This is a problem especially when the screen of the transfer destination device is small and difficult to operate.

  Further, when data is moved, it is necessary to perform a troublesome operation of deleting the data in the transfer source device after copying the data to the transfer destination device. In addition, since the transfer data remains in the storage medium, a troublesome operation of deleting the data on the storage medium is necessary. In the case of highly confidential data, it is not preferable to leave the data in a plurality of locations.

  In addition, since there is no information on whether the file has been copied to the transfer destination device in the transfer source device, there is a problem that it is difficult to know which file has already been copied to the transfer destination device. This is a problem because the files cannot be directly compared, especially when the transfer source device and the transfer destination device are in different locations.

  The main object of the present invention is to solve the above-described problems, to reduce the number of operations at the transfer destination device, and to recognize whether the user has already copied the file at the transfer source device. The main purpose is to automatically delete unnecessary files after transfer.

  FIG. 5 shows the overall operation sequence of the first embodiment.

  First, an operation (S101 to S105) in which the transfer source device 2 writes a data file to be moved to the storage medium 1 will be described with reference to FIG.

  The storage medium 1 and the transfer source device 2 are connected (S101, storage medium connection step). In the connected state, the user operates the transfer source display operation unit 24 to instruct to transfer the data file to the transfer destination device 3. (S102).

In the case of “move”, the data file is deleted from the transfer source device 2.

Reference numeral 105 denotes an execution button for instructing execution of writing of the data file to the storage medium 1,
Reference numeral 106 denotes a cancel button for instructing cancel.

  When the execution button 105 is operated by the user via the transfer source display operation unit 24 (S102), the transfer source control unit 23 reads the data file designated by the transfer target data file name field 101 from the transfer source storage unit 21. Then, the copy is written to the storage medium 1 via the transfer source storage medium interface unit 22 (S103). Further, a transfer information file (transfer related information) is generated, and the generated transfer information file is written to the storage medium 1 (S104, transfer related information generation step, write step).

FIG. 8 shows an example of a directory structure in the storage medium 1 after the writing process is performed. In this example, a directory named “FILELANSFER” is at the top,
The data file “DAT00001.dat” and the transfer information file “INF00001.inf” are stored therein.

  In the first embodiment, the “FIELTRANSFER” directory is a directory in which data files and transfer information files are stored.

  The data file “DAT00001.dat” is a copy of the file specified by the transfer target data file name field 101, and this file name is named so as not to be duplicated with other files in the “FILETRANSFER” directory. .

  The transfer information file “INF00001.inf” is created in accordance with the transfer conditions entered on the screen of FIG. 7, and this file name has an extension “in order to avoid duplication with other files in the“ FIELTRANSFER ”directory. .Inf ".

  FIG. 9 shows an example of the transfer information file.

  The COMMAND item 201 is a processing instruction for instructing a transfer form. In this specification, two types of transfer, “copy” and “move”, are assumed as transfer modes. When the file is “copied” from the transfer source device 2 to the transfer destination device 3 by the input of the operation type field 104 in FIG. 7, the value of “COPY” is taken, and when the file is moved, “MOVE” is taken. In this example, movement (“MOVE”) is shown.

  A SOURCE DEVICE item 202 indicates the device ID of the transfer source device 2, and is a value stored in the transfer source device ID section 25.

  The SOURCE FILE item 203 is an identifier of data to be transferred, indicates the file name of the data file in the transfer source device 2, and is a value input to the transfer target data file name field 101 in FIG.

  The TRANSFERFILE item 203 indicates the file name of the data file copied to the storage medium 1, and is “DAT00001.dat” in this example.

  The DESTINATION DEVICE item 205 indicates the device ID of the transfer destination device 3, and is a value input to the transfer destination device ID field 102 in FIG.

  The DESTINATIONFILE item 206 indicates a file name in which the data file is stored in the transfer destination device 3 and is a value input in the transfer destination file name field 103 in FIG. The DESTINATIONFILE item 206 indicates the storage destination (storage location) of the transfer target data in the transfer destination device 3, and is an example of the storage location instruction.

  When the writing of the data file and the transfer information file from the transfer source device 2 to the storage medium 1 is completed, the transfer source device 2 and the storage medium 1 are disconnected (S105).

