ABSTRACT:
A tape cassette includes reel hubs rotatably received in the housing of the cassette, each reel hub being formed with a recess. The recess includes an opening at its lower end and reel pawls therein are adapted to engage with pawls of a reel drive on a reel base. The recess further includes a cylindrical-shaped portion disposed below the reel pawls and a conical-shaped portion disposed below the cylindrical-shaped portion, one of which portions is caused to engage with an engaging surface of the reel base of the reel drive on the reel base, thus enabling the centers of the reel hub and the reel base to correspond with each other.
