摘要： PROBLEM TO BE SOLVED: To ensure a sufficient area on the root of a vibrating chip, make it possible to arrange a vibration detecting element these, and improve the detecting efficiency, by detecting exciting vibration for stabilization of excitation and vibration due to Coriolis force in the direction perpendicular to the exciting vibration, with the same vibration detecting element. SOLUTION: When vibrating chips 3, 4 are excited in X-axis direction by a driving circuit 131 and rotated at an angular velocity Ωaround an axis in parallel to Y-axis as the center, vibration in Z-axis direction whose amplitude is in proportion to the angular velocity Ω is generated. This vibration amplitude appears on electrodes 34, 36, 45, 48 for detection as change of charges, and is detected by a detecting circuit 132, offset-corrected by an offset correct circuit 134, and converted in a DC signal by a synchronous detection circuit 135. Then the angular velocity Ω is calculated. During the above operation, change of charges corresponding to exciting amplitude also appears on the electrodes 34, 36, 45, 48 for detection, and is detected by the detecting circuit 132, and fed-backed to a driving circuit 131 via an AGC circuit 133, thereby stabilizing the exciting amplitude.
