Vibration type inertial force detection sensor and electronic device using the same

摘要

A vibration type inertial force detection sensor, which includes a vibrator, a drive unit for vibrating the vibrator, a detection unit for detecting distortion generated in the vibrator by the inertial force, and a drive unit and a detection in a normal state. A power supply unit that supplies power to the unit and supplies power to either the drive unit or the detection unit and does not supply power to either the drive unit or the detection unit in the power saving state. .
