ABSTRACT:
A sheet stacker, e.g. for a photocopier, providing accurate trail edge registration includes co-acting driven output rollers associated with a sheet guide for directing sheets in an upwardly inclined direction. An output tray for receiving sheets exiting the output rollers has a support face inclined upwardly in the direction of sheet travel at an angle greater than that imparted to the approaching sheets such that the leading edges of the sheet contact the support face before the trail edges exit the output rollers. The output tray also includes a base edge support which, in the plane of the support face, is inclined downwardly and comprises at the lower end a corner registration stop. A fulcrum is provided at the upper end of the base edge support and is arranged such that after exiting the output rollers the sheets slide under their own weight, trail edge first, down the support face and abut the fulcrum intermediate their edges remote from the registration corner stop and the center of the sheets. Thus the sheets rotate under their own weight about the fulcrum until their trail edges abut the base edge support, the inclination of which is such that the sheets slide on their trail edges down the support until they abut the corner registration stop.
