Abstract

PURPOSE: To obtain accurate exposure information through simple operation by disposing one optical panel slidably in the optical axis direction at the front face of a light emitting part.
CONSTITUTION: A light emission radiation angle variable hood 9 provided with a diffusion panel 10 being an optical panel is disposed, slidably in the optical axis direction, to the front face of the light emitting part 8 consisting of a reflecting shade, flash discharge tube, etc. Then, in the wide angle state that the diffusion panel 10 and the light emitting part 8 front face are approached, the 1st index of object distance index being the 1st exposure information 12 and the aperture value being the 2nd exposure information 15 become visible through the display window 20 of the 3rd display plate 17 having film sensitivity being the 3rd exposure information 18. On the other hand, in the telephoto state that the diffusion panel 10 is spaced apart from the light emitting part 8 front face, the 3rd index of the 1st exposure information 12 positions below the display window 19 and in a standard standard stated, the 2nd index of the 1st exposure information 12 is visible from the display window 20.
