Origin of pantograph:
pan•tog′ra•phy-ˈtɒg rə fi(n.)
mechanical device used to copy a figure or plan on a different scale
A mechanical linkage based on parallelograms causing two objects to move in parallel; notably as a drawing aid.
A pantograph can be adjusted to make either scaled or exact copies.
A pattern printed on a document to reduce the ease of photocopying.
I was impressed by the quality of the pantograph; I hadn't noticed it on the original, but the copies were covered in unpleasant lines.
A similarly-formed conductive device, now usually Z-shaped, that collects electric current from overhead lines for trains and trams.
Origin: From pantographe, from panto- (from παντός, genitive singular of πᾶν) and -graphe (from γράφειν)
an instrument for copying plans, maps, and other drawings, on the same, or on a reduced or an enlarged, scale
A pantograph is a mechanical linkage connected in a manner based on parallelograms so that the movement of one pen, in tracing an image, produces identical movements in a second pen. If a line drawing is traced by the first point, an identical, enlarged, or miniaturized copy will be drawn by a pen fixed to the other. Because of their effectiveness at translating motion in a controlled fashion, pantographs have come to be used as a type of motion guide for objects large and small. A common example of the use of a pantograph assembly as mechanical guide frame is the extension arm of an adjustable wall-mounted mirror.
