A light-generating device for a scanner is fixedly disposed onto the upper cover of the scanner, and includes a light generating element, a reflective surface, and a semi-transparent plate or a lens. This light generating device is used to replace the conventional flat mask or moveable tube. The light-generating device made according to the present invention may project a homogeneous light onto the exposure with which the chroma difference of the scanned image can be prevented.
