PURPOSE:To provide a printing unit reduced in power consumption and having a small volume, constituted by mounting a piezoelectric body generating piezoelectric vertical effect, a special connecting member and a movable member. CONSTITUTION:A piezoelectric body generating stress by piezoelectric vertical effect is fixedly attached to a fixing member 2 at one end thereof an to a first connecting member 10 at the other end thereof. To this connecting member 10, a second and a third connecting members 12, 14 are integrally provided and a second connecting member 12 is connected to one end of a first movable member 13 to which a fourth connecting member 16 is connected at a place leaving a predetermined interval from the second connecting member 12. To a second movable member 15, a fifth connecting member 18 is connected at a place leaving predetermined interval from the third connecting member 14 and the fourth and the fifth connecting members 16, 18 are connected to the end part of the fixing member 2. One ends of a sixth and a seventh connecting members 20, 22 are fixedly connected to the other ends of the first and the second movable members 13, 15 while these other ends are fixedly attached to a third movable member 21 and a pin 24 is attached to the leading end thereof. |
