Example Embodiment

[0042] Example 1

[0043]The present invention provides a belt tension adjusting device. With the elastic force of the belt tension adjusting device, the partial bending of the transmission belt is maintained to maintain a proper tension, and the tension of the transmission belt can be easily adjusted to facilitate assembly Install and remove the drive belt during assembly, maintenance or adjustment. The aforementioned belt tension adjustment device can be achieved by, for example, a leaf spring. With the elastic force of the leaf spring, the partial bending of the transmission belt maintains an appropriate tension, and the tension of the transmission belt can be easily adjusted by this, and it is convenient to install or disassemble the transmission belt during assembly, maintenance or adjustment. . If it is to avoid the elastic fatigue of the leaf spring due to environmental or use factors, a tension spring, such as a tension coil spring, can be added to the belt tension adjustm...

Abstract

The adjusting device includes a plate spring and/or a tension spring. Elastic force generated from the plate spring or from the combination of the plate spring and the tension spring makes bending ofthe driving belt locally so as to maintain a proper tensile force. Thus, it is easy to adjust tension as well as to install or disassembly-driving belts when assembling maintaining or adjusting operations are carried out.

Description

technical field [0001] The present invention relates to a belt tension adjustment device, and in particular to a belt tension adjustment device for adjusting the tension of a transmission belt of an optical scanning module, and an optical scanner using the adjustment device. Background technique [0002] After the input, processing and processing of images has become a popular interest, scanners have become one of the basic equipment for many computer users. It can scan text or image data of documents, magazines, books, pictures, etc. input into a computer and processed. Among all kinds of scanners, the flatbed scanner is the most commonly used one. In the flatbed scanner, the scanning module is installed under a transparent platform in a way that can be pulled back and forth to scan documents placed on the transparent platform. . Moreover, the scanning module itself has no power, so it needs transmission mechanisms such as servo motors, gears, belts, etc. to drive it. Wh...
