Abstract:
An image-scanning module for a scanner at least comprising:a light-radiating device for emitting light to scan an object, comprising a first lighting portion and two second lighting portions extended from two ends of the first lighting portion; wherein the first lighting portion and the two second lighting portions are on the same plane; a focusing-and-imaging device for focusing the reflected light from said scanned object and for forming an image; and an image receiving device for receiving and processing said image; wherein the light-radiating device is disposed in a way that the plane formed by the first lighting portion and the two second lighting portions is perpendicular to the plane where the scanned object is placed, whereby the reflected light from said scanned object is not masked by the two lighting portions and the length of first lighting portion can be reduced, thereby downsizing image-scanning devices using the image-scanning module.
