ABSTRACT:
A motorized character rotation device is provided which comprises a base, a synchronous motor, a rotation member and a character portion. The character portion is secured to the rotation member, which is reversibly rotatable by the motor through an angle of at least 90 degrees to expose a first surface of the character portion at one limit of the angle and to hide the first surface from view at a second limit of the angle. The character portion is secured in position when the synchronous motor is de-energized. A plurality of the character portions comprise one or more complete characters to define a displayed message. An electrical circuit and a method are provided to remotely select and actuate any character portion of the character display system.
