されている。2. Description of the Related Art In recent years, compact silver-salt cameras and electronic still cameras have been made smaller and lighter, and accordingly, a lens cap for protecting the camera lens from water and dust in the outside air has a shutter or barrier for protecting the lens integrated with the camera body. Is often used. Furthermore, if a function of cleaning the taking lens is added to the lens barrier, it is not necessary to carry a lens cleaner or the like, and the camera becomes easier and more compact. For this reason, conventionally, a technique has been proposed in which the taking lens is extended while rotating to come into contact with the lens barrier, and the lens surface is cleaned by rotating the taking lens.

ンズを汚してしまう恐れがある。However, in such a conventional technique, the structure is complicated because it is necessary to extend the taking lens while rotating it. Further, since the lens rotates about the optical axis, cleaning of the center of the lens, which is optically important, is insufficient. Further, since the lens cleaner attached to the lens barrier cannot be removed or replaced, if the lens cleaner becomes dirty, the lens may be contaminated.

The lens cleaner 2 slides in contact with the surface of the imaging lens 3, and the tension increases at both ends of the lens cleaner toward the center along the curved surface of the imaging lens 3, but the leaf spring 4 absorbs the increased tension. The cleaner member always moves while contacting the curved surface of the imaging lens 3 with substantially the same pressure.

In the figure, the lens cleaner 2 is arranged substantially flush with the bottom surface of the image pickup lens 3, and the lens cleaner 2 is opened and closed by opening and closing the lens barrier 1. Moves while closely contacting the surface of the imaging lens 3 as indicated by the chain line in the figure. The tension of the shaft member of the lens cleaner 2 that increases or decreases depending on the curved surface shape of the lens is absorbed by the elasticity of the leaf spring 4 that urges both ends of the shaft member.

可能なため、レンズクリーナの交換が可能となる。As described above, according to the structure and method of the present invention, the cylindrical lens cleaner urged by the lens barrier moves closely to the surface of the image pickup lens, so that the lens has a simple structure. By opening and closing the barrier, the surface of the imaging lens is always cleaned, and it is not necessary to carry another lens cleaner. Further, the image pickup surface of a silver halide camera or an electronic camera is usually a horizontally long rectangle, and the light taken in from the circular lens is not used at all, but only the rectangular portion at the center. With the structure of the present invention, the central portion of this lens is sufficiently cleaned. Furthermore, since the lens cleaner is removable, the lens cleaner can be replaced.
