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.
Claims5
A scanner comprising:
- a housing;
- a transparent platform installed on the housing for placing a document;
- a scanning module installed inside the housing for scanning the document, the
- scanning module comprising:
- a first mirror set fixed inside the scanning module for reflecting light transmitted from the document;
- a second mirror set moveably installed inside the scanning module for changing an optical path of the light transmitted from the document so as to change resolution of a scanned image;
- and
- a lens set moveably installed inside the scanning module for focusing the light transmitted from the first and second mirror sets;
- wherein when the second mirror set is moved to change the resolution of the scanned image, the lens set will move correspondingly to adjust the focus of the light transmitted from the first and second mirror sets.
