LIQUID-EJECTING HEAD AND LIQUID-EJECTING APPARATUS |
摘要 |
A liquid-ejecting head includes a nozzle plate having a nozzle opening that serves for liquid ejection; a channel-forming substrate including pressure-generating chambers that are in communication with the nozzle opening; a pressure generator that serves to generate pressure change in a liquid in the pressure-generating chambers; and a communication plate provided between the nozzle plate and the channel-forming substrate, the communication plate having a communication channel that forms a communication between the pressure-generating chambers and the nozzle opening. The communication plate has a circulation channel that is in communication with a common liquid chamber through the communication channel, the common liquid chamber being in communication with a plurality of the pressure-generating chambers in common. |
