  In the “item” column, analysis items “item A”, “item B”, “item C”, “item D”, and the like that can be analyzed are displayed. When the selection input for setting the inspection item of the sample to be stored in the sample container 11 at the holding position set in the “position” column is performed from the displayed inspection items, the selection input is performed. For example, “item A”, “item B”, and “item C” are identified and displayed.

  FIG. 6 is a flowchart showing the operation of the automatic analyzer 100. The sample container 11 that stores the test sample to be inspected whose holding position and inspection items are set on the general setting screen 73 of FIG. 5 is the rack with the number “1” of the sample rack 40 identified by the rack ID “1”. Held in position. Then, after the sample rack 40 holding the sample container 11 is placed at the standby position A1 on the belt 41 of the sampler unit 12 in the analysis unit 10, when the general measurement start input is performed from the operation unit 80, automatic analysis is performed. The apparatus 100 starts operation (step S1).

  The system control unit 90 controls the analysis control unit 50, the data processing unit 60, and the output unit 70 based on the input information set in the “position” and “item” fields of the general setting screen 73, and executes the analysis operation. Let The mechanism control unit 52 of the analysis control unit 50 operates each analysis unit of the analysis unit 10. The rack detector 44 of the sampler unit 12 detects the position of the sample rack 40 and the rack ID at the standby position A1 held by the belt 41 (step S2).

  If the rack ID detected by the rack detector 44 is the same as the rack ID set on the general setting screen 73, the process proceeds to step S3. If the detected rack ID is different from the rack ID set on the general setting screen 73, the process proceeds to step S8.

  The belt 41 moves the sample rack 40 detected by the rack detector 44 as having the rack ID “1” to the drawing position A2. The sample rack 40 moved to the drawing position A2 is moved in the L2 direction by the mechanism unit 51. The container detector 45 detects the sample container 11 held in the sample rack 40. The mechanism control unit 52 detects the rack position of the sample container 11 detected by the container detector 45 based on the detection signal from the container detector 45 (step S3).

  When the sample container 11 is not held in the sample rack 40 moved in the L2 direction, the process proceeds to step S8. When the rack position of the sample container 11 detected by the container detector 45 is different from the rack position set on the general setting screen 73, the process proceeds to step S8.

  The sample dispensing probe 21 puts the test sample in the sample container 11 detected by the container detector 45 held at the rack position of the number “1” of the sample rack 40 stopped at the suction position A4 into the reaction container 19. Dispensing (step S4).

  Here, first, a test sample for analyzing “item A” is dispensed into the reaction container 19 stopped at the sample discharge position Pa. In the next cycle, a test sample for analyzing “item B” in the sample container 11 is dispensed into the reaction container 19 stopped at the sample discharge position Pa. Further, in the next cycle, a test sample for analyzing “item C” in the sample container 11 is dispensed into the reaction container 19 stopped at the sample discharge position Pa.

  Next, when an input for displaying the simple setting screen is performed from the operation unit 80, the simple setting screen is displayed on the display unit 72.

  FIG. 7 is a diagram illustrating an example of a simple setting screen displayed on the display unit 72. The simple setting screen 74 is configured by an “item” column excluding the “position” column from the general setting screen 73 shown in FIG. Further, it is configured by “simple measurement” which is a button for starting analysis under the conditions set in the “item” column. In the “Item” column, “Item A”, “Item B”, “Item C”, “Item D”, etc., which are the same inspection items as the inspection items displayed in the “Item” column of the general setting screen 73 are displayed. Is displayed. In response to an input from the operation unit 80, the input information set in the “item” field is stored in the storage circuit of the system control unit 90 and displayed on the display unit 72. In addition, by inputting simple measurement start designating “simple measurement”, the analysis control unit 50, the data processing unit 60, and the output unit 70 are controlled based on the input information set in the “item” column, and the analysis operation is performed. Will be executed.

  After the simple setting screen 74 is displayed on the display unit 72, when an input for setting an inspection item is performed from the operation unit 80, when dispensing is performed by the sample dispensing probe 21, the system control unit 90. Rejects the input of the inspection item from the operation unit 80, thereby preventing the inspection item from being set on the simple setting screen 74. Further, when the dispensing by the sample dispensing probe 21 is stopped and the mixed solution in each reaction container 19 is being measured by the measurement unit 31, the system control unit 90 inputs the inspection item from the operation unit 80. The inspection item can be set on the simple setting screen 74.

  When dispensing is performed by the sample dispensing probe 21, the setting of the inspection item on the simple setting screen 74 is prevented by rejecting the input for displaying the simple setting screen 74 from the operation unit 80. May be implemented.

  When dispensing by the sample dispensing probe 21 is stopped and the mixed solution in each reaction container 19 is being measured by the measurement unit 31, each column of the simple setting screen 74 is selected by the selection input from the operation unit 80. The set input information is stored in the storage circuit of the system control unit 90 and displayed on the display unit 72. Here, for example, “item A” selected and input in the “item” column is identified and displayed.

