An automated analyzer for analyzing a sample, comprising:

• a measurement device configured to measure the sample;
• at least one sample tray provided outside the measurement device, the at least one sample tray being configured to receive a plurality of sample containers thereon;
• a rack configured to set the sample tray, wherein when the sample tray is set on the rack, the sample tray remains at a fixed position on the rack relative to the measurement device;
• a conveyance device configured to select one of the plurality of sample containers placed on the sample tray, convey the selected sample container to the measurement device, and after measurement by the measurement device, return the sample container to an original sample tray on which the sample container was originally placed;
• a control device configured to control an operation of the conveyance device;
• and
• a retreat portion provided at a position different from positions where the measurement device and the sample tray are provided, the retreat portion being configured to temporarily receive the sample container,
• wherein the control device causes the conveyance device to place the sample container at the retreat portion when the sample container is unable to be returned from the measurement device to the original sample tray, and
• wherein the automated analyzer is a fluorescence X-ray analyzer configured to analyze the sample by irradiating a surface of the sample with X-rays and detecting fluorescence X-rays generated from the surface.
