Description

[Detailed description of the invention] I...Field of industrial application The invention consists of, for example, a rotating disk that displays numbers from 0 to 9 and is rotated by an appropriate means, an air gun (or gas gun), and its bullets. Regarding the structure of the bullet with display cloth that is loaded and fired into the air gun in a lottery machine, when the bullet of the present invention is fired from a set distance toward a rotating disc in a lottery drawing, etc., it is possible that the bullet will be attached to the bullet after firing. Since the display cloth protrudes to the rear, the display cloth allows the position where the bullet hits the rotating disc to be clearly visible even from a remote location such as the audience seats. .

...Conventional Issues Conventionally, lottery machines used for lottery drawings, etc. mainly shoot arrows from a bow and arrow at a rotating disk displaying numbers 0 to 9 and read the numbers that the arrows hit. However, since handling the bow and arrow is troublesome and the equipment is relatively large and bulky, it has been a challenge to simplify the operation of the lottery machine and make it smaller and lighter. Instead, it has been considered to fire bullets with an air gun and read numbers on the hit location, but since the bullets are small, it is difficult to visually check the bullets that hit the rotating disk from a remote location such as the audience seats. There are drawbacks that make it difficult to use, and solutions to these problems have been desired.

...Structure of the present invention The present invention effectively solves the above-mentioned conventional problems.

(1) ...That is, to explain the structure of the present invention,
It is a bullet with display cloth used for air guns for lottery machines,
It is characterized by having a sharp warhead and a cavity with an opening at the rear end, and a display cloth folded and stored in the cavity, so that the display cloth inside the cavity flies out from the rear end opening when fired. It is something to do.

(2) ...Next, an example of the present invention will be explained.
For example, in a lottery machine consisting of a rotating disc displaying numbers 0 to 9, an air gun, and its bullets, a sharp cylindrical piece with a display cloth that is loaded and fired into an air gun (e.g., handgun type). Bullet A (hereinafter simply referred to as Bullet A)
The bullet head 1 is formed to have a sharp point so as to pierce the rotating disk, for example by having a needle 2 protrude, and a hollow portion 4 with an opening 3 at the rear end of the bullet excluding the bullet head 1 is formed.
The display cloth 5 is appropriately folded and stored in the cavity 4.

The display cloth 5 is, for example, formed by forming a piece of cloth (paper, plastic sheet, etc.) in a clear color such as red, blue, yellow, etc. into a circle, etc., and connecting the center and the string fixing plate 6 to a set length (for example, a hollow The string fixing plate 6 is inserted and fixed at the tip of the cavity 4, and a small weight 8 is fixed to a part of the display cloth 5, if necessary. This is what I did.

...Function (1) ...For example, attach the string 7 to the center of the display cloth 5 formed into a circular shape, tie the other end of the string 7 to the string fixing plate 6, and insert the plate 6 from the rear end opening 3 into the cavity 4. Push it all the way to the inner tip and secure it so it doesn't come off easily.

As a result, the string 7 of the display cloth 5 is connected to the hollow portion 4.
When it is stretched out inside, the entire body will protrude to the outside from the rear end opening 3.

(2) ...Then, before the launch, the above display cloth 5 and string 7
In the illustrated example, it is in the shape of a small cannonball with a length of about 90 mm and a diameter of about 12 mm. Bullet A is stored, transported, and loaded in this state.

(3) ...In order to conduct a lottery, bullet A is loaded into a special air gun and fired toward a rotating disk. The bullet is pulled out by the negative pressure generated at the rear of the bullet and flies out of the rear end opening 3.

In addition, if there is a possibility that the display cloth 5 will not fly out properly by using only the inertia of the display cloth and the negative pressure at the rear of the bullet, attach a weight 8 to the display cloth 5 to ensure certainty (using inertia). increase.

(4) ...The needle 2 of the bullet head 1 of the fired bullet A pierces the rotating disk. At this time, since the display cloth 5 protrudes from the rear of the bullet A, the hit position of the bullet A can be clearly visually confirmed even from a remote location such as the audience seats.

...Effect (1) ...As mentioned above, the display cloth A of the present invention has a bullet-like external appearance because the display cloth 5 is stored in the cavity 4 before being loaded into the air gun and fired. Therefore, the display cloth does not pose any problem during storage, transportation, and loading operations for firing, and has the advantage of being easy to handle.

(2) ...When fired, the display cloth 5 automatically pops out to the rear of the bullet, so the presence of the display cloth 5 makes it possible to determine the hit location of bullet A even from a remote location such as the audience seats.
It has excellent features that can be visually confirmed.

(3) ...Unlike conventional bow and arrow type guns, they can be made smaller and lighter (especially when an air gun is replaced with a handgun type), and they are also easier to operate.
