ABSTRACT OF THE DISCLOSURE Mechanism for supplying golf balls fully automatically to tees of a driving range, exactly and without delays, for each of several players practising simultaneously, according to the driving of the golf balls by the players. An inclined main flow path is connected to a ball reservoir, and several inclined branch flow paths are connected in parallel to the main path. There is a first vane valve within a ball discharging device, that opens and closes the main flow path, and a second vane valve within each of several flow change-over devices that opens and closes the paths from the main to the branch flow paths. A parallelogram link within a ball serving device, connected to the branch flow paths, raises each ball to a position where it can be driven. An electric eye detects if a ball is present on a tee or not. When balls are short in a branch flow, an electric signal is made to a control circuit by the operation of a ball level inspection device. There are electromagnetic solenoids for activating the first and the second vane valves, and for activating the parallelogram link; a switch in the inspection device and a photo-electric relay, activated by the electric eye, are connected in an electrical circuit.
