Abstract: An optical move apparatus includes a drive magnet held by a holding member and configured to drive the holding member together with a drive coil in first and second directions, a first guide member fixed to the holding member, a second guide member configured to guide the first guide member in the first direction, and a third guide member fixed to the base member and configured to guide the second guide member in the second direction on a side opposite to the first guide member in the optical axis direction. None of the first, second, and third guide members overlap the drive coil in the optical axis direction. The third guide member includes two bodies in a plane orthogonal to the optical axis direction. At least part of the third guide member is thinner than the drive coil in the optical axis direction.

Abstract: A lens barrel includes a first cam member including a first cam portion engaged with a first lens holding member, the first cam member being configured to rotate and to move the first lens holding member, and a second cam member including a second cam portion engaged with a second lens holding member, the second cam member being configured to rotate around the optical axis to move the second lens holding member in the optical axis direction via the second cam portion. A third engagement portion provided on one of the first lens holding member and the second cam member is engaged with a third cam portion provided on the other. The second cam member is rotated, and moved in the optical axis direction by the third cam portion.

Abstract: A lens barrel which prevents an increase in driving force for optical units in a direction of an optical axis to downsize a power transmission mechanism, save power and also prevents undesired movement of the optical units even when they are urged by urging forces large enough to prevent rattling. The optical units move in the direction of the optical axis, and they are urged by urging member in the direction of the optical axis. A camshaft provided on outer peripheries of the optical units extends in the direction of the optical axis and is cam-engaged with each of the optical units. The power transmission mechanism transmits driving force, which is for rotating the camshaft, to the camshaft. A torque generated in the camshaft by the urging member urging one of the optical units and another torque generated in the camshaft by the urging member urging another one of the optical units are opposite in direction.

Abstract: An image pickup apparatus capable of maintaining accuracy of positioning a sealing member and also applying a proper elastic repulsion force to an image pickup device. A first holding member holds an image pickup device, a first optical member is disposed forward of the device in a first direction orthogonal to an image pickup surface of the device, and a sealing member is sandwiched and held between the first optical member and the device. The first holding member has an opening portion for guiding light flux having passed through a photographing optical system to the device, and an abutment surface brought into contact with part of the first optical member. The sealing member has protrusions each extending forward in the first direction, along an outer shape of the first optical member inside the opening portion of the first holding member, as viewed in the first direction.

Abstract: An image pickup apparatus includes a vibration device configured to generate a vibration to transmit to a user a touch sense in response to an operation of a user on an operation unit, and a grip portion gripped by the user. A lens barrel is attached to a front surface side of the image pickup apparatus. The grip portion covers a rear surface side and the front surface side of the image pickup apparatus. The grip portion that covers the front surface side of the image pickup apparatus includes a protrusion portion. The vibration device is disposed inside the protrusion portion and on a side facing an optical axis of the lens barrel.

Abstract: In a lens barrel, a first drive unit is driven to thereby cause a third lens holding frame to be movable in an optical axis direction relatively to a first lens holding frame and a second lens holding frame. One end of a guide shaft is fixed to the first lens holding frame, and another end of the guide shaft is fixed to the second lens holding frame.
