What is the patent for copier technology?

We all know that the invention of the copier has brought great convenience to our life. Although China had a series of inventions such as movable type printing a long time ago, the copier can print out our books at a fast speed and bind them to spread knowledge to us, so its invention is very great and has a great impact on the world. So who invented the copier? The copier was invented by Chester Carlson, and the copier made by Carlson is the first one in the world. So what was the process of the invention of the copier? Next, Bian Xiao will give you a concrete report.

Chester Carlson was originally a lawyer, not an inventor specializing in invention. He is just a part-time researcher and inventor. He works in new york Patent Office. His job requires copying a lot of important documents, and Carson suffers from arthritis, so copying documents makes him feel extremely painful. For this reason, he was encouraged and wanted to create something that could copy words quickly and simply, so Carlson.

Then after his repeated experiments and attempts, he made it with a chip covered with sulfur, and the first copy product came out. He applied for a patent for this technology. Carlson intended to sell his invention to some companies, but because the technology was not particularly mature and perfect, he failed, and no company bought his technology. Until 1944, a non-profit organization in Columbus, Ohio signed a contract with Carlson and then perfected his invention. In the following five years, they made many experiments and repeated attempts, and finally successfully developed this technology. And applied for a patent for the copier. Since then, photocopiers have been widely used in our lives.

We are also very grateful to Carlson for this great invention, because it relieves a lot of pressure on our work and study.
