ABSTRACT:
An ink ribbon cartridge for use in an office machine includes a housing; a ribbon; a supply reel for storing unused ribbon wound thereon and a take-up reel for storing used ribbon wound thereon, a drive roller rotatably supported in the housing; and an arrangement for resiliently urging the drive roller and the ribbon wound on the take-up reel into a peripheral, torque-transmitting contact with one another. The drive roller is arranged for being drivingly engaged by an advancing mechanism of the office machine when the cartridge is in place, whereby the drive roller imparts a rotation to the take-up reel in a winding direction for pulling the ribbon off the supply reel, for moving the ribbon through a printing station of the office machine and for winding the ribbon on the take-reel. There is further provided a reverse winding arrangement for pulling ribbon off the take-up reel and for winding the ribbon on the supply reel. The reverse winding arrangement includes a device for permitting the application of a winding torque to the supply reel; and a device for preventing blockage of the take-up reel by the drive roller in a direction opposite the winding direction.
