Abstract
An automatic document feeder for conveying a document on a platen glass. Back-up rollers for pressing a conveyer belt against the platen glass are loosely supported by a body frame. The shafts of a driving roller and a driven roller for rotating the conveyer belt, and the supporting member of the back-up rollers each have an end which is detachable from the body frame. The body frame has a first frame pivoted on a copying machine and a second frame for holding the conveyer belt and its motor. The second frame is connected with the first frame such that the second frame is movable from and to the platen glass with a specified range, and further the second frame is urged in a direction separating from the platen glass. The second frame is also movable in a direction perpendicular to a direction in which the pivot of the first frame extends.
