Auto-repeat mechanism for cassette tape recorder

An auto-repeat mechanism for a cassette tape recorder including fast forward and rewind levers on a chassis and take-up and supply reel bases rotatably installed on the chassis, which comprises

• a fast feed unit pivotally mounted on the chassis for selectively transmitting rotational force to the take-up or supply reel base in response to actuation of the fast forward or rewind lever,
• an auto-repeat lever pivoted to the chassis,
• means associated with the auto-repeat lever for biasing said fast feed unit into cooperation with the supply reel base to provide rewind operation,
• means for positively displacing said fast feed unit to a neutral position against the biasing force during playback operation, and
• means associated with the take-up reel base for detecting the end of a tape, said detecting means being operatively connected to said positive displacing means,
• wherein with the auto-repeat lever actuated, the positive displacing means keeps said fast feed unit in the neutral position during the playback operation, and when the detecting means detects the end of the tape, the detecting means cancels the positive displacing means, thereby allowing said biasing means to move the fast feed unit into the rewind position.
