Abstract: A sheet feeding apparatus comprises a loop transport belt defining numerous air passage holes, which are stretched and hung above the recording sheet so that an outer surface of the belt faces to a top surface of the recording sheet and driven to go around; a suction device that depressurizes and sucks air through the air passage holes of the transport belt, causing the recording sheet to adhere to the outer surface of the transport belt; and a corrugator that protrudes beneath the surface of the transport and pushes the recording sheet down, and retracts above the surface of the transport belt, and is installed beside and adjacent to the transport belt in a width direction of the recording sheet, wherein a position where the corrugator contacts with the recording sheet can move between a position where the corrugator protrudes and a position where the corrugator retracts.

Abstract: An apparatus for changing the direction of conveying paper in which paper is stopped by the operation of driving roller pairs in conjunction with idle roller pairs. The respective driving and idle roller pairs are urged against one another by the operation of a solenoid or the like. In order to move the paper, a clutch is engaged to rotatably operate the driving pairs.
