Abstract
A tape printer cassette, bearing a film tape and ink ribbon on spools therein, maintains the film tape in a feed path defined by an outer wall and a partition and the ink ribbon in a feed path defined by the partition and an inner wall. The inner wall and the partition are set to be substantially the same height as the ink ribbon and higher than the outer wall. When the ink ribbon is wider than the film tape, an unused portion of the ink ribbon remains after printing; regulating members spaced by the width of the film tape, downstream of the printing region, keep the film tape in the center of the ribbon so that the unused portion remains and so that the ink ribbon cannot proceed along the film tape feed path past the regulating members. When an adhesive backing is also provided on a spool in the cassette, regulating members align the film tape and adhesive backing at a feed capstan so that they are not displaced relative to each other when adhered.
