Abstract
A sheet feed device for sequentially selecting and feeding sheets of paper from one or more trays or magazines mounted upon a printer and delivering them to the platen of the printer. The device includes one or more selector latch mechanisms, one associated with each tray, whose movement is controlled by the platen rotation and which, in turn, controls the rotation of sheet feed rollers associated with the trays, in response to a specific sequence of forward and reverse angular platen movements.
