Further, the CPU 2 can also sequentially execute the operation according to the program code transmitted via the transmission medium. That is, in addition to the storage medium, the program /
An operation unique to the present embodiment can be executed using data.

FIG. 5 is a flowchart showing the flow of the mail sending / receiving process. In FIG. 5, first, the CPU 2 causes the display device 4 to display an operation screen for mail transmission / reception in accordance with the application program (step S1), determines whether or not there is a key input on the input device 3 (step S2). If not (step S2; N
O), the standby state for the key input is continued. If there is a key input (step S2; YES), the CPU 2
The processing mode selected by key input from among the “mail creation”, “mail reception”, and “other” processing is determined (step S3).

In step S3, when the user selects the "create mail" process by the input operation using the input device 3,
Each processing of steps S4 to S9 is executed. When the “other” process is selected in step S3, the process shown in step S10 is executed, and in step S3,
When the "reception" process is selected, the processes in steps S11 to S17 are executed.

First, steps S4 to S9 executed when the "mail creation" process is selected will be described.

The CPU 2 displays a screen for inputting the contents of the outgoing mail on the display device 4 and prompts the user to input the contents of the mail (step S4). Next, when the destination of the mail is input (step S5), the CPU 2 sets the “transmission key”
Alternatively, it is determined whether or not there is a pressing operation of the "release key" (step S6).

When the "send key" is depressed (step S6; send key), the CPU 2 reads out a preset own mail address and sets the mail address as a sender in a predetermined area in the work memory 6h. Store temporarily. Then, the CPU 2 connects the personal computer 1 to the network via the transmission control unit 7 (step S7), and transmits the mail of the text content input in step S4 to the mail address set as the transmission destination in step S5 (step S5). S8). And CPU2
Disconnects the connection with the network upon completion of the mail transmission (step S9), returns to step S1, displays the operation screen for transmitting and receiving the mail on the display device 4, and performs the key input on the input device 3. And the subsequent processes are repeatedly executed.

When it is determined in step S6 that the "release key" has been pressed (step S6; release key),
The CPU 2 initializes the contents stored in the work memory 6h and the mode contents selected in step S3, returns to step S1, and repeats the subsequent processing.

Next, step S10 executed when "other" processing is selected in the mode selection of step S3 will be described. In step S10,
The CPU 2 sets the automatic change flag 6d according to an input instruction from the input device 3. When the setting is completed, the process returns to step S1 again, and the subsequent processes are repeatedly executed.

Next, steps S11 to S17 executed when the "mail reception" process is selected in the mode selection of step S3 will be described. In step S3, when the “mail reception” process is selected by an input operation from the input device 3, the CPU 2 connects the personal computer 1 to the network via the transmission control unit 7 (step S11).

Next, the CPU 2 reads out a preset own mail address and determines whether or not there is a received mail addressed to the mail address (step S12). If there is no received mail (step S12; NO), step S
Move to 17. If there is a received mail (step S12; YES), the CPU 2 receives the mail via the transmission control unit 7 and temporarily stores it in the RAM 6 (step S13). Then, the CPU 2 causes the display device 6 to display the received mail content together with additional information such as the sender (source mail address) and the date and time of reception (step S1).
4), execute the attached file storage process shown in FIG. 6 (step S15).

FIG. 6 is a flowchart showing the flow of the attached file storage process. Details will be described with reference to FIG.

First, the CPU 2 determines whether or not an attached file is added to the received mail displayed on the display device 4 (step S21). If the attached file is not added (step S21; NO), step S3
Move to 4. If the attached file has been added (step S21; YES), the CPU 2 obtains a source mail address, which is additional information of the received mail (step S22).

Next, the CPU 2 determines whether the address recognition flag 64a set in the mail address memory 6a is set to "1" or "0" (step S23). If the address recognition flag 64a is set to "1" (step S23;
On (“1”), the CPU 2 recognizes that the attached file has been transmitted from the person to be deleted, and displays a deletion confirmation display for the person to be deleted (see FIG. 4E) on the display device 4 (step S).
24), and proceed to step S36.

If the address recognition flag 64a is set to "0" (step S23; OFF "0"), the CPU 2 determines whether a file having the same name as the attached file name exists in the attached file folder 6b. It is determined whether or not it is (step S25).

If a file having the same name as the attached file name exists in the attached file folder 6b (step S2)
5; YES), proceeding to step S26, and step S2
6 to S32 and steps S35 to S40 are executed. If there is no file having the same name as the attached file name (step S25; NO), the process shifts to step S41 and executes the processes of steps S41 to S45.

First, steps S26 to S32 and step S3 executed when a file having the same name as the attached file name exists in the attached file folder 6b.
Steps 5 to S40 will be described.

In step S26, the content comparison processing between the current file and the previous file shown in FIG. 7 is executed.

