First Claim
1. A sample analyzer for analyzing a sample using a reagent in a reagent container comprising:
- a first reagent container holding unit configured to hold a first reagent container attached with a first electronic tag recorded with reagent information regarding a reagent;
a second reagent container holding unit configured to hold a second reagent container attached with a second electronic tag recorded with reagent information regarding a reagent;
a reagent information reading unit which comprises an antenna portion configured to emit an electric wave to the first electronic tag and the second electronic tag and to receive a response electric wave from the first electronic tag and the second electronic tag, and which reads the reagent information recorded in the first electronic tag and the reagent information recorded in the second electronic tag based on the response electric wave received by the antenna portion from the first electronic tag and the second electronic tag;
a control unit configured to control the reagent information reading unit,a detector configured to measure a component contained in a measurement sample prepared from the sample and at least one of the first reagent and the second reagent; and
a drive unit configured to move the first reagent container holding unit and the second reagent container holding unit,wherein the first reagent container holding unit holds a plurality of first reagent containers and is formed to a substantially circular shape in a plan view;
wherein the second reagent container holding unit holds a plurality of second reagent containers and is formed to a substantially circular shape on an inner peripheral side of the first reagent container holding unit in the plan view,wherein the antenna portion is arranged on an outer peripheral side of the first reagent container holding unit,wherein the drive unit is configured to move the first reagent container holding unit to locate the first electronic tag of the first reagent container at a position facing the antenna portion when the first electronic tag is a read target,wherein the drive unit is configured to move the first reagent container holding unit to locate a gap between first reagent containers held adjacent to each other at a position facing the antenna portion and to move the second reagent container holding unit to locate the second electronic tag of the second reagent container at a position facing the antenna portion when the second electronic tag is the read target,wherein the control unit controls the reagent information reading unit to cause the antenna portion to emit an electric wave of a first reaching range to the first electronic tag, and to emit an electric wave of a second reaching range greater than the first reaching range to the second electronic tag, andwherein the antenna portion is attached to a housing of the first reagent holding unit.
