DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS One embodiment of the present invention will be described below with reference to the drawings. In this embodiment, it is assumed that the image data is transmitted as e-mail, the received e-mail is printed as image data, and the Internet is used as a computer communication network.

As shown in FIG. 1, the communication terminal device T is G3
And a function for communicating with the Internet in addition to the G4 facsimile communication function. The CPU 1 controls each unit of the communication terminal device T via the bus 12, and performs an encoding process, a decoding process, an image conversion process, which will be described later.
Executes software for binary / text conversion processing, mail editing processing, communication procedure processing, etc.

The reading section 2 includes a charge coupled device (CCD).
The image on the document is read by ice) or the like, and binary black and white image data is output. The recording unit 3 includes a paper cassette (not shown) containing recording paper. The sheet size in the sheet cassette is detected by a sensor (not shown), and the detection result is notified to the CPU 1. The recording unit 3 includes an electrophotographic printer or the like, and prints image data received from another G3 or G4 facsimile apparatus or e-mail received from the Internet as image data on recording paper.

A display unit 4 such as an LCD (Liquid Crystal Display) displays the operating state of the communication terminal device T and image data. The operation unit 5 includes a numeric keypad, speed dial keys, one-touch dial keys, various function keys, and the like necessary for operating the communication terminal device T, and a setting list key 5a for printing out various setting lists. Have. The setting list is a list of various setting information registered in the communication terminal device T, for example, a setting list indicating registered contents of speed dial keys and one-touch dial keys, a setting list of a font (font) type described later, and the like. There is. Further, communication management information may be included as a setting list.

A ROM (Read Only Memory) 6 stores software necessary for the operation of the communication terminal device T and also stores data of various fonts (for example, Gothic, Mincho, Italic, etc.). I have. RAM (Rand
om Access Memory (SRAM) 7 is an SRAM (Static Random Ac).
cess Memory) or flash memory (flash E)
EPROM; Flash Electrically Erasable Programmab
le Read Only Memory) and stores temporary data generated during software execution.
The setting list data is stored. Furthermore, RAM
Reference numeral 7 stores the relationship between the type of information in the e-mail and the font type to be used for printing each information in a font table T1 as shown in FIG. The types of information in an electronic mail are roughly classified into a header and a text. Further, the header is divided into "from:" (sender) and other information. The text is divided into quotes and other information. In the font table T1 shown in FIG. 5, a setting list, which is information other than electronic mail, is also registered as a type of information, and a font type to be used for printing the setting list is also set. The setting contents of the font table T1, that is, the setting of which information is to be printed in which font type, may be registered in advance, or may be arbitrarily changed by a setting key (not shown) of the operation unit 5. You may.

In this embodiment, the detection means, the control means, and the discrimination means are constituted by the CPU 1, the ROM 6, and the RAM 7. The image memory 8 is a DRAM (Dynamic Ra
mdom Access Memory) and temporarily stores image data to be transmitted and received image data.

DSU (Data Line Terminator; Digital Se
rvice Unit) 9 is connected to the digital line L1. Data transmitted on the digital line L1 is transmitted according to a baseband transmission method. For this reason, DSU
Numeral 9 converts the transmission data as a digital signal into a change in voltage and sends it to the digital line L1, and converts the voltage change on the digital line L1 into a digital signal as reception data.

The modem 10 modulates and demodulates transmission / reception data, and has a data modem function in addition to a conventional FAX modem function. NCU (Network Control
l Unit) 11 has a function of closing and opening the analog line L2 and detecting the transmission and reception of dial pulses corresponding to the fax number of the other party.

FIG. 2 schematically shows a data flow in the communication terminal device T according to the present embodiment. Note that, in the figure, the encoding / decoding unit 21, the image conversion unit 2
2. Binary text converter 23, mail editor 2
4. The auto dialer 25 indicates a function executed by the CPU 1 based on software stored in the ROM 6.

The encoding / decoding unit 21 converts the image data into an MH (Modified Huffman) system and an MR (Modified REA).
D) Encoding or decoding is performed by an encoding method such as a method or an MMR (Modified MR) method. Hereinafter, the image data encoded by these encoding methods is referred to as “G3 format image data”. The image memory 8 stores the G3 format image data.

At the time of transmission, the image conversion unit 22 converts G3 format image data into TIFF (Tag Image File For) which is a general image format used by a computer.
mat), and from TIFF to G3 format image data upon reception. Here, TIFF is the United States
This is a standard format for image files proposed by Aldus (currently merged with Adobe Systems). Instead of specifying a standard data format, TAG is used for image data attributes.
The feature is that it is defined as (tag) information. For this reason, in the case of the TIFF format, the data format can be recognized by reading the standardized tag information described in the first several hundred bytes of the image file.