  Next, an operation (S201 to S207) of writing a data file from the storage medium 1 to the transfer destination device 3 will be described with reference to FIG.

  The storage medium 1 and the transfer destination device 3 are connected (S201, storage medium connection step), the transfer destination storage medium interface unit 32 detects the connection, and the transfer destination device 3 automatically detects “FILETRANSFER” in the storage medium 1. The transfer information file in the directory is read (S202, read step). The transfer information file is identified by its extension (“.inf”).

  Then, the transfer destination control unit 33 checks whether or not the value (device ID) of the DESTINATION DEVICE item in the transfer information file matches the device ID stored in the transfer destination device ID unit 35 of the transfer destination device 3 (S203). Analysis instruction step).

  If they do not match (NG), the transfer destination apparatus 3 is not instructed to transfer, and the subsequent processes of S204 to S206 are not performed.

  In this example, since the value “BB98765” of the DESTINATION DEVICE item of the transfer information file and the value “BB98765” of the transfer destination device ID part 35 of the transfer destination device 3 match, the transfer destination control unit 33 sets the data file to be transferred. Is instructed to proceed to S204.

  In the data file copy process (S204), the data file in the storage medium 1 specified in the TRANSFERFILE item of the transfer information file (in this example, “DAT00001.dat”) is used as the value of the DESTINATIONFILE item (in this example, “C: (¥ Home ¥ BBB ¥ data1.data ”) is copied and stored in the transfer destination storage unit 31 as a file name (data storage step).

  Next, the transfer information file on the storage medium 1 is updated (S205). The updated transfer information file in this example is shown in FIG.

  In the example of FIG. 11, a RESULT item indicating the transfer result is added to the transfer information file (FIG. 9) written by the transfer source device 2. In this example, the data file is copied to the transfer destination device 3. “SUCCESS” indicates that the processing has been successful. This RESULT item indicates the success or failure of storage of the data file to be transferred in the transfer destination device 3, and corresponds to storage success / failure information.

  Next, the data file that has been copied from the storage medium 1 to the transfer destination apparatus 3 and is no longer needed is deleted from the storage medium 1 (S206).

  Then, the storage medium 1 and the transfer destination device 3 are disconnected (S207).

  Next, an operation (S301 to S308) of reading the transfer result added to the transfer information file of the storage medium 1 by the transfer source device 2 will be described with reference to FIG.

  When the storage medium 1 is connected to the transfer source device 2 (S301), the transfer source storage medium interface unit 22 of the transfer source device 2 detects this, and the transfer source device 2 automatically detects the “FILETRANSFER” directory in the storage medium 1. The transfer information file is read out (S302).

  Then, the transfer source control unit 23 checks the SOURCE DEVICE item 202 of the transfer information file (S303).

  If the value (device ID) of the SOURCE DEVICE item 202 does not match the value of the transfer source device ID section 25 of the transfer source device 2, the subsequent processing from S304 to S307 is not performed. If they match, the process proceeds to the next RESULT item confirmation process (S304).

  In this example, since the value “AA12345” of the SOURCEDEVICE item 202 of the transfer information file matches the value “AA12345” of the transfer source device ID section 25 of the transfer source device 2, the process proceeds to the RESULT item confirmation process.

  Next, the transfer source control unit 23 checks the RESULT item 207 of the transfer information file (S304), and when the RESULT item is not “SUCCESS”, the subsequent processing from S305 to S307 is not performed.

  If the RESULT item is “SUCCESS”, since the data transfer in the transfer destination device 3 has succeeded, the COMMAND item of the transfer information file is checked next (S305).

  When the COMMAND item is “MOVE”, this means that the data file is moved from the transfer source device 2 to the transfer destination device 3, so that the SOURCE FILE item 203 is indicated from the transfer source storage unit 21 in the transfer source device 2. (In this case, “SOURCEFILE = C: ¥ Home ¥ AAA ¥ data1.dat”) is deleted (S306).

  When the COMMAND item is “COPY”, the process of deleting the file from the transfer source device 2 is not performed.

  Then, the storage medium 1 and the transfer source device 2 are disconnected (S308).

