Latest Patents

One of Nakahata's latest patents is for a stationary game machine. This machine responds to player steering to change the orientation of a dummy mover, such as a vehicle, and translates the dummy mover in a direction crossing its path of movement. The game machine features a stationary vehicle and an endless belt representing a road. As the scenes on the road change with the movement of the belt, players can rotate a steering wheel to adjust the vehicle's orientation and translate it in a transverse direction. The translation is achieved through a rotating shaft and a pressure roller, generating thrust for the vehicle's movement.

Another patent involves a game machine that includes several movable assemblies designed to simulate animals. Each assembly features a pair of members that mimic the jaws of the animal. One jaw member is pivotally supported to simulate the opening and closing of the mouth. A mechanism applies a biasing force to open the mouth, while an external force can close it. A hitting sensor detects when the mouth closes and registers a score, returning the assembly to its home position.