Also, TIFF is not limited to black and white binary,
Various Classes that handle monochrome multi-valued, full color, etc. are defined. One of them, Class F, defines G3 format image data. Therefore, the image data can be converted to TIFF by adding TIFF header information of Class F to the head of the G3 format image data. Hereinafter, the G3 format image data to which the Class F TIFF header information is added is referred to as “TIFF image data”.

The binary / text converter 23 converts binary data to text data at the time of transmission, and converts text data to binary data at the time of reception. Since there are computers on the Internet that cannot handle binary data e-mails, when sending binary data such as TIFF image data, text data must be sent once to ensure that the e-mail reaches the destination. Need to be converted to Text data handled on the Internet is IETF (Internet Engineering T
RFC (Req), a document issued by ask Force)
uest For Comments) 822, as a 7-bit code.

Therefore, the binary / text converter 23
Is MIME (Multipurpose Internet Mail Extension)
Data conversion is performed using base64 or the like in s).
According to this base64, 6-bit binary data is composed of 64 characters (uppercase, lowercase alphabet,
It can be replaced with one of numbers, +, /) and padding (=), and can be converted to text data. MIME is defined by RFC1521 (definition of MIME header), RFC1522, and RFC1590.

The mail editing section 24 adds mail header information to the TIFF image data converted to text data at the time of transmission to edit the data into an electronic mail format, removes the mail header information from the data of the electronic mail format at the time of reception, Only the TIFF image data converted into data is extracted. Since it is specified that predetermined header information is added to Internet e-mails, "From:" is added to the head of TIFF image data at the time of transmission based on data or the like registered in the RAM 7.
Items such as (sender), “To:” (destination), “Subject:” (title), “Cc:” (copy and distribution), and “Date:” (date) are added.

The auto dialer 25 uses the numeric keypad, speed dial key or one-touch dial key of the operation unit 5 to make a call to the telephone number entered by the DSU 9,
The other party's telephone number data is sent to the modem 10 or the NCU 11.

Next, the operation of the communication terminal device T of the present embodiment will be described with reference to the flowcharts shown in FIGS. This operation is executed by the CPU 1 based on a program stored in the ROM 6.

As shown in FIG. 3, it is determined whether the reception of the electronic mail from the computer communication network has started (S1). If no e-mail has been received (in other words, in a communication standby state), it is determined whether or not the setting list key 5a has been turned on (S2). Setting list key 5a
If is not ON, the process returns to S1. Setting list key 5a
Is ON, it is determined that the printing of the setting list has been instructed, and the font No. as the font type to be used for printing is determined based on the font table T1 of FIG. 1 (for example, Gothic) is set (S3). And R
The setting list data in AM7 is read out,
The list data corresponds to the set font No. 1
Printing is performed in (gothic) (S4), and the process ends.

In step S1, when the reception of the electronic mail is started, the electronic mail is received one line from the beginning (S5). Next, the content of the received e-mail for one line is analyzed, and it is determined whether or not it is a specific character code (S6). The specific character code is "Bounda
ry (boundary) ”or“. (period) ”to indicate the end of the email. A Boundary usually exists between the header and the body of an email.

If the e-mail for one line has a specific character code in S6, it is determined whether the character code is ". (Period)" indicating the end of the e-mail (S7). ). If the specific character code is not a period indicating the end of the electronic mail, that is, if it is a Boundary, “1” is counted to count the Boundary, and the Boundary is converted into a character code string delimited (S8). ), And proceeds to S9. As the character code string of the delimiter, for example, a character code of "-" is continuous for one line, and this is a broken line between the header and the body of the e-mail. On the other hand, S6
If the received one-line e-mail is not a specific character code string, the process directly proceeds to S9.

Next, in S9, it is determined whether or not the count value of Boundary is "0 (zero)". When the count value is “0” (that is, when Boundary has not been received yet), it is determined that the received e-mail for one line is the header information. Then, the flow shifts to S10, where it is determined whether the e-mail for one line is "From:" which is one of the items of the header information. If it is not “From:”, “Font No. 1” (for example, Gothic type) is set as the font type to be used for printing based on the font table T1 in FIG. 5 (S11), and the process proceeds to S16. In the case of “From:”, “Font No. 2” (for example, underlined Gothic font) is set as the font type to be used for printing based on the font table T1 of FIG. 5 (S12), and the process proceeds to S16. On the other hand, the S
9, when the count value is not "0" (that is,
If the Boundary has already been received),
It is determined that the electronic mail for the line is not the header information but the body, and the process proceeds to S13.

