifically, a position higher than the bottom surface of the non-priority storage tank 12. There is. Otherwise, the out balls that flow down the out ball guide merging gutter 15 cannot naturally flow down to the non-priority storage tank 12 side. On the other hand, if the bottom surface of the priority storage tank 11 is matched with the height position of the out ball merging gutter 15, the pachinko balls stored in the priority storage tank 11 also naturally flow down to the non-priority storage tank 12 via the communication gutter 16. However, since the position of the bottom surface is increased, the storage amount in the priority storage tank 11 is reduced accordingly. For this reason, the height position of the bottom surface of the priority storage tank 11 is lowered to increase the storage amount, and the lower communication gutter 19 communicating with the bottom surface is connected to the small lifting device 20, and the non-priority is controlled by the small lifting device 20. It is sent to the storage tank 12.

A storage ball guide gutter 17 is provided on one side of the bottom surface of the priority storage tank 11. The storage ball guiding gutter 17 is a pachinko ball stored in the priority storage tank 11 and takes in the ball stored in an upstream portion or a middle portion thereof and guides the ball to the downstream side. The function of uniformly guiding the pachinko balls stored in the priority storage tank 11 to the lower connecting gutter 19 so that the pachinko balls do not stay in one place is exhibited. Similarly, a storage ball guiding gutter 17 is also provided on the bottom surface of the non-priority storage tank 12 so that the pachinko balls stored in the non-priority storage tank 12 are uniformly guided to the introduction gutter 18. However, on the upper part of the storage ball guiding gutter 17 provided on the non-priority storage tank 12 side, the out ball guiding merging gutter 15 is provided in an overlapping manner, and the outlet of the out ball guiding merging gutter 15 is stored at the outlet. Since the outlet gutter 17 is closer to the introduction gutter 18 than the outlet of the ball gutter 17, the outgoing ball discharged from the outball guiding merging gutter 15 covers the ball flowing out of the storage ball guiding gutter 17 in front of the upper part of the ball, and the storage ball guiding gutter 17 Since the ball is stopped, the out ball flowing down the out ball guiding / merging gutter 15 is preferentially guided to the introduction gutter 18.

In the present embodiment, the priorities of the pachinko balls guided to the introduction gutter 18 are as follows. First, the types of pachinko balls guided to the introduction gutter 18 are the following four types (1) to (4).
(1) Pachinko balls stored on the bottom plate of the non-priority storage tank 12.
(2) Pachinko balls that flow down the out ball guide merging gutter 15 of the non-priority storage tank 12.
(3) Pachinko balls stored on the bottom surface of the priority storage tank 11 and sent to the non-priority storage tank 12 by the small lifting device 20.
(4) Pachinko balls sent down to the non-priority storage tank 12 by the connecting gutter 16 flowing down the out ball guide merging gutter 15 of the priority storage tank 11.

う ち Of these, the pachinko balls that are introduced into the introduction gutter 18 most preferentially are the pachinko balls (2) that are guided directly to the introduction gutter 18 through the non-priority storage tank 12. The second is a pachinko ball (4) that is guided from the inside of the priority storage tank 11 to the non-priority storage tank 12 through the communication gutter 16. The third is the pachinko ball (3) which is stored in the priority storage tank 11 and then guided into the non-priority storage tank 12 via the small-sized lifting device 20. The fourth is the pachinko ball (1) stored in the non-priority storage tank 12.

玉 In addition, the doffing apparatus 5 in the present embodiment has a capacity of 15,000 pieces / min as its lifting capacity, and the small-size frying apparatus 20 has a capacity of 10,000 pieces / min. Under the premise that there is such a lifting capability, the following will be described in consideration of how the balls (1) to (4) are distributed. That is, since the average number of the pachinko machines 2 installed on the pachinko island stand 1 is about 40 in total, the maximum number of balls of (2) and (4) is 4000 / min, and (3) Of pachinko balls is 10,000 / min. Therefore, the number of pachinko balls of (1) is 1000 pieces / min. That is, in the pachinko island stand 1 of the present embodiment, approximately 4000 used balls (pachinko balls of (2) and (4)) discharged from the plurality of pachinko machines 2 arranged in one minute are the highest priority. Then, about 10,000 return balls (pachinko balls of (3)) transferred from the priority storage tank 11 to the non-priority storage tank 12 in one minute, and finally the non-priority storage tank 12 The remaining about 1,000 pieces are returned from the recirculation balls and the return balls (the pachinko balls of (1)) stored therein.

As described above, the outline of the pachinko island stand 1 according to the embodiment has been described. However, as described above, the pachinko island stand 1 according to the present embodiment has a ball exchange device inserted between adjacent pachinko island stands 1. I have. Therefore, a detailed structure of the ball exchange device will be described below with reference to FIGS. FIG. 3 is a perspective view showing the relationship between the upper tank 6 and the AC tank 7, FIG. 4 is a perspective view showing the internal structure of the upper tank 6, and FIG. FIG. 6 is a perspective view showing the flow of balls in the upper tank 6 and the AC tank 7, and FIG. 7 shows the relationship between the AC tank 7 and the AC upper gutter 70 and the AC lower arch gutter 71. 8 is a cross-sectional view of an intersection between an AC upper gutter 70 and an AC lower arch gutter 71, and FIG. 9 is a cross-sectional view of the pachinko island stand 1 showing a different embodiment of the ball AC device. It is a perspective view.

As described above, the ball AC device includes an AC tank 7, an AC upper gutter 70 gently and inclinedly connected from the AC tank 7 to the AC tank 7 of the adjacent pachinko island stand 1, and an adjacent pachinko island stand 1. An AC-shaped lower arch gutter 71 for receiving an AC ball from the AC tank 7 into the lower portion of the AC tank 7. First, the AC tank 7 and an upper tank 6 closely related to the AC tank 7. Will be described with reference to FIGS.

As shown in FIGS. 3, 4 and 6, the upper tank 6 is formed in a box shape having a ball inlet 30 formed on one upper side thereof for receiving the balls discharged by the ball discharging device 5. The inside thereof is branched into a branch space 31 and an overflow space 32 by a branch vertical plate 33. The diversion space 31 is a space into which the pachinko balls flowing in from the ball inlet 30 enter first, and the pachinko balls entering the diversion space 31 are stepped plates 34 to 36 provided so as to be inclined inward alternately. As a result, the water drops downward while the momentum is weakened, and is guided from the stepped bottom plate 37 constituting the bottom surface of the branch flow space 31 to the supply outlet 38 opened on one side wall of the upper tank 6. The supply outlet 38 is connected to a supply gutter (not shown) for supplying balls to the pachinko machine 2 and the machine between the pachinko machines, which are arranged one side (right side in FIG. 2) from the center of the pachinko island stand 1. Things.

