Abstract: 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.

Abstract: A camera system and a lens barrel are provided in an exchangeable-lens camera including a shake correction mechanism that integrally drives a lens barrel and an imaging unit, it being possible for lenses to be exchanged smoothly, and greater utility and convenience to be obtained. A lens barrel to and from which a camera body can be attached and detached, wherein the lens barrel includes: a first barrel having a first engagement part that engages with a first part of the camera body; a second barrel disposed inside the first barrel, the second barrel having a second engagement part that engages with a second part of the camera body, and having an optical system; and a drive unit that drives the second barrel in relation to the first barrel.

Abstract: A lens barrel includes a first frame, a second frame rotatable with respect to the first frame, an urging member held by one of the first frame and the second frame, and a moving member that is disposed to be movable in optical axis direction and transfers an urging force of the urging member to the another one of the first frame and the second frame.

Abstract: A camera system and a lens barrel capable of improving practicality and convenience by enabling smooth lens exchange in a lens-interchangeable camera having a vibration correction mechanism that integrally drives a lens barrel and an image capturing unit. A lens barrel to which a camera body can be detachably attached, the lens barrel including: a first barrel having a first engaging portion that engages with a first portion of the camera body; and a second barrel disposed inside the first barrel and having an optical system and a second engaging portion that engages with a second portion of the camera body.

Abstract: A lens assembly includes a first lens holder that holds a first lens, a first guiding shaft that guides the first lens holder in a parallel direction to an optical axis of the first lens, a first driver that drives the first lens holder in an axial direction of the first guiding shaft, a second lens holder that holds a second lens that is different from the first lens, and a second driver that drives the second lens holder in a direction of the optical axis. Here, the first guiding shaft, the second driver, and the first driver are arranged in the stated order in a circumferential direction of a circle that is centered on the optical axis.

Abstract: To decrease operating noise of actuators in a lens barrel, provided is a lens barrel comprising a first optical member that moves in an optical axis direction prior to image capturing and during image capturing; a first drive member that causes the first optical member to move in the optical axis direction during image capturing; a second optical member that has the first drive member fixed thereto, moves in the optical axis direction prior to image capturing, and is fixed at a position in the optical axis direction during image capturing; and a second drive member that causes the second optical member, the first optical member, and the first drive member to move in the optical axis direction prior to image capturing. Also provided is an image capturing apparatus comprising the lens barrel and an image capturing section that captures image light from the lens barrel.

Abstract: A transport mechanism for an optical disc cartridge capable of discharging an optical disc cartridge to a predetermined position by making a transport roller in pressure contact with the optical disc cartridge even if the cartridge is erroneously inserted. A guide arm is rotatively mounted which projects into an optical disc cartridge transport path between the transport roller and a disc insertion port. If the optical disc cartridge is inserted in a normal orientation, the guide arm is rotated by the optical disc cartridge to rotate the arm in the clockwise direction to allow the optical disc cartridge to be inserted, whereas if the optical disc cartridge is inserted in an orientation rotated by 90° from the normal orientation, the transport roller is made in pressure contact with the side wall of the optical disc cartridge.
