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.
