Claims (1)

[Scope of utility model registration request] (1) A rotated sphere arranged to be freely rotatable, a first driven roller that is in contact with the rotated sphere and rotates by the rotational force of the rotated sphere, and a first driven roller that is in contact with the rotated sphere and rotated by the rotational force of the rotated sphere. a second driven roller whose axial direction is substantially orthogonal to the axial direction of the first driven roller; and a first rotation angle that detects the rotation angle of the first driven roller. and a second rotation angle detection means for detecting a rotation angle of the second driven roller, and in which the rotated sphere rolls on a base, the surface roughness of the rotated sphere is approximately An X-"Y" direction input device characterized in that it is regulated within a range of 5 to 20μ. 1 (2) In the utility model registration claim (1), the rotated sphere is a steel ball. 1. An x-y direction input device.
