Description

[0001]
[Industrial application fields]
The present invention relates to a tank rail for guiding a pachinko ball of a ball tank to a pachinko ball dispensing device.
[0002]
[Prior art]
Conventionally, as is well known, a mechanism board made of synthetic resin is mounted on the back of the game board of the pachinko machine, and a ball tank is fixed to the upper part of the mechanism board. A tank rail for guiding the pachinko balls of the ball tank to the pachinko ball dispensing device is provided below the ball tank.
[0003]
On the other hand, recently, an electronic pachinko machine called a common CR machine using a card is becoming widespread, and the pachinko ball is paid out by the pachinko ball payout device by electric control.
[0004]
[Problems to be solved by the invention]
By the way, since the tank rail that guides the pachinko ball of the ball tank to the pachinko ball dispensing device is formed of synthetic resin, when the pachinko ball flows down the tank rail, it contacts the inner surface, and static electricity is generated by the friction, This static electricity generates a high voltage and causes a malfunction of the control circuit of the pachinko ball dispensing apparatus.
[0005]
In addition, stagnant heat from the pachinko spheres causes the plastic resin tank rail to bend and dirt to adhere to the inner surface, reducing the rectifying effect of the pachinko spheres and inhibiting the smooth flow to cause clogging of the balls. There was a problem.
[0006]
The present invention has been made in view of such problems of the prior art, and the object of the present invention is to prevent malfunction of the pachinko ball dispensing device due to static electricity and to increase the overall strength of the tank rail. It is an object of the present invention to provide a tank rail for a pachinko machine that allows a pachinko ball to flow smoothly.
[0007]
[Means for Solving the Problems]
In order to achieve the above object, the present invention provides 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, and the pachinko ball can contact the inner surface of the tank rail. A metal plate is provided, and the metal plate is connected to a conductive member of a pachinko machine and grounded.
[0008]
Further, it is preferable that the metal plate is mounted on the inner surface of the front side wall opposite to the rear side wall of the tank rail that contacts the back surface of the game board in order to prevent the tank rail from bending.
[0009]
Further, it is preferable that the metal plate is screwed to the front side wall of the tank rail integrally with the spherical support shaft in order to simplify the mounting operation.
[0010]
[Action]
The tank rail of the pachinko machine configured as described above is configured such that when the pachinko ball flows down the tank rail, static electricity is generated by contact friction, and even if the pachinko ball is stagnated, It is grounded through a conductive member. For this reason, malfunction of the control circuit of the pachinko ball payout device due to static electricity can be prevented.
[0011]
Further, the metal plate mounted on the inner surface of the front side wall of the tank rail functions to effectively dissipate the heat accumulated in the pachinko balls to prevent the tank rail from being bent and to increase the overall strength.
[0012]
In addition, by screwing the metal plate integrally with the spherical support shaft, it is not necessary to screw the metal plate to the tank rail separately, and workability can be improved.
[0013]
【Example】
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 as seen from the rear surface, and FIG. 3 is an exploded perspective view thereof. In the figure, 1 is a front frame of the pachinko machine, 2 is a game board that is detachably attached to the back surface of the front frame 1, and 3 is a synthetic resin mechanism plate that is detachably attached to the back surface of the game board 2. A ball tank 4 is fixed to the upper surface of the rear 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 dispensing device 7 via a bent rail 6, and the pachinko ball dispensed under the pachinko ball dispensing device 7 is placed in front of the hitting ball supply tray ( A discharge rod 8 is provided to lead to (not shown).
[0014]
As shown in FIGS. 2 and 3, the tank rail 5 is formed in a bowl shape having an upper surface opened by a rear side wall 9 that contacts the mechanism plate 3 by a synthetic resin, a bottom portion 10 and a front side wall 11. Is provided with a partition wall 12 in the longitudinal direction to form two ball passages 13a and 13b. Reference numeral 14 denotes a ball smoothing provided above the ball passages 13a and 13b.
[0015]
The pachinko ball dispensing device 7 includes a screw member 16 provided with a spiral 15 for receiving the most advanced pachinko ball of the bent rail 6, a motor 17 for rotating the screw member 16, and a control circuit board 18. The pachinko balls received on the ridge 15 by the rotation of the screw member 16 are discharged one by one to the lower discharge rod 8.
[0016]
Thus, a conductive metal plate 19 is attached to the inner surface of the front side wall 11 of the tank rail 5. The metal plate 19 is temporarily fixed to the front side wall 11 by the bent portions 20, 20 and then fixed to the front side wall 11 with screws 22 integrally with the support shaft 21 of the ball smoothing 14 as shown in FIG. Then, the protruding piece 23 formed on the metal plate 19 is protruded downward from the bottom 10 of the tank rail 5, and one end of the lead wire 24 is connected to the protruding piece 23 by soldering or the like. The end is connected to a reinforcing metal fitting 26 as a conductive member attached to the outer frame 25 of the pachinko machine and grounded. The partition wall 12 gradually increases from the upstream side toward the downstream side so that the pachinko balls of the both ball passages 13a and 13b merge on the upstream side of the tank rail 5 and are aligned in a line as they flow down. It is formed as follows.
[0017]
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 is stagnated in the pachinko ball, the static electricity that has been stagnated via the metal plate 19 and the lead wire 24. Since it flows to the reinforcing metal fitting 26 and is removed, 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 bracket for the game board 2 or a locking bracket for the mechanism plate 3, and is not limited to the reinforcing bracket 26.
[0018]
If the metal plate 19 is attached to the inner surface of the front side wall 11 of the tank rail 5 as in this embodiment, even if the pachinko ball is stagnant, the heat can be effectively radiated by the metal plate 19. In addition, the overall strength can be increased and the tank rail 5 can be prevented from bending.
[0019]
Furthermore, by adopting a configuration in which the metal plate 19 is fixed to the front side wall 11 with the screw 22 integrally with the support shaft 21 of the ball smoothing 14, the metal plate 19 and the ball smoothing 14 can be attached in one behavior. Can improve work efficiency.
[0020]
【The invention's effect】
As described above, according to the present invention, the static electricity generated when the pachinko balls of the ball tank flow down the tank rail can be removed with a simple structure, thereby causing the malfunction of the control circuit of the pachinko ball dispensing device. Can be reliably prevented.
[0021]
In addition, the overall strength of the tank rail can be increased, and a specific effect such as remarkably simplifying the mounting work of the metal plate can be achieved.
