にしている。A three-dimensional data input device according to the present invention uses a sphere for allowing an operator to freely rotate around three axes and to detect the rotation, and supports the sphere. In addition, a small ball was used to detect the rotation angles of the sphere around three axes. Since the sphere is not mechanically constrained at all, the sphere is sucked at a negative pressure by a suction nozzle to prevent the sphere from shifting from a predetermined position.

らないようにする。The sphere 1 is a light hollow small sphere having a diameter of about 3 to 10 cm. Then, three small balls 2 having a diameter of 1/3 to 1/5 of the spherical body 1 are arranged in a triangular shape to hold the spherical body 1. The small ball 2 is provided with a sensor 3 for detecting the two-dimensional rotation of the small ball by the same mechanism as a normal trackball. Then, outputs of these sensors are input to the arithmetic unit 4. The arithmetic unit multiplies the arrangement of the small balls 2 by a coefficient determined by the direction and sensitivity of the rotation sensor 3 of the small balls 2 and performs addition and subtraction to determine the rotation angle of the spherical body 1 about three axes. Also,
In order to reliably contact the sphere 1 with the small ball 2, a suction nozzle 5 is provided near the center of a triangle having the small ball 2 as an apex, connected to a negative pressure generator 6 to suck air, and A negative pressure is applied to the space between the suction nozzle 5 and the suction nozzle 5 so that the sphere 1 does not rise from the small ball 2.
