 It is an example of a four-bar kinematic chain. It consists of four links joined in such a way to form a parallelogram ABCD in which AB=CD and AD=BC. In the figure, OAE always remains in a straight line. Pantograph consists of four turning pair. A and E will trace a similar path but of different scale.
