일반적으로, 자와 컴퍼스, 각도기를 모두 사용하기 위해서는 가방이나 큰 필통에 세 개의 학용품을 모두 휴대해야 했고, 이 세 개의 학용품을 통해서는 오직 그림만을 그릴 수 있었다.Generally, in order to use all the rulers, compasses, and protractors, you had to carry all three school supplies in your bag or large pencil case, and you could only draw with these three school supplies.

그러나, 각기 모양이 달라서 휴대 공간이 커야 하는 불편함이 있다.However, each of them has a different shape, so there is an inconvenience that the carrying space must be large.

또한, 세 개의 학용품을 통해 지식을 습득할 수 있는 부분이 없다는 단점이 있다.In addition, there is a disadvantage that there is no part where knowledge can be acquired through the three school supplies.

본 발명이 해결하고자 하는 과제는 휴대의 불편함을 개선 시킬 수 있는 컴퍼스와 각도기의 기능이 담긴 자를 제공하는 것이다.The problem to be solved by the present invention is to provide a ruler containing the functions of a compass and a protractor that can improve the inconvenience of carrying.

본 발명이 해결하고자 하는 과제는 컴퍼스, 각도기, 자를 통해서 지식을 습득할 수 있는 컴퍼스와 각도기의 기능이 담긴 자를 제공하는 것이다.An object to be solved by the present invention is to provide a compass and a ruler having functions of a protractor that can acquire knowledge through a compass, a protractor, and a ruler.

본 발명은 앞서 본 목적을 달성하기 위하여 다음과 같은 구성을 가진다.The present invention has the following configuration in order to achieve the above object.

본 발명의 컴퍼스와 각도기의 기능이 담긴 자는, 길이를 잴 수 있는 자 눈금;Ruler containing the function of the compass and protractor of the present invention, a ruler that can measure the length;

컴퍼스의 기능을 할 수 있는 컴퍼스 구멍; 각도기의 기능을 할 수 있는 각도기 구멍;을 포함한다.a compass hole that can function as a compass; It includes; a protractor hole that can function as a protractor.

본 발명은 컴퍼스, 각도기, 자 이렇게 세 개의 학용품을 휴대하는데에 있어서 좀 더 용이하다는 효과가 있다.The present invention has the effect of making it easier to carry three school supplies such as a compass, a protractor, and a ruler.

본 발명은 컴퍼스와 각도기의 기능이 담긴 자를 통해 지식을 습득할 수 있는 효과가 있다.The present invention has the effect of acquiring knowledge through a ruler containing the functions of a compass and a protractor.

도1은 본 발명의 바람직한 실시예에 따른 컴퍼스와 각도기의 기능이 담긴 자를 설명하기 위해 나타낸 전체도.1 is an overall view illustrating a ruler containing functions of a compass and a protractor according to a preferred embodiment of the present invention.

이하, 첨부된 도면을 참조하여 본 발명의 바람직한 실시예를 상세하게 설명한다. 도 1을 참조하면, 자 눈금(10)은 0cm부터 15cm까지 측정할 수 있게 보통 자와 같이 본 발명품의 몸체의 상부에 위치한다. 자 눈금(10)의 사용 방법은 보통 자와 같이 길이를 재고, 원하는 길이의 선분을 그릴 수 있다. 컴퍼스 구멍(20)은 본 발명품의 몸체의 하단에 위치하고, 구멍은 총 15개로, 구멍 간 간격은 모두 1cm이다. 각도기 구멍(30)은 본 발명품의 중심, 자 눈금(10)과 컴퍼스 구멍(20)의 사이에 위치하고, 15° 30° 45° 60° 75°를 표현할 수 있는 구멍 5개가 각각 좌우로 대칭적으로 있다.Hereinafter, preferred embodiments of the present invention will be described in detail with reference to the accompanying drawings. Referring to FIG. 1, the ruler scale 10 is located on the upper part of the body of the present invention like a regular ruler so that it can measure from 0 cm to 15 cm. The method of using the ruler scale 10 can measure the length like a regular ruler and draw a line segment of a desired length. The compass hole 20 is located at the lower end of the body of the present invention, there are 15 holes in total, and the distance between the holes is all 1 cm. The protractor hole 30 is located in the center of the present invention, between the ruler scale 10 and the compass hole 20, and five holes capable of expressing 15 ° 30 ° 45 ° 60 ° 75 ° are symmetrically left and right, respectively. there is.

