摘要： PROBLEM TO BE SOLVED: To provide a drive amount detection device of a piezoelectric actuator for detecting a drive amount by preventing increase of load without dispensing with addition of a constituent component such as an encoder. SOLUTION: Push pressure applied on a contact part 13 from a rotor 20 is varied by making the rotor 20 eccentric to a rotating shaft and being interlocked with drive of the rotor 20. When the push pressure is varied, the drive amount of the rotor is detected by detecting the change of the amplitude since the amplitude of a detection signal output from a detection electrode 18 of a piezoelectric element is changed to be interlocked with rotation of the rotor 20. Since the encoder, a switch or the like need not be provided, miniaturization of size and thinning are achieved, and consumption current is reduced. COPYRIGHT: (C)2007,JPO&INPIT
摘要翻译：解决的问题：提供一种用于通过防止增加负载而检测驱动量的压电致动器的驱动量检测装置，而不需要添加诸如编码器的组成部件。解决方案：通过使转子20偏心旋转轴并与转子20的驱动互锁而改变从转子20施加在接触部件13上的压力。当推压力变化时，驱动量由于从压电元件的检测电极18输出的检测信号的振幅改变为与转子20的旋转互锁，因此通过检测振幅的变化来检测转子。由于编码器，开关等需要没有提供，实现了尺寸和变薄的小型化，并且消耗电流降低。版权所有（C）2007，JPO＆INPIT
