Nozzle arrangement for an ink jet printhead incorporating a linear spring mechanism

An ink jet printhead that is the product of an integrated circuit fabrication technique, the ink jet printhead comprising

• a substrate;
• and
• a plurality of nozzle arrangements arranged on the substrate, each nozzle arrangement having an actuating mechanism that is arranged on the substrate, each 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.
