<P>PROBLEM TO BE SOLVED: To provide a rolling device for inspection of spheres that simultaneously rolls a plurality of spheres to find a defect in a sphere, such as a defective color, a flaw, or the like, and that can be manufactured easily at a low cost and also can deal with a change of a sphere diameter. <P>SOLUTION: A rolling device for inspection of spheres includes: a board for mounting a plurality of spheres 55; an inner frame 30 of a quadrangular shape for arranging the plurality of spheres 55 in a plurality of vertical and horizontal rows inside the inner frame 30; and an outer frame 70 of a quadrangular shape larger than the inner frame 30, for guiding the inner frame 30 in vertical and horizontal directions while bringing the inner frame 30 into sliding contact with the inside of the outer frame 70. The outer frame 70 has a size enough for the inner frame 30 to move the spheres 55 each at a distance of at least one rotation of the sphere in vertical and horizontal directions. <P>COPYRIGHT: (C)2013,JPO&INPIT |
