It's a mechanical device for changing the size of a drawing or so by moving one pointer on a source image and another with a pencil on a target paper. Obviously, especially if the linkages are a bit worn down, it's rather cumbersome to point to a specific point in the target by moving just the source pointer. But this is the operation of the mouse. http://en.wikipedia.org/wiki/Image:Pantograph.jpg -- Tuomo
