摘要： In a focal plane camera shutter of the type having opening blades and closing blades which are actuated sequentially to provide an exposure, the opening blades are operated by an operating member which is biased in a direction to move the blades to aperture-closing position. The opening blades are moved to open position when the shutter is released by a driving member which is biased in a direction to open the blades and is releasably connected to the operating member by a connecting member. At approximately the termination of the exposure, the connecting member is actuated to release the blade operating member from the driving member whereupon they are moved by the aforementioned bias to closed position. The camera is then reset by moving the driving member to its set position whereupon the connecting member again connects the driving member with the blade operating member. The closing blades may likewise have an operating member releasably connected to a driving member by a connecting member which is released upon termination of the exposure so that the closing blades likewise return to set position.
摘要翻译：在具有依次致动以提供曝光的开启叶片和闭合叶片的类型的焦平面相机快门中，打开叶片由沿着将叶片移动到开闭位置的方向被偏压的操作构件操作。当活门被驱动构件释放时，打开的叶片被移动到打开位置，该驱动构件沿着打开叶片的方向被偏压并且通过连接构件可释放地连接到操作构件。大致在曝光结束时，致动连接构件以将驱动构件从驱动构件释放，由此将它们通过上述偏压移动到关闭位置。然后通过将驱动构件移动到其设定位置来复位摄像机，因此连接构件再次将驱动构件与叶片操作构件连接。闭合叶片同样可以具有通过连接构件可释放地连接到驱动构件的操作构件，其在曝光结束时被释放，使得关闭叶片同样返回到设定位置。

摘要： A camera shutter mechanism including a shutter opening member mounted for pivoting about a first axis between a closed position corresponding to a closed shutter and an open position corresponding to an open shutter, and a shutter closing member mounted for pivoting about a second axis between an open position corresponding to an open shutter and a closed position corresponding to a closed shutter. A movable driving member includes a coupling mechanism for releasably coupling the driving member to the shutter opening member to permit moving the shutter opening member by moving the driving member, and for releasing the shutter opening member from the driving member when the shutter opening member is moved from the open to the closed position. A first spring biases the driving member to move the shutter opening member from the closed to the opened position to initiate exposure, and a second spring biases the shutter closing member to move from the opened to the closed position to terminate exposure. A drive transmission lever mounted on the driving member is positioned for responding to movement of the shutter closing member to the closed position for returning the shutter opening member to the closed position.

摘要： A diaphragm control device for flash photography is incorporated in a programming electric eye camera including an exposure control circuit and capable of automatically setting exposure time and diaphragm aperture according to the light of subject, the exposure control circuit has a photoconductive element and is adapted for controlling an electromagnet.The device includes a diaphragm lever operating in a fixed manner by the action of a spring to define diaphragm aperture, a control arm of a distance setting member, a diaphragm regulation lever controlled by the control arm and a change lever for interchanging first or second positions, at respective positions the diaphragm regulation lever being out of or in the turnable area of the diaphragm control lever.For daylight photography, the diaphragm regulation lever is forced by the change lever to be at the first position, and the diaphragm operating lever is controlled by an exposure control circuit to form a programming shutter adapted for automatically setting exposure time and diaphragm aperture according to the light of subject. On the other hand for flash photography, the diaphragm regulation lever is forced by the change lever to be in the second position, and the diaphragm operating lever is controlled alternatively either by said diaphragm regulation lever or by the exposure control circuit dependent on the light of subject so as to accomplish an exposure through the smaller of respective diaphragm apertures dependent on camera-subject distance and on scene light.

摘要： In a single lens reflex camera, the shutter base plate is provided with a recess in which the reflecting mirror is mounted. This permits the mirror to be closer to the film plane and hence permits the imaging plane, prism and viewing lens of the view finder to be closer to the optical axis of the camera lens, thus reducing the overall size of the camera.

摘要： The operating mechanism for a camera shutter comprises a pivoted actuating member for opening the shutter and a pivoted actuating member for closing the shutter. A driving spring for biasing each of the actuating members in actuating direction has one end acting on the respective actuating member and the other end supported by a ratchet wheel which is coaxial with respective actuating member so that the spring bias can be varied by rotary movement of the ratchet wheel. Spring finger portions of a spring plate which overlies the shutter operating mechanism engage the ratchet wheels to retain them in selected angular positions against the reaction forces of the respective springs. Portions of the spring plate support the spring fingers intermediate their attachment to the spring plate and their free ends engaging the respective ratchet wheels.

摘要： A camera shutter having an aperture, shutter opening blades which travel from a position covering the aperture to a rest position uncovering the aperture to initiate exposure, and shutter closing blades which travel from a position away from the aperture to a position covering the aperture to terminate exposure, and a shutter blade stabilizing device. The stabilizing device includes an elastic member for frictionally pressing at a leading portion of the shutter opening blades at which the driving force is applied to the blades, when the blades are at the rest position, and a member for pressing against the shutter opening blades at a trailing portion of the blades at a portion where the driving force is applied, when the shutter opening blades are at the rest position. The elastic member and the member for pressing together prevent movement of the shutter opening blades when they are at the rest position.
