WORLDS FIRST PHOTO COPY MACHINE ... The first copy machine invented was called the Mimeograph. Thomas Edison, famous inventor of the light bulb, invented the Mimeograph. This device was also known as a stencil duplicator. A stencil duplicator is a low-cost printing press that works by forcing ink through a stencil onto paper. Thomas Edison received US patent 180,857 for “Autographic Printing” on August 8, 1870. The patent covered the electric pen, used for making the stencil, and the flatbed duplicating press. In 1880 Edison obtained a further patent, US 224,665: “Method of Preparing Autographic Stencils for Printing”, which covered the making of stencils using a file plate, a grooved metal plate on which the stencil was placed which perforated the stencil when written on with a blunt metal stylus. A mimeograph machine works as follows: • Special mimeograph or duplicator ink is applied as appropriate to the particular machine. • Paper to be printed is placed in the paper tray. • A prepared stencil is wrapped tautly and smoothly around the cylinder and secured at one or both ends, depending on the machine. • As the cylinder is rotated, a pressure roller inside the machine presses paper against the cylinder. • The roller forces the ink through the openings that were cut in the stencil onto the paper. During the Industrial Revolution, the growth of business caused a need for a more efficient means of duplicating documents than copying. Copying was originally done with carbon paper. This is what brought on the invention of the mimeograph and then later came the Photostat machine. In 1907, the Photostat copy machine was invented by Oscar Gregory. This machine was too large to use in the office environment and the machine required a trained operator. This was very expensive and could only be afforded by larger companies with the extra space and money. George C. Beilder of Oklahoma City founded the Rectigraph Company in 1906 or 1907. The Rectigraph company was acquired by Haloid company in 1935. In 1948 Haloid Purchased the rights to produce Chester Carlson’s xerographic equipment and in 1958 the firm was reorganized to Haloid Xerox, Inc., which in 1961 was renamed Xerox Corporation. The Xerox machine was made by the means of electrostatic copying. This machine, also known as a photocopier, is a machine that makes paper copies of documents and other visual images quickly and inexpensively. Copy machines have revolutionized the way we do business today. Copiers can now produce duplicate transcriptions up to rate of 150ppm. The first copy machine, using stencils, wasn’t quite that fast but also produced copies at a faster rate. Modern day copiers now integrate into our computer networks and the cloud. As time goes on, technology will keep evolving and business will become more efficient. It has to make you wonder- where will we be in another 50 years?
