ABSTRACT:
A reel drive apparatus is provided for driving the reels of a coaxial-reel tape cassette in fast forward or reverse. In one embodiment, as the cassette is placed on a tape recorder, a friction wheel mounted for rotation on a flexible shaft extending from the recorder locates in a space defined between a pair of concentric flanges mounted for rotation with respect to the reels. The friction wheel is disposed to alternately engage the concentric flanges and reversibly drive the reels. By securing each flange to a corresponding one of the coaxial reels, the tape is positively transported in either direction.
