Abstract: A lens barrel includes at least one lens, the optical axis of the lens; the first frame (the fixed frame 900) having the first restricting portion (901, 902) and having an approximately cylindrical shape about the optical axis; the second frame (1000) having the cam groove (1036) and having an approximately cylindrical shape about the optical axis; the third frame (510) having the guide portion (511) which restricts inclination thereof with respect to the first contact portion (514) and the optical axis and having an approximately cylindrical shape about the optical axis; the drive arm (520) having a cam follower (523), the second restricting portion (524, 525) and the second contact portion (526), and having an approximately arcuate shape constituted of a portion of a circular cylinder about the optical axis or an approximately plate shape; the guide shaft (601) for guiding the guide in a movable manner in the optical axis direction; and the spring (603). The first restricting portion engages with the second restricting portion. The cam engages with the cam groove (1036). The drive arm moves approximately parallel to the optical axis due to the relative rotation of the second with respect to the first frame, the third is biased by the thus bringing the first contact portion and the second contact portion into contact with each other, and the third frame moves in the optical axis direction in an interlocking manner with the drive with the inclination of the guide being restricted by the guide.

Abstract: A lens barrel in which a lens can be moved in a direction parallel to an optical axis includes: a first frame having a cam follower and a cam follower base that holds the cam follower; and a second frame that has a cam groove engageable with the cam follower. The first frame and the second frame are moved relatively to each other along the optical axis. The cam follower base has a first end connected to the main body of the first frame via at least one thin portion, and a second end not connected to the main body. The thin portion is formed such that a thickness of the thin portion in a radial direction of the lens barrel is smaller than that of the cam follower base.

In the first state, a first cam follower is guided by a first cam. In the second state, the first cam follower is guided by the first cam, and a second cam follower is guided by a second cam. In the third state, the second cam follower is guided by the second cam. In the third state, at least part of the first cam follower enters a space formed by a recess portion or a hole portion.

Abstract: A lens barrel includes a support frame and a retracting lens frame. The support frame includes a main body portion, a first linking portion and a second linking portion. The first region is configured to dispose the second lens in the imaging enabled state. The second region is formed continuously with the first region. The first linking portion links the second region on one side of the main body portion in the optical axis direction. The second linking portion links the second region on the other side of the main body portion in the optical axis direction. The retracting lens frame is disposed between the first linking portion and the second linking portion in a housed state.

Abstract: A lens barrel includes a first lens, a second lens, a first frame body, a second frame body, and a retracting lens frame. The retracting lens frame is configured to move so that a position of the second optical axis of the second lens changes from a position on the first optical axis of the first lens to a position that is outside the first optical axis, during the transition period between the imaging enabled state and the housed state. A contact portion is formed on the inner peripheral part of the first frame body. A protrusion of the retracting lens frame is configured to engage with and guided by the contact portion during movement of the retracting lens frame. The thickness of a region constituting the side wall of the contact portion is increased over the thickness of the other region toward the inside of the cylindrical part.

Abstract: An aperture unit (20) comprises an aperture cover (22), an aperture base (27), and a light shielding portion (24). The aperture cover (22) has an opening (22a) through which light passes. The aperture base (27) is disposed on the downstream side of the aperture cover (22) in the light incidence direction, and has an opening (27a) through which light passes. The light shielding portion (24) is disposed between the aperture cover (22) and the aperture base (27), and has an opening (24d) through which the light that passed through the opening (22a) passes, and a plurality of opaque aperture stop blades (24a, 24b, 24c) that are formed from a polyimide resin and vary the size of the opening (24d).
