Abstract: Provided is a transparency scanner having a light source which is synchronously moved with the image sensor of the scanner by using magnetic force to establish a solid connection between the transparency scanning light source and the image sensor while scanning a transparency. A motor is used to synchronously move the transparency scanning light source and the image sensor to avoid the errors produced by driving devices such as different motors or gears, etc. Therefore, synchronous movement of the transparency scanning light source and the image sensor can be ensured, and the deterioration of the scanning quality due to various distributions of the intensity of the light source can also be avoided.

Abstract: An apparatus for point by point and line by line scanning of originals or documents includes a fixed, transparent original carrier for an original. An illumination carrier is disposed above and parallel to the original carrier. An illumination unit is fixed to the illumination carrier for illuminating the original line by line. A base carrier parallel to the illumination carrier is disposed under the original carrier and an optoelectronic scanning element for converting scanning light into picture signals is fixed thereon. The illumination carrier and the base carrier are interconnected by a U-shaped connecting element. The connecting element has a rotary joint for pivoting the illumination carrier away from the original carrier with the illumination unit to facilitate access to the original carrier. The illumination unit and the scanning element perform a perpendicularly oriented advancing movement in relation to scanning lines through the use of linear guides, in order to scan a surface of the original.

Abstract: The present invention provides an image scanner comprising an automatic document feeder and a moveable light source. The image scanner uses a sensing device to detect the position of a lid, and uses a switch mechanism to control the power output of a motor. When the lid is at an “on” position, the power output of the motor will be transmitted to the automatic document feeder to scan opaque documents. When the lid is at an “off ” position, the power output of the motor will be transmitted to the light source to scan transparent documents. The transparent documents can be scanned without additional locating devices to locate transparent documents thus making the image scanner multi-functional and easy to use.

Abstract: A light diverting channel for use in a scanner. The channel is incorporated into the cover of a flat bed scanner and transmits light from the lamps positioned longitudinally along the scanner, up through the side of the channel, and through a central region or sheet of the channel, and then down through objects to be scanned. The light diverting channel thereby more efficiently uses the light generated by the lamps and more evenly disburses the light over and through the object to be scanned.

Abstract: A reflective/transmissive scanner having a transmissive mode light source that is synchronously moved with the image-retrieving device. The scanner is provided with a scanner body having an upper surface with slots formed therethrough and a first transparent plate disposed in an aperture in the upper surface of the scanner body on which an object to be scanned is placed. A second transparent plate is provided in the lower surface of the scanner lid, corresponding slots being formed in the second transparent plate. A first support frame is disposed within the scanner body, with a reflective light source and an image retrieving device disposed thereupon, and a second support frame is disposed within the scanner lid, with a transmissive mode light source disposed thereupon. When the scanner lid is in a closed position, the first support frame and the second support frame are physically engaged through the slots, allowing the alignment between the transmissive mode light source and the image-retrieving device to be synchronously maintained.
