Definitions

  • the invention relates to a method for printing magnetically readable characters, the use of a matrix needle printhead suitable for this purpose and its production, the printing method being based on transferring magnetically readable ink in a printing unit from a single-use ink ribbon to a recording medium.
  • the magnetically readable fonts CMC 7 and E13B are important. Both fonts are currently carried out with type printing units, ie with full-contour characters (as is usual with typewriters). Foil made of plastic with a coating of a wax-like, colored and interspersed with magnetic particles is used as the ribbon.
  • type plate printers like type lever printers, are very large and the service life of the type plates is approximately 60,000 characters, i.e. 60 typewriter pages limited because the individual types are made of plastic and are actuated by means of a steel hammer and are therefore subject to considerable wear.
  • the invention is therefore based on the object of proposing a faster printing process for magnetically readable fonts (such as, for example, CMC 7 and E13B) with characters that can nevertheless be read satisfactorily, with the additional aspect that the method also provides advantages for the type of device.
  • magnetically readable fonts such as, for example, CMC 7 and E13B
  • the object is achieved according to the invention in that, in the basic form, vertical, bar-shaped printing areas are transferred to the recording medium, which are assembled into a character on the principle of a matrix, and in that the respective printing elements with the bar-shaped printing areas consist of one or more columns of printing elements each bar-shaped printing surface are controlled that the record carrier and Single-use ink ribbon are either stationary and a matrix needle print head is moved, the single-use ink ribbon being fed during printing breaks or the recording medium and the single-use ink ribbon being moved and the matrix needle print head being held stationary.
  • This makes it possible to write magnetically readable fonts much faster, including the fonts CMC 7 and E13B.
  • Significantly smaller printing units can be used for this, which saves costs.
  • Such printing units achieve printing speeds of several hundred characters per second.
  • the use of a single-use ink ribbon must be taken into account by controlling the ink ribbon appropriately when printing.
  • the recording medium and the single-use ink ribbon can first be stationary and the matrix needle printhead is moved and the ink ribbon is fed during printing breaks or the recording medium and the single-use ink ribbon are moved and the matrix needle printhead stands still.
  • a relative movement between the recording medium and the ink ribbon is advantageously avoided during printing.
  • the wax-like layer of the ink ribbon is transferred to the recording medium (eg paper) by heat or shock by the print head. At the point at which a line character is transferred from the single-use ink ribbon to the recording medium, the wax layer on the single-use ink ribbon is completely missing after the transfer.
  • control can also take place in such a way that, when the print head and the stationary recording medium are moved, the single-use ink ribbon is moved in sections together with the print head.
  • a simple method of transporting the single-use ink ribbon is that the single-use ink ribbon is moved by the length of the line section to be printed during a print-free back-fitting movement of the matrix needle printhead in the beginning of line position against the advance movement during printing.
  • a better utilization of the single-use ink ribbon is possible by the following control: It is proposed that the single-use ink ribbon be moved within two pauses between two characters in the same direction as the matrix needle printhead, namely by the length between two adjacent characters. Of course, the disposable ink ribbon is not transported while characters are being printed. The used distance of the single-use ink ribbon is transported immediately before the next line is printed, so that a section of unprinted ink ribbon is available for the area to be printed before printing a line.
  • a matrix needle print head for printing magnetically readable MICR characters, in which magnetically readable color can be transferred from a single-use ink ribbon to a recording medium, serves as the basis for fast printing.
  • the magnetic legibility of the characters is only achieved if the tips of the printing needles have a bar-shaped printing surface that is perpendicular to the width of the recording medium.
  • the magnetically readable characters can be written in an advantageous manner only with such printing needles or heat-transferring contact elements.
  • the width of the vertical, bar-shaped printing surface is 0.08 to 0.19 mm.
  • a method for producing a matrix needle printhead for printing magnetically readable characters with printing needles guided in a front housing in a guide plate and with electromagnetic coil drives arranged in a rear housing and intermediate layers which can be inserted between the front and rear housings, permits a particularly advantageous design of the required matrix needle printhead .
