  For example, Japanese Patent Laid-Open No. 2005-77093 discloses a spectroscopic measurement unit (hereinafter also referred to as a “measurement unit”) that executes spectroscopic measurement processing, and data processing of measurement data output from the measurement unit while controlling the measurement unit. There is disclosed a spectroscopic measurement system that includes a data processing / control unit (hereinafter also referred to as a “processing control unit”) that can output a result (report) of a quantitative measurement regarding an unknown sample as a printed matter. In this case, the processing control unit includes a central control unit that executes control of the measurement unit and data processing, a memory that temporarily stores calculation results of the central control unit, and a storage device that stores measurement data and various programs ( A hard disk drive device), and an operation unit, a display unit, a printing unit, and the like are connected. Specifically, in this spectroscopic measurement system, the processing control unit is configured by a personal computer in which an existing operating system is installed.

  When creating and printing a report by this spectroscopic measurement system, first, the central control unit in the processing control unit controls the measurement unit according to the processing conditions selected by the operator, and the spectrum for the unknown sample to be analyzed is targeted. Run the measurement process. At this time, the measurement unit performs scan measurement for an unknown sample, acquires a photometric value for each predetermined wavelength step, and outputs the acquired photometric value to the processing control unit as measurement data. . In addition, the measurement data output from the measurement unit is stored in the memory of the processing control unit. Next, the central control unit displays a predetermined dialog box on the display unit, thereby saving the measurement data stored in the memory to the storage device in a file name and a storage location (storage directory (folder), etc.) Request an input operation to indicate

  In addition, when the file name and storage location are instructed by the input operation, the central control unit generates a measurement data file stored in the memory and stores the generated file in the storage device instructed in the storage device. The location is stored with the specified file name. Next, the central control unit causes the measurement unit to execute the photometric measurement process in the same manner as in the spectrum measurement process described above, and the measurement data file is instructed to the designated storage location in the storage device. Remember the file name. Subsequently, the central control unit creates a report based on each measurement data stored in the storage device. The central control unit stores the created report data file in the storage device, and controls the printing unit to print the contents of the report. Thereby, a printed matter of the result (report) of the quantitative measurement regarding the unknown sample is obtained.

Japanese Patent Laying-Open No. 2005-77093 (page 4-6, FIG. 1-4)

  However, the conventional spectroscopic measurement system has the following problems to be solved. That is, in a conventional spectroscopic measurement system, a measurement data file (hereinafter also referred to as a “data file”) output from a measurement unit in a series of processes related to report creation and printing is a directory specified by an operator. In addition, a configuration (method) for storing with a specified file name is adopted. In this case, in a conventional spectroscopic measurement system configured to include a personal computer with an existing operating system installed as a processing control unit, when the data file is stored in the storage device, the central control unit is defined by the operating system. According to the procedure, a process for checking whether or not a file having the same file name as the data file exists in the directory in which the data file is to be stored is executed.

  Specifically, in the conventional spectroscopic measurement system, when the file name of the data file and the storage destination directory are instructed, the central control unit reads the file name information from the directory entry area of the storage device, and The file name specified based on the information (the file name of the file stored in the storage device) is compared with the specified file name (the file name of the data file to be stored in the storage device). It is determined whether or not a file with the designated file name exists in the directory. At this time, if there is no file with the designated file name, the file stored in the storage device at that time is overwritten by the data file to be newly stored (that is, the already stored file is erased). The central control unit stores the data file with the designated file name in the designated directory.

  On the other hand, when a file with the designated file name already exists, the file stored in the storage device at that time may be overwritten by the data file to be newly stored. A display requesting to change either the file name of the data file to be stored or the storage destination directory is displayed on the display unit. At this time, when either the file name or the storage destination directory is changed, the central control unit executes the above check process again for the changed file name or directory. In addition, when an operation for confirming these is performed without changing both the file name and the save destination directory (that is, the operator overwrites an already stored file with a new data file). If accepted, the central control unit stores the data file with the determined file name in the determined directory.

  As described above, in the conventional spectroscopic measurement system, when the data file is stored in the storage device, the central control unit newly stores the file name of the data file to be stored and the file already stored in the storage device (hereinafter, “ The existing file is overwritten with a new data file (except when the operator accepts it) by executing the process of comparing the file name with the existing file (also called “existing file”). ) The situation is avoided. In this case, in this type of apparatus that records measurement data data files, there are many opportunities to generate a large number of the same type of measurement data by executing a plurality of measurement processes on one measurement object. In many cases, a character string indicating the name of a measurement target, a measurement date, or the like is indicated as the file name of each data file, so that a number of data files having the same file name are likely to be stored in one directory. . Therefore, in this type of device, when storing the data file in the storage device, the file with the specified file name is often stored in the specified directory, and as a result, a plurality of times. It may be necessary to change the file name over a period of time.

