ABSTRACT:
A sound dubbing control for a videotape recorder includes a mechanism which enables it to be automatically locked in operating condition when the playback control is subsequently actuated; the dubbing control is automatically released when the playback control is released. The dubbing control and playback control each include a slidable member one of which moves transversely with respect to the other and the member for the dubbing control is provided with a leaf spring having parallel arms. One of the arms has a hook-shaped end which catches on a projection on the playback member when the dubbing member is advanced into the path of the playback member. This action also causes the other arm of the spring to actuate a switch controlling the sound dubbing circuit.
