五、新型說明： 【新型所屬之技術領域】 新型領域 本新型涉及用於測定B〇D(生物化學需氧量（或稱為生 物化學耗氧量)）’是示出工廠排水或河流水等的水質的基準 之一；更具體地說’本新型涉及這樣的B〇D自動測定裝置， 該B O D自動測定裝置僅靠設置樣品試料液的原液就能自動 地測定D1值（其為第1天的測定專案）、D5值（其為5天後的測 定專案）、及BOD值。V. New description: [New technology field] New field The present invention relates to the measurement of B〇D (biochemical oxygen demand (or biochemical oxygen demand)) is to show factory drainage or river water, etc. One of the benchmarks for water quality; more specifically, the present invention relates to such a B〇D automatic measuring device, which automatically determines the D1 value by setting the stock solution of the sample sample liquid (which is the first day) The measurement project), the D5 value (which is the measurement project after 5 days), and the BOD value.
C 前 椅;J 新型背景 作為工廠排水或河流水等的水質的基準，有BOD的水 質基準，其測定方法依據JIS-K0102 : 2〇08的標準而定。 該JIS-K0102 : 2〇〇8標準根據以下程序來定製b〇D值的 測定方法：（1)將採自工廠排水或河流水等的試料液(原液) 稀釋到規定濃度；（2)將經稀釋的試料液放置規定的時間， 然後測定溶解而存在於所述試料液中的氧的量，該氧的量 作為D1值（第一個值）；（3)從測定D1值起保存5天，然後測 定溶解而存在於同一試料液中的氧的量，該氧的量作為D5 值(第二個值）；（4)計算出D1值和D5值的差，該差作為b〇D值。 試料液的BOD值大表示D1值和D5值的差大，與第1天 相比，第5天的溶解而存在於所述試料液中的氧的量大幅減 少。即，BOD值越大表示水質惡化得約嚴重。 本文中，D1值是在對試料液採樣的當天測定的；D5值 是在從測定D1值的那天起5天後測定的；D1值和D5值的測 定日如下： D1值的測定日 D5值的測定日 星期一 星期六 星期二 星期曰 星期三 星期一 星期四 星期二 星期五 星期三 由D1值的測定日與D5值的測定日的對應關係可知，儘 管可以僅在星期一到星期五的工作日對D1值進行測定，但 D5值的測定不可避免要在星期六' 星期曰（或節曰）進行。 因此，需要將D5值的測定自動化的方法。如果不使D5值的 測定自動化，為了測定D5值，操作者需要在公休日出勤， 引起成本和管理方面的缺點。 另外’就D1值和D5值的測定而言，手工操作煩雜，誘 發測定錯誤的可能性高。更不用說，難以對容納在多個測 定容器中的試料液測定其BOD值。 在這種情況下，現有技術中已提出自動地測定試料液 的BOD值的各種技術方案(例如，參照專利文獻1、2、3)。 現有技術文獻 專利文獻 專利文獻1曰本特開平6-230013公報 專利文獻2日本實開平6-16864公報C Front chair; J New background As a reference for water quality such as factory drainage or river water, there is a water quality benchmark for BOD, and the measurement method is based on JIS-K0102: 2〇08. The JIS-K0102: 2〇〇8 standard is used to customize the b〇D value according to the following procedure: (1) Dilute the sample liquid (stock solution) collected from factory drainage or river water to a specified concentration; (2) The diluted sample solution is allowed to stand for a predetermined period of time, and then the amount of oxygen dissolved in the sample solution is measured, and the amount of oxygen is taken as the D1 value (first value); (3) is saved from the measured D1 value. 5 days, then measure the amount of oxygen dissolved in the same sample solution, the amount of oxygen as the D5 value (second value); (4) calculate the difference between the D1 value and the D5 value, the difference as b〇 D value. The large BOD value of the sample liquid indicates that the difference between the D1 value and the D5 value is large, and the amount of oxygen present in the sample solution is significantly reduced as compared with the first day. That is, the larger the BOD value, the worse the water quality is deteriorated. Herein, the D1 value is measured on the day of sampling the sample liquid; the D5 value is measured 5 days after the day from which the D1 value is measured; the D1 value and the D5 value are measured as follows: D1 value measurement day D5 value It is known that the D1 value can be measured only on the working day from Monday to Friday, as measured by the correspondence between the measurement date of the D1 value and the measurement date of the D5 value on Wednesday, Tuesday, Tuesday, Wednesday, Wednesday, Monday, Thursday, Tuesday, Friday, Wednesday, Wednesday. However, the measurement of the D5 value is inevitably carried out on Saturday 'week (or thrift). Therefore, there is a need for a method of automating the measurement of the D5 value. If the measurement of the D5 value is not automated, in order to determine the D5 value, the operator needs to be on a public holiday, causing cost and management shortcomings. In addition, in terms of the measurement of the D1 value and the D5 value, manual operation is troublesome, and the possibility of detecting a measurement error is high. Needless to say, it is difficult to measure the BOD value of the sample liquid contained in a plurality of measurement containers. In this case, various technical solutions for automatically measuring the BOD value of the sample liquid have been proposed in the prior art (for example, refer to Patent Documents 1, 2, and 3).

