Abstract
PURPOSE: To provide the device of smooth opening and closing operations by letting two sheets one set of shutter blades integrally forming the photo detecting aperture be opened and closed by an operating pin which operates in the position closer on the line connecting the centers of exposure opening and photo detecting window.
CONSTITUTION: Movable habits of each mechanical element are shown by arrows in the figure. The first position where the operating pin 16d of the opening and closing lever 16 driving two sheets one set of shutter blades 26, 27 integrally forming the photo detecting iris holds the shutter blades 26, 27 fully closed and the second position where it fully opens these exist between the center of an exposure opening 1a and the center of a photo detecting window 1b and on the line connecting both centers. Arrangement is so made that on the way of moving from the first position to the second position it assumes arc motion from the turning center of the opening and closing lever 16 and therefore the oepning and closing operations are smoothly accomplished. Furhter with this construction, the use of those of the same shape symmetrically on the front and back for two sheets of the shutters 26, 27 is an advantage.
