<p>PROBLEM TO BE SOLVED: To provide a compact imaging device that is excellent in a tremor-resistance performance.SOLUTION: An imaging device causing a front lens in front of a reflection element of a front lens group located on an object side to be operative and to suppress an image tremor on an imaging plane comprises: a movable frame that holds the front lens; a supporting member that fixedly holds the reflection element; and a supporting mechanism that supports the movable frame relative to the supporting member in a manner capable of spherically oscillating around a point on an axis extending the optical axis of the front lens in the reference state to a rear side of the reflection surface of the reflection element; a permanent magnet and coil that serve as an actuator giving the movable frame drive force according to a tremor applied to an imaging optical system and causing the movable frame to spherically oscillate. The permanent magnet and coil are formed into a flat shape having a planar expanse in a direction parallel with a tangent plane of a spherical body centering around a fulcrum of the spherical oscillation, and a normal line of the tangent plane along which the permanent magnet lies is set to have an inclination away from the optical axis of the front lens as advancing to the object side.</p> |
