Abstract

The present invention provides a weighing system and electronic balance used therein that are capable of inhibiting data falsification. The weight of an object of measurement measured using a mass measurement unit 21 is associated with measurement information including conditions or state at the time of measurement and is stored by a measurement result storage unit 30. An image data generation unit 22 generates image data on the basis of the weight of the object of measurement and the associated measurement information stored in the measurement result storage unit 30. A display control unit 23 displays the image data generated by the image data generation unit 22 on a display unit 50. A history information storage unit 40 stores the image data from one or more measurements displayed on the display unit 50 as history information. Storing image data as history information in this way makes it easier to inhibit data falsification than when text data is stored.

Description

計量システム及びこれに用いられる電子天秤Weighing system and electronic balance used therefor
　本発明は、電子天秤を用いて測定対象物の質量を測定するための計量システム及びこれに用いられる電子天秤に関するものである。 The present invention relates to a weighing system for measuring the mass of an object to be measured using an electronic balance, and an electronic balance used therefor.
　電子天秤には、測定対象物が載置される秤量皿と、秤量皿に載置されている測定対象物の荷重を検出する荷重検出部とが備えられている。荷重検出部により検出される荷重に基づいて測定対象物の質量が測定され、その測定結果が表示部に表示される。このような電子天秤をはじめとする分析装置の中には、測定結果を履歴情報として分析装置内の記憶部に記憶させたり、外部のサーバに記憶させたりすることができるものもある（例えば、下記特許文献１参照）。 The electronic balance is provided with a weighing pan on which the measurement object is placed and a load detection unit that detects the load of the measurement object placed on the weighing dish. The mass of the measurement object is measured based on the load detected by the load detection unit, and the measurement result is displayed on the display unit. Some analyzers including such an electronic balance can store measurement results as history information in a storage unit in the analyzer, or can be stored in an external server (for example, See Patent Document 1 below).
　図４は、従来の計量システムの構成例を示したブロック図である。この計量システムには、例えば電子天秤１００と、当該電子天秤１００に接続されたプリンタ２００とが備えられている。電子天秤１００は、荷重検出部１１０、制御部１２０、測定結果記憶部１３０、履歴情報記憶部１４０及び表示部１５０などを備えている。 FIG. 4 is a block diagram showing a configuration example of a conventional weighing system. The weighing system includes, for example, an electronic balance 100 and a printer 200 connected to the electronic balance 100. The electronic balance 100 includes a load detection unit 110, a control unit 120, a measurement result storage unit 130, a history information storage unit 140, a display unit 150, and the like.
　制御部１２０は、例えばＣＰＵ（Central Processing Unit）を含む構成であり、ＣＰＵがプログラムを実行することにより、質量測定部１２１、画像データ生成部１２２、表示制御部１２３、テキストデータ生成部１２４及びプリント出力部１２５などとして機能する。測定時には、荷重検出部１１０により検出される測定対象物の荷重に基づいて、質量測定部１２１により測定対象物の質量が測定され、その値が計量値として測定結果記憶部１３０に記憶される。 The control unit 120 includes, for example, a CPU (Central Processing Unit), and when the CPU executes a program, the mass measurement unit 121, the image data generation unit 122, the display control unit 123, the text data generation unit 124, and the print It functions as the output unit 125 and the like. At the time of measurement, based on the load of the measurement object detected by the load detection unit 110, the mass of the measurement object is measured by the mass measurement unit 121, and the value is stored in the measurement result storage unit 130 as a measured value.
　このとき、測定結果記憶部１３０には、測定時の条件又は状態の情報などの測定情報が、計量値に対応付けて記憶される。画像データ生成部１２２は、測定結果記憶部１３０に記憶されている情報に基づいて、画像表示用の画像データを生成する。そして、画像データ生成部１２２により生成された画像データを用いて、表示制御部１２３が表示部１５０に測定結果を表示させる。 At this time, the measurement result storage unit 130 stores measurement information such as information on conditions or states at the time of measurement in association with measurement values. The image data generation unit 122 generates image data for image display based on the information stored in the measurement result storage unit 130. Then, the display control unit 123 causes the display unit 150 to display the measurement result using the image data generated by the image data generation unit 122.
