ABSTRACT:
An iris diaphragm device wherein a rocking motion of a movable magnetic member caused by application of a driving electric current corresponding to the brightness of a subject is transmitted to a leaf operating member for opening or closing iris diaphragm leaves through a connecting lever provided at the both end portions thereof with clearances. Because of the clearances, the iris diaphragm leaves open or close in prompt response to the application of the driving electric current and a chattering motion of the movable magnetic member brought about when it stops is completely absorbed, thereby enable a non-flickering exposure.
