Abstract
Abstract A deflection electrode assembly for an ink jet type printing device has such a construction that plural X- and Y-axis deflection electrodes etch-formed from an electroconductive plate overlie an opening of an insulating substrate through which ink droplets jetted from plural juxtaposed nozzles can be passed all at a time.

Claims Analysis
Total Claims: 6
Claim 1
Independent Claim
104 words
A deflection electrode assembly for an ink jet type printing device comprising an insulating substrate having an opening through which ink droplets from plural nozzles can be passed, a first group of electrodes oppositely facing in pairs at an interval with an ink passageway left therebetween, and a second group of electrodes whose pairs sandwich the paired first electrodes in a spaced apart relationship to define said ink passageway together with the paired first electrodes, said first and second groups of electrodes attached to one surface of the insulating substrate and forming paired vertical and horizontal electrodes corresponding to each of the plural nozzles.
Claim 2
Dependent Claim
104 words
A deflection electrode assembly for an ink jet type printing device comprising an insulating substrate having an opening through which ink droplets from plural nozzles can be passed, a first group of electrodes oppositely facing in pairs at an interval with an ink passageway left therebetween, and a second group of electrodes whose pairs sandwich the paired first electrodes in a spaced apart relationship to define said ink passageway together with the paired first electrodes, said first and second groups of electrodes attached to one surface of the insulating substrate and forming paired vertical and horizontal electrodes corresponding to each of the plural nozzles.
Claim 3
Dependent Claim
160 words
A deflection electrode assembly for an ink jet type printing device comprising an insulating substrate having an opening through which ink droplets from plural nozzles can be passed, a first group of electrodes oppositely facing in pairs at an interval with an ink passageway left therebetween, a second group of electrodes whose pairs sandwich the paired first electrodes in a spaced apart relationship to define said ink passageway together with the paired first electrodes, said first and second groups of electrodes attached to one surface of the insulating substrate, and third and fourth groups of electrodes attached to the other surface of the insulating substrate and being in a symmetrical relationship to the plane of the insulating substrate, said first and third grouped electrodes and said second and fourth grouped electrodes having a deflection area in a direction of the thickness of the insulating substrate and respectively forming vertical and horizontal deflection electrodes corresponding to each of the plural nozzles.
Claim 4
Dependent Claim

A deflection electrode assembly for an ink jet type printing device comprising an insulating substrate having an opening through which ink droplets from plural nozzles can be passed, a first group of electrodes oppositely facing in pairs at an interval with an ink passageway left therebetween, a second group of electrodes whose pairs sandwich the paired first electrodes in a spaced apart relationship to define said ink passageway together with the paired first electrodes, said first and second groups of electrodes attached to one surface of the insulating substrate, and third and fourth groups of electrodes attached to the other surface of the insulating substrate and being in a symmetrical relationship to the plane of the insulating substrate, said first and third grouped electrodes and said second and fourth grouped electrodes having a deflection area in a direction of the thickness of the insulating substrate and respectively forming vertical and horizontal deflection electrodes corresponding to each of the plural nozzles.
Claim 5
Independent Claim
126 words
A method for manufacturing a deflection electrode assembly for an ink jet type printing device comprising the steps of (1) etch-forming, from an electroconductive plate, paired vertical and horizontal deflection electrode sections arranged in a predetermined interval while leaving the peripheral marginal portions intact; (2) attaching the electroconductive plate having the paired vertical and horizontal electrode sections etch-formed by (1), to an insulating substrate having an opening through which ink droplets from plural nozzles can be pAssed; (3) cutting the opposite peripheral marginal portions of the resultant electroconductive plate-insulating substrate assembly integrally formed by (2) to leave the vertical and horizontal electrode sections of the electroconductive plate, whereby pairs of independent deflection electrodes are formed in a manner to face the opening of the insulating substrate.
