DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a metal bell disposed on a prize ball discharge gutter of a pachinko machine.

[0002]

2. Description of the Related Art As is well known, this kind of metal bell is
The sound is generated by colliding the pachinko balls paid out from the pachinko ball payout device to the prize ball discharge gutter to generate a sound, and the sound informs the player that the prize ball has been paid out.

The conventional bell is formed in a cylindrical shape with a bottom as shown in FIG.
1 is bored, the shaft hole 101 is rotatably fitted to a support shaft 103 protruding from the bell mounting surface of the prize ball discharge gutter 102, and then screwed 105 via a washer 104. .

[0004]

The above-mentioned conventional bell 10
No. 0 is formed integrally by press working, so that the shaft hole 101 is inevitably burred or has a sharply edged peripheral portion.

On the other hand, since the support shaft 103 into which the shaft hole 101 of the bell 100 is fitted is made of synthetic resin integrally with the prize ball discharge gutter 102, when the prize ball collides and the bell 100 rotates, the shaft hole 101 is closed. The support shaft 103 is shaved by burrs or the like, and becomes thin or broken. When the support shaft 103 becomes thinner, the bell 100 becomes loose or cannot rotate smoothly, so that the sound becomes smaller or worse. Also,
When the support shaft 103 is broken, there is a serious problem that the entire mechanism plate on which the prize ball discharge gutter 102 is formed needs to be replaced.

SUMMARY OF THE INVENTION The present invention has been made in view of the above-mentioned problems of the prior art. It is an object of the present invention to prevent a spindle from being cut off by rotation of a bell and to remove a bell. It is intended to be able to be mounted in a stable state.

[0007]

In order to achieve the above-mentioned object, the present invention provides a prize ball discharge gutter having a supporting shaft integrally provided on a bell mounting surface thereof through a pedestal having a predetermined height, and a metal bell. A cylindrical edge is provided on the periphery of the shaft hole, a cylindrical edge of a metal bell is fitted on the support shaft, and a support shaft protruding from the cylindrical edge of the metal bell is integrally provided on the back cover plate. The metal bell is mounted on the support shaft by being received in the fitting blind hole of the cylindrical body.

[0008]

In the pachinko machine bell constructed as described above, since the cylindrical edge of the shaft hole comes into contact with the support shaft, the support shaft is shaved and thinned or broken. Disappears. In addition, the bell can be attached to the support shaft in a stable state, and functions to ensure smooth rotation.

[0009]

An embodiment of the present invention will be described below with reference to the drawings. First, a pachinko machine equipped with a bell according to an embodiment of the present invention will be described with reference to FIG. In FIG. 1, 1 is a side frame of a pachinko machine, 2 is a front frame mounted on the front of the side frame 1 so as to be openable and closable, 3 is a game board detachably mounted on the back of the front frame 2 and 4 is a game board. 3 is a mechanism plate made of a synthetic resin, which is attached to the back of the device 3 so as to be freely opened and closed.

FIG. 2 is a perspective view of the mechanism plate 4, and a premium ball tank 5 is fixed to an upper portion of the rear surface of the mechanism plate 4.
Below the prize ball tank 5, a tank rail 7 for aligning the prize balls and guiding them to the pachinko ball payout device 6 is provided. Below the pachinko ball payout device 6, when the premium ball is filled with the premium ball discharge gutter 8 and the hit ball supply tray which guide the paid premium ball to the hit ball supply tray (not shown) on the front of the front frame 2. An overflow gutter 9 is formed to allow excess prize balls from the hitting ball supply tray to overflow into a ball storage tray (not shown). The prize ball discharge gutter 8 and the overflow gutter 9
3 is formed in a gutter shape with an open rear surface as shown in FIG. 3, and a back cover plate 10 is detachably mounted on the upper surface thereof.

The metal bell 11 according to the present invention is disposed on the prize ball discharge gutter 8, and the bell 11 is formed into a cylindrical shape with a bottom by pressing as shown in FIGS. A shaft hole 13 is formed at the center of the bottom portion 12, and a cylindrical edge portion 14 protruding inward is formed integrally with a peripheral edge of the shaft hole 13, and is formed by the cylindrical edge portion 14. The shaft hole 13 is formed in a cylindrical shape.

On the other hand, as shown in FIG. 6, a support shaft 16 is integrally provided on a bell mounting surface 8a of the prize ball discharge gutter 8 via a base 15 having a predetermined height. A cylinder 17 corresponding to the support shaft 16 is provided integrally with the inner surface of the back cover plate 10 in a state where the back cover plate 10 is mounted, and the support shaft 16 is received at the tip of the cylinder 17. Blind hole 1 for drilling
8 are formed.

FIG. 7 is a sectional view showing a state in which the bell 11 according to the present embodiment is mounted on the bell mounting surface 8a of the prize ball discharge gutter 8, and the mounting is performed by first setting the shaft hole 13 of the bell 11 to a support shaft. 16
On the back cover plate 1
0 is attached to the upper surface of the prize ball discharge gutter 8, and the tip of the support shaft 16 protruding from the cylindrical edge 14 of the bell 11 is received in the fitting blind hole 18 of the cylinder 17.

The metal bell 11 according to the present embodiment constructed as described above has a cylindrical edge 14 of the shaft hole 13 and a support shaft 16.
Therefore, the support shaft 16 is not sharpened and broken or broken at all. The bell 11 fits and supports the cylindrical edge portion 14 on the support shaft 16, and also fits the support shaft 16 protruding from the cylindrical edge portion 14 into the cylindrical body 17 provided integrally with the back cover plate 10. Since it is configured to be received in the hole 18, it can be mounted on the support shaft 16 in a stable state, and the sound effect can be enhanced.

[0015]

As apparent from the above description, the pachinko machine bell according to the present invention has a support shaft provided on a bell mounting surface of a prize ball discharge gutter through a pedestal having a predetermined height. A cylindrical fitting portion formed around the shaft hole of the metal bell is fitted to the support shaft, and a support shaft projecting from the cylindrical edge of the metal bell is integrally provided on the back cover plate. The conventional problem that the synthetic resin support shaft that rotatably supports the bell is shaved by the cylindrical edge of the bell and becomes thin or breaks easily. Its practical value is extremely high, for example, it can be reliably eliminated with a simple structure and can be mounted in a stable state with respect to the support shaft.
