摘要： An optical switch device for driving a movable member mounting a light reflection member thereon by a magnetic drive circuit, wherein, in an optical waveguide switching device (1) as an optical switch device, a movable member (2) mounting thereon an optical waveguide switching prism mirror (2) is driven in an X direction by a magnetic drive circuit while being floated from a fixing-side member (13) in order to improve stability of a light outputting position. When the movable member (2) is moved to a desired position in the X direction, power supply to solenoids (45, 46) is stopped in a clamp mechanism (40), and a clamp plate (41) presses the movable member (2) against the fixing-side member (13) to fix it. A V-groove (30) formed in the movable member (2) and a V-groove (31) formed in the fixing-side member (13) mesh each other to position the movable member (2) in the X direction.

摘要： A lens driving device includes a moving body having a lens and a drive magnet that is moveable with the lens in an optical axis direction of the lens, and a fixed body that moveably supports the moving body in the optical axis direction. The fixed body includes a first drive coil and a second drive coil that are disposed in the optical axis direction and form magnetic circuits with the drive magnet, and a first magnetic member and a second magnetic member that are disposed opposite the first drive coil and the second drive coil, respectively. The moving body is retained at a first position by magnetic attraction working between the drive magnet and the first magnetic member when energization of the first drive coil is stopped. The moving body is also retained at a second position by magnetic attraction working between the drive magnet and the second magnetic member when energization of the second drive coil is stopped.

摘要： A lens driving device includes a moving body equipped with a lens and a driving magnet attached to the lens, and a fixed body that is equipped with a driving coil that forms together with the driving magnet a magnetic circuit and moves the moving body in an optical axis direction of the lens between a first lens retaining position and a second lens retaining position, and at least one magnetic member disposed adjacent to at least one of two end sections in the optical axis direction of the driving magnet. The moving body is retained at the first lens retaining position by magnetic attraction caused by the driving magnet and the magnetic member when energization of the driving coil is stopped. Accordingly, the driving coil does not need to be energized while the lens is retained at the first lens retaining position.

摘要： A rotor for motor may include a rotation shaft, a permanent magnet structured in a tube-like shape and fixed to an outer peripheral side of the rotation shaft, and a sleeve which is structured in a tube-like shape, disposed between an outer peripheral face of the rotation shaft and an inner peripheral face of the permanent magnet, and press-fitted and fixed to the outer peripheral face of the rotation shaft. The sleeve is retreated from an end part of the permanent magnet on one side in an axial direction to the other side in the axial direction so that a first ring-shaped recessed part is formed between the rotation shaft and the permanent magnet and the rotation shaft and the permanent magnet are fixed to each other with a first adhesive in the first ring-shaped recessed part. The rotor may be applied to a motor, preferably to a stepping motor.
