摘要:
A circulating type of automatic document feeding apparatus comprising a document hopper(2) which is adapted to take out the top document from the hopper or take it out from the bottom to return in onto the topmost side a first carrying means(7) for carrying the document(X) from the document hopper to a first exposure portion, a document presentation portion (5) having the first exposure portion and the second exposure portion, a second carrying means (8) which is equipped with an inside and outside inverting means for inverting the carrying direction of the document between the first exposure portion and the second exposure portion, and a third carrying means (9) for returning the document to the document hopper from the second exposure portion. One face of the duplex document may be exposed in the first exposure portion to continuously expose the other face thereof in the second exposure portion, so that the copying operation of the duplex document may be effected at higher speeds and furthermore with considerably reduced operations on the part of the operator.

An armored unit (12) includes a side cover (30) and a guide member (40). When sheet jam operation is carried out, a fixing unit (36) is pulled out with the armored unit (12), and then is pushed to the rear side. This operation unlocks the lock member (52) provided in the guide member (40), and a shoulder screw (51) moves in a guide hole (40a). Thus, the fixing unit (36) is moved from the pulled out position toward the rear side and toward the main body of image forming device to be shifted to a receding position. On this account, it is possible to provide an image forming device ensuring sufficient space for removing a jammed sheet by hand with a small opening space.
