Abstract
A multiple-resolution scanning device introduces an image information obtained by scanning a document into a light folding device and the image information is reflected in the light folding device. The image information comes out from the light folding device and received and reflected by a final reflection mirror unit, and passes through a lens unit and then focused on an optical sensor. By adjusting the light folding device or the final reflection mirror unit, or by adjusting the light source and the light folding device to change the position or angle thereof to achieve the purpose of changing the path of light of the image information and obtain the scanned results having different resolutions.