  As described above, in the data transfer system according to the present embodiment, the transfer source device stores information related to the transfer data together with the transfer data in the storage medium, and the transfer destination device reads the information related to the transfer data and performs the transfer process. It is characterized by.

  In addition, the transfer source device stores a storage destination in the transfer destination device together with the transfer data in a storage medium, and the transfer destination device stores the data in the storage destination.

  Furthermore, the transfer source device stores the identifier of the transfer destination device together with the transfer data in a storage medium, and the transfer destination device checks the identifier to determine whether or not to perform transfer processing.

  In addition, the transfer destination device deletes the transfer data on the storage medium after reading the transfer data from the storage medium.

  Further, the transfer destination device stores the processing result (copy to the transfer destination device) for the transfer data on a storage medium.

  Further, the transfer source apparatus reads a processing result in the transfer destination apparatus from a storage medium, and deletes transfer data on the transfer source apparatus when the processing result in the transfer destination apparatus is successful.

  Further, the transfer source apparatus checks the operation mode recorded on the storage medium, and deletes the transfer data in the case of “move”.

  Further, the transfer source device stores the identifier of the transfer source device together with the transfer data in a storage medium, and the transfer destination device checks the identifier to determine whether to perform processing according to the transfer result. To do.

  In addition, the transfer source device records the identifier (file name) of the transfer data on the transfer source device on the storage medium, and corresponds to the identifier of the transfer data when the storage medium is connected to the transfer source device. The data to be deleted is deleted on the transfer source device.

  As described above, according to the first embodiment, the transfer information file including the transfer destination file name in the transfer destination device 3 is stored in the storage medium by the transfer source device 2 and stored in the transfer destination device 3. Since transfer processing is performed according to the transfer information file when the medium 1 is connected, complicated copy operations such as designation of a file name in the storage medium 1 and designation of a file name in the transfer destination device 3 are performed by the transfer destination device. The user does not need to do it.

  In addition, since the transfer destination device checks the device ID of the transfer destination device described in the transfer information file and confirms that it is a data file for its own device, it may transfer to another terminal by mistake. There is no.

Further, after the data file is copied from the storage medium 1 to the transfer destination device 3, the data file on the storage medium 1 is automatically deleted. Is not squeezed.
In addition, it is not necessary for the user to delete the data file on the storage medium 1.
Further, when the file is confidential information, security is enhanced by not leaving an unnecessary file.

Further, after the data file is copied from the storage medium 1 to the transfer destination device 3, the data file on the storage medium 1 is automatically deleted. Is not squeezed.
In addition, it is not necessary for the user to delete the data file on the storage medium 1.
Further, when the file is confidential information, security is enhanced by not leaving an unnecessary file.

  In the case of moving the data file, the result of copying the data file from the storage medium 1 to the transfer destination device 3 is recorded in the transfer information file on the storage medium 1, and the result recorded in the transfer information file. The data file is automatically deleted from the transfer source device 2 only when the data transfer is successful.

  Therefore, even if the user does not perform a special operation on the transfer source device 2, the data file of the movement source is automatically deleted.

  Further, since the data file of the movement source is deleted from the transfer source apparatus 2 only after the copy to the transfer destination apparatus 3 is successful, the storage medium storing the data file before copying the data file to the transfer destination apparatus 3 There is no worry that the data file in the transfer source device 2 is lost when 1 is lost.

Although the case where the data file is “moved” from the transfer source device 2 to the transfer destination device 3 has been described here, “copy” can be performed in the same manner. The difference in processing is as follows.
1. “Copy” is selected in the operation type field 104 of FIG.
2. When writing to the storage medium 1 by the transfer source device (S104), the value of the COMMAND item 201 of the transfer information file is set to “COPY”.
3. When the value of the COMMAND item 201 of the transfer information file is checked by the transfer source device (S305), since it is not “MOVE”, the process of deleting the data file in the transfer source device 2 (S306) is not performed.

  Here, the transfer source device 2 and the transfer destination device 3 have been described as separate devices, but a device in which both functions are integrated may be used.

  Here, the case of a file as data to be transferred has been described, but the same applies to data that is not a file.

