  A plurality of reaction vessels 24a are arranged on the outer periphery of the reaction tank 24 along the circumferential direction, and the reaction vessel 24a is rotated by a drive device (not shown) so that the reaction vessel 24a is dispensed by the sample probe 25 ( The position where the sample is discharged) and the dispensing position (the position where the reagent is discharged) by the first and second reagent probes 26, 27. Moreover, the reaction tank 24 has the function of a thermostat which keeps the reaction liquid accommodated in the reaction vessel 24a at a constant temperature. The reaction tank 24 has a pump 31 that circulates a constant temperature liquid maintained at a constant temperature (for example, about 37 ° C.), and the reaction container 24 a is immersed in the constant temperature liquid circulated in the reaction tank 24. By doing so, the temperature of the reaction solution accommodated in the reaction vessel 24a is adjusted to be a constant temperature (for example, about 37 ° C.). In addition, although the component which suppresses propagation of miscellaneous bacteria is added to the constant temperature liquid, this antibacterial effect will fall with time. Therefore, it is recommended that the constant temperature liquid in the reaction tank 24 be exchanged daily (reaction tank water exchange) in order to suppress the growth of germs.

Here, the power management setting is a setting of a sleep mode (a function of turning off a part of power when not in use at night or the like for the purpose of power saving) or a power supply of an automatic analyzer (first and second power supplies 32 and 33). This is a setting related to the ON / OFF schedule. The initial preparation setting is information relating to the initial preparation of the automatic analyzer, and includes an execution date of initial preparation, a scheduled start time for preparation, a scheduled end time for preparation, preparation items, and the like. In addition, initial preparation includes initial preparation (referred to as automatic initial preparation) automatically performed by an automatic analyzer such as warm-up of each part, photometer confirmation, reaction vessel cleaning, reaction tank water exchange, etc. There are initial preparations (hereinafter referred to as manual initial preparations) manually performed by an operator such as reagent replenishment, calibration, and accuracy control. In addition, when the initial preparation setting items are not set, appropriate initial values are registered.

  The calculation unit 13 performs a calculation based on information stored in the storage unit 14 in accordance with an instruction from the control unit 12, and sends the calculation result to the storage unit 14 and the display device 15.

  Next, the details of the time calculation process related to the scheduled start time of the automatic initial preparation will be described with reference to the flowchart of FIG.

  The control unit 12 of the control device 11 determines whether the scheduled end time of automatic initial preparation is input to the scheduled preparation end time display unit 202 of the setting screen 200 or a registration button is pressed on the setting screen 300 by an input unit (not shown). Then, the calculation unit 13 is instructed to start the time calculation process.

  First, the calculation unit 13 confirms the preparation execution item stored as the initial preparation setting in the storage unit 14 (step S101).

  Next, the required time corresponding to each preparation item of the preparation execution item is read from the required time data 400 stored in the storage unit 14 (step S102).

  Next, the time required to finish all the preparation execution items of the initial preparation setting in the storage unit 14 is calculated, and the calculation is performed backward from the preparation completion scheduled time set and displayed in the preparation completion scheduled time display unit 203. Thus, the scheduled preparation start time is calculated and stored in the storage unit 14 as the initial preparation setting (step S103).

  Then, the scheduled preparation start time of the initial preparation setting is displayed on the planned preparation start time display unit 202, and the process is terminated (step S104).

The operation of the present embodiment configured as described above will be described.
In the automatic analyzer, the control unit 12 uses a power management setting stored in the storage unit 14 to reduce standby power when the analysis process is not performed for several hours or more, such as at night or on holidays. Control is performed so that the unit power supply (first power supply 32) is in a stopped state (sleep mode). However, even in the sleep mode, the power source (second power source 33) of the operation unit 10, the first and second reagent disks 22 and 23 (the function of the reagent cold storage for keeping the reagents stored in the reagent containers 22a and 23a) is stopped. do not do.

(Automatic initial preparation setting)
The operator sets automatic initial preparation on the automatic initial preparation setting screen 200 displayed on the display device 15 of the operation unit 10.

Therefore, the items related to automatic initial preparation can be selected as a selection formula to shorten the setting time, the timer can be set to the scheduled power-on time, and the waiting time for the operator during automatic initial preparation can be shortened, improving the efficiency of the entire initial preparation. I am trying. However, since the end time of the automatic initial preparation changes according to the selected setting item of the automatic initial preparation, the end time cannot be accurately grasped and set. In particular, when an operator who is unfamiliar with the device sets the items for automatic initial preparation, it is difficult to grasp the time at which automatic initial preparation ends, and automatic initial preparation does not end at the desired time, As a result, there is a concern that the efficiency of the entire analysis work may be reduced.

  On the other hand, in the present embodiment, since it is configured to calculate the preparation start scheduled time for automatically starting the automatic initial preparation based on the scheduled preparation end time and the preparation item, the operator can The scheduled end time can be ascertained, and a decrease in efficiency of the entire analysis work can be suppressed.
