FIG. 1 is an overall schematic configuration diagram of an automatic analyzer to which an embodiment of the present invention is applied.

In FIG. 1, a large number of sample containers 1 containing a sample are arranged on a sample transport disk 2. The suction / exhaust nozzle of the sample dispensing mechanism 5 is connected to the sample syringe pump 7. The operations of the pump 7 and the dispensing mechanism 5 are controlled by a microcomputer (calculation control unit) 3 that controls the operation of each mechanism unit and calculates measurement data via the interface 4. A large number of reaction vessels 6 are arranged on the reaction table 17 rotatably provided with respect to the reaction bath 9, forming a reaction line. A constant temperature liquid maintained at 37 degrees Celsius is supplied from the constant temperature liquid supply unit 10 to the reaction bath 9.

The multi-wavelength photometer includes a light source 14 and a multi-wavelength spectroscope 15, and the reaction table 17 is rotationally transferred so that the row of reaction vessels 6 crosses the light beam from the light source 14. The used reaction vessel 6 is washed by the washing mechanism 19 and used for reuse. The stirring mechanism 13 mixes the sample added to the reaction vessel 6 with the reagent solution corresponding to the analysis item. The measurement signal based on the reaction solution obtained by the multi-wavelength spectroscope 15 is converted from an analog signal to a digital signal by the A / D converter 16 and input to the microcomputer 3.

On the reagent disk 26A for the first reagent and the reagent disk 26B for the second reagent, various reagent bottles 12 corresponding to each analysis item are installed along the circumference. That is, the reagent discs 26A and 26B are reagent bottle storage portions that can be selectively rotated. A barcode reading device 23A is arranged in the vicinity of the disk 26A, and a bar code reading device 23B is arranged in the vicinity of the disk 26B. The reagent dispenser includes reagent dispensers 8A and 8B and a reagent syringe pump 11. These pipettes 8A and 8B suck and hold a predetermined amount of the reagent solution in the reagent bottle 12 stopped at the suction position in the suction / discharge nozzles, rotate the suction / discharge nozzles on the reaction vessel row, and stop at the reagent receiving position. The retained reagent solution is discharged into the reaction vessel 6 which is being used. The reagent solution dispensed at this time is of the type corresponding to the analysis item assigned to each reaction vessel.

Specimen transport disk 2, reaction vessel 6, pump 7, reagent dispensing pipetta 8A, 8B, reagent syringe pump 11, dispensing mechanism 5, reaction bath 9, constant temperature liquid supply unit 10, stirring mechanism 13, light source 14, reaction table A sample analysis unit is formed by 17, a cleaning mechanism 19, bar code readers 23A and 23B, reagent disks 26A and 26B, a multi-wavelength spectroscope 15, a microcomputer 3, and the like.

Each reagent bottle 12 has a reagent barcode label with a barcode printed on its outer wall. The information displayed as this barcode indicates, for example, a reagent bottle code unique to each bottle consisting of a sequence number, the size of the bottle, the expiration date of the reagent solution, and whether the reagent is the first reagent, the second reagent, or the third reagent. The reagent dispensing order, the maximum number of times that the reagent solution can be analyzed, the reagent dispensing amount indicating the amount used for one dispensing, the production lot number, and the like.

The reagent information read from each reagent bottle 12 by the barcode readers 23A and 23B is stored in the storage unit (memory) 25 or the corresponding memory area of the microcomputer 3. As the reagent bottle 12 is stored in the reagent disks 26A and 26B, the reagent information is read by the bar code readers 23A and 23B. At that time, the rotation angle detection provided on the reagent disks 26A and 26B is detected. A signal indicating the setting position of each reagent bottle is output by the unit and input to the microcomputer 3 via the interface 4. Reagent information, bottle set position and analysis items are stored in association with each other.

The operator can input various information using the screen of the CRT (display unit) 18 and the keyboard 21. The measurement results of the analysis items can be displayed on the printer 27 and the CRT 18. The information on the optical recording medium (optical disc) 24 is read by the reading device and stored in the storage unit 25 or the corresponding memory area of the microcomputer 3. The information stored in the optical recording medium 24 is, for example, as follows. That is, the analysis item code displayed in 5 digits, the parameters commonly used in the analysis items, the parameters stored separately for each reagent bottle, and the like. Among them, the parameters commonly used in the analysis items are the wavelength used in the photometer, the sample amount, the calibration method, the standard liquid concentration, the standard liquid number, the check limit value of the analysis abnormality, and the like. The parameters for each reagent bottle include the reagent type, reagent dispensing order, reagent bottle code, reagent solution volume, reagent dispensing amount, maximum number of analyses, and reagent manufacturing date.

