A document feeding apparatus includes a driven roller and a feed roller rotatable with a drive shaft, an idle roller gearing with the driven roller and a document feeder. The document feeder includes a pick-up roller having a shaft portion, a cam slipping into the shaft portion and a driven gear gearing with the idle roller, a protrusion disposed on the shaft portion, one end of the cam being a spiral shape defining an end thereof, and another end defining a first engaging portion and a second engaging portion thereof, a lump disposed at a lateral of the driven gear. The feeding apparatus keeps in separation of the document from a next feed-in document and prevents the documents from overlapping.
