A partition plate having a group of blades and a mapping window between the leading blade group and the rear blade group, and a covering plate on the opposite side of the partition plate from the main plate so as to sandwich the blade group located therebetween. In the focal plane shutter, at least a gap formed between the partition plate and the base plate or the cover plate includes a surface for collision braking the leading blade above or below the window, and a surface for collision braking of the leading blade in the height direction of the window. A spacer is provided with a vertical portion that also serves as a braking surface for the rear blade, and the partition plate is rearwardly moved onto the collision surface of the spacer so that the rear blade collides with the spacer at the end of exposure. A focal plane ivy characterized by having a convex portion that guides the tip of the blade.