　この例では、上記のように測定結果を表示部１５０に表示させることができるだけでなく、プリンタ２００で印刷することもできるようになっている。テキストデータ生成部１２４は、測定結果記憶部１３０に記憶されている情報に基づいて、印刷用のテキストデータを生成する。このテキストデータがプリント出力部１２５からプリンタ２００に出力されることにより、測定結果が印刷される。 In this example, not only the measurement result can be displayed on the display unit 150 as described above, but also the printer 200 can print it. The text data generation unit 124 generates text data for printing based on the information stored in the measurement result storage unit 130. The text data is output from the print output unit 125 to the printer 200, whereby the measurement result is printed.
　図５は、測定結果の印刷態様の一例を示した図である。この例では、計量値２０１の他、電子天秤の機種情報２０２、シリアルナンバー２０３及びソフトウェアのバージョン情報２０４といった測定時の条件や、測定の日付２０５、測定の時刻２０６、ユーザの識別情報２０７及び管理番号２０８といった測定時の状態などが、測定結果として記録紙に印刷されている。 FIG. 5 is a diagram showing an example of a printing mode of measurement results. In this example, in addition to the measurement value 201, measurement conditions such as model information 202 of the electronic balance, serial number 203, and software version information 204, measurement date 205, measurement time 206, user identification information 207, and management The state at the time of measurement such as number 208 is printed on the recording paper as the measurement result.
　図４に示すように、テキストデータ生成部１２４により生成されたテキストデータは、プリント出力部１２５によりプリンタ２００に出力することができるだけでなく、履歴情報記憶部１４０にも記憶される。これにより、複数回分の測定時における測定結果及び対応する測定情報が、履歴情報としてテキストデータで保存される。 As shown in FIG. 4, the text data generated by the text data generation unit 124 can be output to the printer 200 by the print output unit 125 and also stored in the history information storage unit 140. Thereby, the measurement result and the corresponding measurement information at the time of the measurement for a plurality of times are stored as history information as text data.

　上記のように、履歴情報記憶部１４０に履歴情報を保存しておけば、その後に履歴情報を読み出して印刷したり、証拠として利用したりすることが可能になる。しかしながら、従来はテキストデータを履歴情報として保存していたため、データの改竄が容易に行われてしまう可能性があった。 As described above, if history information is stored in the history information storage unit 140, the history information can be subsequently read out and printed, or used as evidence. However, conventionally, since text data is stored as history information, the data may be easily tampered with.
　また、従来の構成では、テキストデータ以外のデータを履歴情報として保存しておくことができない。そのため、例えばグラフ表示のような画像を保存しておくことはできず、履歴情報として保存可能な情報が少ないという問題もあった。 In the conventional configuration, data other than text data cannot be saved as history information. Therefore, for example, an image such as a graph display cannot be stored, and there is a problem that there is little information that can be stored as history information.
　本発明は、上記実情に鑑みてなされたものであり、データの改竄を抑制することができる計量システム及びこれに用いられる電子天秤を提供することを目的とする。また、本発明は、より多くの情報を履歴情報として保存することができる計量システム及びこれに用いられる電子天秤を提供することを目的とする。 The present invention has been made in view of the above circumstances, and an object thereof is to provide a weighing system capable of suppressing falsification of data and an electronic balance used in the weighing system. Another object of the present invention is to provide a weighing system capable of storing more information as history information and an electronic balance used therefor.
