<P>PROBLEM TO BE SOLVED: To provide a gyro module allowing detection of three-axis angular velocity. <P>SOLUTION: The three-axis gyro module 10 comprises a first gyro element piece 12, a second gyro element piece 14, and a third gyro element piece 110 having two detection axes respectively; a first operational circuit 112 subtracting output signals of the second gyro element piece 14 and the third gyro element piece 110 and outputting it; a second operational circuit 114 adding output signals of the second gyro element piece 14 and the third gyro element piece 110 and outputting it; and a third operational circuit 116 calculating output signals of the first gyro element piece 12 and the first operational circuit 112 and outputting it. The extending directions of the first detection axis of the first gyro element piece 12, the first detection axis of the second gyro element piece 14, and the first detection axis of the third gyro element piece 110 are coincident; and the extending directions of the second detection axis of the first gyro element piece 12 and the second detection axis of the second gyro element piece 14 are intersecting with each other. <P>COPYRIGHT: (C)2010,JPO&INPIT |
