There are in use today many kinds of copiers or copying machines utilizing electromechanical, photographic or other techniques, which copy the whole of an image and reproduce one or more copies of the image as a continuous operation. The typical office copier features a machine on which a document to be copied is placed after which a button usually is depressed to actuate that machine. Through a photographic exposure process, the machine delivers a copy of the document that originally was placed on top. Copy machines contain an image processing unit that includes a scanner which scans an input image. When the input image is scanned, the processing unit detects if input data is text or a continuous tone image by detecting edges of text objects as well as the color of the text objects. The image processing unit then applies an appropriate image process to the contents of the input image based on the type of image data detected. Generally, a copier has a paper feed mechanism and a sheet or copy discharge mechanism at laterally opposite sides thereof as viewed from the side where one is expected to operate the copier, i.e. the operating side. An automatic document feeder is a common equipment with many modern copiers and is provided on a glass platen for copying multiple documents efficiently. An electrophotographic copier is provided with an optical system including a light source, mirrors and a lens to focus a beam of light reflected from an original document to be copied on a photosensitive body to form thereon a latent image. Digital copiers are image processing devices which scan an image, store a digital representation of the image in memory, and print the digital representation of the image. In order to print the digitized images at a rate similar to rates produced by conventional analog copiers which never store a digital representation of the image but use optical components such as mirrors and lenses to generate an image on a photoconductive drum or belt, a very large amount of data must be moved at a high rate of speed.
