Description

[Detailed description of the invention] (Field of industrial application) This invention not only can withstand long-term use without wear or damage to the guide rail, but also securely holds pachinko balls, thereby making it possible to play pachinko. This is a ball launcher for a pachinko machine that improves the direction of ball launch.The gist of the device is to pass a pachinko ball between rotating bodies that are placed facing each other, and then use the rotational force of the rotating bodies to launch the pachinko ball. This ball firing device is characterized in that a holding groove for holding pachinko balls is provided on the outer periphery of at least one of the rotating bodies.

(Prior art) Conventionally, ball launchers using a rotating body include:
There is one described in Utility Model Application Publication No. 59-102085. This is a rotating body driven by a motor installed at a predetermined distance from the guide rail.
A pachinko ball passing on a guide rail is sandwiched between rotating bodies, and the rotational force of the rotating body applies ball launching force to the pachinko balls.

(Problem to be Solved by the Invention) According to this ball launcher, the pachinko ball is sandwiched between the base end of the guide rail and the rotating body, and is then pushed along the guide rail by the rotational force of the rotating body. fired. Therefore, the pachinko balls are frequently pressed strongly against the base end of the guide rail by the rotating body,
This causes the proximal end of the guide rail to become worn or damaged within a short period of time, necessitating replacement of the guide rail.

In addition, in the case of a conventional ball launcher, pachinko balls are
Pachinko balls are held poorly because they are held by only one point of contact with the rotating body and the guide rail.
There is a problem in that the rotational force of the rotating body cannot be transmitted reliably, and furthermore, the directionality of pachinko balls is likely to be distorted.

(Means for Solving the Problems) The present invention was developed in view of the above circumstances, and involves passing pachinko balls between rotating bodies arranged opposite to each other, and using the rotational force of the rotating bodies to drive the pachinko balls. A ball launcher configured to launch a ball,
To provide a ball firing device for a pachinko machine, characterized in that a holding groove for holding pachinko balls through two or three points of contact with the balls is provided on the outer periphery of at least one of the rotating bodies.

(Function of the device) In this way, in the present invention, when applying a ball launching force to a pachinko ball, the guide rail and the pachinko ball do not come into contact, and the pachinko ball is passed between a pair of rotating bodies. This eliminates wear on the guide rail, and further reduces wear on the rotor itself due to the rotation of the rotor.

Furthermore, in this invention, the pachinko ball can be held in a stable state by the holding groove that holds the pachinko ball through two or three points of contact with the pachinko ball provided on the outer periphery of the rotating body. It is possible to reliably transmit the rotational force of the body to the pachinko balls and also to improve the direction of the pachinko balls.

(Example) Hereinafter, an example will be described with reference to the drawings. However, unless there is a specific description, the sizes and arrangement of the components described in this example are not intended to limit the scope of this invention, but are merely illustrative examples. Only.

1 and 2 show an embodiment of the present invention.

As shown in FIG. 1, a guide rail 4 for guiding pachinko balls to the game surface of the game board 1 is provided on the front surface of the game board 1 of the pachinko machine. At the base end of the guide rail 4, there is a main rotating body 5a and a sub rotating body 5 above and below.
A is provided. The sub rotating body 5b is the main rotating body 5
A is installed with an interval that allows pachinko balls to pass through. The main rotating body 5a is driven by a motor 2 provided on the back of the game board 1.

In this embodiment, on the outer periphery of the sub rotating body 5b,
A V-shaped retaining groove 3 is provided. As shown in FIG. 2, a bearing 12 is fitted into the rotating shaft 11 of the sub-rotating body 5b.
2 is held by a spring 13 so as to be movable up and down. Further, when the pachinko ball P passes between the main rotating body 5a and the sub rotating body 5b, the pachinko ball P is adjusted so that pressure is always applied to the pachinko ball P. In this way, the pachinko ball P is
By providing the retaining groove 3 in b, the main rotary body 5 is held in a stable state through contact at three points above and below.
The rotational force of a is reliably transmitted to the pachinko balls P, and the directionality of the firing of the pachinko balls P can also be improved. In addition, pachinko balls P with different diameters can be adjusted by vertically moving the auxiliary rotary body 5b, which can move up and down, and the pachinko ball P is arranged between the main rotary body 5a and the auxiliary rotary body 5b. The configuration is such that the spacing can accommodate differences in the diameters of the balls P.