  However, in the above processing for checking the duplication of the file name according to the procedure defined by the operating system, it takes a certain amount of time to read the file name information from the storage device (information recording medium). Therefore, it takes a long time to compare with the file name of an existing file. Therefore, in the conventional spectroscopic measurement system, a file name that can store the data file in a desired directory is determined without overwriting the existing file with a new data file (without deleting the existing file). As a result, it takes a long time to complete the storage of the data file in a short time.

  The present invention has been made in view of such a problem, and a new data file can be reliably recorded on an information recording medium in a short time without losing an existing data file recorded on the information recording medium. It is a main object to provide a measurement result recording apparatus and a measurement result recording method.

The temporary file name is renamed to the new temporary file name.

  The measurement result recording apparatus according to claim 4 is the measurement result recording apparatus according to any one of claims 1 to 3, wherein the control unit is capable of storing the file name storage area in the second process. When storing a new file name in the file name storage area in a state where is less than the predetermined capacity, the file name stored at the earliest of the file names stored in the file name storage area The new file name is stored in the area where is stored.

The measurement result recording method according to claim 5 is a measurement result recording method for recording the data file on the information recording medium in a measurement result recording apparatus configured to be able to record the data file of the measurement result on the information recording medium. A file name consisting of a file name main body and an extension of the data file to be recorded in any directory on the information recording medium, and the data file recorded in any directory on the information recording medium. when one of the filename body portion and a file name composed of extension after renaming is designated, the file name body portion and extension of the file to be compared among the files recorded on the information recording medium from the information recording medium the file name information that can specify a file name consisting of With out look, or the data file of the temporary file name in comparison with the file name specified on the basis of the file name information a file name the specified as temporary file name is recorded in the one of the directories not The temporary processing is performed without storing a file name that is not a comparison target with the temporary processing file name in the first processing among the first processing for determining whether or not the file name is identified based on the file name information. all both process and second process of storing a file name to be compared with the file name in the file name storage area defined in the storage portion of the measurement result recording unit, is recorded in the one of the directories the running respectively for file, the data file of the temporary file name is recorded in the one of the directories If there is no temporary file name, the process A for determining the temporary file name as an official file name is executed, and when the data file of the temporary file name is recorded in any of the directories, a change rule defined in advance The temporary file name is renamed to a new temporary file name and the data file whose file name is stored in the file name storage area is compared with the file name in the file name storage area and the temporary file name. To determine whether the data file of the temporary file name is recorded in any of the directories, and for the data file whose file name is not stored in the file name storage area, the file name information The temporary file name is compared with the file name specified based on the temporary file name. The process B for determining whether or not the data file with the file name is recorded in any one of the directories is executed, and either the process A or the process B is executed according to the determination result of the process B To do.

  6. The measurement result recording apparatus according to claim 1, and the measurement result recording method according to claim 5, wherein when the data file of the temporary file name is not recorded in “any directory”, the temporary file name is an official file. When the data file with the temporary file name is recorded in “any directory”, the temporary file name is renamed to a new temporary file name and specified in the storage unit. For data files whose file names are stored in the specified file name storage area, compare the file name and temporary file name in the file name storage area, and for data files whose file name is not stored in the file name storage area Is the file name and temporary file name specified based on the file name information read from the information recording medium By performing the comparison, the process B for determining whether the data file with the temporary file name is recorded in “any directory” is executed, and either the process A or the process B is executed according to the determination result of the process B This process is repeated until a formal file name is determined by executing process A.

  Therefore, according to the measurement result recording apparatus according to claim 1 and the measurement result recording method according to claim 5, it is determined whether a data file having the same file name as the temporary file name is recorded in "any directory". When checking, for the number of data files whose file names can be stored in the file name storage area of the data files recorded in the directory, the corresponding file name information is stored once from the information recording medium. The same as the temporary file name, with the file name in the file name storage area that can be read in a shorter time than reading the file name information when comparing with other temporary file names after reading. It is possible to check whether the data file with the file name is recorded in "any directory"As a result, a file name different from the file name of the data file already recorded on the information recording medium can be determined in a short time. As a result, a new data file can be created in a short time without losing the existing data file. Thus, it can be surely recorded on the information recording medium.

According to the measurement result recording apparatus of the second aspect, the file name having an extension different from the extension of the temporary file name is determined to be inconsistent with the temporary file name, and the temporary process in the first process and the process B is determined. By executing the third process and the fourth process excluded from the comparison target with the file name, the extension is different from that of the newly recorded data file, so that the file is erased by recording the data file. As long as unnecessary comparison processing is not performed on a file having no data, a file name different from the file name of the data file already recorded on the information recording medium can be specified in a shorter time.

  Furthermore, according to the measurement result recording apparatus of claim 3, the character string obtained by combining the designated character string and the character string generated according to the generation rule in a predetermined order is designated as the “specified file name”. In the process B, the character string generated in accordance with the above generation rule is changed and the temporary file name is renamed to a new temporary file name. Unlike the configuration (method) in which the control unit changes everything according to the change rules and sets it as a new temporary file name, no matter how the temporary file name is changed, it includes the first character string specified by the user. Since the file name is generated as a temporary file name, the user is informed of the measurement data data file based on the first character string specified by the user. It is possible to determine the file name that can reliably recognize to as an official file names.

