History of photocopiersWho invented the copier company's patent attorney, is the P.R. Mallory and Co Inc named Chester Carlson. b.s. physics, which was successful, and worked as a research engineer at Bell Telephone Laboratories, the company first turned to working as a patent attorney at the Office of the patent, which he must do this to a copy of the documents is a lot of duplication in that way, but not to make a copy of the document and the copy cannot be made fast enough, such as the use of carbon paper, photographs, documents, directly with a camera and a typewriter, repeat. This makes them think that Chester the need to impress. If the document is a tool to make a copy that is accurate and fast. So he spent the evening in the khluk library for months copy knowledge as he will find out. After previous research studies. He found an interesting research of physics, Hungarian name Paul Selenyi people mentioned images generated by static electricity. (Electrostatic image) using certain types of materials that can be better when you have a power light come fall, impact. To prove it, his research and his assistant Otto Kornei trial brought German physics student is substance, zinc-coated on sulfur coming. Then scrub with a cloth, zinc sheet, occurring static electricity. Some of the glass sheet and type the text "10-22-38 ASTORIA" placed on the sheet of zinc per channel every light comes off so that the environment is dark as much as possible and to radiate light from a light bulb and a glass sheet glass for a moment pulled out and sprayed powder Lai co Pro medium sulfur coating on. Gently blowing the powder Pro medium chrome browser that continuously light phaeo. As a result, some pro liquid powder medium chrome browser running on the surface looks as close to the text on a sheet of glass. After that, he makes the text appear to the system by bringing on wax paper and let the wax paper melt heat and vacuum to remove the ink from the plate, zinc, stuck on the paper. In the end, a copy of the first sheet of its document on October 22 1938, or 76 years ago. He brought those techniques and process to patent and the company offers a product that actually works, but there are no results, it appears that where companies interested in at all. In the period of 6 years (r. 1939-1944) is charged with more than 20 companies rejected the proposal, including the two giant companies, IBM and General Electric Company ayangborisat he felt despondency when Don refused several times, but did not stop the company presented to the other institutions, Battelle Memorial Institute, in the end, the research unit is not exploitation.Pay attention, though, and made a contract to develop his invention. Later, Battelle Memorial Institute in 1947 Institute has developed a contract signed with the company Haloid copier manufacturer and supplier of paper prints. In the next two years the company Haloid, then launched the first version of the Model name Copier A but is not recognized because each copy of the document used for almost 5 minutes, and use than to be taken to follow the step to step 14. Additionally, if you copy more than 12 sets of problems, so the company Haloid, thus improving A Model aircraft by up to 10 years, it takes a long time, until 1959, the company, renamed as XEROX already has launched the Model 914 Copier and succeeded in selling quickly. As a result, a new Cathedral, Chester Carlson became a millionaire.
