Abstract
An inspection apparatus for inspecting a workpiece having an outer peripheral portion rotationally symmetric about a symmetry axis with projections and recesses provided periodically and repeatedly, the apparatus comprises: an edge imaging mechanism that captures an image of an edge portion of a projection of a rotated workpiece; an upstream imaging mechanism that captures an image of an upstream wall surface of the rotated workpiece; and a downstream imaging mechanism that captures an image of a downstream wall surface of the rotated workpiece. The inspection apparatus inspects the workpiece on the basis of the images captured by the edge imaging mechanism, the upstream imaging mechanism, and the downstream imaging mechanism.