In the storage unit 25, in addition to the information read from the optical recording medium 24, the operating conditions of each mechanical unit of the automatic analyzer, the analysis parameters of each analysis item, the determination logic for managing the bottle of each reagent, and the reagent bottle. The maximum number of analyzes that can be performed and the analysis results read from are stored. Reagent information is provided by an optical recording medium provided by the manufacturer upon delivery of the reagent bottle. If the reagent information is not prepared by the optical recording medium, the operator shall input the information written on the visual confirmation sheet attached to the reagent bottle into the automatic analyzer using the screen of the CRT 18 and the keyboard 21. You can also.

A sample barcode label having a barcode printed on the outer wall of the sample container 1 is attached to the sample container 1. The information displayed as this barcode is, for example, a sample identification number that uniquely determines a sample. This number is read by the barcode reading device 28, and the correspondence between the sample position and the sample identification number is recognized by the angle detection of the sample transport disk 2. On the other hand, since the analysis items corresponding to the sample identification numbers are input and stored in advance by the keyboard 21 and the CRT 18, the sample position, the sample identification number, and the analysis items are associated and stored when the previous barcode is read. In addition, it is generally possible to identify whether the sample is a standard sample, a control sample, or a general sample by the upper number of the sample identification number.

The analysis of the entire automatic analyzer is performed in the order of data processing such as sampling, reagent dispensing, stirring, photometry, reaction vessel cleaning, and concentration conversion as follows. A plurality of sample containers 1 containing samples are installed on the sample disk 2. The sample disk 2 is controlled by the computer 3 via the interface 4. Further, in the sample disk 2, the bar code on the outer wall of the sample container 1 is read by the bar code reading device 28, and the sample and the analysis item are associated with each other. After that, it rotates and moves under the probe of the sample dispensing mechanism 5 according to the order of the samples to be analyzed, and the sample of the predetermined sample container 1 is moved to the reaction container by the operation of the sample pump 7 connected to the sample dispensing mechanism 5. A predetermined amount is dispensed into 6. The reaction vessel 6 into which the sample is dispensed moves in the reaction vessel 9 to the position where the first reagent is added. A predetermined amount of the reagent sucked from the reagent container 12 is added to the moved reaction vessel 6 by the operation of the reagent pump 11 connected to the suction / exhaust nozzle of the reagent dispensing pipetter 8. The reaction vessel 6 after the addition of the first reagent moves to the position of the stirring mechanism 13, and the first stirring is performed. When the reagent disks 26A and 26B are set up to the fourth reagent, addition-stirring of such a reagent is performed for the first to fourth reagents.

The reaction vessel 6 in which the contents are agitated passes through the luminous flux emitted from the light source 14, and the absorbance at this time is detected by the multi-wavelength spectroscope 15. The detected absorbance signal enters the computer 3 via the interface 4 via the A / D converter 16 and is converted into the concentration of the sample. The density-converted data is printed out from the printer 27 via the interface 4 and displayed on the screen of the CRT 18. The reaction vessel 6 for which photometry has been completed moves to the position of the cleaning mechanism 19, is discharged from the inside by the vessel cleaning pump, is cleaned with a cleaning liquid, and is provided for the next analysis.

In the automatic analyzer configured as described above, the maintenance screen is displayed on the CRT (display unit) 18. The CRT 18 may be a display device such as a liquid crystal.

FIG. 2 is a diagram showing an example of the maintenance screen 1801 displayed on the CRT 18. On the screen 1801, the maintenance item name 201, the remaining valid period (%) 202 for each maintenance item, the next scheduled implementation date and time 203, the remaining deadline 204, and the required time 205 are displayed in a list for each maintenance recommended implementation cycle. Present information to the person to help schedule maintenance.

The above maintenance items and recommended implementation cycles are predetermined and set in the database described later.

On the maintenance screen 1801 shown in FIG. 2, information on maintenance items classified for each cycle is displayed. In the example of FIG. 2, it is classified and displayed as Day (day), Week (week), Month (month), and Somemes (as needed).

