摘要： A camera shutter mechanism comprises a shutter actuating lever movable between a cocked position and a rest position to actuate a part of the camera shutter mechanism, and a cocking lever having an abutting portion for abutting the actuating lever to move the latter from the rest position thereof into the cocked position thereof. The cocking lever and the actuating lever together include a locking mechanism which releasably locks the actuating lever in the rest position. The locking mechanism and the abutting portion are arranged so that when the actuating lever approaches its rest position, it engages the abutting portion so as to rotate the cocking lever into a position in which the locking mechanism locks the actuating lever.

摘要： A shutter operating mechanism of a camera shutter which has an opening blade and a closing blade operated sequentially to open and close a shutter aperture for an exposure comprises an opening spring normally biasing the opening blade to move from a closed position in which the opening blade covers the shutter aperture to an open position in which the opening blade uncovers the shutter aperture; a second spring normally biasing the closing blade to move from a closed position in which the closing blade covers the shutter aperture to an open position in which the closing blade uncovers the shutter aperture; and a third spring normally biasing the closing blade to move from said open position to said closed position, the arrangement being such that when the shutter is charged, the opening blade and closing blade are in said closed position and when the shutter is released, the closing blade is moved under the bias of said second spring from said closed position to said open position, then the opening blade is moved under the bias of the opening spring from said closed position and to said open position, thereafter the closing blade is returned under the bias of said third spring from said open position to said closed position, thereby completing the exposure. The opening blade may then also be moved to closed position by a fourth spring.Furthermore, there are provided electrical contacts operated by the movement of the closing blade. When the closing blade is moved to uncover the aperture, the contacts are opened or closed and, after the exposure, are closed or opened again by returning movement of the closing blade to the first position.

摘要： A camera shutter includes a pair of spaced apart base plates supporting the various shutter components. At least one of the base plates is formed entirely of synthetic resin material which is electrically insulative and which possesses lubricating properties. The synthetic resin base plate has a set of tubular portions extending toward and connected to the other base plate and also has a set of shafts turnably supporting some of the shutter components, such as the control lever and control cam. The synthetic resin base plate also includes a hollow winding frame about which is wound a coil and in which is slidably inserted an armature to form an electromagnet for use in controlling the shutter operation. The use of a synthetic resin base plate dispenses with the necessity of separate lubrication and enables formation of a smaller shutter.

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： 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： 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.
