リミング機構付きカメラ。[Scope of Claim for Utility Model Registration] (1) A photographic lens, an aperture that defines a photographic screen, and an aperture that is movable in the optical axis direction of the photographic lens and that blocks harmful light during normal photographing. The light shielding member is moved to a harmful light cutting position, and to a screen trimming position closer to the aperture, which limits the luminous flux diameter of the subject light incident from the photographing lens and changes the photographing screen size during trimming shooting. A camera with a screen trimming mechanism. (2) In a pillow-barrel camera that is equipped with a photographic lens, an aperture that defines the photographic screen, and a lens barrel that is stored within the main body when not in use and extends to a predetermined position when in use, Between the photographic lens and the aperture, it is extended out together with the lens barrel during normal shooting to block harmful light during shooting, and is fixed near the aperture during cropping to monitor the luminous flux diameter of the subject light incident from the photographic lens. A camera with a screen trimming mechanism characterized by being provided with a light shielding member that limits and changes the size of the photographic screen.
