案登録請求の範囲第１項記載の装置。[Claims for Utility Model Registration] (1) An opening/closing ring provided on the front side of the lens barrel, and a spring that biases this opening/closing ring in one rotational direction to bias the dust cover to the closed or open state. and an opening/closing ring rotation means for opening or closing the dust cover biased to the closed or open state by rotation of the opening/closing ring, wherein the opening/closing ring rotates from the opening/closing ring. the opening/closing ring rotation means is in contact with the opening/closing ring rotation arm and rotates the opening/closing ring in a direction opposite to the biasing direction of the opening/closing ring biasing spring means. It consists of an opening/closing ring operating member and a circular plate that moves this operating member.This circular plate has a pattern that encodes data such as the focal length or magnification of a plurality of lenses, and the pattern data is transmitted to the camera control device. The lens is formed by an encoder plate configured to send the lens to a specified position, and the encoder plate is driven by a driving means for moving a lens disposed on a lens barrel to a designated predetermined position. Camera dust cover opening/closing device. (2) The opening/closing ring operating member includes a first lever whose tip abuts an arm of the opening/closing ring to press the arm, and a first lever whose tip abuts a pin of an encoder plate and rotates the encoder plate. a second lever that is moved; a shaft that pivots the other ends of both levers so that the distance between the tips of the levers can be changed; a first spring provided around the shaft for biasing both levers so as to maintain a distance between the tips of the levers at a constant length, and integrally formed by the first spring and the shaft; and a second spring that biases the first and second levers connected to the arm so that the tip of the first lever does not come into contact with the arm. .
