Lens barrel includes first group lens frame unit, second group lens frame unit, lens frame, insertion hole, and depressions. First group lens frame unit holds lenses. Second group lens frame unit holds lens. Lens frame is disposed between first group lens frame unit and second group lens frame unit on an inner circumference side of first group lens frame unit through radial clearance. Insertion hole is provided on an outer peripheral surface of first group lens frame unit, and a jig of lens frame is inserted into insertion hole. Depressions are provided at a position accessible from an outside in a state where first group, second group lens frame units and lens frame are assembled, and fix lens frame to first group lens frame unit.

Lens barrel and method for optical axis adjustment

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 collapsible lens barrel includes: an opening/closing unit (shutter unit) that includes an opening/closing portion (shutter blade) openable and closable along a plane orthogonal to an optical axis to control a light amount, and a maintaining portion (projection) that maintains an opened state of the opening/closing portion; an inner lens disposed closer to an object than the opening/closing unit is; an inner frame that holds the inner lens; an outer lens disposed closer to the object than the inner lens is; an outer frame that holds the outer lens; and a restriction portion that restricts operation of the maintaining portion by restriction applied from the outer frame to the maintaining portion via the inner frame to maintain the opened state of the opening/closing portion when the outer frame and the inner frame are collapsed.

Provided is a collapsible lens barrel including a base barrel, a drive device including a linear motion member reciprocating in an optical axis direction and a drive source for driving the linear motion member, a cam frame provided with a cam groove, a drive device frame that is engaged with the cam groove and causes the drive device to reciprocate in the optical axis direction, a focus lens group frame that holds a focus lens group, and a contact part and an arm that extend from the focus lens group frame toward an object side and are engaged with the linear motion member to cause the focus lens group frame to reciprocate in the optical axis direction.

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.

An imaging apparatus moves a lens in the optical axis direction with respect to the initialization position, and images a subject. The imaging apparatus includes a first lens, a second lens, a driving unit, a first position detection sensor, a second position detection sensor, a third position detection sensor, and a control unit. The driving unit moves the first lens and second lens in the optical axis direction. The first position detection sensor detects the position of the first lens. The second position detection sensor detects the position of the second lens. The third position detection sensor detects the position of the first lens and the position of the second lens. On the basis of the output from the third position detection sensor, the control unit executes the initializing processing of determining the initialization positions of the first lens and second lens.

Imaging apparatus and lens barrel

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.

The lens barrel includes a first supporting frame, an optical element, a second supporting frame, and a guide shaft. The first supporting frame has a first base portion and a first seat portion that projects in a first direction from the first base portion. The second supporting frame supports the optical element and has a first bearing portion. The guide shaft is coupled to the first seat portion and inserted into the first bearing portion. The first seat portion is disposed within the circumference of the guide shaft when viewed in the first 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.

Lens barrel and imaging device with lens barrel

An image stabilizing apparatus of the present invention includes a laminated substratethat has a coil pattern, a hall elementfixed to the laminated substrate, a magnet, a back yoke, an opposing yoke, and a flexible printed circuit board for wiring the coil pattern on the laminated substrate and the hall element, the opposing yokebeing stepped (indentation-type recesses,) in a portion opposing the hall element. Reduction in size, weight and cost are thereby realized in a lens-shift image stabilizing apparatus.
