Definitions

  • FIG. 7 is a schematic representation of a printout arrangement including a developer.
  • a gas discharge matrix for a highspeed printer comprising first and second parallely disposed electrodes shown at 2 and 3, respectively, separated by a perforated insulating medium 4.
  • a pair of spaced electrodes as, for example, the electrodes shown at A and B in FIG. 2 within each of the perforations or cavities 5 of the matrix are adapted to ionize a gas (which can be air) therein upon response to an electric signal from a signal source 14 connected therebetween.
  • the electrodes A are shown connected serially together, and the electrodes B, designated B B B B etc., are individually energized.
  • the electrodes A can be connected to one side of a source of signals as a common input and the electrodes B can be individually electrically energized in some detemiined pattern.
  • perforations 5 form a unit or group and by appropriately energizing the required electrodes A and B the letter F, as shown, can be formed.
  • An electric potential 6 connected between the first and second electrodes maintains the gas in the ionized state once ionization has been initiated.
