     DESCRIPTION OF THE EMBODIMENTS 
     According to the viewpoints of the inventors of the present invention, a record of an experiment in the form of experiment notes can be subjective and has room for human errors on the part of an experimenter, and verification of the result of an important experiment requires immense time and labor in some cases. In addition, demanding experiment notes to be an accurate and adequate record burdens an experimenter, and can cause a drop in the work efficiency of an experiment and the productivity of research activity itself. 
     Therefore, the inventors of the present invention have invented a novel and creative experimental data recording device and the like as a result of performing extensive research and development into recording the record of an experiment that is based on a protocol with objectivity and high reliability. This experimental data recording device and the like are described below in detail by way of an embodiment of the present invention with reference to the drawings. 
       FIG. 1  is a block diagram for illustrating the physical configuration of an experimental data recording device  1  according to the embodiment of the present invention. The experimental data recording device  1  itself may be a dedicated device. However, in this case, the experimental data recording device  1  is implemented by using a common computer. In other words, a commercially-available computer configured to execute a computer program for causing the computer to operate as the experimental data recording device  1  is used for the experimental data recording device  1 . The computer program is in general provided in the form of application software, and is used when installed on the computer. The application software may be provided by recording the application software on a compact disc read-only memory (CD-ROM), a digital versatile disc (DVD) ROM, or another suitable computer-readable information recording medium. Further, the application software may be provided over various information communication networks, such as the Internet. In addition, the functions of the application software may be provided by a server at a remote location over an information communication network, that is, may be implemented by so-called cloud computing. 
     The configuration illustrated in  FIG. 1  is a general computer used as the experimental data recording device  1 . In the computer, a central processing unit (CPU)  1   a,  a random access memory (RAM)  1   b,  an external storage device  1   c,  a graphics controller (GC)  1   d,  an input device  1   e,  and an input/output (I/O)  1   f  are connected to one another by a data bus  1   g  so that the devices can exchange electric signals therebetween. In this case, the external storage device  1   c  is a device capable of statically recording information, for example, a hard disk drive (HDD) or a solid state drive (SSD). Further, signals from the GC  1   d  are output and displayed as an image on a monitor  1   h,  for example, a flat panel display, which allows the user to visually recognize the image. The input device  1   e  is a device, for example, a keyboard, a mouse, or a touch panel, which allows the user to input information. The I/O  1   f  is an interface that allows the experimental data recording device  1  to exchange information with an external device. 
       FIG. 2  is a function block diagram of the experimental data recording device  1  according to this embodiment. The function blocks illustrated in  FIG. 2  focus on the functions of the experimental data recording device  1 . The experimental data recording device  1  does not necessarily have physical components that correspond to respective function blocks on a one-to-one basis. Some function blocks are implemented by an information processing device, for example, the CPU  1   a  of the experimental data recording device  1 , executing specific software. Further, some function blocks are implemented by a specific storage area being allocated to an information storage device, for example, the RAM  1   b  of the experimental data recording device  1 . 
     The experimental data recording device  1  includes a protocol data storage unit  10  configured to store protocol data, which is electronic data representing a protocol, and an experimental data storage unit  11  configured to store experimental data, in order to record experimental data obtained in an experiment in association with protocol data that represents a protocol on which the experiment is based. The term protocol means work procedures and conditions of pretreatment or other types of operation performed on a sample in biochemistry, biotechnology, or a similar field. A protocol is written so that a given experiment is conducted by executing individual procedures that are included in the protocol under specified conditions in a specified order. A person who conducts or plans an experiment in biochemistry, biotechnology, or a similar field (not limited to experiments in the narrow sense but includes performing given treatment on a sample or a reagent by specific procedures, and the act of production and manufacture is also included) writes a protocol usually for the purpose of, for example, conducting the experiment as planned or recording and conveying details of the experiment. A protocol here is therefore not limited to any particular form of description as long as at least one work procedure or others are included. The number, quality, details, and the like of work procedures included in a protocol depend on the intention of a person who creates the protocol, and are accordingly not limited as well. The technical field in which a protocol here is used is not limited to biochemistry and biotechnology. In the present application, however, the technical field includes at least one of biochemistry and biotechnology. Protocol data of a protocol includes a protocol ID, which is information used to uniquely identify the protocol, and procedure data, which represents each procedure included in the protocol. Experimental data means various types of information about an experiment based on a protocol, for example, the experiment itself, various conditions of the experiment, and operation records of various pieces of equipment used in the experiment. In particular, experimental data of an experiment includes an experiment ID, which is information used to uniquely identify the experiment itself, and operation records of various pieces of equipment used in the experiment. 
