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.

摘要： A mirror is fixed at the front of a mirror holder constituting a moving body. First and second coils are attached on the outer circumferential surface of the mirror holder at both sides of a plane passing through the center of gravity of the moving body and parallel to the surface of the mirror. The moving body is rotatably supported by springs so that a rotation axis and another rotation axis orthogonal thereto pass through the center of gravity. Magnets are fixed to a stationary magnet holder to lie at the right and the left sides of the first coil and the upper and lower sides of the second coil. The centers of torque acting on the first and second coils when driving current is applied to the first and second coils are set in the vicinity of the center of gravity and the supporting point of the springs.

摘要： Apparatus for recording opto-magnetically information on an opto-magnetic record medium in the form of the direction of the magnetization stored in a magnetic layer including an objective lens for projecting a laser light beam onto the magnetic layer of the opto-magnetic record medium, a device for generating a bias magnetic field which is applied to the magnetic layer in a direction perpendicular thereto, a supporting device for supporting the objective lens movably in a focusing direction parallel to an optical axis of the objective lens as well as in a tracking direction perpendicular both to the optical axis and an information track direction, and a driving device for moving the objective lens in the focusing and tracking directions to perform the focusing and tracking control. The driving device includes a magnetic circuit for generating a driving magnetic field and focusing and tracking coils mechanically coupled with the objective lens, portions of the focusing and tracking coils being inserted into the driving magnetic field to generate forces for moving the objective lens in the focusing and tracking directions. The magnetic circuit is so constructed that a magnetic flux leaked out of the magnetic circuit becomes minimum in a region of the opto-magnetic record medium onto which the laser light beam is focused by the objective lens, so that the leakage of the magnetic flux does not affect the bias magnetic field and thus the recording operation.