專利文獻3日本特開2004-101495號公報 【新型内容;J 新型概要 新型欲解決之課題 專利文獻1披露了一種樣品的自動測定裝置，其包括供 給樣品瓶的運送裝置、進行打開和閉合樣機構、以 及測定D1值或D5值的機構。 但是，專利文獻1的自動測定裝置具有這樣的機構，該 機構在完成D1值的測定後將樣品瓶保管於專用的收容室 中，將樣品瓶保管5天後取出，採用與測定Dl值的機構同一 個測定機構測定D5值。即，對於同一個測定機構，運送穿 置以每5天的間隔運送同一樣品瓶，同一個測定機構測定第 1天和第5天的溶解而存在於試料液中的氧的量。 因此，專利文獻m自動測定裝置具有這樣的問題：根 據運送裂置容量，能夠測定的樣品瓶數是有限的。此外， 由於通過手卫操作向運送裝置中投人新的樣品瓶，操作者 的失誤會引起這樣一些問題：不是在第5天測定〇5值，等。 特別是，由於採用同一個測定機構測定D1值和〇5值，就di 值和D5值的㈣—者的測定、或者在正相—週中的測定 日的測定而言，均會產生這樣的問題：發生由手工操作或 裝置的誤差而引起的錯.此外，專利文獻[的自動測定裝 置具有這樣的問題：原液的稀釋是手動進行的，經過該稀 釋的樣品瓶是通過手工操作投人到自動測定裝置中的，因 此，操作煩雜，會引起由於手工操作而引起的操作失誤。 M423699 因此’專利文獻1的技術具有這樣的問題：樣品瓶數是 有限的’另外，由於需要部分手工操作，所以會引起由於 手工操作或裝置的誤差而引起的失誤。 專利文獻2具有這樣的機構，該機構自動地移動負栽樣 品容器的托盤並測定第1天測定的D1值和第5天測定的!^值。 但是，與專利文獻丨相同，由於同一個測定部測定Ο】 值彳D5值所以具有這樣的問題：由於托盤的移動機構的 錯°吳或操作者的托盤設置或托盤移動的操作失誤，使得 D5值不是在本來意圖進行測定的一週中的測定日而測定 的。此外，就專利文獻2的技術而言，完成D1值的测定的樣 品容器必須保管在專用的保管場所。由此，引起這樣的問 喊必舄除裝置以外的專用的保管場所。由於向保管場所 的保官或從保管場所中取出樣品容器是以手工操作來進行 的，所以有可能產生操作失誤。如果在保管或取出中產2 操作失誤’則會引起這樣的問題：D5值是在錯誤的測定日 測定的。 專利文獻3披露了這樣的自動分析裝置的技術，該自動 刀析裝置預備了測定D1值的儲料器和測定〇5值的儲料 器，在投入了各個儲料器之後，打開容器並測定D1值或D5 值，然後將完成測定的容器返回到儲料器中 在夕天投人儲料H ’能夠在星期六或星期日進行測定。 但是，與專利文獻1或專利文獻2相同，測定Dl值和D5 值的敎機構共用同—個機構。由此，投人儲料器的操作

D5值測定的Μ㈣ 出全部實現了自動化。 用以欲解決課題之手段 為瞭解決上述問題，本新型的B〇D自動測定裝置包 括：收納庫，該收納庫保管測定過第一值之後的試料液， 直到進行第二值的測定；第一測定裝置，該第—測定裝置 測定所述試料液的第一值；第二測定裝置，該第二測定裝 置在將所述試料液從所述收納庫中取出並測定所述試料液 的所述第二值；其中，所述收納庫具有多個一週中的測定 曰架’所述一週中的測定日架在每個測定所述第_值的一 週中的測定日保管試料液；所述第一測定裴置具有將試料 液按照規定的倍率稀釋的稀釋單元、將通過所述稀釋單元 稀釋了的试料液待機規定的時間以上的待機單元、對通過 所述待機單元待機了的試料液測定其所述第一值的第—測 定單元、將通過所述第一測定單元測定了的試料液注入容 器並將所述容器供給至所述一週中的測定日架的供給單 元；所述第二測定裝置具有從與測定所述第二值的一週中 的測定日相對應的架中取出所述容器的取出單元、從通過 所述取出單元取出的所述容器中對所述試料液進行採樣並 測定所述第二值的第二測定單元。 新型效果 8 M423699 本新型的BOD自動測定裝置㈣僅#設置原液就將稀 釋、第一值的測定、完成了第一值測定的容器的保管、在 正確的一週令的測定日進行的第二值的測定、以及完成了 第二值測定的容器的排出全部實現了自動化。 另外，由於第-測定裝置與第二測定裝置是分別獨立 的機構’所以防止了第一值的測定日與第二值的測定日發 生錯誤的問題。此外，由於能夠分別測定第一值和第二值， 所以能夠同時測定作為第一值的D1和第二值的〇5。 特別是，對於保管完成了第一值測定的試料液的容 器，本新型的收納庫在每個測定第一值的一週中的測定曰 分別進行保管，由於這樣的收納庫成為基準，所以第一測 定裝置和第二測定裝置是獨立運作的。其結果是，與第一 值的測定日相對應的第二值的測定日僅依賴於收納庫進行 的區分，因此，不存在第二測定裝置將其一週中的測定日 弄錯的可能性。收納庫進行的區分僅依賴於第一值的測定 曰，而第一值的測定曰不依賴於除設置原液的操作以外的 手工操作’朗，不存在弄錯第—值的測定日的可能性。 這些、纟。果此夠防止由手工操作失誤引起的錯誤的測定。 此外’對於第二值的測定在星期六、星期日以及節 日進行的If況’不需要手工操作，而自動地測定第二值。 虽然’也不需要將完成了第一值測定的試料液的容器 保管在專用的保管場所。 圖式簡單說明 第1圖疋本新型的實施方案1中的BOD自動測定裝置的 9 M423699 結構圖。 第2圖是本新型的實施方案1中的BOD自動測定裝置的 測定程序的流程圖。 第3圖是實施本新型的實施方案1中的稀釋程序的稀釋

0D自動測定裝置僅靠設置樣品容器 (其容納工廠排水或河流水等試料液）就能自動地實施測定 BOD值所必需的所有的處理、並測定作為結果的BOD值。 由於BOD值為示出工廠排水或河流水的水質的數值，人的 操作穿插在中途程序中，有測定精度降低的可能性。與此 相對，對於實施方案1中的BOD自動測定裝置，由於原液設 定後的所有程序均是自動實施的，所以沒有穿插人的操作 的餘地，能夠以高精度測定BOD值。 第1圖是本新型的實施方案1中的BOD自動測定裝置的 結構圖。第1圖概略地示出BOD自動測定裝置的全部構成， 並示出BOD自動測定裝置所包括的要素的相互關係。第2 圖是本新型的實施方案1中的BOD自動測定裝置的測定程 序的流程圖。第2圖示出BOD自動測定裝置所實施的程序。 BOD自動測定裝置1包括以下要素作為主要要素：收納 庫2，其收納保管容器54，保管容器54是測定過作為第一值 的D1值的容器；D1測定器3，其是測定所述試料液的D1值 的第一測定裝置；以及，D5測定器4，其是測定D5值的第 二測定裝置，D5值是從收納庫2中取出的保管容器54内部的 試料液的第二值。 另外，實施方案1中，D1值定義為第一值的一個例子， D5值定義為第二值的一個例子，但是，對應於與BOD值的 測定相關的規格或次序，由第一值和第二值定義的值是靈 活可變的。 收納庫2將容納測定了 D1值的試料液的保管容器54對 15 M423699 於每個測定了 D1值的一週中的測定日進行區分。由此，收 納庫2包括一週中的測定日架20a〜20e。D1測定器3測定原 液容器50内部的試料液的D1值，並將保管容器54(其容納有 測定完D1值的試料液)供給至與進行測定的一週中的測定 曰相對應的一週中的測定日架20a〜20e〇D5測定器4將與進 行D5值測定的一週中的測定日的5天前的一週中的測定日 相對應的一週中的測定日架的保管容器54從收納庫2所包 括的一週中的測定日架中取出，並測定取出的保管容器内 部的試料液的D5值。D5測定器4還將測定完D5值之後的空 的保管容器54供給至排出架21，排出架21示出測定完成。 D1值是試料液的第一天的溶解而存在於所述試料液中 的氧的量的值，D5值是試料液保存5天後的溶解而存在於試 料液中的氧的量，這兩個值中的任一者均為測定試料液的 BOD值所必需的參數。該由D1值和D5值算出的值為示出試 料液的水質的BOD值。 BOD自動測定裝置1以收納庫2(其收納容納有測定過 D1值的試料液的保管容器54)為基準，從而有可能D1測定器 3和D5測定器4是分別相互獨立地運作的。因此，收納庫2 存在於D1測定器3和D5測定器4之間、並且D1測定器3和D5 測定器4是獨立地運作的，所以收納庫2確實地對保管容器 54進行區分和收納，由此沒有錯誤地實施D1測定器3中的 D1值的測定和與該D1值的測定日相關的測定日中的D5測 定器4中的D5值的測定。 由此，實施方案1中的BOD自動測定裝置1以收納庫2 16 M423699 為基準將D1測定器3和D5測定器4設置在收納庫2的兩邊， 在收納庫2的一端，對容納D1測定器3設置的原液的原液容 器50、和容納已測定了 D1的試料液的保管容器54進行處 理；在收納庫2的另一端，對容納D5測定器4測定的試料液 的保管容器54進行處理，從而可能防止裝置或設備的大型 化、同時不出錯誤地測定BOD值。 在BOD自動測定裝置1中，為了實現以上這樣的功能， D1測定器3和D3測定器4分別包括規定的單元。 D1測定器3包括：原液容器設置單元30，其設置原液容 器50，原液容器50容納作為原液的試料液；稀釋單元31，

Summary of New Types of Problem to be Solved Patent Document 1 discloses an automatic measuring device for a sample, which includes a conveying device for supplying a sample bottle, and an opening and closing mechanism And the mechanism for determining the D1 value or the D5 value. However, the automatic measuring device of Patent Document 1 has a mechanism for storing the sample vial in a dedicated storage chamber after the measurement of the D1 value is completed, and taking the sample vial for 5 days, and taking it out, and adopting a mechanism for measuring the D1 value. The same measuring mechanism measures the D5 value. That is, for the same measuring mechanism, the transporting means transports the same vial every 5 days, and the same measuring means measures the amount of oxygen present in the sample solution dissolved on the first day and the fifth day. Therefore, the automatic document measuring apparatus of the patent document has a problem that the number of vials that can be measured is limited according to the transporting slit capacity. In addition, since a new vial is thrown into the transport device by the hand-held operation, the operator's mistake causes such a problem that the value of 〇5 is not determined on the fifth day, and the like. In particular, since the D1 value and the 〇5 value are measured by the same measuring means, the measurement of the di value and the D5 value (four), or the measurement of the measurement day in the normal phase-week will occur. Problem: A fault caused by a manual operation or an error of the device occurs. In addition, the automatic measuring device of the patent document has a problem that the dilution of the stock solution is performed manually, and the sample vial that is diluted is manually injected into the sample. The automatic measurement device is, therefore, cumbersome to operate, causing operational errors due to manual operations. M423699 Therefore, the technique of Patent Document 1 has a problem that the number of vials is limited. In addition, since partial manual operation is required, errors due to manual operations or errors of the device may be caused. Patent Document 2 has a mechanism for automatically moving a tray of a sample container and measuring the D1 value measured on the first day and the value measured on the fifth day. However, as in the patent document ,, since the same measuring unit measures the value of 彳D5, there is such a problem that D5 is caused by the error of the moving mechanism of the tray or the operation of the operator's tray or the movement of the tray. The value was not measured on the measurement day of the week in which the measurement was originally intended. Further, in the technique of Patent Document 2, the sample container that has been subjected to the measurement of the D1 value must be stored in a dedicated storage place. As a result, such a question is required to remove a dedicated storage location other than the device. Since the sample container to the storage location or the sample container is taken out from the storage place by manual operation, an operation error may occur. If the operation error in the storage or removal of the middle 2 is caused, the D5 value is determined on the wrong measurement date. Patent Document 