Abstract
An ink ribbon cassette is provided for feeding and driving an ink ribbon in a printer or the like. The cassette includes a housing, a take-up core rotatably supported in the housing with the front end of the ink ribbon being coupled thereto and a take-off core rotatably supported in the housing. An ink spool is wound up on the take-off core, where the ink spool includes an outer periphery. A brake assembly is provided and includes a conical plate where the outer periphery of the ink spool rests on the conical plate, thereby decreasing the braking torque as the spool diameter decreases.
