1. A visualizer apparatus comprising:

  • a housing;

    means defining a film gate in the housing;

    means for illuminating one side of the film gate;

    a plurality of spools in the housing beyond the film gate;

    a plurality of film strips in the housing and superimposed on each other with the film gate to form a composite illustration when properly aligned, each film strip being connected to a different spool so that when any spool is rotated in the proper direction the film strip connected to it will wind around the spool;

    a rotatable drive element associated with each spool in the housing and normally being disengaged from its spool so that it will rotate independently of its spool;

    an electric motor in the housing;

    means coupling the electric motor with the drive elements for all of the spools so that when the electric motor is energized all the drive elements will rotate;

    clutch means associated with each spool for coupling the spool with its respective drive element when the clutch means is actuated; and

    separate switch means associated with each clutch means for electrically connecting the motor with a source of electrical energy when the clutch means associated with the switch means is actuated, whereby when a specific clutch means is actuated, the electric motor will be energized, causing all the drive elements to rotate, and the spool associated with the actuated clutch means will rotate so that its film strip will wind around it.
