Abstract:
A lens-fitted photo film unit comprising:a taking lens including at least a front lens and a rear lens; a larger-stop plate provided with a larger stop and disposed at either of positions, one of which is between the front and rear lenses and the other of which is behind the rear lens; a shutter blade being rotatable between a closed position where an exposure aperture is closed, and an open position where the exposure aperture is opened; and a stop-changing plate being rotatable between a smaller-stop position where a smaller stop is inserted into an interval of the front and rear lenses, and a larger-stop position where the smaller stop is evacuated from the interval of the front and rear lenses, wherein rotational centers of said shutter blade and said stop-changing plate are arranged in either state of coincidence and approximation, and a rotational direction of the shutter blade from the closed position to the open position is set to be identical with a rotational direction of the stop-changing plate from the smaller-stop position to the larger-stop position.
