A sheet feed device, which is suitable for attachement to a printer or the like comprises a cartridge (10) for holding a stack of sheets (5), and a separator feed mechanism (50). Mechanism (50) comprises shingler wheel (52) mounted on pivotable arm (56), and conical feed rollers (70, 72). In operation, wheel (52) first cooperate with the uppermost sheet of stack (5), causing its leading edge to travel ramped sidewall (16) to edge aligner (20). Sensing means detect the presence of the sheet against aligner (20) and control rotation of arm (56) and disengagement of wheel (52) from the uppermost sheet which is then free to be driven in the feed direction by feed rollers (70, 72). |
