ABSTRACT:
An automatic document conveying device for use with an image processing machine having a transparent plate on which to place documents. The device includes an opening-closing frame and a document table. A conveyor roller is rotatably mounted in the opening-closing frame. A document delivery device is provided for delivering sheet-like documents from the document table. The document delivered from the document table is introduced into a required position on the transparent plate by the conveyor roller. The rotation of the conveyor roller in the introducing direction is stopped while the introduced document is still between the conveyor roller and the transparent plate. A guiding device which permits advance of the document from the document table to the transparent plate but hampers movement of the document from the transparent plate toward the document table and defects it upwardly, is provided between the document table and the conveyor roller. When the conveyor roller is rotated in the carrying direction, the document on the transparent plate is deflected upwardly by the guiding device and discharged through a discharge opening formed in the opening-closing frame.
