ABSTRACT:
A document feeding apparatus has a deck that is placed at an angle such that the incline of the deck is sufficiently large so as to overcome the friction of documents placed thereupon. The deck has an opening at the bottom thereof through which a vacuum type conveyor extends to engage the bottommost document of the stack of documents to transport the bottommost document generally upwardly. With this feeding of the bottommost document the balance of the documents will remain in position due to the effect of gravity whereas the next-to-bottom sheet will be released from the bottommost sheet since the angle of incline is sufficiently great to overcome the frictional forces acting between these two documents.