In addition, a lower guide side plate 39 that is inclined toward the other side wall of the upper tank 6 is provided on the branch vertical plate 33 side of the step plate 36 provided above the stepped bottom plate 37. A supply port 48 is provided at a position corresponding to the tip. The supply connection port 48 is connected to the supply connection cylinder 41 that is inserted between the supply tank 48 and the AC tank 7. The downstream end of the supply connection cylinder 41 is connected to a receiving port 55 of the AC tank 7, and the receiving port 55 and a supply outlet 58 described later are communicated. The supply outlet 58 is connected to a supply gutter (not shown) for supplying balls to the pachinko machine 2 and the machine for renting pachinko balls, which are arranged on the other side (left side in FIG. 2) from the center of the pachinko island stand 1. Things.

An upper guide side plate 40 inclined toward the other side wall of the upper tank 6 is provided on the branch vertical plate 33 side of the uppermost step plate 34, and is provided at a position corresponding to the tip of the upper guide side plate 40. An exchange contact 49 is established. The AC communication tube 49 is connected to the AC communication port 49 and is connected to the AC tank 7. A stopper plate 40a is fixed immediately before the AC communication port 49 of the upper guiding side plate 40. The stopper plate 40a is a ball flowing from the ball inlet 30 and traveling along the step plate 34 and the upper guiding side plate 40. The ball is guided to the lower portion so that the ball does not flow out of the AC communication port 49, and only the ball overflowing to the upper guide side plate 40 flows out to the AC communication port 49.

On the other hand, the upper end of the branch vertical plate 33 is located slightly above the above-described upper guide side plate 40, and the overflow space 32 branched by the branch vertical plate 33 also has a step plate 43 which is alternately inclined inward. To 46 are provided. The step plates 43 to 46 are for guiding the ball overflowing from the upper end of the branch vertical plate 33 downward while weakening the momentum of the ball. The lowermost step plate 46 projects forward and forms the bottom surface of the overflow guide gutter 47. ing. The lower end of the overflow guide gutter 47 communicates with the box priority passage 22 a of the overflow box 22. Note that members (rubber, synthetic resin, or the like) for reducing the impact of the falling ball are attached to the upper surfaces of the step plates 43 to 45 provided in the overflow space 32. It may be affixed to the step plates 34 to 36 or the stepped bottom plate 37 provided.

In the upper tank 6 configured as described above, the pachinko balls pumped by the ball pumping device 5 are guided from the ball inlet 30 to the diverting space 31, and thereafter, the step plates 34 to 36 and the step-like bottom plate 37. From the supply outlet 38 with the highest priority. Since the number of pachinko balls used in the supply gutter on one side is far greater than the number of pachinko balls used by the ball lifting device 5, the balls flowing into the diversion space 31 are immediately stored and accumulated, The accumulated ball first flows out from the middle step plate 36 and the lower guiding side plate 39 to the replenishment connection port 48, and as described above, from the replenishment outlet 58 via the replenishment connection cylinder 41 and the AC tank 7, the other side. Supply gutter. Since the number of pachinko balls to be pumped is much larger than the number of pachinko balls used in the left and right supply gutters described above, the diversion space 31 further accumulates pachinko balls. It is led to the AC tank 7 by being guided to the upper guide side plate 40 and the stopper plate 40a. The balls guided to the AC tank 7 are supplied to the adjacent pachinko island 1 through an AC upper gutter 70 as described later. In this case, the maximum number is 6,000 pieces / minute (the number is 3000 pieces / minute for only one AC upper gutter 70, but there are two on the left and right sides). Therefore, since the number of pumping is larger than the sum of the number of supply troughs to the left and right supply gutters and the AC tank 7, the number of pachinko balls further accumulates in the diversion space 31, and the accumulated balls are It jumps over the upper end of the branch vertical plate 33, flows out into the overflow space 32, and is guided from the overflow guide gutter 47 to the overflow box 22.

In other words, in the present embodiment, as long as the ball discharging device 5 is discharging balls at a normal discharging capacity (15000 pieces / min), the supply to the left and right supply gutters and the AC tank 7 is the maximum value. Even in the reached state, the balls are constantly circulated by being guided from the overflow space 32 to the overflow box 22.

On the other hand, as shown in FIGS. 3, 5, 6, and 7, the AC tank 7 communicated with the upper tank 6 is a branch horizontal plate provided in a horizontal direction slightly above the substantially center of a rectangular parallelepiped box. A supply space 50 and a supply space 51 are branched by 52, and a reception port 53 and a supply port 54 are opened so as to face the supply space 50. The receiving port 53 is connected to the downstream end of the AC communication tube 42, and the feed port 54 is formed on each of the left and right side walls adjacent to the side wall on which the receiving port 53 is formed. , To which the upstream end of an AC upper gutter 70 described later is connected. Thus, a passage for guiding the pachinko balls received from the receiving port 53 to the feeding port 54 is formed in the feeding space 50, and the path is provided with a passage forming plate 50a (see FIG. 5). It is formed by doing. The AC upper gutter 70 is connected to the outside of the feed port 54 as described above, and a stopper device 61 is attached between the feed port 54 and the AC upper gutter 70. As shown in FIG. 3, the stopper device 61 includes a motor 62, an elevating plate 63 that is moved up and down by the motor 62, and a guide piece 64 that guides the operation of the elevating plate 63. The stopper device 61 is based on the signals from the ball amount sensors S1 to S5 provided in the storage tanks 11 and 12 of the own island and the ball amount sensors S1 to S5 provided in the storage tanks 11 and 12 of the other islands. Opening / closing drive is controlled. This will be described in detail later.

The receiving space 51 is provided with a receiving port 55, a supply port 58, and a receiving port 59. The receiving port 55 is connected to the downstream end of the replenishing connecting cylinder 41, and has a replenishing port 58 formed in a lower part of the side wall facing the receiving port 55. A pair of partition plates 56 are erected in the receiving space 51 so as to connect the receiving port 55 and the replenishing outlet 58, and guide the pachinko balls received from the receiving port 55 only to the replenishing outlet 58. ing. In the space formed by the pair of partition plates 56, an inclined bottom surface 57 is provided on the bottom surface of the space, which is inclined downward toward the supply outlet 58, and a step plate 57a is provided on the upper portion of the supply outlet 58 in a reversely inclined shape. The pachinko ball received from the receiving port 55 is temporarily received by the step plate 57 a to reduce the momentum, and then discharged from the replenishing outlet 58 by the inclined bottom surface 57. The receiving port 59 faces the space outside the pair of partition plates 56. The end of the AC lower arch gutter 71 is connected and fixed to the outside of the receiving port 59, and the pachinko balls received from the AC lower arch gutter 71 are received in the outer space of the partition plate 56, and then constitute the bottom surface. It is discharged to the outside of the AC box 7 from a drop port 60a formed in the center of the bottom plate 60. The pachinko balls discharged from the falling port 60a are guided to a box priority passage 22a of the overflow box 22, as shown in FIG.

