Abstract:
1. A vibrating gyroscope comprising: a substrate; a vibrator including at least a pair of vibrating bodies, in which both end portions in a longitudinal direction are fixed together in the width direction by intermediate parts, and the vibrator is constructed such that a secondary bending vibration with both ends movable in a thickness direction of the vibrating bodies is generated; a driver making the vibrating bodies generate buckling vibrations in opposite directions relative to each other; and a detector for detecting the magnitude of the secondary bending vibration of the vibrator; wherein the resonance frequency of the secondary bending vibration is close to the resonance frequency of the buckling vibration; and the vibrator is arranged such that major surfaces of the at least a pair of vibrating bodies extend in a plane that is substantially perpendicular to a major surface of the substrate.