3 discloses a technique of an automatic analyzer which prepares a stocker for measuring a D1 value and a stocker for measuring a value of 〇5. After the respective stockers are loaded, the container is opened and measured. The D1 value or the D5 value is then returned to the hopper in the container where the measurement is completed. The stock H' can be measured on Saturday or Sunday. However, similarly to Patent Document 1 or Patent Document 2, the 敎 mechanism that measures the D1 value and the D5 value shares the same mechanism. As a result, the error in the operation of the input hopper will cause such a problem: the D5 value is the second in the wrong 6 container secret briber device: she has a problem like this : It is necessary to make a '砀. D5 value 疋 由于 由于 : : : : : : : : : 容器 容器 容器 容器 容器 容器 容器 容器 容器 容器 容器 容器 容器 容器 容器 容器 容器 容器 容器 容器 容器 容器 容器 容器 容器 容器 = 容器 容器 容器It was measured on the wrong measurement day. Further, the technique of Patent Document 3 is to perform the enthalpy of the dilute stock solution by a dynamic dilution wire different from the automatic analyzer, and may correct the error in the sequence or erroneously set the diluted sample liquid to the automatic analyzer. The problem in . Moreover, the automatic measuring device of the prior art has the following: The DD1 value and the job are (4) - a manual operation error or a device error measured by the measuring mechanism causes the Μ value to be wrong, and the problem is completed. The problem that the second container of the m value is to be stored in a dedicated storage place; (3) _ (four) touch the other process phase _; (4) _ test is done: placed in the measurement device, is proceeding At the time of this setting, the operation is lost and § is also the problem of the wrong sample; (5) the measurement, the second: the problem of the automation is not sufficient. Because of these problems, the problem arises: the festival is held on Saturday. The measurement or dilution procedure of 〇5 value, the order of taking out from the storage place, etc. have not been fully automated. The M423699 is in the above problem. 'This new model provides an automatic coffee measuring device, and the automatic measuring device is based on the original liquid. The dilution, the measurement of the di value, the storage of the container in which the D1 value was completed, the measurement of the position performed on the correct measurement day of the week, and the completion of the measurement of the D5 value were all automated. Means for Solving the Problem In order to solve the above problems, the B〇D automatic measuring device of the present invention includes: a storage for storing a sample liquid after the first value has been measured, and measuring the second value; a measuring device for measuring a first value of the sample liquid; and a second measuring device for taking out the sample liquid from the storage and measuring the sample liquid a second value; wherein the storage library has a plurality of measurement trusses in a week; the measurement day rack in the week stores the sample liquid on a measurement day in each week in which the _ value is measured; The first measurement chamber has a dilution unit that dilutes the sample liquid at a predetermined magnification, a standby unit that has been diluted by the dilution unit for a predetermined time or longer, and a sample solution that has passed through the standby unit. a first measurement unit that measures the first value, injects a sample liquid measured by the first measurement unit into a container, and supplies the container to the measurement rack of the week a second measuring device having a take-out unit that takes out the container from a rack corresponding to a measurement day in a week in which the second value is measured, and from the container taken out through the take-out unit The sample liquid is sampled and the second measurement unit of the second value is measured. New effect 8 M423699 The new BOD automatic measuring device (4) only dilutes the first liquid, determines the first value, and completes the first value. The storage of the measured container, the measurement of the second value performed on the measurement day of the correct one week, and the discharge of the container in which the second value measurement was completed are all automated. Further, the first measurement device and the second measurement device It is a separate mechanism'. Therefore, it is prevented that an error occurs in the measurement date of the first value and the measurement date of the second value. Further, since the first value and the second value can be separately measured, the first value can be simultaneously measured. D1 and 第二5 of the second value. In particular, in the container for storing the sample liquid in which the first value measurement is completed, the storage of the present invention is stored in the measurement 一周 for each week in which the first value is measured, and since such a storage is used as a reference, the first The assay device and the second assay device operate independently. As a result, the measurement date of the second value corresponding to the measurement date of the first value depends only on the division by the storage. Therefore, there is no possibility that the second measurement device will mistake the measurement day of the week. The distinction made by the storage is only dependent on the measurement of the first value, and the measurement of the first value does not depend on the manual operation other than the operation of setting the original liquid, and there is no possibility of the measurement date of the wrong value. . These, oh. This is enough to prevent the measurement of errors caused by manual operation errors. Further, the 'condition for the measurement of the second value on Saturday, Sunday, and the day of day' does not require manual operation, and the second value is automatically measured. It is not necessary to store the container of the sample liquid in which the first value measurement has been completed in a dedicated storage place.