     The protocol data storage unit  10 , or a protocol server  32 , which is described later, or both may store one or more pieces of protocol data associated with a protocol ID, and may have functions similar to those of a common database, for example, the function of identifying protocol data from a protocol ID. 
     The experimental data recording device  1  includes various recording units configured to record, in an experiment, various types of information that are included in experimental data. An experiment ID recording unit  12  is configured to record, when an experiment is conducted, an experiment ID as experimental data in the experimental data storage unit  11  in association with a protocol ID. The association specifically indicates that an experiment identified from an experiment ID has been conducted based on a protocol identified from a protocol ID by including the protocol ID and the experimental ID both in experimental data. Alternatively, protocol data itself may be added to experimental data. An experimental ID is issued for each experiment by an experiment ID issuing unit  13 . 
     The experimental data storage unit  11 , or an experimental data storage device  26 , which is described later, or both may store one or more pieces of experimental data associated with a protocol ID and an experiment ID, and may have functions similar to those of a common database, for example, the function of identifying experimental data from an experiment ID and the function of identifying experimental data from a protocol ID. 
     The experiment ID issuing unit  13  may be configured to generate an experiment ID on its own, or may be configured to obtain an experiment ID that is generated by an external experiment ID generation device  24  connected via a communication unit  20 . Experiment IDs that are unique throughout separate experimental data recording devices  1  can be issued while avoiding duplication by installing the experiment ID generation device  24  as a Web server that is communicable over the Internet or other telecommunication lines and that is shared fay a plurality of experimental data recording devices  1 . The uniqueness of each experiment ID may instead be ensured by putting some kind of restriction on experiment IDs issued by the experiment ID issuing unit  13 , for example, using an ID that is set uniquely to each experimental data recording device  1  as part of an experiment ID. In any case, an experiment ID is issued as an ID unique to each experiment, and various types of information described below as information included in experimental data are recorded in association with the unique experiment ID. As such, it is clearly recorded that which experiment is associated with these various types of information. 
     An experiment environment data recording unit  14  is configured to record experiment environment data about an experiment in the experimental data recording unit  11  as experiment data. Experiment environment data is data indicating conditions about an experiment itself, and includes at least data that indicates one of an experimenter, an experiment location, an experiment date/time, and experiment equipment. The experimenter is information used to identify a person who has conducted the experiment himself/herself or a person who is in charge of the experiment. The experiment location is information used to identify a place, for example, a building or a room in which the experiment has been conducted, or a booth number. The experiment date/time is information used to identify a date/time at which the experiment has been conducted, and may include a time at which the experiment has started and, additionally, a time at which the experiment has ended. The data indicating experiment equipment is information used to identify pieces of experiment equipment that have been used in the experiment. For example, when experiment equipment that is used is an electronic pipette as described later, an ID unique to the electronic pipet, for example, a serial number, qualifies as information for identifying a piece of experiment equipment. When an experiment uses a plurality of pieces of experiment equipment, for example, a plurality of electronic pipettes or an electronic pipette plus a microscope, all IDs unique to the respective pieces of experiment equipment may be included in experiment environment data as data that indicates experiment equipment. Experiment environment data, along with other types of data, can be utilized as important data indicating that an experiment has been conducted authentically. 
     A target sample ID recording unit  15  is configured to record a target sample ID, which is information used to identify a sample that has been employed in an experiment, in the experimental data storage unit  11  as experimental data. A resultant sample ID recording unit  16  is configured to record, as experimental data in the experimental data storage unit  11 , a resultant sample ID, which is information used to identify an experiment result sample that is obtained as a result of performing various types of operation on a sample employed in an experiment. A target sample used in an experiment and a resultant sample obtained as a result of the experiment can be identified correctly in this manner. The target sample ID and the resultant sample ID can be, for example, container identification information that is attached to a test tube, a petri dish, or a similar container in which a sample is contained and that is read by a reader  17 . 
