Abstract: In ribbon cartridges (10) including a ribbon take-up spool (20) which is peripherally driven by a spacially fixed driving roller (18), it is necessary for the take-up spool (20) to move away from the driving roller (18), as the ribbon (22) accumulates on the spool (20), while remaining in proper driving engagement with the roller (18). According to the invention, this is achieved by a frangible member (24) which resists the movement of the take-up spool axle (28) except when caused by ribbon accumulation. Frangible member (24) may either be formed as an integral part of the cartridge walls or be bonded thereto. Member (24) will break or tear as axle (28) is forced away from roller (18) by the increasing diameter of take-up spool (20).
