发明名称 Camera having lens protection cover
摘要 A lens protection cover is contained within a barrel ahead of the objective lens, and opening and closing of this lens protection cover is performed by an actuator operable along the periphery of the lens barrel, whereby it is possible not only to protect the objective lens when not in use, but also to permit camera operation to be controlled by the open and closed positions of the lens projection cover so that faulty operation is prevented.
