Description

[Detailed description of the invention] This invention is a pachinko machine with a rolling ball plate that is installed so that only the rolling ball plate can be replaced, and the other parts are installed in a game hall and can be used as many times as needed. Positioning and fixing to the front frame,
It is designed to be compatible and accurate,
A rolling ball plate support frame with an open front is attached to the back of the front frame of a pachinko machine, which has a hinged glass frame that can be opened and closed freely.
In a pachinko machine in which the glass frame is opened and the rolling ball plate is freely inserted into the support frame, a positioning engagement portion is provided on one side of the inner surface in the left and right direction of the rolling ball plate support frame, and a positioning engagement portion is provided on the other side. A locking device for pressing the fitted rolling ball plate in the direction of the positioning engagement part is installed on the inner surface of the ball plate, and a locking part that fits into the positioning engagement part is installed on one end surface of the rolling ball plate. established,
The positioning engagement part and the locking part each have a protrusion on one side;
The other is characterized by being formed with a recessed portion to form a male-female relationship.

Ball rolling plates, which often have to be replaced due to aging due to hitting balls or obsolescence of the design, are already being attached to pachinko machine frames with a long lifespan so that they can be replaced. . In this type of pachinko machine, each part of the front and back sides and the ball rolling plate are precisely aligned, and the balls hit with a durable hitting mallet are hit onto the circular rail of the rolling ball plate. It is necessary to divert the safe balls, out balls, etc. generated by the plate to the durable backing part. The purpose of the present invention is to create a structure that accurately satisfies these requirements, and it is an improvement that simplifies the structure for positioning the rolling ball plate and also provides precise compatibility. It is what you do.

A preferred embodiment of the present invention will be described with reference to the accompanying drawings.

FIG. 1 is a front view of a pachinko machine 1, in which a wide window hole 3 is provided in the front frame 2, which is attached to the main body frame (not shown) so that it can be opened and closed freely in the form of a door. The glass frame 4 fitted with 5 is hinged so that it can be opened and closed freely (the front frame 2 and the glass frame 4 are locked so that the player cannot freely open and close it).

On the back side of the glass frame 4, a rolling ball plate support frame 6 whose front side is open toward the window hole 3 is fixed to the back side of the front frame 2.

The support frame 6 has a pocket 7 roughly equal to the window hole 3 (see FIG. 3), but the lower part is filled with the lower edge 3a of the window hole 3 as shown in the figure, and the upper part is filled with the lower edge 3a of the window hole 3 as shown in the figure. Expand only the filter 7a upward. This support frame 6 is left open except for the rear edge 8, and a plate (not shown) on which many back parts are attached is placed here.

A plurality of protruding positioning engagement parts 9 are fixed to one side 6a in the left-right direction of the support frame 6, and a shaft 10 is provided on the other side to freely rotate about 90 degrees on the inner surface 6b. A locking device 12 consisting of a metal fitting 11 having a diameter of 10 mm is provided, and the lock surface is directed upward when the lock is opened, as shown in FIGS. 4 and 5.

The height of the rolling ball plate 13 is slightly higher than that of the window hole 3, and the width roughly matches the width of the window hole 3, and the locking device 12 is locked as shown in FIGS. When it is in the open state, the rolling ball plate 1
3 is not caught on the metal fitting 11. This rolling ball plate 13 is provided with a recessed engagement portion 14 that fits into the positioning engagement portion 9 described above on one side, and a notched groove 15 on the other side.

In the above embodiment, as shown in FIG. 5, the glass frame 4 is opened to expose the window hole 3, and the rolling ball plate 13 is fitted into the rolling ball plate support frame 6 through the window hole 3, and then inserted into the window hole. 3 to make the locking part 14 correspond to the positioning engagement part 9. Then, the metal fitting 11 of the locking device 12 is rotated in the direction of the arrow in FIG. Pressing the plate 13 in the direction of the positioning engagement part 9 thereby
The fitting between the locking portion 14 and the locking portion 14 is made tight.

The positioning engagement part 9 is a recessed hole, and the engagement part 1
4 may be formed into a protruding shape, and even if the rolling ball plate 13 is replaced as described above, the tightness maintaining function of the engagement will not change.

As described above, the present invention allows the mounting and replacement of the rolling ball plate 13 by simple operations, and furthermore, the rolling ball plate 13 is pressed in the direction of the positioning engagement portion 9 by the locking device 12. , the positioning engagement part 9 and the locking part 14 are tightly fitted together, and the ball plate 3 is tightened so that it does not move up and down and in the front and rear. By simply installing it at the same position on the ball plate 13, it is possible to improve the compatibility of the rolling ball plate 13, making it easy to replace it when necessary.The structure is extremely simple, so it does not meet the specified standards. This has the advantage that a large number of rolling ball plates 13 can be manufactured.
