ABSTRACT:
An electronic programmed shutter has a sector which is also used as an aperture vane, a sector opening and closing lever normally biased in the sector closing direction, a driving member which is moved in a linear direction by a release operation of the shutter, an electromagnetic device for controlling the closing time of the shutter by an electronic switching circuit, and a driving lever having a first cam face acting in such a direction as the sector is opened by the sector opening and closing lever and a second cam face coacting with the electromagnetic device. The driving level is movably supported on the driving member such that the sector opening and closing lever is rotated by the driving force of the driving member via the driving lever to effect opening of the sector and the cooperative relation between the sector opening and closing lever and the driving lever is released by the electromagnetic device to effect closing of the sector by the normal bias applied to the sector opening and closing lever.
