Abstract

A lens barrel assembly that is attached to and detached from a camera includes: a lens barrel, which surrounds a lens and includes an inlet through which an external light enters; and an outlet through which light, which has passed through the lens, exits; a rotating unit, which is attached to the lens barrel such that the rotating unit rotates in a circumferential direction of the lens barrel; a shield plate, which has a first side rotatably connected to the rotating unit and a second side rotatably connected to the lens barrel and moves between a position of closing the outlet and a position of opening the outlet as the rotating unit rotates; and a driving unit, which contacts the camera when the lens barrel is attached to the camera, generates rotation force from friction force, and rotates the rotating unit.
