    摘要: An ink jet printing head includes a pressure chamber supplied with ink, a vibration plate, a nozzle, a force applying mechanism and a resilient member. The vibration plate is coupled to the pressure chamber and is subject to being driven in vibration to increase pressure in the pressure chamber when force is applied to the vibration plate. The nozzle communicates with the pressure chamber, and ink is ejected through the nozzle when pressure in the pressure chamber is increased. The force applying mechanism applies force to the vibration plate to drive the vibration plate in vibration and thereby increase the pressure in the pressure chamber to eject ink from the nozzle. The resilient member is interposed between the pressure chamber and the vibration plate. The resilient member resiliently supports the vibration plate relative to the pressure chamber.
