Abstract
A split mold for vulcanizing a tire is held at a mold holding section, which is held on a rotatable base, and then a measuring section measures distances to an inner surface of the split mold in the inside diameter direction and in the axial direction. An operating section acquires two-dimensional geometric data of the inner surface of the split mold from the distances measured above, and further acquires geometric data over the entire circumference by rotating the rotatable base, and the data are combined to acquire three-dimensional geometric data of the inner surface of the split mold and make reference geometric data for tire inspection.