     An operation record recording unit  18  is configured to record operation records of various pieces of equipment used in an experiment as experimental data in the experimental data storage unit  11 . An operation record is a record of the operation of a piece of experiment equipment  19  used in an experiment, and is received by a reception unit  21  via the communication unit  20 . A specific example of the operation record is described later. The operation record recording unit  18  stores each of operation records, which are for recording that individual procedures included in a protocol have actually been executed with the use of specific pieces of experiment equipment  19 , in association with a corresponding piece of procedure data in protocol data. Which operation record included in experimental data is associated with which one of a plurality of procedures included in a protocol can be identified in this manner. 
     An analysis data recording unit  22  is configured to record, after an experiment is finished, as experimental data in the experimental data storage unit  11 , analysis data, which is information obtained by analyzing a resultant sample with the use of an external analyzer  23 . The analysis data recording unit  22  records the analysis data in association with a resultant sample ID in order to identify the sample analyzed by the analyzer  23 . The analysis data may include, in addition to information about the analyzed sample, information about the environment of the analysis, for example, an ID for identifying the analyzer used in the analysis, and information indicating various analysis conditions and the date/time of the analysis. This means that not only the facts of an experiment but also the obtained result can be evaluated from experimental data. This also means that, because each resultant sample ID is associated with an experiment ID, the analysis data is associated with an experiment ID as well. 
     An experimental data housing unit  25  is configured to store, in the external experimental data storage device  26 , via the communication unit  20 , the pieces of experimental data that are recorded by the respective recording units described above and that are stored in the experimental data storage unit  11 . When the experimental data storage device  26  is installed as a Web server communicable over the Internet or other telecommunication lines, the stored experimental data can be viewed on devices other than the experimental data recording device  1 , and can also be viewed by people other than the experimenter. In order to secure the confidentiality of experimental data and to control who is allowed to view experimental data, experimental data stored in the experimental data storage device  26  may be password-protected, or the viewing of the experimental data may be limited to people who have an associated viewing authorization by putting a viewing restriction on the experimental data. At the time the experimental data is stored by the experimental data housing unit  25 , it is recommended to perform suitable anti-tampering processing on the experimental data through an anti-tampering unit  33 . The anti-tampering unit  33  is configured to prevent the tampering of electronic data by performing known anti-tampering processing on experimental data, for example, attaching an electronic certificate or attaching a hash value that is calculated from an undisclosed hash function. In this manner, artificial manipulation of experimental data and data corruption can be detected, and the reliability and accuracy of experimental data are maintained. 
     The communication unit  20  is configured to hold telecommunication between the experimental data recording device  1  and various external devices. The communication unit  20  is implemented by the I/O  1   f  of  FIG. 1 , and is not limited by whether the communication is cable communication or wireless communication and by what communication standards are used. The communication unit  20  particularly holds communication to and from each piece of experiment equipment  19 , and causes the reception unit  21  to receive an operation record of the equipment  19 . 
     A mid-experiment protocol display unit  27  is configured to display, on the monitor  1   h,  during an experiment, a protocol that is used in the experiment based on protocol data stored in the protocol data storage unit  10 . This allows an experimenter who conducts an experiment by directly operating the experiment equipment  19  to operate the equipment while checking a protocol. Examples of the type of experiment equipment  19  that is to be operated directly by an experimenter include electronic pipettes and microscopes. When the experiment equipment  19  is a robot and a robot control device conducts an experiment automatically by interpreting protocol data, the mid-experiment protocol display unit  27  allows an experimenter who observes the experiment to check which operation included in the protocol is being performed by the robot. 
     A post-experiment protocol display unit  28  is configured to display on the monitor  1   h  a protocol used in an experiment, based on protocol data that is stored in the protocol data storage unit  10 , or protocol data that is included in experimental data stored in the experimental data storage unit  11 . An operation record display unit  29  is configured to display operation records at once on the monitor  1   h  in association with respective procedures that are included in a protocol displayed on the monitor  1   h,  based on experimental data stored in the experimental data storage unit  11 . Displaying a protocol and experimental data on the monitor  1   h  by displaying individual procedures in association with operation records in this manner enables a viewer to immediately grasp how each individual procedure included in the experiment has actually been executed. Analysis data obtained from the external analyzer  23  is further displayed on the monitor  1   h  by an analysis data display unit  30  in association with a resultant sample obtained through the experiment. In this manner, a protocol on which an experiment is based, the history of the experiment, and analysis data obtained as a result of the experiment are displayed in association with one another and, because the displayed pieces of information are associated with one another, a record of the experiment based on the protocol is presented with objectivity and high reliability. The record, which is automatically recorded by the experimental data recording device  1 , also frees an experimenter from an additional burden that is put by a demand to take detailed experiment notes as a record of an experiment. 