  According to the measurement result recording apparatus of the fourth aspect, a new file name is stored in the file name storage area in a state where the storable capacity of the file name storage area falls below a predetermined capacity in the second process. A new data file is recorded by storing the new file name in the area where the file name stored first among the file names stored in the file name storage area is stored. Among the data files recorded in the directory, when comparing the file name of a data file whose file name is not recorded in the file name storage area with the temporary file name, the file name is stored in the file name storage area. Unnecessary processing of skipping file name information for stored data files (from directory entry area The file name information is read out, but it is discarded without performing comparison processing, etc., and the next file name information is read out, and recorded at the head part of the file name information recording area in the directory entry area. Since the file name information can be read out sequentially and compared with the temporary file name, a file name different from the file name of the data file already recorded on the information recording medium can be specified in a shorter time. it can.

2 is a configuration diagram of a measurement result recording apparatus 1. FIG. 4 is an explanatory diagram for explaining each storage area defined in a storage unit 6; FIG. 10 is a flowchart of file name determination processing 20. 10 is a flowchart of file name change processing 40;

  Hereinafter, embodiments of a measurement result recording apparatus and a measurement result recording method will be described with reference to the accompanying drawings.

  A measurement result recording apparatus 1 shown in FIG. 1 includes a measurement unit 2, an operation unit 3, a display unit 4, a control unit 5, and a storage unit 6, and is configured so that a memory card 7 can be attached. Accordingly, the data file (measurement data file D2) indicating the result of the measurement process by the measurement unit 2 can be recorded in the memory card 7. The measurement unit 2 executes measurement processing according to the control of the control unit 5, performs A / D conversion processing on the input signal Si to generate measurement data D 1, and outputs the generated measurement data D 1 to the control unit 5. The operation unit 3 includes operation switches for setting conditions for measurement processing by the measurement unit 2 and for instructing a file name and a directory name when recording a measurement data file D2 in a memory card 7 to be described later. An operation signal corresponding to the operation is output to the control unit 5. The display unit 4 operates according to the control of the control unit 5, an operation condition setting screen for setting the operation condition of the measurement result recording apparatus 1, a measurement result display screen for displaying the result of the measurement process by the measurement unit 2, and a measurement A recording condition instruction screen (none of which is shown) for instructing the recording condition of the data file D2 is displayed.

  The control unit 5 comprehensively controls the measurement result recording apparatus 1. Specifically, the control unit 5 controls the measurement unit 2 to execute measurement processing, and stores the measurement data D1 output from the measurement unit 2 in the storage unit 6. Further, the control unit 5 controls the display unit 4 to display a measurement result (measurement result display screen) based on the measurement data D1. Further, as an example, the control unit 5 is stored in the storage unit 6 when the measurement process by the measurement unit 2 is completed or when an instruction is given from the user by operating the operation unit 3 during the execution of the measurement process. A data recording process for generating a measurement data file D2 based on the measurement data D1 and recording it on the memory card 7 is executed. In this case, in the measurement result recording apparatus 1, when the above-described data recording process is executed or when an operation for renaming the file name of the file (measurement data file D2, etc.) recorded on the memory card 7 is performed. The control unit 5 executes the file name determination process 20 shown in FIG. 3 to determine the file name of the target file.

  The storage unit 6 is an example of a “storage unit”, and is configured by, for example, a semiconductor memory (RAM), and temporarily stores measurement data D1 output from the measurement unit 2, calculation results of the control unit 5, and the like. Remember. In this case, in the measurement result recording apparatus 1, when the control unit 5 executes the file name determination process 20, as shown in FIG. 2, an overlap flag storage area 11, an erase number counter area 12, and a read completion number counter area 13 and a file name storage area 14 are defined in the storage unit 6, and various types of information necessary for determining the file name are stored in these areas. The contents of information stored in the areas 11 to 14 and the timing at which the information is stored will be described in detail later. On the other hand, the memory card 7 is an example of an “information recording medium”, and is configured to be able to store various files including the measurement data file D2. In place of the memory card 7, a configuration is adopted in which the measurement data file D2 and the like are recorded on various information recording media such as a hard disk drive (hard disk), an optical disk drive (optical disk), and a magneto-optical disk drive (magneto-optical disk). be able to.

  In the recording process of the measurement data file D2 by the measurement result recording apparatus 1, first, the operating unit 3 is operated to set the conditions for the measurement process by the measuring unit 2. Next, as an example, when a process start switch (not shown) of the operation unit 3 is operated, the control unit 5 controls the measurement unit 2 according to the set conditions to execute measurement processing. At this time, the measurement unit 2 performs A / D conversion processing on the input signal Si to generate measurement data D1, and sequentially outputs the generated measurement data D1 to the control unit 5. Further, the control unit 5 sequentially stores the measurement data D1 output from the measurement unit 2 in a predetermined area (measurement data storage area) in the storage unit 6, and displays the measurement result based on the measurement data D1 on the display unit. 4 is displayed. Thereafter, the control unit 5 satisfies a preset end condition (when the end time arrives, when a set amount of measurement data D1 is obtained, or the like) or a process (not shown) of the operation unit 3 When the end switch is operated, the measurement unit 2 is controlled to end the measurement process, and the storage process of the measurement data D1 in the storage unit 6 and the display process of the measurement result on the display unit 4 are ended.

