Abstract
A tape recorder of the cassette type is operated by a push button system employing cam surfaces and pins engaging and locking the respective buttons in the operational state. The buttons may be released by a stop mechanism actuated either manually by a push button or automatically by an autostop mechanism when the end of the tape is reached. The autostop mechanism also includes a tape slack prevention device operable to brake a reel of the recorder during pausing.
