    • An angular velocity sensor includes a support body, a retaining portion connected to the support body, first to fourth weights, first to fourth arms, a drive unit for driving the first to fourth arms, and a monitor unit for detecting displacements of the first to fourth arms. An X-axis, a Y-axis, and a Z-axis that are perpendicular to each other are defined. The detector unit is symmetrical with respect to both an axis parallel to the X-axis and an axis parallel to the Y-axis. This angular velocity sensor can cancel an undesired signal caused by external disturbances, such as acceleration or impact, thus detecting an angular velocity accurately.
    • 角速度传感器包括支撑体,连接到支撑体的保持部,第一至第四重量,第一至第四臂,用于驱动第一至第四臂的驱动单元,以及用于检测第一至第四臂的位移的监视器单元 第四臂。 定义彼此垂直的X轴,Y轴和Z轴。 检测器单元相对于平行于X轴的轴线和平行于Y轴的轴线是对称的。 该角速度传感器可以消除由诸如加速度或冲击之类的外部干扰引起的不需要的信号,从而准确地检测角速度。
