摘要： 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.

摘要： An exposure control device for a camera, having a first light receiving element for sensing light beams reflected from a film surface and a second light receiving element for sensing light beams from an object before taking a photograph. In this arrangement an auxiliary diaphragm, which is opened as a shutter is closed and is closed as the shutter is opened, is provided in front of the second light receiving element. The first and second light receiving elements are connected in parallel between input terminals of an operational amplifier for the light measuring. Accordingly, an exposure control with a high degree of accuracy is effected based on an output of the light measuring operational amplifier.
