Abstract

PURPOSE: To prevent double-feeding to the transcription part by arranging a roller on the midway of the conveyance path in a paper feeding apparatus and arranging a blade which gets up aslant against the roller.
CONSTITUTION: When the uppermost layer sheet 3 and the second sheet 3' on the underside are superposed and drawn out at a same time from a paper feeding roller 7, the sheet 3' is retarded due to the contact friction with a blade 14, and only the sheet 3 advances and runs against the peripheral surface of a roller 13 and passes through a small slit t and sent into the transcription part 2 of a photosensitive drum 1, due to the revolution of the roller 13. The sheet 3' retarded can not resist the frictional force of the blade 14, and as the small slit t is blockaded by the sheet 3 advancing, further advance is impeded, and thus double-feeding of sheet to the transcription part 2 is prevented.
