    Abstract: A retention mechanism includes a fixed part including a magnet, and a movable part opposed to the fixed part. A plurality of rolling elements are provided between the fixed part and the movable part, and the movable part is movable in a plane direction. A magnetic material which forms, in combination with the magnet, a magnetic spring is provided on the movable part. The magnetic spring generates a magnetic attraction force which attracts the movable part to the fixed part. The magnetic material is extended along a direction in which magnetic poles of the magnet are arrayed.

A magnetic material which forms, in combination with the magnet, a magnetic spring is provided on the movable part. The magnetic spring generates a magnetic attraction force which attracts the movable part to the fixed part.

    Abstract: An imaging apparatus includes a shake correction unit, a pixel shift unit, and a controller. The shake correction unit includes a first movable unit and a first position detector, and moves the first movable unit based on outputs of a shake detector and the first position detector. The pixel shift unit includes a second movable unit and a second position detector, and makes a pixel shift correction by moving the second movable unit based on an output of the second position detector. The controller controls the shake correction unit to stop a center of the lens and held by the first movable unit at a position that matches the optical axis. The controller sets a gain for amplifying the output of the first position detector when performing shake correction to be higher than a gain for amplifying the output of the first position detector when making a pixel shift correction.
