ABSTRACT:
A tape cassette includes tape reels and a cassette main body formed of an upper shell and a lower shell. In such a tape cassette, a tape reel position restricting portion serving as a reinforcing member for the lower shell is provided on the lower shell at a position outside an outer periphery of the lower flange. The tape reel position restricting portion includes a high rib; an intermediate rib being lower than the high rib within a range not to obstruct passing of a tape end detecting light beam, and being positioned in a tape end detecting light path; and a low rib being lower than the intermediate rib, and being positioned in a tape path region. The intermediate rib and the low rib are preferably disposed outside the high rib.
