Abstract
A document feeding apparatus wherein documents are fed one by one from a document stacker by a first document feeding device and a second document feeding device which is provided in the midway of a path from the first document feeding device to a processing unit, and the movement of the document is stopped temporarily by a document stopping device before the leading end of the document fed from the second document feeding device reaches a synchronous sensor provided in the midway of a path from the second document feeding device to the processing unit. The first document feeding device consists of a feeding belt connected to a drive source through an electromagnetic clutch, and a separating roller which is in sliding contact with an upper surface of the feeding belt in a non-rotary state. The second document feeding device consists of a drive roller connected to a drive source through an electromagnetic clutch, and a driven roller which is press contact with the drive roller.
