ABSTRACT:
A lens-fitted photo film unit has photo film pre-contained in a photo film containing section (14, 70). An exposure is taken on the photo film via a photographic light path (20). An electronic flash device (16) is secured in front of the photo film containing section. The electronic flash device includes a circuit board (27, 69) having a flash circuit, a flash-emitting section, and a charge switch for charging the flash circuit. The charge switch includes two contact points (32a, 32b, 69a, 69b) and a movable switch segment (33, 68a) for contact with the contact point to switch on charging of the flash circuit. A front cover (18, 60, 91) is secured to cover a front of the circuit board. The switch segment is depressible for coming in contact with the contact point. An operable lever (12, 63, 94) is associated with the front cover in rotatable fashion between an erected position and a folded position relative to the front cover. The switch segment is kept depressed when the operable lever has the erected position.
