ABSTRACT:
A tape cassette for insertion into a tape deck to control misfeed tape includes a guide bracket mounted within a housing of the tape cassette to guide the tape along a tape feed direction between hubs. The guide bracket includes at least a V-shaped tape build-up area that is angled away from the tape to provide an area for build-up of loops of the misfeed tape. In addition, a curved rib can be included on the guide bracket to assist in the build-up of misfeed tape in the form of loops in the V-shaped tape build-up area. Also, a straight rib can be provided on the guide bracket to deflect tape that passes by the curved rib entering into a capstan chamber, back into the V-shaped tape build-up area. In accordance with the invention, the loops of misfeed tape build-up in a direction towards a pinch roller so that the pinch roller is pressed out of engagement with the capstan to stop the feeding of tape and prevent escape of misfeed tape out of the cassette.
