A multi-axis type three-dimensional measuring apparatus includes a multi-axis arm mechanism, a probe formed in a distal end of the multi-axis arm mechanism and configured to measure a workpiece, and a projector formed in the distal end of the multi-axis arm mechanism and configured to scale a range of a projected projection image according to a distance between the workpiece and the probe. The projector is configured to project full-scale projection graphics of said workpiece so as to match the full-scale projection graphics with the workpiece regardless of a difference in a distance between the workpiece and the probe, and to project display information identifying a measurement schedule position by the probe.
