摘要： A droplet generator for a continuous stream ink jet print head includes an elongate cavity for containing the ink, nozzle orifices in a wall of the cavity for passing ink from the cavity to form jets. The nozzle orifices extend along the length of the cavity. An actuator is disposed on the opposite side of the cavity to the wall for vibrating the ink in the cavity by itself vibrating relative to the wall. The vibration is such that each jet breaks up into ink droplets at the same predetermined distance from the wall of the cavity. The thickness of the wall through which the nozzle orifices extend is less than 90 &mgr;m. The wall includes a planar member secured to the remainder of the droplet generator so as to form a boundary which extends around the nozzle orifices and within which the planar member is unsupported. The boundary includes first and second boundary lengths which extend along the length of the cavity on either side of the nozzle orifices. The distance between the first and second boundary lengths being less than 1700 &mgr;m.

摘要： A continuous stream ink jet print head comprising: a droplet generator (1) for generating a continuous stream of ink droplets; a charging electrode (40) for selectively charging the ink droplets; deflection electrodes (4) for deflecting the charged ink droplets; and a catcher (7) for collecting uncharged ink droplets, wherein the deflection electrodes are contained within a surrounding structure (2) that both (i) provides surfaces (41) which are contoured to the shape of the main bodies of the deflection electrodes such that the main bodies may be mounted against the surfaces to correctly position the deflection electrodes within the print head, and (ii) serves as a manifold for fluid in operation of the print head, wherein the print head includes a cover (10) for the surrounding structure, the cover forming a wall of the space between the deflection electrodes, the wall extending along the stream of ink droplets.
