Abstract
The present invention relates to an optical scanning module used in an optical scanner for scanning a document. The optical scanning module comprises a housing with an opening installed on its top for receiving light transmitted from the document, an optical sensor installed inside the housing for converting the light transmitted from the document into corresponding image signals, a mirror set comprising a plurality of reflective mirrors installed inside the housing for passing the light transmitted from the document to the optical sensor, and a lens set installed between the optical sensor and the mirror set inside the housing for focusing the light transmitted from the document onto the optical sensor. The lens set and the optical sensor are movably installed inside the housing, or at least one reflective mirror of the mirror set is moveably installed inside the housing over which the length of an optical path from the document to the lens set can be adjusted by moving both the lens set and optical sensor or by moving the movable reflective mirror to calibrate the accumulated tolerance generated by various components of the scanning module.
