Guiding structure for use with scanner that prevent deformation of scanned images, and scanner

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. 种扫描仪包含有
