Abstract
PURPOSE: To permit measurement of a three-dimensional geometry by detecting the displacement of a measuring shaft apparatus with respect to a casing when a bulb at the end of the measuring shaft apparatus and an object to be measured are brought into contact with each other.
CONSTITUTION: The measuring shaft apparatus of a geometry measuring apparatus A is fitted into a casing 26. Said measuring shaft apparatus is composed of a measuring member 32 having a bulb 34 at the end, a spherical bearing portion 44, a cylindrical bearing portion 46, a ball 52, a rod 56 and a spring 60 and freely supported with respect to a casing 30 through a centripetal action. The output of the geometry measuring apparatus A is converted into a binary-coded pulse train in a signal converter 64 and sent through a receiver 78 to a demodulator 82 and a code number coincidence identifier 84. When the coincidence of the pulse train and the predetermined code number is detected in the code number coincidence identifier 84, the outputs of limit switches 72 and 74 are read to perform measurement.