In S13, it is determined whether the e-mail for one line is a quote. Here, the determination as to whether or not it is a quote is made based on whether or not the character code at the beginning of the e-mail for one line is “>”. If the text is not a quote, the font type to be used for printing based on the font table T1 in FIG.
(For example, Mincho) is set (S14), and the process proceeds to S16. This “font No. 3” is also set for the delimited character code string converted in S8. In the case of a quote, "Font No. 4" (for example, italic) is set as the font type to be used for printing based on the font table T1 of FIG.
15) The process proceeds to S16.

In S16, one line of e-mail and data relating to font type setting are stored in the RAM 7. In S17, the number of rows is counted, and thereafter, the process returns to S5.

In S7, if the specific character code is ". (Period)" indicating the end of the e-mail, 1
It is determined that the reception of the e-mails for the case has been completed, and the period is stored in the RAM 7 (S18), and then the number of lines is counted (S19). The count value of the number of lines is stored in the RAM 7 as the total number of lines of one electronic mail. Then, after the Boundary and the count value of the number of lines are cleared, it is determined whether there is an e-mail to be received next (S20). If there is an e-mail to be received next, the process returns to S5. If there is no e-mail to be received next, the process proceeds to S21 in FIG.

In S21 of FIG. 4, the maximum number of lines that can be printed at a standard font size (for example, "12" points) set in advance on the recording paper according to the size of the recording paper in the paper cassette Is set. For example,
If the recording paper is “A4” size, the maximum number of lines is “28”.
Line ". Next, it is determined whether the number of lines of one received mail is equal to or less than the maximum number of lines (S22). Note that the division of each received mail can be determined by a period.
1 if the number of lines in one received mail is less than the maximum number of lines
It is determined that the number of e-mails can be printed on one sheet of recording paper in the standard font size, and the font size FS1
(Standard points, for example, "12" points) are set (S23). Then, one e-mail is printed on one sheet of recording paper in the font type and font size set previously (S27), and the process proceeds to S28.

If the number of lines of one e-mail exceeds the maximum number of lines in S22, the process proceeds to S24, where 1
It is determined whether the number of lines of the e-mail for the case exceeds the maximum number of lines and is equal to or less than a threshold. Here, the threshold value is, for example, the maximum number of lines that can be printed on one sheet of recording paper with a font size smaller by 2 points than the standard font size (12 points).

If the number of lines of one electronic mail exceeds the maximum number of lines and is equal to or smaller than the threshold, the font size FS2 (10 points smaller than 12 standard points by 10 points) is set (S25). Then, one e-mail is printed on one sheet of recording paper in the font type and font size set previously (S27), and the process proceeds to S28. In this printing, the font size is reduced by two points from the standard font size set in S23, so that the line spacing is reduced by that amount.
As a result, one email can be printed on one recording sheet.

If the judgment result in S24 is NO, that is, 1
If the number of lines of the e-mail for the case exceeds the threshold, the font size FS1 is set so that the e-mail is printed on a plurality of pages (S26). Then, one e-mail is printed on a plurality of recording papers with the font type and font size set earlier (S2).
5), proceed to S28.

In S28, it is determined whether there is an e-mail to be printed next. If there is an e-mail to be printed next, the process returns to S21. If there is no e-mail to be printed next, all the processes are terminated.

FIG. 6 exemplifies a print result of the received mail. As shown in the figure, the first broken line 31 indicates the boundary between the header and the text. Header is font N
o. 1 (Gothic), and the text is font No. 3 (Mincho style) is printed. In particular, “form:” in the header is the font No. 2 (underlined gothic type), the text quoted in the text is font No. 4 (Italic)

As described above, according to the present embodiment, the following effects can be obtained. (1) If the specific character code in the e-mail is Boundary, it is printed as a broken line. For this reason, as shown in FIG. 6, the distinction between the header part and the text in the printed and output e-mail can be clearly recognized by the dividing line. Also, since the fonts are different between the header and the body, the distinction is further facilitated, and the mail is easy to read.

(2) Since the header “from:” in the printed e-mail has a different font from those other than “from:”,
The sender of the mail can be easily determined. On the other hand, in the text, the quote is different from other parts in the font, so that the quote can be easily identified only by glance at the e-mail.

