<p>A tape cassette (1) includes a cartridge (2) and one tape reel (3) provided in the cartridge (2), with a recording medium in the form of a tape (10) being wound upon the tape reel (3). In the tape cassette (1), a leader tape (12) that is more rigid than the recording medium in the form of a tape (10) is connected to an unwinding end of the recording medium in the form of a tape (10); a toothed portion (a protrusion) is formed on at least a portion of both side edges of the leader tape (12); the tape reel (3) has a flange (5, 6) on a top portion and on a bottom portion of a hub (4), and feed teeth (7, 8) (engaging portions) that engage the protrusions of the leader tape (12) are formed on outer peripheral edges of the flanges (5, 6). Rotation of the tape reel (3) in one direction causes the engaging portions (7, 8) to feed the protrusions, whereby the leader tape (12) is sent out from the cartridge (2). The tape cartridge (2) can be reliably mounted on a recording/reproducing apparatus. <IMAGE></p> |
