ABSTRACT:
A ribbon cassette has an ink ribbon; a case; a cover coupled to the case by hinge pins, the cover being freely opened or closed through hinge pins; a drive roller in contact with the ink ribbon for running the ink ribbon; a follower roller for pressing the ink ribbon against the drive roller a holder for holding the follower roller; and a spring for biasing the follower roller against the drive roller via the holder. The holder is further provided with hook parts, and the cover has protruding pieces which engage with the hook parts of the holder and thereby move the holder away from the drive roller to detach the follower roller from the drive roller.
