Patent ID: 7573619

Claim:
A paper feeding mechanism, for carrying a paper passing through a scanning station having a scanning module for capturing an image of the paper, the paper feeding mechanism comprising: a partition, disposed corresponding to the scanning station, wherein a first paper feeding channel is formed between the partition and the scanning station, and a second paper feeding channel is formed on another side of the partition, the first paper feeding channel has a first end and a second end while the second paper feeding channel has a third end corresponding to the second end and a fourth end corresponding to the first end; a paper transporting device, for transporting the paper passing over the side of the partition through the first paper feeding channel with a first page of the paper facing the scanning module, then after the paper is flipped for a second page of the paper facing the scanning module, selectively carrying the paper passing through the first paper feeding channel or the second paper feeding channel, the paper transporting device comprises: a paper transporting channel, having an entrance end and an exit end, wherein the paper enters the paper transporting channel via the entrance end, and leaves the paper transporting channel via the exit end, wherein the paper transporting channel is connected to the first paper feeding channel and the second paper feeding channel to form a paper feeding route; and a plurality of transporting rollers, for transporting the paper to pass through the paper transporting channel; and a switching member, for guiding the paper flipped to pass through the second paper feeding channel or to return to the first paper feeding channel with the second page of the paper facing the scanning module; wherein the paper is transported to the first paper feeding channel through the first end, and leaves the first paper feeding channel through the second end; then the paper selectively enters the second paper feeding channel through the third end, and leaves the second paper feeding channel through the fourth end, or the switching member guides the paper to return to the first paper feeding channel.
