Description

[Detailed description of the invention] (Field of industrial application) The present invention relates to a ball launcher for a pachinko machine that is capable of stabilizing the flight distance of pachinko balls that have different ball diameters. By constructing at least one of the two rotating bodies sandwiched between them and a belt stretched between the pulleys, it is possible to correspond to the difference in the diameter of the pachinko balls, and to make each pachinko ball This invention relates to a ball launcher for a pachinko machine that can stabilize the flight distance of a ball.

(Prior Art) In the specification attached to the patent application filed on July 23, 1980 (Japanese Patent Application No. 59-152731), the inventor proposed that rotating bodies be arranged to face each other, This paper proposes a ball launcher in which a pachinko ball is held between two rotating bodies and the pachinko balls are launched by the rotational force of the rotating bodies.

(Problem that the invention attempts to solve) By the way, the pachinko balls used in pachinko machines are constantly polished to prevent rust from forming on the surface. For this reason, there is a difference in the diameter of the pachinko ball between a new pachinko ball and a frequently used pachinko ball.

This difference in diameter causes the contact between the pachinko ball and the rotating body to change slightly when the pachinko ball passes between the rotating bodies, making it difficult to stabilize the flight distance of the pachinko ball. It was hot. Regarding the batted ball launcher proposed earlier by the present inventor, the distance between the rotating bodies can be changed by moving the rotating bodies, but since the difference in diameter is slight, the spacing can be adjusted to correspond to the difference. It is difficult to make adjustments and the structure of the device becomes complicated.

The present invention was developed in view of these circumstances, and provides a hitting ball in which a pachinko ball is held between rotating bodies that are placed facing each other, and the pachinko ball is launched by the rotational force of the rotating bodies. An object of the present invention is to provide a ball launcher for a pachinko machine that can stabilize the flying distance of pachinko balls having different diameters.

(Means for Solving the Problems) That is, the batted ball launcher according to the present invention holds pachinko balls between rotating bodies arranged to face each other, and uses the rotational force of the rotating bodies to shoot the pachinko balls. The ball launcher is configured to launch a ball, and is characterized in that at least one rotating body is comprised of a pulley and a belt stretched between the pulleys.

(Operation of the invention) As described above, in the ball launcher according to the invention, since at least one of the rotating bodies is provided with a belt, a pachinko ball with a relatively large diameter can pass between the two opposing rotating bodies. When passing, the pachinko balls can be passed by the bending of the belt, and since the belt is stretched, contact between the pachinko balls and the rotating body can be maintained reliably.

(Example) Hereinafter, an example will be described with reference to the drawings. However, the dimensions, materials, shapes, etc. of the components described in this example are not intended to limit the scope of this invention, unless otherwise specified, and are merely illustrative examples. Only.

In the figure, a guide rail 2 for guiding pachinko balls to the game surface of the game board 1 is provided on the front surface of a game board 1 of the pachinko machine. At the base end of the guide rail, rotating bodies 3a and 3b are installed vertically and facing each other.

In this embodiment, the lower rotary body 3b consists of two pulleys 4a provided along the guide rail 2,
4b, and a belt 5 stretched between each pulley 4a, 4b. The belt is maintained in a tensioned state so that it can definitely come into contact with the pachinko balls P passing between it and the rotating body 3a above. The belt 5 is deformed by external force, but returns to its original stretched state when the external force is removed. the pulley 4a,
4b and the upper rotating body 3a are arranged so as not to face each other across the path of the pachinko ball P. Therefore, even a pachinko ball P having a relatively large diameter can be passed between the upper rotating body 3a and the lower rotating body 3b. Note that the material of the belt 5 is not particularly limited. Further, the belt 5 is not limited to a single belt-like body as shown in the embodiment described above, but may be made of a plurality of plate members 8 connected in a belt-like shape as shown in FIG. Any structure may be used as long as it can be stretched between 4b.

The outer periphery of the upper rotating body 3a may be made of any material, but if ceramic is used, which has wear resistance, it can be used for a long time.

Now, to explain the state in which the pachinko ball P is fired in the embodiment, as shown in FIG. 2, when passing between the upper rotating body 3a and the lower rotating body 3b, the pachinko ball P The circumferential portion of the belt 5 is held in a concave state along the shape of P. In the present invention, differences in the diameters of the pachinko balls P can be accommodated by changing the state of the recesses. Further, since the belt 5 is stretched, the pachinko ball P is kept in constant contact with the lower rotating body 3b by the upper rotating body 3a. Therefore, the flight distance of the pachinko ball P can be stabilized.

4 and 5 show other embodiments of the ball launcher according to the present invention, and FIG.
In the figure, the upper and lower rotating bodies 3a and 3b are connected to a pulley 4a,
4b, 6a, 6b, and belts 5, 7 stretched between the pulleys 4a, 4b and between the pulleys 6a, 6b. It is placed in a shifted position. In addition, in FIG.
b and between pulleys 4a and 4b and pulleys 6a and 6b
It is composed of belts 5 and 7 stretched between the upper rotating body 3a and the lower rotating body 3a.
b is formed long along the path of the pachinko ball P.

Note that the lower rotating body 3b is a pulley 4a or 4b.
Although not shown as a rotating shaft, it is driven by a drive motor. In the present invention, the drive motors provided on the rotating bodies 3a and 3b are not limited to those provided on one rotating body 3b, but also on the other rotating body 3b.
It is also possible to have a configuration provided in a and 3b.

(Effect of the invention) As described above, according to the invention, by configuring at least one of the rotating bodies with a pulley and a belt stretched between the pulleys, pachinko balls of different diameters can be placed between two opposing rotating bodies. In addition, the pachinko balls can be kept in reliable contact with the rotating body of the other party. Therefore, the flight distance of the pachinko ball can be stabilized. Furthermore, according to the ball launcher according to the present invention, it is possible to accommodate differences in the diameters of pachinko balls while the position of the rotating body is fixed.
