摘要： According to one aspect of the present invention, a focal plane shutter of a camera for conducting TTL multi-pattern light adjustment is provided that comprises a plurality of shielding blades for covering an aperture in a developed position. Each of the shielding blades has at least one edge thereof overlapped by one of the shielding blades immediately adjacent thereto in the developed position, the overlapped edge having a predetermined minimum overlap width. Each of the shielding blades has the lens-side surface thereof formed to be light-reflective having a rate of diffused reflection. The rate of diffused reflection is set within a range according to the predetermined minimum overlap width, such that TTL multi-pattern exposure is enabled and light leakage between the shielding blades does not occur.

摘要： The present invention aims at improving the durability of a very high-speed shutter exceeding 1/8000 sec and further attaining a very high shutter speed even with sectors composed of a material exhibiting a low rigidity. For this purpose, a focal plane shutter device comprises: first and second blinds each constructed of a plurality of sectors; and a light shielding plate having an opening and an intermediate plate disposed between the first blind and the second blind. The first and second blinds are run in the facial direction of the light shielding plate so as to cover and expose the opening. The light shielding plate and the intermediate plate are bonded, or a shock absorbing member is interposed between these two plates.
