Abstract
A paper deskew device for an automatic document feeder includes a transport roller assembly, a deskew roller assembly, and a power transmission mechanism. The transport roller assembly includes a first gear. The deskew roller assembly includes a second gear. Before a front edge of a paper is contacted with the deskew roller assembly, the first gear links the power transmission mechanism and the second gear, so that the transport roller assembly and the deskew roller assembly are respectively rotated in a first direction and a second direction. Once the front edge of the paper is contacted with the deskew roller assembly, the deskew roller assembly is continuously rotated in a second direction for a second direction for correcting the skew phenomenon of the paper. Afterwards, the second gear and the deskew roller assembly are driven by the first gear to be rotated in the first direction to transport the paper.
