Description

[Detailed description of the invention] <Industrial field of application> The present invention relates to the structure of a ball supply tray for a pachinko machine, and in particular to a pachinko machine that can be used in a variety of combinations of colors without sacrificing strength and rigidity. This relates to a ball tray.

<Prior Art> Conventionally, as a ball tray for a pachinko machine, the one described in Japanese Patent Application Laid-Open No. 60-45369, proposed by the present applicant, is known. This ball tray has a structure in which the ball storage portion of the ashtray is arranged side by side on the left and right.

<Problems to be solved by the invention> In recent years, pachinko games have been equipped with so-called variable display devices that can generate a large number of safe balls in a short period of time and increase the interest of the game when a special prize mode is formed. Pachinko machines have been developed, and such pachinko machines eject a large amount of prize balls in a short period of time. Therefore, a large amount of prize balls accumulate not only in the ball supply tray but also in the ball tray, and the load on the ball tray, which has a cantilever support structure with respect to the front frame, increases significantly.

However, the conventional ball tray described above has an internal space in which small parts are assembled by thin-walled synthetic resin molding, so although the strength and rigidity have been improved to a certain extent, the small parts are made of synthetic resin. Distortion and bending are likely to occur due to the drop in temperature after molding, and when the ball tray itself is assembled, the alignment of the parts may become misaligned, resulting in a decrease in work efficiency, and the parts to be assembled may remain misaligned with each other. If it is forcibly fastened, one of the butt parts may protrude abnormally, resulting in a fatally defective product that could injure the hands and fingers of players. Conventionally, the work of assembling these parts requires an assembly jig, which requires a complicated process. In addition, the design and color of the ball tray can only be changed by two colors at most, which has the disadvantage that it cannot match the colorful color sense of the game machine itself, which is oriented toward primary colors.

<Means for solving the problems> The present invention was proposed in view of the above-mentioned drawbacks of the conventional technology and in response to the conventional demands. We adopted the idea of integrating the ashtray base and ball storage base by laminating and superimposing them vertically with the reinforcing member and the top member, while forming a space, and molded each part into a relatively large structure to eliminate the distortion described above. The entire ball tray retains its strength and rigidity due to the internal space configuration while minimizing bending and bending, and the entire ball tray can be configured in at least three colors in the vertical direction, and the support part and support legs are The purpose is to enable smooth assembly work without causing any misalignment.

The specific structure includes an ashtray base having a first shaft support on one side of the horizontally long contact part that contacts the pachinko machine main body, and a second shaft support on the other side of the contact part and the main bottom surface. A ball storage base having a concave ball storage part with a ball extraction hole in the part thereof is formed in a protruding manner, and
An ashtray storage chamber is formed between the ball storage base and the ashtray base to constitute a main component base, one of the shafts of the ashtray is supported by a first shaft support of the ashtray base,
The other shaft of the ashtray is supported by the second shaft support of the ball storage base, and the ashtray is provided in the ashtray storage chamber so as to be rotatable forward, and an ashtray base reinforcing member is placed on the outer edge of the ashtray base inside the ashtray base. The first upper surface member is locked with the internal space formed, and the first upper surface member is placed on the ashtray base, and the first upper surface member is connected to the supporting legs provided in relation to each other from the ashtray base side. The support part, which has a fitting receiving part formed at its tip to which the leg part fits, is fixed by a fastening member in the fitted state, and the ball storage base reinforcing member is attached to the outer edge of the ball storage base inside the ball storage part. At the same time, the second upper surface member is placed on the ball storage base excluding the upper surface of the recessed ball storage portion, and the second upper surface member is mutually attached from the ball storage base side. The associated supporting leg portion and the supporting portion having a fitting receiving portion formed at the tip thereof into which the supporting leg portion fits are fixed by a fixing member in a fitted state, and the ashtray base and the ball storage are fixed. A reinforcing member and an upper surface member are stacked and superposed vertically to form an integral structure, and a shutter member for opening and closing the ball ejection hole is provided on the back side of the bottom surface of the ball storage portion and is biased so as to normally close the ball ejection hole. It is characterized by being provided as follows.

