Image scanner

An image scanner is a device that optically scans images, printed text, handwriting, or an object and converts it to a digital image. The most common type of scanner used in the home and the office is the flatbed scanner, where the document is placed on a glass bed. A sheetfed scanner, which moves the page across an image sensor using a series of rollers, may be used to scan one page of a document at a time or multiple pages, as in an automatic document feeder.

A handheld scanner is a portable version of an image scanner that can be used on any flat surface.
Scans are typically downloaded to the computer that the scanner is connected to, although some scanners are able to store scans on standalone flash media.
