Patent number: 4231652Abstract: A drum for an electrophotographic copier with the drum serving as an image support and being connected to a rotary drive of the copier, the drum including a stock roll for accommodating a supply of a photosensitive weblike semiconductor material and an empty or takeup roll for receiving the weblike semiconductor material. The semiconductor material is guided over the outer peripheral surface of the drum from the stock roll and is taken up by the empty roll by means of a preferably stepwise adjustable drive. The drum including the stock roll, takeup roll, and semiconductor material form an exchangeable unit adapted to be inserted as a whole into the electrophotographic copier. The drum includes a slit defined by two deflector rolls from which slit the semiconductor material is adapted to be led into and out of the interior of the drum.Type: GrantFiled: November 24, 1978Date of Patent: November 4, 1980Assignee: Develop KG Dr. Eisbein & Co.Inventors: Kurt Moser, Helmut Wegmann
