Abstract
Method and apparatus for creating a display including a novel shuttering assembly and drive mechanism therefor. The shuttering assembly alternately presents first and second shutter panels to a window forming an element of the display. The panels are connected to cams on a rotatable axle positioned in spaced relation to the opening and alternately mask the opening on reciprocal rotation of the axle. A drive rod is connected at a first end to a dog on the axle to rotate the axle. The drive mechanism moves the drive rod which has its second end connected to a movable drive member. Preferably a plurality of shutter assemblies are provided, and a reciprocally rotatable drive disc carries solenoids having plungers to selectively engage the drive members. A single cycle motor rotates the drive disc, and logic circuitry permits selected activation of the solenoids. The method includes the step of moving all shutter assemblies into a no display mode at mid-cycle during the reciprocal movement of the drive disc.
