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.