  • This goal is achieved in that the intermediate layers provided with a recess for the printing needle group are removed, then the printing needles are ground at their tips in the installed state in the form of a vertical printing surface in a wedge-shaped or stamp-like manner and after that the intermediate layers are reinserted.
  • the individual characters are composed of bar sections 10, all of which run in parallel in order to generate corresponding signals when reading, i.e. to be able to generate when scanning.
  • the characters are acc. Fig.2 designed.
  • the magnetically readable font E13B is also described in the ISO 1004-1977 standard.
  • the font is acc.
  • Fig.1 contrasted a CMC 7 font produced on the basis of the invention in the matrix printing process, with practically no deviations being recognizable, with the difference that the characters according to. Fig.3 have been written much faster.
  • the font E13B is drawn on an enlarged scale with reference to Fig. 4, so that the matrix printing process becomes clear and vertical, bar-shaped printing areas 11 can be recognized individually and it also becomes clear how a character is composed, i.e. is formed.
  • 16 to 19 show a matrix needle print head 12 for printing magnetically readable MICR characters (see FIGS. 1 to 4), in which magnetically readable color can be transferred from a single-use ink ribbon 13 to a recording medium 14.
  • a front housing 6 which is spaced apart by spacers 5 from a rear housing 7, 14 printing needles 15 are guided in a guide plate.
  • the rear housing 7 there are electromagnetic coil drives 16, each of which is assigned to a printing needle 15 and a printing needle 15 drive.
  • an armature 17 is pushed forwards against the force of a return spring 18 by the electromagnetic coil drive 16 and later moved back into the drawn rest position shown by the force of the return spring 18.
  • the printing needles 15 have at their tips 19 a bar-shaped printing surface 1 (FIG. 5) or 2 (FIG. 6) that is perpendicular with respect to the width direction of the recording medium.
  • the width "a" of these vertical printing surfaces 1 and 2 is practically 0.08 to 0.19 mm.
  • Figures 7 to 9 show a printing needle group 20 consisting of a printing needle column 21 (Fig.7) or two printing needle columns 21 (Fig.8).
  • the printing needles 15 in Fig.5 are provided with a concave transition 22 and the printing needles 15 in Fig.6 with a wedge-shaped transition 22.
  • Fig. 7 the bar-shaped pressure surfaces 1, which are perpendicular in their basic form, are shown hatched and in Fig. 9 as well, whereby Fig. 7 shows the pressure surface 1 due to the concave transition 22 and Fig. 9 due to the wedge-shaped transition 22 the pressure surfaces 2.
  • Fig.11 shows the used ink ribbon 13 with the magnetic ink transferred to the recording medium 14, the ink ribbon movement direction 24 pointing to the left and the printing unit or printhead movement direction 25 (Fig.12) to the right.
  • FIG. 13 shows the interaction between the pressure on the ink ribbon 13 and the pressure on the recording medium 14 in the case of an ink ribbon movement direction 26 opposite to the printing direction 27.
  • Fig.14 is an enlarged section of the ribbon 13 after printing the characters acc. Fig.12 shown, the individual printed, used characters in the ribbon 13 are close together, so that the ribbon 13 is fully used.
  • the ink ribbon 13 was transported in sections between the printing of adjacent characters in the printing unit or printhead movement direction 25.
  • Figures 18 and 19 now show the method for producing a matrix needle printhead 12.
  • the intermediate layers 5 are provided with a recess 29 for the needle group 20.
  • the intermediate layers 5 are removed and the front housing 6 and the rear housing 7 are connected and then, in the position of Fig. 18, printing needles 15 can be wedge-shaped or stamp-like as described be ground.
  • the intermediate layers 5 are then reinserted, after which the position of the printing needles 15 according to Fig. 19 is created.
  • the method can also be used if a plurality of pressure needle gaps 21 are present in different guide plates 3 and 4 which can be moved up and down in parallel (cf. Figures 5 and 6).