These maintenance items are classified according to the maintenance recommended execution cycle registered in the database described later (for example, if the recommended execution cycle is 24 hours, it is displayed on the Day). Maintenance items for which the recommended implementation cycle is not registered in the database (items whose next maintenance time does not depend on the measurement cycle, etc.) are displayed in Somemes.

If the next scheduled implementation date and time specified by the user (operator) is shorter than the recommended implementation cycle, the next scheduled implementation date and time specified by the user is displayed in the "next implementation scheduled date and time" 203 column.

Depending on the usage pattern of the automatic analyzer, it may be displayed in a cycle such as every two weeks or every two months.

On the maintenance screen 1801 shown in FIG. 2, the remaining validity period (%) 202 is displayed as a percentage for each maintenance item. The remaining validity period (%) is the change from the last maintenance implementation date and time to the maintenance screen display with respect to the factors (elapsed time, number of analyzes, operating time, etc.) that affect the maintenance implementation time. The proportion of the amount. For example, when a recommended maintenance execution cycle is set for a certain maintenance item, the maintenance execution time of this maintenance item is affected by the elapsed time from the last maintenance implementation date and time. In this case, the remaining effective period (%) is the ratio of the remaining time to the recommended maintenance execution cycle.

Depending on the maintenance item, multiple remaining validity periods (%) may be set. For example, in the replacement of the comparison electrode, which is one of the maintenance items, the elapsed time and the number of analyzes affect the maintenance implementation time. At this time, several methods for displaying the remaining validity period (%) are assumed. Assumed display methods are (1) to display all remaining valid periods (%) related to maintenance items, (2) to display the one with the highest (low) remaining valid period (%), and (3) always 1 The remaining validity period (%) for one element is displayed, and the remaining validity period (%) for the remaining elements is displayed in a pop-up or another screen. It is important to select an appropriate display method in consideration of the usage pattern. In one embodiment of the present invention, the computer 3 calculates the item having the lowest remaining effective period (%), which is determined from the remaining time and the number of analyzes for the corresponding maintenance item, and the memory. It is assumed that the data is stored in the database of 25 and displayed on the display unit 18.

The remaining validity period (%) on the maintenance screen 1801 of FIG. 2 is indicated by a number and a bar. If the remaining time for each maintenance item is simply displayed, the length of the bar may grow endlessly and may not fit on the screen. By simply displaying the remaining effective period (%), which is a ratio, not the remaining time on the screen 1801, it is possible to display each maintenance item in an area of the same size.

As described above, since the remaining maintenance deadline for each maintenance item is displayed, it is possible to visually understand the maintenance priority (urgency), and the required time is also displayed for each maintenance item. Therefore, based on the information, the user can use it to formulate a maintenance schedule according to the operation schedule of the automatic analyzer. In addition, depending on the maintenance item, the display can assist in determining the ordering time and the number of consumables.

Further, on the maintenance screen 1801 of FIG. 2, the display can be changed according to the value of the remaining valid period (%) for each maintenance item. For example, the bar display of the remaining effective period (%) displayed in the maintenance items "reaction cell replacement", "reaction tank cleaning", and "ISE dilution tank cleaning" displayed in the Month column of FIG. 2 remains. The display (color) of each bar changes depending on the value of the validity period (%). By checking the color of the bar, the operator can intuitively understand the priority or urgency of maintenance. The value of the remaining validity period (%) at which the display changes can be set for each maintenance item, and it is more desirable if it can be changed by the operator.

Further, on the maintenance screen 1801 of FIG. 2, the next scheduled implementation date and time 203 of the maintenance can be displayed for each maintenance item. The next scheduled date and time 203 will be updated when the maintenance is performed.

Further, on the maintenance screen 1801 of FIG. 2, the remaining maintenance period 204 can be displayed for each maintenance item. The display unit of the remaining period 204 may be appropriately changed such as days, hours, and the number of analyzes.

Further, on the maintenance screen 1801 of FIG. 2, the required maintenance time 205 stored in the DB (database) can be displayed for each maintenance item. The required time 205 may be predetermined for each maintenance, or may be updated by calculating from the actual time taken. In addition, whether or not to display the required time is arbitrary, and it is not necessary to display it because it may be a complicated display in a usage mode in which the operator is familiar with maintenance.

