Definitions

  • a paper supporting platen which is a tellurium ion bearing electrode cooperates with a plurality of opposite arranged pins.
  • the electrode and the pin are connected to a mosaic character generator.
  • An ionizing means is provided to ionize the gas contained in the paper in the area between the platen and pins so as to provide the conductivity required between the electrode and pins to deposit ionson the paper according to the energization of the mosaic character generator.
  • this invention relates to electrical printing systems, and more particularly to the type of electrical printing systems in which ions from an electrode are deposited on a paper printing medium to produce a permanent mark thereon.
  • Another object of this invention is to describe a method of printing in which the gas contained in the printing medium is ionized to permit the deposit of ions from a tellurium ion bearing electrode so that printing may be accomplished in an inexpensive wetless manner.
  • a paper supporting platen which is a tellurium ion bearing electrode cooperates with a plurality of oppositely arranged pins, and includes means to ionize the gas contained within the open interstices between the fibers of tates Patent Oifice Patented Nov. 17, 1970 the paper so as to provide the conductivity required between the electrode and pins to deposit the ions on the paper.
  • a feature of this invention is that there is provided a tellurium platen which supports the printing paper and oppositely disposed are a number of fine tungsten or platen wires making connections to the other face of the paper.
  • the tungsten or platen wires are connected through a mosaic character generator which is also connected to the tellurium platen. Logic energization of the generator causes ionization of the air in the paper.
  • mosaic character generator connecting wires and platen may incorporate -R.F. or sufficiently high D.C. exitation to induce ionization of the gas contained in the paper and as such achieve the rapid plating.
  • Yet another feature of this invention is to incorporate separate ionizing means which may be directed at the position of printing such as a radiating isotope in close proximity to the region to be ionized.
  • a beta emitter may be used, or an ultraviolet or X-ray emitter alone, or in combination with the exitation produced by the mosaic character generator.
  • FIG. 1 illustrates one embodiment vention
  • FIG. 2 represents another embodiment according to the invention.
  • FIG. 1 one embodiment of the invention is shown in which a mosaic character generator 10 is connected by lines 11 to a platen 12 and a writing head 13.
  • Platen 12 is a tellurium ion bearing platen and forms one electrode.
  • Writing head 13 has a plurality of pins 14 comprised of fine tungsten or platinum wires and positioned so that across paper 15 there may be applied a potential as developed by the character generator 10. The spacing between adjacent pins 14 should be several times the thickness of paper 15.
  • the logic circuits in the mosaic generator should be designed so that the unselected pins are substantially open rather than being grounded, or held at some other fixed potential.
  • each selected pin should be energized by a high resistance in order to limit the current to a reasonable value.
  • the writing head 13 is moved by means of a driving spindle 16, and is movable in the directions of arrows 17.
  • the paper 15 from paper roller 18 is fed in the direction indicated by arrow 19.
  • the gas to be ionized could be the normal air already existing in the paper or somewhat different from normal air.
  • FIG. 1 indicates the pin forming the positive electrode and the platen forming a negative electrode as would be the case in DC, other methods to achieve such ionization would be in the use of an RF. mosaic character generator, wherein the RF. excitation is applied between the pins 14 and the platen 12. It should be also understood that the ionization may be applied by means of another according to the inhead in close proximity to head 15, this additional head performing the sole function of ionization of the gas con tained within the paper.
  • FIG. 2 another embodiment'of this invention is illustrated which shows an independent ionizing means 21.
  • Independent ionizing means 21 may be a radiating isotope in close proximity to the region Where the printing is to be performed.
  • the radiating rays indicated by lines 22 will ionize the gas contained within the printing region, and thereby permit lower energy levels to be employed in mosaic character genera-tor 10.
  • a beta emitter alone may be used, or the combination of a beta emitter and R.F. excitation from generator 10.
  • Ionizing means 21 could employ ultraviolet or X-rays alone, or in combination with R.F. excitation to ionize the gas contained within paper 15.
  • the embodiment ilus-trated in FIG. 2 permits many combinations and probabilities, the initial field to induce ionization may be produced by ionizing means 21, and this ionization is then kept alive by RF. excitation or high D.C. field excitation to affect the printing process.
  • a printing apparatus comprising:
  • a tellurium platen electrode supporting the printing a plurality of pins making contact to the front of said a high voltage mosaic character generating means coupled for selectively energizing said pins and electrode;
  • said generating means causing a current to be passed between said platen and selectively energized pins for depositing tellurium ions in the ionized area of the printing paper to produce a permanent mark thereon.
  • said means for radiating include means focused to said area and emitting a beta ray, ultraviolet ray or X-ray.
