Lens-fitted photo film unit with flash device and method of flash lighting thereby

   
   

An intensity of a flashlight projected from a flashlight projector is at the maximum outside a photographic area. A plate protuberance is formed in a center of an inner face of a protector. A part of the flashlight emitted from a flash tube is reflected on upper and lower faces of the plate protuberance so as to tend into the outside of the photographic area. The intensity of the flashlight emitted into a center of the photographic area is deflected on a wedge of an end of a plate protuberance. Thus, distribution pattern of the flashlight is changed by the plate protuberance, and the intensity of the flashlight becomes 1.0-1.5 LV smaller in the center of the photographic area than on upper and lower limits thereof. A main subject in a smaller distance is not overexposed, and a background in a larger distance is not underexposed.
