Abstract
A tape cassette including a rib projecting upwardly from a bottom wall of a cassette case at a position between the center and one side of a tape drawing recess formed at the front of the cassette case, the rib being disposed close to the back surface of the tape, and a projection that projects from a back lid which, in a closed position, protects the back surface of the tape. When the back lid is rotated to reach an open position, the projection is kept in contact with an upper end of the rib. Accordingly, even when a part of the tape is lifted by the back lid during a lid opening operation, the tape is prevented from entering behind the rib, thereby also preventing tape jamming and damage to the tape player.
