2. Description of the Related Art In recent years, various portable terminal devices have been commercialized as data input terminal devices dedicated to on-site data collection, and have begun to be used in many fields. Such a portable terminal device for data collection includes a storage device for temporarily storing collected data, and is used for data processing of the collected data from the storage device of the portable terminal device. The input data is transferred to the storage device of the computer device, and the collected data is read into the computer device. Also, data transfer such as instruction data for the next data collection from the storage device of the computer device,
This is performed to the storage device of the portable terminal device. In such data transfer, it is necessary to transfer a large amount of data collected by the terminal device in a short time. Therefore, for example, the data transfer is performed between the portable terminal device and the computer device using a file transfer function. Read and write a large amount of data in a short time. For this reason, these portable terminal devices and computer devices are provided with a file transfer function for data transfer.

A data transfer interface for providing a file transfer function between a portable terminal device and a computer device of this type performs data communication with each other by a communication protocol utilizing a data transfer mechanism. The data transfer mechanism built in the portable terminal device as a standard equipment is used. Further, the data transfer mechanism here facilitates a physical connection operation between the portable terminal device and the computer device, and improves the usability of the user at the site. Many data transmission paths are electrically non-contact coupling forms such as optical coupling or electromagnetic induction coupling.

[0005] Such a failure during the data transfer has a structure in which the data transfer between the portable terminal device and the computer device is performed using the data transmission / reception function provided in the portable terminal device. In general, failure detection during data transfer can be dealt with only by a computer device program. For this reason, a transfer status history file for each terminal device is provided in the computer device, and recovery processing when a failure occurs is performed using the transfer status history file.

However, when a failure occurs during data transfer, the location of the failure is recorded in the file transfer history by the communication program on the transmitting side or the receiving side, and the part for starting retransmission after a series of data transfer processing is completed. Decision and re-transfer will be performed, but since the portable terminal device has a structure that can be easily removed, if the portable terminal device coupled with the computer device is replaced before re-transfer,
If the data transfer is not completely performed, or if the portable terminal device that needs to be re-transferred is combined with another computer device, it is not possible to recognize the re-transferred part or the other computer device For example, there is a problem that the recovery process for the occurrence of a failure during data transfer becomes complicated, such as the need for information exchange.

SUMMARY OF THE INVENTION The present invention has been made to solve such a problem, and an object of the present invention is to provide a terminal device with a built-in standard data transfer structure, without using an individual business program.

If the communication status display file is present, the data transfer system incorporates a processing function of displaying an abnormal state on the screen, displaying a message prompting a re-transfer operation, and then stopping.

[0013]

In the data transfer method according to the present invention, when performing data transfer using a file transfer function between a terminal device and a computer device capable of transferring a file by a data transfer mechanism, a file to be transferred is first identified. A communication status display file that records the information to be transferred is created, and the file transfer of the file of the created communication status display file is performed in the file transfer of the file entity of the transfer target file. Then, after the file transfer is completed, the data transfer state is detected using the transferred communication state display file. For example, after the file transfer is completed, the presence or absence of the transferred communication status display file is checked to determine whether or not a series of file transfer has been normally performed.

In the file transfer procedure when the file is transferred between the terminal device having the file transfer mechanism and the computer device, the communication status display file created for detecting the data transfer status includes: Transfer target file name or code corresponding to the file,
This is a file in which information such as a recovery method at the time of failure occurrence is recorded as, for example, one record, and this communication status display file is included in a part of the transfer target file to transfer the entire file. Thus, the presence or absence of a failure during the file transfer can be detected on the computer device side by confirming the presence or absence of the communication status display file performed after the file transfer. When the occurrence of a failure is detected, information relating to the method of recovering the file transfer failure, such as the name of the transfer target file to be recovered, is recorded in the communication status display file. make use of,
The recovery process can start immediately.

That is, in a data transfer system for transferring a file between a portable terminal device and a computer device using such a data transfer method, a communication status display file is created when a file is transferred. Then, the communication status display file is transmitted prior to the file transfer of the file entity of the transfer target file. Accordingly, the file recovery processing for the data transfer failure can be performed using the communication status display file, and thus the computer device can perform the file transfer without saving the transfer history of the file transfer. .

