摘要： A light-shielding blade for use in cameras utilizes a film of para-type aromatic polyamide for its base material. The light-shielding blade has a single-layer structure using an aramid film as its blade material. The film is added with carbon black at a ratio of 2 to 10 percent by weight relative to a total weight of the blade material. Alternatively, the light-shielding blade has a laminated structure with a plurality of aramid films stacked each other and having a thickness of 2 to 30 microns each, a total thickness being set to a range of 50 to 200 microns.

摘要： A focal-plane shutter for digital still cameras includes a first blade and a second blade, each having a plurality of arms and at least one blade component pivotally supported thereby; a driving member for the first blade, opening an exposure aperture through the first blade; a driving member for the second blade, closing the exposure aperture through the second blade; a retaining means for the first blade and a retaining means for the second blade, retaining individual driving members at positions where the exposure operation is started, immediately before the exposure operation is started, and releasing their retaining forces at preset timing when the exposure operation is started; and a cocking member for actuating the driving member for the second blade when moved from the initial position to the cocked position thereof, and actuating the driving member for the first blade in photography. Consequently, the amount of operation of each of the first blade and the second blade is minimized and a small-sized focal-plane shutter can be constructed.

摘要： A drive member attached to the output shaft of a DC motor placed on a shutter base board includes a drive pin connected to the arm of a shutter blade within a blade chamber for driving the shutter blade to open and close an exposure opening with the reciprocal rotation of the DC motor. A brake member rotatably attached to the shutter base board and having a frictional force applied thereto by a spring washer brakes the rotation of the drive member when a bent portion is pushed by the drive pin to rotate.

摘要： A first driving member for front blade that connects a front blade and a second driving member for front blade are rotatably mounted to a shaft 1g, a rear blade driving member that connects a rear blade is rotatably mounted to a shaft, the first driving member follows the second driving member and is rotated by a biasing force of a set spring in a setting operation, and is pressed by the second driving member and rotated in photography. The restraining means has a restraining member that can go in and out of an operation path of the restrained portion of the first driving member. When the present invention is adopted in a single-lens reflex camera, the restraining member can be within the operation path of the restrained portion in the setting operation for photography using an optical finder, and the restraining member can be outside the operation path of the restrained portion in the setting operation for photography using an electronic finder.

摘要： The forcal plane shutter for cameras is equipped with a first release lever capable of retaining a rear blade group at position to close an exposure aperture, and a second release lever capable of maintaining a front blade group and the rear blade group at the unfolded position thereof and the folded position thereof respectively until the front blade group and the rear blade group are attracted and retained at the unfolded position and the folded position respectively securely with an electromagnetic device. The focal plane shutter is of a double light interruption type which has excellent response to the release signal and capable of assuring stable operations. The focal plane shutter further comprises a control means capable of retaining the first release lever in the released state thereof and can be set in a successive photographing mode accordingly.
