ABSTRACT:
An improved sheet feeding mechanism for an automatically driven typewriter. The feeder mechanism includes a housing which is mounted on the typewriter and defines a supply magazine for storing a stack of sheets to be typed and a finish magazine for storing typewritten sheets. When it is desired to feed a sheet through the platen of the typewriter, a platen clutch is disengaged to disconnect the platen from the typing mechanism and connect the platen to a feed roll. A pressure plate is actuated to force the pack of sheets in the supply magazine against the feed roll, and the feed roll will scrub the outermost sheet from the pack and move the sheet downwardly through a tapered chute and around the platen. After passing around the platen, the leading edge of the sheet actuates a sensing mechanism to release the pressure plate and engage the platen clutch to thereby begin the automatic typing on the sheet. When the typing is completed, the platen clutch will be disengaged and the sheet is driven upwardly to the finish magazine, and when the trailing edge of the sheet passes the sensing mechanism the pressure plate will be actuated to feed a second sheet to the platen.