　本発明に係る計量システムは、電子天秤を用いて測定対象物の質量を測定し、その測定結果を表示部に表示させるための計量システムであって、荷重検出部と、質量測定部と、測定結果記憶部と、画像データ生成部と、表示制御部と、履歴情報記憶部とを備える。前記荷重検出部は、測定対象物の荷重を検出する。前記質量測定部は、前記荷重検出部により検出される荷重に基づいて測定対象物の質量を測定する。前記測定結果記憶部は、前記質量測定部により測定される測定対象物の質量を、測定時の条件又は状態の情報を含む測定情報に対応付けて記憶する。前記画像データ生成部は、前記測定結果記憶部に記憶されている測定対象物の質量及び対応する測定情報に基づいて、画像データを生成する。前記表示制御部は、前記画像データ生成部により生成された画像データを前記表示部に表示させる。前記履歴情報記憶部は、前記表示部に表示される１回又は複数回分の測定時における前記画像データを履歴情報として記憶する。 A weighing system according to the present invention is a weighing system for measuring the mass of an object to be measured using an electronic balance and displaying the measurement result on a display unit, which includes a load detection unit, a mass measurement unit, and a measurement unit. A result storage unit, an image data generation unit, a display control unit, and a history information storage unit are provided. The load detection unit detects a load of the measurement object. The mass measurement unit measures the mass of the measurement object based on the load detected by the load detection unit. The measurement result storage unit stores the mass of the measurement object measured by the mass measurement unit in association with measurement information including information on conditions or states at the time of measurement. The image data generation unit generates image data based on the mass of the measurement object and the corresponding measurement information stored in the measurement result storage unit. The display control unit causes the display unit to display the image data generated by the image data generation unit. The history information storage unit stores the image data at the time of one or more measurements displayed on the display unit as history information.
　このような構成によれば、各測定時に表示部に表示される画像データが、履歴情報として履歴情報記憶部に記憶される。このように、履歴情報として画像データを記憶することにより、テキストデータを記憶する場合よりもデータの改竄を抑制することができる。 According to such a configuration, the image data displayed on the display unit during each measurement is stored in the history information storage unit as history information. Thus, by storing image data as history information, data tampering can be suppressed more than when text data is stored.
　また、履歴情報として記憶される画像データには、測定結果である測定対象物の質量だけでなく、測定時の条件又は状態などの測定情報が含まれている。テキストデータでは記憶できないような測定情報も、画像データであれば記憶できる場合があるため、より多くの情報を履歴情報として保存することができる。 Further, the image data stored as the history information includes not only the mass of the measurement object that is the measurement result, but also measurement information such as conditions or states at the time of measurement. Measurement information that cannot be stored with text data may be stored with image data, so that more information can be stored as history information.
　前記画像データには、測定の日付、測定の時刻、グラフ表示及びユーザの識別情報の少なくとも１つが含まれていてもよい。 The image data may include at least one of a measurement date, a measurement time, a graph display, and user identification information.
　このような構成によれば、測定の日付、測定の時刻、グラフ表示及びユーザの識別情報の少なくとも１つを含む画像データが、履歴情報として履歴情報記憶部に記憶される。これらの情報は、特に改竄を防止する必要性が高い測定情報であるため、画像データで記憶することにより効果的に改竄を抑制することができる。また、グラフ表示は、テキストデータでは記憶できない測定情報であるが、画像データであれば記憶することができる。 According to such a configuration, image data including at least one of measurement date, measurement time, graph display, and user identification information is stored as history information in the history information storage unit. Since these pieces of information are measurement information that is highly necessary to prevent tampering, it is possible to effectively suppress tampering by storing them as image data. The graph display is measurement information that cannot be stored in text data, but can be stored in the case of image data.

　図１は、本発明の一実施形態に係る計量システムの構成例を示したブロック図である。本実施形態に係る計量システムには、例えば電子天秤１と、当該電子天秤１に接続されたプリンタ２とが備えられている。電子天秤１は、荷重検出部１０、制御部２０、測定結果記憶部３０、履歴情報記憶部４０及び表示部５０などを備えている。 FIG. 1 is a block diagram showing a configuration example of a weighing system according to an embodiment of the present invention. The weighing system according to the present embodiment includes, for example, an electronic balance 1 and a printer 2 connected to the electronic balance 1. The electronic balance 1 includes a load detection unit 10, a control unit 20, a measurement result storage unit 30, a history information storage unit 40, a display unit 50, and the like.