Therefore, since the storage 2 is present between the D1 measuring device 3 and the D5 measuring device 4, and the D1 measuring device 3 and the D5 measuring device 4 are operated independently, the storage 2 reliably separates and stores the storage container 54. Thus, the measurement of the D1 value in the D1 measuring device 3 and the measurement of the D5 value in the D5 measuring device 4 in the measurement day related to the measurement date of the D1 value are performed without error. Thus, the BOD automatic measuring device 1 of the first embodiment sets the D1 measuring device 3 and the D5 measuring device 4 on both sides of the storage 2 based on the storage 2 16 M423699, and measures the accommodation D1 at one end of the storage 2 . The stock solution container 50 of the stock solution provided in the unit 3 and the storage container 54 containing the sample liquid in which the D1 has been measured are processed; and the storage container 54 for accommodating the sample liquid measured in the D5 measuring device 4 is processed at the other end of the storage unit 2. Therefore, it is possible to prevent an increase in size of the device or the device without erroneously measuring the BOD value. In the BOD automatic measuring device 1, in order to realize the above functions, the D1 measuring device 3 and the D3 measuring device 4 each include a predetermined unit. The D1 measuring device 3 includes a raw liquid container setting unit 30 that is provided with a raw liquid container 50 that holds a sample liquid as a stock solution, a dilution unit 31 that dilutes the sample liquid in the raw liquid container 50, and a standby unit 32 that will accommodate dilution The standby container 52 of the sample liquid waits for a predetermined period of time or longer; the D1 measurement unit 33 is the first measurement unit that measures the D1 value, and the D1 value is dissolved in the sample solution in the standby container 52 after the standby, and is present in the sample. The amount of oxygen in the liquid; the storage container supply unit 34 which is a storage container 54 for supplying the sample liquid in the storage storage 2; the refill unit 35 which measures the D1 value The liquid is reloaded from the D1 measuring container 53 to the storage container 54; the closing unit 36 closes the opening 54a to the opening of the storage container 54 containing the sample liquid having the measured D1 value, and the supply unit 37 which closes the storage container 54. The measurement trusses 20a to 20e are supplied to one week corresponding to the measurement day of the week in which the D1 value is measured. The storage 2 includes the measurement day frames 20a to 20e in the week corresponding to the measurement day of the week in which the D1 value is measured. As an example, the measurement truss 20a in the week corresponds to Monday, and the measurement day frame 20b in the week. The measurement day frame 20c corresponding to the star on the second half of the week corresponds to Wednesday, and the measurement truss 20d in the week corresponds to Thursday, and the measurement day frame 2〇e in the week corresponds to Friday. Further, the storage 2 further includes a discharge rack 21 that accepts the storage container 54 that is not required for the calculation of the value of b〇d. Further, the D5 measuring device 4 includes a take-out unit 40 that takes out the storage container 54 from the measurement day frames 20a to 20e in the week, and a D5 measurement unit 41 that is a second measurement unit that measures the D5 value, and the D5 value is stored. The amount of oxygen present in the sample solution by the bath solution in the container 54; the B〇D calculation unit 42, which calculates the BOD value based on the D1 value and the D5 value; and the discharge unit 43, which will complete the D5 value. The measured storage container 54 is discharged to the discharge rack 21. Further, the D1 measuring device 3 and the storage 2 are connected so that the storage capacity can be transferred. . Further, the storage 2*D5 measuring device 4 is connected so that the storage unit 54 can be delivered. The supply unit 37 and the take-out unit 4A automatically execute the program based on the storage unit 2. Each of the four units includes a mechanical electrical mechanism necessary for each unit to perform the desired procedure. (Processing procedure of b〇d automatic measuring device) Next, the processing procedure of the b〇d automatic measuring device 1 will be described using Figs. 1 and 2 . Fig. 2 is a flow chart showing all the processes performed by the D1 measuring device 3, the storage 2, and the D5 measuring device 4. In addition, in the step ST1, the stock solution container 5 (the sample liquid (stock solution) in which the factory drain or the river water to be measured is accommodated) is placed on the set table of the raw liquid container and the program 30. Although the stock solution container 50 is set by a person's operation, it can also be automatically set by the lifting device or the transport device M423699. . Next, in step ST2, the dilution unit 31 performs a dilution process in which the sample liquid contained in the raw material container 5 is injected into the dilution container 1 and diluted. The dilution procedure is carried out in such a manner that the sample liquid is reduced in the dilution container 51 by using the dilution water specified by ISKG1() 2: 2008 (hereinafter referred to as "IIS specification,"). The δ-type liquid is diluted to a predetermined dilution ratio. Next, in step ST3, the standby unit 32 waits for a predetermined period of time or more for the standby container 52 (the sample liquid is injected from the dilution chamber 5). In the standby program, the standby unit 32 passes the standby container Μ for a predetermined time or longer as stipulated by the JIS regulation L. If the standby time is insufficient, the D1 value is measured in an insufficiently diluted state, and the result is b〇 The value of d is calculated from the incorrect value. Next, in step ST4, the measurement unit 33 measures the sample liquid that has stood by in the standby container 4 to the D1 measurement container 53 (this will be described later using a map). "Master" and measure the D1 value. This is the D1 measurement program as the first measurement program. The D1 measurement unit 33 measures the D1 value using a known unit or the like based on the specifications defined by the JIS standard. The measured D1 value is taken as Measuring data memory The memory unit or the measured D1 value is printed as the measurement data on the predetermined recording paper. The steps ST1 to ST4 are performed in parallel. In step ST5, the storage container 54 is supplied by the storage container supply unit 34. The figure shows that the processing of step ST5 is performed between #叮4 and step ST6. However, the processing of step ST5 may be performed before the few steps 874. In short, it may be completed before 19 M423699 step ST6. In the storage container 54 (which is used for storage in the storage 2 t), the storage container 54 can be supplied by human resources. Alternatively, the e4 can be cleaned. The transport device or the hoisting device is supplied to the storage unit. The refill unit 35 reassembles the sample liquid containing the measured fine value contained in the D1 measuring container 53 in the storage container supply unit. & 今益54. This is the reloading program. The storage container 54 is placed in the warehouse or the like, and the magazine 8 in which the plurality of storage containers 54 are provided is sent to the measurement day racks 20a to 20e in the week of the storage 2 Followed by In ST7, the closing unit 36 closes the opening of the storage container 54. The wire container 54 accommodates the sample liquid for measuring the fine value. This is the closing procedure. The mechanical arm (not shown) included in the closing unit 36 sets the plug 54a so that The opening σ portion of the vessel 54a of the plug 54a is combined, and the plug is closed by pressing the plug (4) into the opening. By this closing, the storage container 54 (the sample liquid in which the value of the basin is measured) is not subject to the external atmosphere. When the amount of oxygen which is dissolved in the sample liquid after a few days of measurement is measured, the measurement is based only on the inside of the storage container 54 (that is, the sample liquid itself). In the case of storage in the storage 2 In the state of the closed storage container (10), the amount of oxygen dissolved in the secret 0 is changed only by the consumption of the creature or the like of the gorge. 