    Abstract: A stereoscopic image pickup apparatus includes: a fixed barrel; a moving frame that is positioned in the fixed barrel so as to be advanceable and retractable and holds a plurality of moving lenses in a parallelly provided manner; and an actuator positioned in a space formed between the fixed barrel and the moving frame in a direction orthogonal to a line connecting photographing optical axes of the plurality of moving lenses and configured to drive the moving frame along the photographing optical axes.

    Abstract: An optical unit includes: a fixed portion configured to hold at least one of an object side fixed lens group and an image side fixed lens group; a movable portion configured to hold a movable lens group between the object side fixed lens group and the image side fixed lens group; and a voice coil motor configured to relatively move the movable portion with respect to the fixed portion in a direction of a central axis, the voice coil motor including a coil arranged on the fixed portion, and magnets magnetically polarized in directions orthogonal to the central axis and substantially symmetrical with respect to the central axis. At least two magnets adjacent to each other in a circumferential direction in a cross section orthogonal to the central axis are arranged so as to be shifted in opposite directions in a circumferential direction.

    Abstract: An optical unit includes: a cylindrical fixing member configured to retain at least one of an object-side fixed lens group and an image-side fixed lens group; a cylindrical movable member configured to retain a movable lens group between the groups and arranged on a radial-direction inner side of the fixing member slidablly with respect to the fixing member, the cylindrical movable member having a same central axis as the cylindrical fixing member; a voice coil motor including: a coil arranged in the fixing member; and magnets arranged on the movable member and magnetically polarized in a direction intersecting with the central axis, the voice coil motor being capable of moving the movable member relative to the fixing member along a direction of the central axis; and a rotation restricting member configured to restrict rotation of the movable member about the central axis with respect to the fixing member.