By confirming the maintenance screen 1801 of FIG. 2, the operator can confirm various information regarding the maintenance items for each cycle at a glance. It is considered that this will lead to an appropriate decision on the maintenance schedule or a reduction in the time required for the decision.

FIG. 3 is a diagram showing a maintenance screen 1802 which is an extension of the maintenance screen 1801 of FIG. 2, and in addition to the maintenance item information display area C classified for each cycle, the maintenance item display area A to be performed during the day. , Has a display area B for maintenance items that are recommended to be implemented in the near future. The maintenance screen 1802 can be displayed in place of the maintenance screen 1801, and it is possible to arbitrarily select which one to display.

It is not essential to prepare the display area A and the display area B of the maintenance screen 1802, but by estimating and presenting the maintenance items to be performed on the day or in the near future based on the remaining deadline or its ratio, It will be possible to support the formulation of maintenance schedules.

Hereinafter, the display area A and the display area B will be described.

First, the display area A will be described.

In the display area A, maintenance items to be performed during the day are displayed in a list. FIG. 6 is an algorithm for selecting maintenance items to be displayed in the display area A. The algorithm shown in FIG. 6 is implemented for all maintenance items set in the automatic analyzer. FIG. 5 is a diagram showing a DB 300 for managing information for each maintenance item, and the DB 300 is stored in the memory 25. This DB 300 has each maintenance name 301, recommended execution cycle 302, last implementation date and time 303, remaining deadline rate threshold value a304, user-specified implementation date and time 305, remaining deadline rate threshold value b306, required time 307, Today flag 308, Recognition (implemented in the near future). Recommended) Consists of flag 309. Flags 308 and 309 are used when the user registers temporary Today 308 and Recognition 309. In addition, the flags 308 and 309 can be enabled (True) for the clicked maintenance item by pressing the "Add to Today" and "Add to Recognition" buttons displayed on the screen 1802 described later. it can. Flag 308 has a higher priority than flag 309. Further, when the maintenance item is executed after the flags 308 and 309 are set to True, the flag is set to False.

The algorithm of FIG. 6 is started when the display instruction of the maintenance screen 1802 of FIG. 3 is received. When this algorithm is started, the current date and time is first acquired (step S101).

Next, the recommended implementation cycle 302 and the final implementation date and time 303 of the maintenance item are acquired from the DB 300 (step S102). The elapsed time of the maintenance item is calculated from the current date and time acquired in step S101 and the last implementation date and time acquired in step S102 based on the following equation (1) (step S103).

Elapsed time = current date and time-last implementation date and time ... (1)
Next, the remaining time of the maintenance item is calculated from the elapsed time of the above equation (1) and the recommended execution cycle 302 of the maintenance item based on the following equation (2) (step S104).

Remaining time = Recommended implementation cycle-Elapsed time ... (2)
Whether or not the maintenance item should be displayed in the display area A (whether or not the remaining time is 24 hours or less) is determined based on the remaining time of the above formula (2) (step S105). If the remaining time is 24 hours or less, the maintenance item is displayed in the display area A (step S112), and the process ends.

In step S105, if the remaining time is greater than 24 hours, the Today flag 308 is acquired (step S106), and it is determined whether or not the Today flag 308 is True (step S107). If the Today flag 308 is True, that is, it is determined from the remaining time whether or not it is a maintenance item that should be performed during the day, and the corresponding maintenance item is displayed in the display area A (Today formed in the display unit). Display in the column (column of the day)) (step S112), and end the process.

In step S107, if the Today flag 308 is not True, it is determined whether or not the user-designated execution date and time has been set in the DB 308 (step S108). If the user-specified execution date and time has not been set, the process ends.

If the user-specified execution date and time has already been set in step S108, the "user-specified execution date and time" set in the DB 300 is acquired (step S109), the user-specified remaining time is calculated (step S110), and the user-specified remaining time is calculated. It is determined whether or not is 24 hours or less (step S111).

In step S111, if the user-specified remaining time is 24 hours or less, the maintenance item is displayed in the display area A (step S112), and the process ends.

In step S111, if the remaining time specified by the user is not 24 hours or less, the process ends.

The user-specified remaining time is calculated by the following equation (3).

Remaining time specified by user = Date and time specified by user-Current date and time ... (3)
Next, the display area B will be described.

FIG. 7 is an algorithm for selecting maintenance items to be displayed in the display area B.

