Claims
- 1. A deflecting electrode assembly for deflecting parallel trains of ink droplets in an ink jet printer, each train of ink droplets being generated by an ink jet, said ink jets being disposed in a line so that said train of ink droplets travels in a common plane, thus forming a first plane of ink droplets, comprising:
- an upper and a lower deflecting electrode, said deflecting electrodes being equal in width and parallel to one another, a second plane containing said lower deflecting electrode being parallel to said first plane of ink droplets, a longitudinal central line of said lower deflecting electrode in said second plane being parallel to a direction of travel of said trains of ink droplets, a first distance (d) between said first plane of ink droplets and said lower deflecting electrode being: 0.2 mm.ltoreq.d.ltoreq.0.4 mm, a second distance (b) measured from a central line between an outermost train of ink droplets and a train of ink droplet adjacent thereto to an outer edge of said lower deflecting electrode being at least 5 times a third distance (c) between adjacent trains of ink droplets, said outer edge of said lower deflecting electrode extending past said outermost train of ink droplets, and a fourth distance (a) between said upper and lower electrodes being 1 mm.ltoreq.a.ltoreq.2 mm.
- 2. The deflecting electrode assembly claimed in claim 1 wherein said longitudinal central line of said lower deflecting electrode is equidistant from said outermost trains of ink droplets.
- 3. The deflecting electrode assembly claimed in claim 1 wherein said upper and lower deflecting electrodes are made of a metal material.
- 4. The deflecting electrode assembly claimed in claim 3 wherein said metal material is stainless steel.
