Description

[Detailed description of the invention] (Field of industrial application) The present invention relates to a ball launcher for a pachinko machine, which uses the rotational force of a rotating body to hit the ball instead of the conventional hitting lever. It is a type that shoots pachinko balls, and in detail, it corresponds to the size of the diameter of the pachinko balls, and even if the diameter of the pachinko balls varies, it ensures that the same rotational force is applied to each pachinko ball. The present invention relates to a ball launcher in which the shape of the outer periphery of at least one of the rotating bodies is tapered so as to increase the force of the ball.

(Prior art) Pachinko balls are normally launched using a striking lever, but in order to accurately launch a pachinko ball, the tip of the striking lever and the center of the pachinko ball must be aligned correctly. . In order to do this, a fairly sophisticated technique is required to adjust the position, and there is a problem in that it takes time to assemble the pachinko machine. In addition, the impact noise generated when pachinko balls are hit has also been a problem.

In order to solve this problem, a ball launcher using a rotating body was proposed.
There is something like the one seen in 2009 Utility Model Application Publication No. 102085. This batted ball firing device has a rotating body made of an elastic material arranged and installed at a predetermined interval above a firing section of a guide rail, and this rotating body is rotated by a drive motor.

According to this ball launcher, the pachinko balls are held between the base end of the guide rail and the rotating body, and are then launched along the guide rail by the rotational force of the rotating body. Therefore, the pachinko balls are frequently pressed strongly against the base end of the guide rail by the rotating body, which causes the base end of the guide rail to wear out or be damaged within a short period of time, and the guide The rails will have to be replaced. In addition, according to this ball launcher, the distance between the base end of the guide rail where the pachinko balls are sandwiched and the rotating body is constant, and it is possible to apply an equal rotational force to each pachinko ball, which has a different diameter. is not possible. For example, if the distance between the base end of the guide rail and the rotating body is set to match a pachinko ball with a relatively large diameter, the rotational force of the rotating body will not be applied sufficiently to a pachinko ball whose diameter is smaller than that distance.
If the distance between the base end of the guide rail and the rotating body is adjusted to a relatively small pachinko ball, it will not be possible to shoot a pachinko ball with a diameter larger than the distance, which may cause a malfunction.

(Problems to be Solved by the Invention) The present invention was created in view of the above-mentioned problems, and the problems to be solved are as follows:
To provide a ball launcher with a simple configuration that does not cause wear or damage to the guide rail even after long-term use and can apply an equal rotational force to each pachinko ball of varying diameter. It is about providing.

(Means for Solving the Problems) The means adopted by the present invention to solve the above problems is to pass pachinko balls between rotating bodies arranged facing each other, and to use the rotational force of the rotating bodies to A ball launching device for firing pachinko balls, characterized in that the outer periphery of at least one of the rotating bodies is tapered so that the spacing between the rotating bodies is not parallel to the pachinko balls. This is a ball launcher in an aircraft. In other words, the ball launcher according to the present invention is configured such that a pachinko ball is sandwiched between a pair of rotating bodies and is launched toward a guide rail by the rotational force of the rotating bodies.
In addition, the shape of the outer periphery of at least one of the rotating bodies is tapered, so that even if the diameter of the pachinko balls varies, the pachinko balls are held at intervals that match the diameter of the pachinko balls, and one pachinko ball can be held. An equal rotational force is applied to each.

(Embodiment) An embodiment of the ball launcher according to the present invention will be described below with reference to the drawings. However, the materials, dimensions, etc. of the components described in the examples are merely illustrative examples and are not intended to limit the scope of this invention, unless otherwise specified.

As shown in FIG. 1, the ball launcher according to the present invention includes a main rotating body 20 with a tapered outer periphery and a sub rotating body 30 with a tapered outer periphery in the vicinity of the guide rail 11. It is constructed by arranging. The shape of the outer periphery of the main rotor 20 and the sub-rotator 30 can be ensured by changing the position in which each of the pachinko balls B, which vary in diameter, makes contact with the main rotor 20 and the sub-rotator 30. It is tapered so that an equal rotational force is applied to pachinko balls B having different pinch diameters. The guide rail 11, the main rotating body 20, and the sub rotating body 30 are attached to a board 12, and this board 12 is fixed to the lower part of the game board surface of the pachinko machine. The guide rail 11 guides the launched ball to the upper part of the game board surface, and has an opening 11a at a part of its base end.
is formed. An introduction plate 13 for introducing balls intermittently supplied from a pachinko ball supply device (not shown) between the main rotating body 20 and the sub rotating body 30 is fixed to the rear part of the opening 11a. A holding plate 14 made of a plate-shaped elastic material is fixed to press the pachinko ball B against the rotating bodies 20 and 30 so that the rotational force of the main rotating body 20 and the auxiliary rotating body 30 is applied to the ball B reliably. That is, the presser plate 14
When the pachinko balls B having different diameters pass between the main rotating body 20 and the auxiliary rotating body 30, a biasing force is applied to ensure that the pachinko balls B always come into contact with the main rotating body 20 and the auxiliary rotating body 30. It is made up of an elastic body with

The main rotating body 20 is placed above the opening 11a at a distance approximately equal to the diameter of the pachinko ball B, and
It is driven by a drive motor 22 attached to the back surface of the substrate 12 and rotates in the direction of the arrow in the figure. Further, a rubber band 21 is wound and fixed around the outer periphery of the main rotating body 20, so that the main rotating body 20 has elasticity with respect to the pachinko balls B. Incidentally, the outer periphery of the rubber band 21 is provided with serrations 21a.

