ABSTRACT:
In an instant, self-developing, and folding camera, a built-in flash unit is disabled as long as the camera is folded. According to another aspect, the flash is disabled after each photograph until the feed motor that drives the film during development has completed its operation. A collapsible bellows forms a dark space between first and second housing sections. When the bellows are folded the flash is drawn to the first section by coupling means. When the bellows are extended the coupling means draws the flash into an operative position.
