Abstract
A flashlight emitting device for a camera wherein the flash coverage of a flash device is varied, only when a mode in which flashlight is to be emitted is selected, in response to a zooming operation to assure appropriate exposure and eliminate wasteful consumption of power. The device comprises flashlight emitting means, mode changing over means operable in response to operation of a manually operable member for selecting one of a first mode in which daylight photographing is to be performed and a second mode in which the flashlight emitting means may be rendered operative to effect flashlight photographing, exposure controlling means for effecting exposure control in accordance with a selected mode, driving means for varying the flash coverage of the flashlight emitting means between a tele side and a wide side in response to a variation of the focal length of a lens of the camera, and driving controlling means for rendering the driving means inoperative when the first mode is selected by the mode changing over means but enabling operation of the driving means when the second mode is selected by the mode changing over means.
