ABSTRACT OF THE DISCLOSURE: This invention is concerned with a pantograph comprising a support post rotatably mounted in a base, a first arm extending perpendicular to the post and a second arm extending perpendicular to the post and parallel to the first arm. The first arm is mounted onto the post to rotate with it and to translate with respect to it. The second arm is mounted on the post to rotate with, and with respect to it. A follower member is fixed on the first arm and a tracing member is slidably mounted on the second arm. Suitable gear means convert translation of the first arm into translation of the tracing member along the second arm. This improved pantograph is particularly useful in that it allows for modification of the angle existing between the first and second arms and accordingly of the positions where must be placed the drawing to be reproduced and the sheet of paper on which this drawing must be reproduced, without modifying the capacity of reproduction of the pantograph.