Here, in order to simplify the data transfer failure detection process and the failure recovery process, a file operation function is used between a terminal device and a computer device capable of transferring files by a data transfer mechanism. When performing data transfer, first create a communication status display file that records the file name information of the transfer target file, then perform file transfer of the created communication status display file, and then execute the file entity of the transfer target file. After the file transfer is completed, a request to delete the transferred communication status display file is transmitted. In this case, if normal data transfer can be performed, the communication status display file on the terminal device side should have been deleted. This can be done by checking the absence. When the absence of the communication status display file can be confirmed, it can be determined that the data transfer has been normally performed. Further, if the communication status display file remains as a file on the terminal device side, it is determined that a failure has occurred in data transfer, so the contents of the communication status display file are read out, for example, recorded in the communication status display file. Then, the terminal device deletes the file having the file name in the terminal device and performs a recovery process of retransmitting the file from the computer device.

In such a data transfer method, a file transfer is performed between a portable terminal device and a computer device, and data is collected by the portable terminal device. Is a function that checks the presence of a communication status display file at startup, displays an abnormal status on the screen if a communication status display file exists, displays a message prompting re-transfer operation, and then stops. Incorporate. Thereby, the user of the portable terminal device can check the file in the portable terminal device at the start of use of the device, and can know that the file transfer was incomplete at the time of the previous use. In addition, if the data collected by the portable terminal device is downloaded to the computer device at the time of file transfer, the data collected by the portable terminal device will not be forgotten to be input due to a user operation error.

When the data collection for the day is completed, the target customer information that the salesperson should visit is read from the disk device 2 and written to the storage device of the portable terminal device 5.

Next, the portable terminal device 5 will be described. FIG. 2 is an external plan view of the portable terminal device in a key operation state. FIG. 3 is a block diagram showing a configuration of a main part of the portable terminal device. This will be described with reference to FIGS.

As shown in FIG. 2, the main body structure of the portable terminal device 5 is such that a main body portion 21 of a so-called electronic notebook type folding type housing has a keyboard portion 22 having a large number of keys, and a dot matrix liquid crystal. The structure has a display unit 23. Although not shown, on the back of the main body 21,
A transmission / reception coupling unit that performs data communication by electromagnetic induction coupling is provided, and the transmission / reception coupling unit performs data communication with the terminal device interface adapter 4.

As shown in FIG. 3, the basic structure of the electric circuit of the portable terminal device 5 includes a control device unit 31, a display device unit 32, a storage device unit 33, and a keyboard unit 34. , A communication interface unit 35.

The communication interface unit 35 includes a transmission / reception coupling unit that performs data communication by electromagnetic induction coupling, and the transmission / reception coupling unit performs data communication with the terminal device interface adapter 4. The terminal device interface adapter 4 is connected to the computer device 1 via the data transfer interface cable 3 as described above.

The control program in the portable terminal device 5 for collecting customer information has a built-in file operation function as a standard function. As the file operation function, an inquiry about file existence confirmation, file creation, and file reading are provided. And file operation commands such as file deletion. Here, by using various commands of the file operation function, the file transfer process is performed in the computer device 1 without storing the state history of the file transfer status corresponding to each terminal device.

Therefore, when data is transferred between the portable terminal device 5 and the computer device 1 using the file transfer function, first, a communication status display file recording information for identifying the transfer target file is created. Then, in the file transfer of the file entity of the transfer target file, the file transfer of the created communication status display file is performed. Then, after the file transfer is completed, the data transfer state is detected using the transferred communication state display file.
Thus, for example, after the completion of the file transfer, by checking the presence or absence of the transferred communication status display file, it can be determined whether or not a series of file transfer has been normally performed.

Next, the communication status display file used here will be described. FIG. 4 is a diagram illustrating an example of the communication status display file. The communication status display file 40 here is, for example, as shown in FIG. 4, a file name 1, a file name 2, and a file name of a transfer target file (file 1, file 2, file 3,...) For performing file transfer. This is a file in which file names 3,... Are stored as one record.

The communication status display file 40 is used for detecting the data transfer status when data transfer is performed by using the file transfer function, and when the data transfer fails, recovery is performed afterwards. It is used as information for processing. For this reason, for example, it is sufficient if it can be instructed that data transfer is being performed, and if it is given instruction information for file recovery.
The communication status display file 40 is created only for the detection of the data communication status, and is included in the transfer target file in an extra manner and transmitted. Therefore, it is preferable that the file has a data capacity as small as possible.