  Next, for example, two sample containers 11 accommodating two test samples for analyzing “item A” set on the simple setting screen 74 are held at an arbitrary rack position of an arbitrary sample rack 40. Measurement after the sample rack 40 holding the two sample containers 11 is placed at the standby position A1 on the belt 41 and the sample rack 40 at the retracted position A3, which has been dispensed in step S3, is removed from the belt 41. When a simple measurement start is input from the operation unit 80, the mechanism control unit 52 is based on the inspection item input information set on the simple setting screen 74 supplied from the system control unit 90. To control. The rack detector 44 detects the position of the sample rack 40 at the standby position A1 held by the belt 41 in response to the input of the simple measurement start (step S5 in FIG. 6).

  As described above, when the sample dispensing probe 21 is dispensing, the sample rack 40 having the rack ID set on the general setting screen 73 is prevented by setting the inspection item on the simple setting screen 74. The sample rack 40 remaining in the standby position A1 can be prevented from being detected as the sample rack 40 for analyzing the inspection item set on the simple setting screen 74.

  If the sample rack 40 is not detected by the rack detector 44 in response to the input for starting the simple measurement, the process proceeds to step S8.

  The belt 41 moves all the sample racks 40 whose positions are detected by the rack detector 44 to the drawing position A2. The sample rack 40 moved to the drawing position A2 is moved in the L2 direction by the mechanism unit 51. The container detector 45 detects the sample container 11 held in the sample rack 40. The mechanism control unit 52 detects the rack position of the sample container 11 detected by the container detector 45 based on the detection signal from the container detector 45 (step S6).

  The mechanism 51 moves the sample rack 40 moved to the drawing position A2 to the suction position A4 where the sample in the sample container 11 detected by the container detector 45 can be sucked by the sample dispensing probe 21. When the sample container 11 is not detected from the sample rack 40 moved in the L2 direction by the container detector 45, the process proceeds to step S8.

  The sample dispensing probe 21 dispenses the test samples in all the sample containers 11 detected by the container detector 45 into the reaction container 19 based on the inspection items set on the simple setting screen 74 ( Step S7 in FIG.

  Here, a test sample for analyzing “item A” in the first sample container 11 detected by the container detector 45 held in the sample rack 40 stopped at the suction position A4 is set in the reaction container 19. Dispense into. In the next cycle, a test sample for analyzing “item A” in the second sample container 11 detected by the container detector 45 held by the sample rack 40 stopped at the suction position A4 is a reaction container. Dispense into 19.

  Thus, during the measurement after the dispensing by the sample dispensing probe 21 is stopped, by setting the inspection item on the simple setting screen 74, the standby held by the belt 41 according to the input of the simple measurement start. The sample rack 40 at the position A1 and the sample containers 11 held in the sample rack 40 are detected, and the test samples in all the sample containers 11 held in all the detected sample racks 40 are displayed on the simple setting screen 74. The set inspection item can be dispensed into the reaction container 19 as a sample for analysis.

  Thereby, since the operation which inputs the holding position of the sample container 11 and the test | inspection item of the sample is not required for every test sample, a troublesome operation can be reduced. And even an unfamiliar operator can easily operate. In addition, it can be quickly operated in an emergency.

  In step S7, when the sample rack 40 holding the sample container 11 is placed at the standby position A1 on the belt 41 while dispensing is performed by the sample dispensing probe 21, the standby position A1 is reached. The sample rack 40 and the sample containers 11 held in the sample rack 40 are detected, and the detected samples in all the detected sample containers 11 are used as samples for analyzing the inspection items set on the simple setting screen 74. Dispense into the reaction vessel 19.

  The sample rack 40 holding the sample container 11 that has been dispensed by the sample dispensing probe 21 is moved in the L3 direction, and stops at the drawing position A2 on the belt 41. The belt 41 moves the sample rack 40 stopped at the drawing position A2 to the retreat position A3.

  After the measurement of all the mixed liquids including the test sample dispensed by the sample dispensing probe 21 is completed and the analysis data is output to the output unit 70, the system control unit 90 includes the analysis control unit 50, By instructing the data processing unit 60 and the output unit 70 to end the analysis, the automatic analyzer 100 ends the operation (step S8 in FIG. 6).

  According to the embodiment described above, the rack ID set on the general setting screen 73 is prevented by preventing the setting of the inspection item on the simple setting screen 74 when the sample dispensing probe 21 is dispensing. When the sample rack 40 remains at the standby position A1, the sample rack 40 can be prevented from being detected as the sample rack 40 for analyzing the inspection items set on the simple setting screen 74.

  Further, during the measurement after the dispensing by the sample dispensing probe 21 is stopped, by setting the inspection item on the simple setting screen 74, the standby position A1 held by the belt 41 according to the input of the simple measurement start. The sample racks 40 and the sample containers 11 held in the sample racks 40 are detected, and the test samples in all the sample containers 11 held in all the detected sample racks 40 are set on the simple setting screen 74. It is possible to dispense into the reaction container 19 as a sample for analyzing the inspection items.

  Thereby, since the operation which inputs the holding position of the sample container 11 and the test | inspection item of the sample is not required for every test sample, a troublesome operation can be reduced. And even an unfamiliar operator can easily operate. In addition, it can be quickly operated in an emergency.
