[0002]

2. Description of the Related Art Conventionally, data has been transferred to a PC (Personal Compute).
As a method of exchanging data between r), a method of writing data in an e-mail and transmitting / receiving the data is known. When e-mail is sent and received by commonly used mail software, the sending PC indicates header information, an attached file header, an encoded attached file, and the end of the mail in the mail body input by the user. The mail data to which a period or the like is added is transmitted.

Next, the CPU 31 determines whether or not the data processing mail transmission flag 34d of the RAM 34 is set to "1" (step S2). If the flag is set to "1", that is, the mail instructing the data processing is performed. If the data has been transmitted and the mail data including the processing result for the mail data has not been received, the process proceeds to step S3, and if not set to "1", the process proceeds to step S4. Transition.

In step S 3, the CPU 31 determines from the previous connection with the host device 4 as the provider that the RA
It is determined whether or not the time set in the predetermined time memory 34c of M34 has elapsed (step S3). If the time set in the predetermined time memory 34c has elapsed, the process proceeds to step S13, and if not, the process proceeds to step S4.

In step S4, it is determined whether or not a key input for selecting a mode has been made from the input device 32.
If there is a key input, it is determined whether the mode selected by the key input is mail reception, mail transmission, or other (step S5). It returns to step S2.

If it is determined in step S5 that the selected mode is mail reception, the process proceeds to step S1.
The process proceeds to step S3, and if it is determined that the selected mode is mail transmission, the process proceeds to step S6, and if it is determined that another mode is selected, the process returns to step S2.

The CPU 31 executes a mail creation process (FIG. 11) described later in step S6. And
It is determined whether or not the mail data created in step S6 has been determined (step S7). If the mail data has been determined, a sending-side mail shaping process (FIG. 13) for shaping the mail into a predetermined format is executed (FIG. 13). Step S8) If not determined, cancel the mail data created in step S6 and return to step S2.

After executing the transmission side mail shaping process in step S8, the CPU 31 connects to the host device 4 which is the mail server of the provider via the public communication line 2 (step S9).

Then, the connection with the host device 4 is disconnected (step S11), and it is determined whether or not the processing is completed (step S12). If it is finished, the process is finished as it is, and if not, the process returns to step S2.

If the mail receiving mode is selected in step S5, or if it is determined in step S3 that the predetermined time set in the memory 34c has elapsed, the CPU 31 determines whether the host is a mail server of the provider. It is connected to the device 4 via the public communication line 2 (step S13), and it is determined whether or not there is a mail addressed to the mobile terminal device 3 (step S14).
The mail is received by the transmission control unit 35 and is stored in the RAM.
The mail is stored and stored in the mail reception data memory 34a (step S15). If there is no mail, the process proceeds to step S21.

In step S15, when the received mail is stored in mail reception data memory 34a,
31 disconnects the connection with the host device 4 as the provider (step S16), and stores the mail reception data memory 34a.
Searches the header part of the mail stored in, and depending on the presence or absence of the processing result extension header, whether the mail is a general mail not including the processing result of data processing, or
It is determined whether the mail is a processing target mail including data such as a processing result (step S17).

If it is determined in step S17 that the received mail is a general mail, the mail reception data memory 34a
Is displayed on the display device 33 (step S20), and the process proceeds to step S21. If it is determined that the received mail is a processing target mail, a processing result mail analysis process (FIG. 12) described later is executed on the received mail (step S18), and the processing result included in the received mail is displayed on the display device 33.

In step S86, it is determined whether or not general text is included in the created mail data. If there is no general body text, the sending-side mail shaping process ends, and the process moves to the next process (step S9) in the sending-side mail sending / receiving process (FIG. 10). If there is a general body text, it is determined whether or not a normal header has already been added, and whether or not there is (step S8).
7). If there is a normal header, step S
The process proceeds to 89, and if there is no normal header, a normal header is added (step S88), and the header and the body text are formatted according to a predetermined format (step S89).
After terminating the process, the process proceeds to the next process (step S9) in the sending / receiving mail transmission / reception process (FIG. 10).

Next, mail transmission / reception processing executed by the CPU 61 of the terminal device 6 will be described with reference to the flowchart shown in FIG.

First, the CPU 61 displays an operation screen or the like corresponding to the mail transmission / reception processing program on the display device 63 in accordance with an input instruction from the input device 62 (step S3).
1). Next, the CPU 61 determines whether or not a predetermined time set in the memory 64c for a predetermined time in the RAM 64 has elapsed since the previous connection with the server 5 (step S).
32). If the predetermined time set in the predetermined time memory 64c has elapsed, the process proceeds to step S43, and if not, the process proceeds to step S33.

In step S33, it is determined whether or not a key input for selecting a mode has been made from the input device 62, and if a key input has been made, whether the mode selected by the key input is mail reception. It is determined whether the transmission is a mail transmission or other (step S34). If there is no key input, the process returns to step S32.

