Abstract (en)
An apparatus for driving a ribbon cassette (1) for a printer, which ribbon cassette includes a supply spool (11) and a take-up spool (7) between which an inked ribbon (20) extends, comprises a motor (2) for driving a driving shaft (4). The driving shaft can be directly coupled to the take-up spool of the ribbon cassette. A detector provides a signal to a processing unit in response to the ribbon transport, which processing unit can operate the motor for transporting a length of the ribbon as determined by a printed character. A ribbon cassette to be used at a printer with such an apparatus, comprises a cassette casing (18) with an output (21) and a feed opening (22), a supply (11) spool with a ribbon supply and a take-up (7) spool for the used ribbon. The inked ribbon is directly led from the supply spool through the output and feed openings to the take-up spool. Both spools each are provided with a hollow spool hub (6, 10) which is accessible to and can be coupled with a driving shaft (4) and a detection shaft (8), respectively, through an opening formed in the bottom wall (24) of the cassette casing.
