This invention relates to a game board whereby a mimic tennis game can be played. Two animated racket-supporting bodies disposed opposedly to each other across a play board are moved alternately so as to catch a ball which comes rolling on the board surface toward either side of the board where said racket-supporting body is disposed, and when the racket carried by the racket-supporting body on one side catches the ball and the racket is accordingly displaced, the racket driving mechanism provided in the racket-supporting body is operated to drive the racket so that it will automatically hit the ball. After hitting of the ball by the racket, the racket driving mechanism is inactivated. As the animated bodies are moved across the play board, a pinion gear meshes with a rack gear and ultimately a spring is wound up to accumulate power for driving the simulated tennis ball. Each time a ball is hit, a bell rings. The tennis racket carried by each animated body is actuated by a spring driven mechanism including a cam plate formed with a curved groove and a follower connected to the cam plate. A half spherical member is slidable in a slot marked with numerical figures to provide a score indicator.
A tennis game board mounted with the animated racket-supporting bodies disposed opposedly to each other across the board surface, each of said racket-supporting bodies having provided therein a main shaft and a racket driving shaft to which a racket is secured, said main shaft having mounted thereon a cam plate formed with a curved groove designed to convey to said racket a movement for striking a ball rolling down on the board surface and a windup spring adapted to transmit rotative force to said main shaft, said racket driving shaft having joined thereto an end of a follower whose other end is connected to said cam plate.
