Definitions

  • the invention relates to an ink ribbon cassette for a typewriter or similar office machine of the type specified in the preamble of claim 1.
  • a sound jam occurs in the interior of the housing and thus an increase in the noise level.
  • the sound waves striking the housing or flat components from the inside stimulate the vibratable parts to vibrate, which in turn are the cause of the machine noise emitted to the outside.
  • the cup-shaped base part and cover plate are provided with holes. Through these holes, the noise build-up is reduced and the noise level inside the housing is reduced, but the abrasion caused by the guidance and the drive of the used carbon ribbon falls through the holes in the bottom of the base part and contaminates the machine parts underneath.
  • Such contamination is avoided in the ink ribbon cassette according to European published application 81 109 546.2 in that the soundproofing means of the base plate consist of depressions, the base of which is closed by a membrane.
  • the base has circumferential collars around the openings and additional contact surfaces for the winding of the supply and take-up spools.
  • the invention has for its object to provide an ink ribbon cassette, by which the noise accumulation in the interior of the housing is effectively reduced and by which the abrasion of the used ink ribbon from openings in the bottom part of the cassette housing is reliably avoided.
  • the cassette should be of a compact design and enable the supply reel and the take-up spool to be driven easily, the abrasion on the ink ribbon used being kept low.
  • an ink ribbon cassette 1 is arranged ready for operation on a receiving device 2 of a typewriter or similar office machine, which is arranged along a recording medium 3 is slidably arranged.
  • the record carrier 3 can be transported in a known manner via a paper roller 4.
  • the ribbon 6 emerging from an exit slot 5 of the ribbon cassette 1 is unwound from a supply spool 7 and passed between the recording medium 3 and a type carrier 11 via a tensioning lever 8 and ribbon guides 9, 10.
  • the type carrier 11 is, for. B. a type wheel with a plurality of radial slots, whereby elastic webs are formed, at the ends of which a type is arranged.
  • the setting of the type wheel 11 takes place via a stepping motor, not shown, which is also arranged on the holding device 2.
  • the printing of the characters takes place via a slide hammer mounted displaceably on the receiving device 2.
  • B. is driven by an electromagnet.
  • the ink ribbon 6 is guided via the guide 10 into an inlet slot 12 of the cassette housing consisting of a pot-shaped base part 13 and a cover 15 provided with openings 14. Then the ribbon 6, the z. B. consists of a carbon tape that can only be used once, passed via a barrel-shaped deflection roller 16 to a take-up spool 17.
  • This take-up reel 17 is rotatably supported by a hub 18 on a bearing pin 19 which is fixedly connected to a carrier plate 20.
  • This carrier plate 20 is slidably mounted on the bottom 22 of the base part 13 with a sliding surface 21, the sliding surface 21 having two spaced-apart guide pins 23, 24 for a longitudinal slot 25 penetrating the bottom 22.
  • the supply spool 7 is rotatably mounted on a bearing axis 26 arranged vertically on the base 22, to which an annular stiffening rib is concentrically aligned and 27 other stiffening ribs 28, 29 and 30 are aligned radially outside this stiffening rib.
  • the winding 31 is rotated on the rounded stiffening ribs 28, 29, 30 and the core of the take-up reel 7 on the annular stiffening rib 27 stored in cash.
  • the cover 15 has appropriately designed stiffening ribs 32, 33, 34 and 35, which also serve to support the winding 31.
  • the supply spool 7 has a hub 36, which is wrapped by a shaped wire designed as a clamping lever 8 with two free legs 37 and 38.
  • One leg 37 of this shaped wire is firmly anchored with the free end 39 in a recess 40 of the bottom part 13 of the cassette housing, while the other leg 38 is freely movable and has a rotatably mounted deflection roller 42 at its free end 41.
  • the movable leg 38 moves away from the fixed leg 37 of the shaped wire in such a way that the static friction between the shaped wire and the hub 36 of the supply reel 7 is eliminated.
  • This release of the supply spool 7 enables the ink ribbon 6 to be easily unwound from this supply spool 7. If the tension in the ink ribbon 6 subsides again, the movable leg 38 of the shaped wire swings back immediately into its starting position, whereby the supply reel 7 is braked again. Since rotation of the supply spool 7 is no longer possible, the ink ribbon 6 is always kept taut.
