摘要：
A nozzle head of an ink-jet printing apparatus according to the present invention comprises an ink reservoir for storing the ink supplied from an ink tank, a pump chamber provided between said ink reservoir and a nozzle for injecting ink particles, and a fluid diode provided between said ink reservoir and said pump chamber, which are all formed in a same substrate, wherein said pump chamber is caused to change its volume responsive to electric signals so that the ink stored therein is injected from said nozzle, and the ink is prevented from reversely flowing from said pump chamber to said ink reservoir when the volume of the pump chamber is changed, thereby to improve the frequency response of ink particles injected from the nozzle.
