Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a tank rail for guiding a pachinko ball of a ball tank to a pachinko ball dispensing device.

[0002]

2. Description of the Related Art Conventionally, as is well known, a mechanism board made of synthetic resin is mounted on the back surface of a game board of a pachinko machine, and a ball tank is fixed to the upper part of the mechanism board. Further, a tank rail for guiding the pachinko ball of the ball tank to the pachinko ball payout device is provided below the ball tank.

On the other hand, recently, the popular name CR using a card is used.
Electronic pachinko machines called machines are becoming widespread, and pachinko ball payout by a pachinko ball payout device is also performed by electrical control.

[0004]

By the way, since the tank rail for guiding the pachinko ball of the ball tank to the pachinko ball dispensing device is made of synthetic resin, the pachinko ball comes into contact with the inner surface of the tank rail when flowing down the tank rail. There is a problem that static electricity is generated due to the friction, and this static electricity generates a high voltage, which causes the control circuit of the pachinko ball dispensing device to malfunction.

Further, due to the heat retention of the pachinko ball, the tank rail made of synthetic resin is easily bent or dirt is easily attached to the inner surface, the rectifying effect of the pachinko ball is lowered, and smooth flow is obstructed to cause ball clogging. There was a problem such as causing it.

The present invention has been made in view of the above problems of the prior art, and its purpose is to prevent malfunction of the pachinko ball dispensing device due to static electricity and to improve the overall strength of the tank rail. The purpose of the present invention is to provide a tank rail for a pachinko machine in which the pachinko ball can be smoothly flowed down by raising the height.

[0007]

In order to achieve the above object, the present invention is a tank rail for guiding a pachinko ball of a ball tank provided on the back surface of a game board to a pachinko ball dispensing device, the tank rail. Is provided with a metal plate with which a pachinko ball can come into contact, and the metal plate is connected to a conductive member of a pachinko machine to be grounded.

The metal plate is preferably attached to the inner surface of the front side wall opposite to the rear side wall of the tank rail that abuts the back surface of the game board in order to prevent the tank rail from bending.

Further, it is preferable that the metal plate is screwed to the rear side wall of the tank rail integrally with the support shaft for leveling the ball in order to simplify the mounting work.

[0010]

[Function] The tank rail of the pachinko machine configured as described above has a function that when the pachinko ball flows down the tank rail, static electricity is generated due to the contact friction, and the static electricity generated by the pachinko ball is not It is grounded through the metal plate and the conductive member. Therefore, malfunction of the control circuit of the pachinko ball payout device due to static electricity can be prevented.

Further, the metal plate mounted on the inner surface of the front side wall of the tank rail effectively dissipates the retained heat of the pachinko ball to prevent the tank rail from bending and to increase the overall strength.

Further, by screwing the metal plate integrally with the ball-supporting support shaft, it is not necessary to screw the metal plate to the tank rail separately, so that workability can be improved.

[0013]

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 equipped with a tank rail according to the present invention, FIG. 2 is a perspective view of the tank rail of one embodiment of the present invention seen from the rear surface, and FIG. 3 is an exploded perspective view thereof. In the figure, 1 is a front frame of a pachinko machine,
2 is a game board that is detachably attached to the back side of the front frame 1,
Reference numeral 3 denotes a mechanism plate made of synthetic resin, which is attached to the back surface of the game board 2 so as to be openable and closable. A ball tank 4 is fixed to the upper part of the back surface of the mechanism plate 3, and a tank rail 5 is provided below the ball tank 4. Further, the downstream end of the tank rail 5 is connected to a pachinko ball payout device 7 via a bending rail 6, and below the pachinko ball payout device 7, the paid pachinko ball payout plate ( A drain gutter 8 leading to a not shown) is provided.

As shown in FIGS. 2 and 3, the tank rail 5 is formed in a gutter shape whose upper surface is opened by a rear side wall 9 and a bottom portion 10 and a front side wall 11 which are in contact with the mechanism plate 3 by a synthetic resin. The bottom 10 has a partition wall 1 in the longitudinal direction.
2, two ball passages 13a and 13b are formed. Reference numeral 14 is a sphere smoother provided above the ball passages 13a and 13b.

The pachinko ball dispensing device 7 comprises a bent rail 6
Has a screw member 16 spirally provided with a ridge 15 for receiving the most advanced pachinko ball, a motor 17 for rotating the screw member 16 and a control circuit board 18, and the ridge 15 is rotated by the rotation of the screw member 16. The received pachinko balls are discharged one by one to the discharge gutter 8 below.

Thus, the front side wall 1 of the tank rail 5 is
A conductive metal plate 19 is attached to the inner surface of 1. This metal plate 19 is temporarily fixed to the front side wall 11 by the bent portions 20 and 20, and thereafter, as shown in FIG.
Is integrally fixed to the rear side wall 9 with a screw 22. Then, the protruding piece portion 23 formed on the metal plate 19 is made to protrude downward from the bottom portion 10 of the tank rail 5, and one end of the lead wire 24 is connected to the protruding piece portion 23 by soldering or the like. The end is grounded by connecting it to a reinforcing metal fitting 26 as a conductive member mounted on the outer frame 25 of the pachinko machine. The partition wall 12 gradually increases in height from the upstream side to the downstream side so that the pachinko balls in both ball passages 13a and 13b merge on the upstream side of the tank rail 5 and are aligned in a line in order as they flow down. Is formed.

Therefore, even if the pachinko ball flowing down the tank rail 5 comes into contact with the tank rail 5 and the static electricity generated by the friction thereof is stored in the pachinko ball, the stored static electricity is the metal plate 19 and the lead wire 24. Since it is removed by flowing to the reinforcing metal fitting 26 via the, it is possible to reliably prevent malfunction of the control circuit of the pachinko ball dispensing device 17 due to static electricity.
The conductive member may be, for example, a fixing metal fitting of the game board 2 or a locking metal fitting of the mechanism plate 3, and is not limited to the reinforcing metal fitting 26.

Further, as in this embodiment, the tank rail 5
If the metal plate 19 is attached to the inner surface of the front side wall 11 of the, even if the pachinko ball is stagnant, the heat can be effectively dissipated by the metal plate 19 and the overall strength can be increased. Bending of the tank rail 5 can be prevented.

Further, by adopting a structure in which the metal plate 19 and the support shaft 21 of the ball leveling member 14 are integrally fixed to the front side wall 11 by the screw 22, the metal plate 19 and the ball leveling member 14 can be attached in one movement. It can be performed and the work efficiency can be improved.

[0020]

As described above, according to the present invention, the static electricity generated when the pachinko ball of the ball tank flows down the tank rail can be removed with a simple structure, and thereby the pachinko ball dispensing device. The malfunction of the control circuit can be reliably prevented.

Further, it is possible to enhance the overall strength of the tank rail, and to remarkably simplify the work of attaching the metal plate.
