Techopedia Explains Flatbed Scanner
Unlike other types of scanners, a flatbed scanner only requires the user to lay the document onto the glass and close the lid. Almost all flatbed scanners have an adjustable lid which can be raised to allow thicker materials to be scanned. A transparent media adapter, found in some flatbed scanners, can scan film and glass negatives. Some flatbed scanners can also have additional features such as automatic document feeders and wireless or Bluetooth connectivity.
