发明名称 Arrangement for photographic data marking
摘要 An arrangement for photographic data marking upon a film strip passing through a photographic camera, especially a high-speed theodolite camera, while utilizing a perforated mask and luminescent diodes carried by a substrate. In accordance with the invention, the arrangement is structured as an integrated component which contains at least the substrate, the semiconductor bodies of the luminescent diodes, the perforated mask and a transparent cover plate. The perforated mask is fixedly connected at the side confronting the film strip with the inner side or face of the cover plate. The semiconductor bodies which are electrically connected by electrical connections with one another and with the substrate are arranged at a slight spacing from the other side or face of the perforated mask.
