摘要： An optical pick-up for reading information recorded on an optical record carrier as tracks including a light source emitting a light beam, a collimator lens for converting the light beam into a parallel light beam, a swingable tracking mirror for reflecting the parallel light beam, an objective lens for projecting the light beam reflected by the tracking mirror onto the record carrier, and a plano-parallelo plate arranged rotatably between the collimator lens and the tracking mirror. The plano-parallelo plate is rotated in accordance with the rotation angle of the tracking mirror such that the light beam reflected by the record carrier propagates along the same light path as that along which the light beam is made incident upon the record carrier and any off-set in the tracking error signal can be removed.

摘要： In an optical switch according to the present invention, a galvo plate is caused to abut against a base plate on its mount portions at the both ends, and in addition, abutting sections formed at portions near galvano-mirrors are also caused to abut against the base plate. As a result, heat transfer from the galvo plate to the base plate is improved, and heat in the galvano-mirrors, particularly heat in its drive circuit and heat due to a laser, can be dissipated to the base plate. This allows the implementation of multi-channelization in which a plurality of optical path changing elements are arranged with ease and high-accuracy, and also facilitates the heating of the optical path changing elements.

摘要： An optical element supporting device has one ends of two parallel plate springs, which are extended in a tangential direction, fixed to a holder, has the other ends thereof fixed to a fixture member, and has a collimator lens locked in an opening of the holder. A base fixed to the bottom of the fixture member has two yokes formed thereon. Magnets each polarized in two directions are fixed to the insides of the yokes. Coils are fixed to two surfaces of the holder opposed to the magnets. A target is fixed to the holder, and a sensor is fixed to the bottom of the base. When a current flows into the coils, electromagnetic force is produced along an optical axis due to the interaction between the coils and the magnets opposed to the coils. This causes the parallel plate springs to loosen. Consequently, the holder, target, collimator lens, and coils move as a whole along the optical axis.

摘要： A terminal portion as a plate-like attachment portion is formed on a spring made of a plate material supporting a movable member. These portions are molded integrally at the center plane of the fixed member. Deformation due to temperature changes or external forces is prevented by bending rigidity in the surface direction of the terminal portion. This deformation is arranged to be symmetrical deformation with respect to the center plane as a center, which is the terminal portion. In this manner, the rigidity of the movable member is increased to prevent deformation and to improve the precision.
