The reaction container 2 for accommodating a photometric object is disposed between the multi-wavelength photometer 12 and the light source 13. Reference numeral 14 denotes a cleaning mechanism.

Next, a control system and a signal processing system of the automatic analyzer will be described. 15 is a microcomputer, 16
Is an interface, 17 is a log (log) converter, 1
8 is an A / D converter, 19 is a reagent dispensing mechanism, 20 is a washing pump, and 21 is a reagent dispensing mechanism. Reference numeral 22 denotes a printer for printing, 23 denotes a CRT as display means, 24
Is a hard disk as storage means, and 25 is an operation panel (keyboard) as input means.

[0004] The sample placed in the sample cup 6 is analyzed by an operator (stored in a memory in the microcomputer 15) in accordance with an input from the operation panel 25.
, A predetermined amount is dispensed into the reaction vessel 2 by the nozzle 8 of the sample pipetting mechanism 7. The reaction container 2 into which the sample has been dispensed is transferred to the reagent dispensing position by rotating the reaction disk 1. Thereafter, in accordance with an input from the operation panel 25, a predetermined amount of the reagent is dispensed into the reaction container 2 into which the sample has been dispensed by the nozzles of the reagent pipetting mechanisms 10A and 10B. Subsequently, the sample and the reagent are stirred by the stirring mechanism 11 and mixed.

When the reaction vessel 2 crosses the photometry position, the absorbance is measured by the multi-wavelength photometer 12. The measured absorbance is taken into the microcomputer 15 via the Log converter 17, the A / D converter 18, and the interface 16. This absorbance is measured by microcomputer 1
5, the data is converted into density data. The conversion into the concentration data is performed based on a calibration curve created in advance from the absorbance of the standard sample solution measured by the analysis method for each item. The measured component concentration data is stored in the printer 22.
And to the CRT 23.

A user (nurse, doctor, laboratory technician, maintenance service or maintenance worker) displays a display screen (CRT) 23 for setting various parameters necessary for measurement, registering a sample, confirming an analysis result, and the like. Perform in. This display screen uses a menu format, and is divided into a plurality of screens for each function, for example, as shown in FIG. These screens are displayed by a user who analyzes a sample using the analyzer (a laboratory technician, a nurse, a doctor, etc.), a user who maintains the analyzer, and a user who performs maintenance service of the analyzer. Etc. are operated by many users in different fields.

FIG. 12 is a view showing an analyzer screen 260 which is an example of a display screen, as described above. In FIG. 12, a menu name 230a "routine menu",
230b "QC menu",... Are displayed, and below them, respective menus 240a, 240b,.
Are displayed, and further below, function key numbers 250a, 250 corresponding to the respective menus are displayed.
.. are displayed. Using this analyzer screen 260, the user operates the screen display.

That is, in step 400 shown in FIG. 11, when an operator operates a function key, an original menu, that is,
The analyzer screen 260 is displayed. And Step 4
At 02, a screen number is selected. For example, if the operator is a nurse, when the menu name is screen number 07-01 (not shown in FIG. 12) of the emergency specimen registration, an emergency specimen registration screen is displayed in step 403. Then, an inspection is performed based on the displayed screen contents, and in step 404, when one inspection is completed, in step 405, it is determined whether or not to transition to another screen. When transitioning to another screen, the process returns to step 401 and the analyzer screen 260 is displayed again. Then, in step 402, for example, the screen number 06 of the menu name operation monitor
When −01 is selected, steps 403 to 40
4 is executed. Similarly, a number of screen numbers are selected and the processing is executed. Then, in step 405, if there is no need to transition to another screen, the process ends. Thus, the operator executes the operation of the automatic analyzer while checking the display screen.

[0009]

However, in the above-described conventional automatic analyzer, when the user operates the automatic analyzer, the analyzer screen is displayed on the display screen.
Many menus unnecessary for the user are displayed. For this reason, the selection of the required screen number is complicated, and not only the operation efficiency is low, but also the possibility that an operation error occurs is high. For example, nurses do not usually use parameter setting screens or environment setting screens such as analysis conditions, because routine analysis of samples is a normal task. Routine operation screens are mainly used for sample analysis. Use a monitor screen to display the results and device status.

For this reason, for example, when the nurse operates the automatic analyzer, after selecting the screen number 07-01 of the menu name of the emergency sample registration in the analyzer screen 260 and executing the processing, From the analyzer screen 260, the screen number 06 of the operation monitor with another menu name
01 must be selected. Therefore, as described above, the selection of a necessary screen number is complicated.

Therefore, it is conceivable to apply the menu switching processing method described in JP-A-63-314665 to an automatic analyzer. JP-A-63-31
According to the menu switching processing method described in Japanese Patent No. 4665, a system menu and a user menu are provided, and only the system menu is operated, only the user menu is operated, and both the system menu and the user menu are used. Operations can be performed. However, in the menu switching method described in the above-mentioned publication, the contents of both the system menu and the user menu are fixed, and a large number of users, especially nurses handling automatic analyzers, are provided to many users. However, operability cannot be improved.

Further, it is conceivable to apply the menu processing method described in JP-A-2-224007 to an automatic analyzer. According to the menu processing method described in Japanese Patent Application Laid-Open No. 2-224007, menu items are automatically arranged at the end of processing in descending order of use frequency. However, in the above menu processing method, menu items are automatically arranged in descending order of use frequency. Therefore, in an automatic analyzer, a nurse or the like wants to arrange menu items according to operability regardless of use frequency. In case, I can not respond.

An object of the present invention is to realize an automatic analyzer with improved operability, in which a screen corresponding to the range of use of a user can be newly registered from a plurality of screens as a menu screen. is there.
