ABSTRACT:
An optical system shifting device for a camera in which an optical system is shifted in the direction of the optical axis by the driving force of a motor, wherein a first positioning member effects the positioning of the optical system in the direction of the optical axis independently of the driving force of the motor, a second positioning member effects the positioning of the optical system in a direction perpendicular to the optical axis of the optical system, and a switching member actuates the motor by giving an external force to the optical system, whereby the functional features as well as maneuverability of the optical system shifting device are improved.
