FIG. 3 is a flowchart for explaining the transmission processing in the personal computer 2. First, the CPU 5 in the personal computer 2 reads out e-mail software from the hard disk memory 7 and creates a document to be transmitted by e-mail (step (hereinafter, referred to as ST)).
1). For example, if the document created at this time is the example shown in FIG. 4A, the characters “ABCDEF” surrounded by a frame, the number “123456” underlined, and the “Note ".

Next, the CPU 5 determines whether the text to be created has character modification (ST2). For example, this character modification means the above-mentioned frame, underline, emphasized character, and other halftone processing, color processing, etc. added to the text. In the case of the example of FIG. 4, the generated text includes the character modification. (ST2 is YES). If the created text does not include the character modification (NO in ST2), the CPU 5 immediately sends an e-mail (ST6).

On the other hand, if the created sentence includes a character modification, the CPU 5 extracts data other than the character (ST3).
Execute That is, in the example shown in FIG. 4B, a frame is extracted from the character “ABCDEF” surrounded by the frame as shown in FIG.
The underline is extracted from the numeral of "6", and the emphasized character area of "attention" is extracted as a normal character and the area of the emphasized character is extracted. Although not specifically shown in FIG. 4B, if there is an instruction for a character modification process such as a halftone process or a color process, the corresponding character modification process is extracted.

Next, the CPU 5 adds an identification header (ST4). This identification header is a header that informs that the above-mentioned character modification is present in the transmitted e-mail, and is added to identify the e-mail having no character modification. As this identification header, for example, “00”, “1”
Text data using an ASCII code such as "1" or "?" ! ! ? "And the like.

Next, the CPU 5 creates a file attached to the electronic mail (ST5). This attached file is composed of the above-mentioned header, data length (data length), and data part, and specifically has the configuration shown in FIG. That is,
As shown in FIG. 5A, for example, a header of “? !!?” And a data length (data length) indicated by “xxx”
,... Are composed of data portions.
In the data part, data indicating the address (position) of character modification to be added to the document and the type of character modification are described.
Specifically, as shown in FIG. 5B, an address (position) of character modification and data indicating the type of character modification are repeatedly described. For example, as shown in FIG. 3C, in the above example, a code indicating the address (position) to add a frame and the type of frame, an address (position) to add an underline and a code indicating an underline, emphasis, Each data of a character address (position) and a code indicating emphasis,... Is sequentially described. It should be noted that the above-described attachment file conversion process is also created by electronic mail software stored in the hard disk memory 7.

There are two types of attached files to be added on the sending side. Is sent as an attached file. In the above determination (W2), including both cases, it is determined whether any attached file is added.

If there is no attached file, display processing is immediately performed (W6). That is, if there is no attached file of the character modification and no attached file of the document created by the specific word processing software, only the text data (document data) is converted and displayed on the CRT display 15.

On the other hand, if there is an attached file, it is further determined whether or not the attached file is an attached file containing character modification information (W3). This determination is made based on the header added to the head of the attached file. That is,
As described above, if the code "? !!?" Is added to the header, it is determined that the file is an attached file including character modification information (YES in W3), and the attached file is decoded (W4). . If the file is not an attached file containing character modification information (NO in W3), display processing is immediately performed (W6). In this case, the attached file is an attached file of a document created by a specific word processing software, and the document is converted and displayed by the word processing software.

The attached file is decoded (W4).
The attached file having the configuration shown in FIG. 5 is analyzed and decompressed. In particular, the attached file is a process in which the electronic mail software stored in the hard disk memory 13 functions. For example, in the case of the attached file shown in FIG. 5, if the data part is analyzed, first, an address (position) to which the frame is added and a code indicating the type of the frame are read. Here, the address (position) of the frame is specified, for example, from the upper left coordinates and the lower right coordinates of the frame, and the type of character modification is analyzed as a frame from the code. Next, an address (position) to add an underline and a code indicating the underline are read,
The address (position) of the underline is specified, for example, from the coordinates of the left and right points of the underline, and the type of character modification is easily analyzed from the code as the underline.
Further, an address (position) to which emphasis (character) is added and a code indicating the emphasis are read out, and the address (position) of emphasis (character) and the type of character modification are analyzed in the same manner as described above.