The configuration of the upper tank 6 and the AC tank 7 has substantially the above-described configuration. Next, an AC upper gutter 70 and an AC lower arch gutter 71 to be inserted into the AC tank 7 will be described with reference to FIGS. This will be described with reference to One end of the AC upper gutter 70 is connected and fixed to the feed port 54 of the AC tank 7, and the other end of the AC upper gutter 70 is gently inclined toward substantially the center between the adjacent pachinko island stands 1, and is downwardly directed to the tip. AC lower opening 73 is formed. Therefore, the AC upper gutter 70 is fixedly extended from the AC tank 7 of the adjacent pachinko island stand 1, respectively. On the other hand, the AC lower arch gutter 71 is constituted by a single arc-shaped gutter whose both ends are connected and fixed to the receiving port 59 of the adjacent AC tank 7, and an AC upper opening 74 is formed at the top of the arc. Have been. The AC upper opening 74 and the AC lower opening 73 communicate face-to-face with each other so as to guide the pachinko balls flowing down in an intersecting manner. In order to securely connect the AC upper opening 74 and the AC lower opening 73, a connector 75 that wraps and fixes the outer peripheries of the two AC upper gutters 70 and the AC lower arch gutter 71 is fixed. The AC upper gutter 70 and the AC lower arch gutter 71 are made of a metal gutter member having a U-shaped cross section with an open upper surface and a material such as semi-rigid urethane adhered to the inner periphery of a soft urethane. By covering the lid cover plate to which the material is adhered from the upper surface, the lid cover plate is configured as a cylindrical material having a rectangular cross section as a whole, and exhibits a noise reduction effect. Further, a sensor 72 is provided at the lower end of the AC lower arch gutter 71 (immediately before the receiving port 59), and the sensor 72 monitors the flowing state of the AC ball, the failure of the stopper device 61, and the like. Note that rubber or a synthetic resin may be attached below each urethane material to improve the vibration absorption.

As described above, the configuration of the pachinko island stand 1 according to the embodiment has been described. However, in the cover body 8 that covers the upper tank 6 and the AC tank 7 in the above-described embodiment, the AC upper gutter 70 and the AC lower arch gutter 71 are provided. Although the through-hole is shown, as shown in FIG. 9, a connection rubber 81 may be provided at the through-hole of the cover body to improve the appearance and stability of the ball exchange device. In the illustrated embodiment, a connection rubber 81 is provided at a portion where the AC upper gutter 70 and the AC lower arch gutter 71 of the tank cover 80 that covers the shape of the upper tank 6 and the AC tank 7 are penetrated. The gutter and the base of the AC lower arch gutter 71 are covered. With this configuration, the AC upper gutter 70 and the AC lower arch gutter 71 can be stably supported, and the beauty of the ball AC device can be improved. When the connection positions of the AC upper gutter 70 and the AC lower arch gutter 71 are slidable in order to change the connection positions, the connection rubber 81 may cover the slide grooves.

The ball AC device according to the present embodiment described above includes an AC upper gutter 70 gently inclined toward the center of the upper part between the adjacent AC tanks 7 and a lower part between the adjacent AC tanks 7. And an AC lower arch gutter 71 formed in an arch shape in which the upper center is connected and abutted at the lower center of the AC upper gutter 70, and the AC upper gutter 70 and the AC lower arch gutter 71 The pachinko balls flowing down the inside at the central intersection are guided in an intersecting manner, so that the AC upper gutter 70 formed in a straight line is formed by the arch structure of the AC lower arch gutter 71 formed in an arch shape. And the pachinko ball stays in the AC upper gutter 70 and the AC lower arch gutter 71, and can be twisted or bent by its weight. There. Therefore, unlike the conventional case, there is no need to support the AC gutter with a separately prepared supporting member, so that the structure is simple and the appearance is preferable. In the structure according to the present embodiment, when a ball is clogged at any point of the AC lower arch gutter 71 or on the downstream side and the ball flows backward through the AC lower arch gutter 71, the side from which the ball is sent out. Flows back through the AC lower arch gutter 71 through the AC lower arch gutter 71, so that the entire AC lower arch gutter 71 is not filled with balls, and the load can be reduced accordingly. Further, even if a thin material is used as a member constituting the AC upper gutter 70 and the AC lower arch gutter 71, sufficient strength for the arch structure can be obtained, and overall cost reduction can be achieved. it can.

Further, the AC lower arch gutter 71 guides the pachinko balls received in a cross shape from the AC upper gutter 70 provided in a gently inclined shape so as to reduce the speed of the pachinko balls in a substantially horizontal direction and gradually increase the speed. Therefore, it is possible to weaken the downward force of the pachinko balls flowing down as compared with a conventional inclined AC gutter that is guided linearly, and it is possible to suppress an accident that the AC tank on the receiving side is damaged.

Although the ball exchange device in the above-described embodiment has a configuration in which the upper tank 6 and the alternating current tank 7 are separately provided, these are formed in a single tank, and the inside is formed by the upper tank 6 and the upper tank 6 of the present embodiment. By partitioning to have a structure similar to that of the AC tank 7, one unit can be provided.

Next, the operation of the above ball exchange device will be described with reference to FIGS. FIG. 10 is a side view showing the internal structure of the pachinko island stand 1 showing the positions of the sensors S1 to S5 for controlling the stopper device 61 and the ball return device 3 of the ball exchange device, and FIG. FIG. 12 is a main flow chart showing control of the AC device, FIG. 12 is a flow chart showing a supply device control processing subroutine in the main flow chart, and FIG. 13 is a flow chart showing a receiving apparatus control processing subroutine in the main flow chart. FIG. 14 is a flowchart showing an additional processing subroutine in the main flowchart. FIGS. 15 to 17 are explanatory diagrams for explaining states corresponding to the respective flowcharts. FIG. It is a flowchart which shows operation | movement of the ball return apparatus 3.

