a machine that converts documents, drawings or photographs into machine-readable form

COMMENT: A scanner can be a device using photoelectric cells as in an image digitiser, or a device that samples data from a process. One type of scanner reads the barcode on the product label using a laser beam and photodiode; another can read text and by recognising characters, stores them as data on a computer; yet another type will scan colour originals and carry out colour separations.
