ABSTRACT:
A ribbon cartridge may contain a single color ribbon or a multicolor ribbon, and is of wide U construction with a first pair of aligned (coaxial) pivot pins extending away from sides at locations therefrom remote from the legs of the U; a second pair of pins extends also from the sides and parallel to the first pair of pins; finally, a pair of support projections extend from the legs and also in opposite directions from the sides; the printer has two pivot mounts for receiving the pins of the first pair to thereby mount the cartridge, permitting pitch-like pivoting; in addition, the printer contains either (a) a second pair of mounts open from above for receiving the pins of the second pair, and thereby mounting the cartridge in a fixed position for single color printing, or (b) a cam shaft with at least one cam of different radial dimensions for engaging at least one of the projections such that upon turning of the cam a variable pivot-pitch is imparted upon the cartridge, the pins of the second pair being unimpeded.
