ABSTRACT:
An ink ribbon cassette for use in an office machine comprises: an inking roll impregnated with ink; a ribbon-drive roll for driving an ink ribbon; and a ribbon-driven roll driven by the ink ribbon. The ink is transferred from the inking roll to the ink ribbon through any one of the ribbon-drive and said ribbon-driven roll, which one is pressed against the inking roll so as to be brought into a slidable contact with the same. In the ink ribbon cassette, the improvement resides in that: the ink ribbon cassette further comprises a spring. The spring has its contact portion brought into a resilient contact with an outer peripheral surface of the inking roll so as to urge the same against any one of the ribbon-drive and the ribbon-driven roll, so that the ink impregnated in the inking roll is constantly supplied to the ink ribbon in printing.