3 and 4 show another embodiment of the present invention. In this embodiment, an elastic body 6 having elasticity such as rubber is attached to the outer periphery of the main rotating body 5a.
has been established. Therefore, when the diameter of the pachinko ball P is small, the pachinko ball P contacts the outer part of the elastic body 6, and when the diameter of the pachinko ball P is large, as shown by the dashed line in FIG. The body 6 is configured to be able to come into contact with the pachinko ball P in a compressed state. As a result, there is provided an interval between the main rotating body 5a and the sub rotating body 5b that can accommodate the difference in diameter of the pachinko balls P.

FIGS. 5, 6 and 7 show further embodiments of the present invention. In the case of this embodiment, the sub rotating body 5b is divided into two parts, and a spring 7 such as a coil spring is interposed in the center part. As a result, when the diameter of the pachinko ball P is large, the divided sub rotating bodies 5b mutually spread outward as shown in FIG. 6, and the pachinko ball P is placed between the main rotating body 5a and the sub rotating body 5b. When the diameter of the pachinko ball P is small, the force of the spring 7 to return to its original state causes the divided sub-rotating bodies 5b to approach each other, thereby separating the main rotating body 5a and the sub-rotating body 5b. The pachinko ball P can be kept in contact with the main rotating body 5a and the auxiliary rotating body 5b by narrowing the distance between them. In addition, in the embodiment, the sub rotating body 5b
The rotating shaft 8 may be provided with a spring that presses the divided sub rotating bodies 5b inward from both sides.

FIGS. 8 and 9 show still another embodiment of the present invention, and in this embodiment, the depth of the holding groove 3 of the sub-rotating body 5b is adjusted as shown in FIG. This is a difference. As a result, when the diameter of the pachinko ball P is large, the pachinko ball P can pass through a relatively deep part of the holding groove 3, whereas when the diameter of the pachinko ball P is small, the pachinko ball P can pass through a relatively shallow part of the holding groove 3. The pachinko ball P can be passed through. Furthermore, the holding groove 3 allows the pachinko ball P to be stably held by contact between the main rotating body 5a and the sub rotating body 5b at three or more points. In addition, when the structure of the holding groove 3 as shown in FIG. 9 is adopted in the above embodiment, the sub rotating body 5b is rotated in the direction shown by the arrow 9 in the figure. Further, in this embodiment, the motor 2 is provided on the sub rotating body 5b. In addition to this embodiment, the motor 2 may be provided on both the main rotating body 5a and the auxiliary rotating body 5b.

FIG. 10 shows yet another embodiment of the present invention, in which the sub rotating body 5b
is composed of a combination of members made of different materials with elastic bodies 6 disposed on both sides, and has a retaining groove 3 in the center.

FIG. 11 shows the holding groove 3 provided in the sub rotating body 5b.
Of these, only the part that contacts the pachinko ball P is the sub rotating body 5.
It is constructed of a member 10 made of a material different from the material constituting b. For the sub rotating body 5b shown in FIG. 11, by adopting the structure of the main rotating body 5a as shown in FIG. 2, it is possible to use ceramics or the like having excellent wear resistance for the member 10.

In the present invention, the holding groove 3 may be provided not only on the sub-rotating body 5b, but also on both the main rotating body 5a and the sub-rotating body 5b, or may be provided only on the main rotating body 5a. It may be. Further, the shape of the holding groove 3 is not limited to the V-shape, but may be any groove that can make contact with the pachinko ball P at two or three points, such as a polygon.

Furthermore, in the embodiment, the main rotating body 5a and the sub rotating body 5b
Although these are installed vertically, in the present invention, they may be installed horizontally. Further, although only the main rotating body 5a is driven by the motor 2, in the present invention, both the main rotating body 5a and the sub rotating body 5b may be configured to be driven by the motor 2. In this case, if the rotation of the pachinko ball P can be controlled by applying spin to the ball P based on the difference in the drive of the rotary bodies by the two motors 2, the pachinko game can be made even more interesting.

(Effects of the invention) As described above, according to the ball firing device according to the invention, since the pachinko balls are sandwiched between a pair of rotating bodies and fired by the rotational force of the rotating bodies, there is no wear on the guide rail. Not only can it withstand long-term use without damage, but it also has a holding groove that holds the pachinko balls through two or three points of contact with the pachinko balls provided on the outer periphery of the rotating body. It can be held in a stable state, the rotational force of the rotating body can be reliably transmitted to the pachinko balls, and the directionality of the pachinko balls can be improved.

In addition, in all of the embodiments, by changing the distance between the rotating bodies, it is possible to correspond to the difference in the diameter of the pachinko balls.
