    摘要: A helicoid thread mechanism which comprises a male helically threaded tube and a female helically threaded tube is provided with a helically threaded block for threadedly engaging the female tube onto the male tube. A sliding frictional contact noise which is produced between the two tube members when they engage with each other is eliminated by suitable selection on the helically threaded shape and the material of the block.

    摘要: A sound motion picture camera capable of overlapping exposures by automatically controlling the sequence of a first step beginning with stopping of the take-up spool in a film cassette from further rotation in response to initiation of an overlapping exposure operation and terminating with a predetermined length of film being accumulated in the cassette in the form of a slack loop, a second step of rewinding the length of the looped film without further exposing the film and a third step of transporting the rewound film in the forward direction again while exposing the film again, characterized by the provision of control means for allowing release of a head pad from pressure contact against the magnetic head when the above second step starts.

    摘要: A sound motion picture camera capable of using a sound film is disclosed. The camera includes a film receiving chamber having an image recording location and a sound recording location, a first film feeding device for intermittently transporting a film loaded in the chamber from the image recording location toward the sound recording location, a second film feeding device for transporting the film transported by the first film feeding means further downstream from the sound recording location at a substantially constant speed, a switching device interposed between the first and second film feeding devices and a control device for controlling the operation of the film feeding devices. The switching device is so designed that ON-OFF of the switch is controlled by the movement of the film and that the switch produces pulse signals at an almost constant interval so long as the film transporting operations of the first and second film feeding devices are going well keeping a desired proper operating relation therebetween. But, whenever the operating relation of the two film feeding devices becomes disordered, the switch device continues putting out positive or negative signals. These signals are detected by the control device which terminates the film transporting operations of both the first and second film feeding devices when the ON or OFF signals continue coming out from the switching device for a longer time period than a predetermined time duration.

    摘要: A self-timer for cinecameras wherein an electric delay circuit is used for detecting a length of time from the release to the commencement of a photographing process which takes place with an electric power having been actually supplied to a film feeding motor. The amount of the rotation made by the film feeding motor from the start of the rotation of the motor is either mechanically or electrically detected. When the detected amount of rotation reaches a preset value corresponding to a number of frames of the film required for self-timer photographing, the motor is stopped to terminate the photographing operation, so that the photographing operation with the self-timer can be accomplished exactly for a preset number of frames.

    摘要: A light metering system for a photographic camera which may be selectively operated in a through-the-lens (TTL) light metering mode or an outside-the-lens (OTL) light metering mode to improve the exposure control accuracy over an extended range of light levels particularly towards the low light level side. In one embodiment, the light metering system employs a single light value sensing element in combination with light path changeover means arranged upon movement to change over the light metering aspect between the TTL and OTL light metering modes. In another embodiment, there is provided two light value sensing elements of different light response characteristics from each other for adaptation to the respective light metering modes in combination with a circuit transfer switch operable to select either the TTL light metering mode or the OTL light metering mode. With a camera equipped with a shutter preselection automatic exposure control range and a diaphragm preselection automatic exposure control range, it is possible to realize suitable combinations of the exposure control modes with the light metering modes.
