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 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： A camera shutter equipped with a selftimer device has an interlocking member for coordinating the movement of the camera operating member and the selftimer device to obtain accurate operation of the shutter release member. The interlocking member has a first arm which engages with the operating member during movement thereof at the beginning portion of the shutter release motion and the operating member thereafter drives the interlocking member to a position in which the interlocking member actuates the selftimer device to initiate a timing operation. Near the end of the timing operation, the selftimer device engages with a second arm of the interlocking member and thereafter drives the interlocking member to another position during the course of which a translating lever mounted on the interlocking member actuates the shutter release member to initiate release of the shutter.

摘要： An automatic focusing device for an automatic focusing camera of the double image coincidence focusing type. A coupling mechanism causes an focus detecting movable mirror perform scanning motion according as the stroke of shutter releasing operation. Interlocking with the push-down of the shutter release button, focus detecting motion is performed while the distance from the focal plane to the photographing objective is indicated and/or memorized.During the first half of shutter releasing operation, focus detection and indication and/or memorization of the distance from the focal plane to the photographing objective are performed by the scanning motion of the movable mirror, and during the latter half of the shutter releasing operation, the indication and/or the lense focusing mechanism are controlled by a signal motion corresponding to the memorized value.The memorized value is scanned interlocked with the movement of a timing member released by shutter releasing operation or a focusing member and a lense displacement regulating mechanism is controlled by a signal motion corresponding to the memorized value.

摘要： A focal plane shutter for a camera of the type wherein an image is viewed through the photographing lens by use of a viewfinder arranged on top of the camera body. The shutter blade mechanism comprises a group of opening blades and a group of closing blades, each group of blades consisting of a plurality of separate blades which are actuated to run in the vertical direction of the camera for exposing the film. The lower group of blades has a larger vertical dimension when in the retracted condition than the upper group of blades and such is achieved by using a different number or different size of blades in the two blade groups. In both groups, the slit-forming blades are mounted by means of a link mechanism to effect parallel running movement of the blades. The pivot shafts for mounting the slit-forming blades are disposed at a position outside of the region lying vertically below the viewfinder.
