Abstract
In combination with paper conveying apparatus in an electrostatic copier, including a movable photoconductor adapted to be electrically energized from a source of supply of electrostatic charge for attaching thereto a sheet of paper for movement therewith, there is described structure for detaching the sheet from the moving photoconductor. The structure includes the provision of one or more apertures in the photoconductor and finger means movable at least partially through the apertures, as the photoconductor is moving, for urging a portion of the attached sheet of paper away from the photoconductor. In addition, the structure preferably includes vacuum header means for urging the remainder of the attached sheet of paper away from the moving photoconductor.