　荷重検出部１０は、秤量皿（図示せず）に載置される測定対象物の荷重を検出する。荷重検出部１０は、例えば電磁式又はロードセル式であり、秤量皿に測定対象物を載置したときの電気信号の変化を検出することができる。制御部２０は、例えばＣＰＵ（Central Processing Unit）を含む構成であり、ＣＰＵがプログラムを実行することにより、質量測定部２１、画像データ生成部２２、表示制御部２３、テキストデータ生成部２４及びプリント出力部２５などとして機能する。 The load detection unit 10 detects the load of the measurement object placed on the weighing pan (not shown). The load detection unit 10 is, for example, an electromagnetic type or a load cell type, and can detect a change in an electrical signal when a measurement object is placed on a weighing pan. The control unit 20 includes, for example, a CPU (Central Processing Unit), and when the CPU executes a program, the mass measurement unit 21, the image data generation unit 22, the display control unit 23, the text data generation unit 24, and the print It functions as the output unit 25 or the like.
　質量測定部２１は、荷重検出部１０により検出される荷重に基づいて測定対象物の質量を測定する。具体的には、荷重検出部１０により検出される電気信号の変化量が質量に換算されることにより、測定対象物の質量が算出される。質量測定部２１により測定された測定対象物の質量の値は、例えばＲＡＭ（Random Access Memory）により構成された測定結果記憶部３０に計量値として記憶される。 The mass measurement unit 21 measures the mass of the measurement object based on the load detected by the load detection unit 10. Specifically, the mass of the measurement object is calculated by converting the change amount of the electrical signal detected by the load detection unit 10 into mass. The value of the mass of the measurement object measured by the mass measurement unit 21 is stored as a measurement value in the measurement result storage unit 30 configured by, for example, a RAM (Random Access Memory).
　このとき、測定結果記憶部３０には、計量値に対応付けて測定情報が記憶される。測定情報には、測定時の条件又は状態の情報が含まれる。測定時の条件としては、測定時の電子天秤１の各種設定を例示することができる。また、測定時の状態としては、例えば測定の日付、測定の時刻又はユーザの識別情報などを例示することができる。 At this time, measurement information is stored in the measurement result storage unit 30 in association with the measurement value. The measurement information includes information on conditions or states at the time of measurement. As conditions at the time of measurement, various settings of the electronic balance 1 at the time of measurement can be exemplified. Moreover, as a state at the time of a measurement, the date of measurement, the time of measurement, or user's identification information etc. can be illustrated, for example.
　画像データ生成部２２は、測定結果記憶部３０に記憶されている計量値及び対応する測定情報に基づいて、画像表示用の画像データを生成する。この画像データ生成部２２の処理により、ＪＰＥＧデータなどの圧縮画像データ、又は、ＢＭＰデータなどの非圧縮画像データが、表示部５０に表示可能な所定の画像サイズで生成される。画像データ生成部２２により生成された画像データは、表示制御部２３により表示部５０に表示される。表示部５０は、例えば液晶表示器により構成されている。 The image data generation unit 22 generates image data for image display based on the measurement values stored in the measurement result storage unit 30 and the corresponding measurement information. By the processing of the image data generation unit 22, compressed image data such as JPEG data or uncompressed image data such as BMP data is generated with a predetermined image size that can be displayed on the display unit 50. The image data generated by the image data generation unit 22 is displayed on the display unit 50 by the display control unit 23. The display unit 50 is configured by a liquid crystal display, for example.
　テキストデータ生成部２４は、測定結果記憶部３０に記憶されている計量値及び対応する測定情報に基づいて、印刷用のテキストデータを生成する。このテキストデータがプリント出力部２５からプリンタ２に出力されることにより、測定結果が印刷される。テキストデータは、汎用の文書形式であるテキスト形式で保存されるため、汎用のプリンタ２を用いて印刷することができる。プリンタ２は、例えばロール紙に対してドットインパクト方式で印刷を行う。 The text data generation unit 24 generates text data for printing based on the measurement value stored in the measurement result storage unit 30 and the corresponding measurement information. The text data is output from the print output unit 25 to the printer 2, whereby the measurement result is printed. Since the text data is stored in a text format that is a general-purpose document format, the text data can be printed using the general-purpose printer 2. For example, the printer 2 performs printing on roll paper by a dot impact method.
