Abstract
A drawing pen exchanging device for transferring a drawing pen between a drawing head (4) and a drawing pen magazine (5) in a computer controlled drawing device. The drawing pen (7) is held against a stationary holding area in the drawing head (4) with the aid of a spring holding element (14) and against a stationary receptacle area (11, 12) in the drawing pen magazine (5) by means of a spring-pressure element (24). Through a sliding cooperation with a guide (25) provided to the side of the stationary holding area (21,22), the holding element (14) is swung out to transfer the drawing pen (7) from the drawing head (4) into the drawing pen magazine (5) and the drawing pen (7) then will be held back by the pressure element (24) in the drawing pen magazine (5). When the drawing pen (7) thereafter is to be removed from the drawing pen magazine (5) the holding element (14) is operable not to engage the guide (25) and thereby will pull the drawing pen (7) from the drawing pen magazine (5) (FIG. 2).
