摘要
A flatbed scanner includes a flatbed document scanner body accommodating a transparent plate for supporting a physical document and a document cover, which includes a sheet member with an expanse covering at least a substantial area of the transparent plate. The rectangular document cover has an underside and a movable carriage extending across the rectangular transparent plate in a transverse direction. The movable carriage carries a camera or an optical system for a camera. The sheet member of the rectangular document cover is magnetic or carries one or more magnetic plates, so as to be magnetically attracted towards the movable carriage and exert a pressing force on the physical document when supported on the rectangular transparent plate. A compressing force is thereby applied to an original document resting at an area at which the movable carriage currently is located while scanning a line of the original document.