  For example, the control unit 5 instructs a recording condition for recording the measurement data file D2 of the measurement data D1 stored in the storage unit 6 on the memory card 7 at the time when the above series of processing is completed. A recording condition instruction screen (not shown) to be displayed is displayed on the display unit 4. Specifically, the control unit 5 displays a recording condition instruction screen on the display unit 4 so that the directory in the memory card 7 in which the measurement data file D2 is recorded and the file name of the measurement data file D2 are arbitrarily included. The character string of At this time, as an example, the measurement data file D2 with a file name including a character string “USER” in a directory “data” (hereinafter, also referred to as “/ data”) by a switch operation of the operation unit 3 is used. Is specified (an example of “when a file name of a data file to be recorded in [any directory] in the information recording medium is designated”). Further, the control unit 5 starts the file name determination process 20 shown in FIG. 3 when the above conditions are instructed.

  In this file name determination process 20, the control unit 5 first clears the file name storage area 14 and the like in the storage unit 6, and uses the character string “USER” instructed by the user to measure the data file. The temporary file name of D2 is determined (step 21). Specifically, the control unit 5 resets the value of the duplication flag and the number of erasures counter by storing the value “0” in the duplication flag storage area 11 and the erasure number counter area 12, respectively. The initial value (for example, a character string terminator) defined in advance is stored in the file name storage area 14 to clear this area.

  In this case, the file name storage area 14 is an area in which the file names to be compared for the sameness in the file names in step 29 to be described later are temporarily stored among the file names of the files recorded on the memory card 7. As an example, it is defined that 1000 file names can be stored. The duplication flag storage area 11 is an area for storing a value of “duplication flag” whose value is changed from “0” to “1” when the file names are determined to be the same in step 29 described later. The erasure number counter area 12 is counted up when it is determined that there is no free area in the file name storage area 14 in step 27 described later, and the file name in the file name storage area 14 is deleted in step 31 described later. This is an area for storing the value of the “erasure number counter”.

  In the measurement result recording apparatus 1, as an example, the extension of the file name of the measurement data file D2 when recording on the memory card 7 or the like is defined as “MEM”. Furthermore, in this measurement result recording apparatus 1, as an example, a character string designated by the user (an example of “designated character string”: a character string “USER” in this example) and “0001” are initialized. As a value, a character string (an example of a “character string generated according to a predetermined generation rule”) indicating a 4-digit numerical value sequentially counted up as “0002”, “0003”... By arranging in order (an example of “predetermined order”), it is defined to generate a character string that constitutes a main body (a part excluding an extension) in a file name. Accordingly, in step 21 described above, the file name “USER0001.MEM” is generated as “specified file name”, and this file name is determined as “temporary file name”. In this example, as described later, the matter that the character string indicating the above four-digit numerical value is sequentially counted up from “0001” to “0002”, “0003”,. Corresponds to "Rule".

  Next, the control unit 5 reads file name information from the directory entry area of the memory card 7 (step 22). At this time, the control unit 5 selects “directory entry” of the file name information of each file (all files including the measurement data file D2 and other files) recorded in “/ data” in the memory card 7. The file name information first recorded in the area (file name information stored in the head part of the file name information recording area in the directory entry area) is read out. Subsequently, the control unit 5 is defined as the extension of the file name specified based on the read file name information (hereinafter also simply referred to as “read file name”) and the extension of the measurement data file D2. It is determined whether or not the extension (“MEM” in this example) is the same (step 23). At this time, when the read file name is “aaaa.txt”, for example, the control unit 5 determines that the extensions do not match.

In this example, since the extensions are different from each other, no matter what character string the body part of the read file name and the body part of the file name of the measurement data file D2 to be recorded later are configured. When the measurement data file D2 is recorded on the memory card 7, the read file name information file is not erased by overwriting the measurement data file D2. Therefore, the control unit 5 excludes the read file name from the comparison target on the assumption that the two file names do not match without comparing the file name main body units (an example of “third process”). , It is determined whether or not the comparison of the file names for all the files recorded in “/ data” has been completed (step 24).

  At this time, if a file other than the file with the file name “aaaa.txt” does not exist in “/ data”, the control unit 5 sets the information (duplicate flag value) in the duplicate flag storage area 11 to “0”. ”(Step 25), the temporary file name“ USER0001.MEM ”is determined as the official file name (step 26), and the file name determination process 20 is terminated. Next, the control unit 5 reads the measurement data D1 from the storage unit 6 to generate the measurement data file D2, and the generated measurement data file D2 is a directory (in this example, designated by the input operation of the operation unit 3). “/ Data”) is recorded with the file name determined in the file name determination process 20 (in this example, the file name “USER0001.MEM”). Thereby, the recording process of the measurement data file D2 is completed.