When this algorithm is started, the current date and time is first acquired (step S201).

Next, the recommended implementation cycle 302 and the final implementation date and time 303 of the maintenance item are acquired from the DB 300 (step S202).

The elapsed time of the maintenance item is calculated from the current date and time acquired in step S201 and the last implementation date and time acquired in step S202 based on the above formula (1) (step S203).

Next, the remaining time of the maintenance item is calculated from the elapsed time of the above formula (1) and the recommended execution cycle 302 of the maintenance item based on the above formula (2) (step S204).

Next, the Recognition flag set in the DB 300 is acquired (step S205), and it is determined whether or not the acquired Recognition flag is True (step S206). If the acquired Recognition flag is True, the maintenance item is displayed in the display area B (step S210), and the process ends.

In step S206, if the acquired Recognition flag is not True (False), the remaining expiration rate is calculated by the following equation (4) (step S207).

Remaining deadline rate = Remaining time / Recommended implementation cycle ・ ・ ・ (4)
Next, the remaining period rate threshold value a set in the DB 300 is acquired (step S208), and it is determined whether or not the remaining period rate calculated in step S207 is equal to or greater than the remaining period rate threshold value a (step S209). If the remaining period rate is equal to or greater than the remaining period rate threshold value a, the process ends. If the remaining period rate is less than the remaining period rate threshold value a, the maintenance item is displayed in the display area B (step S210), and the process ends.

Next, the display area C will be described. The display area C is an area for displaying maintenance items for Week, Month, and Someties, and is basically the same as the display contents shown in FIG. FIG. 4 is an additional explanatory view of the display of FIG.

In FIG. 4, when a maintenance item is clicked in the display area C, a button for transitioning to a maintenance execution screen, a maintenance detail screen, and a schedule setting screen is displayed as a menu for the clicked maintenance item. The example shown in FIG. 4 is an example when the maintenance item is reaction cell replacement. In addition, a button for adding the specified maintenance item to Today or Recommendation (recommended column to be implemented in the near future) is displayed.

When you press the maintenance execution button, the screen for executing the specified maintenance item is displayed.

When the maintenance details are pressed, a screen for displaying the details of the specified maintenance items (status, related maintenance items, maintenance modules to be implemented, related consumables information) is displayed.

FIG. 8 is a diagram showing a maintenance detail screen 1803. In FIG. 8, the target maintenance item clicked on the screen 1802 shown in FIG. 4 and its state are displayed.

In addition, in the display of related maintenance items, maintenance items related to the target maintenance items are displayed. For example, if the target maintenance item is "reaction cell replacement", the maintenance items that need to be continuously performed, "reaction system cleaning", and "cell blank measurement" are displayed as essential related maintenance items. Although implementation is not essential, maintenance items for the same module, such as "cleaning the reactor filter," are displayed as optional related maintenance items.

In addition, the related consumables information displays information on consumables such as detergents and replacement parts related to the target maintenance. At that time, necessary consumables information may be displayed only for the target maintenance items, or consumables may be displayed when essential related maintenance items are included. Further, the operator may be allowed to select those display contents.

In addition, the maintenance target module visually displays the module in which the target maintenance item is implemented. In the example of FIG. 8, the “analysis unit” is the maintenance module to be implemented in the target maintenance item “reaction cell replacement”.

This maintenance detail screen 1803 can be referred to as auxiliary information at the time of schedule setting, which will be described later. Further, the maintenance detail screen 1803 can be displayed as a sub screen on the maintenance screen 1802 shown in FIGS. 3 and 4.

FIG. 9 is a diagram displayed on the maintenance screen 1802 with the maintenance detail screen as the sub screen 1804. The sub screen 1804 can be moved and its size can be changed by dragging.

Next, a case where the schedule setting button shown in FIG. 4 is pressed will be described.

FIG. 10 is a diagram showing a schedule setting screen 1805 that is displayed when the schedule setting button is pressed. In FIG. 10, as the target maintenance item, the name of the maintenance item to be changed in the schedule setting is displayed. This target maintenance item is the maintenance item clicked to display the schedule setting button.

