ABSTRACT:
Apparatus for automatically feeding individual sheets from a stack of individual sheets into a copy device provides for a guide plate and tray for holding a stack of individual sheets which are aligned and registered thereon by a movable stopper which engages the guide tray to enable such alignment. The stopper is hingably supported to allow for rotation thereof when moved out of engagement with the guide tray in order to prevent interference with the feeding of the individual sheets and damage thereto. Primary rollers are provided for feeding of individual sheets from the top of a stack of sheets and are supported above the stack of sheets for engagement and disengagement therewith to effect such feeding in coordination with movement of the stopper.
