Abstract
A pair of iris diaphragms are each connected to a driving pin formed on either free end of a rocking lever at one point and are each supported slidably by a single guide pin formed on a base plate, thereby to move smoothly without wobbling. By driving the rocking lever with a motor, the iris diaphragms move in opposite directions to form an iris aperture for determining correct exposure in fast response to the brightness of a subject to be taken as an image.
