Abstract: A scanner including at least a casing, a scanning platform, a carriage and a lateral reversing device is provided. The scanning platform is installed on the covering panel of the casing and is used to accommodate at least one document. The carriage is movably installed in the casing and will transmit a scan-finished signal after having scanned the front side of a document. The lateral reversing device, which is installed at a lateral side of the scanning platform, is equipped with a control unit and is used to turn the document over for the reverse side of the document to be scanned after the control unit has received the scan-finished signal.

Abstract: A scanning module for scanning a document is provided. The scanning module comprises: a chassis; a light source on the chassis for emitting a light ray onto the document; a plurality of reflectors inside the chassis; a lens inside the chassis; an image sensing device inside the chassis, an image of the document being reflected by the plurality of reflectors and formed on the image sensing device, the image sensing device including a plurality of sensing cells; and a plurality of microlenses on the plurality of sensing cells, each of the plurality of microlenses having a top surface and a bottom surface, the top surface having a plurality of notches as an input window for changing an incident angle of the light ray, the bottom surface having a plurality of round curves as an output window for further focusing the light ray.

Abstract: A scanner with an adjustable opening for receiving light at least includes a chassis with two grooves and an adjustable grating board. The grooves are positioned at two ends of a first surface on the chassis. A long, narrow opening is built into the first surface so that the light reflected by the document can enter the chassis. The grating board positioned on the built-in opening includes a grating opening and at least two engaging bars. The grooves are positioned and shaped according to shape of the engaging bars so that the grooves can engage with the engaging bars. The grating board can be moved horizontally as the engaging bars slide along the grooves. The grating board is fixed in a precise position and calibrated to reduce unwanted light from entering the chassis.

Abstract: A light gathering apparatus of a scanner is disclosed. A light source module of the light gathering apparatus is separated from a scanning module and is disposed on the main body of the scanner chassis, and a light gathering device and a light guiding device are used to guide light onto a scanning line of an original document. Because the light source module is separated from the scanning module, it is beneficial for miniaturization design of the scanner, and the scanner is easy to be cooled down, thereby decreasing noise and distortion resulted from a charged coupled device (CCD), reflection mirrors, or the main body of the scanning module being heated.

Abstract: A light collection member with a reflection part is installed on an optical chassis and at least includes a reflection piece in an elliptic columnar, wherein the reflection piece has a first focusing point and a second focusing point, and the second focusing point is about located on a scanning line on a document; a light source being used to supply the needed light beam for the scanning process; a light collection mask being used to cover the light source. The light collection mask has an opening. The opening is located on the first focusing point of the reflection piece. During the scanning process, the light beam emits from the opening and is focused onto the second focusing point on the scanning line, according to the focusing principle for an elliptic geometric shape.
