摘要： The present invention belongs to the field of an image capturing apparatus such as a camera for mobile phone and the like, and has an object to obtain a three axis lens shifting mechanism capable of achieving size reduction and cost reduction with simple structure and an image capturing apparatus equipped with such three axis lens shifting mechanism. A single magnetic circuit exerts an influence of a magnetic field produced by magnets (20) upon active sides of a focusing coil (14) and active sides of coils (10a), (10b). Therefore, movable parts (11+17) can be driven in the direction of optical axis (Z) only by controlling the direction of energizing the focusing coil (14), and further, a first movable part (11) can be driven in a first direction (X) or second direction (direction of rotation) (Y) only by combination of the directions of energizing the coils (10a), (10b). This allows the sharing of the magnetic circuit and an electromagnetic actuator.
摘要翻译：本发明属于诸如用于移动电话的相机等的摄像装置的领域，其目的是获得能够以简单的结构和图像捕获实现尺寸减小和降低成本的三轴透镜移动机构装备有这样的三轴透镜移位机构的装置。单个磁路对由聚光线圈（14）的有效侧和线圈（10a），（10b）的有效侧产生的磁铁（20）产生的磁场产生影响。因此，仅通过控制聚焦线圈（14）的激励方向，可以在光轴（Z）的方向上驱动可动部（11 + 17），此外，第一可动部（11）能够以第一方向（X）或第二方向（旋转方向）（Y）仅通过激励线圈（10a），（10b）的方向的组合。这允许共享磁路和电磁致动器。

摘要： The present invention provides a control device capable of improving hysteresis characteristics of a voice coil motor (31) and attaining a suitable lens position without complicating the structure of the control device. As solving means of the invention, a voice coil motor control device (30) includes a driving current control part (34) that controls a driving current supplied to the voice coil motor (31) in accordance with a driving pulse subjected to pulse width modulation, and a driving pulse control part (32) that divides a drive period of the voice coil motor (31) into a movement period and a holding period, and controls the driving pulse by changing the duty ratio of the driving pulse during the movement period in accordance with a duty setting value and fixing the duty ratio of the driving pulse during the holding period to the duty setting value.

摘要： The driving device includes a bendable shape memory alloy member, a resilient member for applying a tension to the shape memory alloy member in a longitudinal direction thereof, a bending member for bending the shape memory alloy member, and a movable body moved by a displacement of the shape memory alloy member. The bending member contacts the shape memory alloy member, so that the tension is applied to the shape memory alloy member in the longitudinal direction thereof. Compared with the driving device in which the shape memory alloy member is linearly disposed, the decrease in the amount of displacement can be suppressed, so that a space efficiency can be enhanced and the downsizing of the driving device can be accomplished.
