Abstract
An adaptation of an inked ribbon cassette to printers of higher printing speed is achieved where a supply spool is used as inked ribbon storage. Furthermore, the problem of an environmentally proper disposal of used inked ribbon cassettes is solved. At least two rotary drivable spool axles (3, 4) are spaced apart from each other on a base plate (1), open toward the upper side and open on the bottom side, where the spool axles (3, 4) are rotary supported on the base plate (1). The inked ribbon reels (2, 5) can be individually attached onto the spool axles (3, 4). A first inked ribbon guide element (7) is coordinated to one spool axle (3, 4). The inked ribbon (6) is guided from a first inked ribbon reel (2) along the first inked ribbon guide element (7) and parallel to the print path (17) and back via a second inked ribbon guide element (8) onto the second inked ribbon reel (5). In each case, a controllable electrical drive motor (9 ) is disposed on each spool axle (3, 4) at the bottom side (1a) of the base plate (1).
