    • A piezoelectric actuator comprising an elastic plate 2 with a projection 3 provided on one of both surfaces of the plate. A first pair of strip-like piezoelectric elements 120a, 120b are fixed to the other of both the surfaces of the plate such that each of the first pair of piezoelectric elements is disposed along a first straight line passing through the position of the projection on a respective one of its opposite sides. A second pair of strip-like piezoelectric elements 122a, 122b are fixed to the same surface of the plate as the first pair of piezoelectric elements 120a, 120b such that each of the second pair of piezoelectric elements is disposed along a second straight line passing through the position of the projection perpendicular to the first straight line on a respective one of opposite sides of the position of the projection. Voltages are arranged to be applied to the respective piezoelectric elements of the first and second pairs as required so as to deform the plate, thereby causing the projection to deviate.
    • 一种压电致动器,包括具有设置在板的两个表面中的一个上的突起3的弹性板2。 第一对条状压电元件120a,120b固定到板的两个表面中的另一个,使得第一对压电元件中的每一个沿着穿过突起的位置的第一直线设置 在相对的一侧。 第二对带状压电元件122a,122b固定到与第一对压电元件120a,120b相同的板的表面上,使得第二对压电元件中的每一个压电元件沿着第二对压电元件 直线穿过垂直于第一直线的突起的位置在投影的位置的相对的一侧上。 根据需要将电压设置为施加到第一对和第二对的各个压电元件,以使板变形,从而导致突起偏离。
