Abstract

1439771 Electro-photographic apparatus XEROX CORP 17 Aug 1973 [30 Aug 1972] 39013/73 Heading G2H [Also in Division H1] Toothed wheel 33 rotates in dependence on the movement of endless photo-conductive belt 12 and produces a succession of pulses by interaction of its teeth 34 with magnetic pick-up 35 as they pass it. The pulses are counted, starting from a datum when the leading edge of a copy sheet is released by fingers 45, and the exposure lamps L, development apparatus 17 and heat-fixing means 24 are actuated in accordance with the count. Five or more sequences of actions may be maintained simultaneously, associated with successive exposed lengths of the belt 12.
