The Pantograph is a drawing instrument to magnify
figures. One arm contains a small pointer
while the other holds a drawing implement, and
by moving the pointer over a diagram, a copy of
the diagram is drawn on another piece of paper. By
changing the positions of the arms in the linkage
between the pointer arm and drawing arm, the
scale of the image produced can be changed.
