Abstract
An improved separator assembly for document feeders comprises a retarding roller and a cooperating opposed feed roller. The retarding roller is selectably rotatable into orientations such that the selected one of a plurality of different peripheral portions of the retarding roller will be oriented into operative position with respect to the feed roller. The retarding roller includes at least one cylindrical portion and another portion which has an interfering member projecting outwardly from the roller. Other surfaces of the retarding roller may comprise different materials in order to avoid scratches on the documents to be fed or to change the frictional force on the documents.
