ABSTRACT:
Two column-shaped ribs are disposed between a ribbon spool and an inner wall of a lower case in a cassette case. When a film tape is an ink-receiving type, which needs an ink ribbon, a pathway traveling to the outside of the ribs is selected so that the film tape traveling through the case can be reliably prevented from contacting the ink ribbon wound around the ribbon spool. On the contrary, when the film tape is a heat-sensitive type, wherein printing is performed by a thermal head directly heating the film tape, a pathway which travels between the ribs is selected so that the tape can be prevented from being drawn back when the tape is flexible like paper.
