Claims

[Scope of claim for utility model registration] (1) Multiple sheets of originals set on a document table are fed while being sandwiched between a pick-up roller and a pressure plate, and the fed documents are separated one by one by a feed roller and a separation roller and then fed. In the automatic document feeder, the pressure plate that presses the document against the pick-up roller includes a rigid member that is rotatably supported and urged to rotate in one direction by a spring member, and the rigid member. 1. An automatic document feeder comprising an elastic member having one end fixed to the elastic member and the other end pressing the document. (2) In an automatic document feeder that feeds a plurality of originals set on a document table while sandwiching them between a pick-up roller and a pressure plate, and separates and feeds the sent originals one by one using a feed roller and a separation roller, A pressure plate that presses the document against the pick-up roller is rotatably supported on a shaft and is biased by a spring member to rotate in one direction; a first rigid member that presses the document; and a second rigid member that presses the document. An automatic document feeder characterized in that the parts are connected to each other by an elastic member.
