Problems solved by technology

[0008] However, we have found that although this structure can achieve the purpose of adjusting the reflection angle of the reflector 25 and the path of its reflected light, the possible length of the screw 23 cannot be designed due to the concept of a thinner scanning module. It is too long, so when the user adjusts by rotating the screw 23, he can only make rough adjustments and cannot make fine or precise fine adjustments. On the other hand, the design of the screws 23 and the screw 23 And the design of the corresponding hook 24 can only be adjusted in a single direction and cannot be adjusted in the opposite direction; therefore, the main purpose of the present invention is to improve the previously mentioned patent application. defects, so that an adjustment device can be designed that can be finer in structure and more convenient in operation

Embodiment Construction

[0028]Please refer to FIG. 3a, which is a schematic diagram of the scanning module 300 of the present invention. As shown in the figure, the scanning module 300 has a base 30, a mirror base 31, a shaft 32, a mirror element 330, and a gear set 34; from the description of the background art, it can be seen that in the general scanning module There are several mirrors in the internal structure to facilitate the reflection and imaging of the light of the image when the document is scanned. In the description of this embodiment, we simplify it and use only one mirror to illustrate the same concept. At the same time, it can be used in the manufacturing and adjustment process of other mirror structures; in addition, other structures such as known light sources, optical lenses, image sensors, etc. are not shown in this figure, but only the characteristic structure of the present invention. For explanation and description.

[0029] As shown in Figure 3a, in this preferred embodiment of the...

Abstract

A scanning module of image scanner consists of a base, a reflector seat set on said base, a shaft set on reflector seat in rotary mode, a reflector fixed on said shaft and a gear set being combined with said shaft in rotary mode and being used to vary angle of reflector set on said shaft.

Description

Technical field [0001] The invention relates to a scanning module of an image scanner, in particular to a scanning module capable of adjusting the angle of the internal mirror. Background technique [0002] With the advancement of modern technology, the use of image processing application devices by modern people has become more and more common. As the average user is well-known, image scanners are already an important computer peripheral device that scans document images. It can be converted into digital files for storage and transmission, or for further editing and printing. It has become an important and indispensable image processing device when modern people use computers. [0003] Since most of the general image scanners are designed with a platform structure, and through this platform design, the device itself can scan most of the documents, whether it is a single sheet or a thick book, but It is also because such a device will occupy a certain working space of the user in...
