发明名称 Slit shutter blade stabilizing device for cameras
摘要 A camera shutter having an aperture, shutter opening blades which travel from a position covering the aperture to a rest position uncovering the aperture to initiate exposure, and shutter closing blades which travel from a position away from the aperture to a position covering the aperture to terminate exposure, and a shutter blade stabilizing device. The stabilizing device includes an elastic member for frictionally pressing at a leading portion of the shutter opening blades at which the driving force is applied to the blades, when the blades are at the rest position, and a member for pressing against the shutter opening blades at a trailing portion of the blades at a portion where the driving force is applied, when the shutter opening blades are at the rest position. The elastic member and the member for pressing together prevent movement of the shutter opening blades when they are at the rest position.
