ABSTRACT:
A disk-type sheet inverting and stacking system in which a rotatable disk unit includes a receiving slot for having the lead edge of a sheet substrate inserted therein such that rotational movement of the disk unit inverts the sheet and delivers it to a stacking tray. The disk-type inverting and stacking system also includes a passive sheet registration system for restraining movement of a sheet positioned in the receiving slot by providing a reciprocating boss member in a retaining cavity on the disk unit, such that the reciprocating member can be shifted, under the influence of gravity, from a non-operative position extending into the slot with a sheet positioned therein, for applying a normal force against the sheet in response to rotational movement of the disk unit.
