Abstract
A curved blade overlays the marginal portion of a photocopier drum photosensitive surface at the transfer station to engage copy sheets and direct them to a transport assembly removing the sheets from the transfer station. The blade is pivotally mounted at one end and connected to a reciprocating actuator at the other end. It is pivoted away from its overlaying position, after the transport assembly engages the leading corner of the sheet so that the sheet can then contact the marginal portion, and back to its overlaying position after the trailing edge of the sheet has left the surface of the drum. In one embodiment the actuator is mechanically responsive to the photocopier scanner. In another embodiment, the blade is pivotable about an intermediate portion, and the actuator is operated by a solenoid energizable by a switch at the appropriate times.
