。[Scope of Claim for Utility Model Registration] In an automatic document feeder that conveys a document to the top surface of a contact glass of an image forming apparatus, there is provided a roller that temporarily stops the document by bringing the leading edge of the document fed from the paper feed section into contact with a nip point. , a pair of bearings that support the rotating shaft of the roller, and a spring latch that is provided on the rotating shaft of the roller and transmits or disconnects drive to the rotating shaft, at least one of the bearings and the rotating shaft. A one-way clutch is interposed between the transmission gear, which is a part of the spring clutch, and the rotating shaft to prevent the rotating shaft from rotating in the opposite direction to the direction in which the document is conveyed. Features an automatic document feeder.
