Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a premium ball tank for a pachinko machine.

[0002]

2. Description of the Related Art As is well known, a mechanism board made of synthetic resin is openably and closably attached to the back of a game board of a pachinko machine, and a prize ball tank is attached to the upper part of the mechanism board. There is. Then, the balls of the prize ball tank are guided to the prize ball dispensing device via the tank rail and the curve rail.

[0003]

In the conventional pachinko machine, as shown in FIG. 6, the prize ball tank 10 is used.
The prize ball tank 100 and the tank rail 101 are attached with a space L so that the ball of 0 flows out smoothly into the tank rail 101. Therefore, the flow of the balls on the tank rail 101 is deteriorated due to a ball clogging or the like, and the ball passage 1
When spheres are stacked on 02a to 102c, there is a problem that the spheres fall out from the space L between the prize ball tank 100 and the tank rail 101.

Particularly, in recent pachinko game shops,
A hall computer for management is provided, and for example, a supply ball to the prize ball tank of each pachinko machine that will be a loss for the pachinko game store, and the number of out balls etc. that are profitable to the pachinko game store , And each pachinko machine is managed based on these loss data and profit data. Therefore, if a ball that has flown from the prize ball tank 100 to the tank rail 101 spills outside, the spilled ball will be processed as loss data, and it will not be possible to obtain accurate data for each pachinko machine. There was a problem.

Further, since the tank rail 101 is made of synthetic resin, it is easily deformed, and the front side wall 103 of the tank rail 101 is easily deformed.
However, there is also a problem that the ball passage 102a is narrowed when the game board is bent toward the game board side, resulting in ball clogging.

The present invention has been made in view of the above problems of the prior art, and an object thereof is to prevent ball spill from the tank rail and to prevent the tank rail from bending. It aims to provide a premium ball tank for a pachinko machine that can be used.

[0007]

To achieve the above object, the present invention is a pachinko machine provided with a prize ball tank and a tank rail for aligning the balls of the prize ball tank and guiding the balls to the prize ball dispensing device. In the machine, the prize ball tank
A ball spill prevention plate that is fixed to the upper part of the rear surface and is provided on the lower surface of the bottom of the prize ball tank to reach near the upper edge of the front side wall of the tank rail is provided.

In order to prevent the tank rail from bending, it is effective to provide a catch piece integrally with the ball spill prevention plate and bring the catch piece into contact with the inner surface of the front side wall of the tank rail.

[0009]

The ball spill prevention plate provided on the lower surface of the bottom of the prize ball tank is located at the interval between the prize ball tank and the tank rail, and reliably prevents the ball of the tank rail from spilling to the outside.

Further, the receiving piece provided on the ball spill prevention plate surely prevents the front side wall from being bent toward the game board side by contacting the inner surface of the front side wall of the tank rail.

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, where 1 is a front frame of the pachinko machine, 2 is a game board detachably attached to the back surface of the front frame 1, and 3 is an openable and closable back surface of the game board. It is a mechanism plate made of synthetic resin to be attached to. The prize ball tank 4 is fixed to the upper part of the back surface of the mechanism plate 3. A tank rail 5 is arranged below the prize ball tank 4. The tank rail 5 guides the balls of the prize ball tank 4 to the prize ball payout device 7 via the curved rail 6.

As shown in FIGS. 2 and 3, the prize ball tank 4 is formed in a box-like shape having a substantially rectangular plane with an open top surface. One end of the bottom 8 of the prize ball tank 4 is provided at the upstream end of the tank rail 5. A corresponding outlet 9 is formed.

The tank rail 5 is formed in a gutter shape having an open upper surface by a rear side wall 10 that abuts on the outer surface of the mechanism plate 3, a bottom portion 11 and a front side wall 12, and the bottom portion 11 has partition walls 13a and 13a. Provide three ball passages 14a-1
4c is formed (see FIGS. 4 and 5). Also,
A ball collapsing portion 14 is formed in the upstream portion of the tank rail 5 so as to bulge the front side wall 12 outward and communicate with the ball passage 12a.

On the lower surface of the bottom 8 of the prize ball tank 4, a ball spill preventing plate 15 is integrally provided so as to project. As shown in FIGS. 2 to 4, the ball spill preventive plate 15 is selected to have a length such that the lower end thereof reaches near the upper edge of the front side wall 12 of the tank rail 5, and loosens along the ball collapsing portion 14. It is formed by curving a crab. Also, the ball spill prevention plate 15
A receiving piece 16 that is in contact with the inner surface of the front side wall 12 of the tank rail 5 is bent and formed at an end located on the downstream side of the.

In the premium ball tank 4 of the present invention constructed as described above, as shown in FIG. 4, the ball spill prevention plate 15 is provided between the lower surface of the bottom 8 of the premium ball tank 4 and the upper edge of the front side wall 12 of the tank rail. Positioned in the space between them, the balls of the tank rail 5 are surely prevented from spilling out.

Further, as shown in FIG. 5, the receiving piece 16 formed integrally with the ball spill prevention plate 15 comes into contact with the inner surface of the front side wall 12 of the tank rail 5 so that the front side wall 12 is forward (on the side of the game board).
Be sure to prevent bending. Therefore, the ball passage 13a is not narrowed and the ball is not clogged, and a smooth ball flow is always guaranteed.

[0017]

As described above, the prize ball tank of the pachinko machine according to the present invention can reliably prevent the balls from spilling out even if they are stacked on the ball passage of the tank rail. it can.

Further, it has an excellent effect that the front side wall of the tank rail can be surely prevented from bending forward.