　本実施形態では、画像データ生成部２２により生成された画像データが、履歴情報として履歴情報記憶部４０に記憶される。すなわち、画像表示用として画像データ生成部２２により生成された画像データが、履歴保存のために履歴情報記憶部４０に記憶される。画像データ生成部２２は各測定時に画像データを生成し、１回又は複数回分の測定時における画像データが履歴情報記憶部４０に記憶される。履歴情報記憶部４０に記憶されている画像データは、所定のデータ量を超えた場合に、古い画像データから順に自動的に削除されてもよい。 In the present embodiment, the image data generated by the image data generation unit 22 is stored in the history information storage unit 40 as history information. That is, the image data generated by the image data generation unit 22 for image display is stored in the history information storage unit 40 for history storage. The image data generation unit 22 generates image data at each measurement, and the history information storage unit 40 stores the image data at one or more measurements. The image data stored in the history information storage unit 40 may be automatically deleted in order from the oldest image data when a predetermined amount of data is exceeded.
　このように、本実施形態では、履歴情報として画像データを履歴情報記憶部４０に記憶することにより、テキストデータを記憶する場合よりもデータの改竄を抑制することができる。すなわち、テキストデータの場合には、キーボードなどを用いて数値や文字を容易に書き換えることができるが、画像データの場合には、画像の編集を行わなければデータを改竄することができないため、データの改竄を効果的に抑制することができる。 As described above, in the present embodiment, by storing image data as history information in the history information storage unit 40, data tampering can be suppressed more than when text data is stored. That is, in the case of text data, numerical values and characters can be easily rewritten using a keyboard or the like. However, in the case of image data, the data cannot be altered unless the image is edited. Can be effectively suppressed.
　また、履歴情報として記憶される画像データには、測定結果である測定対象物の質量（各測定時の計量値）だけでなく、測定時の条件又は状態などの測定情報が含まれている。テキストデータでは記憶できないような測定情報も、画像データであれば記憶できる場合があるため、より多くの情報を履歴情報として保存することができる。 Further, the image data stored as the history information includes not only the mass of the measurement object (measured value at each measurement) as a measurement result but also measurement information such as a measurement condition or state. Measurement information that cannot be stored with text data may be stored with image data, so that more information can be stored as history information.
　画像データに含まれる測定時の条件の情報としては、各測定時における電子天秤１の各種設定を表す文字表示や数値表示の他、それらの情報を視覚的に表したグラフ表示又は記号表示などを例示することができる。また、画像データに含まれる測定時の状態の情報としては、測定の日付、測定の時刻又はユーザの識別情報などを表す文字表示や数値表示の他、測定時の状態を視覚的に表したグラフ表示又は記号表示などを例示することができる。 As information on the measurement conditions included in the image data, in addition to character display and numerical display representing various settings of the electronic balance 1 at each measurement, graph display or symbol display that visually represents the information. It can be illustrated. In addition, as information on the state at the time of measurement included in the image data, a graph that visually represents the state at the time of measurement in addition to text display and numerical display indicating the date of measurement, time of measurement or user identification information, etc. Display or symbol display can be exemplified.
　このように、履歴情報として記憶される画像データには、測定の日付、測定の時刻、グラフ表示及びユーザの識別情報の少なくとも１つが含まれていることが好ましい。これらの情報は、特に改竄を防止する必要性が高い測定情報であるため、画像データで記憶することにより効果的に改竄を抑制することができる。また、グラフ表示は、テキストデータでは記憶できない測定情報であるが、画像データであれば記憶することができる。 As described above, it is preferable that the image data stored as the history information includes at least one of the measurement date, the measurement time, the graph display, and the user identification information. Since these pieces of information are measurement information that is highly necessary to prevent tampering, it is possible to effectively suppress tampering by storing them as image data. The graph display is measurement information that cannot be stored in text data, but can be stored in the case of image data.
　図２は、画像データ生成部２２により生成される画像データの一例を示した図である。この例では、測定結果である計量値６０の他、最小計量値６１、応答性設定６２、印刷設定６３、はかりとりモード設定６４、統計モード設定６５、ゼロトラッキング設定６６、警告情報６７、電源情報６８、保存情報６９、測定時刻７０、ユーザ名７１、計量情報７２及び合否情報７３などが画像データに含まれている。 FIG. 2 is a diagram illustrating an example of image data generated by the image data generation unit 22. In this example, in addition to the measurement value 60 as the measurement result, the minimum measurement value 61, the response setting 62, the print setting 63, the weighing mode setting 64, the statistical mode setting 65, the zero tracking setting 66, the warning information 67, and the power supply information 68, stored information 69, measurement time 70, user name 71, measurement information 72, pass / fail information 73, and the like are included in the image data.
