ABSTRACT:
An acceleration detection gyro apparatus is of the electrostatic supporting type. This gyro apparatus can be made inexpensive, long in life, excellent in durability and can be applied to a wide variety of fields. A gyro rotor (20) is supported relative to a gyro case (21) by an electrostatic supporting force in a non-contact fashion and rotated about the spin axis along the Z axis by a rotor driving system. The gyro rotor (20) is disk-shaped and constructed by forming metal thin film electrodes on both surfaces of a plate member made of preferably an insulating material. The gyro apparatus includes a slave control system for slaving a displacement of the gyro rotor (20) relative to the gyro case (21) in the Z-axis direction (spin axis direction) and a central position control system for slaving a displacement of the gyro rotor (20) in the X-axis and Y-axis directions.