컴퍼스 구멍(20)과 각도기 구멍(30)의 사용 방법을 설명하기 위해 컴퍼스 구멍(20)의 가운데 구멍을 중심으로 각 구멍에 0, 1, 2, 3, 4, 5, 6, 7의 이름을 대칭적으로 붙여주고, 각도기 구멍(30)의 맨 위의 구멍부터 75° 60° 45° 30° 15°의 이름을 대칭적으로 붙여준다. 컴퍼스 구멍(20)의 사용 방법은 임의로 구멍을 선택해서, 연필을 끼워 컴퍼스의 축을 고정하고, 원하는 반지름의 길이가 있다면 그 길이에 맞게 다른 한 구멍을 찾아 다른 연필을 끼워 축으로 고정한 연필을 축으로 하여 다른 연필을 돌리게 되면 원하는 반지름 길이의 원이 나온다. 예를 들어, 반지름의 길이가 5cm인 원을 그리고 싶다면 구멍 0에 연필을 꽂아 축의 역할을 하고, 구멍5에 연필을 꽂으면, 구멍0에 꽂은 연필을 축으로 하고, 구멍5에 꽂은 연필을 돌리게 되면 반지름의 길이가 5cm인 원을 그릴 수 있다. 각도기 구멍(30)의 사용 방법은 먼저 구멍 0에 연필로 점을 찍고, 구멍1에 연필로 점을 찍고, 원하는 각도가 있다면 그 각도에 해당하는 구멍에 연필로 점을 찍는다. 처음 구멍0에 찍은 점을 각의 꼭짓점으로 하고, 구멍0과 구멍1을 잇고, 구멍0과 원하는 각을 위한 각도기 구멍(30)을 이어주면 원하는 각을 그릴 수 있다. 예를 들어, 45°의 각을 그리기 위해 구멍0에 연필로 점을 찍고, 구멍1에 연필로 점을 찍고, 구멍45°에 연필로 점을 찍어서 구멍0 위치에 찍힌 점과 구멍1 위치에 찍힌 점을 잇고, 구멍0 위치에 찍힌 점과 구멍45° 위치에 찍힌 점을 이어서 45°의 각을 그릴 수 있다. 본 발명품을 사용하면서 삼각비, 피타고라스 정리, 내분과 외분 등의 수학적 지식을 본 발명품의 컴퍼스 기능과 각도기 기능을 활용하면서 습득하고, 습득한 지식을 활용해 볼 수 있다.In order to explain how to use the compass hole 20 and the protractor hole 30, the names 0, 1, 2, 3, 4, 5, 6, and 7 are given to each hole centered on the center hole of the compass hole 20. Attach them symmetrically, and attach names 75° 60° 45° 30° 15° symmetrically from the top hole of the protractor hole 30. The method of using the compass hole 20 is to select a hole at random, insert a pencil to fix the axis of the compass, and if there is a length of the desired radius, find another hole to match the length and insert another pencil into the axis to fix the pencil as an axis. If you turn the other pencil, a circle with the desired radius comes out. For example, if you want to draw a circle with a radius of 5 cm, insert a pencil into hole 0 to act as an axis, and insert a pencil into hole 5. Then you can draw a circle with a radius of 5 cm. The method of using the protractor hole 30 is to first put a dot on hole 0 with a pencil, put a dot on hole 1 with a pencil, and if there is a desired angle, put a dot on the hole corresponding to the angle with a pencil. The desired angle can be drawn by making the point taken at hole 0 first as the vertex of the angle, connecting hole 0 and hole 1, and connecting hole 0 and the protractor hole 30 for the desired angle. For example, to draw an angle of 45°, put a pencil dot at hole 0, a pencil dot at hole 1, a pencil dot at hole 45°, and a dot at hole 0 and a dot at hole 1. By connecting the dots, you can draw an angle of 45° by connecting the dot at hole 0 and the dot at hole 45°. While using the present invention, mathematical knowledge such as trigonometric ratio, Pythagorean theorem, inward and outward division, etc. can be acquired while utilizing the compass function and protractor function of the present invention, and the acquired knowledge can be utilized.

본 발명은 상술한 실시예에 한정되지 않으며, 첨부된 청구범위에서 알 수 있는 바와 같이 본 발명이 속한 분야의 통상의 지식을 가진 자에 의해 변형이 가능하고 이러한 변형은 본 발명의 범위에 속한다.The present invention is not limited to the above-described embodiments, and as can be seen from the appended claims, modifications can be made by those skilled in the art to which the present invention belongs, and such modifications fall within the scope of the present invention.