In FIG. 10, in the present embodiment, four sensors are provided in the priority storage tank 11, and the sensor S1 on the most upstream side constitutes the lower limit sensor S1, and the sensor S2 on the downstream side of the sensor S1 is the lower limit sensor S1. The release sensor S2 is constituted, and the other two sensors are merely sensors for detecting the ball amount. On the other hand, the non-priority storage tank 12 is also provided with four sensors, the most downstream sensor S5 constituting the upper limit sensor S5, and the downstream sensor S4 of the sensor S5 constituting the upper limit release sensor S4. Further, one more sensor is placed, and the sensor S3 on the most upstream side constitutes the intermediate sensor S3. Among the above sensors S1 to S5, the lower limit sensor S1 and the upper limit sensor S5 are used for controlling the opening / closing operation of the ball returning device 3, and the lower limit release sensor S2 and the upper limit release sensor S4 are used for controlling the ball exchange device. The intermediate sensor S3 is not used in the present embodiment, and is simply used to control the amount of balls stored in the storage tanks 11 and 12, as in the case of the sensor without reference numeral. It is just a sensor.

Thus, among the operations controlled by the sensors S1 to S5, the ball exchange device control determines whether or not the upper limit release sensor S4 of the own island is ON in step 10 in FIG. It is determined whether or not the fuel is stored in the non-priority storage tank 12 at or above the upper limit release sensor S4. If it is determined that the fuel is stored, the supply flag is turned on in step S11. Thereafter, at step 12, a replenishing device control processing subroutine is executed.

As shown in FIG. 12, the replenishing device control process is performed while judging whether or not the adjacent left and right pachinko islands have reached the upper limit (position of the upper limit release sensor S4). That is, in step 40, it is determined whether or not the replenishment flag of both adjacent islands is ON (whether or not both adjacent islands have reached the upper limit). If both of the adjacent islands have also reached the upper limit, it is necessary to replenish. Since there is not, the supply flag of the own island is turned off in step 41, and the process proceeds to step 19 described later to close both shutters of the own island. On the other hand, when it is determined in step 40 that the replenishment flags of both neighboring islands are not ON, it is determined in step 42 whether the replenishment flag is ON in the left island. Therefore, in step 43, the stopper device 61 for supplying the ball to the left island (shutter and display; the same applies hereinafter) is closed, and if the left island replenishment flag is not ON, the left island is determined in step 44. Open the shutter to supply the ball. Similarly, in step 45, it is determined whether or not the replenishment flag is ON in the right island. If it is ON, it means that the right island has also reached the upper limit. If the supply flag for the right island is not ON, the shutter for supplying the ball to the right island is opened in step 47.

Thus, while the replenishing device control processing in step 12 is being executed, it is determined in step 13 whether or not the upper limit release sensor S4 has been turned off. If not, the process returns to step 11 and returns to step 11 When it is determined that the upper limit release sensor S4 has been turned OFF, the timer is reset in step 14, and then a timer for a fixed time (3 minutes in this embodiment) is set in step 15 and the timer is reset. Until the time (3 minutes) set by the timer elapses, the same supply device control processing as in step 12 is executed in step 16, and after it is determined in step 17 that 3 minutes have elapsed, the supply flag is turned off in step 18. In step 19, both shutters in the own island are closed, and the processing when the storage amount reaches the upper limit is ended.

By the operation realized by the processing of steps 10 to 19 described above, the shutter is opened and driven from when the detection output from the upper limit release sensor S4 is no longer derived until a predetermined time elapses. Since the storage amount at the end of the shutter opening operation can be reliably located upstream (small storage amount side) of the upper limit release sensor S4, there is some time margin before the upper limit release sensor S4 operates again. Therefore, for example, the return preventing time of the ball return device 3 can be minimized, and the prize ball can be smoothly returned by the player, so that the service can be improved. If the set time of the timer for measuring the fixed time can be changed and adjusted, the remaining storage amount on the upstream side from the upper limit release sensor S4 can be set to a desired storage amount.

The above-described replenishing device control process will be described with reference to FIG. 15 illustrating actual storage amounts of a plurality of pachinko islands 1 (in the case of five rows A to E), as shown in FIG. At the beginning of the business, the storage amounts of the pachinko islands A to E are substantially equal and slightly smaller than the sensor S4 are stored in the respective pachinko islands A to E as initial values. As shown in FIG. 15B, while the business continues, the storage amount varies, and, for example, if the storage amount of the central pachinko island C exceeds S4, the pachinko island C The shutter is opened to supply the balls to the pachinko islands B and D on both sides, and finally, as shown in FIG. 15C, the storage amount of the pachinko islands C is slightly smaller than the sensor S4 ( The left and right pachinko islands B and D are supplied so as to satisfy the above-described reduction by the timer). Further, as shown in FIG. 15 (D), when the storage amount of the pachinko islands B and C exceeds S4, no ball exchange is performed between the pachinko islands B and C. The movement of the ball from the island B to the pachinko island A and the movement of the ball from the pachinko island C to the pachinko island D are performed. Note that the phenomenon in which the stored amount of balls reaches the upper limit (exceeding the position of the sensor S4) as described above rarely occurs because the number of balls held by the player is large. The replenishing device control processing described above is performed in consideration of the case where the number of replenishments has increased.

On the other hand, the processing when the storage amount in the priority storage tank 11 has reached the lower limit, that is, it is determined in step 10 that the upper limit release sensor S4 is not ON, and in step 20, the lower limit release sensor S2 is OFF. When it is determined that the receiving flag is turned on in step 21, the receiving device control processing subroutine is executed in step 22, and the additional processing subroutine is executed in step 23.

う ち Of these, as shown in FIG. 13, the receiving device control processing in step 22 is performed while determining whether or not the adjacent left and right pachinko islands have reached the lower limit (position of the lower limit release sensor S2). That is, in step 50, it is determined whether or not the receiving flag of both neighboring islands is ON (whether or not both neighboring islands have also reached the lower limit). If both neighboring islands have also reached the lower limit, it is not received. Since there is no answer, the receiving flag of the own island is turned off in step 51, and the process proceeds to step 31 described later to close both shutters of the adjacent AC tanks 7 facing the own island. On the other hand, if it is determined in step 50 that the receiving flags of both neighboring islands are not ON, it is determined in step 52 whether the receiving flag is ON in the left island. In step 53, the shutter of the left island facing the own island (shutter and display; the same applies hereinafter) is closed to stop the ball reception, and the reception flag of the left island is not turned on in step 53. In step 54, the shutter of the left island facing the own island is opened to receive the ball. Similarly, in step 55, it is determined whether or not the receiving flag is ON in the right island. If it is ON, it means that the right island has also reached the lower limit. The shutter of the island is closed to stop receiving the ball. If the receiving flag of the right island is not ON, the shutter of the right island facing the own island is opened in step 57 to receive the ball and the subroutine is ended.

