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.