  On the other hand, in step 23 in the file name determination process 20, it is determined that the extension of the read file name is the same as the extension of the temporary file name (for example, the read file name is “aaaa0001.MEM ”), The control unit 5 determines whether or not a free area exists in the file name storage area 14 of the storage unit 6 (step 27). At this time, it is determined that there is a sufficient storage area in the file name storage area 14, and the control unit 5 determines a character string (in this example, “aaaa0001”) that constitutes the main body part of the read file name. (Character string) is stored in the file name storage area 14 (an example of "second processing": step 28).

  Next, the control unit 5 compares the read file name (the file name specified based on the file name information) with the temporary file name to determine whether or not both file names are the same (“temporary” An example of “first process for determining whether or not a data file with a file name is recorded in [any directory]”: step 29). At this time, since the two file names are not the same, the control unit 5 executes the determination process of step 24 again. At this time, if a file other than the measurement data file D2 having the file name “aaaa0001.MEM” does not exist in “/ data”, the control unit 5 determines that the value is “0” in step 25. The temporary file name “aaaa0001.MEM” is determined as the official file name (an example of “process A”: step 26), and the file name determination process 20 is terminated. As a result, the measurement data file D2 generated based on the measurement data D1 is recorded in “/ data” in the memory card 7 with the file name “aaaa0001.MEM”, and the recording process is completed.

  Further, when it is determined in step 29 of the file name determination process 20 that the read file name (the file name specified based on the file name information) is the same as the temporary file name, the control unit 5 Then, the value “1” is stored in the duplication flag storage area 11 in the storage unit 6 (the duplication flag is set to “1”: step 30). Next, when the control unit 5 executes the above step 24 and determines that the comparison between the file name of the other file recorded in “/ data” and the temporary file name has not been completed, Returning to step 22, the file name information is read. At this time, the file name information of each file (measurement data file D2 and all files including other files) recorded in “/ data” in the memory card 7 is second in the directory entry area. Read the file name information recorded in. Next, the control unit 5 sequentially executes the steps after step 23 described above.

  In this case, when 1000 or more measurement data files D2 are recorded in “/ data”, when the above step 28 is executed 1000 times, an empty area (files already stored in the file name storage area 14). (An area in which a new file name can be stored without deleting the name) disappears (an example of “a state where the storage capacity of the file name storage area falls below a predetermined capacity”). Therefore, when the control unit 5 reads out the file name information about the 1001st measurement data file D2 from the many measurement data files D2 stored in “/ data” from the memory card 7 (step 22). ) After determining that the extension is “MEM” (step 23), it is determined that there is no free area in the file name storage area 14 (step 27).

  At this time, the control unit 5 erases the file name stored first among the 1000 file names stored in the file name storage area 14 and counts up the value in the erase number counter area 12. (Step 31). Next, the control unit 5 stores the file name for the 1001st measurement data file D2 in the area where the file name has been deleted in step 31 (step 28). In addition, after deleting the file name memorize | stored first in step 31, a new file name is memorize | stored in step 28, and a new file name is stored in the area | region where the file name memorize | stored first is memorize | stored. Instead of the above method of storing the file name, a method of directly overwriting the new file name in the area storing the file name stored first can be employed. Subsequently, the control unit 5 determines whether or not the file name and the temporary file name for the 1001st measurement data file D2 are the same (step 29), and then performs each process after step 30 described above. Run.

  On the other hand, as described above, after determining whether or not the comparison between the file names of all the files recorded in “/ data” and the temporary file names has been completed (step 24), the control unit 5 It is determined whether or not the value of the flag is “1” (step 25). At this time, when it is determined that the two file names are not the same in the determination process of step 29 for the file name of each file recorded in “/ data” (that is, the same as the temporary file name). When the measurement data file D2 having the file name does not exist in “/ data”), the process of the above step 30 is not executed, so that the value of the duplicate flag is “0” when the value is cleared in the above step 21. It is a value. Therefore, when the value of the duplication flag is “0”, as described above, the control unit 5 determines the temporary file name as an official file name, and ends the file name determination process 20.

  When the measurement data file D2 having the same file name as the temporary file name exists in “/ data”, the above step 30 is executed after the discrimination process in the above step 29, and the value of the duplicate flag is “1”. " In such an example, when the temporary file name is determined as the official file name, the measurement data file D2 newly recorded on the memory card 7 is an existing measurement data file having the same file name as the temporary file name. The existing measurement data file D2 will be overwritten by overwriting D2. Therefore, the control unit 5 executes the file name change process 40 shown in FIG. 4 when determining that the value of the duplication flag is “1” in the above step 24.

