Abstract
Description
[Technical Field]
[0001] Of course, you can use a ruler to draw lines, but it is also the first in the world to be able to draw circles with a ruler, adding another item to the Japanese stationery that Japan is proud of around the world. [Background technology]
[0002] Anyone can easily draw a circle with a tape measure, even in the early grades. One stationery item used solely for drawing circles that shows no signs of improvement is the forked compass, used by children from early grades to adults. While precision drawings and compasses for nautical charts are an exception, it remains inconvenient for anyone to use when drawing a circle. The problem has been solved by using a tape measure instead of the traditional compass. DISCLOSURE OF THE INVENTION [Problem to be solved by the invention]
[0003] Academic tape measures 1cm to 2cm and have a round hole at the end for a pencil. Professional tape measures meters and has a scale with 0mm and 1cm printed on a 20cm long steel plate. The end of the scale has Velcro so that a pencil or magic marker can be wrapped around it. [Means for solving the problem]
[0004] The educational version is the ultimate scale compass that can be carried anywhere, conveniently in a pencil case, file folder, or breast pocket. The professional version comes with a belt and hook. [Effects of the Invention]
[0005] Everyone was delighted, especially the younger students. Conventional compasses are difficult to write with and tend to slip when used on a writing pad, making it difficult to write with. However, this major scale compass has been well received as it allows you to easily draw circles of any size you want, anywhere you like. BEST MODE FOR CARRYING OUT THE INVENTION
[0006] Conventional compasses have not shown any signs of improvement for decades or even centuries to come, but we are not criticizing compasses for drafting or nautical charts. Rather, we have arrived at a compass that can be used simply for learning and arts and crafts, allowing you to draw circles quickly, neatly, and easily, all with just a tape measure. [Example]
[0007] Now that we know that a single tape measure can replace a compass, we want to make it a better product that is safe and reliable so that even younger students can use it to study circles and pie charts quickly. [Industrial Applicability]
[0008] The measuring compass can be used in a wide range of industries, including the education industry and stationery-related industries, and will be a replacement for conventional compasses in the future, making it a useful tool for a wide range of business purposes.
