Definitions

  • the invention relates to an arrangement on a tape cassette for relieving the force on the take-up reel provided with a slip clutch, in which the ink or thermal ribbon is guided from a supply reel via deflection rollers past a printhead to the take-up reel.
  • Ribbon and thermal print cartridges generally have a supply spool and a take-up spool for the ribbon.
  • Several deflection rollers serve to guide the belt.
  • Various possibilities are known for this (DE-38 08 603 A1, DE-38 00 113 A1, EP-0 189 984 B1) to hold the band under appropriate pretension and to prevent sagging.
  • a belt drive for winding continuously exerts a force on the belt. This can lead to the fact that even if the paper to be printed is not in contact with the tape or is in contact with the tape but is not moved, an additional tape feed occurs due to high tensile forces through the take-up reel.
  • the object of the invention was to ensure that the winding is decoupled from the forces that can be achieved by friction between the ribbon and the paper, both when the take-up train is switched on permanently and when required.
  • the cassette 1 for ink or thermal ribbons 2 encloses a supply reel 3 and a take-up reel 4.
  • a plurality of deflection rollers 5 serve to guide the tape.
  • the tape 2 is guided from the supply reel 3 to the take-up reel 4 via the print head 6.
  • a meandering tape guide 7 is additionally provided between the deflection rollers 5 arranged after the print head 6 and in front of the take-up reel 4.
  • This meandering band guide 7 consists of several staggered rollers. An arrangement of three rollers has proven to be expedient.
  • the meandering tape guide 7 relieves the load on the take-up spool 4, since an increased frictional force is achieved due to the wrap angle of the tape 2 on the tape guide 7. Thus, the tensile force can vary to a considerable extent without the tape 2 being pulled off the supply reel 3 in the idle state. Only when the wrap angle is reduced by the feed of the tape 2 through the friction between tape 2 and paper 8, a tape transport takes place.
