Abstract
In a document feeding apparatus, a first motor which drives a transporting mechanism provided at downstream side in the document transporting direction of a pair of timing rollers and a clutch connected with the pair of rollers are firstly energized, and the energized first motor drives the transport mechanism and the pair of timing rollers in the document transporting direction. A second motor which drives a paper feeding mechanism and is provided at upstream side in the document transporting direction of the pair of timing rollers drives the paper feeding mechanism after it is energized for a predetermined period of time to transport two sheets of originals placed and in contact with the pair of timing rollers from its downstream and upstream sides onto a platen glass. A sensor which detects the rear edge of an original being discharged from the platen glass is prohibited from detecting the rear edge of an original firstly discharged.
