"In computing, an image scanner\u2014often abbreviated to just scanner, although the term is ambiguous out of context (barcode scanner, CAT scanner, etc.)\u2014is a device that optically scans images, printed text, handwriting, or an object, and converts it to a digital image. Commonly used in offices are variations of the desktop flatbed scanner where the document is placed on a glass window for scanning."@en .
