Patent ID: 7186186

Claim:
A spherical object drop mechanism for game apparatus, comprising: a housing into which at least one ball is stored to be later dropped to ground; a ball passage that is a cylinder provided to said housing having an opening diameter size that is slightly larger than a diameter of a ball to be used; an upper cogged stopper that is located in an upper position of said housing near said ball passage as to cut across a part of said ball passage, the upper cogged stopper having a hollowed portion that matches a part of a ball's diameter; a lower cogged stopper that is located in a lower position of said housing near said ball passage as to cut across a part of said ball passage, the lower cogged stopper having a hollowed portion that matches a part of a ball's diameter; and a gear wheel having teeth that engage with a cogged portion of at least one of said upper and lower cogged stoppers; wherein a positional gap exists between said hollowed portion of said upper cogged stopper and said hollowed portion of said lower cogged stopper such that when said upper cogged stopper allows a ball's movement, said lower cogged stopper stops the ball's movement, and when said lower cogged stopper allows a ball's movement, said upper cogged stopper stops the ball's movement.
