Claims

[Scope of utility model registration request]

A nozzle and means for ejecting ink droplets from the nozzle are disposed at the lower end of the support, and an ink flow path is provided in the support at a position above the means for ejecting ink droplets from the nozzle. In the head of a so-called inkjet printer, which has an ink tank mounted on the top surface, when electric pulses are applied to the nozzles arranged at multiple locations and the corresponding positions, mechanical vibration means or heat generation occurs. A substrate is provided with a portion having the function of ejecting ink droplets by a means, and an ink supply hole communicating with an ink tank is provided in the substrate, and the ink is guided toward the nozzle group from the ink supply hole, and the above-mentioned An inkjet printer head characterized by having a group of nozzles positioned below the platen roll in the direction of gravity and having pigment ink loaded in an ink tank.
