  • Patent number: 12066641
    Abstract: An optical unit with a shake correction function includes a movable module and a fixed body. The movable module has a lens and is supported by the fixed body to be capable of moving in a direction orthogonal to an optical axis of the lens. The fixed body surrounds the movable module from an outer periphery side.

  • Patent number: 11982865
    Abstract: In a unit with shake correction function, a driving magnet and a driving coil which constitute a rolling drive mechanism are arranged on an outer side of a radial direction with respect to a disposition space for an optical module that is provided in a movable body. Therefore, since there is no need to arrange the disposition space and the rolling drive mechanism to be deviated from each other in an optical axis direction, it is possible to make the unit with shake correction function thin in the optical axis direction. Further, in the rolling drive mechanism, since the driving magnet and the driving coil face each other in the optical axis direction, a magnetic field of the rolling drive mechanism does not easily enter the disposition space for the optical module. Consequently, magnetic interference between the movable body and the rolling drive mechanism can be suppressed.

An incident surface on which the light from an outside enters, a reflection surface that reflects light that enters through the incident surface, and an emitting surface through which light reflected on the reflection surface is emitted are formed on the prism. A contact surface to which the reflection surface of the prism contacts, and an adhesive hole in which an adhesive that adheres to the reflection surface of the prism to fix the prism to the prism holder is disposed are formed in the prism holder. The adhesive hole passes through the prism holder.

  • Publication number: 20230384612
    Abstract: In an optical unit with a shake correction function, a cylindrical holder having an inner peripheral side on which a camera module is fixed is composed of metal. In the optical unit with a shake correction function, a case-side protrusion projecting toward the inner peripheral side of a cylindrical case surrounding the outer peripheral surface of the holder is formed on the inner peripheral side of the case. When a movable body moves relative to a fixed body while the optical axis of a camera module tilts the most, portions of the holder farther inside in the optical axis direction than edges formed on the outer peripheral surface of the holder before the edges come into contact with the inner peripheral surface of the case.
