ABSTRACT:
An arrangement for supplying originals for a copying apparatus has a supply stack arranged above an illumination location of a copying apparatus, guiding members forming a transport path for guiding the original from the stack to the illumination location, a transporting device arranged to turn the original removed from the stack and supply the original to the illumination location, wherein the transporting device includes a rotatable transport cylinder connected with the transport path and having a peripheral portion with a turnable suction nozzle member with a plurality of suction nozzles forming the separating device, the stack has a stack-supporting surface with an end section forming a tangent with the periphery of the transport cylinder and having an opening extending from a contact point with the cylinder and to a front stack abutment, and a control device is provided and arranged to switch off the transport cylinder in a position in which the suction nozzle member is located in the region of the opening of the stack-supporting surface, to turn the suction nozzle member to the lower side of the stack, to activate a valve communicating the suction nozzles with a suction conduit of a suction source, to again switch on the transport cylinder, and to turn back the suction nozzle member on the periphery of the transport cylinder.