FIG. 7 is a flowchart showing the flow of the content comparison processing between the current file and the previous file.
In FIG. 7, first, the CPU 2 extracts a file (previous file) having the same name as the current file (the file attached to the received mail) from the attached file folder 6b and determines whether or not the storage capacities are the same. (Step S51). If the storage capacities are not the same (step S5
1; NO), the process proceeds to step S58, and the CPU 2 recognizes the mismatch, and proceeds to the next process (step S27 in FIG. 6 or step S74 in FIG. 9).

If the storage capacities are the same (step S51; YES), the CPU 2 sets the count value n of the mail text line number counter 6f to 1 (step S5).
2). Next, the CPU 2 determines n corresponding to the count value n.
It is compared whether the characters and symbols on the line are the same between the current file and the previous file (step S53). Then, the CPU 2 determines whether or not the contents of the compared n-th row match (step S54). If the contents do not match (step S54; NO), the process proceeds to step S58. If the contents match (step S54; YE
S), the CPU 2 determines whether or not the mail text ends at the n-th line (step S55).

If the mail text does not end on the n-th line (step S55; NO), the CPU 2 increments the count value n (step S56), returns to step S53, and repeats the processing of steps S53 to S55.

If the mail message ends at the n-th line (step S55; YES), the CPU 2 recognizes that the current file and the previous file are the same (step S57), and executes the next processing (FIG. Step S27 of 6, or
The process moves to step S74) shown in FIG.

Then, in step S27 of FIG.
The CPU 2 determines whether or not the file contents compared by the contents comparison processing are the same. If the file contents are the same (step S27; YES), the process proceeds to step S35, and the CPU 2 displays a deletion confirmation on the display device 4 (FIG. 4).
(See (a)). And yeso from user
In response to an instruction to input r No (step S36), the CPU 2
Determines whether to delete the attached file (step S37).

If there is an instruction to delete the attached file according to the input instruction of Yes (step S37; YES), the CPU 2
Stores the attached file name in 6c in the deleted attached file history (step S38), and deletes the attached file (step S39). Then, the CPU 2 adds a message “the attached file has been deleted” to the body of the received mail together with the attached file name (step S40),
Move to step S34.

If there is no instruction to delete the attached file according to the input instruction of No (step S37; NO), the process proceeds to step S28.

In step S28, the CPU 2 sets the automatic change flag 6d to "1" (ie, auto).
Or "0" (that is, manual) (step S28).

If the automatic change flag 6d is set to "0" (step S28; NO), the CPU 2 displays a file name change confirmation display (see FIG. 4C) on the display device 4, and Input device 3 with changed file name
(Step S31), and it is determined whether or not a confirmation signal has been input from the input device 3 (step S31).
32). Then, when the determination signal is input from the input device 3 (Step S32; YES), the process proceeds to Step S33, and when the determination signal is not input from the input device 3 (Step S32; NO), the process returns to Step S31. .

If the automatic change flag 6d is set to "1" (step S28; YES), the automatic file name creation processing shown in FIG. 8 is executed (step S2).
9).

FIG. 8 is a flowchart showing the flow of the automatic file name creation processing. In FIG. 8, first, the CPU 2 converts the extension (txt) of the attached file name (for example, ABC.txt) of the attached file folder 6b.
Then, a file name portion (for example, ABC) excluding is extracted (step S61). Next, the CPU 2 obtains the current date (for example, May 17, 2000) from the clock unit 8 (step S62), and obtains the last two digits of the current date obtained after the extracted file name (for example, , 00), month (for example, 0
5) Add a date (for example, 17) and create a new file name (ABC000517) of the attached file (step S6).
3).

Then, the CPU 2 determines whether or not the created new file name is the same as another file name stored in the attached file folder 6b (step S64). If the created new file name is the same as another file name (step S64; YES),
The CPU 2 adds a serial number after the file name, for example, in the order of the file existing in the attached file folder 6b and the file with the new file name (for example, ABC000517).
(1) and ABC000517 (2). ) (Step S6)
5). If the created new file name does not overlap with another file name (step S64; NO), the process moves to the next process (step S33 or step S45 in FIG. 6).

Next, steps S41 to S45 executed when a file having the same name as the attached file name does not exist in the attached file folder 6b will be described.

First, in step S41, the same content file discrimination processing shown in FIG. 9 is executed.

FIG. 9 is a flowchart showing the flow of the same content file determination process. In FIG. 9, first, C
PU2 sets the count value x of the attached file NO counter 6g to 1 (step S71). Then, CPU
2 is the count value x from the attached file folder 6b.
The file contents of the attached file NO'x 'corresponding to the file No. are read out and set as the previous file (step S7).
2). Then, the CPU 2 executes the above-described content comparison processing (FIG. 7).
(See step S73), and in the content comparison process, the recognized attached file name (for example, DEF.txt) having the same content is temporarily stored in the work memory 6h (step S74).

