The movable body includes a movable body-side fixing part, to which a flexible printed circuit pulled out of the optical module is fixed. The fixed body includes a fixed body-side fixing part, to which the flexible printed circuit is fixed. And, a portion between the movable body-side fixing part and the fixed body-side fixing part in a region along an outer periphery of the fixed body is set as a region drawn around in an attitude causing a thickness direction of the flexible printed circuit to be directions both orthogonal to a direction of the optical axis.

Abstract: A movable unit of an optical module having an image shake correction function is supported by a gimbal mechanism so as to be rotatable around a first axis R1 and a second axis R2. The movable body is driven by a shake-correction magnetic drive mechanism including magnets and fixed to the movable body. The movable body further includes a lens-moving magnetic drive mechanism to move a lens module in an optical axis direction. The lens-moving magnetic drive mechanism includes a lens-moving coil fixed to the lens module 7 and a lens-moving magnet disposed radially outward of the lens-moving coil. The magnets and also serve as the lens-moving magnet and are disposed radially outward of a triaxial intersection.

Abstract: An optical unit with a shake correction function includes a movable body, a gimbal mechanism, a fixed body and a magnetic drive mechanism. The gimbal mechanism includes a gimbal frame, a first connection mechanism turnably connecting the movable body with the gimbal frame around a first axis, and a second connection mechanism turnably connecting the fixed body with the gimbal frame around a second axis. The first connection mechanism includes a first spherical body, a first spherical body fixing part to which the first spherical body is fixed in one of the movable body and the gimbal frame and, in the other, a first spherical body support part having a first concave curved face which faces the first spherical body fixing part and contacts with the first spherical body, and the first spherical body fixing part has a first fixing hole to which the first spherical body is partly fitted.

Abstract: An optical unit having a shake correction function may include a movable body including an optical module; a fixed body that supports the movable body in a swingable manner; a swing drive mechanism that includes a magnet and a coil forming a magnet-coil pair, with a counterpart of the magnet-coil pair being fixed to the movable body and another counterpart to the fixed body, and swings the movable body relative to the fixed body; a magnetic detection sensor that detects a magnetic field of the magnet; and a magnetic member that returns the movable body to an original position by a magnetic attraction force with the magnet. The magnetic detection sensor overlaps the magnetic member as viewed in a direction orthogonal to a thickness direction of the magnetic member.

Abstract: In an optical unit with shake correction function, a first stopper mechanism configured to define a swinging range of a movable member is composed of: a first projection part for stopper and a second projection part for stopper, both of which are provided in a camera module; and a projection portion (abutment target) of a holder bottom plate member. Therefore, when the first projection part for stopper and the second projection part for stopper; and the projection portion of the holder bottom plate member abut against each other and then movement in the Z axis direction of the movable member is restricted, the camera module does not move in the Z axis direction any more. Accordingly, the camera module does not slip off from a camera module holder of the movable member.
