Definitions

  • Wire printer One form of mosaic printer apparatus is the so-called Wire printer.
  • the ends of the wires are pushed against a print medium so that characters are printed which are composed of dots.
  • higher printing speeds have been realized over conventional engraved type printers.
  • Wire printers usually involve complex mechanical structures both for the selection of the wires and the making of the mosaic impressions.
  • the operation of wire printers heretofore involved substantial noise which frequently proves an undesirable characteristic for commercial uti1ization.
  • the impression producing members i.e., the wires
  • the dot impressions on the print medium are produced by oscillating the dot-forming impression members while in contact with the print medium at frequencies above the audible range.
  • the mosaic data pattern is produced on a continuously moving print medium.
  • the printing unit comprises a plurality of dot-forming elements arranged in a row which oscillate when excited at their respective inherent frequencies.
  • the impression forming members are magnetic material adapted to be excited magnetically, prefer ably magnetostrictively, while they are in contact with the print medium.
  • magnetostrictive oscillators may be constructed which are virtually inertialess, very short effective times may be obtained, e.g., 0.5 millisecond.
  • the print elements are selected on the basis of inherent frequency above the audible range, a virtually noiseless printing apparatus may be obtained which is simultaneously simple in construction and inherently capable of high speed.
  • FIG. 1 is a schematic representation of a printing apparatus incorporating one type of arrangement for carrying out the practice of the present invention.
  • FIG. 2 is a perspective view of one form of printing unit incorporating the features of the present invention.
  • FIG. 3 is a perspective View of a second embodiment of the printing unit capable of printing in accordance with the principles of the present invention.
  • FIG. 4 illustrates a mosaic data pattern producible in accordance with the practice illustrated in the preceding figures.
  • FIG. 2 which comprises a body member 11 preferably made of ferrite material taking the form of a closed magnetic circuit wherein magnetostrictively oscillatable printing elements, such as rods or wires 12, are fastened to a support 13 at their nodal point. While various materials are available which are magnetostrictively oscillatable, one suitable material is an alloy comprising 49 parts of iron, 49 parts of cesium and 2 parts of vanadium which is known under the trade name Vaooilux or Permendur. A ferrite body member gives low magnetic resistance for flux return.
  • the wires 12 are bent at their nodal points and on the rear side thereof carrying exciting coils 14 which may be suitably connected in any well-known manner to suitable ultrasonic frequency generators.
  • Through holes 15 provided at the front side of the body member '11 the wires 12 protrude out of the body member 11 when energized, whereas, in their unexcited condition they are flush with the front surface 16.
  • Holes 17 in the rear Side of body member 11 are positioned to accommodate the remote ends of the wires 1-2, thereby forming a more efficient arrangement for providing a magnetic circuit for the oscillating magnetic flux.
  • the printing head 10 of FIG. 2 is shown in a printer apparatus in FIG. 1 which comprises a roller 18 which presses against the printing head 10 for obtaining a satisfactory impression on interposed print medium such as a continuous forms paper 19 and a marking medium such as carbon paper ribbon 20, respectively.
  • the print medium 19 moves from a supply reel 21 over idler Poll 22 past the printing head 10 and over a drive roll 23 to V a container 24 in any well-known manner.
  • a pressure roll 25 is provided between the printing head 10 and the print medium paper 19.
  • the carbon paper 20 is drawn from supply reel 26 to a takeup reel 27.
  • Means for causing the movement of the print medium and the marking medium may take various forms and are not shown in order to simplify the description.
  • printing comprises the information of alphabetical and/or numerical characters by composition of dots divisible into lines and columns similar to television thereby forming a mosaic pattern.
  • a character may be subdivided, for example, into a 5-by-7-dot matrix so that as shown in FIG. 4, five printing elements (e.g., d1 to d5) are needed for one character.
  • the number of printing elements arranged side by side determines the number of characters that may be printed in one line, for example, the length of a line.
  • These printing elements may be arranged so as to be mounted on a single body member 11 extending across the entire length of the print medium.
  • a plurality of individual printing heads 10 of the type shown in FIG. 2 may be arranged along a print line so that multiple printing operations can also be formed simultaneously (i.e., in parallel) in plural columnar positions.
  • an L is printed as follows as shown in FIG. 4: printing clement d1 is pressed six times in an uninterrupted sequence (corresponding to the last six lines of the ink spots) onto the printing paper moving as indicated by arrow 28. Thereafter, printing elements d1 to rid are depressed simultaneously corresponding to the first line of the ink spots. Where panallel printing is being effected, all other characters of the same line are printed at the same time as the L. If it is intended to apply the ink spots of the characters column by column, the paper 19 is not fed vertically from top to bottom, but from seft to right. In that case, the printing head must be, in the example chosen, provided with seven printing elements. If a plurality of printing heads it are provided, it is possible to print several lines simultaneously starting from the left and going to the right.
  • FIG. 3 Another embodiment of the printing device is shown in FIG. 3 wherein the printing heads ill are replaced with printing elements formed as sheets representing in themselves a plurality of independently closed magnetic circuits without air gap.
  • Lugs 39 serve to fast-ethe sheet metal lamellae and the lugs 31 correspond to the dot-forming ends of the printing elements 12 in FIG. 1 which on an energization of the coils 32 are caused to oscillate when in contact with the marking ribbon 26 of FIG. 1, for example.
  • the printing head 10 provided for the line-by-line application of the ink spots contains only one row of juxtaposed printing elements which may be individually excited magneto strictively.
  • the wires 12 or sheets 29 required for the printing of a given character may be energized by means of any known code converters which are interrogated in synchron-ism with the driving of the print medium.
  • th code converter as a result of an input signal representing a character, for example L, supplies output signals for exciting the wires 12 of FIG. 2 or the printing sheets 29 of FIG. 3.
  • the marking medium Zil for example, a sheet of carbon paper
  • the wires 12 or- ⁇ neets 29 would have to be excited in a reflected image representation of the characters.
  • the arrangement may be also operated at differential speeds.
  • a device for printing data on a moving print medium in a visible dot pattern comprising a body member having a bearing surface for said moving print medium, said body having a plurality of apertures arranged in a row in said bearing surface, a plurality of magneto strictively excitable stylus members located within said apertures, said stylus members having dot forming end portions flush with said bearing surface when in the unexc-ited state, means mounted on said body member for supporting said stylus members at their respective nodal point, and means for magnetostuictively exciting said stylus members for causing said dot forming end portions to be extended through said apertures beyond said bearing surface into dot forming impression contact with said print medium in accordance with a predetermined data forming pattern.
  • Printing means comprising a ferrite body member presenting a bearing surface for a moving print medium
  • said body member having a plurality of apertures ar- References Cited in the file of this patent UbiITED STATES PATENTS Toeppen et a1. May 21, 1957 Devol Oct. 29, 1957 Levin June 28, 1960
