Abstract: A control unit outputs measurement status information including the time up to the completion of creation of the calibration curve for each of the desired measurement items to a display unit. The output/display of the calibration curve data measurement status for each of the items enables the operator to be aware of information about a failure to set a standard solution or to request the setting of the standard solution and to recognize how long he or she will need to wait until the creation of the calibration curve begins. The operator can therefore know what can be done while waiting, thereby improving job efficiency.

Abstract: In an automated analyzing apparatus, problems arise when a reagent container is carried in during analysis, since it is necessary to stop all accesses of mechanisms etc. to a location of the apparatus where the reagent container is placed and, in a situation in which measurements have been already started, it is impossible to carry the reagent container after waiting about several minutes. To address the problems, when a remaining amount of a reagent corresponding to a predetermined item becomes equal to or less than a first threshold value, a pause cycle of reagent suction is generated in which the reagent dispensing mechanism does not suction the reagent from inside of a reagent container of a reagent disc at regular intervals, and a reagent container containing the same kind of reagent in the reagent disc by the reagent container carrying mechanism is automatically carried in the pause cycle.

Abstract: A detergent reservoir reserves detergent for cleaning of a sample probe and includes a cleaning liquid supply port, a detergent supply port, and a waste liquid port When a predetermined condition for execution of cleaning of the detergent reservoir is not satisfied, and a remaining amount of the detergent reserved in the detergent reservoir is a predetermined amount or less, a pump is operated to increase the remaining amount of the detergent to the predetermined amount; and when the predetermined condition for execution of cleaning of the detergent reservoir is satisfied, a solenoid valve is opened to dispose of the detergent in the detergent reservoir. Then, after the detergent in the detergent reservoir is disposed of, the solenoid valve is closed, and a pump is operated to supply cleaning liquid to the detergent reservoir.

Abstract: An automatic analyzer enables users to perform working steps easily and reliably by switching a display screen irrespective of a skill level of the user. The automatic analyzer, which determines a consistency of a test item, includes a display/input section to display a plurality of working steps relating to necessary work flow for measurement. The display/input section is adapted to selectively present a maximized workflow display and a reduced workflow display. The maximized workflow display shows a series of operations and works, and further shows a plurality of operations and works in an order that the plurality of operations and works are processed. In a reduced display of the work flow, the reduced workflow display shows details of a specific operation or work, and a position of the specific operation or work in a sequence that the entire series of operations and works are processed.

Abstract: Provided is an automatic analyzer capable of performing measurements efficiently. The automatic analyzer comprises: a first reagent disk on which reagent packs each storing a reagent to be used for a reaction are placed; a second reagent disk; and a reagent pack transfer mechanism which transfers the reagent packs between the first reagent disk and the second reagent disk. A judgment unit and a drive control unit of a computer operate to transfer a reagent pack that has been placed on the second reagent disk to the first reagent disk using the reagent pack transfer mechanism, perform at least quality control measurement out of the calibration and the quality control measurement with the reagent stored in the reagent pack transferred to the first reagent disk, and thereafter return the reagent pack to the second reagent disk using the reagent pack transfer mechanism.

Abstract: When dispensing from one specimen is repeated, the cleaning liquid adhering to an outer wall of a cleaned dispensing nozzle is likely to be moved into a sample vessel during aspiration of the sample and result in reduced sample concentration or deteriorated analytical accuracy. Thus, the cleaning mechanism has a cleaning range of the dispensing nozzle outer wall which is changed according to a range in which dirt adheres to the nozzle. Additionally, an ejector effect acting between the dispensing nozzle and a cleaning liquid flow prevents a decrease in the concentration of the sample by reducing the amount of cleaning liquid which adheres to the dispensing nozzle outer wall. The cleaning mechanism also uses a liquid level detection function of the dispensing nozzle and a nozzle pipe internal-pressure change detection function to determine a discharge state of the cleaning liquid flow and obtain an appropriate cleaning range.
