Description

[Detailed Description of the Invention] The present invention relates to a mounting structure for a game board in a pachinko game machine.

Conventionally, pachinko machines had guide rails set up, nailed in place, and a game board with prize-winning ball chuckers, etc., fastened to the front frame with bolts and nuts. This has the drawback that replacement work is often complicated when changing the design of one or several dozen pachinko game machines.

Therefore, conventionally, as seen in Japanese Utility Model Publication No. 56-26771, a case body having a female cylinder was attached to the front frame (storage frame), a guide hole was provided in the game board into which the case body was inserted, and the guide hole A mounting structure for a game board was devised in which a lock plate is attached to the rear opening edge and a male member for locking and releasing the lock plate is rotatably fitted in the female cylinder. Both the frame and the game board had to be pre-processed, making the manufacturing process time-consuming and costly.

The present invention was made with the aim of eliminating the above-mentioned drawbacks. Namely, jig insertion holes are provided in decorative parts that protrude forward from the surface of the game board at the four corners of the game board that is fitted into the window of the front frame. At the same time as drilling a hole in the front frame at a location corresponding to the jig insertion hole,
Fixing a fixture having a pin part that is rotatable with the same axis as the jig insertion hole, and as the pin part rotates through the jig insertion hole by an appropriate jig, To provide a mounting structure for a game board in a pachinko game machine, in which a holding piece that rotates integrally with the pin part engages with the surface of the game board to fix the game board to the front frame. It is something.

The mounting structure of the present invention having the above structure is simplified as much as possible, and the manufacturing process (work)
The structure is designed to save time and effort in both the replacement work and the replacement work.

Hereinafter, one embodiment of the mounting structure of the game board in the pachinko game machine of the present invention will be explained with reference to the drawings. In the figure, 1 is the front frame of the pachinko game machine,
A window 3 into which a game board 2 is inserted is bored in the center of the front. The window number 3 is formed into an octagonal shape with notches provided at the four corners of a rectangular shape in front, and fittings 9, 9, etc., which will be described later, are attached to the oblique sides 3a, 3a,... of the four corners. Become. The game board 2 has a size that can be fitted into the window 3, and its front face is octagonal to match the window 3, and there are mounting holes between the oblique sides 3a, 3a, . . . of the front frame 1. A gap d (or notch) is provided that allows the tools 9, 9 to be inserted freely. Further, the game board 2 has guide rails 4, nails 5, winning ball checker 6, etc. arranged on its surface, and decorative parts 7, 7... are pasted on the four corners, and the decorative parts 7, 7... Jig insertion holes 8, 8, . . . are bored therein. The decorative parts 7, 7... are attached with the base parts 7a, 7a... perpendicular to the surface of the game board 2, and the base parts 7
a, 7a... are constructed at right angles, that is, parallel to the game board 2, and when viewed from the front, the game board 2 and the four corner decorative parts 7, 7... together form a regular square shape. It becomes like this. As shown in FIG. 3, the fixture 9 has a pin portion 9c rotatably inserted into a hollow cylindrical body 9 having an integrally molded flange 9a, and a hexagonal jig is attached to the front end surface of the pin portion 9c. Insertion hole 9d
A presser piece 9e is inserted perpendicularly to the axis of the pin portion 9c. The fittings 9,9
... is the oblique side 3 of the front frame 1 as shown in Fig. 4.
a, 3a... from the back side with screws 10, and the presser piece 9e is fixed to the pin portions 9c, 9c...
. . , and one presser piece 9e comes to engage with the surface of the oblique side portions 3a, 3a, . The fixtures 9, 9, . . . are fixed at locations where the pin portions 9c, 9c, . . . have the same axis as the jig insertion holes 8, 8, .

In the pachinko game machine constructed as described above, first, the holding pieces 9e, 9e... of the fixtures 9, 9... fixed to the oblique sides 3a, 3a... at the four corners of the front frame 1 are attached to the oblique sides 3a, 3a. ..., and then insert the game board 2 into the window 3 of the front frame 1 (the fourth
), then move the hex wrench 11 to the decorative parts 7, 7...
Mounting tools 9, 9 are inserted through jig insertion holes 8, 8... of...
The pin parts 9c, 9c... are inserted into the jig insertion holes 9d, 9d... to rotate approximately 90 degrees, and the holding pieces 9e, 9e..., which rotate accordingly, are inserted into the game board 2. By engaging with the game board 2
is fixed to the front frame 1 (Fig. 5). At this time, the oblique side portion 3 of the front frame 1
It is desirable that ribs 12 for locking the presser pieces 9e, 9e are provided on the surfaces of the pins 9c, 9c, . According to this mounting structure, it is only necessary to drill the jig insertion holes 8, 8... on the side of the game board 2 where the decorative parts 7, 7... are provided, and the structure can be made extremely simple. Since the holding pieces 9e, 9e... of the fixtures 9, 9... fixed to the front frame 1 are directly engaged with the surface of the game board 2, the fixation of the game board 2 to the front frame 1 is ensured. can do. In addition, since the decorative parts 7, 7 are configured to protrude forward from the surface of the game board 2 and cover the engaging parts (the holding pieces 9e, 9e, . . . with respect to the surface of the game board 2), the engaging parts 7, 7 are simplified. The mating part cannot be hidden from the player, and it is excellent in terms of aesthetic treatment, and furthermore, the positioning of the game board 2 when fitting into the front frame 1 is facilitated.

Since the mounting structure of the game board in the pachinko game machine of the present invention is constructed as described above, when a game board equipped with a decorative part is attached to the front frame, it is not only possible to attach it from the front side of the front frame. This can be easily done by simply rotating the fixture, and its practical effects are extremely high.
