Abstract
In a device for adjusting the tilt angle of an optical pickup by using a leaf spring and tilt-angle adjusting screws, an actuator is mounted on and supported by a spherical seat of an optical base . One portion of a base of the actuator is resiliently pressed by a leaf spring . Tilt-angle adjusting screws and are provided which are respectively screwed in two threaded holes and in the base . The direction of the resiliently pressing force imparted to the actuator by the leaf spring is tilted with respect to axes of the tilt-angle adjusting screws and . By forming the leaf spring into a substantially U-shaped configuration, the resiliently pressing force applied to the actuator is made uniform.
