ABSTRACT:
A drive mechanism for cassette tape recorders is disclosed wherein first and second reel bases are rotated in opposite tape take-up directions to pull in the slack of a tape after a cassette is loaded and an electrical power is turned on. After the tape slack is removed, a drive and transmission mechanism is changed into a playback state. A detector is employed to detect the stoppage of tape run as a result of pulling in the tape slack to actuate release means which selectively disconnects one of two transmission means to first and second reel bases from a drive unit.