In addition, as shown in FIG. 14, the additional processing in step 23 specifies the next neighboring island on both sides of the island that has issued the receiving flag in step 60, and turns off the receiving flag of the island specified in step 61 (to the lower limit). It is determined whether or not the specified island has not reached the lower limit. If it is determined that the specified island has not reached the lower limit, the shutter of the specified island on the side of the island that has issued the reception flag is opened in step 62, and the specified island is opened. Is determined to have reached the lower limit, the shutter of the island specified in step 63 is closed, and the subroutine ends.

Thus, while the replenishing device control processing and the addition processing in steps 22 and 23 are being executed, it is determined in step 24 whether or not the lower limit release sensor S2 has been turned ON. When the lower limit release sensor S2 is determined to be ON, the shutter of the island specified in the additional processing is closed in step 25, and the timer is reset in step 26. In step 27, a timer for a fixed time (3 minutes in the present embodiment) is set, and the same receiving device control processing as in step 22 is executed in step 28 until the time (3 minutes) set by the timer elapses. After it is determined in step 29 that three minutes have elapsed, the receiving flag is turned off in step 30 and Accumulation volume by closing both shutters of the AC tank 7 on both sides facing the ends the processing when it reaches the lower limit.

By the operation realized by the processes of steps 20 to 31 described above, the pachinko machines on both sides are controlled in the receiving device control process from when the detection output from the lower limit release sensor S2 is no longer derived until a predetermined time elapses. Since the shutter of the island stand 1 is driven to open and the storage amount at the end of the opening operation of the shutter can be reliably located downstream (the side where the storage amount is large) of the lower limit release sensor S2, the lower limit release sensor is again activated. Since it is possible to have some time allowance before the operation of S2, for example, it is possible to minimize the return prevention time of the ball return device 3 of the pachinko island stand 1 on both sides, and to return the prize ball by the player. Can be performed smoothly, and the service can be improved. Further, if the set time of the timer for measuring the fixed time can be changed and adjusted, the remaining storage amount on the downstream side from the lower limit release sensor S2 can be set to a desired storage amount.

Further, in the additional processing, further adjacent pachinko islands are configured to receive replenishment of the balls from the outer pachinko islands via the ball interchange device, so that the ball storage amount of each pachinko islands is reduced. It is possible to reduce the increase / decrease width to make the storage amount uniform, to quickly respond to the reduction / increase of the storage amount, and as a result, to shorten the time during which the return to the entire ball return device 3 is prohibited. Can be.

The above-described receiving device control processing and additional processing will be described with reference to FIGS. 16 and 17 which illustrate actual storage amounts of a plurality of pachinko islands 1 (in the case of five rows A to E). First, in the receiving device control process, as shown in FIG. 16A, the storage amounts of the plurality of pachinko islands A to E often decrease and vary as compared with the initial values as the business continues. When, for example, the storage amount of the pachinko island C in the center becomes equal to or less than S2, the shutters of the adjacent pachinko islands B and D are opened and a ball is placed on the pachinko island C. And finally, as shown in FIG. 16 (B), the left and right pachinko islands B are set so that the storage amount of the pachinko islands C is slightly larger than the sensor S2 (the amount increased by the timer described above). , D. Further, as shown in FIG. 16 (C), when the storage amount is less than or equal to S2 at the pachinko islands C and D, the ball is not exchanged between the pachinko islands C and D, The ball is supplied to the pachinko island C from the pachinko island B, and the ball is supplied to the pachinko island D from the pachinko island E. Finally, as shown in FIG. Replenishment is performed from the left and right pachinko islands B and E so that the stored amount is slightly larger than the sensor S2. Further, as shown in FIG. 16 (E), in all of the pachinko islands A to E, if the ball storage amount is equal to or less than S2, the ball exchange between the pachinko islands is not performed.

In the above-described receiving device control process, the ball exchange is performed only between the adjacent pachinko islands. However, in the present embodiment, when the sensor S2 is turned off, not only the adjacent pachinko islands but also the outermost pachinko islands are provided. An additional process is also performed in which ball exchange between the pachinko island and an adjacent pachinko island is performed. As shown in FIG. 17A, for example, when the storage amount of the center pachinko island stand C becomes equal to or less than S2, the shutters of the adjacent pachinko island stands B and D are opened as shown in FIG. At the same time as the balls are supplied to the pachinko islands C, the shutters of the pachinko islands A and E on the outside are also opened, and the balls are supplied from the pachinko islands A and E to the pachinko islands B and D. Even when the storage amount of the adjacent pachinko islands B and D is small, the number of balls replenished from the pachinko islands B and D to the pachinko island C is almost the same as the number of balls replenished from the pachinko islands A and E. The tables B and D are replenished, and as a result, as shown in FIG. 17B, the balls of the outermost pachinko islands A and E are finally replenished to the center pachinko island stand C. , Reduce the amount of increase or decrease of the ball storage amount of each pachinko island A to E Can be equal reservoirs amount, it is possible to quickly respond to a decrease, an increase in the storage amount.

In addition, since the phenomenon that the storage amount of the ball becomes the lower limit (the sensor S2 or less) frequently occurs when the number of balls held by the player increases, the above-described receiving device control process and the additional process include: This is an important control in the ball exchange device.

By the way, by performing the above-described replenishing device control process, receiving device control process, and additional process, in many cases, the return operation to the ball returning device 3 of all pachinko islands is not prohibited. It is conceivable, however, that in the event that the value becomes equal to or more than the upper limit or equal to or less than the lower limit, it is necessary to perform control to allow or prohibit the returning operation of the ball returning device 3 on the own island or another island. The control is performed according to a flowchart shown in FIG. Therefore, the control of the counter (ball return device 3) in FIG. 18 will be described. First, in step 70, it is determined whether or not the upper limit sensor S5 has been turned on (whether or not the upper limit has been reached). If it is determined, the counter of the own island is closed in step 71, the timer is reset in step 72, and then the timer is started in step 73, and in step 74, a predetermined time (for example, 10 minutes) by the timer is used. Is determined, the counter is opened in step 75 when a predetermined time has elapsed. On the other hand, if it is determined in step 70 that the upper limit sensor S5 is not ON, then it is determined in step 76 whether the lower limit sensor S1 has been turned OFF (whether the lower limit has been reached) or not. When it is determined that the time has been reached, the counter of the facing island is closed in step 77, the timer is reset in step 78, the timer is started in step 79, and the timer is started in step 80, and a predetermined time (for example, (10 minutes) has elapsed, and when the predetermined time has elapsed, the counter of the facing island is opened in step 81. Note that when it is determined “NO” in both Step 70 and Step 76, the counter control is not performed.

