Abstract

An electrostatic supporting type acceleration detecting gyro apparatus is formed as an active type so as to be able to positively cancel a displacement of a gyro rotor. Control DC voltages for generating electrostatic supporting forces and displacement detection AC voltages for detecting a displacement of gyro rotor are applied to electrostatic supporting electrodes, and mechanism control circuits detect displacement indicating voltage signals (P.sub.1A) through (P.sub.4B). A displacement of the gyro rotor and the control DC voltages applied to the electrostatic supporting electrodes are computed based on the displacement detection voltages (P.sub.1A) through (P.sub.4B) outputted from the mechanism control circuits.
