SHEET FEEDING APPARATUS Abstract of the Invention A paper feeder for use in dispensing paper into a printer with sensors for leading and trailing edges of paper and with a platen which rotates in a forward imprinting direction in response to a leading edge and in a backward, paper-ejecting direction in response to a trailing edge, the paper feeder comprising a paper holder, at least one rotatable drive roller to operably contact paperin the holder, and a drive train connecting the platen to the roller and controlled exclusively by such connection to cause no roller rotation in response to forward platen rotation, and to cause roller rotation in a paper-dispensing direction in response to backward platen rotation; the drive train is arranged so that the roller delivers paper to a paper-loading position on the printer not before the platen completes paper ejection; whereby backwards platen rotation provides simultaneous paper ejection and dispensing.
