ABSTRACT:
A sheet stacker or sorter for a xerographic or other copier has respectively one or more upwardly-inclined or vertical sheet receiving bins fed from below by nip rolls located at the exit of a pair of guide plates which direct the sheet towards the bin. The trail edge of the sheet is lifted from the exit of the guide plates onto a ledge of the bin by a scoop differentially pivoted at the end of a drive arm and a slave arm, the slave arm being limited in its pivotal excursion by pins journalled on the drive arm. With this mechanism a scoop is tipped forward when it enters the bin first depositing the sheet and then the rear wall of the scoop urges the trailing portion of the sheet into conformity against the support face of the bin for improved stacking.
