Abstract

A coordinate measuring machine including a surface plate; a probe moving body; an INC pattern and ABS pattern along a moving direction of the probe moving body; an INC detector that outputs a plurality of waveform signals in accordance with the moving amount based on the INC pattern; an ABS detector that outputs an absolute position signal of the probe moving body based on the ABS pattern in response to a request signal; and a control device that has a INC counting portion that counts the waveform signals outputted by the INC detector; a position information obtaining portion that reads a counted value at a timing when a work is detected by a probe; and a presetting portion that emits the request signal to the ABS detector to obtain the absolute position signal, and presets the counting portion to this absolute position signal.
