Abstract
A manual three dimensional coordinate measuring machine has a probe manually movable along three orthogonal coordinate axes, X, Y and Z, and a Z axis member supporting the probe. The size and shape of a workpiece is determined by displacements along the three axes from a predetermined origin when the probe contacts the workpiece. The manual coordinate measuring machine further includes a slide ring positioned at the bottom side of the Z axis member and at least one elastic member. The slide ring is movable in an arbitrary direction relative to the Z axis and along the Z axis. The slide ring is held at a predetermined position in the plane and along the Z axis by the at least one elastic member. The at least one elastic member allows the slide ring to move in the plane or along the Z axis by elastic deformation of the at least one elastic member in response to a force which is larger than a predetermined value.
