Abstract: A controller for a display sign that displays a series of posters aligned in a row, including a top roller and a bottom roller, controlled by top and bottom motors, respectively. The sign displays one a series of posters arranged on a roll. The posters not in display remain wrapped around the top and bottom rollers as appropriate. The controller allows the poster's positions to be set relative to the rotation of the motors or rollers. When the motor operates to move the rollers to position another poster, the motor can decelerate gradually when approaching the other poster's position. The controller can also be used to program the order of display of the posters and the duration of time each poster is displayed.

Abstract: A modular, graphic display and storage member provides for the attachment of photographs in a curved fashion for ease of viewing, attachment and removal. A number of fins are snap fitted to a central core member so that they may be easily removed by swinging the fin in an arc. Photographs are held in place between the outer end of pairs of fins with reversely positioned claws located at the end of each fin. The module, as assembled, may be used singularly or may be mounted in tandem on a spindle and allowed to rotate for ease of viewing and for decorative purposes.
