In a flash built-in camera, a movable lens barrel is movable between a collapsed
position of being contained inside a camera body, and photographing positions in
front of the collapsed position, and holds a taking lens. A flip-up flash emitting
unit is movable between a contained position and a flashing position, and when
in the flashing position, applies flash light to a photographic field. A motor
drives the movable lens barrel and the flash emitting unit. One transmission mechanism
connects the movable lens barrel and the flash emitting unit with the motor, and
responds to motion of the motor in a predetermined direction, to move the movable
lens barrel to a photographing position and to move the flash emitting unit to
the flashing position. The transmission mechanism includes one ring-shaped gear
disposed about the movable lens barrel.
