Claim:
1. An arm type three-dimensional measuring machine comprising: a multi-jointed arm mechanism comprising a probe in a distal end; a processing part for computing a position of said probe; and an inclinometer configured to detect an inclination amount of a base part from a vertical direction in the base part for supporting the multi-jointed arm mechanism, wherein the processing part computes a position of the probe using the base part as a criterion and corrects the position of the probe using the base part as the criterion in a time-series manner based on an output from the inclinometer, wherein a time-series correction of a position of the probe using the base part as a criterion is made by a coordinate transformation matrix, obtained from the inclination amount, between a gravity coordinate system using the vertical direction as a criterion and a base part coordinate system using the base part as the criterion.
