ABSTRACT:
A ribbon cartridge has openings through its lower casing in order to selectively receive an electric conduction type ribbon end sensor or a photoelectric type ribbon end sensor on a printer. Ribbon housed in the ribbon cartridge extends across one of the openings which is separated from the other by a webbing. Where the sensor is of the electric conduction type, the webbing ensures the location of its electrodes to the back of the ribbon which carries a conductive member on its back. The ribbon is provided with, in addition to a transparent tape section at its tail end, a thin piece which is connected by means of an adhesive to the ribbon adjacent to the tail end. An upper casing is formed with a window to facilitate visual checks on a remaining length of the ribbon. An area of the inner surface of the lower casing which corresponds to the window is painted in a color different from that of the ribbon, thereby promoting quicker and more accurate checks on the remaining length.
