Patent ID: 8852506

Claim:
A sample analyzer comprising: a specimen preparation section that includes: a first reagent container containing a first reagent, a second reagent container containing a second reagent, and a sample container including a blood cell, wherein the specimen preparation section prepares: a first measurement specimen from the first reagent contained in the first reagent container and the sample including a blood cell, and a second measurement specimen from the second reagent contained in the second reagent container and the sample, wherein the first reagent container includes a first recording medium storing a first reagent information indicating the first reagent, and the second reagent container includes a second recording medium storing a second reagent information indicating the second reagent; a detecting section that includes a flow cell into which the first and second measurement specimens are introduced, wherein the detecting section detects the blood cell from the first measurement specimen, the second measurement specimen, or both passing through the flow cell; a first container set section that receives the first reagent container; a first cover that moves to a first open position where the setting of the first reagent container in the first container set section is permitted and a first closed position where the setting of the first reagent container in the first container set section is not permitted; a first detector that detects a movement of the first cover to the first open position; a second container set section that receives the second reagent container; a second cover that moves to a second open position where the setting of the second reagent container in the second container set section is permitted and a second closed position where the setting of the second reagent container in the second container set section is not permitted; a second detector that detects a movement of the second cover to the second open position; a first information reader that reads information from a recording medium of a reagent container set in the first container set section; a second information reader that reads information from a recording medium of a reagent container set in the second container set section; an output section; and a controller programmed to: control the output section to output a predetermined notification, if the second detector detects the movement of the second cover to the second open position when it is required to set the first reagent container in the first container set section; and control the first information reader to start reading the information when the first detector detects a movement of the first cover to the first open position.
