Abstract
An ink jet nozzle head including a channel plate defining a linear array of equidistanced nozzles and a plurality of substantially parallel ink channels communicating with an associated nozzle, a vibration plate disposed on the channel plate, a plurality of separately disposed block members, each containing a comb-like array of fingers which extend toward and engage the vibration plate, some fingers functioning as actuators for exerting mechanical pressure on ink contained in the ink channels which in turn expels ink droplets from the nozzle, at least one actuator being provided for each nozzle, and other fingers serving as support members for supporting the actuators at the vibration plate, where the reaction forces of the actuators are received, wherein each block comprises at least one actuator and at least one support member.
