PURPOSE: To obtain an oscillation gyro which can detect the rotational angular speed accurately while removing the harmonic components relatively easily. CONSTITUTION: An oscillator 12 comprising detection pieces 16a, 16b and a driving piece 16c is included in the side face of an oscillator body 14. Output signals from the detection pieces 16a, 16b are amplified while being inverted by means of inverted amplifier circuits 24, 26. Output signals from the inverted amplifier circuits 24, 26 are shaped by means of a comparator circuit 32. Output signals from the comparator circuit 32 are passed through a phase correction circuit 34 and applied to the driving piece 16c. Output signals from the inverted amplifier circuits 24, 26 are also fed to a differential circuit 38 while delivers an output signal to a synchronous detection circuit 40. The synchronism detection circuit 40 detects the output signal from the differential circuit 38 in synchronism with the comparator circuit 32. |
