Kind Code:

B2

Abstract:

Modulated apertured non-contact electrostatic printing wherein a stream of ions is modulated by passage through one or more rows of electrically addressed apertures containing bipolar electrostatic fringing fields of force into a mist of uncharged toner particles to impinge upon such particles causing them to become charged and attracted onto a print receiving medium. Specified particle modulator constructions wherein a plurality of very small closely spaced modulating apertures are positioned on a flexible printed circuit board having printed circuit lead lines extending between each aperture and printed terminal pads. The terminal pads are arranged in straight parallel rows for attachment to conventional printed circuit card edge connectors and, thereby, to printed circuit cards carrying control circuitry. Each of the printed circuit leads joining one of the apertures to one of the terminal contact pads is comprised of a first section extending from the aperture in a direction substantially perpendicular to the rows of apertures, and a second section extending in a direction substantially parallel to the rows of apertures between the distal end of the first section and one of the terminal contact pads. The circuit board is fabricated from a flexible dielectric substrate having a continuous electrically conductive backing. The printed circuitry, including the aforementioned lead lines and terminal contact pads, appears upon the opposite side of the substrate. The terminal contact pads are positioned on a flexible flap cut in the flexible circuit board and are electrically connected to conventional circuit card edge connectors which have two rows of terminal prongs depending therefrom by wrapping the flap across an elongate filler block with the terminal contact pads facing upwardly in alignment with the terminal prongs, wedging the flap between the rows of terminal prongs and the filler block and soldering the terminal prongs to the pads.