'Next' In the step (4), the supply unit 37 supplies the closed storage container to the scale 2 . This is the supply of wealth. "Library 2 package (4) Correspondence in the week of the m value of the material - the measurement of the day of the day 2 () supply order (3) The storage container 54 is supplied to the next measurement corresponding to the measurement date of ^ 20 M423699 The measuring racks 20a to 20e in the container week are stored. In the ninth step, the storage 2 is stored in the storage unit 37 and stored in the predetermined condition. This is the custody procedure.

The empty dilution container 5 is cleaned. As described above, the dilution unit 31 is added to the sample solution in which the dilution container is the stock solution, and the dilution unit 31 divides the sample liquid into two stages of 8 times and 8 = ^. dilution. As shown in the third paragraph, the dilution material is a failure caused by the material of the person. (Fourth, the details of the standby program are explained. The machine program is the standby capacity that will accommodate the diluted sample solution. (4) The program above the standby time, which is executed by the standby unit 32. The claw gauge 25 is defined by 34: the diluted sample liquid is reserved for a predetermined time or longer 'and then the D1 value is measured. This is because 'if diluted When the dilution state of the subsequent sample liquid is insufficient, a variation occurs when the D1 value indicating the amount of oxygen dissolved in the sample liquid is measured. The standby unit 32 includes a transport device. The transport device will accommodate the diluted cesium. The standby container 52 of the liquid material moves to the side of the D1 measuring unit 33. The standby unit 32 waits for a predetermined time or longer by the moving time, and the standby container 52 stands by. The predetermined time defined by the current jIS standard is 15 minutes (the standby time in the soil standby private sequence is 15 minutes or longer). For this reason, the movement time of the transport device that moves the standby container 52 to the D1 measurement program for the standby program is 15 minutes. As described above, the standby unit 32 can wait for the standby container 52 to wait for 15 minutes or more from the dilution program to the D1 measurement program. The predetermined time of 15 minutes or longer is only an example prescribed by the JIS standard, and the standby unit 32 is used. The program may wait for a different period of time depending on the specifications of the standby container 52. In particular, when the specification of the measurement of the BOD value, which is based on the JIS standard, is changed in the future, the predetermined time may be a time other than 15 minutes. After the standby program is completed, the diluted sample liquid is sent to the D1 measurement program for measuring the D1 value. Further, since the dilution process is performed in three stages, the standby container 52 containing the sample liquid includes a plurality of standby containers 52a and 52b. 52c. The standby program waits for a predetermined period of time or longer in the standby containers 52a, 52b, and 52c, wherein the standby containers 52a, 52b, and 52c respectively accommodate the sample liquid diluted at the different dilution rates. 26 11 Measurement Procedure) Next, to D1 The details of the measurement procedure are described. In the measurement program, the paste unit 33 measures the m value, and the D1 value is dissolved in the standby sample solution and the oxygen present in the sample solution is shown in Fig. 5 to illustrate the 01 measurement in the embodiment i of the present invention. An illustration of the program. Figure 5 shows the dilution program and the D1 measurement program in combination. The description of the dilution procedure is as described above' and is omitted here. The D1 measuring unit 33 injects the diluted sample liquid extracted from the standby container 52 into the m measuring container 53. The DU receiving unit 33 measures the amount of oxygen dissolved in the sample solution by various measuring methods of known techniques to measure the D1 value. In addition, as a known technique of the measurement method, there are, for example, a measuring device including a detector of an electric or optical type, for measuring the amount of oxygen dissolved in the sample solution. The D1 measuring unit 33 measures the value of 〇1 of each measurement container, and each of the measurement containers accommodates each of the sample liquids diluted in three stages. Further, since there are many types of sample liquids depending on the place or time at which the stock solution is sampled, the m measurement order is used to measure the D1 value of each type. Therefore, in the embodiment of the present invention, the standby unit 32 moves the standby container 52 to the D1 measuring unit 33, and the D1 value is measured. The standby container 52 has three standby containers 52a arranged in parallel according to the type of the sample liquid. 52b, 52c. This scheme is as shown in Figure 6. Fig. 6 is a schematic view showing the arrangement of the containers in the standby program in the embodiment i of the present invention. In the standby program 32, eight standby containers are arranged in parallel (the _ a in the figure 6 is opposite to each other and a plurality of standby containers corresponding to the type of the sample liquid are arranged side by side in the moving direction. 