    摘要: A motion picture camera with variable focal length lens wherein the zooming collar and the distance selecting or focusing collar on the lens barrel are rotatable to neutral positions by an actuating member which is movable at right angles to or in parallelism with the optical axis of the lens. In such neutral positions of the collars, the focal length of the lens is satisfactory for the making of exposures in daylight or artificial light, and the distance setting corresponds to a distance of 4 to 6 meters to thus guarantee an acceptable depth of field for exposures of subjects located anywhere between closeup and infinity. The actuating member can further close a master switch to allow for starting of the camera motor in immediate response to depression of the release trigger.

    摘要: A casing, particularly for roll film cartridges, includes a hollow housing having a chamber for closely receiving a film cartridge and a channel which communicates with the chamber. The channel is operative for receiving a length of roll film which extends out of the cartridge when the latter is inserted into the chamber. The channel extends tangentially to the chamber and has at least one flat inner surface along which the length of roll film can extend to be held in flat condition.

    摘要: A sheet of exposed and developed instant-camera film is discharged from an instant camera and then inserted by the user into a film-holding structure on the back of the camera which very accurately positions the film sheet, such that upon removal and reinsertion of the film sheet into the holding structure the film sheet will always assume a predetermined position. The camera is provided with a multihead magnetic head unit mounted for reciprocating motion along a magnetic strip or coating provided at a marginal portion of the inserted film sheet. During first-direction travel of the head unit, one head records, and during second-direction travel of the head unit a different and differently located head records onto a further segment of the magnetic strip. After recording, the recorded information, e.g., spoken words identifying the subject just photographed, can be reproduced, and if desired erased.

    摘要: A novel film cartridge, camera for use with such cartridge and method of making such cartridge are disclosed. The cartridge is in form of a pocket of a material which is impermeable to light and which accommodates a multi-exposure film strip having a length at least equal to the length of the pocket. The pocket is provided with at least one opening extending transversely to its elongation and through which a leading end of the film strip extends to the exterior of the pocket so that it can be engaged by a film transporting mechanism of a camera suitable for accommodating such a pocket, which mechanism transports the film strip either in one continuous movement out of the pocket and into a storage space of the camera from where it is sequentially transported into the pocket in increments during which exposures are made, or else the film is sequentially transported out of the pocket and into the camera storage space with exposures being made during each transporting step and the exposed film is thereupon returned in a single movement into the pocket. However, the pocket may also have two parts one of which accommodates the non-exposed film strip which is then transported during exposures into the other part so that the film strip becomes completely located in the other part when it is fully exposed and a re-transportation into the first part of the pocket is not necessary. Cameras suitable for use with various embodiments of the novel cartridge are also disclosed, as well as methods of making the cartridge.

    摘要: A photographic still or motion-picture camera has a viewfinder and a manually moved focus adjuster, such as a focussing ring. When the user peers into the viewfinder, there is a visible indication of the direction in which the focus adjuster should be manually moved to reduce the state-of-focus error, for example two curved illuminated errors, one pointing clockwise and the other counterclockwise, only one of which lights up to indicate the direction in which the focussing ring should be manually turned. When the state-of-focus error has been reduced to zero or a minimum, this is likewise indicated, for example because neither curved arrow is illuminated. To control the activation of the indicating elements, use can be made of components of a conventional completely automatic focussing system, but minus the adjusting motor of such system and minus superfluous motor-energization control circuitry. In this way, the user is provided a simple and unequivocal guide when manually focussing, without the cost, complexity, bulkiness and power consumption of a complete automatic focussing system including an adjusting motor and motor-energization control circuitry.
