Abstract
In an automatic drafting apparatus having at least one tubular writing pen (1) held in a drawing head (3), and movable between a rest position, in which the lower end of its tubular writing tip (2) is sealed by a laterally movable sealing element (9), and into a raised intermediate position, in which the element (9) is moved laterally out of the way of the writing tip (2), enabling the writing pen (1) then vertically to be lowered into a drawing position. An improved actuation element (11) means is moved laterally back and forth to move both the tubular writing pen (1) and the sealing element (9). This actuation element further comprises a cam or guide contour surface (13, 14, 15, 16) to engage a pin guide operatively connected to the writing pen, thereby to effect vertical movement of the writing pen (1) and also an oblong lateral recess coupled with the sealing element (9) through a second pin (19), for the purpose of defining a selective lateral displacement of the sealing element.
