Translation to rotation conversion in an inkjet printhead

Abstract

A printhead chip for an inkjet printhead includes a substrate. A plurality of nozzle arrangements is positioned on the substrate. Each nozzle arrangement includes nozzle chamber walls and a roof that define a nozzle chamber. The roof defines an ink ejection port that is in fluid communication with the nozzle chamber. An actuator is displaceable, in a substantially rectilinear manner, with respect to the substrate. An ink-ejecting mechanism is angularly displaceable with respect to the substrate to eject ink from the ink ejection port. A translation to rotation conversion mechanism is interposed between the actuator and the ink-ejecting mechanism to convert rectilinear movement of the actuator into angular displacement of the ink-ejecting mechanism.
