Title:
ローリング用磁気駆動ユニットおよび振れ補正機能付き光学ユニット
Document Type and Number:
Japanese Patent JP6934319
Kind Code:
B2
Abstract:
To provide a rolling magnetic driving unit that can be employed for both of an optical unit with shake correction function that causes an optical module to swing and rotate and an optical unit with shake correction function that causes the optical module to rotate, a second unit (i.e., a rolling magnetic driving unit) includes: a rotation seat; and a fixation member that supports the rotation seat via a bearing mechanism. The rotation seat and the bearing mechanism configure a rotation-supporting mechanism. The rotation-supporting mechanism supports a holder, which supports the optical module such that the optical module is able to swing, such the holder is able to rotate on the axis. Furthermore, the second unit includes a rolling magnetic driving mechanism, which includes a rolling driving coil that is held by the rotation seat and a rolling driving magnet that is held by the fixation member.
