  • Publication number: 20220350106
    Abstract: Provided is a lens barrel including: a fifth lens unit barrel; a fourth lens unit barrel; a linear ultrasonic motor configured to electrically drive the fourth lens unit barrel in an optical axis direction; a rack configured to transfer a driving force of the linear ultrasonic motor to the fourth lens unit barrel; a rack spring configured to bias the rack so that the rack is brought into contact with the fourth lens unit barrel; and a rack guide shaft. The rack guide shaft is fixed to the fourth lens unit barrel. The fourth lens unit barrel and the rack move together in the optical axis direction. When the fifth lens unit barrel is brought into contact with the fourth lens unit barrel, a relative position of the fourth lens unit barrel and the rack in the optical axis direction changes against a biasing force of the rack spring.

  • Publication number: 20220342229
    Abstract: An image stabilizing apparatus includes a driver configured to drive an optical system configured to correct an image blur in a direction that includes a component in a direction orthogonal to an optical axis, detectors configured to detect position information on the optical system, and a controller configured to control the driver. The detectors are disposed at a first detecting position and a second detecting position on a plane orthogonal to the optical axis. At the first detecting position, position information in a first detecting direction and position information in a second detecting direction different from the first detecting direction are detected. At the second detecting position, position information in a third detecting direction is detected. At least two of the first to third detecting directions are orthogonal to each other.
