Patent abstract
An inspection apparatus includes: an upstream imaging mechanism that images an upstream wall surface extending from a bottom part of a recess upstream of and adjacent to a projection in a rotating direction of a workpiece to a tip of the projection; and a downstream imaging mechanism that images a downstream wall surface extending from a bottom part of the recess downstream of and adjacent to the projection in the rotating direction to the tip of the projection. At least one of the imaging mechanisms includes a mover for parallelly moving and positioning in an orthogonal plane orthogonal to the axis of symmetry and images the workpiece from a position radially outward of the workpiece and positioned by the mover.
