<P>PROBLEM TO BE SOLVED: To provide a driving device for surface acoustic waves, capable of adjusting a load by which the driving effect of a driver for the surface acoustic waves can be secured. <P>SOLUTION: The driving device for the surface acoustic wave comprises a positioning flat base 10, the driver 20 for the surface acoustic waves, a sliding part 30, and a support structure 40. The positioning flat base 10 has sliding bearings 11 on both sides, and the driver 20 for the surface acoustic wave is installed on the positioning flat base 10 so as to be located between the two sliding bearings 11 and generates the surface acoustic waves on the uppermost end face. The sliding part 30 is installed on the positioning flat base 10 and has a load part 33 coming into contact with the uppermost end face of the driver 20 for the surface acoustic waves and two positioning parts 32, respectively located to the sliding bearings 11. The sliding part 30 is moved guided by the surface acoustic waves of the driver 20 for the surface acoustic waves. The support structure 40 applies prescribed force to the positioning part 32 corresponding to the degree of the load of the sliding part 30. Contact pressure between the sliding part 30 and the driver 20 for the surface acoustic waves is held to be within a fixed value. <P>COPYRIGHT: (C)2005,JPO&NCIPI |