Then, the CPU 2 sets the attached file number
The 'x'th attachment is the attachment folder 6b
It is determined whether the file is the newest file stored in (step S75). If the attached file NO'x 'is not the newest file (step S75; NO), the count value x is incremented (step S76), and the process returns to step S72 to step S7.
2 to S75 are repeated. In addition, attached file N
If the O'x'th attached file is the newest file (step S75; YES), the process moves to the next process (step S42 shown in FIG. 6).

Then, in step S42 of FIG.
It is determined whether or not there is an attached file name of the same content temporarily stored in the work memory 6h. If there is no attached file name of the same content (step S42; NO), step S42 is performed.
Move to 33. If there is an attached file name having the same content (step S42; YES), the file name having the same content is read (step S43), and the above-described automatic file name creation processing (see FIG. 8) is executed (step S44).
The attached file name before the change is added to the mail text (step S45), and the process proceeds to step S33.

Steps S26 to S32 or step S4
After executing each of the processes 1 to S45 and proceeding to step S33, in this step S33, the CPU 2 stores the file name and the contents in the attached file folder 6b.

Then, the CPU 2 stores the mail document in the received mail folder 6e (step S34), and shifts to the next processing (step S16 in FIG. 5).

Then, in step S16 of FIG.
The CPU 2 determines whether or not the mail receiving process is completed,
If the mail receiving process is completed (step S16; N
O), and return to step S12.

If the mail receiving process is not completed (step S16; YES), CPU 2 disconnects from the network upon completion of mail transmission (step S9), and returns to step S1 again. , An operation screen for sending and receiving mail is displayed on the display device 4, and the input device 3 is displayed.
And enters the standby state for the key input at the same time, and the subsequent processing is repeatedly executed.

As described above, in the reception mode of the mail transmission / reception processing, when a file is attached to the received e-mail, the CPU 2 determines the attached file and the file already stored in the attached file folder 6b. The file name and the contents of the file are compared, and if it is recognized that the file name or the file contents are the same, the attached file is deleted while the history of the file name is left in the deleted attached file history 6c.

Further, when an attached file from a specific sender set as a person to be deleted is received by the address recognition flag 64a of the mail address memory 6a, the CPU 2 displays the mail address and the sender name as confirmation display. The attached file history 6 is displayed on the display device 4 according to an input instruction from the input device 3 by the user.
c, leaving the history of the file name and deleting the attached file.

Further, the CPU 2 compares the file name and the contents of the attached file of the received e-mail with the file already stored in the attached file folder 6b.
Even when it is recognized that a file having the same file name does not exist, the contents of the attached file and the file already stored in the attached file folder 6b are compared. Change your name.

Therefore, if a received mail has an attached file, if there is already a file with the same file name and the same file content, the attached file can be prevented from being saved (that is, deleted). 9 can be saved, and the subsequent editing and search processing can be improved. Also, when an attached file is deleted, an attached history of the deleted file can be left, so that it is possible to check the attached history.

When a received mail has an attached file, if the file with the same file name already exists, the attached file name can be changed automatically or manually, so that the user can input the file name automatically. You can also change the file name, which makes it easy to distinguish between files.

Also, if a received mail has an attached file and a file with the same file content already exists,
Since the file name of the attached file can be changed and stored, waste of the storage capacity of the storage device 9 can be eliminated.

In the above embodiment, the history is left in the deleted / attached file folder history 6b, and the attached file is deleted. However, the present invention is not limited to this. The attached file may be opened by holding it.

[0090]

According to the first and seventh aspects of the present invention, an attachment file received in the past is stored, and the names and contents of the stored attachment file and the file attached to the received mail are compared. When the content of each attached file having the same name is the same, by deleting the attached file, a file having the same name and the same content can be easily deleted.

According to the second aspect of the present invention, when the content of each attached file having the same name is different, the file name is automatically changed by adding date and time information to one of the file names, so that the attached file is automatically changed. Files can be easily identified.

According to the third and eighth aspects of the present invention, a specific sender is stored, it is determined whether or not the sender of the received mail is the specific sender. Since the file attached to the e-mail is deleted, the attached file unnecessary for the user can be easily deleted.

According to the fourth aspect of the invention, when deleting a file attached to a received mail, the deletion information of the attached file is stored, so that the deletion history of the attached file can be easily confirmed.

According to the fifth and ninth aspects of the present invention, the attached file received in the past is stored, and the names and contents of the stored attached file and the file attached to the received mail are compared. When the contents of each attached file are the same, by changing the file name attached to the received mail, it is possible to make the attached files having duplicate contents have relevance to facilitate identification.

According to the sixth aspect of the present invention, the attached file name of the received mail and the stored attached file name are changed to a related name, so that the attached files having the same contents can be easily identified. it can.
