Abstract
A mechanism for animating a doll's jaw, eyes and eyelids. A single motor powers all three movements. The eyes and jaw are connected to the motor such that they continually move while the motor is in operation, while the eylids are connected to the motor such that reversal of the direction of rotation of the motor causes the eyelids to blink once. All movements are therefore controlled by controlling the speed and direction of rotation of the motor. Thus, movement of the jaw can be synchronized with a sound track, the eyes move in an apparently random path, and the eyelids blink at random intervals independent of the other facial features' position or movements.