<Function> This proposal consists of a main component base 2, an ashtray base reinforcing member 1
7. First upper surface member 20, ball storage base reinforcing member 3
2. Molding the second upper surface member 33 individually. Since each of these members is configured as a relatively large frame, distortion and bending during molding are unlikely to occur. Attach the ashtray to this main component base, place the intermediate parts of the ashtray base reinforcing member and the ball storage base reinforcing member, and further place the first and second upper surface members from above, respectively. , the structure is stacked in the vertical direction, and the tip end of the support leg fits into the fitting receiving part of the support part. This eliminates the inconvenience that the abutting portions between the members are abutted against each other with some deviation and are stuck in an abnormally protruding state, which is the case with the conventional structure in which no fitting portion is provided. Main component base,
By molding each reinforcing member and each upper surface member in different colors, the entire ball tray can be colored in three colorful colors in the vertical direction.

In order to attach the ball tray 1 having the above-described configuration to the pachinko machine main body, the penetrating fixing member 9 protruding from the main component base 2 is attached to the decorative plate 65 on the front of the pachinko machine.
Decorate by inserting a nut (not shown) into the male thread at the tip of the penetrating fixing member 9 which is inserted into the through hole opened in the front frame 66 and into the through hole opened in the front frame 66 and protruded from the back side of the front frame. The plate 65 and the front frame 66 are fastened and fixed. When attached in this manner, the expanded ball outlet 68 of the connection gutter 67 opened in the decorative plate 65 communicates with the ball storage portion. Therefore, during the game, the expansion ball exit 6
Balls discharged from the ball storage section 3 can be stored in the ball storage section 3, such as balls overflowing from the ball supply tray 69 and Far balls. When exchanging these game balls for prizes or moving them to another pachinko machine, the shutter member 41 is coiled by hooking the finger on the finger hook 50 protruding forward of the ball storage section 3 and the operating lever 40. It operates against the bias of the spring 43 to open the ball removal hole 38. Ball extraction hole 3
8, the ball extraction hole 38 and the cylindrical ball guide member 48 communicate with each other to form a ball guide path. Therefore, the balls in the ball storage section 3 flow down within the ball guide path while being regulated in the direction of flow by the cylindrical ball guide member 48. Therefore, the ball that falls from the ball extraction hole 38 is
All of the balls are stored in a ball receiving box 70 prepared in advance below the ball storage part 3 without scattering during the fall.

In addition, in this embodiment, as shown in FIG. 4, the inner peripheral surface of the ball extraction hole 38 is slightly reduced in diameter downward, and the diameter D of the ball extraction hole 38 is made smaller than an integral multiple of the ball diameter d (nd<D<(n+1)d; n is a natural number), forming
Moreover, the thickness step H corresponding to the depth of the ball extraction hole 38 is set to less than half the ball diameter d (H<d/2). Therefore, when a plurality of balls accumulate in the ball storage part 3, there is a gap c smaller than the balls between the ball A placed on the shutter member 41 and the edge of the ball removal hole 38 at the ball removal hole 38. is necessarily formed, and above this gap c, a ball B is formed which is supported by the ball A on the shutter member 41 and the ball extraction hole 38 and is in an unstable state. That is, in the vicinity of the ball extraction hole 38, the heights of the contact points where the balls come into contact with each other are varied to prevent the so-called bridging phenomenon between the balls from occurring. Therefore, when the shutter member 41 is moved to open the ball extraction hole 38, the shutter member 4
Ball A, which was placed directly on ball 1, falls first, and then ball B, which was supported in an unstable state, and other balls around ball extraction hole 38 flow down. As a result, ball clogging does not occur.

Note that the ball extraction mechanism is not limited to the above embodiment, and may have any configuration as long as it can open and close the ball extraction hole of the ball storage portion of the shutter member.

<Effects of the invention> As explained above, according to the invention, each reinforcing member and each upper surface member are vertically connected to the main component base having an ashtray storage chamber between the ashtray base and the ball storage base. Since the ashtray is formed in a laminated structure and has an internal space, it is possible to simplify the mounting structure of the ashtray, and it is also possible to increase the size of the ball tray without sacrificing the strength and rigidity of the ball tray itself. It becomes strong enough to store the balls of
This ball tray is suitable for pachinko machines with variable display devices that have become popular recently.

In particular, since the main component base, each reinforcing member, and each upper surface member can be made individually and a frame structure of relatively large components can be adopted, distortion, bending, warping, etc. can occur when molding these components. This eliminates the misalignment of the mating parts between the parts compared to conventional models, and by adopting a fitting structure between the support part and the support legs, the work of assembling each part is made easier. This can be done smoothly. Therefore, it is possible to prevent the player's hands and fingers from being injured by the ball tray in which either one of the abutting portions protrudes abnormally, unlike in the conventional ball tray. Furthermore, by molding the main component base, each reinforcing member, and each upper surface member in different colors, it is possible to provide a ball saucer that is full of colorful colors and is in keeping with the times.