  In this file name changing process 40, the file name determined in the above step 21 is changed to a new temporary file name (renaming the temporary file name: step 41). Specifically, the control unit 5 generates a character string “0001” of the character strings constituting the file name “USER0001.MEM” determined in step 21 (“generated according to a predetermined generation rule). An example of “character string” is counted up to “0002”, and the character string “USER” and the character string “0002” instructed by the user prior to the start of the file name determination process 20 are A file name “USER0002.MEM” is generated by combining the character string “MEM” defined in advance as an extension of the measurement data file D2 by arranging them in order. The file name is determined as a new temporary file name. Thereby, the renaming of the temporary file name is completed.

  Next, the control unit 5 determines whether or not the value of the erase number counter stored in the erase number counter area 12 is “0” (step 42). At this time, when the existing measurement data file D2 exists in “/ data” in the memory card 7 and the number thereof is 1000 or less, all the measurement data files D2 recorded in “/ data” are stored. Since the name can be stored in the file name storage area 14, it is determined in step 27 that there is no free area, and step 31 (deletion of the file name stored in the file name storage area 14 and the number of deletions) (Counter counting up) is never executed. Therefore, when the value of the erasure number counter is “0”, the control unit 5 changes the temporary file name changed (newly determined) in the above step 41 and the file name stored in the file name storage area 14. Are compared (step 43) to determine whether or not both file names are the same (step 44).

  At this time, the time required for reading the file name stored in the file name storage area 14 of the storage unit 6 is the time required for reading the file name information recorded in the directory entry area in the information recording medium such as the memory card 7. Compared with the time required, it is an extremely short time of about several tenths to one hundredths. Therefore, the measurement result recording device for determining whether or not the measurement data file D2 having the temporary file name is recorded in “/ data” by comparing the file name read from the file name storage area 14 with the temporary file name. 1, by comparing the file name specified based on the file name information read from the memory card 7 with the temporary file name, whether or not the measurement data file D2 of the temporary file name is recorded in “/ data”. The file name comparison process can be completed in a very short time compared to determining the file name.

  In this example, from the above step 41 for changing the temporary file name, the file name in the file name storage area 14 is compared with the temporary file name, so that “/ data” has the same file name as the temporary file name. The process up to step 44 described above for determining whether or not the measurement data file D2 is recorded corresponds to “process B”. When the control unit 5 determines in step 44 that the file name stored in the file name storage area 14 is the same as the temporary file name, the control unit 5 returns to step 41 and returns to the temporary file name. To a new temporary file name. At this time, the file name “USER0003.MEM” is determined as a new file name, and the discrimination process of step 42 is executed (“process B” is executed according to the discrimination result of “process B”). Example). If it is determined in step 44 that the two file names are not the same, the control unit 5 ends the file name changing process 40 and officially determines the file name newly determined in step 41. The file name determination process 20 is terminated (an example in which “process A” is executed according to the determination result of “process B”).

  On the other hand, when the value of the erasure number counter is “1” or more in the above step 42 (that is, part of the file names of 1001 or more measurement data files D2 recorded in “/ data” is a file name storage area) 14), since it is determined in step 27 that there is no free space and step 31 is executed, each measurement data file D2 recorded in “/ data” is recorded. As for some of the measurement data files D 2, the file names are not stored in the file name storage area 14. Therefore, when the value of the erase number counter is “1” or more, the control unit 5 first stores the value “0” in the read completion number counter area 13 to reset the value of the read completion number counter. (Step 45). In this case, the read completion number counter area 13 stores the value of the “read completion number counter” that is counted up when the file name information is read from the directory entry area of the memory card 7 or the like in the steps described later. It is an area.

  Next, the control unit 5 reads the file name information from the directory entry area of the memory card 7 (step 46). At this time, the control unit 5 performs the same processing as that at the time of the reading process in step 22 described above on each file (measurement data file D2 and all other files including other files) recorded in “/ data” in the memory card 7. "File name information recorded first in the directory entry area" in the file name information of the file) is read. Subsequently, the control unit 5 determines the extension of the file name (read file name) specified based on the read file name information and the extension defined as the extension of the measurement data file D2 (in this example, “ MEM ") is the same (step 47).

At this time, when the extension of the read file name is not “MEM” (that is, when the file name of the file other than the measurement data file D2 is read in the above step 46), the read file name Regardless of what character string is used for the main body and the main body of the file name of the measurement data file D2 to be recorded later, the file name information read when the measurement data file D2 is recorded on the memory card 7 Is not erased by overwriting the measurement data file D2. Therefore, the control unit 5 excludes the read file name from the comparison target on the assumption that the file names do not match without comparing the file name main body parts (an example of “fourth process”). Returning to step 46, the “second file name information recorded in the directory entry area” of the file name information of each file recorded in “/ data” is read out, and the discrimination process in step 47 is performed. Execute.