Next, the CPU 11 performs a process of superimposing the above analysis result on the body of the electronic mail (W5). That is, as shown in FIG. 7, a frame is fitted to the character "ABCDEF" by this processing, an underline is added below the numeral "123456", and the character "caution" is a highlighted character. The data thus superimposed is C
It is displayed on the CRT display 15 under the control of the PU 11 (W6).

With the above processing, the character modification information in the attached file attached to the e-mail is superimposed on the e-mail document, and the CRT display 15
Will be displayed. Therefore, by performing the processing as described above, the character modification of the e-mail document can be easily performed without using word processing software.

Note that, as described above, the CRT display 15
The same data can be printed on a recording sheet by outputting the data displayed in the printer device 17 to the printer device 17. That is, from the personal computer 3 to the printer 1
7 to output the print data to the CRT display 1 described above.

The same data as the data displayed on the display 15 described above is developed as bitmap data in the image memory 20 by the analysis, execution, and drawing processing of 18, and the developed data is stored in the engine 28 under the control of the engine controller 27.
And print it on recording paper. <Second Embodiment> Next, a second embodiment of the present invention will be described.

The present embodiment is an invention in which an electronic mail transferred by the electronic mail system of the present embodiment is printed by form overlay. The system diagram of the above-described embodiment shown in FIG. 1 is also used in this embodiment.

That is, the e-mail system 1 is composed of a personal computer 2 on the transmitting side, a personal computer 3 on the receiving side, and a network 4 connecting the personal computers 2 and 3, and the personal computer 2 on the transmitting side has a CPU. A (processor) 5, a memory 6, and a hard disk memory 7 are provided. E-mail software is stored in the hard disk memory 7, and the CPU 5 performs an e-mail creation and transmission process based on the e-mail software. On the other hand, the receiving personal computer 3 is similarly provided with a CPU (processor) 11, a memory 12, and a hard disk memory 13, and the receiving personal computer 3 has a form registration memory 14
Is provided. In this example, the arrangement of the form registration memory 14 is particularly important.

The printer device 17 for performing form overlay printing according to this embodiment has the same configuration as that shown in FIG. 2, but the configuration of the storage unit 19 is particularly important. That is, the storage unit 19 stores form registration data described later. The other configurations of the printer device 17 are the same as those described above, and include the CPU 18, the image memory 20, the centro I / F
21, input / output control unit 22, panel I / F 23, panel control unit 24, operation panel 25, video I / F2
6, an engine controller 27 and an engine 28. The personal computer 3 and the printer device 17 are connected by a bidirectional centro interface, and print data output from the personal computer 3 is output to the centro I / F 21.

Hereinafter, the processing operation of this embodiment will be described. First, the personal computer 2 to the personal computer 3
Of the e-mail using the network 4 to the e-mail. This transmission process creates an e-mail according to the flowchart of FIG. 3 as described above. That is, the CPU 5 in the personal computer 2 reads out e-mail software from the hard disk memory 7 and creates a document to be transmitted by e-mail. For example, in the case of the example shown in FIG. 8A, an attached file is created by using a portion of a fixed format other than characters as a character modification portion.

That is, the CPU 5 determines whether or not the text to be created has character modification (ST2). In this example, the fixed format portion is used as a character modification portion (ST2 is YES), and portions other than characters are extracted (ST3). . For example, a ruled line pattern, a double-size area, a logo image, and the like are extracted. The part other than the fixed format is an ordinary e-mail document as form data. For example, in the example of FIG. 8, characters such as "contact document 001", "title", and "body" are transmitted as a text file.

Thereafter, the CPU 5 adds an identification header in the same manner as described above (ST4), and creates an attached file (ST4).
5). As described above, the attached file is created as an attached file including a header, a data length (data length), and a data portion.

The attached file created as described above is transmitted from the transmission / reception control unit 10 of the personal computer 2 to the personal computer 3 via the network 4 together with the electronic mail.