If it is determined in step S34 that the selected mode is mail reception, the process proceeds to step S34.
The process moves to step S43, and if it is determined that the selected mode is mail transmission, the process proceeds to step S36. If it is determined that another mode has been selected, another process corresponding to the selected mode is performed. (Step S3
5) Return to step S32.

In step S36, the mail creation processing (FIG. 11) is executed. Then, the CPU 61 determines whether or not the created mail data is determined in step S36 (step S37). If determined, the process proceeds to step S38. If not determined, the process proceeds to step S36. The created mail data is canceled, and the process returns to step S32.

The CPU 61 determines in step S38
Mail shaping process for shaping mail into a predetermined format (Fig. 1
Execute 7). The transmission control unit 66 connects to the server 5 (step S39), transmits the mail data shaped in step S38, and stores the transmitted mail data in the mail transmission data memory 64b of the RAM 64.
And store it as mail transmission data (step S
40), and disconnects from the server 5 (step S4).
1), it is determined whether or not the processing is completed (step S4)
2). If it is finished, the process ends. If not, the process returns to step S32.

If the mail receiving mode is selected in step S34, or if it is determined in step S32 that the time set in the memory 64c has elapsed, the CPU 61 connects to the server 5 (step S43). ), It is determined whether or not there is a mail addressed to the terminal device 6 in the server 5 (step S44). If there is no mail, the process proceeds to step S53. If there is a mail, a mail reception / deletion selection process (FIG. 19), which will be described later, is executed (step S45).
Only the selected mail is received, the received mail data is stored and stored in the mail reception data memory 64a (step S46), and the connection with the server 5 is disconnected (step S46).
47).

Next, the CPU 61 searches the header of the mail data stored in the mail reception data memory 64a in step S46, and determines whether or not the mail data does not include a data processing instruction according to the presence or absence of the data processing extension header. Or a mail to be processed including a data processing instruction (step S).
48). If the received mail is a general mail, the received mail is displayed on the display device 63 (step S52).
Go to 53.

If the mail is a processing target mail, a received mail analyzing process (FIG. 15) described later is executed (step S4).
9), the processing result transmission processing (FIG. 18) is executed (step S50), and the mail data including the transmitted processing result and the processing result are stored and stored as mail transmission data in the mail transmission data memory 64b (step S51). ), And proceed to step S53. In the step S53, it is determined whether or not the processing is completed.
The process proceeds to step S2, and if it is completed, the process ends.

Next, the received mail analysis processing executed by the CPU 61 of the terminal device 6 (FIG. 14; step S49)
Will be described based on the flowchart shown in FIG.

When it is determined that the received mail is the mail to be processed (FIG. 14; step S48; mail to be processed), the CPU 61 divides the mail data into a header portion and a body (step S491), and transmits the data from the header portion. The original information is taken out (step S492). Then, based on the extracted information of the sender, the mail address of the sender is RA.
It is determined whether or not the address is the specific address set in the source specific address 64f of M64 (step S493).

If it is determined in step S493 that the source address is not set to the source specific address 64f, mail data with the unprocessable message as the text and the source as the reply destination is automatically created ( (Step S499), the received mail analysis processing is ended, and the routine goes to Step S38 in the mail transmission / reception processing (FIG. 14).

If it is determined in step S493 that the source address is the specific address set in the source specific address 64f, the processing target is extracted from the header (step S494), and data processing is performed from the text. Are extracted (step S495), the program corresponding to the extracted key item is activated by referring to the key activation program correspondence table 64e, and the key item and the processing item extracted in step S495 are added. The corresponding data processing is executed (step S496).

Next, the CPU 61 determines in step S 496
It is determined whether or not the processing result of the processing executed in is obtained (step S497), and if not, the processing of step S497 is repeated until it is obtained,
If it is obtained, the processing result is stored and stored in the work memory 64g of the RAM 64 (step S498),
After the received mail analysis processing is completed, the process proceeds to the next processing (step S50) in the mail transmission / reception processing (FIG. 14).

Next, search processing as an example of processing executed in step S496 of the mail reception analysis processing (FIG. 15) will be described with reference to the flowchart shown in FIG.

According to the key item extracted from the text,
When the search processing program is started, the CPU 61 obtains search data such as a file to be searched, a key item, a search item, and the like from the processing object, the key item of the mail body, the processing item, and the like set in the extension header of the header portion. (Step S
61). For example, when an e-mail as shown in FIG. 7 is received, “customer MT” is obtained as a file, “customer code = 00001” is obtained as a key item, and “customer name” and “telephone number” are obtained as search items. I do.

Next, the CPU 61 generates an array for inputting search results (step S62). For example, when an e-mail as shown in FIG. 7 is received, a search result of a customer name and a telephone number must be obtained. Therefore, the array is represented by, for example, "customer name, telephone number". Generate.

Then, the CPU 61 accesses a search target file such as “customer MT” (step S63), and searches the search target file according to the key item (eg, “customer code = 00001”) read in step S61. (Step S64), and the data corresponding to the key item is stored in the RAM 64 (step S6).
5), end the processing.

Next, the mail shaping process (FIG. 14; step S38) executed by the CPU 61 of the terminal device 6 will be described with reference to the flowchart shown in FIG.

