Abstract: A lamp shade moving mechanism for transparency scanning includes a guiding rack, a sliding block, a driving motor and a belt. Grooves are formed on inside wall of two lateral sides of guiding rack to hold and lead sliding block. Driving motor and belt move sliding block to make a linear to-and-fro movement along guiding rack. A lamp shade is disposed on the sliding block, characterized by having simple components and capable of performing high speed scanning.

Abstract: An improved transmission system for a document feeder, in which a constant one-way-rotating gear train is mounted in an output zone so as to cause a transmission shaft in the output zone to rotate in one direction only to send out a sheet of document no matter the driving gear rotates clockwise or counter-clockwise; therefore, as soon as a first sheet of document moves out of the scanning line without moving out of the output zone, the driving gear will change its rotation clockwise so as to have a next sheet of document fed into the scanning zone; therefore, the feeding distance between two sheets of document will be reduced, and consequently the whole feeding time for a document will be reduced, too.
Abstract translation: 一种用于文件馈送器的改进的传输系统，其中恒定的单向旋转齿轮系安装在输出区域中，以便使得输出区域中的传动轴在一个方向上旋转，仅发出一张文件 无论主动齿轮顺时针还是逆时针旋转; 因此，只要第一张原稿从扫描线移出而不移出输出区域，驱动齿轮将顺时针转动其旋转，以便将下一张原稿送入扫描区域; 因此，两纸张之间的进纸距离将减小，因此文件的整个进纸时间也将减少。

Abstract: An improvement of brightness compensation for a lamp shade in an optical scanner includes a plurality of projections to make a reflector in the lamp shade to form a greater curvature on its lateral sides, thus increase the light-condensing capability of the reflector, and thereby improve brilliance uniformity of a lamp tube.
Abstract translation: 光学扫描器中的灯罩的亮度补偿的改进包括多个突起，以使灯罩中的反射器在其侧面上形成更大的曲率，从而提高反射器的聚光能力，从而提高 灯管的辉度均匀性。
