ABSTRACT:
A mirror image apparatus for use with a pantograph for drawing, engraving, milling, and similar applications wherein tracing and creating a mirror or reverse image is required. The apparatus is characterized by broadly having a stylus which operates between a first plane and a second plane. The first and second planes are parallel to each other with the second plane disposed above the first plane. One end of the stylus is used for drawing an image or tracing an image on the first plane while an opposite end of the stylus is used for engaging and creating on the second plane a mirror image of the drawing or tracing produced on the first plane. When drawing, the stylus may be a pen, pencil or any other drawing instrument wherein the stylus has opposite ends for drawing an image on the first plane while at the same time creating a mirror image on the second plane. When tracing with the stylus and using a template, the template may be mounted face up on a top surface of the first plane or mounted face down on a bottom surface of the second plane. While an image is traced by one end of the stylus in the template, the opposite end of the stylus creates a mirror image on the adjacent and parallel plane. The apparatus can further have a first stylus with one end drawing or tracing on the first plane and a second stylus pointed in an opposite direction from the first stylus. The second stylus engages the second plane for creating a mirror image of the drawing or tracing produced on the first plane.
