ズバリヤ付きカメラ。[Scope of Claim for Utility Model Registration] (1) A front cover of the lens barrel disposed in front of the photographic lens and having a hole for the photographing optical path; a covered position that covers the optical path hole and an uncovered position that does not cover the optical path hole; In a camera with a lens barrier, the barrier is moved from the non-covered position to the covered position, and further moved in the optical axis direction and fitted into the photographing optical path hole of the cover. A camera with a lens barrier, characterized in that it is provided with a barrier driving means for causing the lens barrier to move. (2) The barrier is formed as a stepped disc that integrates a large-diameter disc part and a small-diameter disc part, and the optical path hole is slightly smaller than the large diameter and smaller than the small diameter. The drive means is configured to fit the small diameter disc part of the stepped disc into the optical path hole and urge the large diameter disc part to come into pressure contact with the optical path hole. A camera with a lens barrier as claimed in claim 1 of the utility model registration claim.