For this reason, in this embodiment, as shown in FIG. 4, each file to be transferred has only one file name as one record. Further, as another example, the communication status display file created for detecting the data transfer status includes information such as a transfer target file name, a code corresponding to the file, and a recovery method when a failure occurs. It can be a file recorded as a record. In this case, if the name of the transfer target file to be recovered or the information on the recovery method of the file transfer failure is recorded as the communication status display file 40, if the occurrence of the failure is detected, the computer device 1 The side can immediately start the recovery process using the information of the communication status display file 40.

In the data transfer system for transferring files between the portable terminal device 5 and the computer device 1 using such a data transfer method, first, when performing file transfer, the communication status display file 40 is created. And
The communication status display file is sent prior to the file transfer of the file entity to be transferred. As a result, the file recovery process for the data transfer failure can be performed using the communication status display file. On the computer device side, in particular, it is possible to perform file transfer without saving the transfer history of the file transfer.

Next, the flow of data transfer processing of the entire system in the insurance customer information collecting system of the present embodiment will be described. FIG. 5 is a diagram for explaining the flow of processing when the data transfer processing is normally performed in the data transfer processing of the entire system. FIG. 6 is a diagram illustrating the case where an error occurs in the data transfer processing in the data transfer processing of the entire system. It is a figure explaining the flow of processing of. In the data transfer process, a portable terminal device (hereinafter, referred to as a terminal device) 5 capable of transferring files by a data transfer mechanism and a computer device in order to simplify a data transfer failure detection process and a failure recovery process. When data transfer is performed using the file operation function between the communication device 1 and the device 1, first, a file in which information on the file name of the transfer target file is recorded is created as the communication status display file 40 (FIG. 4). Next, file transfer of the created communication status display file 40 is performed,
Subsequently, file transfer of the file entity of the transfer target file is performed, and after completion of the file transfer, a request to delete the transferred communication status display file is transmitted. A case where data transfer is performed by this method will be described as an example.

According to this method, when the data transfer is normally performed, the communication status display file 40 on the terminal device 5 side is used.
Since the data transfer failure has been deleted, the data transfer failure can be detected by confirming the absence of the communication status display file 40 on the side of the terminal device 5 that has transferred the data transfer failure. Therefore, when the absence of the communication status display file 40 can be confirmed, it can be determined that the data transfer has been performed normally. If the communication status display file 40 is not deleted on the terminal device 5 side but remains, it is determined that a failure has occurred in data transfer.
The content of "0" is read, and for example, a file having the file name recorded in the communication status display file is deleted on the terminal device side, and then the computer device performs re-transfer processing for re-transfer.

First, with reference to FIG. 5, the flow of processing when the data transfer processing is performed normally will be described. In general, customer information for each sales representative will be displayed,
Since the batch transfer is performed from the host computer 6 to the computer device 1, the terminal device 5 is coupled to the computer device 1 after receiving the transfer at the computer device 1, and the terminal device 5 is connected between the computer device 1 and the terminal device 5. The processing is started when the data transfer path is established.

In the data transfer sequence diagram of FIG. 5, the computer device 1 collects customer information for performing data transfer from the host computer 6 to each terminal device 5 and collectively receives data (a) of a customer information file. Thereafter, data transfer processing of the customer information file data is performed for each terminal device 5. When the data transfer process is started, first, the computer 1 makes an inquiry (b) as to whether or not there is a communication status display file. On the other hand, when the terminal device 5 makes a response (c) indicating that there is no communication status display file, the terminal device 5 determines that the previous data transfer process has been completed normally. Start the data transfer process.

In this process, first, the customer information data collected by the terminal device 5 is read out to the computer device 1 side, so the computer device 1 makes a request (d) for reading customer information to the terminal device 5. . In contrast,
The terminal device 5 transmits (e) the contents of the customer information file. Next, the computer device 1 issues a request (f) for creating a communication status display file to the terminal device 5, and subsequently performs data transmission (g) of the communication status display file. As a result, on the terminal device 5 side, for example, there is a communication status display file that records only the file name of the transfer target file. Here, the existence of the communication status display file on the side of the terminal device 5 indicates that the terminal device 5
Means that the current state is a state in which data transfer has been started and the data transfer process is being performed.

Since the computer device 1 has read the data contents of the customer information file already collected from the terminal device 5 in the processing up to this point, the computer device 1 instructs the terminal device 5 to delete the read customer information file. Sends a report (h) to the host computer 6 indicating the completion of reading of the customer information of the terminal device, and then requests the terminal device 5 to delete the customer information file (i). 5 to wait for a response (j) to delete the customer information file.

