Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a support structure for a ball leveling member attached to a tank rail of a pachinko machine.

[0002]

2. Description of the Related Art In a conventional pachinko machine, a ball tank is arranged on the upper back surface of a game board, and the pachinko balls of the ball tank are sent to a pachinko ball payout device by a tank rail. Then, as shown in FIG. 6, a horizontal shaft 101 is provided above the tank rail 100, and a spherical leveling member 102 is swingably supported on the horizontal shaft 101. As is well known, if the pachinko balls of the tank rail 100 overlap and flow down, the ball smoothing member 102 receives the overlapped pachinko balls on the side surface and aligns them in a line. Therefore, the ball leveling member 102 is provided with a weight 103 so as to overcome the ball pressure of the overlapping pachinko balls to some extent.

[0003]

By the way, the conventional ball leveling member 102 is rotatably supported by simply inserting the shaft through hole 104 at the upper end of the ball leveling member 102 into the horizontal shaft 101. Therefore, if there are many overlapping pachinko balls, the ball pressure causes the ball leveling member 102 to be pushed and swing, and as shown in FIG. 7, the first and second levels of the pachinko ball and ball leveling member 102. There is a problem that a ball clogging occurs due to a delicate balance between the return force of the weight 103 and a pachinko ball supply to the pachinko ball dispensing device.

The present invention has been made in view of the above problems of the prior art. The object of the present invention is to provide a ball in a tank rail even if a pachinko ball overlaps the tank rail and flows down. It is an object of the present invention to provide a support structure for a ball leveling member attached to a tank rail of a pachinko machine that does not cause a clogging phenomenon.

[0005]

In order to achieve the above object, the present invention provides a horizontal axis above a tank rail for feeding a pachinko ball of a ball tank to a pachinko ball dispensing device, and the horizontal axis is In a pachinko machine in which a ball leveling member is pivotally supported, a diameter of an axial through hole of the ball leveling member to be inserted into the horizontal axis is formed to be larger than a diameter of the horizontal axis, thereby leveling the ball. The member is allowed to freely move within the range of the gap between the horizontal axis and the shaft through hole.

[0006]

With the shaft supporting structure of the ball leveling member configured as described above, when a pachinko ball flowing down overlapping the tank rail comes into contact with the ball leveling member, the ball leveling member changes the condition of the ball pressure. Correspondingly, it randomly floats in the vertical direction or the front-back direction. Therefore, the ball pressure of the pachinko ball flowing down the tank rail is balanced with the restoring force of the ball leveling member, and the ball clogging is less likely to occur, so that the pachinko ball can be smoothly rectified.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the present invention will be described below with reference to the drawings. FIG. 1 is a rear view of a pachinko machine to which the present invention is applied, 1 is a front frame of the pachinko machine, 2 is a front frame 1
A game board that can be detachably attached to the back side of the game board, and 3 is a game board 2
With a mechanism plate made of synthetic resin that is attached to the back of the
A ball tank 4 is fixed to the upper part of the back surface of the mechanism plate 3. Further, below the ball tank 4, there is provided a tank rail 5 that aligns and guides the pachinko balls of the ball tank 4, and the downstream end of the tank rail 5 is connected to a pachinko ball payout device 7 via a bending rail 6. It is connected.

As shown in FIG. 2, the tank rail 5 is formed in a gutter shape with its upper surface opened by a rear side wall 8 and a bottom portion 9 and a front side wall 10 which are in contact with the mechanism plate 3 by a synthetic resin. Is provided with a partition wall 11 in the longitudinal direction to form two ball passages 12, 12. In addition, a horizontal shaft 13 is integrally formed on the back surface of the mechanism plate 3 located above the downstream side of the tank rail 5 so as to be orthogonal to the ball passages 12, 12. The horizontal axis 13 is a ball leveling member 14, which will be described later,
14 is swingably supported, and its protruding length is selected so that the tip of the shaft 14 abuts the inner surface of the front side wall 10 of the tank rail 5.

However, the ball leveling members 14, 14 have a three-dimensional shape substantially equal to the passage width of each of the ball passages 12, 12, and the upper end thereof has a shaft through hole having a diameter larger than the diameter of the horizontal shaft 13. 15 and 15 are provided. Then, the shaft through holes 15 and 15 are inserted into the horizontal shaft 13, whereby the ball leveling members 14 and 14 are inserted into the horizontal shaft 13 and the shaft through holes 15 and 15, respectively.
It is configured so that it can freely move within the range of the gap between them.

Each ball leveling member 14, 14 is formed with an arcuate lower end so as to reduce contact friction with a pachinko ball that flows down in an overlapping manner in the ball passages 12, 12, and the center of gravity is always in the vertical direction. A weight 16 is provided so that The weight 16 is of a size that can overcome the ball pressure of a plurality of pachinko balls. Also, each ball leveling member 1
As shown in FIG. 4, the distance between the lower ends of the balls 4, 14 and the upper surface of the bottom 9 of the tank rail 5 is set so that the pachinko balls flowing down in a row through the ball passages 12, 12 do not contact the ball leveling members 14, 14. Is selected to be slightly larger than the diameter of the pachinko ball.

According to the present invention configured as described above,
Even if a large number of pachinko balls flow down in the ball passages 12, 12 in an overlapping manner and the ball pressure causes the ball leveling members 14, 14 to swing, the ball leveling members 14, 14
5 will randomly move up and down or back and forth as shown by the chain line in FIG. 5 due to the gap between the horizontal shaft 13 and the shaft through holes 15, 15. Alternatively, the pachinko balls and the return forces of the ball leveling members 14 and 14 are balanced so that ball clogging is less likely to occur, and the pachinko balls in the ball passages 12 and 12 can be reliably rectified and flowed down. it can.

In this embodiment, the ball passages 12 of the tank rail 5 are arranged in two rows and the ball passages 12 and 12 are provided with the ball leveling members 14 and 14, respectively. The number of the members may be one as a three-dimensional shape having a width of two rows of spherical passages. Further, in the case where there are three rows of ball passages, a ball leveling member may be provided in each ball passage individually, or a combination of two rows of ball passages and one row of ball passages may be used in combination. Good.

[0013]

As is apparent from the above description, the shaft-supporting structure of the ball leveling member attached to the tank rail of the pachinko machine according to the present invention has a shaft-passing structure of the ball leveling member which is inserted into the horizontal axis. Since the diameter of the hole is formed larger than the diameter of the horizontal axis so that the ball leveling member can be randomly moved up and down or in the front-back direction, even if the pachinko balls flow down in the ball passage of the tank rail, It is less likely to cause clogging, and it is possible to rectify the pachinko balls reliably and smoothly.
