<p>PURPOSE: To provide a space coordinate detector which enables highly accurate detection of not only relative angle of inclination and angle of rotation of a light emitting part and a detecting part with respect to the axis connecting both the parts but also relative distances in the directions of X axis, Y axis and Z axis between both the parts with a simple structure. CONSTITUTION: A light emitting section 10 is arranged in an equipment body having a screen and a detecting section 11 arranged in an operating member manipulated by an operator. The light emitting section 10 is provided with three light sources 12, 13 and 14 emitting light allowed to be identified from each other so that the straight line connecting the light sources 12 and 13 is orthogonal to the straight line connecting the light sources 13 and 14. The detecting section 11 is provided with first and second photodetectors 18 and 19 as arranged along the direction of the Y axis when the Z axis extending ahead thereof and X-Y rectangular coordinate orthogonal thereto are set, a third photodetector 20 disposed at a position deviated in the direction of the X axis from the second photodetector 19 and three stop openings 16a-16c disposed ahead of the photodetectors 18-20.</p> |
