Abstract:
A nozzle arrangement for an ink jet printhead that is the product of an integrated circuit fabrication technique, the nozzle arrangement comprisinga substrate; and an actuating mechanism that is arranged on the substrate, the actuating mechanism comprising an anchor member that is fast with the substrate; an effort member that is displaceable with respect to the anchor member; a resiliently flexible connector that is fixed between the anchor member and the effort member, the connector, the anchor member and the effort member defining a linear spring so that a force applied to the effort member in a first direction relative to the anchor member results in constrained displacement of the effort member in a second direction relative to the substrate, the second direction having at least two vector components, one of which is in said first direction and another is in a third direction at right angles to said first direction with the displacement of the effort member incorporating substantially no rotational movement; and an effort mechanism that is arranged on the substrate and is operable on the effort member to apply said force to the effort member in said first direction.