A sub rotating body 30 is arranged below the main rotating body 20, and the upper end of this sub rotating body 30 is connected to the guide rail 1.
It protrudes slightly upward from the opening 11a of No. 1.
Further, a rubber band 31 is wound and fixed around the outer periphery of the auxiliary rotating body 30, so that the auxiliary rotating body 30 has elasticity with respect to the pachinko balls B. Note that serrations 3 are provided on the outer periphery of the rubber band 31.
1a has been applied.

Furthermore, in this embodiment, by rotating the handle H, the drive motor 22 of the main rotating body 20 is first driven, and the pachinko ball B is moved to the introduction plate by the pachinko ball supply device (not shown). It is designed to be intermittently supplied from above 13.

Next, the operation of the ball launcher according to the present invention configured as described above will be explained. By operating the handle H, the main rotating body 20 rotates, and pachinko balls B are supplied from above the introduction plate 13. This pachinko ball B enters between the main rotor 20 and the sub-rotator 30 along the introduction plate 13, and is pressed in the direction of the board 12 by the presser plate 14. At the same time as it is pinched, it is fired by the rotational force of the main rotating body 20. At this time, the pachinko ball B, which has a relatively small diameter, is sandwiched between the main rotating body 20 and the sub rotating body 30 at a position closer to the base plate 12, and rotational force is reliably applied thereto.
Moreover, the pachinko ball B with a relatively large diameter is
It is sandwiched between the main rotating body 20 and the auxiliary rotating body 30 at the position of twist 4, and rotational force is reliably applied. In addition, when pachinko ball B is sandwiched between two rotating bodies 20 and 30 and fired at the same time, the number of points in contact with pachinko ball B is reduced to 3 due to the provision of presser plate 14, and the number of contact points of pachinko ball B after firing is reduced to 3. Improves direction. The fired pachinko ball B is guided to the game board surface by the guide rail 11. In the ball launcher of the present invention,
Since the pachinko ball B is fired by being sandwiched between the main rotating body 20 and the sub rotating body 30,
Since the pachinko ball B is not strongly pressed against the guide rail 11, there is no wear or damage to the guide rail 11, which has been a problem in the past.
In addition, in the case of this embodiment, the pachinko ball B is not hit by a hitting lever as in the conventional case, but is hit by a main rotating body 20 having a rubber band 21 and a sub rotating body 30 having a rubber band 31. Since it is held in place and sent out by the rotational force of the main rotating body 20, the noise that would be generated by a blow is not generated, and the impact is not transmitted to the hand holding the handle H. Not at all. Furthermore, the ball launcher of the pachinko machine can be disposed not only at the launcher (base end) of the guide rail 11, but also above it, so that the ball launcher can be placed above the guide rail 11.
can be omitted. Therefore, the pachinko machine itself can be made compact, and space can be secured to accommodate other equipment as needed.

In this embodiment, the outer peripheries of the main rotating body 20 and the sub rotating body 30 are tapered, but in the present invention, the outer periphery of only one of them may be tapered. Furthermore, in the present invention, the mounting orientation of the main rotating body 20 and the sub rotating body 30 is not limited only to this embodiment.
As shown in the figure, the main rotating body 20 and the sub rotating body 30 may be installed in opposite directions. At this time, spring 1
5 and a cap 16 is attached to the base 12 side. In addition, although the description has been given of a device that allows the sub-rotating body 30 to rotate freely, that is, one that rotates following the main rotating body 20 when the pachinko ball B arrives, the sub-rotating body 30 can be driven by a gear mechanism or the like. Alternatively, the driving force of the drive motor of the main rotating body 20 may be used. Further, the sub rotating body 30 may be rotated independently of the main rotating body 20 by another drive motor. In this case, if the rotational speed of the main rotating body 20 or the secondary rotating body 30 can be freely changed relative to the rotational speed of the other, rotational force can be applied to the fired pachinko ball B, resulting in so-called positive spin. Alternatively, it is possible to shoot the pachinko ball B with a reverse spin or with no spin applied, which can bring about a great change in the pachinko game. Further, in the above example, a case has been described in which the rubber band 21 and the rubber band 31 are respectively fixed to the main rotating body 20 and the sub rotating body 30, but this is not particularly necessary in the present invention.

(Effects of the invention) As detailed above, according to the ball launcher according to the invention, there is no wear or damage to the guide rail even after long-term use, and pachinko balls with varying diameters can be used. It is possible to provide a ball launcher with a simple configuration that can reliably apply an equal rotational force to each ball.
