Abstract
A compact camera comprises a flash unit adapted to be flipped up from a camera body for use and flipped down towards the camera body for storage and having a viewfinder opening for viewing a subject to be photographed, and an elongate resiliently flexible supporting part for the flash unit constrained to be flexed longitudinally in opposite directions when the flash unit is flipped up and down to operate as an overcenter spring for urging the flash unit alternatively to flip up or down and having a viewfinder opening arranged to be located behind the viewfinder opening of the flash unit when the flash unit is flipped up. According to the invention, a non-flexible lens element is connected to the flexible supporting part over its viewfinder opening but only at in-line points spaced apart laterally across the supporting part, as opposed to longitudinally along the supporting part, to prevent the lens element from interfering with flexing of the supporting part longitudinally.
