Sheet feeding apparatus with lateral registration.

摘要

Sheet feeding apparatus including feed rollers (41, 42) for feeding sheets (50) in a process direction and registration means (52, 53) for registering each sheet in a direction laterally of the process direction. The registration means comprises shifting means (53) for laterally shifting a carriage (52) on which the feed rollers are mounted. A sensor (57) is arranged to provide a signal on detecting the presence of a sheet, and control means controls the lateral shifting means in response to the signal. The control means is arranged such that if the sheet (50) is not detected by the sensor (57) on initial entry of the sheet into the feed rollers the shifting means (53) is activated to move the feed rollers laterally towards the sensor until the sheet is detected by the sensor whereupon said lateral movement is stopped, or if the sheet is detected on initial entry of the sheet into the feeding means the shifting means is first activated to move the feed rollers laterally away from the sensor until the sensor no longer detects the sheet and is then activated to move the feed rollers back towards the sensor until the sheet is agian detected by the sensor. <IMAGE>
