ABSTRACT:
Documents stacked in a document tray are fed from the lowermost sheet by a feeding belt and then by a feeding belt to a light exposure station via feeding rollers, and after light exposure are recirculated onto the uppermost sheet of the document tray by a inverted feeding roller via an ejection roller. When the documents are double-sided, they are invertedly fed in the direction of a feeding path by the feeding roller, fed to the light exposure station, and each side of the documents presented for light exposure. Here, when trouble occurs in the copying unit, the document in the feeding path is returned to the document tray while recirculative feeding of the documents remaining in the document tray is performed for automatic restoration of the documents to their originally stacked state when returned to the tray. Therefore, only the minimum necessary number of documents are fed through the inverted feeding path. Thus, restoration of the initial stacked state of the documents may be carried out automatically for shortening of the time required therefor.
