Abstract
The camera shutter device incorporated with lens shifting mechanism comprises a driving motor which is so controlled as to be rotated in the normal direction in the focusing process, and in the reverse and normal directions in the exposure process, a cam ring allowing a lens barrel to be shifted from a standard position to at least one forward-shifted position by the rotation of the driving motor in the normal direction in the focusing process, and a shutter blades opening and closing lever allowing the shutter blades to be opened and closed by the rotations of the driving motor in the reverse and normal directions in the exposure process. The camera shutter device permits simplifying the overall structure thereof and the operating sequence from the focusing operation to the exposure operation, and reducing the force and turning stroke required for shutter setting.