       FIG. 3  is a diagram for illustrating an example of a protocol that is displayed on the monitor  1   h  by the display unit  27  or the protocol display unit  28 . As illustrated in  FIG. 3 , a protocol is displayed in a chart format, where procedures included in the protocol, the order of executing the procedures, conditions, and pieces of equipment used in the experiment are shown clearly. A protocol displayed in a chart format is hereinafter referred to as “protocol chart”. The protocol chart illustrated in  FIG. 3  is a part of the whole protocol chart. 
     To give a more detailed description, the protocol chart of this example displays procedures for each container that contains a sample used in the experiment and that is used to perform various types of operation on the sample, with the procedures arranged vertically from top to bottom. The containers used in the experiment are displayed side by side, and it is clearly indicated that a series of procedures along the vertical axis are performed on one container in order. 
     Each container is represented by a symbol  100   a,  which indicates the initial state of the container, and a symbol  100   b,  which indicates the final state of the container. The flow of the container, or a sample contained in the container, is indicated by a vertical arrow that starts from the container symbol  100   a  and points toward the container symbol  100   b.  A procedure performed on the container or the sample contained in the container, is illustrated by a symbol  100   c,  which represents each individual procedure. Each individual procedure is displayed in a visual manner that enables what the procedure is like to be understood easily, by displaying an arrow that branches out of the vertical arrow when the procedure is the operation of taking the content out of the container (for example, “discard”, which means discarding the content), by displaying an arrow that merges into the vertical arrow when the procedure is the operation of adding something to the content of the container (for example, “add”, which means adding a reagent or a similar substance) and by placing the symbol  100   c  on the vertical arrow when the procedure is operation that involves the container alone (for example, “scrape”, which means scraping a cell or “centrifuge”, which means centrifugal separation). Conditions including which reagent is to be used in what amount are displayed in each symbol  100   c.  The order in which procedures are executed in an experiment is determined by places in the arrangement of symbols. Specifically, a symbol at an upper place is given priority in the execution order over a symbol at a lower place, and a symbol on the left is given priority in the execution order over a symbol on the right when the symbols are displayed at the same level. The order of executing procedures is thus also displayed as a unique order. 
     Protocol data stored in the protocol data storage unit  10  includes a protocol ID uniquely assigned to a protocol as the one illustrated in  FIG. 3 , and procedure data representing procedures that are included in the protocol. Procedure data is pieces of data that correspond to the individual symbols illustrated in  FIG. 3 . The mid-experiment protocol display unit  27  interprets protocol data defined as above, and displays a protocol chart on the monitor  1   h  in the mode illustrated in  FIG. 3 . The protocol chart illustrated in  FIG. 3  is an example, and a different format may be used to display a protocol as a format for representing the protocol. However, the employed format at least needs to display each individual procedure included in a protocol independently and clearly. 
       FIG. 4  is a conceptual diagram for illustrating the entire experiment system including the experimental data recording device  1 . In  FIG. 4 , various devices are connected to a wide-area telecommunication line, typically the Internet, in a manner that allows the devices to hold communication among one another. 
     An electronic pipette, which is a piece of equipment operated directly by an experimenter, is connected as an example of the experiment equipment  19  to the experimental data recording device  1  that is illustrated in a lower left part of  FIG. 4 , in order to record on the experimental data recording device  1  an experiment conducted by the experimenter. Protocol data that is created by a separately prepared protocol creation device  31  (alternatively, the experimental data recording device  1  may double as a protocol creation device) may be read into the experimental data recording device  1 . 
