Description

[Detailed description of the invention] (Field of industrial application) The present invention relates to a pachinko machine, and in particular, the invention does not use the conventional method of firing pachinko balls using a striking lever, but uses the rotational force of a rotating body to fire pachinko balls. This invention relates to a pachinko machine equipped with a ball firing device.

The gist of the present invention is to construct a firing section for a pachinko machine that is less likely to be worn out or damaged by pachinko balls even after long-term use, and to provide directionality to the ball ejection to ensure that the ball hits the pachinko board surface. In order to be able to guide the ball, there is a main rotating body that is driven to rotate,
A firing section consists of a sub-rotating body that rotates independently or in conjunction with the main rotating body and is arranged opposite to the main rotating body, and the firing section has an opening at one end to guide pachinko balls fired from the firing section in a predetermined direction. The guide tube is fixed such that the opening at the other end faces above the game board surface.

(Prior Art) Pachinko balls are usually launched using a hitting lever, but in order to shoot a pachinko ball accurately, the tip of the hitting lever and the center of the pachinko ball must be aligned correctly. No. 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 pachinko machine equipped with a ball firing device using a rotating body has been proposed, and an example of this is the one seen in Utility Model Application Publication No. 102085 of 1981. The ball firing device of this pachinko machine has a rotating body made of an elastic material arranged at a predetermined interval above the firing part of the guide rail,
This rotating body is rotated by a drive motor.

(Problem to be solved by the invention) According to this ball launcher, the pachinko balls are sandwiched between the base end of the guide rail, which is the launcher, and the rotating body, and are then guided by the rotational force of the rotating body. Fired along the rail. Therefore, the rotating body frequently applies strong pressure to the pachinko balls against the base end of the guide rail, which causes the base end of the guide rail to wear out or be damaged within a short period of time, causing the The guide rail had to be replaced.

Moreover, in the case of the conventional ball firing device, the rotational force of the rotating body is instantaneously applied to the pachinko ball to fire the pachinko ball, so it is difficult to guide the pachinko ball fired from the firing part to the game board surface. When a guide rail is used, there are cases where the pachinko balls fly upwards of the guide rail, making it difficult to give the fired pachinko balls directionality and reliably guide them to the game board surface.

The present invention was developed in view of these circumstances, and it constitutes a firing unit that is less likely to be worn out or damaged by pachinko balls even after long-term use, and also provides directionality to the firing of pachinko balls to ensure reliable firing. To provide a pachinko machine equipped with a ball firing device capable of guiding pachinko balls fired to a game board surface.

(Means for Solving the Problems) In order to solve the above-mentioned problems, the means adopted by the present invention are: a main rotating body that is rotationally driven; and a main rotating body that rotates independently or in conjunction with the main rotating body and is arranged opposite and a guide fixed such that one end opening faces the firing part and the other end opening faces above the game board surface in order to guide the pachinko balls fired from the firing part in a predetermined direction. It is characterized by having a tube.

(Effects of the device) Adopting this method has the following effects.
As the main rotating body rotates, pachinko balls are supplied one after another, and the pachinko balls that enter between the main rotating body and the sub rotating body are sandwiched between the main rotating body and the sub rotating body, and simultaneously launched by the rotational force of the main rotating body. be done. The fired pachinko balls are reliably guided to the upper part of the game board through a guide cylinder fixed such that one end opening faces the firing section and the other end opening faces above the game board surface.

As mentioned above, in the ball launching device of this pachinko machine, the pachinko balls are sandwiched between the rotating main rotating body and the auxiliary rotating body and fired, so the main rotating There is little wear and tear on the body and the auxiliary rotating body, and since the pachinko balls are launched by the rotational force of the main rotating body, there is no impact when the balls are launched. Moreover, by providing a guide tube,
The directionality of the pachinko balls fired from the firing section is maintained and they are reliably guided to the game board surface.
