Abstract
Device for detaching a copy sheet from the photoconductive drum of an electrophotographic copying machine, wherein the drum has a radial protuberance to which the leading edge of the copy sheet is held by electrostatic attraction and wherein a pick off finger is fixedly mounted adjacent the periphery of the drum at such a distance from the periphery to engage the drum, during its rotation, only in correspondence with the protuberance, so as to detach the copy sheet from the drum.
Claims5
Device for detaching a copy sheet held by electrostatic attraction to the photoconductive element carried by the drum of an electrophotographic copying machine comprising:
- means defining a radial protuberance in the periphery of the drum between its surface and said element in the zone in which the leading edge of the copy sheet contacts the element,
- a pick off finger fixedly mounted adjacent the drum at such a distance as to engage said element only in correspondence with said protuberance, whereby during the rotation of the drum the pick off finger engages the leading edge of the copy sheet and detaches it from the element.
