Abstract: In a device for controlling the drive of mechanisms operating separately from one another, the object is to minimize the operating effort and expense of driving alternatively operating mechanisms. Furthermore, it is ensured by the device that the mechanisms are only allowed to be put into operation if they are in a specific state and that this state is maintained throughout their operation.
