摘要： The disclosed apparatus includes a finder optical system with a liquid crystal display having a plurality of strips of transparent conductive material arranged to display a frame for photography and a light metering area in the field of view of the finder. The liquid crystal display is energized in selected or all areas depending upon which position the objective lens takes when focusing and when zooming, or upon the set value of focal length in an objective lens of zoom type, and upon the in-focus signal of an auto-focus camera. The parallax between the photographic framing of viewfield and the rangefinder view is corrected and the rangefinder spot is displayed in a corrected position.

The aperture of the view finder compartment is removably attached to the camera body aperture while the camera body dark compartment is capable of fixing the view finder dark compartment to one of its side walls. For photographing, the view finder dark compartment is fixed to the aperture of the camera body compartment. When no photographing is required, the view finder dark compartment can be fixed to the side wall of the camera body compartment to make the camera more easily portable.

摘要： A focusing system in a camera having an automatic focus detector to detect a focusing condition of a photo-taking optical system, an electromagnetic driving motor which is actuated in one direction, being controlled by the detector and having its operation stopped when an in focus state is detected by the detector, a movable member which can restrict the operation of said driving motor and at the same time is shiftable in response to the shifting of the photo-taking optical system, and an indicator which indicates the in focus position and is driven by said driving motor. The photo-taking optical system is shifted from a prescribed position in a predetermined direction for adjusting the focus. The movable member is correspondingly shifted from a prescribed position in a predetermined direction to release the restriction over the driving motor and to line up with the position of the indicator manually setting the optical system to the in focus position indicated by the indicator.
