Embodiment approach
[0221] (Structure of the magnetic drive mechanism for hand shake correction)
[0222] In the above-mentioned embodiments, a structure is adopted in which either of the first hand-shake correction magnetic drive mechanism 250x and the second hand-shake correction magnetic drive mechanism 250y is located on the side of the movable body, that is, the movable module One side holds shake correction coils (shake correction coils 230x, 230y), and the fixed body 210 side holds shake correction magnets (shake correction magnets 240x, 240y). However, it is also possible to employ a structure in which one of the first hand-shake correction magnetic drive mechanisms 250x and the second hand-shake correction magnetic drive mechanism 250y is movable on the side of the movable body. The hand shake correction coil is held on the module 1 side, the hand shake correction magnet is held on the fixed body 210 side, and the other hand shake correction magnetic drive mechanism is held on the movabl...
other Embodiment approach
[0332] The above-mentioned embodiment is an example of a more preferable aspect of the present invention, but is not limited thereto, and the present invention can be variously modified and implemented within the scope without changing the gist of the present invention.
[0333] In the above-described embodiment, the shake correction magnet 21 is attached to the cover member 9 , and the shake correction coil 23 is attached to the housing 116 . Alternatively, for example, the shake correction magnet 21 may be attached to the casing 116 and the shake correction coil 23 may be attached to the cover member 9 . In this case, the center CL3 of the shake correction coil 23 is arranged below the contact surface 27 of the shake correction stone 21 . That is, the center CL3 of the shake correction coil 23 is arranged at a position closer to the fulcrum portion 119 than the magnetic force center of the shake correction magnet 21 in the optical axis direction.
