Description

[Detailed Description of the Invention] (Industrial Application Field) The present invention relates to a ball launching device for a pachinko machine that uses a rotating body installed on a guide rail to launch pachinko balls.

(Prior art) Conventionally, ball launchers using a rotating body include:
This is described in Japanese 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.

(Problems to be Solved by the Invention) However, in the case of such a configuration, there was a problem that it could not cope with the diameter of the pachinko ball, and the ball launch became unstable. That is, according to the conventional configuration, the interval between the rails guiding the rotating body is always maintained constant. However, the surface of pachinko balls wears out due to frequency of use. In particular, pachinko balls are regularly polished by rubbing a large number of balls against each other to prevent rust from forming on the surface, so there is a difference in diameter between new and well-used balls. In the case of conventional ball launchers, these differences in the diameter of pachinko balls are not taken into account, so the contact between the pachinko balls and the rotating body is unstable, and as a result, the rotating body The ball launch force applied to the ball cannot be kept constant either. This results in the inconvenience that the flight distances of the pachinko balls launched onto the game surface of the game board vary.

The present invention was made in view of these circumstances, and is a ball launcher equipped with a rotating body.
It is an object of the present invention to provide a ball firing device for a pachinko machine that can reliably apply a constant ball firing force to pachinko balls in response to the difference in diameter of the pachinko balls.

(Means for solving the problem) That is, the ball launcher according to the present invention is arranged so as to face each other on the guide rails for guiding pachinko balls to the game surface of the game board, and Therefore, it is equipped with a main rotating body and a secondary rotating body that fire pachinko balls, and at least one of the rotating bodies has a trajectory that oscillates due to its rotation, and the difference in diameter of the pachinko ball is determined by the amplitude width of the trajectory. It is characterized by the fact that it is formed by a rotating body that absorbs water and makes pachinko balls of the same diameter contact each other on an orbit with a fixed amplitude.

(Function of the invention) As described above, the ball firing device according to the invention absorbs and corresponds to the difference in the diameter of the pachinko ball by the amplitude width of the rotating body having a trajectory that oscillates due to rotation. It is now possible to reliably capture pachinko balls and launch them toward the guide rail. In other words, if the pachinko ball has a small diameter, it will come into contact with the outer surface of the rotating body at the large radius part, and if the pachinko ball has a large diameter, it will come into contact with the outer surface of the rotating body at the small radius part. By doing so, it is now possible to match the diameter of the pachinko ball. It is now possible to reliably apply a certain ball launching force to these 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.

FIG. 1 shows an embodiment of the present invention,
A guide rail 4 for guiding pachinko balls to the game surface of the game board 2 is provided on the front surface of the game board 2 of the pachinko machine. At the base end of the guide rail 4, a main rotating body 5a and a sub rotating body 5a are provided above and below. The main rotating body 5a is driven by a motor 6 provided on the back of the game board 2. The sub rotating body 5b is provided to face the main rotating body 5b, and is spaced apart from the main rotating body 5a so that pachinko balls can pass therethrough. In the case of this embodiment, the outer shape of the main rotating body 5a is formed into an ellipse, and when the main rotating body 5a is rotated, an inner circle formed by the short axis of the ellipse and the long axis of the ellipse form an inner circle. A trajectory is formed that oscillates between the outer circle and the outer circle. The amplitude width of this rotating body allows it to absorb and correspond to the diameter of the pachinko ball P.

Therefore, when pachinko balls P with different diameters pass between the main rotating body 5a and the auxiliary rotating body 5b, a certain amount of force is applied to each pachinko ball as shown in FIGS. 2 and 3. It is now possible to reliably impart ball launch force. That is, when the diameter of the pachinko ball P is small, as shown in FIG. The rotational force of is transmitted to the pachinko ball P to cause the pachinko ball P to be launched. On the other hand, when the diameter of the pachinko ball P is large, as shown in FIG. The rotational force of the pachinko ball P is transmitted to the pachinko ball P.
to fire. In order to launch this pachinko ball P, there is no need to control the rotational drive of the main rotating body 5a. This is because if the main rotating body 5a is always in a rotating state, the amplitude of the orbit will always change,
A pachinko ball P that passes between the main rotating body 5a and the sub rotating body 5b will reach the main rotating body 5 at any amplitude.
This is because the rotational force is reliably applied to the contact point a. In this embodiment, the pachinko ball P passing between the main rotor 5a and the sub-rotator 5b is reliably captured while the main rotor 5a makes half a rotation. Therefore, pachinko balls P with different diameters
Even if the pachinko balls P are continuously sent out, by simply keeping the main rotating body 5a constantly rotating, the pachinko balls P will be launched one after another through the guide rail 4 and onto the game surface 3 of the game board 2. There is. In addition, ball launching force is reliably imparted to the pachinko ball.

The difference in the diameter of the ellipse of the main rotating body 5a only needs to correspond to the diameter of the pachinko ball P, and may be larger than that. Also,
As shown in FIG. 4, the shape may be such that the large diameter portion is provided in only one direction.

5 and 6 show another embodiment of the present invention, in which the main rotating body 5a is formed in a perfect circle,
The shaft is not located at the center but at an eccentric position. The degree of eccentricity is such that the width of the amplitude of the orbit between the outer circle and the inner circle formed when the main rotating body 5a is rotated can absorb and correspond to the difference in the diameter of the pachinko ball. It is.
As a result, when the diameter of the pachinko ball P is small, as shown in FIG. The rotational force of 5a is transmitted to the pachinko ball P to fire the pachinko ball P. On the other hand, when the diameter of the pachinko ball P is large, as shown in FIG. The rotational force of is transmitted to the pachinko ball P, and the pachinko ball P is launched.

The outer surfaces of the main rotating body 5a and the sub rotating body 5b may be provided with an elastic body such as rubber, or may be made of a material having wear resistance such as ceramic.

In the embodiment, the main rotating body 5a and the sub rotating body 5b are installed vertically, but in the present invention, they may be installed horizontally. Further, only the main rotating body 5a is driven by the motor 6, but in the present invention, the main rotating body 5a,
Both of the sub-rotating bodies 5b may be configured to be driven by motors, and in this case, the rotation of the pachinko ball P can be controlled by applying spin to the pachinko ball P based on the difference in the rotational drive of the two motors. By doing so, you can make your pachinko game even more interesting.

(Effects of the invention) According to the ball firing device according to the invention, since the pachinko balls are sandwiched between a pair of rotating bodies and fired toward the guide rail by the rotational force of the rotating bodies, Not only can it withstand long-term use without wear or damage, but at least one of the main or sub-rotators has an orbit that vibrates due to its rotation, and the diameter of the pachinko balls can vary in size. is absorbed by the amplitude width of the trajectory, and pachinko balls of the same diameter are brought into contact with each other on a trajectory of a fixed amplitude. A constant rotational force of a rotating body can be reliably transmitted to a pachinko ball. Further, stable ball firing can be expected with such a ball firing device, and there is no problem of the pachinko balls flying at different distances as in the past.
