Definitions

  • the invention relates to an ink ribbon cassette which can be placed on a typewriter or similar office machine and has a storage space for a supply reel and a take-up spool for an ink ribbon of the type specified in the preamble of patent claim 1.
  • the conventional ribbon cassettes that can be placed on a typewriter or similar office machine have a storage space for a supply reel and a take-up reel for an ink ribbon, the ink ribbon leading from the supply reel through two guide channels arranged at a distance from one another on the storage space through a printing station of the machine. and can be rewound onto the take-up reel.
  • the ribbons consist either of textile ribbons, which are transported several times past the printing station from one spool to the other, or of single carbon ribbons, which only run once through the machine, since each surface part of these ribbons can only be used once for printing.
  • the ribbons can consist of multi-carbon ribbons, which also run through the machine only once, but in which individual surface sections provide a repeated impression.
  • the size of the feed step is not important in the case of textile ink ribbons, since each surface section of the ribbon is used several times. In the case of single carbon ribbons, the feed step must be an entire character width, while in the case of multi-carbon ribbons a drive device for the ink ribbon which generates a lower step feed is required for their economical use.
  • the invention has for its object to provide an ink ribbon cassette that enables a compact structure for all types of ribbons and that can be easily placed on and removed from the receiving device in the machine with one hand, without a certain dexterity from the person operating the machine is required.
  • the ink ribbon cassette should be designed so that in the case of typewriters with a correction device, the correction tape can be arranged directly under the ink ribbon in the cassette.
  • the stroke of the correction tape from the rest position to the impression position should be as short as possible.
  • the ribbon cassette according to the invention is very compact and saves material. Due to the advantageous embodiment of the subject of the invention according to claims 2 and 3, the correction tape can be arranged directly under the ink ribbon, which results in a very small stroke of the correction tape from the rest to the impression position. The correction tape can therefore be moved very quickly from the rest position into the impression position with a small force and then also very quickly reset.
  • the further embodiment of the subject matter of claim 4 enables the guide channels to have only a height that is only slightly larger than the width of the ribbon.
  • the subject matter of patent claim 6 ensures that the ink ribbon cassettes with ink ribbons, for which a different step feed is required, can be compactly trained.
  • FIG. 1 shows a top view
  • FIG. 2 shows a side view of an ink ribbon cassette 1.
  • the ribbon cassette 1 consists of a trough-shaped base part 33 and a cover 35 which can be connected to it.
  • the cover 35 has holes 36 which are evenly distributed in order to reduce weight and noise.
  • the cover 35 has bearing journals, not shown, in corresponding bearing bores in the base plate 33 can be plugged and locked.
  • the bottom part 33 of the ribbon cassette 1 has on its rear wall 38 protruding bearing lugs 8, 10 which can be plugged into correspondingly designed bearing recesses 40, 42 of a receiving plate 2 of the receiving device for the ribbon cassette in the machine.
  • the bottom part 33 has on its side walls 44 and 46 locking pins 12, 14 which cooperate with the locking lever mounted in this mounting plate 2 for locking the ink ribbon cassette on the mounting plate 2.
  • the tabs 8, 10 are first inserted into the corresponding bearing recesses 40, 42, then the cartridge is pivoted against the mounting plate 2 until the trunnions 12, 14 by the locking lever in the mounting plate 2 be locked.
  • the assembly of the ribbon cassette 1 can therefore be carried out with one hand.
  • the trough-shaped bottom part 33 has a storage space 5 for a supply 3 and a take-up reel 41 for an ink ribbon 11.
  • the supply reel 3 is rotatably mounted in the bottom surface 30 of the storage room 5 (FIG. 9), the ink ribbon 11 from the supply reel 3 via deflection guides 13, 15, 17 and 19, which are arranged on the bottom surface 13 in the storage room 5, as a Guide arm trained guide channel 23 is guided.
  • the ink ribbon is then passed through the printing station via a deflection guide 21 arranged in an outlet opening 69 of the guide channel 23 and then via a deflection guide 25 in an inlet opening 71 of a guide channel 24 designed as a guide arm.
