Abstract

A sheet sorting apparatus for collating and distributing sheets received from a reproducing apparatus and adapted to reduce static charge from the sheets includes an array of sheet receiving bins defined by tray members. A transport means conveys sheets past each of the bins. Each bin has at its opening an electrically insulting diverter member that can be pivoted from an inoperative to an operative position to deflect and guide a sheet into the associated bin. Attached to the diverter member is an electrically conductive brush arranged to contact a sheet entering the bin and an electrically conductive track connecting the brush via conductive bearings to the grounded conductive frame of the sorter.
