Abstract:
An angular rate detecting device comprising:an oscillation portion connected to a substrate via a supporting member and oscillatable over the substrate in directions of an X-axis and a Y-axis, the X and Y axes being perpendicular to one another;a drive portion causing the oscillation portion to oscillate independently along the X-axis, the drive portion comprising a plurality of sectional drive portions spaced apart in the direction of the Y-axis, the sectional drive portions being capable of oscillating the oscillating portion independently in the direction of the X-axis;a detection portion detecting oscillation of the oscillation portion with respect to the substrate in the direction of the Y-axis; andan angular rate detector for detecting, based on oscillation of the oscillation portion in the direction of the Y-axis, an angular rate that is effective around a Z-axis, the Z axis being perpendicular to both the X-axis and the Y-axis, with the oscillation portion oscillating in the direction of the X-axis.
