機構。[Claims for Utility Model Registration] (1) In a camera barrier mechanism in which a pair of barriers for opening and closing the aperture are pivotally attached to a lens cover tube having an aperture on the front surface, A camera barrier mechanism is characterized in that it is connected by a link that opens and closes symmetrically at all times. (2) Spring means for biasing the pair of barriers in the opening direction is coupled to one of the pair of barriers or the coupling link, and one of the pair of barriers or the coupling link is coupled to resist the spring means. 2. The camera barrier mechanism according to claim 1, further comprising a force applying portion that applies a force to close the barrier. (3) The lens cover tube is supported so that it can be moved in a straight line between the photographic position and the storage position behind it, and the lens cover tube is supported on its outer periphery so that as it rotates, the lens cover tube can be moved between the photographic position and the storage position. Claim 2 further comprising: a cam ring for moving the lens cover, and a barrier closing member provided between the cam ring and the force applying part for applying a barrier closing force to the force applying part in the storage position of the lens cover tube. Barrier mechanism of the camera described.
