振れ補正機能付き光学ユニット
Document Type and Number:
Japanese Patent JP7453099
Kind Code:
B2
Abstract:
To reduce the floating of a coil with respect to a coil installation surface of a flexible printed substrate in an optical unit with a shake correction function.SOLUTION: An optical unit 1 with a shake correction function comprises: a magnetic drive mechanism 10 for shake correction, which swings a movable body 5 around a first axis R1 and around a second axis R2; and a magnetic drive mechanism 13 for rolling correction, which swings the movable body 5 around an optical axis. A flexible printed substrate 15 to which coils of the magnetic drive mechanism 10 for shake correction and the magnetic drive mechanism 13 for rolling correction are fixed includes a coil installation surface 157 on which a coverlay film 15b is arranged on a surface of a flexible base material 15a and a recess-shaped portion 158 on which the coverlay film 15b is not arranged on the surface of the flexible base material 15a. A winding start side coil wire 101 let out from an inner peripheral portion of each coil is housed between each coil and the recess-shaped portion 158.SELECTED DRAWING: Figure 13
