ものである。BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an angle ruler composed of a frame portion having ruled lines and angle scales and a circular rotary ruler portion used for drawing two straight lines intersecting at an arbitrary angle.

引いていた。2. Description of the Related Art Conventionally, when drawing two straight lines intersecting at an arbitrary angle, a straight line ruler is first used to draw a straight line, and then a point (intersection point) on the straight line is drawn, except that a drafting device such as a drafter is used. Take an arbitrary angle (point) with a protractor around
A straight line was drawn between that point and the point on the straight line (intersection point).

規でむすび直線を引く時にも誤差が生じやすい。When drawing two straight lines intersecting at an arbitrary angle, a drawing tool such as a drafter can be used for accurate drawing, but the tool is too large to be used on a desk in a small space. In addition, when drawing two straight lines that intersect at an arbitrary angle easily on a desk, etc., a straight line ruler and a protractor are always required, and errors are likely to occur when taking an angle (point) with a protractor. A line ruler is used to draw points on a straight line (intersection points).
【０００４】本発明は、小さなスペースの机の上等でも
簡単に、任意の角度で交差する二直線を正確に描くため
の角度定規である。The present invention is an angle ruler for accurately drawing two straight lines intersecting at an arbitrary angle even on a desk or the like in a small space.

規部分２とを組み合わせたものである。The present invention has been devised in order to eliminate the above-mentioned drawbacks. Referring to the drawings, a frame portion 1 having ruled lines 5 and angle scales 3 and a circular rotary ruler portion 2 are provided. It is a combination.

盛り３の任意の角度に合わせ、直線を引けばよい。Function: The ruler portion of the rotary ruler portion 2 is aligned with 0 ° and 180 ° of the angle scale 3 of the frame portion 1, and a straight line is drawn. Next, the ruler portion of the rotary ruler portion 2 may be rotated to match an arbitrary angle on the angle scale 3 of the frame portion 1 and a straight line may be drawn.

等のように簡単に使用でき、持ち運びも簡単である。As described above, when two straight lines intersecting at an arbitrary angle are drawn, an error hardly occurs because the straight line can be drawn by simply adjusting the angles. Furthermore, like the conventional protractor, the angle formed by two intersecting straight lines can be easily measured. In addition, it can be easily used like a template on a desk in a small space and is easy to carry.