     An automatic device, which is a general-purpose robot in this case, is connected as an example of the pieces of experiment equipment  19  to the experimental data recording device  1  that is illustrated in a lower right part of  FIG. 4 , in order to conduct an experiment based on protocol data by automatic control of the robot, and to record the experiment on the experimental data recording device  1 . Protocol data that is accumulated in the protocol server  32 , which is a server connected via the telecommunication line, is downloaded to this experimental data recording device  1 . Based on the downloaded protocol data, the experiment is recorded and the robot may be controlled. The protocol server  32  may accumulate not only protocol data that is created by an experimenter who takes the leading part in the experiment, but also many pieces of protocol data created by the third party. This enables a researcher to easily replicate an experiment conducted by another researcher, to conduct a new experiment by utilizing a protocol that is created by another researcher, and to otherwise make full use of protocols as soft asset. 
     The analyzer  23 , the experiment ID generation device  24 , the experimental data storage device  26 , and other devices may also be connected to the telecommunication line in a manner that allows the devices to hold communication to and from each experimental data recording device  1 . The additionally connected devices are as described above. 
     Through the experiment system described above, experimental data collected and recorded by each experimental data recording device  1  is displayed superimposed on a protocol chart on the monitor  1   h  of the experimental data recording device  1  by the post-experiment protocol display unit  28 , the operation record display unit  29 , and the analysis data display unit  30 , which are illustrated in  FIG. 2 , in response to a request from a user or other triggers.  FIG. 5  is a diagram for illustrating an example of how experimental data is displayed superimposed on a protocol chart. 
     The post-experiment protocol display unit  28  displays a protocol chart on the monitor  1   h  in a manner mostly similar to that of the mid-experiment protocol display unit  27  described above. Here, the same protocol chart as the one illustrated in  FIG. 3  is displayed in  FIG. 5 , and  FIG. 5  is similar to  FIG. 3  also in that a protocol is represented by various symbols  100 . 
     The operation record display unit  29  displays operation records included in experimental data in the vicinity of the respective symbols on the protocol chart. An operation record and a procedure included in the protocol are displayed in association with each other in this manner. In the example of  FIG. 5 , a target sample name (“Sample 1”) and its target sample ID (“1400010”), and a time at which the sample has been prepared are displayed near the upper left symbol  100   a.  The name of a piece of experiment equipment used (“Pipette 4”) and the equipment&#39;s ID (“450341”), which chip has been used and the chip&#39;s ID (“Chip 4340” and “2689912”), an actually measured value of the amount of liquid suctioned and discarded (“627  82  L”), and a time at which the procedure has been executed are displayed near the symbol  100   c  immediately below the upper left symbol  100   a.  Similarly, the ID of a reagent used (“156710”) and a time are displayed near the symbol  100   c  that is below the symbol  100   c  immediately below the upper left symbol  100   a,  and the individual number of a scraper used (“156710”) and a time are displayed near the symbol  100   c  that is further below the former symbol  100   c.  The operation record display unit  29  displays operation records of pieces of experiment equipment in association with individual procedures in this manner, and the displayed operation records each include, among others, what equipment, consumption article, or reagent has been used, a time, and an operation-related amount (the dose or the length of time). 
     The symbol  100   c  yet further below instructs the transfer of the sample between containers. A-photograph of an actual sample taken during the experiment or other images, a temperature, pH, or other physical quantities measured during the experiment, and the like may additionally be displayed as part of an operation record, as indicated by a reference symbol  101 . This enables a viewer to confirm that an experiment based on a protocol has actually been conducted, and to keep track of, in detail, how each procedure has been executed and how a sample has changed in the process. 
     As indicated by a reference symbol  102  above the protocol, various pieces of experiment environment data may be displayed along with the experiment ID and the protocol ID. This ensures that the situation in which the experiment has been conducted, for example, when and by whom the experiment has been conducted, is checked with accuracy. 
     Analysis data is further displayed on the monitor  1   h  by the analysis data display unit  30  along with the protocol chart and the experimental data as indicated by a reference symbol  103 . This analysis data display format, which is given as an example, indicates that the displayed data is analysis data about Sample 1, which has a target sample ID “1400010”, that the resultant sample ID of the analyzed resultant sample is “9400010”, and that the result of the analysis has been determined by some standards as “OK” (for example, determined that the experiment result is reliable). In this example, more detailed information (more exact numerical values and the like) of the experimental data is displayed in place of the analysis data by selecting a section to the upper right of the displayed analysis data in which “LOG” is written. 