'The temple machine 52a accommodates Dilute to 2 times the sample solution, dilute to 4 times the standby container 52b liquid-containing material solution, and the standby barnifier 52c to accommodate the sample material solution diluted to 8 times: ==Drainage test sample with different liquid sample test , ============================================================================================================= Diluted to 4 times the sample solution and diluted to: The program, the standby container of the column flows into the D1 measurement guide in the following direction, and the D1 value of the sample is recorded as the measurement data. In the predetermined record 2 =: = as the measurement data, the printer can confirm the measured D1 value and save the data as a tree. Operation (supply program) Next, the supply program and the like will be described. The tube material is _____ , its ^=5=== : order 34 is set and delivered The reloading unit % refills the measurement liquid from the measurement container 53 into the delivery storage container 54. The material 28 M423699 closes the refilled storage container 54 through the closing unit 36. By closing, the sample in the storage container 54 is closed. The liquid is stored in the storage 2 and is not affected by the outside. The supply program supplies the storage container 54 to the storage 2 using the supply unit 37. Here, the storage 2 includes the measurement day corresponding to one week of the measurement D1 value. The measurement day frame 2〇a~2〇e in one week. The measurement day of the day is determined by the measurement day of the day when the day frame 2〇a corresponds to the D1 value is Monday, and the measurement truss 20b of the week corresponds to the D1 value. The measurement in the week is the case on Tuesday, and the measurement of the day frame 20c in one week corresponds to the measurement in the week of 1) 1 value. The measurement is performed on Wednesday, and the measurement of the truss 2〇d in one week corresponds to the week of the D1 value. The measurement day in the middle is the case of Thursday, and the measurement truss 2〇e in one week corresponds to the case where the measurement day in one week of the Di value is Friday. Further, since the current situation is that 'normally Saturday and Sunday are public holidays, the storage 2 shown in Fig. 1 does not include the measurement truss in the week corresponding to Saturday and Sunday. Of course, the storage 2 may further include a measuring day of the week corresponding to Saturday and Sunday. Further, the storage 2 further includes a discharge rack 21'. The discharge rack 21 discharges the storage 谷益54 which has measured the D5 value (i.e., calculated the BOD value). As shown in Fig. 7, the crucible 1 measuring device 3 is moved in a direction orthogonal to the conveying direction of the storage 2 (or the supply unit 37 is moved), and the storage container 54 is supplied to the measurement in the week of the measurement D1 value. The corresponding truss in the week of the day. Fig. 7 is a schematic view showing the relationship between the measuring truss in the week and the D1 measuring device and the D5 measuring device in the first embodiment of the present invention. The supply unit 37 supplies the storage container 54 accommodated in the magazine 80 to the measurement day frame in the week corresponding to the measurement day of the week in which the value of the value of 29 M423699 D1 is measured. At this time, the D1 measuring device 3 or the supply unit 37 moves in the transport direction of the storage 2, and the supply unit 37 supplies the storage container 54 accommodated in the storage tank 80 to the measurement D1 value of the measurement day frames 20a to 20e in the week. The measurement of the week 曰 corresponds to the measurement of the day of the week. For example, when the measurement day in one week of the D1 value of the D1 value is measured as Monday, as shown in Fig. 7, the supply unit 37 supplies the storage container 54 to the measurement day frame 20a of the week. In addition, the supply unit 37 may supply the storage container 54 as it is to the measurement day frames 20a to 20e of the week, or may be supplied to the measurement day frame 20a of the week in a state of being housed in the magazine 80 as shown in FIG. 20e. Further, when the measurement day in one week in which the D1 value of the D1 value is measured is Wednesday, the supply unit 37 supplies the storage container 54 to the measurement truss 20c in one week. As a result, the supply unit 37 divides the storage container 54 containing the sample liquid having the measured D1 value into the measurement day of each week and moves it to the vertical direction or the horizontal direction with respect to the storage 2 . The measurement truss in one week corresponding to the measurement 曰 in one week of the measurement of the D1 value. The storage 2 can divide the measurement day of one week for each D1 value, thereby storing the sample container 30. (Storage Program) Next, the storage program will be described. The storage container 2 stores the storage container 54 in a constant environment for a predetermined time in the measurement day frames 20a to 20e in one week corresponding to the measurement day in the week in which the D1 value is measured. The diluted stock solution is incubated for the specified period of time. The other 30 M423699 outer 'for a predetermined time' is described in accordance with the five days specified in the JIS standard, but may be appropriately changed. (Removal Procedure) Next, the extraction procedure will be described. Each of the measurement day frames 2〇a to 2〇e in each of the storages 2 has a transport device function. The storage container 54 supplied from the D1 measuring device 3 is sequentially moved from the end on the D1 measuring device 3 side to the D5 measurement. 4 side. By this movement, the storage container 54 containing the sample liquid for which the D1 value has been measured is gradually brought close to the measuring device 4, and the D5 measuring device 4 can easily take out the storage container 54. In the take-out procedure, the take-out unit 40 takes out the storage container from the measuring rack of the week. Here, the measurement day in one week of the D5 value is the measurement day of the week after 5 days of the measurement date of the D1 value. For example, when the measurement 曰 in the week of the D1 value is Monday, it is necessary. The D5 value of the sample liquid contained in the storage container 54 was measured on Friday. For this purpose, the take-out unit 40 measures the storage container 54 from one of the measurement days in the week before the measurement date of one week of the measurement D5 value in the measurement day frames 20a to 20e in the week. Take out the rack. When the measurement 曰 in the week of the D5 value is Friday, the take-out unit 4 取出 takes out the storage container 54 from the measurement day frame 2〇a which is the week corresponding to Monday, which is five days ago. This is shown in Fig. 7'. The 〇5 measuring device 4 (the take-out unit 40) is movable in the direction orthogonal to the transport direction of the storage 2, similarly to the D1 measuring device 3. By moving in the direction orthogonal to the conveyance direction of the storage 2, the take-out unit 40 moves to the position of the measurement day of the required one week, and takes out the storage container 54 from the measurement day of the day of 31 M423699. At this time, since the take-out unit 40 takes out the storage container 54 from the measurement day frame 20a in the week corresponding to Monday, which is five days ago, there is no such concern: in the calculation of the BOD value, the