Abstract
A scanner with a movable mirror set in the scanning module for increasing the resolution of scanned images. The scanner includes a housing that makes use of a set of movable mirrors. When the mirrors move, the distance traveled by the light from the document to the CCD changes, resulting in a different optical resolution. The lens moves in order to maintain the proper focal distance between the document and the CCD. A driving device coordinates the movement of the lens and the moveable mirrors.
