PURPOSE:To position a reel member to a specified height and with a simple constitution, by forming a part of the reel member with a magnetic material and absorbing the reel member by a magnet provided at a reel drive disk for positioning. CONSTITUTION:At least a part of a reel hub 6 incorporated into a tape cassette is formed with a magnetic material. The hub 6 is put on a magnet 11 provided to a reel shaft 9 and absorbed by the magnetic force of the magnet 11 to be positioned at a certain height, e.g., at the center place inside a cassette case. This center position has no change although the height of the cassette case has a change owing to the variance of the measurement. |
