ABSTRACT:
A logic control linear drive magnetic motor is used to reciprocate approximately 180.degree. the flat panels which make a display board. Each panel of the display board is connected to a pulley which is in a plane perpendicular to the longitudinal dimension of the vane. A continuous drive cord is connected to each end of a shuttle cylinder of the motor and is wrapped around the pulley drum. Movement of the shuttle cylinder moves the drive cord which controls the rotation of the vanes.
