Abstract: In an optical unit with a shake correction function, a first inner-side wall surface disposed on an inner side of a first band-shaped portion of a circuit board in a Y-direction and a second inner-side wall surface disposed on an inner side of a second band-shaped portion of the circuit board in an X-direction are defined in an intermediate-member holder, and a first outer-side wall surface disposed on an outer side of the first band-shaped portion in the Y-direction and a second outer-side wall surface disposed on an outer side of the second band-shaped portion in the X-direction are defined on an outer-peripheral side covering portion. An interval between the first inner-side wall surface and the first outer-side wall surface is smaller than an interval between the second inner-side wall surface and the second outer-side wall surface.

Abstract: An optical unit includes: a reflection portion that reflects an incident light flux incident from outside on a reflection surface in a reflection direction from an incident direction toward an imaging element; a movable body having the reflection portion and a holder supporting the reflection portion; a fixed body; a rotation support mechanism that causes the movable body to rotate with respect to the fixed body with an axial direction as a rotation axis; and a drive mechanism having a magnet and a coil and causing the movable body to rotate with respect to the fixed body. The magnet is provided at a position not contacting the reflection portion in the holder and on a back side of the reflection surface, and has a parallel surface parallel to the reflection surface. The coil is provided at a position opposing the magnet in the fixed body.

Abstract: A shake correction optical unit with a shake correction function may cause a movable body including an optical module to swing around an X axis and a Y axis that are perpendicular to an optical axis L. A flexible printed board may include a second folded portion drawn from the movable body in a +Y direction, and bent in a direction of the optical axis L and folded once; and a first folded portion bent to extend from the second folded portion in the +Y direction and folded once. At least one of the second folded portion or the first folded portion may be thus easily bendable when the movable body swings in either direction around the X axis or around the Y axis.

Abstract: An optical unit with rolling correction function is provided and performs rolling correction by fixing a circuit board on which an imaging element is mounted and a heat dissipating member to a rotation member, transmitting heat from the circuit board to the heat dissipating member, and rotating the rotation member. A rotation shaft of a rotation supporting mechanism is fixed to the rotation member via the heat dissipating member. Accordingly, it is possible to dissipate heat by transmitting heat that is generated from the imaging element, from the circuit board to the heat dissipating member, and then transmitting the heat from the heat dissipating member to the rotation shaft. The imaging element and the heat dissipating member overlap with the rotation shaft at an identical position when the imaging element and the heat dissipating member are seen from an optical axis direction.

Abstract: A drive device is provided and includes: a movable body including an attachment part, to which an optical module is attached; a fixed body; and a support part rotatably supporting the movable body about an optical axis of the optical module attached to the attachment part with respect to the fixed body. 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: The present disclosure provides an optical unit with shake correction function capable of preventing a thrust receiving member, which fixes a sphere, from falling off from the movable body in an optical axis direction. According to some embodiments of the present disclosure, a thrust receiving member to which a first sphere is fixed is held by a holding portion formed of the cutout recess provided in a fixed body. A bottom wall surface of the holding portion makes contact with a bent plate portion of the thrust receiving member from −Z direction side. Further, locked surface parts provided on a pair of side wall surfaces of a holding portion make contact, from +Z direction side, with a pair of locking plate portions protruding from a bent plate portion in circumferential direction in the thrust receiving member.
