Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a plurality of pachinko machines arranged side by side and arranged in the lower space thereof to store the pachinko balls used on the pachinko island stand, and to store the pachinko balls from the outlet on the downstream side thereof. The present invention relates to a pachinko island stand having a built-in storage tank that supplies a pachinko ball stored toward a ball pumping device that pumps a ball to the upper part.

[0002]

2. Description of the Related Art In recent years, prize balls obtained by a player are directly returned to a pachinko island through a ball return device, and prize balls returned to a prize exchange area as before are returned to each pachinko island. A mechanism for omitting a mechanism has been proposed. Such a pachinko island has a large storage tank for storing returned pachinko balls.

As a pachinko island stand equipped with such a storage tank, the applicant has previously filed a public application as Japanese Patent Application No. 63-37760 (Japanese Patent Publication No. 6-44947;
Hereinafter, referred to as the first prior art), and Japanese Patent Application No. 5-2356
No. 19 (Japanese Patent Application Laid-Open No. 7-59937; hereinafter referred to as second prior art) was proposed.

In the first prior art, a pair of partition walls are erected in the center of the inside of the storage tank, and an out ball guide path (referred to as a guide rail portion) is provided in which the out balls flow down in the upper stage of the partition walls. , A bypass guideway that guides the pachinko balls stored in the storage tank to the downstream (referred to as the guide slope)
The ball storage portion of the storage tank and the bypass guide path are communicated with each other through a plurality of storage sphere inlets that are formed at a predetermined interval from upstream to downstream. On the other hand, in the second prior art, a pair of storage tanks are provided on both the left and right sides of the ball hoisting device on the pachinko island stand, and one of the storage tanks is set as a priority storage tank in which balls are preferentially stored.・ The above-mentioned bypass taxiway and out-ball taxiway were not provided inside both non-priority storage tanks, and the priority tank side was faced with a ball returning device for returning prize balls.

[0005]

In the storage tank of the first prior art, however, a pair of partition walls are erected at the center of the tank so that balls are not stored in the partition walls. Since the volume of the storage portion for storing balls is small, there is a drawback that the storage tank becomes large if an attempt is made to store a predetermined amount of pachinko balls. In order to eliminate such a drawback, the storage of the second prior art It may be possible not to provide a bypass taxiway or an out ball taxiway like a tank, but if it is configured without a bypass taxiway or an out ball taxiway, a part of the pachinko balls stored in the storage tank The ball has a drawback that it stays in one place for a long time and gets rusted.

Therefore, in order to solve the drawbacks of both prior arts, it is conceivable to combine both prior arts to lower the height of the partition wall and cover the upper surface of the upper out ball guide path. Since the configuration of the lower bypass taxiway is formed as one taxiway for multiple storage ball entrances, the pachinko balls that flow into the bypass taxiway from the downstream storage ball entrance flow down preferentially. As a result, the pachinko balls that have flowed into the bypass taxiway from the upstream storage ball inlet do not easily flow down, and as a result, the storage pachinko balls on the upstream side of the storage tank stay and rust for a long period of time. Is still conceivable. The present invention has been made in view of the above circumstances, and its main purpose is to store a large amount of pachinko balls and the stored pachinko balls do not stay for a long period of time. To provide a pachinko island stand with a tank.

When the ball returning device is faced to the priority storage tank side as in the second prior art, the priority storage tank is often full in a normal business state. When prize balls are returned from the ball returning device to the priority storage tank that is full, the returned pachinko balls are not returned by the full pachinko balls, so they are not taken in from the ball returning device. was there. The present invention has been made in view of the above circumstances, and its object is to store a large amount of pachinko balls and prevent the accumulated pachinko balls from staying for a long period of time. Another object of the present invention is to provide a pachinko island stand equipped with a storage tank capable of receiving balls returned from the ball returning device at any time.

[0008]

In order to achieve the above-mentioned object, in the present invention, as shown in FIGS. 3 to 5, the storage tanks 12 and 13 are provided at the bottom corners thereof. The upstream inlet 39a faces the upstream portion of the storage tanks 12 and 13, and the downstream outlet 39b has a length substantially the same as the longitudinal dimension of the storage tanks 1 and 12.

7 is provided in an inclined shape toward the end of the storage tank 13 while being supported by the overflow box 14
The pachinko balls flowing down from the non-priority passage 14b and most of the pachinko balls falling from the out-ball collecting box 10 are caused to flow toward the end of the storage tank 13, and part of them in the process of flowing down. A pair of pachinko balls overflowing gutter 2
6 is dropped into the storage space of the storage tank 13 from the interval of 6. In addition, in order to adjust the rate at which the pachinko balls rolling on the overflow ball gutter 26 fall on the way without reaching the rear end, the adjustment screw 29 can be used. Further, the upper plate 23 is provided with a branching projection plate 24 at the center on the downstream side thereof for branching the pachinko balls dropped on the upper plate 23 into the overflow ball gutters 26 on the left and right, and at the upstream center thereof, a connection described later. The outflow port 25 for connecting the gutter 52 is formed. The outlet 25 is for guiding a part of the pachinko balls returned from the ball returning device 3 toward the other storage tank 12.

