いる。FIG. 5 is a partial sectional view showing an example of an inkjet head using the amplitude conversion actuator shown in FIG. The amplitude conversion actuator 1 has a base portion 1d fixed to the head casing 5, and a protrusion 1c of the weight portion 1b.
is in contact with the end surface 2a of the piezoelectric element 2, which is a vibrating element. 3 is a nozzle plate having a nozzle orifice 3a.

移り、圧電素子２の端面２ａと接して初期状態となる。When a pulse is applied to the piezoelectric element 2 in the configuration shown in FIG. 5, if the piezoelectric element 2 is a piezoelectric element that expands at the rising pulse, the piezoelectric element 2 will expand steeply, and its end surface 2a will cause the weight part of the amplitude conversion actuator to 1b is pushed and approaches the nozzle orifice 3a. When a falling pulse is applied here, the expansion of the piezoelectric element 2 is reversed to contraction.However, since the movement of the weight part 1b toward the nozzle orifice is not restrained by the piezoelectric element 2, the plate spring part 1a Due to the cycle formed by the relationship between the springiness and the weight of the weight portion 1b, the nozzle orifice 3a is further approached.
The speed becomes 0 at the point where it touches the nozzle plate 3. Next, the weight portion 1b moves to a return stroke due to the springiness of the leaf spring portion 1a, and comes into contact with the end surface 2a of the piezoelectric element 2 to be in the initial state.

フィス３ａよりインク４がインク滴として吐出する。The vibrations of these movements generate pressure, and the ink 4 is ejected as ink droplets from the nozzle orifice 3a.

加させる事で介在するインクを排除する事ができる。During these movements, the weight portion 1b returns from the nozzle plate 3 and when it comes into contact with the piezoelectric element 2, the end surface 2 of the piezoelectric element 2
If the ink 4 is present between the contact point and the contact point a, it becomes an obstacle to good contact. Therefore, as shown in FIG.
By providing the protrusion 1c on the contact surface with the end surface 2a of the piezoelectric element 2, the contact area can be reduced and the intervening ink can be removed by increasing the pressing force.
また、振幅変換アクチュエーターｌがインク中で振動す
る為、インクの抵抗が大きいと、振動の減衰が生じて、
所定の振幅を得る事に障害となる。Also, since the amplitude conversion actuator l vibrates in the ink, if the resistance of the ink is large, the vibration will be attenuated.
This becomes an obstacle to obtaining a predetermined amplitude.
そこで、第２図に示したように振幅変換アクチュエータ

アクチュエーターの振動減衰を最小限にとどめ、安定し

。Therefore, as shown in FIG. 2, by making the surface area of the leaf spring part 1a smaller than the surface area of the ink pressurizing surface (i.e., the weight part 1b) of the amplitude conversion actuator 1, the vibration damping of the amplitude conversion actuator can be minimized. It is possible to achieve stable vibration characteristics and obtain good printing quality.
