摘要： A monocular reflex camera having a viewfinder mirror and carrier assembly movable between a viewing position of the camera and an exposure taking position comprises a pivoted crank arm of which the pivot shaft is articulated connected with the mirror carrier close to the centre of gravity. The carrier has a lateral stop lug arrange at a distance from the pivot shaft and protruding into the path of the movement of the crank arm. A spring urges the stop lug into abutment with the crank arm. Stops are provided for locating said mirror assembly in the exposure taking position, and also in the viewfinding position. During the viewing position of the mirror and over a substantial portion of its travel into the exposure taking position, the lug is maintained in engagement with said crank arm by said spring and on arrival at the picture taking position the lug disengages the crank arm against the action of the spring.

摘要： The photographic bellows unit is provided with a device for indicating the distance between the standards which support the bellows and are adjustable relative to each other. There are arranged between the standards (2;3) two scissors-shaped levers (8;13) which are hingedly inter-connected at one lever end and whose other end is rotatably hinged to respectively one of the standards (2;3). An index (15) is arranged on one pivotable lever (13) and a measuring scale is arranged on the other pivotable lever (8).In this manner it is possible to avoid the computational determination of the respective distance between the two standards as the indicating device allows the distance between the two standards to be read directly irrespective of the position of the standards with respect to the guide.
摘要翻译：照相波纹管单元设置有用于指示支撑波纹管并且可相对于彼此调节的标准之间的距离的装置。在标准（2; 3）之间布置有两个剪刀形杠杆（8; 13），其在一个杆端铰接地相互连接，并且另一端可旋转地铰接到标准（2; 3）中的一个。索引（15）布置在一个可枢转的杠杆（13）上，并且测量标尺布置在另一个可枢转杠杆（8）上。以这种方式，可以避免两个标准之间的相应距离的计算确定，因为指示装置允许直接读取两个标准之间的距离，而与标准相对于引导件的位置无关。

摘要： The blade-type focal plane shutter formed with a plurality of telescopically operating opening blades movable in front of a film gate. A drive lever for the opening blades is operatively connected to said opening blades and carries a diffusedly reflecting mirror which before the commencement of the exposure operation lies in front of the opening blades in the film gate and is movable out of the film gate during the opening movement of the opening blades. The mirror together with the opening blades forms a reflection factor which corresponds to the mean reflection factor of different film types.

摘要： An arrangement for the automatic critical focusing of optical systems in mirror reflex cameras provided with a partially transmitting reflex mirror, an image field lens arranged in the viewfinder ray path as well as a range-finder image plane, which is equivalent to the film plane. The range-finder image plane, which contains image-forming and deflecting optical components, is arranged in the optical axis of the viewfinder system. By these means a reduction of the expenditure of optical components as well as of the required assembly and adjustment expenditure for automatic critical focusing devices is achieved.

摘要： A release mechanism is provided for the viewfinder mirror, which is held in the viewfinder position, of a single-lens mirror reflex camera having a photoelectrically controlled lens diaphragm. A locking device in the release mechanism, which device interrupts the closing of the lens diaphragm, comprises a detent tooth (31) which keeps the viewfinder mirror (27) in the viewfinder position against the action of the swivel spring (30). The tooth (31) can be brought out of engagement with the swivelling lever (10) of the viewfinder mirror (27) upon the electromagnetic release of the locking device for the interruption of the closing of the lens diaphragm.This achieves a release of the viewfinder mirror, and thus the initiation of the exposure operation, to be effected approximately simultaneously with the photoelectrically controlled interruption of the closing of the diaphragm.
摘要翻译：为具有光电控制的透镜光阑的单透镜镜反射相机提供了用于保持在取景器位置的取景器反射镜的释放机构。释放机构中的锁定装置，该装置中断透镜隔膜的关闭，包括止动齿（31），其抵抗旋转弹簧（30）的作用将取景器反射镜（27）保持在取景器位置。当锁定装置电磁释放以阻止透镜隔膜的关闭时，齿（31）可以与取景器反射镜（27）的旋转杆（10）脱离接合。这实现了取景器反射镜的释放，并且因此开始曝光操作，与光电控制中断隔膜的关闭大致同时进行。

摘要： The exposure metering circuit comprises a differential amplifier, whose inputs are connected to a measuring bridge consisting of a photo-conductive cell and setting controls for the insertion of exposure factors and whose outputs are connected to light-emitting elements for the indication of a set under-exposure, over-exposure or the correct exposure. The two measuring bridge feed points are connected across a resistor, on the one hand, and across a transistor which is driven by means of a voltage derived from the common emitter circuit of the differential amplifier, on the other hand, to an operating voltage source.

摘要： The lamellar focal-plane shutter for monocular mirror reflex cameras comprises a swivelling viewfinder mirror and shutter blades returning automatically to their starting positions after each exposure operation. The intrinsically stationary end of an opening spring which is connected to an opening lever is fastened to a first tensioning plate and the intrinsically stationary end of a closing spring, which is connected to a closing lever, is fastened to a second tensioning plate. Both tensioning plates are interconnected by a coupling rod which is tensioned against the action of a return spring upon the winding and cocking action of the camera. The rod is held in this tensioned position by a detent lever which can be actuated for the release of the coupling rod by means of a releasing arm which is moved back to its start position when the viewfinder mirror returns to the observing position.

摘要： A focal-plane leaf shutter for photographic cameras, comprises an opening group of leaves and a closing group of leaves, each group having a main leaf which forms a parallelogram linkage with a pair of carrier levers, and secondary leaves. The main leaves serve to define an exposure aperture. The carrier levers are mounted by means of stationary pivot journals on a plate at one short side of the exposure aperture and the main leaves are pivotally connected by means of bearing journals to the free ends of the carrier levers. The secondary leaves are connected with the carrier levers at intervals between the pivot journals and the bearing journals. The two innermost carrier levers forming parallelogram linkages with the main leaves are mounted on a common pivot journal.

摘要： A flash switching arrangement for a camera which includes a shutter with an opening leaf and a closing leaf and has a contact nipple and a contact shoe for the attachment of flash units. The switching arrangement includes first and second switching means electrically connected between the first contact shoe and the contact nipple respectively. First coupling means are connectible between the first and second switching means and the opening leaf of the shutter. Second coupling means are connectible between the first and second switching means and the closing leaf of the shutter. On actuation of the shutter, the opening leaf effects closure of both the first and second switching means to ignite the flash unit and after exposure, the closing leaf effects opening of both the first and second switching means.

摘要： A monocular reflex camera having a device for adjusting the viewfinding position of a viewfinder mirror of which the pivot spindle is arranged in crankshaft manner in the camera housing, the viewfinder mirror being urged by a spring in the viewfinding position against first and second stop devices. Each stop device consists of a stop and a flat face arranged opposite to the stop. The flat faces of the two stop devices are arranged either on a setting carrier in the camera housing or on the mirror carrier. The flat faces of the two stop devices extend in mutually parallel planes. The first and second stop devices are shiftable both in relation to one another for the adjustment of the oblique position of the viewfinder mirror and in common for the sharp focussing of the viewfinder image.