As described above, the control described above (the control according to the first embodiment) moves the ball to the adjacent pachinko island when the upper limit is reached, and receives the ball from the adjacent pachinko island when the lower limit is reached. Although the control for driving the ball exchange device of the pachinko island stand on the outer side of the pachinko island stand has been described, it is also possible to perform the control while monitoring the ball storage amounts of a plurality of pachinko island stands in a wider range. Such control (control according to the second embodiment) will be described with reference to FIGS. FIG. 19 is a side view showing the internal structure of the pachinko island stand 1 used for control according to the present embodiment, FIG. 20 is a main flow diagram showing control of the ball exchange device, and FIG.

FIG. 34 is a flowchart showing a normal lower limit process subroutine in the main flowchart. FIG. 35 is a flowchart showing the operation of the ball returning device 3.

In the pachinko island stand 1 in the control according to the second embodiment, as shown in FIG. 19, as compared with the pachinko island stand 1 (FIG. 10) in the control according to the first embodiment, as shown in FIG. The sensor S6 is provided (therefore, the sensor S5 corresponds to the upper limit canceling sensor S5). The sensor S6 controls the opening / closing operation of the ball return device 3 on the own island, and the sensors S1 to S5 control the ball exchange between the own island and other islands. The stopper device 61 of the device is controlled, and the lower limit sensor S1 controls the opening / closing operation of the ball returning device 3 on another island. Note that, also in the pachinko island stand 1 according to the second embodiment, the reference ball storage amount at the start of business is set at a position slightly downstream from the sensor S4.

Among the operations controlled by the sensors S1 to S6, the ball AC device control determines in FIG. 20 whether or not there is an island for which the upper limit release sensor S5 has been turned on in step 90. When it is determined that there is, the upper limit priority control processing subroutine is executed in step 91. This upper limit priority control processing subroutine is shown in FIG.

In FIG. 21, the island for which the sensor S5 is determined to be turned on in step 90 is confirmed to be a signal from, for example, the island B in step 110. Thereafter, in step 111, the ball quantity data of all the islands is determined by the sensors S1 to S1. Extraction is performed based on the presence or absence of the detection in S6, and the least island is searched from the extracted data in step 112 to select one island. Thereafter, the island selected as the least island in step 113 is confirmed to be, for example, E island, and it is determined in step 114 whether the customer-attached flag of the confirmed E island is ON. As shown in FIG. 23, the customer-attached flag is set in advance to be ON or OFF at a ratio of the number of customers playing on the E island. It is set so that it is turned on when it is 10% or less, and turned off when it is larger than 10%. In addition, the calculation of the attending rate is based on the total number of the pachinko machines 2 installed on the pachinko island stand as the denominator, and on the other hand, the pachinko machines actually playing the game (detectable by the ON signal of the operation handle). It is calculated by taking numbers as numerators. If the visitor flag on the island E is not ON at step 114 (that is, if the visitor on the island E exceeds 10%), the following steps 115 and 116 are executed. And the upper limit priority control processing subroutine ends. On the other hand, when it is determined in step 114 that the guest-attached flag is ON (that is, the guest-emission is 10% or less on the island E), in step 115, the most balls from the island B which has issued the ON signal from the sensor S5. The control of the islands other than the island E specified as the island with the small storage amount is controlled by a subroutine that executes processing equivalent to steps 92 to 100 of the main routine. Processing is executed. Note that the reason why the upper limit priority processing is not executed when the number of guests is high is that the amount of balls returned afterwards is expected to increase when the number of guests is high. This is to prevent unnecessary movement of the ball by not moving the ball.

As shown in FIG. 22, in the upper limit priority process of step 116, first, both shutters of each island from island B to island E are closed in step 120, and then, in step 121, E of each island from island B to island E is closed. Open only the island side shutter. As a result, the ball on the island B is moved to the island C, the ball on the island C is moved to the island D, and the ball on the island D is moved to the island E. However, the number of balls moved per unit time is almost the same. (3,000 pieces / minute), it is the same as the ball moving from the island B to the island E after all. The opening of the shutter described above is continued until it is determined that the sensor S4 of the island B is turned off or the sensor S4 of the island E is turned on in step 122. When such a determination is made, In step 123, both shutters on each of the islands B to E are closed, and the upper-limit priority processing and the upper-limit priority control processing are terminated.

The upper limit priority control process described above will be described with reference to FIG. 25 illustrating actual storage amounts of a plurality of pachinko islands 1 (in the case of five rows A to E), as shown in FIG. The shutter on the E island side from the island B determined to have reached the upper limit after the sensor S5 has been turned ON to the island E determined to have the least amount of storage is opened, and the ball of the island B is opened as shown by the arrow. Is moved to island C, the ball on island C is moved to island D, and the ball on island D is moved to island E. When the sensor S4 of the island B is turned off, the shutter that has been opened closes to stop the movement of the ball. At that time, the storage amount of the ball on each island from the island B to the island E is as shown in FIG. As shown in (1), it is natural that the number of islands B is reduced and the number of islands E is increased, but there is no change in the storage amount of the intermediate islands C and D. That is, the ball has moved from the island B to the island E. As described above, in the upper limit priority control process, since the ball storage amount can be moved from the pachinko island 1 (B) in which the ball storage amount has reached the upper limit to the pachinko island 1 (E) having the smallest ball amount, the storage amount is reduced. -It is possible to quickly respond to the increase, and as a result, it is possible to shorten the time during which the return to the entire ball returning device 3 is prohibited.

In the above-described control, the condition for executing the upper limit priority process in step 116 is determined by ON / OFF of the guest-attached flag. The upper-limit priority process may be executed for a predetermined time. Specifically, as shown in FIG. 24, assuming that a maximum of 30,000 pieces are supplied, if the attending rate is 10% or less, the maximum number (30,000 pieces) is sent, and the attending rate is further increased. If it is 49% or less, 60% of the maximum number is sent. If the attending rate is 50% or more and 79% or less, 30% of the maximum number is sent. If the attending rate is 80% or more, , Set not to send at all. In the case of the ball feed amount as described above, the number of balls sent by opening one stopper device 61 (shutter) is 3000 pieces / minute, so the opening time according to each customer attending rate is 10 minutes. , 6 minutes, 3 minutes, and 0 minutes.

