摘要： An electrically operated shutter in which an exposure aperture is opened by actuation of a shutter blade opening member and closed by actuation of a shutter blade closing member and exposure time is controlled in accordance with the duration of excitation of an electromagnet. The shutter is comprised of a disengaging member for causing said shutter blade closing member to actuate upon being attracted to the electromagnet during excitation thereof, and an engaging member for causing the shutter blade opening member to actuate upon being actuated by the movement of a control member if the shutter is released. When the electromagnet is not normally energized, the disengaging member is engaged by a cam portion of the engaging member on the initial operating period of shutter release and disengaged upon lapse of a preselected time from the shutter opening operation.

摘要： A camera shutter has a set of shutter blades movable from an initial closed position in which the blades close an exposure aperture to an open position opening the exposure aperture and then to a final closed position again closing the exposure aperture. Opening and closing driving members sequentially drive the shutter blades from the initial closed position to the open position and then to the final closed position to effect an exposure. A cocking mechanism coacts with the opening and closing driving members for cocking the camera shutter to move the shutter blades from the final closed position to the initial closed position in readiness for taking an exposure. A rebound preventing device is provided for preventing rebound of the shutter blades after reaching their final closed positions and comprises a notched pin on a lever of the cocking mechanism engageable with a hook portion of the closing drive member to thereby prevent rebounding of the shutter blades. During cocking of the camera shutter, the cocking mechanism disengages from the opening and closing driving members which are thereafter free to effect an exposure.
摘要翻译： 相机快门具有一组快门叶片，其可以从初始关闭位置移动，其中叶片将曝光孔关闭到打开曝光孔的打开位置，然后再次关闭曝光孔的最终关闭位置。 打开和关闭驱动构件顺序地将快门叶片从初始关闭位置驱动到打开位置，然后到最终关闭位置以进行曝光。 起动机构与打开和关闭驱动构件共同作用以使照相机快门将快门叶片从最终关闭位置移动到初始关闭位置，以准备曝光。 提供防弹装置，用于防止快门叶片在达到其最终关闭位置之后反弹，并且包括与该闭合驱动构件的钩部接合的起动机构的杆上的切口销，从而防止快门叶片的反弹。 在拍摄相机快门时，起动机构与打开和关闭驱动部件脱离接合，随后可以自由地进行曝光。

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.

摘要： A shutter having two groups of shutter blades. One group of shutter blades opens the shutter and a second group of blades closes the shutter. A shutter-opening actuation member releasably locked by a locking pawl when the shutter is cocked, actuates the shutter-opening group of shutter blades for taking an exposure. A shutter-closing actuation member releasably locked by a second locking pawl actuates the shutter-closing group of shutter blades for completing the taking of an exposure. An electromagnet in an exposure control circuit is energized during the taking of an exposure and deenergized to control the exposure time and terminate the exposure. A control member that controls the release of the control member by its locking pawl is biased by a single spring. The single spring develops a force directed toward applying the control member to the electromagnet when the shutter is cocked and develops a force directed toward separating the control member from the electromagnet and releasing the actuation member and actuating it to close the shutter when the electromagnet is de-energized.

摘要： A camera shutter having a plurality of shutter blades operable from a shutter-closing operative position to a shutter-opening operative position and back to the shutter-closing operative position. An opening driving lever and a closing driving lever are provided for operating the shutter blades to their operative positions. A rebound preventing arrangement is provided by providing pins fixed on the opening and driving levers and making provision on a cocking lever for holding the driving levers from rebounding upon reaching their terminal operating positions in activating the shutter blades in opening and closing the shutter. The pins on the driving levers are engaged at these terminal positions by the locking lever and releasably held to preclude rebounding thereby to preclude rebounding of the shutter blades.

摘要： A camera shutter control mechanism for controlling a shutter opening comprises an opening member movable in an opening direction for opening the shutter opening to start an exposure and a closing member movable in a closing direction for closing the shutter opening to terminate the exposure. Opening and closing pawls releasably lock the opening and closing members in their charged positions. An operating member actuates the opening pawl so as to release the opening member for movement in the opening direction and during the course of such movement, the opening member actuates an interlock lever which in turn actuates an adjustable fulcrum lever for actuating the closing pawl to release the closing member for movement in the closing direction. An exposure period setting member is arranged so as to adjust the operation of the fulcrum lever with respect to the closing pawl and for selectively effecting movement of the fulcrum lever to operative and inoperative positions. A control lever operates the closing pawl in the event the fulcrum lever is adjusted to a position in which it is unable to do so. The control lever is releasably locked in a charged position by an engagement pawl which releases locking engagement with the control lever upon movement of the opening member in the opening direction.