  • the ink ribbon 11 is guided to a winding drive 31 via deflection guides 27, 29.
  • the deflection guides 27 and 29 are also arranged on the bottom surface 30 of the bearing space 5.
  • the two guide channels 23, 24 are firmly connected to the base part 33, a type carrier 73 being rotatably mounted between their (23, 24) free ends by means of a stepping motor, not shown.
  • the type support 73 has resilient tines, at the free ends of which the types are arranged in a known manner.
  • the type set in each case is struck against a recording medium 79 by a print hammer 75 driven by a magnet 77, an impression being produced in a known manner with the interposition of the ink ribbon 11.
  • the winding drive 31 has a toothed drive wheel 39 which is constantly in engagement with the outermost turn of the winding spool 41.
  • the take-up spool 41 is rotatably mounted on a pivot lever 45 (43), the pivot lever 45 being pivotable about an axis 49 and being acted upon in a clockwise direction by a spring 47 such that the outermost turn of the take-up spool 41 is always held in engagement with the drive gear 39 becomes.
  • the drive wheel 39 can be coupled to a drive element 61 which can be driven by a motor 59 via a change-speed gear designed as a step-size changeover device.
  • the change gear has interchangeable gear pairs 63, 65 which can be selected to produce a step feed of the ribbon 11 which is different depending on the type of ribbon and which can also be used immediately before or during the insertion of the supply 3 and the take-up reel 41 into the storage space 5.
  • the gear 63 of the change gear is firmly connected to the drive wheel 39, while the other gear 65 can be coupled to the drive element 61 of the machine and is firmly connected to a handwheel 67. This hand setting wheel 67 can be rotated in the cover 35 from outside the housing by means of a finger.
  • the supply spool 3 is firmly connected to a toothed brake disk 81.
  • this brake disk 81 On its outer circumference, this brake disk 81 has a toothing 83 into which an arm 15 of a resilient round wire 85 firmly clamped on one side engages.
  • the ink ribbon 11 coming from the supply reel 3 is continued via the deflection guide 13 around the arm 15 and then via the deflection guides 17, 19, 21 in the manner described above. If the ink ribbon 11 is driven in the direction of arrow 89 by the winding drive 31, the arm 15 is lifted out of the toothing 83 of the brake disk 81, whereby the supply reel 3 is released.
  • the floors 26, 28 of the two guide channels 23, 24 have an offset 16, 18 relative to the floor 30 of the storage space 5 in such a way that below the guide channels 23, 24 in continuation of the floor 30 of the storage room 5 there is a free space 50, 52 for in
  • the receiving device of the ribbon cassette 1 machine parts arranged in the machine arises and that the unwindable from the supply reel 3 ribbon 11 is guided at a close distance above the inner bottom surface 26 of the guide channel 23 with the outlet opening 69.
  • the machine parts are individual parts, e.g. B.
  • the bottoms 26, 28 of the two guide channels 23, 24 each have an outwardly facing, partially cylindrical indentation 20, 22 for the winding surfaces 60, 62 of the supply 56 and the take-up reel 58 for the correction tape 54.
  • the supply reel 56 and the take-up reel 58 for the correction tape 54 are rotatably mounted, for example, in the receiving plate 2, the correction tape 54 being guided from the supply reel 56 via a deflection guide 64 through the printing station and via a further deflection guide 66 to the take-up reel 58.
  • the winding reel 58 is driven in a known manner and is not closer shown.
  • the correction tape 54 is arranged directly under the ink ribbon 11. This enables a small stroke for lifting the correction tape from the rest to the working position.
  • the color and the correction device form a compact device on the receiving plate 2. Since the designed as a brake disk 81 flange of the supply reel 3, designed as a holding device position levers 45 for the take-up reel 41 and the exchangeable gear wheels 63, 65 in a relation to the inner bottom surfaces 26, 28 of the guide channels 23, 24 deeper portion 32 of the storage room 5 are arranged movably, a compact arrangement of the ribbon cassette 1 is created.
