According to the present invention, a three-dimensional measuring instrument includes a spindle that moves an object to be controlled in a predetermined axis direction; and a controlling device that controls a position of the object to be controlled by controlling a position of the spindle. The three-dimensional measuring instrument further includes an absolute-type linear encoder that outputs an absolute position of the spindle. With this, it is possible to start measurement by the three-dimensional measuring instrument in a short period of time.

Three-dimensional measuring instrument

A three-dimensional measuring machine (measurement device) which supplies a probe having a measurement head able to make contact with a measured object and a contact detection sensor which detects the contact of a measurement head with a measured object and outputs a touch signal; a displacement structure which displaces a probe along three axial directions orthogonal to one another; scale sensors which detect the position coordinates of a probe and output a coordinate detection signal; a control circuit board having an integrated circuit on which are installed a touch counter which counts touch signals and a scale counter which counts coordinate detection signals; and a latch controller which latches a touch counter value and a scale counter value at the same time.
