ABSTRACT:
A side printing apparatus for providing latent images of information marks, such as manufacturer's name, date information, film size, frame numbers and the like at the longitudinal sides adjacent each picture frame of a photosensitive product, is adapted to scan the surface of the photosensitive product moving with continuous motion with a deflecting device which deflects a beam of laser light in a direction perpendicular to the direction of the continuous motion of the photosensitive product. Before the deflection, the beam of laser light is modulated according to the pattern of marks by which the latent image is required to be provided on the photosensitive material.
