However, the voice piece type gyro among the ones described in the prior art has a simple structure and is easy to process, but the support structure is difficult and only one angular velocity can be measured. In addition, the ring-shaped vibrating gyroscope has a problem that the angular velocity in two directions can be measured, but the structure is complicated, the support structure is difficult, and the processing is not easy. The gyro can measure angular velocities in two directions, but has a problem that the structure is complicated and it is difficult to balance the vibration balance of each part.

As described above, in the conventional vibration gyro, if it is intended to detect a plurality of angular velocities at the same time, a plurality of gyros must be arranged in the case of the vibration gyro in a single direction, so that the mounting area is small. It becomes wider and economically worse, and the vibration gyro that can measure angular velocities in two directions is difficult to downsize because of its complicated structure and shape.
Therefore, the price reduction could not be expected.

Next, the operation will be described with reference to FIGS. 9, 10 and 11. Drive side arm 27 (28)
(See FIGS. 9 and 11), the driving electrode 29
When an alternating voltage from the oscillator 50 is applied to (31) and 30 (32), expansion and contraction occur near the electrode surface, and contradictory expansion and contraction occur on the two surfaces. This causes bending vibration in the X-axis direction (longitudinal direction). On the other hand, the detection side arm 33 (3
In 4) (see FIGS. 10 and 11), vibration is generated at the same vibration frequency as that of the drive arm 27 (28). At this time, both arms vibrate in opposite X-axis directions.
When this is rotated in the Z-axis direction, Coriolis force is generated and vibration is transmitted in the orthogonal direction (Y-axis direction). Figure 12
FIG. 3 is a waveform diagram showing a state of an electric signal generated in each electrode of the embodiment shown in FIG.
It is a number corresponding to 5 to 42. When the vibration gyro is not rotating, only vibration in the X-axis direction (longitudinal vibration) appears, and when rotating, a vibration in the Y-axis direction (lateral vibration) and a vibration in the X-axis direction (longitudinal vibration) that are proportional to the Coriolis force are combined. The output of the combined vibration appears, and the rotation direction appears as the phase of the vibration (transverse vibration) in the Y-axis direction, which appears as a change in the output of the four electrodes.
