摘要： A lens driving apparatus for driving a movable body in a focus direction and a tracking direction is provided with: a holder, to which a focus coil, a tracking coil and a lens are installed, to thereby constitute the movable body; and a magnetic circuit for applying magnetic fluxes to the focus coil and the tracking coil, to thereby drive the movable body in the focus direction and the tracking direction. The tracking coil includes two sets each having upper and lower two coils arrayed in the focus direction such that the two sets are arrayed in the tracking direction. The magnetic circuit applies the magnetic fluxes opposite to each other along a jitter direction, with respect to the upper two coils and the lower two coils without applying the magnetic fluxes with respect to portions adjacent to the upper and lower two coils.

摘要： This camera actuator comprises: an optical path bending member; a lens unit disposed at a subsequent stage of the optical path bending member; a first actuator that is disposed near the optical path bending member and displaces the optical path bending member; and a second actuator and a third actuator that are disposed near the lens unit so as to be apart from each other in a first direction, and that respectively displace the lens unit in a second direction and a third direction that are orthogonal to the first direction and orthogonal to each other. As a result, the present invention provides a camera actuator capable of improving the degree of freedom of design around the optical path bending member.

摘要： An objective lens driving device is provided with an objective lens; a lens holder for holding the objective lens; a pair of linear suspension springs for supporting the lens holder at each one end; a spring holder whereupon the other ends the springs are fixed; and a driving means for at least driving the objective lens in a tracking direction together with the lens holder. The linear suspension springs have narrowed or widened end compared with the other end in plan view from an optical axis direction. The lens holder is supported to be driven in the tracking direction, by having the cross point of the two lines, which pass the suspension spring ends on one side and are vertical to the extending directions of the linear suspension springs, respectively, at the driving center.

摘要： A magnet used for an actuator of an optical pickup has a magnetization pattern with two different pole areas adjacent each other. At a corner part defined by the boundary line of the two pole areas, the pole area inside the corner part has a projection area, projecting in the direction of the pole area outside the corner part. Owing to the existence of the projection area, insufficiency of the magnetic flux density at the corner part particularly close to the vertex can be improved so that a desirable magnetic field can be provided to the printed coil substrate disposed in the vicinity of the magnet.

摘要翻译： 用于光学拾取器的致动器的磁体具有彼此相邻的两个不同极区域的磁化模式。 在由两个极区域的边界线限定的角部，角部内的极区域具有在角部外侧的极区域的方向上突出的投影区域。 由于存在投影区域，所以可以提高特别靠近顶点的角部处的磁通密度的不足，从而可以对设置在磁体附近的印刷线圈基板提供期望的磁场。

摘要： A stopper 30 includes a projected portion 35 for restricting movement of a movable section in a focusing direction and a wall section 34 for restricting movement of the movable section in a tracking direction, the projected portion 35 and the wall section 34 being integrally formed from a synthetic resin. With the arrangement, a single stopper 30 can simultaneously restrict the movements of the movable section both in the focusing direction and the tracking direction and determine its movable ranges. Accordingly, unlike conventional arrangements, discrete stoppers for the focusing direction and the tracking direction do not have to be provided, thereby reducing the number of components and cost as well as facilitating mounting operation. In addition, even when a strong impact is applied, the stopper will not be deformed.