When the E island is confirmed in step 113 of FIG. 21, instead of step 114, the shutter opening time based on the table of FIG. 24 is calculated in step 117, and then steps 115 and 116 are executed. In the upper limit priority process, the upper limit priority process is executed by replacing the step 122 with the determination process of step 124 in which the opening time of the island B has elapsed or the sensor S4 of the island E has been turned on. Things. In this way, the amount of movement of the ball from the pachinko island B which has reached the upper limit to the pachinko island E specified as having the least amount of balls is controlled by the time according to the arrival to the specified pachinko island E. This makes it possible to precisely control according to the predicted value of the ball to be returned to the specified pachinko island E, thereby preventing useless exchange of the ball.

Returning to FIG. 20, when it is determined in step 90 that there is no island in which the sensor S5 is turned on, it is determined in step 92 whether there is an island in which the sensor S4 is turned on (a storage amount larger than the reference storage amount). If there is an island for which the sensor S4 has been turned ON, the normal upper limit process of step 93 is executed. This normal upper limit processing is shown in FIG. That is, the replenishment flag of the island for which the sensor S4 has been turned on is turned on in step 130, and then the replenishment device control processing subroutine is executed in step 131. The replenishing device control processing is exactly the same as the processing procedure shown in FIG. 12 described above, and thus the description thereof is omitted here. Thus, it is determined whether or not the sensor S4 has been turned off in step 132 while the replenishing device control processing in step 131 is being executed. If not, the process returns to step 130 and returns to steps 130 to 132. Is repeated, and when it is determined that the sensor S4 is turned off, the timer is reset in step 133, and then a timer for a fixed time (3 minutes in the present embodiment) is set in step 134, and the timer is set by the timer. Until the elapsed time (3 minutes) has elapsed, the same supply device control processing as in step 131 is executed in step 135, and after it is determined in step 136 that 3 minutes have elapsed, the supply flag is turned off in step 137, and At 138, both shutters in the island are closed to terminate the processing when the storage amount reaches the upper limit. .

By the operation realized by the processing of steps 130 to 138 described above, the shutter is opened and driven from when the detection output from the sensor S4 is no longer derived until a predetermined time elapses. Since the storage amount at the end of the opening operation can be reliably located upstream (small storage amount side) of the sensor S4, it is possible to have some time allowance before the operation of the sensor S4 again. For example, the return blocking time of the ball return device 3 can be minimized, and the prize ball can be smoothly returned by the player, so that the service can be improved.

Returning to FIG. 20, when it is determined in step 92 that there is no island whose sensor S4 is turned on, it is determined in step 94 whether there is any island whose sensor S3 is turned on. Since the sensor S3 detects an amount slightly larger than the median value of the amount of stored balls in the pachinko island stand 1, there is no problem in continuing normal business, so it is determined that there is an island where the sensor S3 is ON. If so, it is determined in step 95 whether or not the sending data is stored in the island. If the sending data is stored, the ball return process is executed in step 96. Although the ball return processing and the feed data will be described later in detail, when the island where the sensor S3 is turned on has received a ball in the past by the lower limit priority control processing, the same ball quantity as the received ball is returned. It is. Therefore, the ball return process will be described in detail after the lower limit priority control process is described.

Returning to FIG. 20, when it is determined in step 94 that there is no island in which the sensor S3 is turned on, it is determined in step 97 whether there is an island in which the sensor S1 (lower limit sensor) is turned off (island below the lower limit). If it is determined that there is an island for which the sensor S1 has been turned off, a lower limit priority control process of step 98 is executed. This lower limit priority control processing subroutine is as shown in FIG.

In FIG. 27, the island for which it is determined that the sensor S1 has been turned off in the step 97 is confirmed in step 140 to be a signal from, for example, the island A, and thereafter, in step 141, the ball amount data of all the islands is detected by the sensors S1 to S1. It is extracted in accordance with the presence or absence of the detection of S6, and it is determined in step 142 whether or not there is an island other than the island A and the sensor S2 is ON from the extracted data, and there is no island where the sensor S2 is ON. Is determined (the amount of accumulated balls on other islands is also small), the lower-limit priority control processing subroutine ends without executing the following processing. On the other hand, when it is determined that there is an island for which the sensor S2 has been turned on, it is determined in step 143 whether or not only one island has been turned on for the sensor S2. One island closest to island A is selected, and one is confirmed in step 145. For example, if it is confirmed that the island is the island C, the control of the islands other than the island C which is specified as the closest island with the storage amount equal to or more than the sensor S2 from the island A which issued the OFF signal from the sensor S1 in step 146 is performed. Is controlled by a subroutine that executes processing equivalent to steps 92 to 100 of the main routine, and the lower limit priority processing of step 147 is executed for islands A to C.

As shown in FIG. 28, the lower limit priority processing of step 147 first resets a timer for timekeeping in step 150, starts timekeeping in step 151, and thereafter, in step 152, performs a process from island A to island C. After closing both shutters of each island, in step 153, only the shutter on the A island side of each of the islands A to C is opened. As a result, the ball on the island C is moved to the island B, and the ball on the island B is moved to the island A. Since the number of balls moved per unit time is almost the same (3,000 pieces / min), In the end, it is the same as moving the ball from Island C to Island A. The opening of the shutter is continued until it is determined in step 154 that the sensor S2 of the island A is ON or the sensor S2 of the island C is OFF. When such determination is made, At step 155, both shutters of each island from island A to island C are closed. Then, at step 156, time measurement is terminated, and at step 157, the feed data calculation processing subroutine is executed to terminate the lower limit priority processing and the lower limit priority control processing. I do.

As shown in FIG. 29, the feed data calculation processing in step 157 stores the time T measured by the processing in steps 151 to 156 in step 160, and extracts the data of all islands in step 161. At 162, it is determined whether or not the lower limit priority processing from the island C to the island A is the first time. If it is the first time, the counter n is set to "1" at step 163; The value of “n + 1” is set to n, then the time stored in step 60 is set as time data of TCA (n) in step 165, and TCA (n) is stored as time data of island A in step 166. In step 167, the total value W (CA) of the stored TCA (n) is calculated. Thereafter, it is determined in step 168 whether or not lower limit priority processing has been performed on islands A to C, and if so, in step 169, the magnitudes of W (CA) and W (AC) are compared and steps 170 and 172 are compared. , A small value is subtracted from a large value, and a numerical value that becomes a positive value is stored in steps 171 and 173 in the total data W (CA) or W (AC). The feed data calculated in this manner is used in the ball return process (step 96) described later in detail.

