Image stabilizing apparatus

摘要

In an image stabilizing apparatus in which inner and outer gimbals are pivoted about two pivotal axes so as to fix an erect prism with respect to an inertial system, a torsion coil spring 240 is disposed as one-side stressing means between the inner and outer gimbals 7, 107, so as to pivotally stress the inner gimbal 7 with respect to the outer gimbal 107 in one direction. When image stabilizing control is started, the elastic force of the torsion coil spring 240 instantly changes the angular position of the inner gimbal 7, so that a capacitor is charged earlier, thereby enhancing the response in PWM control.
