Claims

[Scope of utility model registration request]

In a multi-nozzle print head that uses a plurality of ejection heads that eject ink droplets from nozzles by applying voltage to a piezo vibrator and changing the volume of a pressure wave generation chamber, one end of each pressure wave generation chamber is connected to an ink tank. providing a capacity chamber communicating with each other and having a smaller volume than each of the pressure wave generation chambers between each of the pressure wave generation chambers and the nozzle;
a pressure wave generation substrate provided with an ink supply hole that communicates with the capacity chamber and a second ink supply section described later; and an ink bonded to the pressure wave generation substrate to directly communicate the ink supply hole and the ink tank. An ink supply path substrate in which a supply section is arranged independently for each capacity chamber, a thin combustible plate bonded to the pressure wave generation substrate, and an instantaneous change in volume of the pressure wave generation chamber. A multi-nozzle print head comprising rectangular piezo vibrators attached to the flexible plate in correspondence with the pressure wave generation chambers.
