Patent number: 11733478Abstract: A lens barrel is removeably attachable to an image pickup unit, wherein a large amount of shake can be corrected. This lens barrel includes a mounting part that is removeably attachable to an image pickup unit, including: an image forming optical system that forms a subject image for the image pickup unit; a support unit that supports at least a portion of the image forming optical system; and a fixed unit that is disposed outside of the support unit and that is fixed to the mounting unit. The support part is relatively rotatable and moveable with respect to the fixed unit, about at least two axes which are substantially orthogonal to the light axis of the image forming optical system.Type: GrantFiled: September 14, 2020Date of Patent: August 22, 2023Assignee: NIKON CORPORATIONInventors: Koji Nagaoka, Kunihiko Shimizu, Teppei Okuyama, Noriyasu Kotani, Hisanori Togawa

Publication number: 20230152675Abstract: An accessory mount can be inserted through the camera body mount without any of the first through third tabs being hindered by any of three camera body-side tabs at the camera body mount, as long as the accessory mount is inserted into the camera body mount at a correct interlock phase. The first, second, and third tabs extend over varying lengths along the circumferential direction. The first tab extends over a greatest length and the third tab extends over a smallest length, along the circumferential direction. The accessory mount includes a restricting member, a fitting portion, and a lock pin hole. The restricting member is disposed at a position assumed on a side substantially opposite from the lock pin hole across the fitting portion.Type: ApplicationFiled: January 20, 2023Publication date: May 18, 2023Applicant: NIKON CORPORATIONInventors: Masanori HASUDA, Noriyasu KOTANI, Hideaki HOSHIKAWA

Patent number: 11513306Abstract: An interchangeable lens is removably attached to a camera body including a body-side mount, an image sensor, body-side terminals and a first to fourth body-side claws. The interchangeable lens includes the lens-side mount, lens-side terminals which are in contact with body-side terminals, a first to fourth lens-side claws engaged with the first to fourth body-side claws once the interchangeable lens is attached to the camera body. The first and third lens-side claws are disposed on a third lens-side line intersecting with the first lens-side line at an optical axis with approximately 45 degrees. The first lens-side line passes through a center between opposite ends of the first lens-side claw to the optical axis. The second and fourth lens-side claws are disposed on a fourth lens-side line orthogonal to the third lens-side line at the optical axis.Type: GrantFiled: October 25, 2018Date of Patent: November 29, 2022Assignee: NIKON CORPORATIONInventors: Koji Nagaoka, Noriyasu Kotani

Patent number: 11054605Abstract: An interchangeable lens is removably attached to a camera body including a body-side mount, body-side terminal group above an upper side of an image sensor and a first to fourth body-side claws. The second body-side claw extends in circumferential direction with a center angle and is located outside the body-side terminal group. The interchangeable lens includes the lens-side mount, lens-side terminal group, a first to fourth lens-side claws engaged with the first to fourth body-side claws in proper attachment of the interchangeable lens. The four body-side claws are disposed in four regions divided by first and second body-side lines in relation to the arc-shaped body-side terminal group. The interchangeable lens is inserted to the camera body and rotated by a first angle for attaching and the terminals of the camera body and the interchangeable lens are connected. The center angle of the second body-side claw is smaller than the first.Type: GrantFiled: October 25, 2018Date of Patent: July 6, 2021Assignee: NIKON CORPORATIONInventors: Koji Nagaoka, Noriyasu Kotani
