ABSTRACT:
Disclosed is a cartridge and a cartridge assembly for a typewriter, the assembly comprising a pair of case members, each case member having a separate chamber and including means for releasably connecting the two case members in superimposed overlapping relation. First and second pairs of spaced apart ribbon guide means are associated with each of the case members and dimensioned to be aligned, first pair to second pair. Each of the case members includes a separate supply and take-up spool, the supply spool having a fixed axis of rotation and the take-up spool having a shiftable axis of rotation along a translatory path. An opening is provided along one edge of each of the case members, the openings being aligned in the paths while the take-up spools are biased in their respective paths towards the opening. Also disclosed is a drive mechanism for the cartridge in which the type of ribbon (for example, carbon or cloth) is indicated on the cartridge by a cam arrangement and, upon insertion into the machine, automatically selects the correct feed and ribbon lift mechanism to minimize ribbon wastage.
