DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a mounting base plate for a hitting ball firing device for firing a game ball into a game area of a pachinko game machine.

[0002]

2. Description of the Related Art A driving motor for operating a hitting rod is activated by rotating an operating handle while touching a touch plate of a hitting / launching operating handle device, and the hitting rod is rotated by the degree of turning the operating handle. In the conventional ball launching device of a pachinko game machine in which the hitting force of the ball can be adjusted and the game ball can be launched into a desired game area of the game board, a mounting base plate for mounting various components constituting the ball launching device is provided. In this method, a flat iron plate is formed into a predetermined mounting base plate shape by press molding. Therefore, the proportion of the weight of the entire hitting ball launching device is large, and the dimensional accuracy for a predetermined dimension is ± 0.3 mm to ± 0.3 mm.
It was 0.5 mm and the dimensional error was extremely large.

Further, as described above, the weight of the mounting base plate itself becomes heavy and the overall weight becomes extremely heavy, and such a hit ball launching device is placed at a predetermined position on a wooden front frame constituting a pachinko game machine. In order to firmly attach, a large number of attachment parts must be provided, and the attachment process becomes complicated, and the attachment work requires time.

Further, when various components are mounted on the mounting base plate, an error occurs in the dimensional accuracy, which causes a variation in the firing accuracy, and a normal firing is performed for the pachinko parlor and the game player. It has been difficult to provide a highly reliable pachinko gaming machine that can be played in a state.

On the other hand, since the mounting base plate of the conventional hitting ball launching device is formed by press molding, the mounting base plate itself is simply flat. For this purpose, various components and various mounting members (for example, the bearing house 41 shown in FIG. 5) to be mounted on the flat mounting base plate are purchased from many different component specialists depending on the material and the like. In addition to having to assemble as a ball launcher, many single parts were purchased, resulting in a large number of parts, making the assembly process complicated and complicated, and also complicated in parts management. This was causing the cost to increase.

Further, as shown in FIG. 5, in a conventional hitting ball launching device, a component 4 of the adjusting operating device is used to adjust and control the biasing force of the coil spring when it is not in the operating state.
Although the adjusting operation device 46 consisting of 2, 43, 44, and 45 was provided, it was hardly used and was functionally unnecessary. At the same time, the conventional hitting and firing apparatus is provided with stoppers 50 and 54 to stop the hitting rod from rotating in the opposite direction to the hitting and firing direction at a predetermined position. It was an unnecessary device.

[0007]

In view of the above situation,
In the ball launching device of the pachinko gaming machine of the present invention, by changing the material of the mounting base plate and the forming method, the weight is reduced and the dimensional accuracy in forming and mounting is improved. An object of the present invention is to provide a mounting base plate for a hit ball launching device of a pachinko game machine having a structure in which the number of single components is reduced as much as possible and assembly is facilitated.

[0021]

As described above, in the hit ball launching apparatus of the pachinko game machine according to the present invention, the mounting base plate for mounting various parts is integrally formed by injection molding with magnesium alloy, thereby making the conventional iron plate. Since there is no error in the dimensional accuracy compared to the mounting base plate by press molding, it is possible to mount with high accuracy even in the mounting work of various parts and the mounting work on the back of the pachinko machine,
Variations in firing accuracy, which has been a problem in the past, can be eliminated, and a highly reliable pachinko gaming machine can be provided to pachinko parlors and gamers.

In a conventional mounting plate made by press forming an iron plate, since the forming conditions are limited, it is necessary to form a mounting member for mounting various components by itself and fix the mounting member to the mounting plate. However, the mounting member and the mounting base plate can be integrally formed by the injection molding of the present invention, so that the number of parts can be reduced, and the manufacturing process and the parts management can be simplified.

The various components constituting the hitting and launching device are also extremely effective in disposal and recycling because the hitting and launching device itself is assembled from magnesium alloy components by molding as much as possible by the injection molding of the present invention.
