History of copiers , copier was invented. The company's patent attorney PR Mallory and Co Inc. named Chester Carlson, who completed a Bachelor in Physics. And worked as a research engineer at Bell Telephone Laboratories before turning to work as a patent attorney at the patent office. Which is causing him to make copies of documents and a lot of duplication in those days, but not to make copies of documents. And still can not make copies quickly enough, such as using carbon paper. Direct imaging with a camera. And bringing the document to a typist reprinted here makes Chester idea was that these offices. Certainly appreciate If there is a tool to copy accurately and quickly. So he spent the evening immersed in the library for months. To learn about reproduction as much as he can find. After studying previous research. His research found that the interest of the Hungarian physicist named Paul Selenyi that the image generated by static electricity. (Electrostatic image), using some materials that conduct electricity better when light is incident. To prove such research, he and his assistant, the German physicist Otto Kornei. The pilot sulfur coating on a zinc plate. After that, contrary to ESD zinc plate with a handkerchief. Then the thin glass sheets that typing "10-22-38 ASTORIA" put on a zinc plate. Later closed all channels light. So that the environment is dark as much as possible. And emits light from the lamp onto a glass plate for a moment. Then pull out a sheet of glass Live Cattle Depot Stadium and throws powder on the sulfur coating powder Live Cattle Depot Stadium, gently blow them out gently. The result is powder Live Cattle Depot Stadium, some mounted on a surface similar to the text on a sheet of glass. Then he makes the text appear permanently grafted to the paper. And heating Wax melts and absorbs the ink from the paper zinc sheets stuck on the paper. The first copy of the disc was born on October 22, 1938 or when 76 years ago he led the patented process and techniques. And presented to various companies To develop a product that actually works. The results show that the company is not interested at all in the six-year period (AD 1939-1944) by more than 20 companies rejected the proposal includes two giant companies like IBM and General Electric when he felt discouraged. rejected several times, but did not stop to offer other companies. The research institute Battelle Memorial Institute, a non-profit was interested. And a contract to develop his invention, later in 1947, the Institute Battelle Memorial Institute have signed a development contract with the Haloid company copier manufacturer and supplier of printing paper in the next two years, Haloid company was launched. Copy the first name Model A but not accepted. The copying each piece takes almost a minute. And work harder to have taken steps to 14 steps, if more than 12 sets of reproduction problems, thus improving the company Haloid Model A takes up to 10 years until 1959, the company. which renamed the XEROX successfully launched photocopier Model 914 comes out and succeed in selling rapidly, resulting Chester Carlson became the new Nawab.
