Abstract
In a sheet handling system with a supporting frame, a sheets compiling tray, and a sheets ejection system including an drive shaft with plural sheet drive rollers and a pivotal mounting system for pivoting the drive shaft between a first position for sheets ejection and a raised second position, the pivotal mounting system provides vertical freedom of movement of at least one end of the shaft in the first position to provide a self-leveling more uniform sheet engagement force, yet also provides a positive accurately centered constrained position of the shaft in the second position. The illustrated pivotal mounting system includes a pivot pin vertically movable within a mounting slot in the supporting frame in the first position and spaced apart limited length mounting slots providing end stops engaging mounting pins in the second position to automatically center the pivot pin.
