Abstract:
A photographic camera is provided with a three-legged member which rotates rapidly upon release to synchronize several or all of the following operations: A. INITIATION OF AUTOMATIC EXPOSURE CONTROL FUNCTIONING; B. ACTUATION OF THE CAMERA SHUTTER; C. DISPLACEMENT OF THE VIEWER MIRROR (SINGLE LENS REFLEX CAMERAS) FROM THE CAMERA''S OPTICAL PATH; AND D. ACTUATION OF A PERCUSSIVELY IGNITABLE FLASHLAMP. The three-legged member is energized prior to picture-taking and release is accomplished when the camera user depresses or otherwise actuates the camera release member.
Abstract:
An operating mechanism for a single-lens reflex camera has a slidable control member to which are coupled a shutter setting mechanism, a mirror-actuating mechanism, and a shutter blade retaining lever. Displacement of the control member from an initial position synchronously effects the closing of the shutter and the movement of the mirror to a viewing position prior to exposure, the operation of the shutter to make an exposure, and the activation of the previously deactive retaining lever to prevent rebounding of the shutter blades. The control member is then returnable to its initial position whereby it resets the operating mechanism.
Abstract:
A shutter mechanism comprises an aperture closing blade eccentrically mounted on and movable with an aperture opening blade. The closing blade remains in its open position due to its own inertia until the opening blade has cleared the exposure aperture.
Abstract:
A camera includes a pair of interchangeable lenses, each lens being selectively movable between a stored position out of alignment with the camera''s optical axis and a taking position in alignment with the optical axis. At least one of the lenses is focusable, and a movable actuating member is operatively connected to the lenses for moving one lens to its taking position while moving the other lens to its stored position. The actuating member is connected to the focusable lens by gearing so that, when the lens is moved to its taking position, its focus setting can be adjusted by slight movement of the actuating member.
Abstract:
A camera having a lens cover which, when open, is movable to a lock position blocking the camera''s shutter release button. The cover is normally held out of its lock position by a spring, but is positioned adjacent the camera''s taking lens so that a finger, inadvertently placed over the lens, will also move the cover to its lock position. A visible indicator may be associated with the lens cover so as to move into the camera''s viewfinder if the operator''s finger passes in the field of view of a camera''s taking lens.
Abstract:
Shutter mechanism for a photographic camera in which a shutter blade is opened by a spring loaded impact driver controlled by a shutter release lever. When the blade is driven open it strikes a resilient stop which absorbs the impact energy of the shutter blade and returns the shutter blade softly for engagement by a latch device. The impact energy imparted by the blade to the resilient stop can be employed for various functions, such as the actuation of a switch in an electronic timing circuit that controls shutter speed.
Abstract:
A camera having a flashcube socket and a separate flash device socket adjacent each other. The two sockets are closely located so that, owing to the large lateral dimensions of the flashcube relative to the size of its socket, normal use of either socket prevents normal use of the other socket.