To specify the next execution date and time, select whether or not to set the next scheduled execution date and time. For the next execution date and time, enter the next scheduled execution date and time. If [No] is selected in the above "Specify next implementation date and time", it is desirable to deactivate the display. Maintenance recommended settings are settings related to maintenance recommendations. Select the conditions under which the recommendation is made, such as the elapsed time from maintenance, operating time, number of measurements, and remaining amount. Set the remaining expiration date to be displayed in red and yellow in the bar display. In the cycle column, set the maintenance cycle (basically, it is not changed, and conditions that are looser than the initial value specified by the manufacturer cannot be added).

In the bar display, the Red value corresponds to the threshold value a stored in the DB 300. The Red part turns the bar display red and is a key for displaying maintenance items in Recognition. Yellow corresponds to the threshold value b stored in the DB 300. This is the key to making the bar color yellow. The Red and Yellow values can be set according to the period value or the remaining expiration date (%).

FIG. 11 is a diagram showing a schedule setting screen 1805 when the next implementation date and time is not specified. As shown in FIG. 11, when the next implementation date and time is not specified, the next implementation date and time column becomes inactive. This is an example of a setting screen when maintenance is recommended outside the cycle time.

FIG. 12 is a diagram showing the above-mentioned schedule setting algorithm.

In FIG. 12, the maintenance item for which the next scheduled implementation date and time or the maintenance recommended setting is to be changed is selected (step S301). Next, the schedule setting button is pressed (step S302) to display the schedule setting screen (step S303). Then, it is determined whether or not to specify the next scheduled implementation date and time (step S304), and when the next scheduled implementation date and time is specified, [Yes] is selected in the next implementation date and time specification (step S305), and the next implementation date and time is set. Input (step S306).

Next, it is determined whether or not to change the maintenance recommended setting (step S307). Even if the next scheduled implementation date and time is not specified in step S304, the process proceeds to step S307. If the maintenance recommended setting is changed in step S307, the process proceeds to step 308 to change the maintenance recommended setting. Then, it is determined whether or not to reflect the setting (step S309). Even if the recommended maintenance setting is not changed in step S307, the process proceeds to step S309. In step S309, when the setting is reflected, the enter button is pressed (step S310), and when the setting is not reflected, the cancel button is pressed (step S311).

The clock generation unit 29 shown in FIG. 13 serves as a clock, and the remaining time calculation unit 31 acquires the current time from the clock generation unit 29. Further, the remaining time calculation unit 31 acquires data from the DB 300 stored in the memory 25, and executes steps S101 to S104, S109, and S110 of FIG. 6 and steps S201 to S204 and S207 of FIG.

Further, the maintenance required time extraction unit 34 extracts the required time of the DB 300 stored in the memory 25 and displays it on the display unit 18 via the determination unit 345. Further, based on the input from the schedule change unit 32 and the input unit (keyboard) 21, the algorithm of FIG. 12 is executed together with the determination unit 35.

Further, the maintenance recommended setting change unit 33 executes the algorithm of FIG. 7 together with the remaining time calculation unit 31 and the determination unit 35. The determination unit 35 controls the display content of the display unit 18 based on the information from the remaining time calculation unit 31, the maintenance required time extraction unit 34, the schedule change unit 32, and the maintenance recommended setting change unit 33.

As described above, according to one embodiment of the present invention, by confirming the screen 1801 shown in FIG. 2 or the screen 1802 shown in FIG. 3, maintenance items to be carried out on the same day and maintenance items to be carried out in the near future can be carried out. Information on recommended maintenance items, required time of maintenance items, and maintenance items classified by cycle can be confirmed at a glance. This makes it possible for the operator to easily grasp the maintenance items to be performed on the day in consideration of the analysis operation and to acquire the information for determining the maintenance schedule after the day.

Further, according to an embodiment of the present invention, even when the maintenance schedule is changed, the display can be easily changed in response to the change.

It is desirable that the related information for each maintenance item can be presented in the screens 1801 and 1802 or on another screen. Related information includes information on parts to be used (model number, inventory quantity, price, last order date and time), consumables information (model number, inventory quantity, price, last order date and time), and maintenance items recommended to be performed at the same time. (Maintenance of the same module, adjustment work when replacing parts, etc.). This information is often taken into consideration in maintenance scheduling, and it is thought that making it possible to refer to it all at once will support scheduling.

In the above-described embodiment, the remaining effective period (%) is displayed by a bar, but the remaining effective period (%) may be displayed by a meter, a graph, a mark, or a color. In this specification, bars, meters, graphs, marks, and colors are collectively defined as graphic display.
