Description
- The present invention relates to a scanning device and, in particular, to a scanning device for double-sided scanning and a paper feeding module thereof.
- An auto document feeder (ADF) is a paper feeding mechanism for a photocopying machine. The ADF can convey a whole stack of paper sheets one by one to make them pass through a scanner of the photocopying machine for scanning operations. A common photocopying machine can only scan one side of the paper sheet. By adding another scanner in the ADF, the other side of the paper sheet can also be scanned, so both sides of the paper sheet can be scanned in one paper feeding operation.
