PRINTHEAD MICRO-ELECTROMECHANICAL NOZZLE ARRANGEMENT WITH MOTION-TRANSMITTING STRUCTURE

摘要

A micro-electromechanical nozzle arrangement for a printhead integrated circuit the nozzle arrangement includes a nozzle chamber bounded by a distal sidewall and a proximal sidewall, and capped by a roof defining an ink ejection port; a paddle located in the nozzle chamber below the ink ejection port; an actuator arm positioned outside of the nozzle chamber in the vicinity of the proximal sidewall, the actuator arm having a fixed end fixed to a substrate of the nozzle arrangement and a working end displaceable towards and away from the substrate; and a motion transmitting structure interconnecting the working end of the actuator arm and the paddle. The motion transmitting structure defines part of the proximal sidewall.
