Abstract

A lens-fitted photo film unit has an electronic flash device with a flash circuit board. The flash device includes a flash-emitting section for emitting flash light toward a photographic field, and a main capacitor for storing charge to be discharged in the flash-emitting section. The flash-emitting section and main capacitor together constitute a flasher/capacitor unit. In one embodiment, a detachable connector, providing both the electrical connection and the mechanical support, connects the flasher/capacitor unit to the flash circuit board. In another embodiment, a securing portion comprising a pair of rails disposed on the flasher/capacitor unit, secures the flasher/capacitor unit to the flash circuit board, where the rails ride along opposite sides of a projecting portion of the flash circuit board.
