发明名称 Game apparatus having a spherical object drop mechanism
摘要 A game apparatus has a mechanism allowing to drop spherical objects one by one on the desired positions on the ground. The spherical object drop mechanism includes a housing for storing a plurality of spherical objects to allow vertical movements of the spherical objects therein by their own weight, a first stopper provided in the housing for stopping the vertical movement of the spherical objects, a second stopper provided in the housing located at a location lower than the first stopper by the distance corresponding to the diameter of the spherical object for stopping the vertical movement or releasing the stop operation of the spherical objects, a stopper drive mechanism to operate the first stopper and the second stopper opposite to each other, and a knob to operate the stopper drive mechanism from outside.
