Abstract
An automatic repeat mechanism for a cassette tape recorder is disclosed which comprises a fast feed unit for selectively transmitting rotational force to a take-up or supply reel base in response to actuation of a fast forward or rewind lever; means for biasing the fast feed unit into cooperation with the supply reel base to provide rewind operation; means for positively displacing the fast feed unit to a neutral position against the biasing force during the playback operation; and means for detecting the end of tape supply. During the playback operation, the positive displacing means keeps the fast feed unit in the neutral position. After the detecting means detects the end of tape supply, the detecting means functions to cancel the positive displacing means, thereby allowing the biasing means to move the fast feed unit into the rewind position.
