Abstract
A scroll apparatus formed as a box-like framework with a front view area which houses a pair of rollers upon which a message web is wound in a scroll manner such that an exposed portion of the web extends between the rollers along the view area. A drive strap has each of its opposite ends fixed to a respective roller with its respective end portions each wrapped about itself in a circumferential direction opposite the direction that the message web is wound about the associated roller. The drive strap and web thus form a loop drive assembly for the rollers. Tensioning structure is provided for the drive assembly to keep the web taut and to remove slack due to variations in winding diameters. A color panel is positioned adjacent the message web on a side thereof opposite the view area, and the apparatus is internally lit so that the message web is illuminated by light passing through the color panel. Several apparatus, in modular form, may be used to construct a larger display sign.
