An operating apparatus is utilized in a photographic device, and includes a base frame, a rotating seat, and a moving seat that carries a pop-up flash unit thereon. The rotating seat and the moving seat are disposed within a first accommodating chamber in the base frame. When a starter button is operated, the rotating seat rotates from a first position to a second position, where the rotating seat projects from the base frame. The moving seat moves away from the rotating seat from a retracted position to an extended position during rotation of the rotating seat. As such, the flash unit is transformed from a non-projected position to a projected position so as to increase the distance between the flash unit and a lens and thus the light distribution angle of the flash unit, thereby improving the photographic quality of the photographic device.