     When a series of experiments based on the same protocol is conducted on a plurality of target samples, the screen may switch from the display of data about one target sample to the display of data about another target sample. In the example of  FIG. 5 , tabs  104  are displayed to the upper right of the protocol chart, and experimental data and analysis data of a target sample to be viewed are displayed out of pieces of experimental data and analysis data that are created for each target sample separately, by selecting a tab that is associated with the target sample ID of the target sample to be viewed. Pieces of analysis data about a plurality of target samples may be displayed superimposed on each other for comparison. The screen may switch from data about one resultant sample to data about another resultant sample, instead of data about target samples. 
       FIG. 6  is a flow chart for illustrating the operation of the experimental data recording device  1  that is executed to record experimental data. This flow is given as an example, and not all of the operation steps illustrated in  FIG. 6  are required to be executed. 
     In Step ST 1 , protocol data is first downloaded to the protocol data storage unit  10  from the protocol server  32  or other places to be read. The read protocol data includes a protocol ID and procedure data. 
     In Step ST 2 , the display unit  27  displays a protocol chart based on the read protocol data. 
     In Step ST 3 , the experiment ID issuing unit  13  issues an experiment ID, and the experiment ID recording unit  12  records this experiment ID. The experiment ID issuing unit  13  issues an experiment ID by, for example, causing the experiment ID generation device  24  to generate an experiment ID. 
     In Step ST 4 , the experiment environment data recording unit  14  collects necessary information from various devices, and records the collected information. The devices here vary depending on what information is necessary as experiment environment data. For example, an ID card reader is included among the devices when the experimenter ID is necessary information, and a piece of experiment equipment itself is included among the devices when the ID of experiment equipment used in the experiment is necessary information. 
     In Step ST 5 , the target sample ID recording unit  15  records the ID of a target sample used in the experiment. The target sample ID may be read by, for example, the reader  17 . 
     In Step ST 6 , the reception unit  21  receives operation records of the experiment equipment  19  used in the experiment, and the operation record recording unit  18  records the operation records. The operation records are recorded for the respective procedures included in the protocol, while the procedures are executed. Each operation record collected is recorded in association with a corresponding one of the procedures included in the protocol. 
     In Step ST 7 , the resultant sample ID recording unit  16  records the ID of a resultant sample obtained as a result of the experiment. The resultant sample ID may also be read by the reader  17 , for example. 
     In Step ST 8 , the analysis data recording unit  22  records analysis data obtained from the analyzer  23 . The analysis data is associated with the resultant sample ID of the analyzed resultant sample. 
     In Step ST 9 , the thus obtained experimental data receives anti-tampering processing executed by the anti-tampering unit  33 . In the subsequent Step ST 10 , the experimental data housing unit  25  stores the tampering-proofed experimental data in the experimental data storage device  26 . The experimental data that is associated with a protocol ID and tampering-proofed is automatically recorded in this manner. 
       FIG. 7  is a flow chart for illustrating the operation of the experimental data recording device  1  that is executed to display experimental data superimposed on a protocol chart. This flow is given as an example, and not all of the operation steps illustrated in  FIG. 7  are required to be executed. 
     In Step ST 11 , experimental data to be displayed is first read from the experimental data storage device  26 , and is stored in the experimental data storage unit  11 . This step is unnecessary when experimental data to be displayed is already stored. 
     In the subsequent Step ST 12 , protocol data having a protocol ID that is associated with the experimental data is downloaded from the protocol server  32  and is stored in the protocol data storage unit  10 . Each protocol ID is an ID uniquely assigned to a protocol, and thus the correct protocol used when the experimental data has been obtained is downloaded based on the protocol ID. This step is unnecessary when protocol data is included in the experimental data. 
     In Step ST 13 , the protocol display unit  28  displays a protocol chart. In the subsequent Step ST 14 , the operation record display unit  29  displays operation records in association with symbols that represent procedures in the protocol chart. In Step ST 15 , analysis data is further displayed by the analysis data display unit  30 . The result displayed in this manner is as illustrated in the example of  FIG. 5 . 
