A lens barrel includes at least one lens, the optical axis of the lens; the first frame (the fixed frame) having the first restricting portion () and having an approximately cylindrical shape about the optical axis; the second frame () having the cam groove () and having an approximately cylindrical shape about the optical axis; the third frame () having the guide portion () which restricts inclination thereof with respect to the first contact portion () and the optical axis and having an approximately cylindrical shape about the optical axis; the drive arm () having a cam follower (), the second restricting portion () and the second contact portion (), 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 () for guiding the guide in a movable manner in the optical axis direction; and the spring (). The first restricting portion engages with the second restricting portion. The cam engages with the cam groove (). 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.

Lens barrel

A lens barrel includes a filter ring retainer, an OIS base frame, and a ring-shaped filter ring. The filter ring retainer has a male screw. The OIS base frame has a female screw locking the male screw. The ring-shaped filter ring has an inner circumferential projection inserted into between the filter ring retainer and the OIS base frame, and is disposed on the outer circumferential side of the filter ring retainer and the OIS base frame.

A lens barrel according to a first aspect of the present disclosure includes the lens frame which holds the lens, and the holding frame which holds the lens frame in a state where the lens frame is movable in a plane orthogonal to the optical axis. A biasing means which generates a force in the direction that the lens frame is lifted up against the gravity is provided to at least the holding frame out of the holding frame and the lens.

A lens barrel includes a fixed frame, a rotary frame provided inside the fixed frame, a first frame provided inside the rotary frame, an electronic component provided inside the first frame, and a flexible printed circuit board connected, at one end thereof, to the electronic component and connected, at the other end thereof, to the fixed frame. A gear part is provided at an outer circumferential surface of the rotary frame. In the first frame, a first protrusion outwardly protruding beyond the gear part in a radial direction about the optical axis is provided at a position corresponding to the flexible printed circuit board in a circumferential direction about the optical axis on a side of the gear part opposite to the object in the optical axis direction.

A flexible printed circuit according to the present invention is anchored to a holding member disposed within electronic equipment, and comprises: a main body portionthat includes electrical lines; a first connection portiondisposed in the main body portionand to which an electric component or another flexible printed circuit is connected; and a first cover portionformed as part of the main body portionand disposed so as to cover the first connection portion. Part of the first cover portion is held by a lens holder. According to this configuration, an insulated state can be reliably maintained by using a configuration in which soldered connection portions are covered by part of the FPC and the covering portion is held by the housing.

Flexible printed circuit, image pickup device, and electronic equipment

A lens barrel includes a holder, a lens frame, and an elastic member. The holder includes a first guide axis and a second guide axis. The lens frame includes a first guide section which is movably fitted around the first guide axis and a second guide section which is movably fitted around the second guide axis, and retains at least one lens. The elastic member exerts an energizing force on the second guide section and is disposed between the holder and the second guide section. The lens frame moves along the optical axis direction of the lens as the first guide section is guided by the first guide axis. The elastic member energizes the lens frame along the optical axis direction of the lens by exerting an energizing force on the second guide section. The distance from the holder to the second guide section is different from that from the holder to the first guide section.
