Abstract: A sample measuring apparatus according to one or more embodiments is disclosed. The apparatus may include the sample rack storage in which the sample rack holding the sample container is installed, the reagent rack storage in which the reagent rack holding the reagent container is installed, an information reader, and a first flection unit. The sample rack storage is geometrically placed at a position farther from the information reader than the reagent rack storage. The information reader reads the sample identification information of the sample container from the first reflected light acquired via the first flection unit, and reads the reagent identification information of the reagent container from the second reflected light acquired not via the first flection unit.
