Abstract
A cassette recorder employs a locking device for the mode selection buttons in order to retain selected modes, where the device can release the selected mode by operation of a stop button. An ejector mechanism is also associated with the stop button so that operation of the stop button can effect unlocking of the cassette holding pocket.
