Abstract: The present invention relates to an ink jet cartridge, in particular for supplying ink to an ink jet head of a recording apparatus, such as a printer or the like, said cartridge being characterised in that it contains at least two vacuum producing materials of different vacuum producing capacities while the higher density cellular material serves to meter the flow of ink there is another lower density cellular material disposed upstream of the denser material to provide a sufficient ink storage capacity.

Abstract: The present invention relates to a ribbon cartridge comprising a housing with an upper and a lower half, a ribbon received in said housing, a driving means comprising two driving gears for driving said ribbon, said driving gears rotatably supported in the housing and in engagement with each other for transporting the ribbon inbetween the driving gears. Specifically, the housing is provided with a bearing means for supporting a first one of said driving gears at a circumferential surface thereof in the middle of the height of said driving gear, so as to allow self-alignment of the driving gears with each other by adjustment movements other than a rotation around the axis of rotation.
