ABSTRACT:
A tennis training device having a ball emitter including a ball emitting cylinder is disclosed. In this case, a device is provided for controlling horizontally and vertically inclined angles of the ball emitting cylinder. This controlling device is composed of a supporting member for the ball emitting cylinder, two low speed motors each rotatable in forward and reverse directions, links for connecting the supporting member to the two motors, respectively. An electric power supply source is connected to the two motors for supplying input current to the two motors, and a remote control panel is connected through the electric supply source to the two motors, includes change-over switches for changing over the input to the two motors and rotates the ball emitting cylinder in horizontal and vertical directions so as to control horizontally and vertically inclined angles of the ball emitting cylinder.
