Zusammenfassung:	PURPOSE:To attain cost reduction, to miniaturize a camera and to reduce weight the by allowing a single motor to drive a lens barrier opening, closing, and driving system and a lens switching and driving system for varying. CONSTITUTION:The driving force of a motor 7 is selectively switched and connected to the opening, closing and driving system of a lens barrier 58 or a lens switching and driving system by a planet gear mechanism 10 as a clutch means in accordance with the normally or reversely rotating direction of the one motor 7. Therefore, only the motor 7 can be used both as the actuator of the opening, closing and driving system of the lens barrier 58 and as that of the lens switching and driving system, and serves as the actuator to drive both driving systems. Thus, cost reduction is attained, an overall camera is miniaturized and its weight is reduced.
