Abstract (en)
[origin: WO0103948A1] The invention relates to a multi-cartridge writing instrument. According to the invention, the cartridges (6) are placed on a shaft (20) of an actuation button (23) that protrudes from a slot (7) of the shaft (3) of the writing instrument. The interior of said actuation button (23) is provided with a catch element (24) that engages with a catch surface (41) in the writing position. If a change of color is desired, a central push button (35) is actuated which causes the catch surface (24) to butt against a conical surface (18) and to be displaced outwardly while disengaging it from the catch surface (41). The inventive writing instrument is characterized by a simple mechanism for actuating the cartridges and is inexpensive in its production.
