Abstract: A ribbon loading system for a printer utilizes a ribbon cartridge that includes a container enclosing two coaxially arranged ribbon reels. By providing flexible blades in the floor of the container, the reels are urged toward a top cover where relative movement is restrained. Upon loading of the cartridge, camming arms enter apertures in the container and are moveable to a clamping position to draw the blades from the ribbon reels and allow free rotational movement.For a presently preferred implementation, the structure including the camming arms is coupled through linkages to clear the ribbon threading path and thereby facilitate ribbon insertion.

Abstract: A duplicating arrangement which includes a copying machine for copying an original and an offset printing machine operatively connected to the copying machine for producing prints from a master copy. The copying machine and the offset printing machine are both constructed so as to be independently functional modules with an automatic control device being provided for controlling the operation of the copying machine and offset printing machines such that, depending upon the duplications to be made, the duplicating arrangement feeds a copy from the copying machine to either a depository or the offset printing machine, wherein the copy so-forwarded serves as a master copy in the offset printing machine.
