Description

[Detailed description of the invention] (Field of industrial application) The present invention is a ball launching device for a pachinko machine that uses the rotational force of a rotating body, and is capable of reliably transmitting the rotational force to the pachinko ball. This article relates to a ball firing device that can be used for a long period of time by reducing friction caused by pachinko balls, and the gist is that a large number of small rotating bodies are provided on the outside of a large rotating body.

(Prior art) Conventionally, ball launchers using a rotating body include:
There is one described in Utility Model Application Publication No. 59-102085. In this device, a rotating body driven by a motor is installed at a predetermined distance from the guide rail. Pachinko balls passing on the guide rail are held between the rotating bodies, and the rotational force of the rotating body launches the pachinko ball. I'm starting to let them do it.

Furthermore, in Japanese Patent Application No. 152,731/1984, the present inventor proposed a method in which rotating bodies are arranged to face each other and pachinko balls are sandwiched between the rotating bodies.
There is a ball firing device that fires pachinko balls using the rotational force of a rotating body.

(Problem to be solved by the invention) By the way, in the case of a ball launching device using such a rotating body, the rotational force of the rotating body is applied to the pachinko ball by the rotation between the rotating body and the guide rail, or between the rotating bodies. This is due to instantaneous contact between the pachinko ball and the rotating body at the point where both are closest. However, since a pachinko ball itself is not a perfect sphere and has an irregular shape, if an attempt is made to launch the pachinko ball through contact as described above, the rotating body may not be able to reliably catch the pachinko ball. In particular, this is because the contact is instantaneous. For this reason, there was a problem that the flight distance of the pachinko balls varied.

In this regard, the present invention aims to ensure the transmission of the rotational force of the rotating body by maintaining the contact state between the rotating body and the pachinko ball for as long as possible, thereby ensuring the transmission of the rotational force of the rotating body to the pachinko ball. It is an object of the present invention to provide a ball launching device for a pachinko machine that can reliably transmit rotational force.

(Means for solving the problem) That is, the ball firing device according to the present invention has a plurality of small rotating bodies provided outside a large rotating body, and a pachinko ball is sandwiched between the large rotating body and the small rotating bodies. The machine is characterized in that the pachinko balls are launched by the rotational force of the rotating body. In addition,
The term "large rotating body" and "small rotating body" refer to rotating bodies having relatively different diameters, and the numerical values of the diameters are not specifically limited.

(Function of the invention) As described above, the present invention forms a pachinko ball path that holds the pachinko balls along the outer periphery of the large rotating body by providing a plurality of small rotating bodies outside the large rotating body, This allows the pachinko ball to maintain contact with the large rotating body for a long time. Therefore, in the present invention, the pachinko balls are not ejected by instantaneous force, but are ejected by being accelerated while passing through the passage, and the pachinko balls are This ensures reliable transmission of the rotational force of the rotating body to the rotating body.

(Example) Hereinafter, an example will be described with reference to the drawings. However, the dimensions, materials, shapes, etc. of the structural parts described in this example are not intended to limit the scope of this invention to these unless otherwise specified, and are merely illustrative examples. It's nothing more than that.

In the figure, the ball launcher in this embodiment consists of a large rotating body 2 installed in front of a game board 1.
, and a pachinko ball P is placed outside the large rotating body 2.
A plurality of small rotating bodies 3 are installed at opposite positions across a passage through which the rotating bodies 3 can pass. The upper part of the small rotating body 3 is connected to a supply port 4 through which pachinko balls P are supplied, and the lower part of the small rotating body 3 is connected to a guide rail 5 that guides the pachinko balls P to the game surface of the game board 1. . Therefore, the pachinko ball P supplied from the supply port 4 is a small rotating body 3
The large rotating body 2 driven by a drive motor 6 applies rotational force to the large rotating body 2, and the large rotating body 2 is guided to the guide rail 5, and further to the game surface.

In the present invention, it is desirable that the small rotating body 3 has a diameter as small as possible in order to allow the pachinko balls P to pass through smoothly. Further, as shown in FIG. 2, tapered guide rails 7 may be provided on both sides of the small rotating body 3 to maintain the directionality of the pachinko balls. In this case, guide rail 7
It is also possible to have a structure in which a plurality of small rotating bodies 3 are integrally provided. In addition to the structure shown in the embodiment shown in FIG. 1, the small rotating bodies 3 may also have an upper gap between the small rotating bodies 3 (A in the figure) as shown in FIG.
It is also possible to have a structure in which a plurality of small rotary bodies 3 are connected as a whole by embedding the parts) with separate members. Furthermore, the term "smaller rotating body 3" is used to distinguish the relative size difference from the larger rotating body 2, and is specifically limited to a diameter of more than or less than a certain number of centimeters. It is not something that can be done. Therefore, in the present invention, as shown in FIG. 4, the diameter is smaller than the diameter of the large rotating body 2, but the small rotating bodies 3 have different diameters, and these small rotating bodies 3 are arranged alternately in size. Good too.

In this embodiment, as shown in FIG. 2, the rotating shaft 8 of the small rotating body 3 is held from below by a spring 9. As a result, when pachinko balls P with different diameters pass between the large rotating body 2 and the small rotating body, the difference in diameter of the pachinko balls P is adjusted to the position of the small rotating body 3 by the expansion and contraction of the spring 9. We are now able to adjust and respond accordingly.

The small rotating body 3 and the large rotating body 2 are made of metal,
The material is not particularly limited, such as synthetic wood, ceramics with excellent wear resistance, etc., and each rotating body 2, 3
A rubber band or the like may be fitted around the outer periphery.

(Effect of the invention) According to the ball firing device according to the invention, by providing a plurality of small rotating bodies on the outside of the large rotating body, a path for pachinko balls held between the large rotating body and the small rotating bodies is provided. By forming a long pachinko ball and maintaining contact between the pachinko ball and the large rotating body,
To reliably transmit the rotational force of a rotating body to a pachinko ball.

Furthermore, according to the ball firing device according to the embodiment, when a rotational force is applied to a pachinko ball, the pachinko ball is held between a large rotating body and a small rotating body, so the friction caused by the pachinko balls can be reduced. , the ball launcher can be used for a long time.
