ABSTRACT:
An ink ribbon cassette has a case housing an ink ribbon inside. Holes for receiving positioning members are formed at the two ends of a front portion of the case, and an engaging member is formed at the center of a rear portion of the case. One of the positioning members also serves as an ink ribbon end detector. A printing apparatus for printing using such an ink ribbon cassette has a carriage, projections and a spring. Thus, the slackening of the ink ribbon will not occur in the printing mode.
