ABSTRACT:
A cartridge for a typewriter typing ribbon comprises a container for accommodating the typing ribbon which can be of correctable or non-correctable type. A corrector cartridge can be removably fixed on the lower part of the container by engagement means. The corrector cartridge accommodates a correction ribbon which can be of the lift-off type suitable for the typing ribbon of correctable type, or of the cover-up correction type which is suitable for the typing ribbon of non-correctable type. Coupling means on the cartridge and the corrector cartridge permit the engagement means removably to fix the corrector cartridge to the container only when the caartridge houses the typing ribbon of correctable type and the corrector cartridge houses the correction ribbon of lift-off type or alternatively when the typing ribbon is of non-correctable type and the correction ribbon is of the cover-up type. In the event of a different choice, the coupling means prevent the engagement means from operating when the ribbons are not compatible with each other. Fixing means removably fix the container to a support of the typewriter either by itself or with the corrector cartridge attached and the fixing means do not cooperate and interfere with the engagement means and the coupling means.
