    • A vibration type driving device in which a piezoelectric element is interposed between a pair of blocks connected to each other by a rod, a part of the surface of the piezoelectric element being covered with an electrode. Application of high frequency voltage to the electrode causes resonance of vertical vibrations and bending vibrations, which is effective to generate elliptical movement of the end surface of the block. The electrode is divided into three or more sections, preferably into four sections. A change-over switch is provided for selecting the electrode sections to be energized in accordance with the direction of the driving force. This permits linear movement of an article in a desired direction.
    • 一种振动型驱动装置,其中压电元件插在通过杆彼此连接的一对块之间,压电元件的表面的一部分被电极覆盖。 对电极施加高频电压引起垂直振动和弯曲振动的共振,这有助于产生块的端面的椭圆运动。 电极分为三个或更多个部分,优选分为四个部分。 提供转换开关,用于根据驱动力的方向选择要被激励的电极部分。 这允许制品在所需方向上的线性运动。
