PROBLEM TO BE SOLVED: To prevent a film unit with a lens from being broken or cracked and to prevent a broken piece from being scattered by decreasing the degree of breakage or crack even if the film unit is broken or cracked by providing a rib crossing with a breaking or cracking direction at the low-strength part of an outside cover. SOLUTION: The rib 45 crossing with the breaking or the cracking direction is erected near an aperture 39 on the inner wall surface of the front cover 16 so as to improve strength. Thus, even when an impact is given to the corner part of the cover 16 near the aperture 39, the cover 16 is prevented from being broken and cracked. Even if the cover 16 is broken or cracked, a situation that the broken part is separated from the cover 16 and the main capacitor of a strobe light unit is exposed to the outside is prevented because the strength is improved by the rib 45. Since the rib 45 is formed apart from the upper surface and the side surface of the cover 16, the cover 16 does not partially get thick, and the quality of outside appearance is not degraded due to shrink.
