DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a game machine in which a substantially horizontal top plate is supported on a waist plate extending parallel to each other, and a plurality of gaming machines are juxtaposed on the top plate so as to extend in two rows back to back. About Kijima. Here, the game machine mainly indicates a pachinko machine.

[0002]

2. Description of the Related Art In a conventional gaming machine island, pachinko balls discharged from two pachinko machines lined up in a back-to-back manner flow down by gravity into a collecting gutter obliquely provided in a lower part of the island and are received by a lower tank. The balls passed and stored in the lower tank were lifted and polished to the upper island side by a polishing and lifting device erected in the center of the island.

[0003] The recovery gutter in the lower island has a wide bottom surface and a large opening on the upper surface, and is polished so as to spread in the width direction of the island across the waist plates forming the front and rear surfaces of the lower island. It was skewed so as to extend one by one on both sides of the island below the feeder. In other words, the recovery gutter extends in the island width direction inside the lower island, and extends over the entire area inside the lower island while being inclined in the vertical direction.

[0004] An upper tank for storing pachinko balls is provided at the upper end of the polishing / lifting device in the upper island, and is inclined so as to extend left and right from the upper tank toward both island ends. Pachinko balls were distributed to each pachinko machine by using the distribution gutter and utilizing the inclination.

[0005]

However, in a conventional gaming machine island, the space occupied by the collection gutter in the lower island is large. In order to reduce the width of the island as much as it becomes obstructive or to reduce the width of the island as much as possible, it is difficult to set the width of the recovery gutter smaller than the width of the recovery gutter, even if you try to configure the lower part of the island that is the base of the entire island. There was a point.

By the way, according to the test conducted by the applicants, it has been empirically confirmed that even if the standardized width of the conventional collecting gutter is considerably reduced, it is possible to collect the ball discharged from the pachinko machine without any trouble. Have been. Conversely, in a conventional wide collection gutter, the ball tends to stay on the upstream side and remains as it is and rusts, or when the ball is discharged in a short period of time, the ball is placed on the bottom of the collection gutter. First, since the ball flows down after spreading, the flowability of the ball on the recovery gutter is deteriorated, and there is a possibility that the ball is not smoothly delivered to the polishing / lifting device side.

Further, even on the upper island, the supply gutter is disposed with a sufficient inclination so as to extend in the longitudinal direction of the island, so that not only does the supply gutter extend to a high position to take up space, but also the appearance is poor. Since the gutter extends for a considerably long time, it is necessary to constantly watch for clogging of the balls, and it is necessary to frequently perform maintenance, which is complicated and increases maintenance costs.
Further, in the case where fever is generated at the same time by several pachinko machines located at the downstream end of the supply / distribution gutter, there is a possibility that the supply of the pachinko balls cannot be made in time, which may cause inconvenience to the player.

The present invention has been made in view of the above-mentioned problems of the prior art, and the collection gutter can be compactly arranged without hindering the efficiency of collecting the game media in the lower island, and other related items can be provided. A game that can meet the demand for space saving without disturbing the installation of equipment, does not require a height at the top of the island, and can reliably and quickly supply game media to each gaming machine.

At this time, the balls collide with the alignment guide 44 having the curved surface facing the downstream side of the collection gutter 40, and are guided so as to roll in the upper and lower rows in the rotating conveyance direction of the lower polishing belt 51.

The spheres are uniformly rolled while being sandwiched between the upper and lower belts 51 and 55 as the lower polishing belt 51 is driven to rotate, and are reliably transported to the storage tank 30 while being polished. Since the upper polishing belt 55 of each upper polishing unit 54 can be resiliently displaced in the vertical direction together with the rollers 56 and 57, a large amount of balls may fall at one time, or the upper polishing belt 55 may be placed under any one of the upper polishing units 54. Even when the balls are concentrated, the upper polishing belt 55 can escape upward, and it is possible to prevent the balls from being clogged between the upper and lower belts 51 and 55.

Each of the upper polishing units 54 corresponds to each of the pachinko machines 11 located above,
Since the same number of pachinko machines 11 are provided, the upper polishing belt 55 in each upper polishing unit 54 can intensively polish the balls discharged from each pachinko machine 11 by one unit. Since each upper polishing unit 54 is detachable from the collection gutter 40, the assembling work is easy, and only the unit including the dirty upper polishing belt 55 can be easily replaced.

