Abstract
A lens-fitted photo film unit has an electronic flash device (11, 30; 115) with a printed circuit board (173). The flash device includes a flash-emitting section (6, 170) for emitting flash light toward a photographic field, and a main capacitor (31, 155) for storing charge to be discharged in the flash-emitting section. The printed circuit board converts a current of a battery (12, 127) into a current of high voltage to be supplied to the main capacitor. An LED is driven to emit light in response to charging of the main capacitor at a predetermined level. The flash-emitting section is arranged to be slidably disposed on said printed circuit board.
