ABSTRACT:
A cassette transport lever is engaged by a cassette being inserted into the apparatus, for movement of the lever to an operating position; and upon subsequent reverse movement of the lever for ejecting the cassette. Upon movement of the lever to the operating position the lever engages a switch for turning on a motor which drives a control rod for controlling other apparatus functions. During ejection, guide surfaces on the control rod engage a delay element which holds the switch in the position for maintaining the motor turned on until the cassette is ejected past the position in which the motor was turned on during insertion. Upon the cassette reaching a second position, the guide surface releases the delay element so that the motor may be turned off. During insertion, the delay element engages a different portion of the guide so that the motor is only turned on when the ejection lever has been sufficiently rotated.
