| 摘要 |
The present invention provides a paper feeding apparatus for use in an image reader, e.g. such as an image scanner, which is designed especially to prevent overlap feeding of sheets of paper, and can adjust both the pressing forces between a hopper for carrying sheets of paper in a stacked manner and a pickup roller for paper feeding and between a parting roller and a retard roller for the prevention of overlap feeding. The paper feeding apparatus of the present invention serves to feed the sheets of paper one by one from the hopper and to restrict overlap feeding by the parting roller and the retard roller. This optimizes the paper feeding in the pass line from the hopper to the preventing mechanism for overlap feeding, thereby achieving a secure prevention overlap feeding.
