This image could be re-created using vector graphics as an SVG file. This has several advantages; see Commons:Media for cleanup for more information. If an SVG form of this image is available, please upload it and afterwards replace this template with
{{vector version available|new image name}}.
It is recommended to name the SVG file “Etchasketch.svg”—then the template Vector version available (or Vva) does not need the new image name parameter. |
 | This image was uploaded in the JPEG format even though it consists of non-photographic data. This information could be stored more efficiently or accurately in the PNG or SVG format. If possible, please upload a PNG or SVG version of this image without compression artifacts, derived from a non-JPEG source (or with existing artifacts removed). After doing so, please tag the JPEG version with {{Superseded|NewImage.ext}} and remove this tag. This tag should not be applied to photographs or scans.

Summary
| Description |
English: Basic mechanism of operating a 2-dimensional plotter. All of the numbered components correspond to those which move the plotter's stylus horizontally, and the lettered components with those which move it vertically. Device consists of a series of 10 pulleys, 6 cables, 2 rails, and a stylus. Pulley 1 (single-groove) is connected to pulley 2 (triple-groove) via a short infinite reciprocating cable. Two connects to 3 (double-groove) via a longer reciprocating cable which is attached along its upper course to one end of the vertical rail (6), and then a third cable runs from 2 to 3, 4 and 5 (4 and 5 are single-groove) via another much longer loop of cable which attaches between 4 and 5 to the other end of the vertical rail. Likewise, A connects to B, B connects to C and attaches to the horizontal rail (F), and finally B connects to C, D, and E, attaching to F at its other end between D and E. Turning pulley 1 counterclockwise as shown causes 2 to rotate the same way, and this causes all pulleys connected to 2 (3, 4, and 5) to do the same. The rail to which these cables is connected (6, connection points marked in red) will move to the left both at ends, causing the stylus to move in the same direction along the other rail (F). Clockwise movement of pulley 1 has the opposite effect. Pulleys A-E operate the same as 1-5, and act on the horizontal rail (F) to slide the stylus up and down along the vertical one (6). |
