Abstract
A scanner module with a single image information reading device is provided to read both sides of an original. The scanner module mainly comprises: a paper feeding device, and a paper output device for providing an I/O path for the original. The paper feeding device is connected to a scan station. The scan station comprises a glass window and a pinch roller which locates against the glass window. Beneath the glass window, there is an image information reading device. Under the guidance of the pinch roller, an original will be conveyed progressively from the paper feeding device and through the glass window for the image information reading device to read the first side of the original. The original will be inverted while passing through an inversion device. At the mouth of the inversion device, there is a document sensor. When the original leaves the inversion device, the sensor will generate a control signal to the pinch roller and enable the pinch roller to rotate in an opposite direction. The inverted original will be guided through the glass window with the guidance of the pinch roller. Consequently, the image information reading device can read the other side of the original.