At the front end of the storage tank 13 and below the upper plate 23, a pressure relief plate 35 is provided in an inclined shape.
As shown in 0, when a large amount of pachinko balls are stored, the pachinko balls other than the pachinko balls flowing down the respective guide paths 39, 40, 41 described below are surely discharged to the outlet 37. It is provided for this purpose. Therefore,
The pressure relief plate 35 is fixed such that the distance between the tip of the pressure relief plate 35 and a cover body 42 described later is smaller than the diameter of the pachinko ball.

A guide plate 36 having a substantially triangular shape is fixed to the lower end (front end) of the bottom plate 21 of the tank base 20 to guide the pachinko balls flowing down the bottom plate 21 according to its inclination. A lead-out port 37 is formed at the guide destination of the guide plate 36. To the outlet 37, an introduction gutter that guides the pachinko balls flowing out from the outlet 37 to the doffing device 5 in a line is connected. Also,
A top priority connector 38, to which the lower end of the top priority hose 16 is connected, is fixed to the center of the portion of the storage tank 13 near the downstream side. The connection port 38 has an outlet port toward the downstream side. Since it is formed, the pachinko balls guided by the highest priority hose 16 flow down the bottom plate 21 toward the downstream side,
When the pachinko balls that flow down stay and reach the outlet portion of the connector 38, no further outflow occurs, and the pachinko balls are stored in the highest priority hose 16 and finally reach the upper end of the highest priority hose 16. Then, the pachinko balls overflowing into the overflow box 14 are guided to the priority passage 14a.

Further, inside the storage tank 12, as described above, the bypass guiding paths 39, 40 and the out ball guiding path 41 are provided in the lower corner portion of the inclined lower end side plate 22 side. That is, as shown in FIG. 5, FIG. 6 and FIG.
The corner portion formed by the bottom plate 21 and the inclined lower end side plate 22 of the storage tank 13 has substantially the same length as the longitudinal dimension of the storage tank 13 and its upstream inlet 39a faces the upstream portion of the storage tank 13. At the same time, the first bypass guide passage 39 having a U-shaped cross section, whose downstream outlet 39b faces the upstream side of the outlet 37 formed at the downstream end of the storage tank 13, is fixed to the bottom plate 21 by the screw 50. Adjacent to the bypass guiding path 39 of the storage tank 13 is approximately half the longitudinal dimension of the storage tank 13 and its upstream inlet 40a faces the midstream portion of the storage tank 13 and its downstream outlet 40b is slightly upstream of the outlet 37. The second bypass guideway 40 having a U-shaped cross section facing the side is fixed to the bottom plate 21 by the screw 50, and the upstream inlet 41a thereof is stored adjacent to the upper portion of the first bypass guideway 39. Downstream outlet communicates with the out ball guide rail 11 connected to the upstream end of the link 13 4

Then, these three taxiways 39, 40,
41 to cover the upper part and one side
Are attached to the side plate 22 by attachment fittings 51. In addition, the entrance 3 of the first bypass taxiway 39
9a and the inlet 40a of the second bypass guide passage 40 are formed by cutting out the side surface of the cover body 42.
Further, the inlet 41a of the out-ball guiding path 41 is previously formed in a three-dimensional cylindrical shape having a triangular shape, and is fixed to the side plate 22 of the tank base 20 and the rear wall with a screw and is connected to the rear wall of the storage tank 13. It is communicated with the out ball guide rail 11. Furthermore,
The outlets 39b and 40b of the bypass guide paths 39 and 40 are located slightly forward of the outlet 37 and face the position where the pachinko balls that are guided by the guide plate 36 can join by rolling the bottom plate 21. The outlet 41b of the out ball guideway 41 is located in front of the outlets and is located at the outlet 37.
Just before. In this way, the outlet 41b of the out ball guideway 41 is connected to the outlet 3 of the bypass guideways 39, 40.
By positioning 9b, 40b and the bottom plate 21 in front of and above the rolling ball outlet, the balls from the out ball guiding path 41 are preferentially guided to the outlet 37, and the out ball guiding path 41 and the out Used pachinko balls do not stay on the ball guide rail 11. In addition, in guiding the pachinko balls flowing out from the outlets 39b, 40b of the bypass guide paths 39, 40 and the outlets of the balls rolling on the bottom plate 21 to the outlet 37, there is no superiority or inferiority between them and they are guided evenly. Is.

In addition to the above-described structure, the storage tank 13 has each guide path 39, as shown in FIGS. 1, 2, and 12.
On the downstream side of the side plate 22 opposite to the installation side of 40 and 41, a beading hole 43 for beading out the inner balls when a trouble occurs such that the balls do not flow in the storage tank 13 and flows,
A rectangular inspection opening 46 for repairing and inspecting the guideways 39, 40, 41 is formed downstream of the side plate 22 on the installation side of the guideways 39, 40, 41.

