An apparatus that transfers an optical element includes: a driving unit that generates a driving force in response to an external signal, a rotating plate that rotates due to the driving unit, a first deceleration unit that is rotatably in frictional contact with the rotating plate, a rotating shaft that has an outer screw surface and that rotates by being mated to the first deceleration unit, an intermediate plate that is rotatably in frictional contact with the first deceleration unit, a second deceleration unit that is rotatably in frictional contact with the intermediate plate, a transmission unit that transmits an external rotational force to the second deceleration unit, and a moving unit that supports the optical element and that is engaged with the outer screw surface of the rotating shaft and moves with the rotating shaft as the rotating shaft rotates.

Apparatus for transferring optical element

Provided is a digital photographing apparatus that includes a lens unit frame having an opening through which light enters from a forward direction, and having a lens unit to be disposed inside the frame, or having a lens barrel comprising a lens unit to be disposed inside the frame; and a lens unit base disposed at a rear of the frame so as to be coupled to the frame, wherein the frame comprises a first opening through which a printed circuit board (PCB) emerges from the inside of the frame to the outside of the frame, and wherein the frame and the lens unit base are disposed to form a gap therebetween, thereby forming a second opening corresponding to the gap through which a PCB emerges from the inside of the frame to the outside of the frame.

Digital photographing apparatus with lens unit configured for flexible printed circuit boards having different lengths

There is provided a device for transferring an optical element including: a differential transmitter including an intermediate ring rotatably with respect to a housing and having a plurality of openings on its circumference, first decelerating members rotatably inserted into ones of the openings, a first transmitting ring disposed on one side of the intermediate ring to contact the first decelerating members, and a second transmitting ring disposed on an opposite side of the intermediate ring; a driving element generating a driving force to rotate the first transmitting ring; a manual manipulation ring transmitting a rotation force generated due to manual manipulation to the second transmitting ring; a moving portion that supports the optical element and moving along the direction of an optical axis; and a cam rotating due to connection with the intermediate ring and having a cam groove connected with the moving portion.

Device for transferring optical elements

A lens barrel and a photographing apparatus including the lens barrel include a clutch assembly disposed on a plane orthogonal to an optical axis between a manual adjustment ring and a distance adjustment ring. The clutch assembly rotates on a fixing part of the lens barrel and includes first, second, and third clutch wheels and one or more rollers, wherein the first clutch wheel includes an operator disposed on an end thereof and that receives a rotation force of the manual adjustment ring, the second clutch wheel is disposed on an inner surface of the first clutch wheel, the third clutch wheel is disposed on an inner surface of the second clutch wheel and fixed to the distance adjustment ring, and the rollers are radially disposed with respect to the optical axis and comprise surfaces contacting the operator and other surfaces contacting an outer surface of the third clutch wheel, wherein the first and second clutch wheels are elastically fixed to each other by first elastic members, a second elastic member is disposed between the second clutch wheel and the fixing part, and a third elastic member is disposed at both ends of the second clutch wheel, supports ends of circumferential surfaces of the rollers, and controls positions of the rollers.
