ABSTRACT:
Modular automatic paper handling apparatus wherein a vertically movable paper item tray is incrementally elevatable into a paper feeding position adjacent a feeding device. A cable drive including an electromagnetic impulse clutch and solenoid escapement provide control for elevating the item tray. A pivotally movable reload tray is adapted to be positioned over the main item tray such that finger-like projections integral therewith are interfitted with upstanding projections on the main item tray enabling the main item tray to be raised into a position to automatically unload paper from the reload tray after which the reload tray is automatically snapped out of the way of the main item tray. A cable counter weight permits the main tray to retract downwardly to feeding position without overrunning or bouncing.
