Abstract
A document feeding route is provided in an automatic document feeder, and a feeder cover is provided on an upper portion of the automatic feeder and arranged to open and close an upstream half route of the document feeding route by being movable in a pivoting fashion. A plurality of pairs of drive rollers and idler rollers are provided in a downstream half route to feed a document toward a document ejection port. A jam clearance mechanism arranged to move the idler rollers or the drive rollers in a direction toward releasing a nipped state is arranged to face the downstream half route. The jam clearance mechanism includes a pair of cam frames and releasing bodies. The cam frames undergo a sliding displacement in a direction along which the pairs of idler rollers and drive rollers are arranged in coordination with opening and closing of the feeder cover. The releasing bodies move back and forth in coordination with the sliding movement of the cam frames.
