To provide an X-ray fluorescence spectrometer of a simplified structure of a type in which a sample can be transported to an irradiating position where the sample is irradiated with primary X-rays and analysis can be achieved by positioning a target area to be measured of the sample. When an r drive means drives an r drive shaft , a transporting function of transporting the sample and a positioning function of positioning the target area in an r direction are performed. Also, a&thgr; drive shaft of a &thgr; drive means for performing the positioning function for positioning the target area in a &thgr; direction and the r drive shaft of the r drive means form a dual coaxial shaft assembly.

X-ray fluorescence spectrometer

An analyzer system to ease sample handling having a sample exchanger with an analyzer apparatus, a sample table, and a transfer unit for taking the sample from the table into the analyzer apparatus. The sample table includes a base and a tray for holding the samples supported so they tray can be pulled out in front of the base. With this, it is possible for an operator to handle the samples easily, in particular samples located deep on the table usually difficult to handle. The operator may pull out the tray in the front direction from the base, without having to stand. The tray may be separately carried to a computer controller of the analyzer apparatus, thereby enabling input of sample data while mounting or installing the samples onto the tray to prevent erroneous inputting.
