Abstract
A shutter device loaded in a fixed focus camera for making soft-focus photograph includes a swingable shutter drive member and two shutter blades for opening and closing a shutter opening. When the shutter drive member swings in response to photographing operation, the shutter blades rotate oppositely to each other such that the shutter opening gradually appears. While opening, the shutter blades continuously form a small stop. After a flashlight is emitted during forming the small stop, the shutter blades rotate moreover and the shutter opening is entirely exposed. Then the shutter blades close to cover the shutter opening entirely.
