Abstract
A moving bin sheet sorter has rotatable cams which engage portions of the sorter trays to move the trays at the ends adjacent to a sheet entry location between positions at which those tray ends are closely spaced above and below the sheet entry location and further spaced apart at the sheet entry location for receiving sheets supplied from a copier or printer. The cams are driven by an electric motor which is controlled to operate at a low speed as the trays are initially engaged and disengaged from the cam and a high speed during the major movement of the trays, thereby reducing noise resulting from high speed impact and shock loading of the cams and cooperative portions of the trays, as well as reducing noise resulting from high speed impact of said cooperative portions of the trays in guides for the trays.
