ABSTRACT:
A vibrating gyroscope includes: a column-shaped vibrating body; driving elements formed on side-faces of the vibrating body, for exciting a bending vibration in the vibrating body; detection elements formed on side-faces of the vibrating body, for detecting changes in the bending vibration of the vibrating body; pseudo-Coriolis force generating elements formed on side-faces of the vibrating body, for applying a force to the vibrating body in the same direction as that of a Coriolis force generated when a rotational angular velocity is produced about the vibrating body; and a pseudo-Coriolis signal generating circuit for supplying the pseudo-Coriolis force generating elements with a pseudo-Coriolis signal to apply a force in the same direction as that of the Coriolis force to the vibrating body.