The balls collected by the collecting gutters 40 do not spread unnecessarily on the lower polishing belt 51 extending along the narrow bottom surface portion 41, but are more efficient than the wider collecting gutters. Is forcibly conveyed to the downstream side by the rotational drive of. The sphere polished and conveyed in each recovery gutter 40 in this manner is reliably transferred to the storage tank 30 through which the terminal port 43 passes.

The polished pachinko balls in the storage tank 30 are lifted by the lifting device 60 to the upper unit 10A.
It is temporarily stored in the upper tank 60a. In the upper unit 10A, the transport cart 110 is guided by the loop-shaped guide rail 100, the wheels 112 roll on the rail 100, and the transport cart 110 circulates. When there is no pachinko ball in the box-shaped main body 111, the ball shortage detection sensor 114 detects it, and based on that, the wheels 112 are driven to rotate.
Moves to a position to receive the pachinko balls ejected from and receives the pachinko balls.

When the pachinko machine 11 or the ball lending machine 11A which requires ball replenishment occurs, the wheels 112 are driven to rotate, and the transport cart 110 is set so that the ball discharge port 111a of the pachinko machine 11 is placed on the upper plate (not shown). It moves to a position facing the ball tank (not shown) of the ball lending machine 11A, the star wheels 113, 113 are driven to rotate, and a predetermined number of pachinko balls are counted through the ball passage member 115 to the pachinko ball. Machine 11 or ball rental machine 11A.

An openable / closable opening 143 for allowing the abrasive to enter and exit the cylindrical path 141 is also formed at the end of the cylindrical path 141. The end of the collection gutter 140 penetrates through the side end wall 32 of the storage tank 30 disposed in the center of the island and is connected to the tank 30. The end of the cylindrical path 141 having the separation hole 142 is connected to the tank 30. It extends to near the center.

Next, the operation will be described. The sphere that has fallen into the collection gutter 140 does not spread unnecessarily near the narrowly extending bottom, but is more efficiently collected than the collection gutter 14 having a wider width.
Flows down by its own weight in the direction where 0 is inclined. A polishing machine 150 is provided at the end side of each recovery gutter 140, and the pachinko balls reaching the cylindrical path 141 of the polishing machine 150 are stirred by the rotation of the screw member 151 so as to be evenly mixed with the granular abrasive. Is polished so that surface dirt is removed.

As shown in FIG. 8, while the pachinko ball is polished, it flows down by its own weight in the end direction of the cylindrical path 141 opposite to the conveying direction generated by the rotation of the screw member 151, and the end of the cylindrical path 141 Plurality of separation holes 142
From the collection gutter 140 to the outside. As described above, the sphere that has flowed down to the terminal end of the cylindrical path 141 by its own weight against the conveying force of the screw member 151 while being polished by the polishing machine 150 of the collection gutter 140 is in the storage tank 30 in which the terminal end is inserted. Will be handed over.

On the other hand, the abrasive having a larger diameter than the pachinko ball cannot pass through the separation hole 142 and remains in the polishing machine 150. However, since the abrasive has a lower specific gravity than the pachinko ball, the rotation of the screw member 151 causes the cylindrical member to rotate. After being sent in the direction of the starting end of 141, the cylindrical path 141 along with the spheres flowing down again
The reciprocating movement flowing down to the end direction of is repeated.

Accordingly, the abrasive material is not unevenly distributed on the end side of the cylindrical path 141, and is rubbed moderately with the ball over the entire inside of the cylindrical path 141 for polishing. An opening 143 is provided at the end side of the cylindrical path 141, so that by opening and closing the opening 143, the abrasive which has become very dirty can be easily taken out of the cylindrical path 141 or a clean abrasive can be removed from the cylindrical path 141. It can be introduced into the road 141.

The specific configuration of the gaming machine island according to the present invention is not limited to the illustrated embodiment. For example, the guide rail of the transport cart may be of a monorail type, or may itself be driven for movement of the cart. Further, a polishing / lifting device may be provided upright in the storage tank to polish the game medium to the upper level of the island without providing a polishing machine in the pair of recovery gutters.

[0063]

According to the gaming machine island of the present invention, since a pair of collecting gutters are provided for collecting gaming media for each gaming machine row, each collecting gutter is smaller in width than the conventional wide collecting gutter. It can be designed to be narrow, and it is possible to secure a wide empty space for arranging other game-related equipment inside the lower island of the island.
In addition, a guide rail that extends in a loop is arranged on the top of the island,
A plurality of transport carts are circulated along the guide rails, and these transport carts are used to supply the game media to each of the gaming machines, so that the replenishment mechanism for the game media can be accommodated without rising high in the upper island. The replenishment of the game media to each gaming machine can be performed reliably and quickly.
