We all know that the invention of the copier has brought great convenience to our lives. Although China has long had a series of inventions such as movable type printing, the copier can make our books available very quickly. It can be printed out at a very fast speed and can be bound into books to spread knowledge to us, so its invention is very great and its impact on the world is also huge. So who invented the photocopier? The copier was created by Chester Carlson. The copier built by Carlson was also the first in the world. So what was the invention process of the copier? Next, the editor will tell you in detail.
Chester Carlson was originally a lawyer, not a professional inventor. He was just a part-time researcher and inventor. He worked in the New York Patent Office. This job required copying a large number of important documents, and Carson suffered from arthritis, so copying documents made him feel extremely painful. It was also for this reason that he was inspired to create a document that could be easily It was a quick and easy way to reproduce text, so Carlson experimented in his kitchen at home.
Then after repeated attempts, he used chips covered with sulfur to produce the first copying product. He applied for a patent for this process and technology. Carlson planned to sell his invention to some companies, but because the technology was not particularly mature or perfect, he failed to succeed and no company bought his technology. It wasn't until 1944 that a non-profit organization in Columbus, Ohio signed a contract with Carlson to perfect his invention. Over the next five years, they conducted many experiments and repeated attempts. Finally, this technology was successfully developed. and applied for a patent for the copier. Since then, copiers have been widely used in our lives.
We are also very grateful to Carlson for this great invention, because he has reduced us a lot of pressure in work and study.
