Typewriter ribbon cassettes with multiple typing tracks

A typing ribbon cartridge for typewriting and/or printing machine comprising a housing with a housing base and two housing side-arms, and a typing ribbon with a free ribbon section outside the housing between the two housing side-arms, each housing sidearm having a guide piece lying in a plane which is parallel to the plane of the free ribbon section, the guide pieces having guide edges facing outwardly away from one another and over which the typing ribbon is passed by means of guide elements the guide elements being movable in the plane of the free ribbon section transverse to the longitudinal axis of the free ribbon section in order to move the free ribbon section to different positions for selecting one of several typing tracks, the typing ribbon cartridge being characterized by the fact that the guide edges of the guide pieces are straight and are perpendicular to the longitudinal axis of the free ribbon section throughout their entire length, and by means tiltably mounting the guide elements on the guide edges in such a way that they are tiltable relative to the guide pieces about axes which are perpendicular to the plane of the free ribbon section and which intersect the guide edges, whereby tension of the ribbon edges for different positions of the free section of the ribbon is equalized.
