Abstract
A transparency scanning mechanism of a CIS scanner for scanning a transparency includes a plane light source mounted on the upper cover of the scanner, for projecting the transparency. A guide device is mounted on the upper cover and located adjacent to the plane light source for guiding the transparency to face the plane light source. Thus, the CIS scanner may be used to scan the transparency. The scanning mechanism and the upper cover may be made integrally, thereby decreasing cost of fabrication. In addition, the upper cover may be provided with a driving device and/or a retaining device adjacent to the guide device, to mate with movement of the transparency, so that the transparency may be moved conveniently, thereby preventing the transparency from being tilted and deviated.