　最小計量値６１は、例えば数値表示であり、一定の精度以上で測定を行うことができる最小の計量値を表示している。応答性設定６２は、例えばグラフ表示であり、測定時の応答性の設定をアナログバーで表示している。 The minimum measurement value 61 is, for example, a numerical display, and displays the minimum measurement value that can be measured with a certain accuracy or more. The responsiveness setting 62 is, for example, a graph display, and the responsiveness setting at the time of measurement is displayed with an analog bar.
　印刷設定６３は、例えば記号表示であり、自動的に印刷を行う設定などが行われていることを表示している。はかりとりモード設定６４は、例えば記号表示であり、測定対象物の状態ごと（固体又は粉体など）に適したモードの設定が行われていることを表示している。統計モード設定６５は、例えば記号表示であり、計量値の平均又は偏差などを算出する設定が行われていることを表示している。ゼロトラッキング設定６６は、例えば記号表示であり、秤量皿に測定対象物が載置されていない状態での微小な荷重変動時にゼロ表示を維持する設定が行われていることを表示している。警告情報６７は、例えば記号表示であり、温度の変化量が一定値以上であるなどの警告を表示している。電源情報６８は、例えば記号表示であり、電池の残量などの電源の状態を表示している。保存情報６９は、例えば記号表示であり、外部の記憶装置にデータを記憶していることなどを表示している。 The print setting 63 is, for example, a symbol display, and displays that a setting for automatically printing is performed. The weighing mode setting 64 is, for example, a symbol display, and indicates that a mode suitable for each state of the measurement object (solid or powder) is set. The statistical mode setting 65 is, for example, a symbol display, and displays that the setting for calculating the average or deviation of the measurement value is performed. The zero tracking setting 66 is, for example, a symbol display, and indicates that a setting for maintaining the zero display is performed when a minute load fluctuation occurs in a state where the measurement object is not placed on the weighing pan. The warning information 67 is, for example, a symbol display, and displays a warning that the amount of change in temperature is a certain value or more. The power supply information 68 is, for example, a symbol display and displays a power supply state such as a remaining battery level. The saved information 69 is, for example, a symbol display, and displays that data is stored in an external storage device.
　測定時刻７０は、例えば数値表示であり、測定を行ったときの時刻を表示している。ユーザ名７１は、例えば文字表示であり、測定を行ったユーザの名前を識別情報として表示している。ただし、測定時刻７０は、測定の時刻だけでなく、測定の日付も含んでいてもよい。また、ユーザの識別情報は、ユーザの名前に限らず、ユーザに割り当てられた番号などの他の識別情報であってもよい。 The measurement time 70 is a numerical value display, for example, and displays the time when the measurement was performed. The user name 71 is a character display, for example, and displays the name of the user who performed the measurement as identification information. However, the measurement time 70 may include not only the measurement time but also the measurement date. The user identification information is not limited to the user name, but may be other identification information such as a number assigned to the user.
　計量情報７２は、例えばグラフ表示であり、測定可能な質量の範囲と計量値との関係をアナログバーで表示している。この例では、表示画面の左端から右端までが測定可能な質量の範囲に設定され、計量値が横方向に延びる線の長さで表されている。合否情報７３は、例えばグラフ表示であり、検品時の合否を判定する際に、合格の基準となる質量の範囲と計量値との関係をアナログバーで表示している。この例では、上下方向に延びる目盛により合格の基準となる質量の範囲が表され、その目盛に対する矢印で計量値が表されている。計量値が合格の基準となる質量の範囲内である場合には、例えばチェックボックス７４にチェックが表示される。 The weighing information 72 is, for example, a graph display, and displays the relationship between the measurable mass range and the measured value with an analog bar. In this example, the range from the left end to the right end of the display screen is set to a measurable mass range, and the measurement value is represented by the length of a line extending in the horizontal direction. The pass / failure information 73 is, for example, a graph display, and displays the relationship between the mass range and the measured value as an acceptance criterion when determining pass / fail at the time of inspection with an analog bar. In this example, a range of mass that is a criterion for acceptance is represented by a scale extending in the vertical direction, and a measurement value is represented by an arrow with respect to the scale. If the measured value is within the mass range that is a criterion for acceptance, for example, a check is displayed in the check box 74.
