发明名称 PIEZO DRIVE SYSTEM
摘要 A piezo drive system includes an elastic fixing frame, a drive element, a rod, and a rotor. A vamplate portion is formed on the outer surface of the rod. One end of the rod is secured to around the center of a face of the drive element. The rotor consists of a cylindrical portion and a disk portion, and can rotate relative to the rod. Protrusions are formed on the inside of a top surface portion of the fixing frame to push against the disk portion. Using the drive element, the rod rotates while tilting and makes a surface contact with the vamplate portion, producing friction. Consequently, the rotor is rotated.
