PROBLEM TO BE SOLVED: To obtain a detector position adjustment mechanism whose structure is simple and manufacturing cost is low. SOLUTION: In a detection structure, a scale 4 is arranged on either a measuring device body 3 or a movable table 2 which can be moved to the device body 3, and a detection bracket 6 of a detector 8 for detecting the scale 4 is attached on the other side of the device body 3 and the movable table 2. Penetrating holes 9L, 9R into which a pair of fixing bolts 5L, 5R can be inserted are formed on the detection bracket 6, and corresponding screw holes 10 are formed on either the device body 3 or the movable table 2, respectively, on which the detection bracket 6 is attached. An adjustment hole 11 is formed into which an adjustment screw 12 can be screwed. The adjustment screw 12 can abut against a peripheral surface of the corresponding fixing bolt 5R, facing the one penetrating hole 9R whose diameter is made greater sufficiently than outer diameters of the fixing bolts 5L, 5R. The detector position adjustment mechanism is thus constituted. COPYRIGHT: (C)2004,JPO
