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.

Drive mechanism for cassette tape recorders

A tape stop detection mechanism for cassette tape recorders is disclosed. The tape recorder includes two reel bases driven by a suitable drive and two reel shafts mounted in a usual slip-drive manner on the reel bases. Two slip plates are provided about the reel shafts so as to be displaced upon rotation of the reel shafts, a detection lever is connected at either end with said slip plates so that the lever is also displaced when at least one of the reel shafts is rotated, and cam means is provided which cooperates with the detection lever only when the lever is restored as a result of stoppage of the reel shafts. In response to the cooperation of the cam means with the detection lever, the rotation of the reel bases is interrupted or the rotating direction of a given reel base is reversed.