     The description given above deals with an example in which the anti-tampering unit  33  performs anti-tampering processing when the experimental data housing unit  25  stores, in the experimental data storage device, experimental data stored in the experimental data storage unit. In a modification example of this embodiment, the anti-tampering processing is enhanced from this example.  FIG. 8  is a function block diagram of the experimental data recording device  1  according to the modification example. 
     In the experimental data recording device  1  according to the modification example, the anti-tampering unit  33  is interposed between the recording units included in the experimental data recording device  1 , here, between the experimental data storage unit  11  and the experiment ID recording unit  12 , the experiment environment data recording unit  14 , the target sample ID recording unit  15 , the resultant sample ID recording unit  16 , the operation record recording unit  18 , and the analysis data recording unit  22 , instead of between the experimental data housing unit  25  and the communication unit  20 . Anti-tampering processing is executed each time the recording units record various types of information. 
     This means that anti-tampering processing is performed also on experimental data that is at the stage of storage in the experimental data storage unit  11  prior to storage in the experimental data storage device  26 . It is therefore very difficult to tamper with experimental data that has not received anti-tampering processing. 
     The anti-tampering processing by the anti-tampering unit  33  in this modification example does not always need to be performed on various types of information recorded by all of the recording units included in the experimental data recording device  1 , and may be performed only on information that is deemed as one requiring anti-tampering. For example, anti-tampering processing may be performed at least each time the operation record recording unit  18  records an operation record. 
     The experimental data recording device  1  according to the embodiment described above executes the operation of displaying experimental data superimposed on a protocol chart in addition to recording. However, according to the viewpoints of the inventors of the present invention, not only experimenters but also the third party who wishes to verify and consult an experiment result demands to view experimental data along with a protocol. When it can be confirmed that an experiment result to be viewed has actually be obtained by conducting the experiment as the protocol dictates, and that the experiment result is authenticate and is guaranteed in objectivity and accuracy, possible advantages including the saving of immense time and labor necessary to verify the result are great for the third party. 
     For that reason, the inventors of the present invention have invented an experimental data display device  2  configured to display experimental data in association with a protocol with objectivity and high reliability, along with the experimental data recording device  1 . The experimental data display device  2  is described below. 
     The physical configuration of the experimental data display device  2  is the same as that of the experimental data recording device  1 , and repetitive descriptions are therefore omitted by referring to  FIG. 1 . The experimental data display device  2  is similar to the experimental data recording device  1  also in that the experimental data display device  2  is implemented by running on a general computer a program that causes the computer to operate as the experimental data display device  2 . 
       FIG. 9  is a function block diagram of the experimental data recording device  2 . The experimental data display device  2  includes configurations common to the experimental data recording device  1  in terms of function. Function blocks in  FIG. 9  that are the same as the ones in  FIG. 2 , which is an illustration of the experimental data recording device  1 , are therefore denoted by the same reference symbols, and repetitive descriptions are omitted. 
     An experiment data reading unit  34  is configured to read, via the communication unit  20 , experimental data to be displayed from the experimental data storage device  26 , and to store the read data in the experimental data storage unit  11 . A protocol data reading unit  35  is configured to read, from the protocol server  32 , protocol data that has a protocol ID associated with the read experimental data and to store the read protocol data in the protocol data storage unit  10 . 
     The post-experiment protocol display unit  28 , the operation record display unit  29 , and the analysis data display unit  30  operate the same way as those of the experimental data recording device  1  described above. The experimental data display device  2  operates the same way as that described with reference to  FIG. 7 . 
     In this manner, protocol data is identified and read based on operation data that is associated with a protocol ID, and the operation data is displayed superimposed on a protocol chart, along with analysis data. Experimental data can consequently be displayed in association with a protocol with objectivity and high reliability. 
     Each of the configurations in the embodiment above is described as a specific example, and the invention disclosed in the present application is not intended to be limited to those specific configurations themselves. Various modifications may be made by a person skilled in the art to the disclosed embodiment. Further, the control illustrated in the disclosed flowcharts may also be appropriately replaced by one having equivalent functions. It should be understood that the technical scope of the invention disclosed in the present application cover all such modifications. It should be understood by those skilled in the art that various modifications, combinations, sub-combinations and alterations may occur depending on design requirements and other factors insofar as they are within the scope of the appended claims or the equivalents thereof.
