- FIGS. 18A and 18B In order to simplify the description as described above, the model shown in FIGS. 18A and 18B has been described. However, based on the same concept, the actual machine unit 2 shown in FIG. 14 is configured. ing.
- the mechanical device unit 202 in the present embodiment generates vibrations in the K and Y directions in the K and Y directions with respect to the movable body 206 and the intermediate stage 205, and thus the excitation force described above is used.
- Piezoelectric elements 281 to 282 are provided as the excitation means for applying as follows.
- a rectangular parallelepiped first surface is formed on a surface perpendicular to the K axis on the side surface of the spring portion 272b of the second rod-shaped spring member 272 that is not longer than the center in the longitudinal direction.

Therefore, the first rod-shaped spring member 271 functions as a vibration-proof spring and flexibly supports the intermediate base 205 and the movable body 206. By doing so, the reaction force due to the operation of the intermediate platform 205 and the movable body 206 is not transmitted to the base 204, and it is possible to stably maintain the support state with respect to the installation surface.

Therefore, when one side is set as the extension side, the voltage application and the attaching direction are set so that the other side becomes the contraction side.
- the voltage applied to the piezoelectric element will be described simply as a K-direction control voltage and a Y-direction control voltage, and applying a positive control voltage in the K-direction and the Y-direction means that the movable body 206 is used.
- the extending side and the contracting side are reversed up and down in one plane with the center in the longitudinal direction as a boundary. Therefore, attaching the first piezoelectric element 281 and the second piezoelectric element 282 to a wide range beyond the vicinity of the center in the longitudinal direction is not preferable because it hinders deformation. For this reason, it is efficient to attach it to a position closer to one end side than the vicinity of the center in the longitudinal direction as in this embodiment.

- W1 proceeds in the negative direction and W2 proceeds in the positive direction. Further, at ⁇ 5, the speed of W2 becomes 0, and W1 advances in the negative direction. In the range of ⁇ 5 to ⁇ , both proceed in the negative direction. Among them, the speed is the same at ⁇ 5, and the speed is reversed before and after that. Such a relationship also applies to the movement speed Vy in the Y direction.
- the relationship between the phase difference ⁇ x ( ⁇ y) and the moving speed Vx (Vy) of the article 9 is expressed by the amplitude X 0 ( It is also changed by changing Y 0 ). That is, a sine wave-like curve that is the moving speed Vx (Vy) of the article 9 with respect to the phase difference ⁇ x ( ⁇ y) changes approximately in proportion to the amplitude X 0 (Y 0 ) of the vibration displacement. From this, when it is desired to double the moving speed Vx (Vy) of the article 9, the amplitude of the vibration displacement in the X (Y) direction may be almost doubled. For that purpose, the amplitude of the control voltage may be changed in order to give a corresponding excitation force.
