ABSTRACT:
A cartridge for an ink or carbon ribbon of an office machine comprises a container of parallelepipedal form in which a pair of spools are rotatable for the ink or carbon ribbon. A part of the ink or carbon ribbon extends through one aperture to the exterior of the container and returns to the interior through another aperture. Two arms are associated with the two apertures and project from the exterior of the container. The arms support the portion of the ink or carbon ribbon exterior of the container, away from the container, when the container is removed from the machine and makes the insertion of the ink or carbon ribbon arms in a lift ribbon guide upon mounting of the container on the same machine. The container is further provided with a window disposed over the periphery of one of the two spools for manually rewinding the ink or carbon ribbon on the spool after the container is mounted on the machine.
