  • Patent number: 4705374
    Abstract: A case hinges to the side of the movie camera next to the ground glass. One end of a viewfinder tube mounts pivotally to the case; the other supports an ocular. Light from the inverted image on the ground glass passes, at a right angle to the camera side, into the case. An Amici prism in the case reerects the image and reflects the light rearward to a beam splitter. The splitter passes part of the light rearward to a 45.degree./90.degree. prism and then upward through a lens and iris to a video port and neutral-density filter. The beam splitter deflects the rest of the light outward, at a right angle to the camera side, into the finder tube. There another 45.degree./90.degree. prism (that rotates with the tube) deflects the light rearward in the tube to a lens that reimages the scene at the ocular. The movie camera can thus be tilted while the tube and ocular are at constant height, but prism rotation twists the image about the optical path.

    Abstract: A multipurpose film handling cassette of the type in which a photographic film strip is exposed, processed and projected without removal of the film from the cassette is provided with a one-piece indicating element for signaling to the apparatus with which it is to be used the unprocessed or processed condition of the film within the cassette. A contact element is held, prior to processing, against a spring force into a first position wherein it will be engaged by a pair of contacts in the other apparatus when inserted therein. The element is held in this unprocessed position by a slidable element, which element is displaced responsive to film advancement following processing. Such movement of the slidable element permits the biasing force to displace the contact element to a second position wherein it will not be engaged by the contact of the other apparatus, thus signaling the presence of a processed cassette.

  • Patent number: 4227781
    Abstract: A cinematographic system including a programmable viewing apparatus by which an exposed photographic film strip in a multipurpose cassette may be processed, viewed by projection, and rewound, either entirely or for a selected film length for replay, without removal from the viewing apparatus. A control circuit is provided which continuously measures the position of the film strip in the cassette and precludes projection of the leading end of the film strip in response to signals received from the electronic logic system of the viewing apparatus. The signals condition the circuit to count in either the forward or reverse direction depending upon the direction of film strip movement. The count, which corresponds to the position of the film strip, is continuously displayed by the viewing apparatus. When the count is at or below a predetermined number corresponding to the length of the leading portion, the circuit will prevent the projection lamp from turning on during a project cycle.

  • Patent number: 4198133
    Abstract: A cine camera for taking talking pictures comprises a film-feeding mechanism which includes a driven capstan and a pinch roller normally spaced therefrom to facilitate insertion of a section of film therebetween when the camera casing is loaded with a sound-film cassette. A sensor, upon detecting the presence of such cassette in a receiving chamber of the casing, causes the pinch roller to move closer to the capstan, either via a mechanical linkage or by deactivating a detent normally blocking a displacement of the pinch roller under spring pressure. This displacement under the control of the sensor may establish a standby position, with the pinch roller still separated from the capstan by a clearance wider than the film thickness, that clearance being subsequently reduced by the operation of a trigger, a mode-selector switch or the like to clamp the film between pinch roller and capstan.

  • Patent number: RE30808
    Abstract: A cine camera for taking talking pictures, in which a film is moved intermittently past an image gate by a reciprocating traction claw and continuously past a recording head by a rotating capstan coacting with a pinch roller, includes a latch by which the pinch roller can be held spaced from the capstan in an inactive position. The latching of the pinch roller in this inactive position, against the force of a biasing spring providing the necessary contact pressure during filming, is accomplished upon deactivation of the film drive by the residual kinetic energy of an inertial mass such as a flywheel which is coupled with either the capstan drive or the claw drive. The latch is released upon actuation of a trigger, either directly or through the intermediary of the claw drive. The biasing spring may be part of a toggle mechanism tripped by a presetting member, such as a sensor detecting the presence of a sound-film cassette in the camera.
