に９いて説明する。On the other hand, a vibrating gyroscope (Japanese Patent Application Laid-open No. 85420/1983) has been proposed that detects angular velocity from the Coriolis force that occurs when an angular velocity is generated by vibrating an object without using rotational force. This vibration gyroscope can be considered as a vibration sensor having a tuning fork structure. The prototype of this structure can be found in US Pat. No. 2,554,646. According to this, the rectangular plates of the driving elastic body (for excitation) and the sensing elastic body are
” (With a tightened and orthogonal joint, the velocity (V) is 1.
This detects the Coriolis force acting on the elastic body for V-shaped detection. A conventional angular velocity sensor will be described below with reference to the drawings.