  Also, the contents of the transfer information file need not necessarily be recorded in the file, and can be the same in other recording methods as long as they are recorded in some form in the storage medium 1.

  In the case of highly confidential data, the confidentiality may be ensured by encrypting the data.

  Also, here, it has been described that the processing is automatically started when a storage medium is connected to the transfer source device 2 or the transfer destination device 3, but after confirming with the user such as "Do you want to process?" Subsequent processing may be performed.

  Further, here, the value in the transfer information file recorded in the storage medium 1 has been described as being read out and compared to the transfer source device 2 or the transfer destination device 3, but the comparison value is stored using an IC card or the like. It may be sent to the medium 1 and a comparison process or the like may be performed in the storage medium 1.

Embodiment 2. FIG.
In the first embodiment, a method for moving a data file from a transfer source device to a transfer destination device using a transfer information file has been described. In the second embodiment, a data file is transferred from a transfer source device to a transfer destination device. An embodiment is shown in which when copying, the record remains in the transfer source device.

  The configuration of the data transfer system in the second embodiment is the same as that of FIG. 1 of the first embodiment, and the configurations of the storage medium 1, the transfer source device 2, and the transfer destination device 3 are also the same, and the description thereof is omitted (FIG. 2 to 4).

  In the second embodiment, data is “copied” from the transfer source device 2 to the transfer destination device 3. At this time, a method for recording the data copy processing status in the transfer source device 2 will be described below.

  FIG. 13 shows the overall operation sequence of the second embodiment.

  First, an operation (S101 to S105) in which the transfer source device 2 writes a data file to be moved to the storage medium 1 will be described with reference to FIG.

  This operation is almost the same as the operation of writing the data file of the transfer source device 2 described in the first embodiment to the storage medium 1 (FIG. 6), but the file transfer operation by the user (S102) and the storage of the transfer information file. The internal operation of writing to the medium (S104) is partially different, and a transfer state recording process (S401) is added after writing the transfer information file to the storage medium (S104).

  Hereinafter, these different points will be described.

  FIG. 15 shows an example of a screen displayed on the transfer source display operation unit 24 of the file transfer operation (S102) by the user.

  Although it is almost the same as in FIG. 7, in the second embodiment, “copy” is entered in the operation type field 104 in order to “copy” the data file from the transfer source device 2 to the transfer destination device 3.

  Thereafter, after the “execute” button 105 is operated by the user (S102), the operation of writing the data file to the storage medium 1 (S103) and the operation of writing the transfer information file to the storage medium 1 (S104) are described in the first embodiment. However, the transfer information file is partially different.

  FIG. 16 shows an example of the transfer information file in the second embodiment.

  Similar to the example of the transfer information file described in the first embodiment (FIG. 9), in this second embodiment, the data file is “copied” from the transfer source device 2 to the transfer destination device 3, and therefore the COMMAND item 201 is used. The value of “COPY” is “COPY”.

  Next, a data transfer state management file in which the state of data transfer from the transfer source device 2 to the transfer destination device is recorded is recorded in a directory with transfer target data in the transfer source storage unit 21 of the transfer source device 2 (S401). . This directory structure is shown in FIG.

  In FIG. 17, the “transfer.inf” file is a data transfer state management file, and this data transfer state management file is placed in the same directory as the data file to be transferred (in this example, “data1.dat”) Manage the transfer status for each file.

  FIG. 18 shows an example of a data transfer state management file in which the data transfer state is recorded.

  In FIG. 18, a FILENAME item 301, a STATUS item 302, and a DESTINATION DEVICE item 303 form a set, and when other files in the directory are described, they are recorded separated by blank lines.

  A FILENAME item 301 indicates the name of the data file to be transferred.

  In the second embodiment, since the data transfer state management file is intended only for files in the directory in which it is placed, the directory name is omitted.

  The STATUS item 302 indicates the current data transfer state as the transfer status. In step S401, the data file is written to the storage medium 1 for transfer, and is “COPYING” because it is in the process of “copying” to the transfer destination device 3.

  The DESTINATION DEVICE item 303 indicates the device ID of the data file transfer destination device 3.

  Thus, by recording the data transfer status in the data transfer status management file during the data transfer processing, it becomes possible for the transfer source device 2 to grasp the status of the data transfer processing.