First, the bleeding hole 43 will be described.
The beading hole 43 is a slide plate 4 that slides vertically.
4 is closed, and an opening / closing lid 45 is provided on the waist plate 34 at a position corresponding to the slide plate 44. Therefore, when troubles such as ball retention occur in the storage tank 13, the slide plate 4 is opened after the opening / closing lid 45 is opened.
By raising 4 the stored balls in the storage tank 13 can be taken out by opening the beading hole 43 and the opening / closing lid 45.

Next, the inspection opening 46 will be described.
The inspection opening 46 is normally closed by a closing plate 47, and the closing plate 47 is covered by the waist plate 34. Therefore, in order to remove the closing plate 47, the waist plate 3
4, the waist plate 34 of the inspection opening 46 (the inside of the part indicated by the reference numeral 34 in FIG. 1) has a lower part thereof as shown in FIG.
2 is locked by a latching metal 48 fixed to 2, and only an upper portion thereof is screwed by a screw 49.
After loosening and removing 9, the waist plate 34 can be easily removed by removing the engagement with the hook 48. When the blocking plate 47 is removed in such a state, a part of the side surface of the first bypass guide path 39 and the out-ball guide path 41 faces the inspection opening 46, so that the pachinko machine 2 is opened and a screw is applied from above. Repair and inspection can be performed by taking out the respective guide paths 39, 40, 41 in which 50 is loosened and moved so as to be taken out from the inspection opening 46. In addition, the reason why this repair and inspection can be performed from the inspection opening 46 is that the pachinko machine 2 is opened and looked into from above, and each of the guideways 39, 40, 41.
This is because the wiring can hardly be taken out by the wiring inside the island or the rear extension of the counter stand 33.

Although the pair of storage tanks 12 and 13 have been described above with respect to a substantially common structure, the non-priority storage tank 13 has the above-mentioned structure, as shown in FIGS. 9 and 10. The outflow port 25 is formed in the upper plate 23, whereas the outflow port 25 is not formed in the upper plate 23 of the priority storage tank 12. Instead, the priority storage tank 12 is provided with a return duct 53 below the upper plate 23, and the return duct 53 and the outlet 25 of the non-priority storage tank 13 are connected by a communication gutter 52. These configurations guide a part of the balls returned from the ball returning device 3 to the priority storage tank 12 side via the connection gutter 52.

As described above, the storage tanks 12 and 1 according to the embodiment

Since the pachinko balls staying in the downstream portions of 2 and 13 are directly guided to the outlet 37, the pachinko balls staying in any of the storage tanks 12 and 13 can be surely led out. It can be led to 37, and the accumulated balls do not stay for a long time. In the illustrated embodiment, the pachinko balls that have entered from the inlet 39a of the first bypass guiding path 39 are also guided to the second bypass guiding path 40, so that the pachinko balls in the upstream portion and the middle-stream portion are provided. Although the pachinko balls that enter from the entrance 39a may be guided only to the first bypass guide path 39, the pachinko balls may be guided.

Further, the storage tanks 12 and 13 having the above-described structure are provided on both sides of the doffing device 5 of the pachinko island stand 1, and the doffing device is provided in each of the storage tanks 12 and 13. The pachinko balls that are pumped out by the No. 5 are connected to an overflow mechanism 14 that preferentially circulates the overflowed pachinko balls to one of the storage tanks 12, and at least the non-priority side storage tank 13 is built in. From the ball returning device 3 to the non-priority side storage tank 13 which does not become almost full in the normal business state by facing the machine row side with the ball returning device 3 for returning the prize balls acquired by the player It is possible to reliably return the prize balls.

[0030]

As is apparent from the above description, in the present invention, firstly, a bypass guideway and an out ball guideway are provided at the corners of the storage tank, and the pachinko machine is also provided above them. Since it is configured to be able to store balls, it is possible to store a large amount of pachinko balls,
Secondly, the pachinko balls staying in the upstream part of the storage tank are in the first bypass taxiway, and the pachinko balls staying in the midstream part of the storage tank are in the second bypass taxiway, respectively. It is configured to guide the pachinko balls staying in the downstream part of the storage tank directly to the outlet, so that the pachinko balls staying in any part of the storage tank can be surely guided to the outlet. It is possible to prevent the accumulated balls from staying for a long time.

Storage tanks having the above-mentioned structure are provided on both sides of the ball-lifting device on the pachinko island stand, and each of the storage tanks is filled with the pachinko balls pumped by the ball-lifting device. There is an overflow mechanism that gives priority to recirculating the overflowed pachinko balls to one of the storage tanks, and at least the prize balls won by the player on the pachinko machine row side where the non-priority side storage tank is built. By facing the ball returning device to be returned, it is possible to surely return the prize balls from the ball returning device to the non-priority side storage tank, which is hardly filled in the normal business condition.
