Abstract
A thin blade open-close device includes a base member including spaces accommodating lens units, a cover plate covering the base member partially, and a blade member between the base member and the cover plate. The cover plate has openings aligned with optical axes of the lens units. The blade member includes a first light shield that covers the opening in the cover plate, a light entry opening that connects with the opening in the cover plate, and a second light shield that covers the opening in the cover plate. The blade open-close device includes a drive actuator that moves the blade member in a closing direction to change from an open state to a closed state in which the first light shield and the second light shield in the blade member cover the openings in the cover plate.
