Abstract
A side printing head assembly for printing marks such as characters, symbols, or the like on a moving photographic film includes a light source comprising a plurality of LED units each of which has a plurality of LED elements emitting a plurality of different monochromatic lights. Light guide members are provided, as many as the plurality of LED units, for directing light from the plurality of LED units toward the moving photographic film. There is a driving circuit for driving the plurality of LED units independently from one another so as to form and thereby to print the mark on the moving photographic film.