　図３は、別の実施形態に係る計量システムの構成例を示したブロック図である。本実施形態では、履歴情報記憶部４０が電子天秤１に備えられているのではなく、電子天秤１の外部に備えられている点が上記実施形態とは異なっている。そのため、本実施形態における電子天秤１の制御部２０には、画像データ生成部２２により生成された画像データを外部に出力する画像データ出力部２６が備えられている。他の構成は上記実施形態と同様であるため、同様の構成については、図に同一符号を付して詳細な説明を省略する。 FIG. 3 is a block diagram showing a configuration example of a weighing system according to another embodiment. This embodiment is different from the above embodiment in that the history information storage unit 40 is not provided in the electronic balance 1 but is provided outside the electronic balance 1. Therefore, the control unit 20 of the electronic balance 1 in this embodiment is provided with an image data output unit 26 that outputs the image data generated by the image data generation unit 22 to the outside. Since other configurations are the same as those in the above embodiment, the same reference numerals are given to the same configurations, and detailed description thereof is omitted.
　本実施形態における履歴情報記憶部４０は、例えばＵＳＢ（Universal Serial Bus）メモリや外部のハードディスクなどにより構成されている。画像データ出力部２６は、電子天秤１に備えられた接続部（図示せず）を介して、外部の履歴情報記憶部４０に画像データを出力して記憶させる。ただし、画像データ出力部２６は、有線に限らず、無線で画像データを出力するような構成であってもよい。 The history information storage unit 40 in the present embodiment is configured by, for example, a USB (Universal Serial Bus) memory or an external hard disk. The image data output unit 26 outputs and stores image data in an external history information storage unit 40 via a connection unit (not shown) provided in the electronic balance 1. However, the image data output unit 26 is not limited to being wired, and may be configured to output image data wirelessly.
　本実施形態では、各測定時に表示部５０に表示される画像データを外部に出力し、外部の記憶部（履歴情報記憶部４０）に履歴情報として記憶させることができる。このような構成においても、履歴情報として画像データを記憶することにより、テキストデータを記憶する場合よりもデータの改竄を抑制することができる。 In the present embodiment, the image data displayed on the display unit 50 during each measurement can be output to the outside and stored as history information in an external storage unit (history information storage unit 40). Even in such a configuration, by storing image data as history information, it is possible to suppress falsification of data compared to storing text data.
　以上の実施形態では、電子天秤１に備えられた表示部５０に測定結果を表示させるような構成について説明した。しかし、このような構成に限らず、例えば電子天秤１とは別に設けられた表示部に測定結果を表示させるような計量システムであってもよい。この場合、表示部５０に表示させる画像データは、電子天秤１に備えられた制御部２０において生成するような構成に限らず、電子天秤１とは別に設けられた制御部（画像データ生成部）において生成されるような構成であってもよい。 In the above embodiment, the configuration in which the measurement result is displayed on the display unit 50 provided in the electronic balance 1 has been described. However, the present invention is not limited to such a configuration, and for example, a measurement system that displays measurement results on a display unit provided separately from the electronic balance 1 may be used. In this case, the image data to be displayed on the display unit 50 is not limited to a configuration that is generated by the control unit 20 provided in the electronic balance 1, and a control unit (image data generation unit) provided separately from the electronic balance 1. It may be the configuration as generated in
　また、テキストデータ生成部２４及びプリント出力部２５は、制御部２０に備えられていなくてもよい。例えば、測定結果を表示部５０に表示させるだけで、プリンタ２に出力する機能を有していないような電子天秤１であれば、テキストデータ生成部２４及びプリント出力部２５を省略することが可能である。 Further, the text data generation unit 24 and the print output unit 25 may not be provided in the control unit 20. For example, the text data generation unit 24 and the print output unit 25 can be omitted if the electronic balance 1 does not have a function of outputting the measurement result to the printer 2 only by displaying the measurement result. It is.
