Definitions

  • the invention relates to a ribbon cassette with reloadable ribbon spools of the type specified in the preamble of claim 1.
  • a removable cassette for a carbon band in a printer with a rotatable drive element for feeding the band has become known, the cassette consisting of a housing and a take-up reel for the tape.
  • a swiveling feed roller interacts with a spiked wheel with a take-up spool arranged on a fixed axis in order to wind up the carbon strip.
  • the feed roller with the spike wheel must first be disengaged from the take-up spool. In this changing process, several manual operations are required, since the feed roller must also be brought back into engagement with the take-up reel after the insertion of a new cassette into the take-up device of the machine.
  • DE-PS 25 53 329 shows an ink ribbon cassette for a typewriter or office machine of a similar type, in which the feed roller with the sprocket wheel is arranged in the cassette.
  • the feed roller remains in constant engagement with the carbon tape of the take-up spool.
  • This makes it possible to replace ribbon cartridges with only one hand.
  • This known ribbon cassette is very expensive, since the drive elements contained in the ribbon cassette for the carbon ribbon are thrown away after their consumption. Since the feed roller is also always in engagement with the take-up spool and the drive elements are mounted on the one hand in the base part and on the other hand in the cover firmly connected to the base part, it is not possible to replace the feed and take-up spools.
  • the invention has for its object to provide a ribbon cassette with reloadable ribbon spools, which allows easy replacement of the ribbon spools by means of a hinged lid, in which the opening in the bottom part is sealed by the lid.
  • the lid should in particular be easy to manufacture and without tight tolerances. This object is achieved by the invention characterized in claim 1.
  • the cover which is partially retractable on the base part, has in particular in the area of the ribbon inlet and outlet openings the ribbon cassette no longer protruding edges, the z. B. cannot be completely avoided by fault. This ensures that the cassette is sealed more tightly even when the lid is not completely level. Likewise, there is no risk of injury when changing the ribbon cassette due to protruding edges.
  • FIG. 1 shows a reloadable ink ribbon cassette 1, which consists of a cup-shaped base part 2 and a cover 4 which can be closed by its opening 3.
  • the cover 4 is in this case articulated to a side wall 5 of the base part 2 via joints 6, 7 and can be firmly connected to the base part 2 by means of a locking lever 8.
  • This locking lever 8 is pivotally mounted about an axis 9 on the side wall 10 opposite the side wall 10 of the base part 2 and has a latching lug 11 which can be latched behind a latching edge 13 of the cover 4 in the arrow direction 12 after the pivoting of the locking lever 8.
  • the cover 4 has a depression 14 corresponding to the thickness of the locking lever 8 in order to ensure a flat surface on the cover 4 for stacking a plurality of cassettes 1 on top of one another.
  • a supply spool 15 is rotatably mounted about an axis 16, from which an ink ribbon 17 can be unwound and through an outlet opening 18 can be led out of the cassette 1.
  • the ink ribbon 17 is fed via an inlet opening 19 to a take-up spool 21 which is rotatably mounted about a bearing axis 20.
  • the winding reel 21 is driven in a known manner via a sprocket wheel, not shown, which is in constant engagement with the winding of the winding reel 21 by means of a spring.
  • the outlet opening 18 and the inlet opening 19 are located in arm-like projections 22 and 23, which are designed as ribbon guide arms.
  • the base part 2 and the cover 4 are designed such that the cover 4 is in the closed state at least in the area of the two arm-like projections 22, 23 between the edges 24, 25, 26 of the base part 2, so that it can be lowered.
  • the base part 2 has contact surfaces 27, 28, 29, 30, 31, 32, 33, 34 for the cover 4, which are offset from the edges 24, 25, 26 by at least the thickness of the cover 4.
  • the cover 4 lies directly on the side opposite the arm-like projections 22, 23 on the edge 37 of the base part 2.
  • the cover 4 it is of course also possible to arrange the cover 4 recessed in this area.
  • the peripheral edge 25 of the base part 2 has a recess 35 for a gripping surface 36 arranged on the lid 4.
  • This gripping surface 36 is opposite the edge 25 of the bottom part 2 is formed above. This makes it easy to grip the lid for pivoting, the gripping surface 36 being protruding from the edge 25 of the base part 2.
  • the ribbon cassette 1 according to the invention enables simple and safe handling for changing the ribbon spools.
  • the joint 7 according to FIG. 1 is shown in detail in FIGS. 2 and 3.
  • the joint 6 is constructed accordingly.
  • Two resilient legs 38, 39 are integrally formed on the base part 2, between which there is a bearing recess 40 for a bearing journal 41 on the cover 4.
  • the bearing pins 41 are pushed through an opening 43 between the legs 38, 39, whereby these legs 38, 39 are pushed back and spring back into the bearing recesses 40 after the bearing pins 41 have engaged.
  • the threading of the bearing pins 41 into the bearing recesses 40 is facilitated by bevels 44, 45 on the legs 38, 39 in such a way that the oval-shaped bearing pins 41 can be pressed into the bearing recesses 40 with both the narrow and the wide surface, see FIG. 3
  • This ensures that the assembly of the cover 4 is possible both in the vertical position and in the horizontal position. This also ensures automatic production.
