Document Type and Number:
Japanese Patent JP2023110472
Kind Code:
A
Abstract:
To provide a lens cover that is adaptable to interchangeable lenses of various sizes that are fitted to an imaging device, with which it is easy to rotate a zoom ring, and the structure of which is simple.SOLUTION: A lens cover 400 accommodates a lens barrel A200 having a zoom ring 203. The lens cover 400 comprises: a cylindrical stationary tube member 401 which is removably fixed to a camera body 100; a cylindrical movable tube member 410 which is disposed concentrically with the stationary tube member 401; a support unit 440 for restricting the rotation of the movable tube member 410 around an optical axis O100, with respect to the stationary tube member 401, and supporting the movable tube member 410 so as to be movable along the direction of the optical axis O100; and a conversion unit 450 which, when the movable tube member 410 moves along the direction of the optical axis O100, converts the motion in this movement direction to a rotational motion to rotate the zoom ring 203.SELECTED DRAWING: Figure 9
