Abstract
Abstract Data such as the place and time a picture is taken are written on a tape in a data capsule which is detachably mounted in the camera body. A light source and an optical system are mounted in a hollow tube which is movable along the tape to scan the data and project the data onto an edge portion of the film when the camera shutter is opened. The tube has an aperture facing the film surface and another aperture facing the tape through which the image of the data passes. The aperture facing the tape is arranged very close to the surface of the tape so that light from the light source is prevented from being scattered into the body of the camera and adversely affecting the film.

Claims Analysis
Total Claims: 15
Claim 1
Independent Claim
354 words
A data recording system for use with a camera having a camera lens and a shutter mechanism operating a shutter comprising, in combination: data means detachably mounted in the camera on which data to be recorded is printed; illumination means to illuminate the data on the data means; optical means to project an image of the data onto a film surface, said optical means comprising a lens to focus the data onto the film surface and a reflector to reflect the image of the data so that the image is incident on the film surface at substantially a right angle; enclosure means operatively arranged within the camera to be moved along the data to scan the data, the illumination and optical means being mounted within the enclosure means, the enclosure means comprising means defining a first aperture facing the film surface through which the image is projected onto the film surface by the optical means, means defining a second aperture closely adjacent to the data on the data means through which the data is illuminated by the illumination means and is visible to the optical means, and baffle means to prevent light from the illumination means from directly entering the optical means; drive means actuated by the camera shutter mechanism to energize the illumination means and move the enclosure means when the camera shutter is opened, the drive means comprising a sliding link operatively connected to the camera shutter mechanism, a changeover link to select whether or not to record the data on the film, a shutter plate operatively connected to the sliding link to cover a portion of the film surface on which the data is recorded when the camera shutter is opened, and an electrical circuit comprising a power source to energize the illumination means and a motor for moving the enclosure means, a first normally open switch which is closed by the changeover link when the date is recorded on the film and a second normally open switch which is closed by the sliding link; and rail or track means by which the enclosure means is slidably mounted within the camera.