Then, after the response (j) of the customer information file deletion is returned from the terminal device 5, the actual data of the customer information file to be transferred here is transferred. In this data transfer, a request (k) for creating a customer information file is made to the terminal device 5, and then data transmission (l) of the customer information file is sequentially performed. After successfully transmitting the entity data of this customer information file,
The terminal device 5 issues a communication status display file deletion request (m) to cancel the status of the data transfer being in the middle of data transfer, and the terminal device 5 responds to the communication device display file deletion request (m). Wait for n). After that, when the response (n) of the communication status display file deletion is returned from the terminal device 5, the computer device 1 determines that the data transfer of the entity data of the customer information file to be transferred here is normal. It is determined that the writing has been completed, and then the computer 1 reports to the host computer 6 that the terminal device has completed writing the customer information (o). Then, thereafter, the computer device 1 collectively transfers the customer information read from the terminal device 5 including the customer information read from the terminal device 5 to the host computer 6 in a batch ( Perform p).

Next, a description will be given, with reference to FIG. 6, of a processing flow in the case where retransfer is performed after a transfer failure occurs in the data transfer processing. In this case, in the initial state, the computer device 1 does not know to which portable terminal device a transfer failure has occurred in the previous data transfer process. The data transfer process is started in the same manner as the flow of the process in FIG. The customer information corresponding to each sales representative is batch-transferred from the host computer 6 to the computer 1 on the night before the day or the like, so that the customer 1 collectively receives the customer information file data in the computer 1 (a).
, The terminal device 5 is connected to the computer device 1 and the process is started by establishing the data transfer path.

In the data transfer sequence diagram of FIG. 6, the computer device 1 collects customer information for performing data transfer from the host computer 6 to each terminal device 5 and collectively receives data (a) of the customer information file. Thereafter, data transfer processing of the customer information file data is performed for each terminal device 5a. When the data transfer process is started, first, the computer 1 makes an inquiry (b) as to whether or not there is a communication status display file. On the other hand, if a transfer failure has occurred in the previous data transfer process, the communication status display file remains in the terminal device 5a without being deleted. q). When receiving the response (q) indicating the presence of the communication status display file from the terminal device 5a, the computer device 1 determines that the previous data transfer process has not been completed normally and performs its recovery process. Become.

In this recovery processing, the computer 1
Reads the communication status display file remaining in the terminal device 5a and performs a recovery process based on the contents of the communication status display file. For this reason, the computer device 1
First, a read request (r) of the communication status display file is made to the terminal device 5a, and the terminal device 5a waits for transmission of the contents of the communication status display file (s). On the contrary,
When the content of the communication status display file is transmitted (s) from the terminal device 5a, the computer device 1 then requests the deletion of the file having the name recorded in the communication status display file (record in the file) (t). And waits for a response (u) to delete the file requested to be deleted. Next, when there is a response from the terminal device 5a to delete the file having the name recorded in the communication status display file, the file transferred when a transfer failure has occurred in the previous data transfer process is deleted. Therefore, the computer 1 starts the process of retransmitting the customer information for the previous data transfer stored in the disk device 2. Such data transfer processing,
This is similar to the data transfer process described above.

That is, in the process of retransferring customer information to the terminal device 5a, a request for creating a customer information file is issued to the terminal device 5a in order to transfer the actual data of the customer information file to be transferred. v), and then the data transmission (w) of the customer information file is sequentially performed. Then, after the retransmission of the entity data of the customer information file is completed normally, a request (x) for deleting the communication status display file is made to the terminal device 5a,
Wait for a response (y) to delete the communication status display file from the terminal device 5a. After that, a response (y) of the communication status display file deletion is returned from the terminal device 5,
The computer device 1 determines that the data retransfer of the entity data of the customer information file to be transferred has been completed normally, and the computer device 1 instructs the host computer 6 of the terminal device. A completion report (z) of the customer information writing is performed. After that, as in the case where the normal data transfer process is performed, the computer device 1
The customer information read out from the terminal device including the customer information read out from the other terminal device 5 is collectively transferred to the host computer 6 (p).

As described above, in the insurance customer information collection system for transferring a file between the terminal device 5 and the computer device 1, when performing the file transfer, the communication status display file 40 is created and the transfer target file is created. Prior to the file transfer of the file entity, the communication status display file is transmitted, and the communication status display file 4 on the terminal device 5 side is transmitted.
The presence of 0 indicates that data transfer is in progress. Then, file transfer of the file entity of the transfer target file is performed, and after completion of the file transfer, a request to delete the transferred communication status display file is transmitted.