FIG. 9 is a flowchart for explaining the processing on the side of the personal computer 3 which has received the above-mentioned electronic mail. The CPU 11 in the personal computer 3
The e-mail input via the transmission / reception control unit 10 'is received by e-mail software stored in the hard disk memory 13.

First, when the CPU 11 receives an e-mail accompanied by an attached file (step (hereinafter referred to as S))
1) It is determined whether there is an attached file (S2). This determination is to determine whether an attached file is added to the e-mail. As in the above-described embodiment, there are two types of attached files to be added on the transmission side, and the character modification There is a case where the information is attached to a file, and a case where a document created by a specific word processing software is transmitted as an attached file. In the above determination (S2),
It is determined whether any attached file is added, including both cases.

If there is no attached file, the process is immediately terminated. In other words, if there is no attached file of the character modification and no attached file of the document created by the specific word processing software, only the text data (document data) is converted and the process is terminated.

On the other hand, if there is an attached file, it is further determined whether or not the attached file is an attached file containing character modification information (S3). This determination is made based on the header added to the head of the attached file. That is,
As described above, if the code "? !!?" Is added to the header, it is determined that the file is an attached file including character modification information (YES in S3), and the attached file is decoded (S4). . If the file is not an attached file containing character modification information (S3: NO), the process is immediately terminated.

The attached file is decoded (S4).
The attached file having the configuration shown in FIG. 5 is analyzed and decompressed. In particular, the attached file is a process in which the electronic mail software stored in the hard disk memory 13 functions. For example, in the case of the attached file shown in FIG. 8, if the data part is analyzed, a ruled line pattern in a fixed format, a double-size area, a logo image, and the like are decompressed.

Next, the CPU 11 stores the decoded data of the attached file in the storage medium (S5). That is, the form registration memory 1 of the personal computer 3
4, that is, in the case of the above example, the ruled line pattern in the fixed format, the double-size area, the address (position) of the logo image, and the character modification data are registered in the form registration memory 14 as form registration data.

After the e-mail receiving process is completed as described above, the printer 17 performs form overlay printing. FIG. 10 is a flowchart illustrating this printing process.

First, when performing printing processing by the printer 17, the CPU 18 determines whether or not there is an overlapping form (step (hereinafter, referred to as STP) 1). Here, when there is an overlapping form, the instruction is for form overlay printing, and when there is no overlapping form, the instruction is for normal printing. This determination is made by the CPU of the personal computer 3.
11 judges by checking the form registration memory 14.

In the case of this example, as described above, the above-described form registration data is stored at this time, and it is determined that there is an overlapped form (STP1 is YES). Therefore, in this case, the form data of the fixed format shown in FIG. 8 stored in the form registration memory 14 is transmitted to the printer device 17 (STP2). Then, a form generation instruction is given (STP3). On the other hand, the printer 17 stores the fixed format supplied from the personal computer 3 in the storage unit 19. Then, in accordance with the above-described form generation instruction, the CPU 18 draws form data in a fixed format.

Next, the body of the electronic mail from the personal computer 3, that is, the above-mentioned “contact document 001”,
The document data such as “title” and “body” is transmitted to the printer 17 (STP4). When the above-described document data is input to the printer 17, the data is superimposed on the above-described fixed form as the data to be formed, and is drawn in the image memory 20. FIG. 8 shows the image data in a superimposed state.

The superimposed image developed in the image memory 20 in this manner is output to the engine 28 under the control of the engine controller 27, and is printed on a recording sheet by form overlay printing. When the form overlay printing is completed, the CPU 18 determines that there is an overlapping form (ST18).
P5 is YES), an instruction to end the form generation is issued (ST)
P6), the recording paper is discharged, and the processing is terminated (STP
7).

By performing the above processing, the fixed format in the attached file attached to the e-mail is superimposed on the document of the e-mail, and printed on the recording paper by the printer 17.

Note that by performing form overlay printing as described above, it is possible to easily print a large number of document data sent by e-mail in the same fixed format.

[0065]

According to the present invention as described above, the following effects can be obtained. According to the present invention, an electronic mail document with character modification can be transmitted and received without using word processing software.

Form overlay printing can be performed using a fixed format in an attached file attached to an electronic mail.
