Ink-ribbon cartridges, which can be operated with one hand, for typewriters or similar office machines have stationarily mounted drive rollers (5) with pin wheels which are always kept securely in engagement with coils of winding-on reels (4). These winding-on reels (4) which can be moved away from the pin wheels with an increasing coil diameter are mounted rotatably on swivel levers (8). In order to guarantee proper winding of the ink ribbon (2) onto the winding-on reel (4) and thus also complete unwinding of the supply reel (3), the bearing of the swivel lever (8) in the cartridge (1) must be designed without play. The invention is based on the object of providing an inexpensive bearing without play for the swivel lever (8) in the cartridge housing (1). This is guaranteed by the fact that the bearing pin (7) is arranged fixedly on the swivel lever (8), and that the housing (19) has a bearing (11) with a triangular bearing opening (12) for the bearing pin, which bearing opening has three side walls (13, 14, 15) which are arranged at an angle to one another, are connected to one another via roundings (16, 17, 18) and have slight elasticity. In an advantageous design, the diameter of the bearing pin (7) is slightly larger than the diameter of a circle enclosed by the side walls (13, 14, 15). The described bearing of the swivel lever (8) affords advantages not only in terms of production, but also in terms of handling. <IMAGE>
