ABSTRACT:
A tape cassette includes supply reel and a takeup reel each with a plurality of notches arranged along the entire outer circumference of the lower flange of the reel. A plurality of projections are provided on a lower housing of the cassette for engaging the plurality of notches, and a resilient member is provided in an upper housing of the cassette for biasing the supply reel and the takeup reel toward the lower housing, causing the notches to engage the projections to form a lock for preventing rotation of the reels when the tape cassette is not in use.
