ABSTRACT:
An ink ribbon cassette and a recording apparatus adapted to detachably attach the ink ribbon cassette thereto. An electrode for dissipating electrical charges on the ink ribbon surface is provided either in the ink ribbon cassette or on a carrier of the recording apparatus. The electrode can comprise a resilient conductive member, such as a ground plate having an end portion that is bent into a V-shape. In addition, the electrode may be provided with sharp projections adapted to make scratches on the ink ribbon surface. The electrode is adapted to be brought into contact with the ink ribbon surface either before or after the ink ribbon is used for thermal recording. The electrode forms a path through which charge on the ribbon can be dissipated even if the surface layer of the ribbon is an insulator.