Therefore, the data transfer failure can be detected by confirming the absence of the communication status display file on the side of the transferred terminal device. In the presence state of the communication status display file, the file recovery processing related to the data transfer failure can be performed using the communication status display file. Transfer can be performed. For example, as described above, in the recovery process, the content of the communication status display file is read, the file having the file name recorded in the communication status display file is deleted on the terminal device side, and the data of the corresponding file is deleted from the computer device. Perform recovery processing to retransmit from the side.

Next, a description will be given of a processing program provided in the computer device 1 and the terminal device 5 when performing the above-described file transfer processing in the insurance customer information collecting system. FIG. 7 is a flowchart illustrating a processing flow of an example of a processing program provided in the computer device 1, and FIG. 8 is a flowchart illustrating a processing flow of an example of a processing program provided in the terminal device 5.

First, a processing flow of an example of a processing program provided in the computer device 1 will be described with reference to FIG. At the start of the transfer, it is normal that the communication status display file does not exist. If the communication status display file exists, it is determined that a failure has occurred in the previous transfer, and a recovery process is performed. In this case, since the transferred original file data remains in the computer device 1, in the recovery process, an inappropriate file at the time of occurrence of the failure is deleted, and the data transfer process is performed again. Therefore, the only recovery processing here is the processing of deleting the file corresponding to the file name recorded in the record of the communication status display file.

When the computer 1 starts the processing,
First, in step 60, an inquiry is made as to whether or not there is a communication status display file, and in the next step 61, it is determined whether or not there is no communication status display file. If there is no communication status display file, the previous data transfer processing has been completed normally, so the process proceeds to step 64, and processing relating to the current data transfer from step 64 is performed. If it is determined in step S61 that the communication status display file exists, the previous data transfer processing has been abnormally terminated. Therefore, the process proceeds to step S62, and processing relating to recovery processing of the previous data transfer processing is performed. I do. In the recovery process from step 62, the communication status display file is read, and then, in step 63, a process of deleting the file based on the file name recorded in the record in the communication status display file is performed. And
Proceed to step 70, and by the processing from step 70,
Perform data transfer processing of the customer information file to be transferred.

On the other hand, in the determination processing of step 61,
If it is determined that there is no communication status display file and it is confirmed that the previous data transfer process has been completed normally,
Proceeding to step 64, processing relating to the current data transfer is performed. In this process, first, in step 64, a customer information file is read. By the reading process of this customer information file, only updated customer information reflecting the result of patrol of the customers is collected. Then, in step 65, it is determined whether or not the reading process has been completed normally. If it is not determined that the process has been completed normally, the process for the terminal device ends as an abnormal end.

If it is determined in step 65 that the reading process has been completed normally, then the terminal device indicates that the customer information file is being created. Create.
For this reason, in the next step 66, a communication status display file creation process is performed, and in the next step 67, it is determined whether or not the communication status display file creation process has ended normally. Confirm that it was created. If the communication status display file has not been created normally, the processing for the terminal device ends as an abnormal end.

In the determination process of step 67, if it is confirmed that the communication status display file has been created normally, then in step 68, the computer 1
Notifies the host computer 6 of the completion of the customer information reading process performed in the previous steps 64 and 65. Then, in the next step 69, a process for deleting the customer information file is performed on the terminal device 5. As a result, the process related to the previous customer information collection in the terminal device 5 has been completed, and next, the process of writing the customer information to be circulated to be collected this time into the terminal device is started. For this reason, in the next step 70, a process of creating a customer information file is performed, and data transfer is performed. Then, in the next step 71, it is determined whether or not the customer information file has been created normally. If the customer information file has not been created normally, the processing for the terminal device is terminated as abnormal termination. Also,
In the determination process of step 71, if it is confirmed that the customer information file creation has been normally performed, the series of data transfer processes here are all normally completed. Perform processing to delete the status display file.

That is, in the next step 72, a process for deleting the communication status display file created in the terminal device is performed to indicate that the customer information file is being created at the beginning of the process. And the next step 7
3, confirms that the process of deleting the communication status display file has been completed normally, and in the next step 74, the computer 1 reports to the host computer 6 that the process of writing the customer information to the terminal has been completed. Do the processing,
A series of processing ends. If it is determined in the determination process of step 73 that the process of deleting the communication status display file has not been performed normally, the process for the terminal device ends as an abnormal end.

