PROBLEM TO BE SOLVED: To enable accurate vibration detection irrespective of the application attitude of an optical apparatus, while miniaturization is realized. SOLUTION: This equipment is provided with earth magnetism detectors 11p, 11y detecting the direction of earth magnetism, first vibration detecting means 12p, 12y, 13p, 13y, 14p, 14y (which function when 11pa, 11ya are selected by 16p, 16y) detecting vibration from a relative angle between the direction of detected earth magnetism and the optical axis direction of an optical apparatus, and second vibration detecting means 12p, 12y, 13p, 13y, 14p, 14y (which function when 14pa, 14ya are selected by 16p, 16y) detecting vibration from the value corresponding to the displacement of a mass part which displacement is caused by applying an inertia force or a gravitational force. As the mass part of the second vibration detecting means, the earth magnetism detectors 11p, 11y installed in the first vibration detecting means are used. |
