Abstract
Abstract A recording apparatus in which a plurality of recording elements supplied with a liquid imaging material and having ends for dispensing such material are disposed in side-byside, spaced relationship transversely of a recording member positioned in underlying relationship with the dispensing ends of the recording elements and continuously advanced by suitable means relative to the elements together with electrically operated control means responsive to an image to be reproduced for controlling the dispensing of the imaging material from the elements so as to selectively dispense the imaging material from the elements and apply an assembly of rows of intermittent, linear marks to said recording member with said marks arranged in transversely spaced, parallel relationship corresponding to the spacing of said elements to form a reproduction of said image on said recording member.

Claim 1
Independent Claim
344 words
A recording apparatus comprising: a plurality of recording elements, each thereof comprising a hollow tubular nozzle having an outlet end for dispensing a liquid imaging material; means for supplying said liquid imaging material to said plurality of recording elements; a recording member disposed in close, opposing relationship to said recording elements adjacent said dispensing outlet ends thereof; means for advancing said recording member relative to said recording element; said plurality of recording elements being arranged relatively to one another and to said recording member so that images formed by said recording elements on the surface of said recording member are arranged in spaced, parallel relationship corresponding to the relative spacing of said recording elements in a direction transverse of said recording member; and electrically operated control means responsive to an image to be reproduced and operatively associated with said recording elements for selectively controlling the dispensing of said liquid imaging material from the outlet ends of each of said recording elements for application of said liquid material to said relatively advancing recording member in an assemblage of rows of intermittent linear marks arranged in said transversely spaced, parallel relationship corresponding to the arrangement of said recording elements relatively to one another, said control means including for each said recording element: an electrode plate having a through hole coaxial with the nozzle outlet end and disposed between said nozzle and said recording member; a ring disposed coaxially with said nozzle adjacent said nozzle outlet end; means for applying a voltage between said nozzle and said electrode plate to establish an electric field therebetween thereby to direct a convergent jet of said liquid imaging material through the through hole of said electrode plate and onto said advancing recording member; and means for applying intermittently a voltage to said ring in response to said image to be reproduced of the same polarity as said voltage applied between said nozzle and said electrode plate for reducing the said electric field established thereby and stopping the jet, thereby to form a reproduction of said image on said recording member.
Claim 2
Dependent Claim
344 words
A recording apparatus comprising: a plurality of recording elements, each thereof comprising a hollow tubular nozzle having an outlet end for dispensing a liquid imaging material; means for supplying said liquid imaging material to said plurality of recording elements; a recording member disposed in close, opposing relationship to said recording elements adjacent said dispensing outlet ends thereof; means for advancing said recording member relative to said recording element; said plurality of recording elements being arranged relatively to one another and to said recording member so that images formed by said recording elements on the surface of said recording member are arranged in spaced, parallel relationship corresponding to the relative spacing of said recording elements in a direction transverse of said recording member; and electrically operated control means responsive to an image to be reproduced and operatively associated with said recording elements for selectively controlling the dispensing of said liquid imaging material from the outlet ends of each of said recording elements for application of said liquid material to said relatively advancing recording member in an assemblage of rows of intermittent linear marks arranged in said transversely spaced, parallel relationship corresponding to the arrangement of said recording elements relatively to one another, said control means including for each said recording element: an electrode plate having a through hole coaxial with the nozzle outlet end and disposed between said nozzle and said recording member; a ring disposed coaxially with said nozzle adjacent said nozzle outlet end; means for applying a voltage between said nozzle and said electrode plate to establish an electric field therebetween thereby to direct a convergent jet of said liquid imaging material through the through hole of said electrode plate and onto said advancing recording member; and means for applying intermittently a voltage to said ring in response to said image to be reproduced of the same polarity as said voltage applied between said nozzle and said electrode plate for reducing the said electric field established thereby and stopping the jet, thereby to form a reproduction of said image on said recording member.
