ABSTRACT:
The invention is an automatic paper-feeding structure, which includes: a lifting member, which is arranged at the paper-feeding side of this automatic paper-feeding structure, and on which plural document papers are supported, and which may make the plural document papers skewed to one side and lifted up; a paper-taking member, of which face generates frictional force to the first paper of the document to make the first paper touched by the member's face be fed into the interior of the paper-feeding structure by the paper-taking member; a paper-separating member, which is with the paper-taking member to generate the squeezing function onto the papers and is able to separate the paper, such that the first paper on the document may be separated from other papers thereunder; a paper-feeding member, which receives the papers delivered from the paper-taking member and generates necessary interaction with the paper-separating member and the de-skewing member; a de-skewing member, which makes a de-skewing and delivering job upon the first paper transferred by the paper-feeding member and prevents other document papers from entering the interior of the paper-feeding member; a sensor, which is arranged at another side of the de-skewing member corresponding to the paper to detect if the paper has already entered the de-skewing member; a scan member, which receives the papers delivered by the paper-feeding member and processes a scanning and printing job upon the papers.
