Abstract
A document feeding mechanism includes a frame, a document picking means positioned in the frame for picking up and conveying a document, a stopper means positioned in the frame for blocking the conveyance of the document, a supporting portion cooperating with the stopper means for supporting the document picking up means while the document picking up means is raised at a predetermined level, and a blocking portion restricting a rotatable angle of the stopper means for blocking the conveyance of the document while the document picking up means is raised at the predetermined level. The document feeding means is kept at the predetermined level via the cooperation of the supporting portion and the stopper means for supporting the document feeding means. Since, the document feeding mechanism has high reliability to resist shake and crash for preventing the document picking up means from being drooped.
