However, in the conventional two-dimensional scanning X-ray analyzer having the above-mentioned structure, the sample stage is set to X-ray.
The analysis was performed by moving the sample in the Y direction. For example, when the sample placed on the sample table is moved quickly, the shape or the like is broken to cause trouble (for example, a living body with an open abdomen) or a liquid. In the case of a heavy object, the analysis was performed by moving the sample stage at a low speed, so that the analysis time was prolonged. Further, if the sample stage is to be moved at a high speed, not only a motor having a high power is required, but also the analysis accuracy may be deteriorated. Because of the dramatic rise, it was very difficult to speed up the sample stage.
