Abstract

A template to form the characters to be written is placed between the light source and the record carrier. The template is formed as a light-switching mask the switching elements of which can be controlled by a character generator. The switching elements may be arranged separately beside each other or in matrix form in accordance with the fact whether the characters are to be written per line or per page. Printing in color is also possible. The optical printer combines the functions of a printer, a picture memory and a display.
