Abstract

Abstract Printing means for high-speed non-impact printers of the type having character-shaped, pulsed electrodes. Mutually facing electrode and terminal sheets have insulating bases upon the nonfacing surfaces of which are disposed character electrodes and corresponding connection terminals. The respective electrodes and terminals are mutually connected by conductor leads extending through the sheets. Surrounding portions of the non-facing surfaces and portions of the facing surfaces extend about the electrodes and terminals and are electrically conductive and connectable to circuit means for the purpose of shielding and suppressing arcs between electrodes or between terminals, or between electrodes and terminals.

Claims Analysis

Total Claims: 12
Claim 1
Independent Claim 138 words
Printing means having, in combination, an electrode sheet comprising an insulating base and a plurality of character-shaped electrodes arranged in a pattern on a surface thereof, said surface having a conductive portion substantially surrounding the region including said pattern without electrically contacting said electrodes, a terminal sheet having a surface facing the other surface of said electrode sheet and comprising an insulating base and a plurality of mutually spaced electrically conductive strips on the non-facing surface thereof, each strip corresponding to an electrode on the first sheet and having a first end and a second end, the first ends of said strips being aligned with said pattern and the second ends having terminal means, and a lead extending through the bases of said sheets and electrically connecting each said electrode with the first end of a corresponding strip.
Claim 2
Dependent Claim 138 words
Printing means having, in combination, an electrode sheet comprising an insulating base and a plurality of character-shaped electrodes arranged in a pattern on a surface thereof, said surface having a conductive portion substantially surrounding the region including said pattern without electrically contacting said electrodes, a terminal sheet having a surface facing the other surface of said electrode sheet and comprising an insulating base and a plurality of mutually spaced electrically conductive strips on the non-facing surface thereof, each strip corresponding to an electrode on the first sheet and having a first end and a second end, the first ends of said strips being aligned with said pattern and the second ends having terminal means, and a lead extending through the bases of said sheets and electrically connecting each said electrode with the first end of a corresponding strip.
Claim 3
Dependent Claim 13 words
