An electro-mechanical display system is disclosed having four viewing stations. The system includes a rotating mirror and alphanumeric character generators, and is capable of simultaneously displaying different information to each of the viewing stations. The information displayed at each station is not observable at the other stations. Only one single-digit character-generator is required to display a line of information to two viewing stations.
