PURPOSE:To reduce cross coupling by a simple and inexpensive constitution, by providing a ferromagnetic substance on a production of a rotating shaft of a rotor of a follow-up type gyroscope. CONSTITUTION:An iron piece 6 is fixed onto a base 5 being on an extension of a rotating shaft 2 of a rotor 1. When the rotating shaft 2 of the rotor 1 has deflection angle against the cylindrical center shaft of a coil 4, a relative distance between the iron piece 6 and both N and S poles of the rotor 1 is varied, synchronizing with rotation of the rotor 1. Since the rotor 1 is rotated around the rotating shaft 2 at a high speed, a perturbation movement is generated in the right angle direction against mean attraction force, by attraction force of both the poles of the rotor 1 and the iron piece 6, and its direction is reverse to that of cross coupling caused by inductance of the coil 4. In this way, cross coupling is reduced by a simple and inexpensive constitution. |
