    摘要： A self developing type photographic apparatus wherein one of the spread rollers is driven by one or two toothed racks forming part of or constituting a manually reciprocable handle. One of the racks further rotates a gear which programs the movements of an expelling device for exposed film units, the movements of a device which controls the width of the gap between the spread rollers and the cocking of the shutter.

    摘要： A prism positioned behind the objective rotates at a predetermined frequency. The pulsed light beam produced thereby is split into a first and second pulsed beam, each falling on a photoelectric transducer element. The first photoelectric transducer element is positioned at a distance from the objective which is less than the distance between the film plane and the objective plane by a predetermined distance. The second photoelectric transducer is positioned away from the objective by a distance exceeding the distance between the film plane and the objective plane by the same predetermined distance. The first and second electrical signals produced by the first and second photoelectric transducer are differentiated and stored. The so-stored signals are compared and a control signal for driving a motor in a first or second direction is furnished corresponding to the difference therebetween. The motor drives the objective either closer to or away from the film plane in response to the control signal.

    摘要： Apparatus for convoluting exposed and copied photographic films on the cores of takeup reels has an advancing mechanism which transports successive films along a given path so that the leaders of successive films can be engaged by the gripper of a pivotable arm serving to transfer the leader of the film in the path toward the peripheral surface of the core of an empty takeup reel. The reel has no flanges or is provided with a single flange carrying or adjacent a fixedly mounted or movable protuberance which defines with the peripheral surface of the core a gap for the leader of the film. Once the leader has entered the gap and the takeup reel is set in rotary motion, the film is wound onto the protuberance and is thus affixed to the core. The length of the protuberance is less than the axial length of the core but exceeds one-fourth of such axial length.

    摘要： A photographic copying machine wherein the images of successive frames on a long roll of spliced-together exposed and developed customer films are copied while successive films are advanced stepwise from a supply reel on a first driven mandrel toward and is convoluted on a takeup reel on a second driven mandrel. The copying machine employs a third mandrel which can support a fresh roll in the plane of the roll on the first mandrel, and a fourth mandrel which can support an empty takeup reel in the plane of the rotating takeup reel. The leader of the fresh roll is located adjacent the film path ahead of the copying station and is automatically advanced into the range of an automatic attaching mechanism when the trailing end of the expiring roll has advanced beyond the copying station. The attaching mechanism secures the leader of the fresh roll to the core of the empty takeup reel, and the machine is then ready to make copies of frames forming part of the fresh roll. The filled takeup reel on the second mandrel is replaced with an empty takeup reel and a fresh roll is placed onto the first mandrel while the machine copies the frames of the roll which is supported by the third mandrel and is convoluted on the takeup reel on the fourth mandrel.

    摘要： An infrared measuring beam is emitted from the camera towards the subject, and reflected back as a tiny light spot projected, by an optics which transversely shifts in dependence upon exposure-objective subject-distance setting, onto one, the other or both of two infrared photodiodes. The signals from the two photodiodes are transmitted in processed form to two output flip-flops through the intermediary of a single, shared signal-processing stage, employing time-division-multiplexed transmission of the two photodiode signals, to assure that the signal processing of the two photodiode output signals be as identical as possible.

    摘要： When the user presses the trigger button, a rod is pulled longitudinally by a drive spring in a first direction from a first to a second position triggering the shutter in the process and a coupling thereafter couples the rod to a transport motor which returns the rod in the opposite second direction back to first position, the rod resetting the shutter in the process, the rod when returned to second position becoming decoupled from the motor so that the latter will not oppose the force of the drive spring for the next first-direction movement of the rod. The crank rod is blocked against first-direction movement by two blocking levers, the first initially being in blocking position and the second initially in unblocking position. When the user presses the trigger button, the first blocking lever unblocks the rod and the latter performs its first-direction movement, the first lever remaining in unblocking position until the user releases the trigger button, and near the end of the second-direction movement of the rod the second blocking lever snaps into blocking position, to prevent an unintentional second exposure, the second blocking lever blocking the rod until the first lever, upon release of the trigger button, can return to blocking position, whereupon the second lever once more assumes unblocking position. When instead of single exposures exposure sequences are to be made, the user sets a manual switch which arrests the second lever in unblocking position, so that the rod performs its first- and second-direction movements alternately for as long as the user keeps the trigger button depressed.
