  • Camera with lens barrier apparatus
    Patent number: 5842057
    Abstract: A camera has a lens barrier apparatus in which the lens barrier apparatus is driven by a motor that is also used to drive another mechanical element in the camera. The motor is switched between the lens barrier apparatus and the mechanical element by the movement of a lens barrel. The driving of the lens barrier apparatus and the mechanical element are controlled in accordance with the output of a single sensor, for example an encoder. The driving of the lens barrier apparatus is controlled such that the barrier will not close unless the lens barrel is at the housed position and such that if the lens barrier does not open, the lens barrel will not move. The driving is further controlled such that if the lens barrier apparatus does not move to its intended state, the drive is reversed prior to again attempting to drive to the intended state.
