Sheet feeding and aligning apparatus.

摘要

Sheet feed and aligning apparatus receives sheets fed in skewed orientation from a stack (18). A roller pair (46) initially advances the sheets without altering the skew angle, to further roller pairs (48, 56). As these pairs advance the sheet, sensors (68 and a further one, not shown) positioned along a line at an angle to the direction of sheet feed, sense its leading edge. In accordance with the timing of this sensing, drive means (42,46) for the further roller pairs are independently controlled to correct the skew.
