Definitions

  • the invention relates to a printer and a color device therefor, in which the printing is carried out by means of an ink transfer ribbon on a normal recording medium and in which a stripper is connected to the print head, which causes the ink transfer ribbon to be detached from the recording medium after printing.
  • Ribbons that are suitable for one-time printing using ink transfer especially those that are suitable for thermal printers, have the peculiarity that they tend to adhere to the recording material.
  • the object of the invention is to arrange the print head and the scraper in relation to one another such that the ink ribbon can be inserted in a paper insertion position of the print head without a manual threading process.
  • the invention is accordingly characterized in that the print head is pivotally arranged between a defined working position and a defined paper insertion position and that the scraper is designed as an element which is supported on fixed parts in the vicinity of the printing substrate, so that it swivels when the print head is pivoted into the paper insertion position retains its functional position, so that when the paper is inserted, the stripper maintains its position between the recording medium and the ink ribbon, while the print head rests on the ink ribbon and the printing pad when it is pivoted into the working position.
  • the ink transfer belt is arranged in a cassette and passes through the printing zone in the tensioned state.
  • the device works most safely if the scraper is supported on a stationary part immediately in front of the printing pad.
  • the scraper is particularly effective when it is itself a resilient part. Should the pressure in two Directions occur, that is from left to right and from right to left, then it is useful to provide two wipers together with the printhead, one of which acts when the printhead runs clockwise, the other when it runs counterclockwise.
  • FIG. 1 reveals, the entire printing device is housed in a housing 1 which surrounds the printing device on all sides.
  • the housing 1 is provided with an opening 2 through which a guide table 3 for the recording media 36 to be inserted (FIG. 3) passes.

  • the drive rollers 15 and 16 are driven by a motor 17 (FIG. 2) via a gear 18 and a further gear 19.
  • the gear 19 drives the shaft 19 'on which the drive rollers 15 and 16 are attached.
  • the motor 17 can be driven in two directions so that it moves the recording medium 36 in both the feed and ejection directions.
  • FIG. 2 also shows the ink ribbon 20, which is provided as a thermal ink ribbon with three ink zones 21, 22 and 23, namely the ink zones yellow, magenta and cyan.
  • the print head 24 consists of the support member 25, the support member 26 and the actual thermal head 27 (FIG. 1, 3 and 4), which carries the thermal printing elements.
  • the supporting part 25 of the print head 24 is guided on the axis 28 so as to be displaceable in the line direction and is at the same time guided on a fixed bar 30 by means of projections 29.
  • the part 25 can thus only be moved transversely, but cannot be pivoted.
  • the part 26, however, is guided only on the axis 28 and is clockwise in FIG. 1 pivoted so that the thermal head 27 rests on the pressure bar 32 when it is moved from left to right for a print run.
  • a resilient wiper 33 is attached, which rests with its multiple resiliently bent nose 34 with its front end 35 on the guide plate 8 and, as in particular FIG. 3 recognize lets, rests between the ink ribbon 20 and the recording medium 36.
  • the stripper 33, 34, 35 is arranged as a spring clip in such a way that it rests resiliently against the upper paper guide, regardless of whether the print head 24 is in its printing position (working position) (FIG. 1) or in its raised position (paper insertion position) (FIG. 3).
  • FIG. 3 and 3a show that in the working position (FIG.
  • FIG. 3a reveals that when the print head 24 is pivoted in the paper insertion position, it is raised so far that the ink ribbon 20 is inserted in its cassette 5 without problems between the print head 24 and the wipers 34/35 resting resiliently on the pressure bar 32 and on the guide plate 8 can.
  • a pivot lever 37 is mounted on the back of the part 25, which is in its right one End position cooperates with a stop pin 38, the stop pin 38 pivoting the pivot lever 37.
  • the part 26 is pivoted relative to the part 25 and thus the two parts 26 and 27 are raised.
  • the pivot lever 37 interacts with a release pawl (not shown) which pivots it into its other end position, as a result of which the print head moves into its position shown in FIG. 1, 3 and 4 visible printing position is brought.
  • the drive of the print head 24 in the line direction, the drive of the ink ribbon 20 and the displacement of the ink ribbon cassette 5 serves a second motor 39, which drives a roller 42 via two gears 40 and 41, over which a drive belt 43 is stretched.
  • the drive belt 43 is wound around a roller 44.
  • the two ends of the roll are resiliently attached to the print head 24.
  • a clock disk 46 is also connected to the motor axis 45, by means of which the respective position of the print head 24 is reported to the electronic control.
  • the clock disk 46 works together with a light barrier, not shown.
  • the printhead 24 is reciprocated by reversing the rotational movement of the DC motor 39.
  • a mandrel 48 Via a reduction gear 47, which also contains a one-way clutch, a mandrel 48 is driven, which enters a recess 75 in the ink ribbon cassette 5 and thereby drives the ink ribbon 20 (FIG. 5).
  • the one-way clutch in the transmission 47 causes the ink ribbon to be driven only during the backward movement of the print head 24 when the parts 26 and 27 are in the inactive, raised position according to FIG. 3a are.
  • the cassette is inserted through the slot 4 in the housing, connected to its drive means (mandrel 48) and brought into latching engagement with the holding and shifting means.
  • the cassette At its right edge, the cassette has a recess 49 (FIG. 5) into which a guide bar 50 on the printer frame 51 engages.
