Title:
FINE ADJUSTMENT DEVICE
Document Type and Number:
Japanese Patent JPS6095271
Kind Code:
A
Abstract:
PURPOSE:To make it possible to perform low voltage drive, by disposing a lamination type piezo element between shafts, and by providing cylindrical piezo elements on the outer peripheral surfaces of the shafts. CONSTITUTION:A lamination type piezo element 9 is held between shafts 12, 13 by means of holding members 10, 11, and cylindrical piezo elements 14, 15 are provided on the outer peripheral surfaces of the shafts 12, 13. With this arrangement, the longitudinal effect distortion of the elements may be effectively utilized, and therefore the high degree of distortion may be efficiently generated. Accordingly, freedom is appreciated in the range of distortion utilized for a micro adjustment device so that low voltage drive may be conducted.
