Claim:
An input device for a billiard game comprising: a simulative ball provided as an object to be shot by a player; a link portion having a ball axis on which the simulative ball is mounted; a support portion including a bearing base rotatable about a rotational axis running crosswise to said ball axis, the link portion being received to the bearing base so that the ball axis tilts over toward a shot direction which is directed crosswise to the rotational axis when the simulative ball is shot in said shot direction by rotation of said bearing base about said rotational axis, the link portion being engaged with the bearing base to be movable in a predetermined range linearly along an axial direction of the ball axis and rotatable around the ball axis in a manner permitting the simulative ball to spin thereabout, whereby both of a spinning motion of the simulative ball and a linear motion of the simulative ball along the axial direction of the ball axis are permitted; and a signal output device for outputting at least one signal that corresponds to operation of the link portion.
