The fax comes from the Latin word “facsimile”, which means “to do the same.” The fax system from both the sender and receiver takes advantage of the fact that any text or figure on paper can be transferred from one place to another. In the sending device, the image converted to electrical signals is transmitted to the receiving device via telephone or radio line.
Who invented the fax machine? H2>
The facsimile of the fax machine was taken by Alexander Bain strong> in 1843, Frederick Bakewell exhibited at the Great London Exhibition.
Alexander Bain, a photographer of today’s design, was photographed on November 24, 1924, from New York to London, with a machine that had arrived in 1924 as a result of research by Richard H. Ranger of the American Radio Corporation of America. Previously, fax related work was done. The first fax machine was a German scientist Professor. It was invented by Arthur Korn strong> and constantly improved until the first experiment.
In 1959, the facsimile method, which was briefly called Fax, was used when a newspaper was completely transmitted elsewhere. All the pages of the Asahi Shimbum Newspaper published in Japan were transferred to the second printing press in Saporro, 900 kilometers from Tokyo, where the head office was located.
In 1842, when Alexander Bain first discovered it, the fax machine, which was very crude compared to today’s technology, showed a rapid improvement over time. . Contemporary fax machines were developed in the mid-1970s. After the second half of 1980, Japan developed the digital fax machine.
Nowadays, documents can be sent from computers via modems and service providers that offer this service via the internet.
The most commonly used fax systems are those connected to telephone lines.
The image on the paper passed through a cylinder in the sending device is scanned by a photoelectric detector and converted into electrical signals. These signals, which are obtained based on the intensity of reflection from the black and white regions of the light hitting the paper, are amplified and modulated into sound wave signals which can be transmitted by telephone or radio lines. Demodulating the signals coming to the buyer and transferring them to the paper is done by various methods. Sensitive images, such as photographs, are passed through the paper to the optical photographic film method (this method is used in journalism). Other systems use thermal, electrolytic, electrostatic and printer techniques. In the thermal system, a special paper with carbon and chinchilla is used. By turning to maximum in the sender fax device, the black zone signals generated in the device of the clay layer on the special paper are turned to the maximum in the receiving fax device so that the clay layer in the special paper is burned and the black carbon layer is uncovered. For white areas, signal intensities are the opposite.
In the electrostatic method, the black areas of the transmitted document are brought to the electrostatically charged state on paper in the receiver.
Another technique, the electrolytic method, involves passing the image through the sheet by electrolysis. Share the information multiplied.
