DRIVING GEAR AND RECORDING AND/OR REPRODUCING DEVICE USING THE SAME

PROBLEM TO BE SOLVED: To improve a bonding strength between a vibrator and an elastic body, and to improve transfer characteristics of vibrations generated by a vibrating member. SOLUTION: This driving gear is provided with a mounting block 32 on which an optical pickup 8 is mounted, a guide shaft 33 that supports the mounting block 32 movably, and a vibrating member 44. A first electrode 63 and a second electrode 64 are provided on each surface of a piezoelectric element 62 of this vibrating member 44. AC voltages of different phases are impressed to the first electrode 63 and the second electrode 64 to make the piezoelectric element 62 expand and contract. The vibrating member 44 makes a sliding portion 65, which contacts the mounting block 32, move roughly elliptically in such a way that it gets close to and apart from a contact surface 32a of the mounting block 32. The sliding portion 65 is structured by soldering the elastic body 65a on a soldered portion 65c of the piezoelectric element 62. COPYRIGHT: (C)2004,JPO&NCIPI
