る、ズームストロボ。[Claims for Utility Model Registration] A case includes a xenon tube and a reflector that are arranged to be movable in the optical axis direction behind a lens, and by bringing the xenon tube and reflector closer to the lens. , in a zoom strobe that can obtain a wide irradiation angle and a relatively narrow irradiation angle by separating the xenon tube and reflector from the lens, the reflector is surrounded along the inner periphery of the lens. A reflective frame with a reflective surface on the inner surface is provided, and when the xenon tube and the reflector are moved backward from the lens, the light that does not directly reach the lens out of the light emitted from the reflector is reflected by the reflective frame. A zoom strobe characterized by a reflection surface provided on the inner surface of the flash toward the lens.
