The drawing pen (1) is mounted on an ink capsule (2) housed in a casing (3), and the carrier is notched (3') to move on a graduated scale guide. The capsule is separated from its casing by a spring (6) and it is solid with or jointed to a push button (7) which moves the casing top to allow the user to compress the spring and apply the pen to the drawing. - The push button head (8) can be unscrewed or retraced to renew capsule ink, and the carrier top can be lifted to give access to the capsule and pen for cleaning or replacement.
