Abstract: 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.

Abstract: A shutter having two groups of shutter blades. One group of shutter blades opens the shutter and a second group of blades closes the shutter. A shutter-opening actuation member releasably locked by a locking pawl when the shutter is cocked, actuates the shutter-opening group of shutter blades for taking an exposure. A shutter-closing actuation member releasably locked by a second locking pawl actuates the shutter-closing group of shutter blades for completing the taking of an exposure. An electromagnet in an exposure control circuit is energized during the taking of an exposure and deenergized to control the exposure time and terminate the exposure. A control member that controls the release of the control member by its locking pawl is biased by a single spring.

Abstract: A camera shutter having a plurality of shutter blades operable from a shutter-closing operative position to a shutter-opening operative position and back to the shutter-closing operative position. An opening driving lever and a closing driving lever are provided for operating the shutter blades to their operative positions. A rebound preventing arrangement is provided by providing pins fixed on the opening and driving levers and making provision on a cocking lever for holding the driving levers from rebounding upon reaching their terminal operating positions in activating the shutter blades in opening and closing the shutter. The pins on the driving levers are engaged at these terminal positions by the locking lever and releasably held to preclude rebounding thereby to preclude rebounding of the shutter blades.
