Claims

[Claims for Utility Model Registration] (1) The object to be measured placed on the stage and the detector attached to the tip of a spindle supported movably in the vertical direction on the main body structure in a three-dimensional direction. In a motor-driven coordinate measuring machine that measures the shape, dimensions, etc. of the object to be measured based on the amount of relative movement and displacement when both are involved, a foreign object may be located at a certain distance on the tip side of the spindle. A sensor that detects the approach of a foreign object when it approaches is provided on the outer circumferential surface and/or the bottom surface that intersects the horizontal direction of the spindle, so that it is possible to detect the approach of a foreign object from the horizontal direction and/or from below. A motor-driven three-dimensional measuring machine including a safety device including an emergency stop device for forcibly stopping relative movement between the object to be measured and the detector using an output signal. (2) In paragraph 1 of the claims for utility model registration,
The sensor is composed of an optical fiber sensor in which a set of optical fibers for emitting and receiving light are arranged close to each other, and the optical fiber sensor is arranged on the outer circumferential surface and/or lower surface of a flange provided on the spindle that intersects in the horizontal direction. A motor-driven three-dimensional measuring machine characterized by multiple locations arranged at equal angles.
