Abstract: An image forming apparatus having an automatic document feeding unit so as to successively read documents is disclosed. The image forming apparatus includes an image forming unit to form an image on a printing medium, an image reading unit pivotally coupled to an upper portion of the image forming unit to expose and shield a top of the image forming unit, an automatic document feeding unit pivotally coupled to an upper portion of the image reading unit to expose and shield a top of the image reading unit, and a locking device to selectively expose any one of the top of the image forming unit and the top of the image reading unit. Since the locking device prevents the top of the image forming unit and the top of the image reading unit from being simultaneously exposed, the automatic document feeding unit can be prevented from being damaged due to the simultaneous exposure of the top of the image forming unit and the top of the image reading unit.

Abstract: An image reading apparatus having an auto document feeder includes a simplex path for simplex reading, a duplex path which is distinguishable from the simplex path and conveys a plurality of sheets of paper at different positions in a duplex reading mode, a path selecting element, and a flipping element which allows a second side of paper to be read first. Accordingly, in the duplex reading mode, a separation distance between sheets of paper is reduced, a returning path is reduced, the second side of paper is first read, and the paper is collated and then discharged after both sides of paper are read, thereby significantly improving duplex reading efficiency.

Abstract: An automatic document feeder of an image forming apparatus capable of improving a duplex scanning or printing (copying) efficiency includes a single scan path having a document admission passage to admit a document to a document scanning part and a document discharge passage to discharge the scanned document, a duplex scan path having a first document reversing and waiting passage diverged separately from the document discharge passage on the single scan path at the rear of the document scanning part to reverse the document, one surface of which is scanned, and admit the reversed document again to the document scanning part, and a document re-reversing path having a second document reversing and waiting passage diverged separately from the document discharge passage on the single scan path at the rear of the document scanning part to reverse the document, both surfaces of which are scanned, again and send the re-reversed document to the document discharge passage.

Abstract: 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.
