Abstract
An improved operating device for a camera provided with a flash device which cooperates with the camera for flashlight photographing when the light emitting portion is brought to a position above the camera and suitable for flashlight photographing and with an operation device for bringing the light emitting portion to said position for flashlight photographing. The improved operation device comprises, a detecting circuit which produces an output when the brightness of the object is lower than a predetermined value; operation apparatus for receiving the output from the detecting circuit and bringing the light emitting portion to the position for flashlight photographing; and a detecting system for detecting the output voltage from a power source of the flash device and inhibiting said operation apparatus from operating when said detected source voltage is lower than the value necessary for flashlight photographing.
