Inkjet printhead having compact inkjet nozzles

摘要

An inkjet printhead having ink ejection nozzles arranged on a substrate is provided. Each ink ejection nozzle comprises an ink chamber, an ink ejection port arranged on the ink chamber, and a multiple-armed actuator arranged to be displaced relative to the ink chamber so as to cause ejection of ink from the ink ejection port. The actuator is displaced through actuation of at least one arm. A first arm of the actuator is anchored to the substrate via a first anchor which receives an actuation signal for actuating the first arm. A second arm of the actuator is anchored to the substrate via a second anchor. At one of the first and second anchors is positioned between the ink chamber and the respective first and second arm.
