Definitions

  • the invention relates to a color device and an ink ribbon cassette.
  • the inking device is to be used in particular in a printer with a print head which is normally arranged to be movable parallel to a printing base in the line direction, but should be arranged fixed in the printer frame.
  • the ribbon cassette should in particular be designed so that, as is known, it consists of two parts. It is important for the design of the cassette that it can be used unchanged for different printing widths. It is also essential, however, that the cassette holds the ink ribbon in such a way that it can be inserted into the printing device and brought into an operational state without the fingers being soiled.
  • the cassette contains an endless ribbon. It consists of two parts, the actual cassette, which contains all functional elements, such as the spooled ribbon and a re-inking device for this, and a cassette cover, which closes the cassette for shipping.
  • the actual cassette which contains all functional elements, such as the spooled ribbon and a re-inking device for this
  • a cassette cover which closes the cassette for shipping.
  • the device has the disadvantage that it is hardly possible to use a new ribbon without bringing the fingers into contact with the ribbon. On the one hand, this has to do with the fact that the color tape must be securely slipped over the two fixed left guide rollers before the actual cartridge housing can be snapped into its right position after pulling out the ribbon. But this is also related to the fact that threading the ink ribbon into the guide devices of the print head is inevitable.
  • the invention relates to an ink ribbon cassette and, in general, to a color device which allows optimum handling, in particular such a device in which the ink ribbon cassette does not have, as is customary in many cases nowadays is connected to the movable print head, but in which the ribbon cassette is installed in the fixed printer frame.
  • This is also important, since in the case of a print head which is movable in the line direction and which also carries the ink ribbon device, the weight is increased by 30-40% compared to the weight of the print head alone. This is because it is not only necessary to then also move the ink ribbon cassette with the printhead, but also the drive means required for driving the ink ribbon in the form of a motor and a corresponding gear.
  • the invention has for its object to provide an ink ribbon cassette and a color device as a whole, which are preferably arranged in a fixed printer frame, and which are such that the insertion of the ribbon is possible without risk of soiling the hands of the operator is and without special handles are required to use the ribbon in guide devices either in front of the print head or for attaching the cartridge parts.
  • Another task is to create an ink ribbon cassette which, by its shape, automatically specifies the space within which the print head can move in front of the printing pad without requiring special guide means for the ink ribbon at the printing point.
  • An additional object of the cassette according to the invention is that the cassette can also be used with a fixed printing unit due to a slight modification.
  • the invention is based on a color device for a printer with a printhead which is normally movable parallel to a printing pad in the line direction and a printhead which is arranged in the printer frame and consists of two parts Ribbon cassette and is characterized in that a slide guide for the cassette extends over the entire width of the printing pad in the printer frame, and that guide parts corresponding to the slide guide are arranged on the bottom of the cassette, that the two cassette parts are detachably inserted into one another for shipping, in an exploded manner, operational states, however, are kept apart by cooperating locking means arranged in the printer frame.
  • each cassette part consists of a functional space, which receives essential functional elements and on which the guide parts are provided for cooperation with the sliding guide, and a guide space or part , which leads the ink ribbon to the level of the printing pad, the print head moving in the space between the functional spaces of the two cassette parts and the printing pad and between the guide spaces or parts.
  • the functional space of one part of the cassette for receiving the ribbon in the form of loose loops is designed as an endless ribbon, while the functional space of the other part of the cassette accommodates the re-inking device for the endless ribbon.
  • the ribbon cassette can be designed to reduce the space requirement so that the functional space of the second cassette part is designed to be considerably narrower than the functional space of the first cassette part and only contains guide elements for guiding and deflecting the endless ribbon, without the re-inking device. In the remaining space between the functional rooms and the printing pad on the one hand and the two guide parts of the cassette on the other hand, there is enough space to accommodate a standing printing unit. This would be the reason for this type of cassette
  • the cassette can also be connected to the movable print head.
  • FIGS. 1 and 2 were split over two sheets, which should therefore be considered side by side.
  • a printing pad 3 in the form of a roller or in the form of a pressure bar with a convex surface is arranged.
  • a guide axis 4 is fastened between the plates 1 and 2 and serves as a sliding guide for the print head 5.
  • this print head is a needle print head in which the needle guide head 6 can be recognized.
  • the printing needles of the print head 5 work together with a form web 7 which is guided around the printing pad 3.
  • the print head 5 can be relative to its guide axis 4 parallel to the printing pad 3 in the line direction by appropriate drive means be moved away, whereby the pressure takes place at the same time.
  • a slide guide 9 for the ribbon cassette 10 is fastened between the boards 1 and 2.
  • the slide guide 9 consists of a guide rail 8 which is provided with two guide strips 11 and 12.