  • stiffening ribs 44, 45 and 46 In order to prevent ribbon abrasion from falling out of the longitudinal slot 25 of the base part 13 of the cassette housing, the latter is surrounded by raised stiffening ribs 44, 45 and 46.
  • a stiffening rib 44 and 45 is parallel to the direction of displacement of the rectangular-shaped door gerplatte 20 arranged on each side of the longitudinal slot 25.
  • the ends 47, 48, 49, 50 of these stiffening ribs 44 and 45 are firmly connected on the one hand to the annular stiffening rib 27 and on the other hand to a stiffening rib 46 arranged perpendicular to the direction of movement of the carrier plate 20.
  • the stiffening ribs 44, 45 arranged on the floor 22 on both sides of the longitudinal sides 51, 52 of the carrier plate 20 have mutually directed legs 53, 54 which reliably prevent the displaceable carrier plate 20 from tilting with the take-up reel 17, see FIG. 4.
  • the leg 53 has incidentally, at the same time, a support surface 55 for the winding 31 of the supply reel 7.
  • the base part 13, together with the stiffening ribs 28, 29, 30, has four support surfaces for the winding 31 which are offset by 90 °, thereby reliably preventing the individual layers of the winding 31 from shifting.
  • the bottom 22 in the bottom part 13 of the cassette housing has blind holes 56 for soundproofing, two openings 57 and 58 for latching locking elements in the receiving device in the machine and a further opening 59 for sensing elements for scanning the ribbon end.
  • the winding 61 of the take-up spool 17 can be supported in the bottom part on the stiffening rib 46 and on a bearing rib 60 extending from the other end of the carrier plate 20 and running in the direction of the bearing journal 19 such that the individual layers of the ink ribbon 6 do not oppose one another during winding move.
  • the bearing pin 19 for the take-up spool 17 is movably arranged with an extension 62 in a continuous longitudinal slot 63 of the cover 15 arranged in the direction of displacement of the carrier plate 20, as a result of which the ribbon supply is indicated.
  • the longitudinal slot 63 in the cover 15 has a circumferential collar 64 on the inside, which at the same time serves to support the winding 61 of the take-up reel 17.
  • the transport roller 65 has a spike wheel 66 which engages with the winding 61 of the winding spool 17, and is on one end 67 with a hollow pin 68 on a collar 70 surrounding an opening 69 in the base 22 and at the other end 71 with a bearing bore 73 arranged centrally in a handwheel 72 for a centering pin 74 on the inside 75 of the cover 15.
  • the end face 76 of the handwheel 72 on the transport roller 65 is provided with corrugations 77, a part of this end face 76 being arranged so as to protrude from a circular opening 78 in the cover 15. This makes it possible to rotate the transport roller 65 via the handwheel 72, which enables the ink ribbon 6 to be wound onto the take-up spool 17.
  • the opening 78 in the cover 15 is located in a circular recess 79 on the cover edge 80 such that the end face 76 of the handwheel 72 does not protrude from the remaining surface of the cover 15.
  • the stiffening rib 46 on the bottom 22 of the bottom part 13 is designed and arranged in such a way that the abrasion of the ink ribbon 6 which occurs when the sprocket 66 winds up cannot fall out of the openings 58, 59 and 25.
  • the opening 69 is shielded from abrasion by the collar 70.
  • the locking opening 57 in the bottom 22 of the bottom part 13 is shielded by a stiffening rib 81 which, on the one hand, is firmly connected to the stiffening rib 30 and, on the other hand, has an extension rib 82 arranged concentrically with the supply spool.
  • the resilient leg 38 is slidably mounted on this extension rib 82, as a result of which (38) is easily movable due to the low friction.
  • the carrier plate 20 is acted upon by a spring device in such a way that the winding 61 of the take-up spool 17 is always held in engagement with the sprocket wheel 66 of the transport roller 65.
  • This spring device consists of a leg spring 83 which is mounted on a pin 84 and has a fixedly arranged first leg 85 and a resilient second leg 86. The second leg 86 rests against a shoulder 87 on the bearing pin 19 for the take-up spool 17, see FIGS. 3 and 5.
