The function of OCR, input device is to scan the characters on the page, one by one and then compares them with characters stored in the computer's memory.
there is no reason at all.
OCR (optical character recognition) is a function of a scanner system for a computer used to take paper documents (or what have you) with writing on them and convert it to a format that a PC can read and edit. This, because it's a function of a scanner, makes it an "input" device. Hope that helps!
