無端状搬送ベルトを所定回転駆動する駆動手段を
設けたことを特徴とする自動原稿送り装置。[Claims for Utility Model Registration] An endless conveyor belt wound around a driving roll and a driven roll is placed on a platen glass, and the document to be copied is transferred to the platen glass by the frictional force between the conveyor belt and the endless conveyor belt. In an automatic document feeder of a copying machine that transports a document to a predetermined exposure position above and discharges the document from a platen glass after exposure, the document that is carried into the automatic document feeder at a predetermined timing is held on the endless conveyor belt. A hole is provided in a portion of the endless conveyor belt that is covered by the leading edge of the document, and whether or not there is a document conveyed through the hole to a predetermined exposure position on the downstream side in the document feeding direction inside the endless conveyor belt. The present invention is characterized by further comprising: a document detecting means for detecting this, and a driving means for driving the endless conveyor belt to a predetermined rotation when the document detecting means detects that the document has not been conveyed to a predetermined exposure position. Automatic document feeder.
