When was the writing pencil invented?

The ballpoint pen was born in 1944 when a Hungarian Ladislo Bíró decided to create a pen that used the same ink, after discovering that printing ink dries quickly and does not stain manuscript paper. However, this sticky ink cannot flow out of the normal nib. With the help of their brother George, who was a chemist, they devised a pen that used capillary action to send ink to the ballpoint.

In 1954, the Parker Pen Company introduced the premium JOTTER ballpoint pen, which was large and could be refilled when the ink ran out.

Ballpoint pens have the advantages of simple structure, easy to carry, smooth writing, and suitable for copying, so people from all walks of life from school students to office building clerical staff are happy to use it. The writing principle of the ballpoint pen is mainly to use the ball ball to produce friction in direct contact with the paper surface when writing, so that the ball rolls in the ball seat and brings out the ink or ink in the refill, so as to achieve the purpose of writing.

In 1888, four years after the invention of the fountain pen by Waltman, the American Raby proposed a new concept of pen, which is different from the fountain pen, but is equipped with a ball on the nib, and when writing, with the rolling of the ball, the ink is left on the paper, which is what people today call "ballpoint pen". Regrettably, Rabi's attempt failed, on the one hand, because the beads did not roll well and could not write; On the other hand, the ink flowing through the beads is uncontrollable and leaks a lot. The invention was delayed.

More than half a century later, in 1943, a proofreader named Laszro Josef Bick of a Hungarian printing house found that the freshly printed proofs on the machine contained a lot of water, and when corrected with a fountain pen, the phenomenon of wetting and blurring would occur. To this end, he often pondered how to improve it.

Once, Vic found a round tube, filled it with oily paint, and changed the nib to a steel ball, and the world's first ballpoint pen was born. Later, Vic made the invention available to the Royal Air Force. Soon, an aircraft factory in the United Kingdom launched the first commercial ballpoint pens.

At that time, a businessman named Reynolds in the United States saw this ballpoint pen, like a hound with a keen sense of smell discovering its prey, and with the unique sensitivity of the businessman, he decided that it was a new product with a promising future.

It was the end of World War II, and the atomic bomb was successfully built in the United States! In order to sensationalize and attract customers, Renault ingeniously called the ballpoint pens he produced and sold "ballpoint pens". Renault claims that his ballpoint pen can write underwater, can be used in the cold Arctic, can write for long periods of time, and is portable.

Amu Tong writes constantly pencil free to cut and free to press while writing while out of the core in 2011.

The pencil was invented by Joseph Hartmut. Hartmut was born on February 20, 1752, to a carpenter in Aspern, Lower Austria. Hartmut invented the pencil by adding a suitable scale of clay to the graphite powder to give the lead a certain hardness.

The invention of the pencil solves the problem of human writing, and with the progress of science and technology, the pencil is getting cheaper and cheaper, and has become an indispensable part of human stationery. Whether in teaching or scientific research, there are pencils.

The history of the pencil.

Wooden pole graphite pencil originated in England during the 16th century. However, the world's first pencil factory was built in the 17th century when the tomb was defeated by Germany. In the 18th century, the French began to study and reform the lead core, and they improved the process of making the lead of the pencil, and they succeeded.

Because of the improvement of the French, the use value of the pencil.

It has made a major breakthrough and promotion, and also laid the foundation for the development of the pencil industry and pointed out the direction.

The pencil was invented by the Austrian Joseph Hartmut. Pencil is mainly made of graphite as raw material, plus the pen barrel, thus forming a "pencil", although now the computer is widely used, but the pencil is still one of the indispensable stationery in the world, it is a necessary writing tool for people who have often worked outdoors, do not need to grind ink to write handwriting, to provide a lot of convenience for people.

Introduction to pencils. As early as the Middle Ages, people used lead and silver rods to write, and this tool was more about engraving than writing. By the 15th century, the first lead-tin refills were made in Italy.

The discovery of graphite in England in 1658 revolutionized writing tools, although the pen was very expensive at the time.

And the inventor of the pencil was Austrian Joseph Hartmut. His father was a carpenter from Aspern, Austria. So Hartmut learned the mason's trade in Vienna and later became an architect, setting up a brick factory.

At that time, the quality of the pen used for writing was poor, so he decided to invent a new pen.

Later he came up with an idea: to mix clay with graphite powder and make it into the shape of a refill, which was fired in a fire so that traces could be drawn on paper. He added the right proportion of clay to the graphite powder to give the pencil lead a certain hardness.

In 1792, he founded his own pencil factory in Vienna, which still produces pencils to this day.

1.The mechanical pencil was invented in 1919.

In the year, Syunichinakata, a collector of imported pens, opened a small pen store in Okayama, Japan, and his store became a success.

In the year he moved to Tokyo, where he officially named his company Nakayaseisakusho near several pen manufacturers.

4.After that, the company exceeded imagination and grew rapidly, with 80 employees, Yu Tsai Pai is Nakata changed the name of the company"platinumpencompany", which is the famous platinum medal.