When the mail data created in the mail creation processing is determined (FIG. 14, step S37), the CPU 3
1 determines whether there is a key item for performing data processing in the created mail data (step S3).
81) If there is no key item, the process moves to step S385. If there is a key item, a normal header is added to the mail data (step S382), the key item for performing data processing is shaped according to a predetermined format (step S383), and a header for data processing is added. (Step S384), and it transfers to step S385.

In step S385, it is determined whether or not the mail data has a general body text. If there is no general body text, the processing is terminated, and the next processing (step S35) in the mail transmission / reception processing (FIG. 14) is performed. The process moves to step S39). If there is a general body text, a normal header has already been added, and it is determined whether or not there is (step S386). If there is a normal header, the process directly proceeds to step S388. If there is no normal header, a normal header is added (step S387), and the header and the body text are formatted according to a predetermined format (step S387). S388), the process ends, and the routine moves to the next process (step S39) in the mail transmission / reception process (FIG. 14).

Next, the processing result transmission processing (FIG. 14; step S50) executed by the CPU 61 of the terminal device 6 will be described with reference to the flowchart shown in FIG.

Received mail analysis processing (FIG. 14; step S)
49) is executed and the processing result is stored (FIG. 15;
In step S498, the CPU 61 converts the stored processing result data into a predetermined format (step S50).
1) A normal header is added to the processing result data converted into the predetermined format (step S502). Then, CP
U61 further adds a processing result header (step S5).
03), the data of the processing result is transmitted as mail data addressed to the portable terminal device 3 to the host device 4 via the server 5 by the transmission control unit 66 (step S504), and the processing result transmission processing is completed, and the mail transmission / reception is completed. The process moves to the next process (FIG. 14; step S51) in the process (FIG. 14).

In step S501, the predetermined format for converting the processing result data into a predetermined format may be, for example, a format specified in the mail data transmitted from the portable terminal device 3. . Further, for example, when the format of the processing result is specified in the data processing instruction of the mail data transmitted from the mobile terminal device 3, the processing result data is converted into a predetermined format, and You may make it convert into a format. For example, if the data processing instruction of the received mail data specifies that the processing result be in a file format and is returned as an email attachment, the processing result data is converted to the attached file format according to the specification. I do.

Next, mail reception / deletion selection processing (FIG. 14; step S) executed by the CPU 61 of the terminal device 6
45) will be described based on the flowchart shown in FIG.

When the server 5 has received a mail addressed to the terminal device 6 (FIG. 14; step S44), the CPU 61
Extracts the header information from the mail data (step S451), and refers to the extracted header information to determine whether the sender of the mail is a sender that satisfies the preset receiving conditions (step S451). S45
2). If the receiving condition is satisfied, step S45
Go to step 3 if not applicable, step S46
Move to 0.

In step S453, it is determined from the header information of the mail whether the mail has an attached file. If there is no attached file, the mail is received by the transmission control unit 66 (step S463), and the next processing (step S46) in the mail transmission / reception processing (FIG. 14).
When there is an attached file, it is determined whether or not the size of the attached file is equal to or larger than a preset size (step S454).

If it is determined in step S454 that the size of the attached file is equal to or larger than the set size,
The process moves to step S460. If it is determined that the size of the attached file is equal to or smaller than the set size, it is determined whether the attached file is a compressed file (step S455). If the file is a compressed file, the file is compounded in the receiving work directory (step S456), and the process proceeds to step S460. If it is not a compressed file, a character string that separates the attached file data from the body is detected (step S457). Since the data after the detected character string is data related to the attached file, the data related to the attached file is detected. The file name is extracted from the header information of the attached file data in (step S458).

Next, the CPU 61 determines in step S458
In step S459, it is determined whether the attribute of the attached file satisfies the preset receiving condition from the file name extracted in step S459. If so, the mail data is received (step S463). After the deletion selection processing is completed, the mail transmission / reception processing (FIG. 1)
The process moves to the next process (step S46) in 4). If the attribute of the attached file does not satisfy the preset reception condition, the process proceeds to step S460.

In step S460, the sender of the mail does not meet the receiving conditions, the size of the attached file is larger than the size set as the receiving condition, the attached file is a compressed file, It is determined whether to receive a mail whose attribute does not satisfy the reception condition, not to receive the mail, or to receive data other than the attached file. When it is determined that the mail is received, the mail data is received (step S46).
3), this mail reception / deletion selection processing is ended, and the next processing (step S4) in the mail transmission / reception processing (FIG. 14)
Go to 6).

If it is determined not to receive, the server 5
The mail data is deleted from (step S462)
The mail reception / deletion selection process is terminated, and the process proceeds to the next process (step S46) in the mail transmission / reception process (FIG. 14). If it is determined that data other than the attached file is to be received, only the text which is the data before the delimiter character string detected in step S457 is received (step S461), and this mail reception / deletion selection process is terminated. Then, the process proceeds to the next process (step S46) in the mail transmission / reception process (FIG. 14).
