Abstract
The print head includes a stationary block of non-conductive material having a plurality of openings into which spark jet capsules are received and a plurality of openings into which electrodes with off-set parts are received. Each electrode is located proximate the end of a different one of the capsules with the off-set part thereof situated in a channel on the block surface extending therebetween. The capsules are arranged in rows transverse to the direction of paper movement. The capsules in each of the rows are slightly off-set with respect to the corresponding capsules in the preceding row. The paper is moved continuously past the block. Actuation of the individual capsules is synchronized with the movement of the paper.
Claims19
A stationary head for a spark jet printer adapted to print on paper associated therewith, said head comprising a block of non-conductive material having a surface adapted to be proximate said paper and having a plurality of spark jet capsule receiving openings arranged in rows, said rows extending in a direction substantially transverse to the direction of paper movement, a plurality of electrode receiving openings, each of said electrode receiving openings being proximate a different one of said capsule receiving openings, and channels in the surface of said block proximate the paper extending between each of said electrode receiving openings and said capsule receiving opening proximate thereto.
A spark jet printer comprising means for feeding a paper to be printed upon, a plurality of spark jet capsules, a plurality of electrodes, each of said electrodes having an offset part, a block of non-conductive material having a surface adapted to be proximate said paper and having a plurality of spaced openings adapted to receive different ones of said capsules therein and a plurality of spaced openings adapted to receive different ones of said electrodes therein, each of said electrode receiving openings being situated proximate to a different one of said capsule receiving openings, said capsule receiving openings being arranged in rows, said rows extending in a direction substantially transverse to the direction of paper movement, channels in the surface of said block proximate the paper, extending between each of said electrode receiving openings and the capsule receiving openings proximate thereto and adapted to receive said offset parts therein, such that each of said offset parts are situated adjacent a different one of said capsules.
