摘要：A camera with a data imprinting device has a plurality of in-line LEDs producing light focused by an optical system upon a photographic film at a first and a second position, corresponding to a full size format and a panorama size format, respectively. The focused light imprints data images upon the film at the first position are larger than data images imprinted at the second position. The optical system has first and second prisms, with integrated lenses, for reflecting and focusing the light upon the film at the first and second positions, respectively. A shutter plate is selectively positioned over apertures through which the light is focused, thus blocking the light and allowing only a selected imprint to be made upon the film. A vertical pattern of the data image is created by a controller selectively illuminating the in-line LEDs while a horizontal pattern is produced by the controller illuminating the LEDs in coordination with the movement of the film past the apertures. The controller actuates a motor for advancing the film and has a sensor for detecting film travel. A first embodiment has the first prism positioned further from the film than the second prism, which is positioned further from the LEDs than the first prism, such that reflected light from the first prism has a path intersecting that of incident light of the second prism. A second embodiment has the prisms offset from each other in the plane of the film such that light paths do not intersect. The first embodiment has a narrower width than the second embodiment while the second embodiment has a shallower depth than the first embodiment.
