Abstract
The present invention relates to an optical scanning module with two movable lenses that move in opposite directions thus providing two different scanning resolutions. The scanning module comprises a housing with a window which receives light from the document, an optical sensing device for converting the light into corresponding image signals, and a lens module for converging the light onto the optical sensing device. Two parallel tracks are installed within the lens module, each containing a movable lens. A driving device moves either one of the two lenses into the optical track allowing light to be converged through this lens onto the optical sensing device. Each of the two lenses provide different scanning resolutions and methods for converging light.
