VIBRATION GYRO ELEMENT, GYRO SENSOR, AND ELECTRONIC APPARATUS |
摘要 |
A vibration gyro element includes drive vibrating arms and detection vibrating arms at the opposite side, and has a first detection mode in which the drive vibrating arms flexurally vibrate oppositely to each other in an out-of-plane direction in an opposite phase to an action direction of Coriolis force and the detection vibrating arms flexurally vibrate oppositely to each other in the out-of-plane direction in an opposite phase to that of the drive vibrating arms, and a second detection mode in which the drive vibrating arms flexurally vibrate oppositely to each other in the out-of-plane direction in the same phase as the action direction of the Coriolis force and the detection vibrating arms flexurally vibrate oppositely to each other in the out-of-plane direction in the same phase as that of the drive vibrating arms.
