As used in this article, OCi consists of optical scanning equipment cap. able of reading typewritten and computcr-printed mate. ral and converting it to a conpuler-acceptable code and media. The OCR Input method Is dis. inguished from other automatic input conversion methods such as magnetic Ink character recognition and optical mark reading (another type of optical scanning) In that the characters to be read are recognized by their images rather than magnetically or position. ally. OCR works on the principle of light reflectance. A strong light is passed over the source document and the machinre senses those areas which do not reflect the light. The areas not reflecting light (the chara ter images) are compared with character images stored in the machine's memory. The matched character is then transferred to the computer for direct input or Is written on a computer.acceptablo medium such as magnetic tape. Certain features are common to all types of OCR machines: a paper transport system to movo the source documents through the machine; a rec. ognhion head to read the characters on the source documents; a memory to compare the characters read with those stored In mcmory; a code converter to convert the characters into computer. acceptable code; and a control unit. It is estimated that there are 500 or more optical scanning machines In use In die United States at present. A sur- vey of about 2,200 computer installa* tions by Business Automation shows that only about 4 percent of the instal- lations use optical scannng equipment as their basic input device and that keypunching is still the basic Input method in about 85 percent of the in. stallations. Electronic News estimates that optical scanning input volume now equals about 1 percent of the present I EDP Salary Siuly-t968, Busteje Aonaiom.hn. 15 (June !9M8), y 42.