D1 value is in the middle of the week. The measured enthalpy is confused with the day of the measurement of the corresponding D5 value. (D5 Measurement Program) Next, the D5 measurement program will be described. In the D5 measurement program, the D5 measuring unit 41 measures the D5 value which is the amount of oxygen which is dissolved in the sample solution in the storage container 54 taken out by the take-out unit 40 and which is present in the sample liquid. Fig. 8 is a view showing the D5 measurement procedure in the first embodiment of the present invention. Fig. 8 shows a state in which the tube container 54 taken out by the take-out unit 40 moves to the inside of the D5 measurement container, and the D5 measurement unit 41 measures the D5 value of the sample liquid. The sample liquid in each of the storage containers 54 taken out by the take-out unit 40 is sent to the D5 measurement container 55 of the D5 measuring unit 41 in this order. Fig. 8 shows a state in which the container 55 is sent from the storage container to the D5 measuring container 55 of the D5 measuring unit 41. Further, the D5 measuring device 4 includes a opening mechanism that opens the plug 54a of the storage container 54. By the opening mechanism, the D5 measuring device 4 can open the plug 54a of the storage container 54 and take out the sample liquid contained therein. Here, the D5 measuring unit 41 measures the D5 value by measuring the amount of oxygen dissolved in the sample liquid, which is the same as the measurement method of the known technique used in the D1 measuring unit. Further, when the D5 measurement unit 41 completes the measurement of the D5 32 M423699 value, the sample liquid is discarded into the discharge tank 411. As a result, the D5 measurement container 55 becomes empty. Further, the 'D5 measuring unit 41 measures the sample liquid of the storage container 54 taken out by the take-out unit 40, and the storage container 54 is a week corresponding to the measurement 曰 five days before the measurement of the D5 value. In the measuring truss taken out of the measuring unit 40, the edge is moved in the direction perpendicular to the storage 2, and the storage container is automatically taken out from the measurement rack of the necessary week for this purpose even on Saturday or Sunday. On the public holiday, the D5 Chuanqi 4 removes the storage container 54 already prepared in the storage 2 from the measurement day of the corresponding week. Therefore, the measurement of the value does not fail, that is, the author only passes the The raw material container of the 4 nanoliter stock solution is set in the D1 measurement H3 on the working day from Monday to Friday, and thereafter, all the materials of the 彳疋 program are automatically performed. As a result, the D1 value and the D5 value of the sample liquid were measured based on the combination of the measurement days in the positive week. - The reading order needs to be in the day of the week from Monday to Friday, and the BOD automatic measuring device 1 needs to measure the coffee value in all of these weeks. In this case, after the automatic measurement is performed as the sample solution of the stock solution, the D1 value is automatically measured. The automatic measurement device 1 automatically supplies the storage container 54 to the week of the D1 value. Measure any of the truss pools ~20e in the week corresponding to 曰. Since the D5 tester 4 automatically takes out the storage container 54 from the measurement day in the week corresponding to the measurement 曰 five weeks before the measurement, the measurement is performed in the week. Measurement 33 M423699 Even on Saturday or Sunday, the D5 value can be determined by the D5 measurement program without problems. As described above, it is understood that 'the D1 measuring device 3 and 1' are based on the storage bin 2 (which includes the measuring day frames 20a to 20e in one week of the measurement day in which the D1 value of each D1 value can be determined). Since the measuring devices 4 operate independently of each other, the BOD value can be measured regardless of whether it is a public holiday such as Saturday or Sunday. Thereby, the B〇d value of the sample liquid was accurately measured. Further, since the storage 2 accurately performs the storage of the container and the measurement of the D1 value to the D5 value, the BOD automatic measuring device can simultaneously achieve operational efficiency and efficiency of the operation area. When the D5 value is measured, the D5 measuring unit 41 records the D5 value as measurement data in a predetermined memory unit or as measurement data on a predetermined recording sheet. Further, the D5 measuring unit 41 calculates the D5 value and the D1 value, and the calculated value is used as the BOD value. This BOD value shows the water quality of the sample liquid. The 〇5 measuring unit 41 stores the BOD value in a predetermined memory unit or prints on a predetermined recording sheet, similarly to the value of D5. That is, the D5 measuring unit 41 further includes a B〇D calculating unit 42, and the BOD calculating unit 42 calculates the BOD value. (Discharge Program) The discharge unit 43 discharges the storage accommodating member 54 from which the sample liquid has been discharged to the discharge rack 21 in the discharge program. The discharge rack 21 is installed in the storage 2, and temporarily stores the empty storage container 54 in which the measurement of the BOD value becomes unnecessary. The discharge rack 2i automatically sends the storage container 54 by the transport device and transfers it to the cleaning process 34 M423699. At this time, the storage container 54 can be sent to the cleaning unit that performs the cleaning process by the transport device, or the operator can transport the storage container 54 to the cleaning unit by human operation. Here, regardless of whether or not the sample liquid remains in the storage container 54, the storage container 54 is cleaned, so that the storage container 54 can be reused in subsequent measurement. Further, Fig. 8 shows a state in which the empty storage container 54 is discharged to the discharge rack 21. The discharge rack 21 is provided in the vicinity of one of the measurement trusses 20e corresponding to Friday, but may be provided in the vicinity of the measurement truss 20a in the week corresponding to Monday, and may be separately set in the measurement rack of the week. 2〇a and the vicinity of each rack of the measuring day frame 20e. Like the measurement day frames 2a to 20e of the week, the discharge rack 21 also includes a transport mechanism that transports the received empty caviar 54 (or the bin 8 accommodating therein) in a predetermined direction. By this conveyance, the operator can loop back the empty storage container 54 to be discharged to the washing program and the like. (Opening Mechanism) The D5 measuring device 4 includes a opening mechanism that opens the plug 54a of the storage container 54. The plugging mechanism uses the principle of leverage to open the plug. #, The opening mechanism includes an arm that presses the fulcrum of the arm with respect to the connecting portion of the retaining container 54 and the plug 54a, combines and expands the arm and the fulcrum, and the opening mechanism opens the plug. Of course, the opening mechanism can also include the component of the arm material to open the plug. The plug can also be opened by a structure other than the lever. The plug 54a of the storage container 54 can be surely and easily opened by such a plugging mechanism 'D5 measuring device 4'. 