  When it is determined in step 47 that the extension of the read file name is the same as the extension of the temporary file name, the control unit 5 compares the read file name with the temporary file name. (Step 48), it is determined whether or not both file names are the same (Step 49). At this time, when the read file name and the temporary file name are the same (that is, when the measurement data file D2 having the same file name as the temporary file name exists in “/ data”), the temporary file name Is the official file name and the measurement data file D2 is recorded in “/ data”, and the file name information read out in step 46 (the existing measurement data file D2 having the same file name as the temporary file name) ) Is erased by recording a new measurement data file D2. Therefore, when the read file name and the temporary file name are the same, the control unit 5 returns to the above step 41, changes the temporary file name to a new temporary file name, and then performs the processing after step 42. Run again.

  On the other hand, when it is determined that the file name read in step 49 is not the same as the temporary file name, the control unit 5 counts up the value of the read completion number counter (step 50) and after the count up It is determined whether or not the value of the read completion number counter matches the value of the erase number counter (step 51).

  In this case, as an example, when 1001 measurement data files D2 are recorded in “/ data”, 1000 measurements executed prior to reading the file name information for the 1001st measurement data file D2 By storing the file name for the data file D2 (step 28), 1000 file names are stored in the file name storage area 14. Therefore, in this example, the file name information for the 1001st measurement data file D2 is read in the process of step 22, and it is determined in the subsequent step 27 that there is no free area in the file name storage area 14. In step 31, the file name stored first is deleted from the file name storage area 14, and the value of the deletion number counter is counted up.

  Therefore, with respect to each measurement data file D2 stored in “/ data”, the file names are stored in the file name storage area 14 except for the measurement data files D2 corresponding to the number of erase number counters. Therefore, the control unit 5 sets the file name and the temporary file name specified based on the file name information read from the directory entry area of the memory card 7 for the measurement data files D2 corresponding to the number of erase number counters. By comparing, it is determined whether or not the file name of the measurement data file D2 matches the temporary file name (an example of “processing B for data file whose file name is not stored in the file name storage area”): Step 48 49).

  In this case, in step 31 described above, instead of the file name stored first in the file names stored in the file name storage area 14, for example, a method of erasing the file name stored last is used. When adopted, when comparing the file name specified based on the 1001st file name information in the directory entry area with the temporary file name, the file specified based on the 1000th file name information in the directory entry area The name is deleted from the file name storage area 14. Therefore, in this example, it is necessary to read out the 1000th file name information from the directory entry area in step 46 described above. Therefore, in order to read out the 1000th file name information, it is necessary to skip 999 unnecessary file name information (file name information in which the corresponding file name is stored in the file name storage area 14). End up.

  On the other hand, in this example in which the file name stored first in the file names stored in the file name storage area 14 is deleted in the above-described step 31, 1001 measurements are made in “/ data”. In the above example in which the data file D2 exists, the file name of the measurement data file D2 corresponding to the file name information initially recorded in the directory entry area is not stored in the file name storage area 14. Therefore, in the above step 46, the file name of the measurement data file D2 whose file name is not stored in the file name storage area 14 can be specified by reading the first file name information from the directory entry area. For this reason, unlike the above-described example in which the latest stored file name is deleted in step 31, the file name comparison for the measurement data file D2 is performed by the amount corresponding to the unnecessary skipping of the file name information. Processing can be performed in a short time.

  On the other hand, by executing the above-described steps 48 and 49 for the number of erase number counters, the read completion number counter value coincides with the erase number counter value in the subsequent step 50. At that time (that is, when the file name comparison process has been completed for the number of erasure counters) (step 51), the control unit 5 executes the processes of steps 43 and 44 described above. As a result, for the measurement data file D2 excluding the number of erasure count counter values in the measurement data file D2 recorded in “/ data”, the file name recorded in the file name storage area 14 and By comparing the temporary file name with the temporary file name, it is determined whether or not the file name of the measurement data file D2 matches the temporary file name ("Processing for data file in which file name is stored in file name storage area" An example of “B”).

  Thereafter, when the control unit 5 determines that the file name in the file name storage area 14 and the temporary file name are not the same in the above step 44, the control unit 5 ends the file name changing process 40 and the temporary file. The name is determined as the official file name (step 26). Next, the control unit 5 reads out the measurement data D1 from the storage unit 6 to generate the measurement data file D2, and stores the generated measurement data file D2 in the directory specified by the input operation of the operation unit 3 in the above file. The file name determined in the name determination process 20 is recorded. Thereby, the recording process of the measurement data file D2 is completed.

  The process for recording a new measurement data file D2 on the memory card 7 has been described. However, the measurement data file D2 recorded in “any directory” in the memory card 7 (the existing measurement data file D2 When the file name after the renaming is designated, the above file name determination process 20 is executed to check the duplication of the file name and determine the official file name. As a result, the file name of the existing measurement data file D2 is renamed to a new file name determined by the file name determination process 20.

