Abstract
A double side scanner module which consists of a U-shaped inversion device and two image information reading devices is provided for reading images on the two sides of an original in a single pass. The U-shaped inversion device has two ends for providing a paper feeding path and a paper output path respectively. The two ends are at the same side for the convenience of operation. At both of the two ends, there is a glass window. Beneath each of the glass windows, there is an image information reading device. When an original is fed into the paper feeding end and conveyed through the first glass window, the first image information reading device starts to read the image on the first side of the original. When the original is conveyed through the U-shaped inversion device, the scanned side will be inverted to the other side. Consequently, when the original is conveyed through the second glass window, the second image information reading device can read the image on the second side of the original and complete the double side scanning.
