ABSTRACT:
A multicolor ink ribbon cassette comprises a cassette case containing a multicolor ink ribbon having plural lengthwise extending stripes of differently colored ink. A transfer roller transfers differently colored inks supplied from the wicks of respective ink cartridges to the ink ribbon stripes as the ink ribbon advances lengthwise through the cassette case. To reduce the thickness of the cassette case, the ink cartridges are all disposed in a common plane in angularly spaced relation about the transfer roller. At least two of the ink cartridges have the same shape and are arranged in the cassette case in upside down relation with respect to each other.
