Problems solved by technology

In this way, due to the large change of force on the object to be scanned in the paper feeding channel (instantaneous generation and release of resistance between the object to be scanned and the roller group), the speed of travel is easy to fluctuate, so it is easy to cause vibration and deformation of the scanned image. like Figure 9 shown

Abstract

A scanner includes an image capturing module, a driving roller set, an idler set and a guiding structure. The image capturing module captures the image of the object to be scanned, the driving roller set drives the object to be scanned to move in the paper feeding direction and the idler set presses the object to be scanned elastically to prevent the object to be scanned from moving in the direction offsetting from the paper feeding direction. A paper feeding passage is formed between the driving roller set and the idler set, and the guiding structure is disposed in front of the paper feeding passage and used for guiding a normal direction of a front edge of the object to be scanned to be at a skew angle substantially not equal to 0 degree with respect to the paper feeding direction. Therefore, the present invention can effectively reduce the variation of the bearing force of the object to be scanned when traveling in the paper feeding passage, thereby preventing the scanned image from being deformed.

Description

technical field [0001] The invention relates to a guiding structure for a scanner and the scanner, in particular to a guiding structure and the scanner for preventing deformation of scanned images. Background technique [0002] In order to meet the needs of users, most of the currently commercially available scanners can support paper and cards of different thicknesses. Since the thickness of the card generally falls between 0.8 and 1.25 mm, and the thickness of the paper is about 0.1 mm, the difference is quite large, so the idler of the scanner is usually provided with an elastic member, so that the idler can cooperate with the object to be scanned to compress The elastic member moves up and down relative to the driving wheel, so that the height of the paper feeding channel between the idle wheel and the driving wheel can be adjusted according to the thickness of the object to be scanned. [0003] However, in this design, if the object to be scanned is thicker, the deform...