  FIG. 19 shows an example of a screen for displaying the file in the transfer source storage unit 21 together with the data transfer state.

  In FIG. 19, a directory name field 401 is a field for displaying a directory name of a file displayed in the file name list 402.

  The file name list 402 is a table that displays files in the directory indicated by the directory name field 401.

  A file name column 403 displays file names in the directory.

  The status column 404 is a column for displaying the status of the data transfer. This is a search for the FILENAME item 301 that matches the file name in the file name column 403 from the data transfer status management file (transfer.inf) file, and the matched FILENAME item. The value of the STATUS item 302 corresponding to 301 is displayed.

  The transfer destination column 405 is a column that displays the data transfer destination device. This is a file transfer state management file (transfer.inf) file that is searched for the FILENAME item 301 that matches the file name in the file name column 403, and the matched FILENAME. The value of the DESTINATION DEVICE item 303 corresponding to the item 301 is displayed.

  In this example, it is displayed that the “data1.dat” file is “copying” to the transfer destination device “BB98765”.

  Thus, by recording the state of the data transfer process in the data transfer state management file, when performing data transfer via the storage medium 1, the transfer source device 2 can grasp the state of data transfer. it can.

  Next, since the operation of connecting the storage medium 1 to the transfer destination device 3 and writing the data file to the transfer destination device 3 is the same as that of the first embodiment (FIG. 10, S201 to S207), the description is omitted. An example of the transfer information file written to the result storage medium 1 is shown in FIG.

  In FIG. 20, the value of the RESULT item is added as “SUCCESS” in the transfer destination apparatus with respect to FIG. 16, and this operation is the same as that of the first embodiment.

  This operation is almost the same as the operation of connecting the storage medium 1 described in the first embodiment to the transfer source device 2 again and the transfer source device 2 reads the transfer result from the storage medium 1 (FIG. 12). Since this is a “copy” operation, the determination in S305 is different, the process of deleting the data file in the transfer source apparatus (S306) is not performed, and the transfer status recording process (S402) is added. Will be described.

  In the process of checking the COMMAND item of the transfer information file (S305), since the COMMAND item 201 is “COPY” as shown in the example of FIG. 21 in the second embodiment, the process branches to the transfer state recording process (S402).

  In this transfer state recording process (S402), the transfer state management file ("transfer.inf") in the transfer source storage unit 21 is updated, and the STATUS item of the data transfer state management file corresponding to the SOURCEFILE item 202 of the transfer information file. Is changed to “COPYED”.

  The updated transfer state management file is shown in FIG.

  In FIG. 18, the value of the STATUS item 302 is “COPYED” as the transfer status.

  FIG. 23 shows an example of a screen when the file in the transfer source storage unit 21 is displayed together with the data transfer state in the state of the transfer state management file in FIG.

  In FIG. 19, the value 404 in the status column corresponding to the file name “data1.dat” is “COPYED”.

  In this example, it is displayed that the “data1.dat” file is “copied” to the transfer destination device “BB98765”.

  As described above, in the data transfer system according to the present embodiment, the transfer source device writes data to the storage medium for transfer on the transfer source device, and indicates that the data is being transferred to the transfer source storage unit. It is characterized by recording.

  Further, the transfer source device reads the processing result in the transfer destination device from the storage medium and records that “data transfer has been completed” in the transfer source storage unit according to the processing result.

  As described above, according to the second embodiment, the file to be transferred by the transfer source device 2 to the storage medium 1 is written, and the file is “copying” in the transfer source storage unit 21 of the transfer source device 2. Is recorded on the transfer source device 2, the file being “copied” can be identified. Further, since the transfer source device 2 records that the transferred file is “copied” based on the result of the transfer information file recorded in the storage medium 1, the “copied” file is recorded on the transfer source device 2. Can be identified. Since the “copied” file can be identified, an operation such as deleting only the “copied” file by a later user operation becomes easy.

  In the second embodiment, the case of the “copy” operation of the file has been described. However, in the case of the “move” operation, a state such as “moving” or “moved” may be recorded.

  In the second embodiment, it has been described that two stages of information “copied” and “copied” are recorded in the data transfer status management file.
