A method and apparatus for efficiently scanning a duplex document in which a scan unit sequentially scans both sides of a sheet of a duplex document by moving the sheet across a reader, and a reverse output unit to output the sheet after turning over the sheet. Therefore, since the sheet of a document can be fed and scanned while the second side of the previous sheet of the document is scanned, scanning time can be reduced. Particularly, the reduction in scanning time is very useful when multiple sheets of a duplex document need to be scanned.