  • the guide bar 11 can be seen as a simple, raised edge, while the guide bar 12 is angled twice, as can be seen in particular from the side view according to FIG. 3.
  • the guide bar 11 cooperates with a guide groove 13 on the bottom of the right cassette part 14 by guiding this cassette part.
  • the groove 13 is delimited by two projections 15, 15 'on the bottom of the cassette 10.
  • the cassette 10 has a further projection 16 bent at right angles, with which it can slide in the guide bar 12 bent twice at right angles and is guided in the process.
  • the groove 13 and the projection 16 are the guide parts of the cassette 10.
  • the locking of the right part of the cassette 14 in the right end position according to FIG. 2b serves on the one hand a stop pin 17 which cooperates with a projection 18 on the bottom of the cassette and on the other hand a locking means 19 in the form of a locking spring.
  • the spring 19 is fastened to the guide rail 8 and engages with one end in a recess 60 in the rail 8. As can be seen at 21, it is bent at right angles, so that it serves as a counter-stop for the stop 17.
  • the cassette 10 can be seen as consisting of two cassette parts 20 and 14, each cassette part having a relatively large functional space 22 and 23, as can be seen in FIGS. 2a and 2b, and one except for Height of the printing pad 3 advanced guide space or part 24 and 25.
  • the left cassette part 20 is provided with a latching surface 28, with which the cassette interacts with a latching pawl 29.
  • the pawl 29 is pivoted against the force of a spring 30 when the cassette is inserted, then snaps back under spring force and clearly defines the left part 20 of the cassette.
  • the projection 16 on the right part of the cassette 14 has been inserted into the guide bar 12 and at the same time the guide bar 11 has been inserted into the guide groove 15 on the bottom of the right part of the cassette 14. If the cassette has been inserted as shown in FIG. 1, the right part of the cassette can be seen 14 to the right, as can be seen in FIG. 2b, until it has reached its right end position shown here and is locked in this right end position.
  • the functional space 22 of the left cassette part 20 is the storage space for the endless ribbon 31 lying in loose loops and contains the drive means for the ribbon, consisting of a drive roller 32 and an elastically pressed counter pressure roller 33.
  • the counter pressure roller 33 is mounted on a lever 34 and is held elastically in contact with the drive roller 32 by a spring 35.
  • the ink ribbon 31 enters the guide space 24 of the left cassette part 20 through an opening 36, is guided around a guide roller 37 and then moved by the drive roller 32.
  • the drive roller 32 is driven via its hub 38 and a groove 39 provided therein.
  • the pin 40 of a coupling part 41 engages in the groove 39.
  • the coupling part 41 carries a gear 42, which in turn is in engagement with a gear 43.
  • the gear 43 is driven by a motor 44.
  • the functional space 23 of the right part of the cassette 14 contains two Ink rollers 45 and 46 and two ink transfer rollers 47 and 48.
  • the ink transfer rollers 47 and 48 are mounted on levers 49 and 50, which are under the influence of springs 51.
  • the springs 51 hold the ink transfer rollers 47 and 48 in engagement with the ink re-inking rollers 45 and 46.
  • the ink transfer rollers 47 and 48 also serve as guide and deflection rollers for the ink ribbon 31, which enters the functional space 23 of the right cartridge part 14 through an opening 52, is deflected by the two ink transfer rollers 47 and 48 in order to then leave the guide space 25 of the right-hand cassette part 14 again through an opening 53.
  • a spring 54 ensures that the ink ribbon 31 cannot twist in the outlet slot 53.
  • a guide device 55 provides for the production of the so-called Möbius loop for the endless ink ribbon 31.
  • the arrows indicate the transport direction of the ink ribbon 31.
  • the only drive element for the ink ribbon is thus the drive roller 32, which on the one hand causes the "stuffing" of the ink ribbon into the storage space 22, and on the other hand the ink ribbon on the way between the outlet slot 53 from the right cassette part 14 along the printing pad 3 through the insertion slot 36 and causes the guide space 24 of the left part of the cassette.
  • the tongues 56 and 57 on the right cassette part 14 engage in corresponding recesses 58 and 59 of the left cassette part 20, so that the ink ribbon is only exposed on the way between the left guide space 24 and the right guide space 25.
  • FIG. 5 shows yet another variation of the ribbon cassette according to the invention. It can be seen that without the re-dyeing device in the functional space 23, this space is considerably narrower than the functional space 22 of the left half of the cassette 20. This results in a spatially compact design of the entire cassette, but without the re-coloring device. If only a slight reduction in the size of the cassette is sufficient, then only one roller can be used instead of two re-inking rollers.
  • the essentially the same cassette can also be accommodated in a much smaller space and can therefore also be used with recording media 7 which have a substantially reduced width.
