Claims

[Scope of Claim for Utility Model Registration] In a camera equipped with a focal plane shutter that has a viewfinder section that serves as an optical path for the photographer to confirm the subject, an aperture that is adjacent to the viewfinder section and that serves as the optical path during photographing. a substrate having a window, and a slit-forming blade and cover that are divided into a plurality of pieces and are spread over the window to shield the window from light, and overlapped in a storage section on the substrate to open the window. a group of blades including a blade; a first arm whose main body is rotatably supported on the substrate and whose other end supports at least the slit-forming blade; and a first arm whose main body is rotatably supported on the substrate; movably supported and forming a parallel link with the first arm;
A second arm that supports at least the slit-forming blade and at least one of the first and second arms forms a parallel link, is disposed on the side facing away from the window, and supports the cover blade. and a third arm that supports the first and second arms for the slit-forming blade, in a state where the blade group is superimposed on the storage section located on the finder side of the substrate. A blade support portion for a covering blade located in a region restricted by the window and the finder and arranged at least adjacent to a slit-forming blade of the blade group in the third arm is not located in the restricted region. A blade support device for a focal plane ivy characterized by the following features.
