Abstract
A foldable diffuser for flash units mounted on photographic cameras and mechanism by which such a diffuser is moved automatically between collapsed and erected positions with respect to a flash unit mounting receptacle. The diffuser is pivoted on an axis normal to the front face of a shutter housing in a collapsible camera such that it lies against the front face in the folded position and swings out over a side face of the shutter housing in front of a flash unit mounted on the side face in the erected position. Movement to the collapsed position is effected by the erecting linkage of the camera against a pivotal bias on the diffuser.
