Definitions

  • the invention relates to an ink ribbon cassette for printers, in particular for matrix printers, with bearing pins fastened to the ink ribbon housing and arranged on the broad sides of the exchangeable ink ribbon housing.
  • the ribbon cassette housings contain endless ribbons that are driven by an externally connectable drive by means of pairs of rollers arranged inside.
  • the ribbon exits a housing protrusion through a housing exit nearby at one end of the platen, is passed through the reciprocating printhead along a platen and runs through a housing input near the other end on the platen into an opposite housing protrusion.
  • the endless ribbon is circulated in this way.
  • the ribbon housing is interchangeable and rests in bearings that are open at the top.
  • a known solution which relates to a multicolored ink ribbon, has such a device.
  • the ribbon housing is pivotally held in bearings of the printer frame by means of an aligned pair of pins, so that the adjacent traces of the individual colors of the multicolor ink ribbon can be moved up and down by a nodding movement of the ribbon housing in front of the printing point of the platen.
  • This pitching movement is controlled by a curve a cam cam generated, which is driven by an electric rotary motor.
  • the known solution is limited to multi-colored ribbons.
  • a redesigned ribbon housing must therefore be created for monochrome ribbons, so that two different ribbon housings are required. This is time-consuming, time-consuming and therefore costly to manufacture the ribbon cassettes.
  • the system with two different ribbon housings increases, for example, the storage and thus the storage costs.
  • the invention is therefore based on the object of proposing a single ribbon housing which is suitable for both single-color and multicolor ribbons. For this reason, only a uniform ribbon housing should be equipped with different ribbons during the production of the ribbon housing.
  • the ribbon housing for single-color ribbons and for multicolor ribbons is uniformly provided with two pairs of bearing journals and that a flat support projection is provided opposite each other on the broad sides of the ribbon housing for cam curves.
  • This system requires only a single injection tool in the production of the ribbon housing.
  • the ribbon housings produced in the injection mold are filled either with a single-color ribbon or with a multicolor ribbon.
  • the printer When installing the ribbon cassette, the printer itself can be equipped for a single-color or a multi-color system. In both cases the ribbon housing is the same or already prepared for the respective application.
  • the corresponding components on the printer are also easy to convert in production and assembly. Instead of a cam cam control, only a second bearing is provided, which allows a rigid arrangement of the ribbon housing.
  • the ribbon device uses an ink ribbon cassette (1) with a central part (2) and broad sides (3 and 4) arranged on the left and right, which enclose a free space (5) in which the carriage (not shown) with a print head of a printer moves.
  • the broad side (3) ends with a housing outlet (6) from which a single-color ribbon (7) or a multicolor ribbon (8) emerges and through a housing entrance (9) back into the other broad side (4), so that the ribbon is guided in a circle.
  • the drive of the respective ribbon consists of pairs of rollers arranged inside the ribbon housing (10), which are automatically coupled to a drive when the ribbon housing is inserted into the printer.
  • the ribbon housing (10) is uniformly provided for all ribbons with a first pair of bearing pins (11a, 11b) and at a certain distance with a second pair of bearing pins (12a and 12b). Then a flat support projection (13a and 13b) is injection molded onto the broad sides (3 and 4).
  • the ribbon housing (10) according to FIGS. 1 and 2 is already filled either with a single-color ribbon (7) or with a multicolor ribbon (8) after production and closed as usual with a lid.
  • the ribbon housing (10) is supported with the flat support projection (13b or 13a) on this cam curve (17), so that when the ribbon housing (10) rotates in the direction of the arrow (19) one of the ribbon tracks of different colors corresponding to that described Pitching movements is set.
