Abstract
In an automatic document feeder for use in combination with an electrophotographic copying machine for feeding documents successively into the copying machine by separating and feeding the documents one by one from a stack of documents, the stacked documents are placed on a document table and are fed by a pair of rollers into a nip portion between a rotating separation roller and a separation plate having a rubber sheet applied thereto to separate and feed documents one by one from the lowermost one, and an edge detecting sensor for detecting a front edge of a document is arranged downstream with respect to the separation roller to produce an edge detection signal. When the edge detection signal is produced, the relevant document is once stopped at the front edge detecting sensor and after a start signal for denoting the completion of a copying operation for the preceding document is supplied from the copying machine, the relevant document standing by the front edge detecting sensor is advanced. An opening for manually inserting a document is provided at a downstream position with respect to the front edge detecting sensor and a rotatable lid is provided above the opening.
