Abstract
A sheet-feeding apparatus comprises sheet-feeding rollers for advancing sheets, one at a time, from a stack of sheet material. The sheet-feeding rollers are supported by a drive shaft which is mounted for movement toward and away from the sheet stack so that the feed rollers may be selectively displaced from the stack, for example, to effect sheet replenishment. A cam surface associated with a slidable stack support cooperates with a cam-follower associated with the roller shaft to effect displacement of the feed rollers from the stack during sliding movement of the stack support. A pair of one-way clutches and a rack and pinion arrangement cooperate to allow the sheet-feed rollers to rotate freely during initial contact with the top sheet in the stack, thereby avoiding premature feeding of such sheet during a stack reloading process.
