An advertising display unit

摘要

An advertising display unit has an outer housing having a display window in a wall of the housing. A tubular poster holding cylinder is rotatably mounted within the housing and carries three posters held against an outer face of the cylinder. A drive motor is operable to rotate the cylinder within the housing to present each poster in turn at the display window for a preset time period for advertising purposes. A lamp mounted within the cylinder back-lights the poster. <IMAGE>
