DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a ball tank for storing pachinko balls supplied from a supply path above a pachinko machine and guiding the balls to a pachinko ball dispensing device.

[0002]

2. Description of the Related Art In recent pachinko machines, a starting winning opening, a variable display device, a large winning opening, and the like are arranged on a game board, and when a game ball wins in the starting winning opening, the design of the variable display device is changed. The mainstream is a game having a specific game state (big hit) in which the display at the time of the stop is a predetermined big hit symbol (big hit) and repeating the operation of opening the big winning opening.

On the other hand, a mechanism plate made of a synthetic resin is mounted on the back of the game board so as to be openable and closable, and a circuit hole for suppressing the above-mentioned game contents is provided in a window hole opened substantially at the center of the mechanism board. A substrate box containing the substrates is provided. Also, as is well known, a ball tank and a tank rail communicating with a drop port provided at the bottom of the ball tank are provided on the upper portion of the mechanism plate, and a pachinko ball in the ball tank is connected to the tank rail via the tank rail. It leads to the pachinko ball dispensing device.

Meanwhile, in recent pachinko machines, a large circuit board has been required in accordance with the sophistication of the game content and the like, and a board box for accommodating the circuit board has also been increased in size. As a result, it is becoming difficult to attach the mechanism plate to a window hole. It is thought that such a problem can be easily solved by enlarging the window hole of the mechanism plate. However, the mechanism plate is provided with back parts such as the above-described ball tank, tank rail, and pachinko ball dispensing device. For this reason, the size of the window is limited, and it is impossible to increase the size of the window.

Therefore, in order to solve such a problem, an outlet is formed on one side wall of the ball tank, and a passage for aligning the pachinko balls and guiding the ball to the outlet is formed at the bottom of the ball tank. There has been proposed a configuration in which a tank rail is not required and a window of a mechanism plate can be enlarged (for example, see Japanese Patent Application Laid-Open No. 7-51453).

[0006]

However, in the above-mentioned conventional ball tank, even if the tank rail is not required and the window hole of the mechanism plate can be enlarged, the installation space for the ball is not required. Because there is no ball leveling, the pachinko balls in the ball tank cannot be aligned in a line when the pachinko balls are concentrated from the passage to the outlet, and the ball bites at the outlet. This causes a problem that pachinko balls cannot flow out of the outlet.

Accordingly, an object of the present invention is to form a deep groove-shaped passage section having a concave cross section at the bottom of a ball tank, thereby eliminating the need for a tank rail, and providing a ball leveler at the ball outlet of the ball tank. To provide a ball tank for a pachinko machine that can effectively act on the ball pressure of pachinko balls flowing out of the ball tank and can be aligned and discharged in a line without causing ball clogging. .

[0008]

In order to achieve the above object, a ball tank of a pachinko machine according to the present invention is provided with a rectangular box having an open upper surface at substantially the center of the longitudinal bottom portion from one side. A passage portion having a concave groove shape in section is provided in an inclined manner toward the opposite side surface, and a position slightly forward from the opposite side surface is formed as a ball outlet of the passage portion, and a ball at the bottom of the ball tank is formed. A ball leveling is provided at the exit.

The ball leveling device comprises two members, a support portion and a ball leveling body portion. The support portion has a support shaft provided on a support piece provided integrally with a cylindrical portion having a shaft through hole. The leveling body has an upper support hole communicating with the outside through a cutout through which the support shaft can be inserted, and a horizontal hole for installing the support shaft in the spherical flow path. It is preferable that the shaft is formed to have a diameter larger than the diameter of the shaft, and the shaft through-hole of the support portion is swingably fitted with play on the horizontal axis.

[0010] The mounting member for the ball-leveling is formed to have a mounting portion having an H-shaped cross section, a horizontal axis and a cover portion projecting from a side wall bent from the mounting portion. At the same time, the shaft through hole of the supporting part is swingably freely inserted and installed, and a vertical groove is provided on the side wall of the ball tank, and the mounting part is detachably installed in the vertical groove so that the ball is leveled at the bottom of the ball tank.
