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.

Abstract: A scanner includes a body with an angled glass window and a movable optical module is connected in the body of the scanner. The optical module is moved in parallel with the gutter of the book to be scanned. The pages are matched on the angled glass window and the movable optical module moving in parallel with the gutter can scan images on the two consecutive pages of the book. The images at the gutter of the book can be clearly scanned.