Next, the processing flow of the processing program provided in the terminal device 5 will be described. In the insurance customer information collection system, the terminal device checks the presence or absence of the communication status display file at the time of startup, and if the communication status display file is present, displays an abnormal state on the screen and prompts a re-transfer operation. Built-in processing function to stop after displaying message. As a result, the user of the terminal device can know that the customer information collected in the previous tour has not yet been input to the computer side at the terminal device, and the incomplete operation of the system due to a user operation error. Can be prevented.

Referring to FIG. 8, the processing flow for starting the processing program of the terminal device 5 will be described. When the processing program of the terminal device 5 is turned on and the start of the business program is instructed, first the step At 75, it is confirmed whether or not there is a communication status display file, and then, at the next determination process of step 76, it is determined whether or not there is no communication status display file. In this determination, if it is not determined that there is no communication status display file, the terminal device is in a state where the customer information collected in the previous patrol has not yet been input to the computer, or Therefore, it is determined that the customer information to be circulated is not input from the computer device side, so that in the next process of step 78, a message indicating that the file transfer has failed is displayed on the display device. Then, subsequently, in the next step 79, a process for displaying a message notifying that the operation for file transfer is performed again is performed on the display device, and the process ends.

In the determination processing of step 76,
If it can be determined that the communication status display file is absent, the terminal device informs the computer that the customer information collected in the previous patrol has been normally input to the computer, and that the customer who is scheduled to patrol normally for the current customer information collection Since the information has been input from the computer device side, the process directly proceeds to the next step 77, where the normal startup process of the business program is performed, and the process is terminated.

As described above, in the business program of the terminal device, the presence or absence of the communication status display file is checked at the time of startup. If the communication status display file exists, the normal business process is started. By incorporating a processing function of judging, displaying a warning message and stopping the program, the user of the terminal device can check the file in the terminal device at the start of use of the terminal device, You can know that the file transfer was incomplete. In addition, as described in the above-described processing flow of a series of data transfer, if the collected data is downloaded to the computer device at the time of file transfer, the collected data at the terminal device may be lost due to a user operation error. There is no forgetting to enter.

The essential points for implementing the data transfer method according to the embodiment of the present invention described above are summarized as follows. That is, if the state of the file transfer is to be saved on the computer device side, the state must be stored for each terminal device. If the state of the file transfer is to be saved on the terminal device side, the protocol with the computer device must be stored. However, if only the file transfer function built into the terminal device is used, the existence of any file, creation of a file, reading of a file, and erasing of a file can be performed by a request from a computer device. . For this reason, in this embodiment, when the program operating on the computer device side initiates the file transfer, it requests the creation of a file (communication status display file) with a specific file name indicating that the file is being transferred. Is displayed, and when the file transfer is completed successfully,
A request is made to delete the file. Thus, if the file exists when the file is transferred, it can be determined that a failure has occurred during the file transfer, and thus the occurrence of the file failure can be detected independently of the business program on the terminal device side.

If the name of the file to be transferred is recorded in this file (communication status display file), when the file is transferred from the computer, if the file exists and it is determined that a failure has occurred, Thus, the file name recorded in the file can be recognized as a file in which a failure has occurred, and a recovery process can be performed. Even if the file to be transferred is changed by modifying the file transfer program, using the contents of the file does not affect the program. In addition, when the business program on the terminal device determines the existence of this file at the time of startup, if the file exists, it can be determined that a file that has not been transferred is present, and a message prompting re-transfer is issued. By displaying, it is possible to prevent operational errors in operation.

As described above, in the detection of the data transfer state, the communication state at the previous transfer can be known by confirming the presence or absence of the communication state display file when performing the file transfer. Since the file can be created by a file operation function which is built in the terminal device as a standard, a failure in the file transfer can be detected without depending on the business program of the terminal device. In addition, since the communication status display file here uses only the presence or absence of the file for failure detection, the content of the communication status display file does not matter. Therefore, depending on the content recorded as the communication status display file, it is possible to not only detect the occurrence of a failure, but also record the name of the file to be recovered and the recovery method, and use it as information for subsequent processing. .

[0058]

As described above, according to the data transfer method of the present invention, a data transfer failure can be detected without relying on the communication procedure with the business program on the terminal device side, and the failure recovery during file transfer can be recovered. It can be easily performed only by the program processing procedure on the computer device side. Furthermore, the business program detects a file transfer error on the terminal device side, and can display a message requesting retransfer without operating in an abnormal state, thereby preventing trouble during operation.
