PURPOSE:To provide a rectilinear condensing type X-ray spectroscope capable of arranging a large number of spectroscopes around an X-ray generating point and capable of preventing the falling of a spectral crystal part. CONSTITUTION:A rectilinear condensing type X-ray spectroscope is equipped with a guide shaft 17 attached to the shaft D on a truck 7 at one end thereof in a revolvable manner, a gear mechanism 12 cooperating the truck 7 and the guide shaft 17 so that the angle acute angleND' formed by the axial line of the guide shaft 17 and a straight line A-A'' always become twice the angle acute angleADB formed by the straight line B-D connecting both ends of a guide member 8 and the straight line A-A'', the truck 19 guided by the guide member 18 and also guided along the guide shaft 17 in a slidable manner to be set to the crossing position of the guide member 8 and the guide shaft 7 and the detection slit C provided to the truck 19 so as to be directed toward the central part B of a spectral crystal 9. |