35 M423699 As described above, the BOD automatic measuring device 1 of the first embodiment can automatically measure the BOD value of the sample liquid by merely providing the raw liquid container 50 containing the sample liquid as the stock solution, without causing a measurement error in one week. The phenomenon. (Embodiment 2) Next, Embodiment 2 will be described. In the second embodiment, the function of processing the measured D1 value, D5, and BOD value in the BOD automatic measuring device 1 described in the first embodiment as measurement data will be described. Fig. 9 is a view showing the configuration of a BOD automatic measuring device in the second embodiment of the present invention. Fig. 9 shows the b〇d automatic measuring device 1 simplified and shown. In addition to the elements of the storage 2, the D1 measuring device 3, and the D5 measuring device 4, the BOD automatic measuring device 1 according to the second embodiment further includes a control unit 1 'the control unit 100 controls the D1 measuring device 3 and the storage 2 and At least one portion of the detector 4. The control unit 100 controls at least one of the programs including the BOD automatic measuring device 1 described in the first embodiment. Further, the control unit 1 creates and updates a measurement data table corresponding to the D measurement container 5 3 or the D 5 measurement container 5 5 that accommodates the sample liquid as the measurement target of the BOD value. The stock solution container 50 is distinguished by the place or time at which the sample liquid is sampled. The BOD value must be determined by distinguishing the container by the location or time of the sample solution being sampled. When the BOD value is measured by falsifying the properties of the sample liquid, the water quality of the factory drainage or river water for sampling the sample liquid is not obtained. For this reason, the control unit 100 must measure the value of b〇d after the sample liquid of a specific container in each program is identified at a certain point or time of 36 M423699. This is because in the BOD automatic measuring device, the D1 value, the D5 value, and the B〇D value of the sample liquid sampled at a certain place or time are measured in the schedule of the shortest five days, respectively. If the control unit_ cannot identify a certain stock solution container 5, the values of the measured m value, D5 value, and enthalpy value corresponding to the sample liquid phase are unknown. In addition, in the first drawing, the stock solution container 5 is used until the D1 value is measured. However, in this case, the sample liquid after the D1 value measurement is stored in the storage container 54. Make a difference. The control unit 100 manages the measurement data table. The measured data is shown in Figure 1. Fig. 10 is a pattern diagram of the measurement data table in the second embodiment of the present invention. The first map shows the measurement data table 101 after the measurement of the D1 value, the measurement data table 102 after the measurement of the D5 value, and the measurement data table 103 after the calculation of the D5 value in the order from top to bottom. The unit 1 updates the measurement data table every time the measurement in each program is completed. The measurement data sheets 101 to 103 have identification information 110, a D1 value 111, a D5 value 112, and a BOD value 113 for identifying a container accommodating a specific sample. In the embodiment of the present invention, the identification information of the original liquid container 50 is input to the control unit 100', and the identification information identifying the storage container 54 is delivered to the storage container 54 by, for example, stamping or printing. The identification information is obtained by at least one of an ID code, a barcode, a two-dimensional barcode, and an identification identifier. The control unit 100 includes a mechanism for reading these codes or the like (located on a setting table or the like of the storage container supply unit 34 in which the storage container 54 is installed), and the identification information 11 of the storage container 54 is identified by the mechanism. By this identification, the control unit 丨00 37 M423699 writes the identification information into the identification information u〇_ of the measurement data table. In the _ towel, the material - _ sub, in the 敎 _ table (8) ~ ι 〇 3 diluted to 峨 (four) of the loss when the remuneration program is completed, the control unit _ will be identified by the identification information 2" in the _ container 53 The sample solution in the middle (which is obtained by diluting the stock solution Gumi 5G) is written in the measurement data table. The measurement data table is updated to the measurement data table 101 by writing the D1 value. In the 10th figure, the measurement material is measured. In Table 101, the value "3 〇 is written as the D1 value. When the D5 measurement program is completed, the control unit immediately writes the D5 value of the sample liquid removed from the (1) container 53 and stored in the storage container μ, which is identified by the identification (4) "A-1", into the measurement data table. 1〇1. The measurement data table 1〇1 is updated to the measurement data table 1〇2 by writing the 05 value. In the measurement data table 102 in the first graph, the value "1.5" is written as the D5 value. Further, when the calculation program is completed, the control unit 1 writes the BOD value of the storage container 54 identified by the identification information "A-1 '' into the measurement data table 丨〇 2 ^ by writing the BOD value, the measurement data is Table 1〇2 is updated to the measurement data table 1〇3. In Fig. 10, 'In the measurement data table 1〇3, the value “〇·75” is written as the BOD value. The value “〇75, for use by JIS The formula specified by the specification is the value calculated from the value and the D1 value. Finally, the control unit Zou 1〇〇 updates the measurement chart, and outputs the measurement data table 103 in which the BOD value is written as the final result. Further, the control unit 100 stores the measurement data table in the storage unit 105. &' preferably, each time the measurement data sheet is updated, the measurement data table memory 38 71 M423699 is displayed on the 昼 昼 surface in the memory section 105.