The lower limit priority control process described above will be described with reference to FIG. 30 illustrating actual storage amounts of a plurality of pachinko islands 1 (in the case of five rows A to E), as shown in FIG. The shutter on the A island side from the island A determined to have reached the lower limit after the sensor S1 has been turned OFF to the island C determined to have a storage amount equal to or greater than the sensor S2 is opened, and as shown by the arrow, the shutter on the island A is opened. The ball of the island is moved to the island B, and the ball of the island B is moved to the island A. Then, when the sensor S2 of the island C is turned off, the shutter that has been opened closes to stop the movement of the ball. At that time, the storage amount of the ball on each island from the island A to the island C is as shown in FIG. As shown in (1), it is natural that the number of islands C decreases and the number of islands A increases, but the storage amount of the intermediate island B does not change. That is, the ball has moved from the island C to the island A. As described above, in the lower limit priority control process, the ball can be moved from the pachinko island stand 1 (C) having the storage amount equal to or more than the predetermined amount to the pachinko island stand 1 (A) having the ball storage amount reaching the lower limit. Therefore, it is possible to promptly respond to a decrease or increase in the storage amount, and as a result, it is possible to shorten the time during which the return of the entire ball return device 3 is prohibited.

Here, the ball return process in step 96 will be described with reference to FIGS. 31 to 33. The feed data of the island for which the sensor S3 is turned on in step 180 in FIG. (For example, even when the data is viewed mainly from the island A, there are a plurality of data to be sent to the island C, data to be sent to the island D, and the like). The island on the sending side is confirmed from the sending data, the receiving side is determined as C island in step 183, and the sending side is determined as A island in step 184. Then, after closing both shutters of each island from C island to A island in step 185 shown in FIG. 32, the shutter on the A island side of each island from C island to A island is opened in step 186, and the opening operation is performed. And continues until it is determined in step 187 that the data time W (CA) has elapsed. If it is determined that the feed data time has elapsed, both shutters from the island C to the island A are all closed at step 188, and then at step 189, the data W (CA) and all the TCAs are erased and the ball is erased. The return processing subroutine ends.

The above-mentioned ball return processing will be described with reference to FIG. 33 illustrating actual storage amounts of a plurality of pachinko islands 1 (in the case of five rows A to E). As shown in FIG. When the sensor S3 is turned on, the shutter on the island A from the island A determined to be the sending side to the island C determined to be the receiving side is opened, and the ball of the island A is moved to the island B as indicated by the arrow. , The ball of Island B is moved to Island C. Then, when the feed data time elapses, the shutter that has been opened closes and stops the movement of the balls. At that time, the storage amount of the balls on each of the islands A to C is as shown in FIG. In addition, it is natural that the number of the islands A decreases and the number of the islands C increases, but the storage amount of the intermediate island B does not change. That is, the ball has moved from the island A to the island C. As described above, in the ball return processing, the pachinko island stand A, which has reached the lower limit at first, recovers its ball storage amount by the moved AC ball which is not enough with its own stored ball alone, but the final ball is returned by the customer's returned ball. There is a possibility of storing more than the initial ball storage amount, and when the storage amount returns to the predetermined value, by returning the number of balls replenished during business hours to the replenished pachinko island stand C, all The amount of storage in Pachinko Island can be quickly equalized with the initial value.

Returning to FIG. 20, when it is determined in step 97 that there is no island with S1 turned off, it is determined in step 99 whether there is an island with S2 turned off (whether or not there is an island approaching the lower limit). You. If there is an island for which the sensor S2 has been turned off, the normal lower limit processing of step 100 is executed. This normal lower limit processing is shown in FIG. That is, in step 190, the receiving flag of the island for which the sensor S2 has been turned off is turned on, and then in step 191 the receiving device control processing subroutine is executed. This receiving device control processing is exactly the same as the processing procedure shown in FIG. 13 described above, and a description thereof will be omitted here. Thus, it is determined in step 192 whether or not the sensor S2 has been turned on while the receiving device control processing in step 191 is being executed. If not, the process returns to step 190 and returns to steps 190 to 192. When it is determined that the sensor S2 is turned on, the timer is reset in step 193, and then in step 194, a timer for a fixed time (3 minutes in the present embodiment) is set, and the timer is set. Until the elapsed time (3 minutes) elapses, the same receiving device control processing as in step 191 is executed in step 195, and after it is determined in step 196 that 3 minutes have elapsed, the receiving flag is turned off in step 197, and At 198, the shutters (stopper device 61) on both neighboring islands facing the own island are closed to reduce the storage amount. To end process at the time of close to.

By the operation realized by the above-described steps 190 to 198, the shutter is driven to open until a predetermined period of time elapses from the time when the detection output from the sensor S2 is no longer derived. Since the storage amount at the end of the opening operation can be reliably located downstream (larger storage amount side) than the sensor S2, it is possible to have some time margin before the operation of the sensor S2 again. For example, the return prevention time of the facing ball return device 3 can be minimized, and the prize ball can be smoothly returned by the player, so that the service can be improved.

By performing the above-described upper limit priority control process, normal upper limit process, ball return process, lower limit priority control process, and normal lower limit process, in many cases, the return operation to the ball return devices 3 of all pachinko islands is performed. It is considered that it will not be prohibited, but in the event that it becomes above the upper limit or below the lower limit, control must be performed to allow or prohibit the return operation of the ball return device 3 on the own island or another island. However, such control is performed according to the flowchart shown in FIG. Therefore, the control of the counter (ball return device 3) in FIG. 35 will be described. First, in step 200, it is determined whether or not the upper limit sensor S6 has been turned ON (whether or not the upper limit has been reached). If it is determined, the counter of the island is closed in step 201, the timer is reset in step 202, and then the timer is started in step 203. In step 204, a predetermined time (for example, 10 minutes) by the timer is used. Is determined, the counter is opened in step 205 when a predetermined time has elapsed. On the other hand, if it is determined in step 200 that the upper limit sensor S6 is not ON, then it is determined in step 206 whether the lower limit sensor S1 has been turned OFF (whether or not the lower limit has been reached). When it is determined that the timer has reached, the counter of the facing island is closed in step 207, the timer is reset in step 208, and then the timer is started in step 209. (10 minutes) has elapsed, and when the predetermined time has elapsed, the counter of the facing island is opened in step 211. Note that when it is determined “NO” in both Step 200 and Step 206, the counter control is not performed.

As described above, two control methods have been described for the control of the ball AC device passed between the pachinko islands 1. In the above control, the pachinko islands A to E have been exemplified and shown. In a game hall, it is normal to have more pachinko islands than the above, and in such a case, even if all pachinko islands are configured to have an AC relationship and the above-described control is performed.
