To miniaturize a film unit with lens while avoiding a red-eye phenomenon.

A light emitting part unit 42 integrated with a stroboscopic light emitting part 6 is disposed freely movably between a housing position where it is housed within the contour of a unit main body so as to make the film unit with a lens 1 compact and a projecting position where it projects to the outside of the contour of the unit main body. A switch for charge constituted of a metallic armature for short-circuit and a printing contact is disposed between the unit 42 and the printed circuit board of a stroboscopic unit, and it is turned on at the projecting position of the unit 42 and turned off at the housing position thereof. A liquid crystal diaphragm plate is provided at the back of a photographic lens 4, and a diaphragm aperture is set to F9.4 at the projecting position of the unit 42 and is set to F11.8 at the housing position thereof.
