摘要： A camera having a barrier according to the present invention includes a barrier unit in a space between a front main body and a front metal cover serving as an exterior member. Rotation of a barrier driving motor is transmitted to a rotary shaft member passing through the front main body, thereby allowing opening/closing actions of the lens barrier between a protection position for a photographing lens and a lens-barrier retracted position. The front main body is sealed waterproof by an O-ring provided to the outer circumferential surface of the rotary shaft member. With the lens barrel of the camera, rotation of a rotary moving frame is effectively transmitted to a cam frame through a cam follower fit to a linear-action groove, using a circumferential groove and the linear-action groove of a bayonet mechanism.

摘要： A lens barrel permits easier switching of an extending operation between a setup operating region, which begins at a collapsed position where the lens frame of the lens barrel is retracted, and a zooming region, and accordingly provides a simpler mechanism. In the setup operation, a setting gear is driven to extend a setting frame, a float key, and a moving frame so as to extend a first group zoom frame retained on a cam frame and a second lens holding frame from a collapsed position to a photographing standby position. In the zooming operation, a zoom gear is driven to rotationally drive the moving frame so as to adjust the first group zoom frame and the second lens holding frame.