  As described above, in the measurement result recording apparatus 1 and the measurement result recording method in the measurement result recording apparatus 1, the temporary file name is obtained when the measurement data file D2 having the temporary file name is not recorded in "any directory". Is executed as a formal file name, and when the measurement data file D2 of the temporary file name is recorded in “any directory”, the temporary file name is changed to a new temporary file name. In addition to renaming, for the measurement data file D2 whose file name is stored in the file name storage area 14 defined in the storage unit 6, the file name and temporary file name in the file name storage area 14 are compared, and the file For the measurement data file D2 whose file name is not stored in the name storage area 14, from the memory card 7. “Processing B” for determining whether the measurement data file D2 of the temporary file name is recorded in “any directory” by comparing the file name specified based on the extracted file name information and the temporary file name. And repeat the process of executing either “process A” or “process B” according to the determination result of “process B” until the formal file name is determined by executing “process A”. .

  Therefore, according to the measurement result recording apparatus 1 and the measurement result recording method, the measurement data file D2 having the same file name as the temporary file name is stored in “any directory” (“/ data” in the above example). When checking whether it is recorded, the number of measurement data files D2 that can be stored in the file name storage area 14 in the measurement data file D2 recorded in the directory corresponds. A file in the file name storage area 14 that can be read out in a shorter time than reading out the file name information when the file name information is read once from the memory card 7 and then compared with other temporary file names. As a comparison target, the measurement data file D2 having the same file name as the temporary file name is “any directory. It is possible to check whether it is recorded in the Li ". For this reason, a file name different from the file name of the measurement data file D2 already recorded in the memory card 7 can be determined in a short time. As a result, a new measurement can be performed without losing the existing measurement data file D2. The data file D2 can be reliably recorded on the memory card 7 in a short time.

  Further, according to the measurement result recording apparatus 1, it is determined that the file name having an extension different from the extension of the temporary file name does not match the temporary file name, and the “first process” and “process B” are performed. By excluding it from the comparison target with the temporary file name, the extension of the measurement data file D2 to be newly recorded is different, so that the file that is not deleted by the recording of the measurement data file D2 is unnecessary. A file name that differs from the file name of the measurement data file D2 already recorded in the memory card 7 by the amount not subjected to the processing (comparison processing of the main body of the file name or storage processing in the file name storage area 14). It can be specified in a shorter time.

  Further, according to the measurement result recording apparatus 1, a character string specified by the user (in the above example, a character string “USER”) and a character string generated according to the generation rule (in the above example, “0001”). A character string (in this example, a character string such as “USER0001”) that is combined with a four-digit numerical value such as “” in a predetermined order is designated as the “specified file name”. In the “Process B”, the character string generated according to the above generation rule is changed and the temporary file name is renamed to a new temporary file name. Unlike the configuration (method) in which the control unit 5 changes all the character strings to be changed in accordance with the change rule to make a new temporary file name, the user first designates no matter how the temporary file name is changed. String Since the included file name is generated as a temporary file name, the user is surely recognized what measurement data file D2 is based on the character string initially specified by the user. The file name to be obtained can be determined as the official file name.

  Further, according to the measurement result recording apparatus 1, the file is stored in a state where the storable capacity of the file name storage area 14 is less than a predetermined capacity in the “second processing” (the free area no longer exists). When a new file name is stored in the name storage area 14, a new file name is stored in the area storing the file name stored first among the file names stored in the file name storage area 14. By storing, the file name of the measurement data file D2 in which the file name is not recorded in the file name storage area 14 among the measurement data files D2 recorded in the directory in which the new measurement data file D2 is recorded. And the temporary file name are compared with the measurement data file D2 in which the file name is stored in the file name storage area 14. To perform unnecessary processing (reading file name information from the directory entry area but discarding it without performing comparison processing and reading the next file name information). Since the file name information recorded in the head part of the file name information recording area in the directory entry area can be read out sequentially and compared with the temporary file name, the measurement data file already recorded in the memory card 7 can be obtained. A file name different from the file name of D2 can be specified in a shorter time.

  The configuration of the “measurement result recording device” and the specific procedure of the “measurement result recording method” are not limited to the configuration of the measurement result recording device 1 and the example of the measurement result recording method. For example, in the file name determination process 20 described above, the “first process (step 29)” is executed after the “second process (step 28)” is executed. The “second process” for storing the “file name” in the “file name storage area” is after the completion of the “first process” (specifically, after executing the above steps 29 and 30). It may be performed before step 24). Further, instead of step 28 in the file name determination process 20, not only a character string constituting the main body part in the file name but also a character string including an extension in the file name is stored in the file name storage area 14 (method). Can also be adopted. Further, the measurement result recording apparatus 1 including the measurement unit 2 has been described as an example, but the “measurement result recording apparatus” is configured only by the constituent elements other than the measurement unit 2 in the measurement result recording apparatus 1. The configuration in which the measurement data D1 in the above example is received from the measurement device as an external device configured similarly to the measurement unit 2 in the measurement result recording device 1 and the measurement data file D2 is recorded in the memory card 7 is adopted. You can also. Even when such a configuration is adopted, the same effects as those of the measurement result recording apparatus 1 can be obtained.
