Electronic flash and lens-fitted photographic film unit including the same

摘要

An electronic flash comprises a housing provided with a light flash projecting window and incorporating a flash lamp assembly with its associated control circuit including a capacitor therein and an external casing enclosing the housing. The casing has at least an opening or part defined by and torn off along a perforated line to form an opening for exposing the light flash projecting window. The electonic flash with or without the external casing can be attached to a disposable lens-fitted film unit with a simple exposure member. The external casing is provided with an opening or part defined by and torn off along a perforated line to form an opening, or a flexible part defined by an incised line, for allowing a charge switch to be depressed from outside the external casing so as to charge the capacitor.
