PROBLEM TO BE SOLVED: To provide a rotary table with such a simple structure as capable of smoothly rotating a disk which rotates with an object on it by omitting a rotating shaft structure for supporting the rotary table. SOLUTION: (1) One center of rotation is set in the rotary table to be rotated for disposing an appropriate number of rollers on the rear side of the rotary table rotated on a base board. (2) A line segment is drawn from the center of rotation to the position where each roller is set. (3) A line segment orthogonally crossing the line segment in the radial direction is drawn at the position where the roller is set, and the direction of rotating shaft of the wheel of the disposed roller is adjusted to the line segment in the radial direction, and the direction of rotating/moving of the wheel is adjusted to the orthogonally crossing line segment. The rotary table of this invention can be provided by disposing the rollers according to the above three steps. COPYRIGHT: (C)2007,JPO&INPIT
