ELECTRO-IONIC PRINTING APPARATUS |
摘要 |
<p>An improved printing head for forming electrostatic images on a dielectric surface by controlling the relative ion concentration in a gas stream moving through a slot and directed upon said dielectric surface. Application of an electric field across selected pairs of an array of spaced electrodes in the slot enables the stream to vary in ion concentration so as to cause the formation of a desired linear charge configuration on the dielectric. Selective application of low voltage electric fields to selected arrays of the electrodes causes formation of desired image charge configurations on the dielectric surface.</p> |
