The controller is attached to one of the posts and comprises an electrically driven winch winding and unwinding the net cord cable for raising the net at the beginning of a game period and for lowering the net at the end of a game period. The electric motor is controlled by a coin or token operated switch and timer. The invention requires no modification or alteration of conventional existing net support posts.
