ABSTRACT:
A side printing apparatus includes a plurality of light emitting members arranged in a line perpendicular to the forward direction of a film so as to provide several kinds of dot patterns which are exposed on the film as latent images of characters, symbols and so on. A detector for detecting the film position is provided to produce position signals which operate to cause a control to drive selectively the light emitting members to emit light in accordance with the position signals. The light rays from the light emitting members are focussed on the film as light spots.
