SHEET REGISTRATION MECHANISM ABSTRACT OF THE DISCLOSURE A registration mechanism for feeding sheets seriatim including a plurality of continuously driven roller sets located along a sheet feed path. A first roller set receives the sheets seriatim and moves the sheets toward a second roller set. The second roller set includes a pair of axially spaced,continuously driven rollers mounted on a drive shaft and a pair of thrust washers which sandwich a registration disc therebetween, the disc being freely mounted on the roller drive shaft. The registration disc has a registration finger which selectively extends through the sheet feed path. When the finger is positioned to extend through the feed path, it is latched to prevent rotation of the disc and provide registration of the sheets fed by the first roller set against the finger. At predetermined time intervals, the finger is unlatched and due to the action of the thrust washers on the disc, the disc is rotated with the driven rollers to move the finger out of the sheet feed path to enable the sheet to be fed by the rollers in registration to a downstream processing station. -1-
