Droplet discharge head and method of manufacturing the same, ink cartridge and ink-jet recording apparatus

摘要

PROBLEM TO BE SOLVED: To solve the problem of a decrease of a mechanical strength of a channel forming member because jetting failures are brought about by an increase of cross talk via a common liquid chamber in accordance with high density construction of a head.;SOLUTION: The liquid droplet jetting head has a channel plate 1, a diaphragm 2 and a frame member 11. Channel patterns including a plurality of pressurization liquid chambers 6 which communicate with nozzles 4 for jetting ink droplets via a nozzle communication path 5 are formed independently of each other at the channel plate 1. The common liquid chamber 8 is formed at the frame member 11. Moreover, ink inflow openings 9 formed independently of each other corresponding to the channel patterns including each pressurization liquid chamber 6 are interposed between the channel plate 1 and the frame member 11.;COPYRIGHT: (C)2004,JPO
