Abstract
A photographic camera having a photographic lens system freely settable to various focal lengths, an openable and closable lens cover disposed in front of the photographic lens system, an opening and closing mechanism for the lens cover, a motor for providing kinetic energy for the focal length changeover operations of the photographic lens system and also for the opening and closing operations of the lens cover, and a drivable cylinder capable of transmitting the kinetic energy from the motor to the photographic lens system and to the opening and closing mechanism in the form of a mechanical displacement. The opening and closing mechanism opens the lens cover by utilizing a mechanical displacement from a home position to an intermediate position of the drivable cylinder and closes the same by utilizing a mechanical displacement from the intermediate position to the home position of the drivable cylinder, and further changes over a focal position by utilizing mechanical displacements reversibly between the intermediate position and an end position of the drivable cylinder.
