Abstract
The invention contemplates a device for directly recording upon photographic film, such as 35-mm film, data such as time and/or other identification within the exposure frame to which the data is applied. In the described embodiment, the data form is digital, luminously provided by a plurality of LED devices, and a fiber optics bundle transmits each LED-generated digit display direct to the plane in which a pressure plate engages the back surface (i.e., opposite the emulsion surface) of the film. The pressure plate is resiliently suspended, for gently loaded contact with film at the exposure-frame region, and all LED components and their associated fiber-optics bundles are fixedly mounted to, and therefore resiliently suspended with, the pressure plate.
Claims14
In a photographic camera wherein film to be exposed is held by a pressure plate against a fixed open frame in the focal plane of an exposure to be made, the pressure plate being resiliently mounted with respect to said frame such that contacting adjacent surfaces of the film and pressure plate are in substantially a common plane, and wherein luminous data pertaining to a given film exposure from a luminous-data source are to be embodied in the film within the frame of the exposure, the improvement in which the pressure plate has at least one aperture in register within a portion of the exposure frame and wherein means including a fiber-optics bundle comprising a dense array of parallel fibers is fixedly carried by said pressure plate and extends through the aperture and to said film-contacting plane, whereby one end of said fiber-optics bundle terminates at said plane, the other end of said fiber-optics bundle terminating in a plane adjacent said luminous data, there being no optical element between the luminous-data source and the adjacent other end of said fiber-optics bundle.
In a photographic camera wherein film to be exposed is held by a pressure plate against a fixed open frame in the focal plane of an exposure to be made, the pressure plate being resiliently mounted with respect to said frame such that contacting adjacent surfaces of the film and pressure plate are in substantially a common plane, and wherein an array of luminous data characters pertaining to a given film exposure from luminous-data display means is to be embodied in the film within the frame of the exposure, the improvement in which the pressure plate has at least one aperture in register within a portion of the exposure frame and wherein said luminous-data display means includes an imaging fiber-optics bundle comprising a dense array of parallel fibers of combined section spanning said array and confronting said array at first corresponding ends of said fibers, said fibers being fixedly carried by said pressure plate within the aperture and operative at their opposite ends to present a display of luminous data at said film-contacting plane, there being no optical element between said luminous-data array and the confronting end of said fiber-optics bundle.
