Analyzing device

An analyzing device comprising:

• a cell switching mechanism that switches a measurement position where a measurement cell that houses a measurement specimen is located on an optical path and an evacuating position where the measurement cell is evacuated from the optical path and that is configured to make a first moving speed from the measurement position to the evacuating position different from a second moving speed from the evacuating position to the measurement position, and
• a distinguishing mechanism that detects first speed information relating to the first moving speed and second speed information relating to the second moving speed by the use of light used for measuring the measurement specimen and that distinguishes the measurement position and the evacuating position using a difference between the first speed information and the second speed information.