(3) If one mail cannot be printed on one sheet of recording paper in the standard font size, the mail is printed in a font size smaller than the standard font size so that the mail fits on one sheet of recording paper. . For this reason, one mail can be easily confirmed on one sheet of recording paper,
Waste of recording paper can be suppressed.

(4) When the number of lines of one received mail exceeds the threshold, the electronic mail is printed in a standard font size on a plurality of recording papers. For this reason, it is possible to prevent the printed characters from becoming too small and difficult to see.

(5) If the font type corresponding to the type of information in the received mail is changed by key operation of the operation unit 5, the font type according to the user's preference can be set freely.

The above embodiment may be modified as follows. Even in such a case, at least the same effects as those of the above embodiment can be obtained. (A) Since the header information is received until the first Boundary is received, a change is made so that a page break is performed at the first Boundary when printing a mail. By doing so, the header and the body are printed on separate recording papers.

(B) In S24, when the number of lines of one electronic mail exceeds the maximum number of lines and is equal to or smaller than the threshold,
By changing the font size to the standard 12 points and reducing the line spacing, one mail is printed on one sheet of recording paper.

(C) In S24, when the number of lines of one e-mail exceeds the maximum number of lines and is equal to or smaller than the threshold,
Instead of setting the font size FS2 (the size of a character two points smaller than the standard point), after converting the received mail into image data, the entire image data is reduced and printed. thing.

(D) In S24, when the number of lines of one e-mail exceeds the maximum number of lines and is equal to or smaller than the threshold,
Set the font size to a font size that is at least three points smaller than the standard font size.

(E) Information in the received mail,
For example, the characters in the header may be made larger than the characters in the body. When the recording unit 3 is a color printer, the color of the characters to be printed is changed according to the type of information in the received mail. For example, print the header red and the body blue.

(F) The processing in the case where the judgment result in S10 is YES is changed as shown in the flowchart of FIG. That is, if the determination result in S10 is YES, it is determined whether or not the sender indicated by "from:" is a partner registered in the speed dial key or the one-touch dial key (S31). If the registered partner is the font No. 5 is set (S32),
If the other party is not registered, the font No. 2 is set (S33), and then the flow shifts to S16. In addition, font No. 5 is a font No. 1 to No. 4
And different.

In this way, whether the sender of the mail is the party registered in the speed dial key or the one-touch dial key (that is, the party who frequently communicates)
It is easy to determine whether the user is an unregistered one (an infrequently communicating party).

(G) The processing when the result of the determination in S10 is NO is changed as shown in the flowchart of FIG. That is, if the determination in S10 is NO, one line of the received mail is one of the items of the header information "T
o: ”is determined (S41). If it is not “To:”, “Font No. 1” is set (S44) and S
Move to 16. In the case of "To:", it is determined whether or not the destination name indicated in "To:" is a destination name registered in the RAM 7 in advance (S42). In the case of a registered destination name, “Font No. 6” is set (S43),
Move to S16. If the destination name is not registered,
“Font No. 1” is set (S44), and the flow shifts to S16. Note that this “font N0.6” is a font type different from at least “font N0.1” and “font N0.2”.

In this way, if the receiving user registers his / her name and the like in the RAM 7 in advance, it is possible to easily determine whether or not the electronic mail is addressed to the user. (H) As shown in FIG. 9, a table in which the maximum number of lines that can be printed on recording paper of each size is set for each font size is stored in the RAM 7. Then, according to the size of the recording paper in the paper cassette and the number of lines of one received mail, a font size that can print the mail on one recording paper is set. For example, the received e-mail has 31 lines and the size of the recording paper in the paper cassette is “A”.
In the case of "4", the font size of the character is set to "10" points from the table. When the number of lines of the received mail exceeds the maximum number of lines set in the table, the received mail is, for example, 12 points of the standard point.
Printed over multiple pages at points.

(I) In the above embodiment, the cut paper is used as the recording paper, but it may be embodied by an apparatus provided with roll paper. In this case, when one received mail is printed over a plurality of pages, a separator line indicating the break of one page is printed with a length corresponding to the length of a standard size cut sheet, or one page is printed. You may make it cut each time. Further, a configuration may be adopted in which a separator line is printed or cut for each electronic mail of one case.

(J) Changing the font according to the size of the character to be printed. In other words, some fonts are easy to see even with small characters, so if the characters to be printed are small, if the fonts are small and easy to see, the mail will not be difficult to read.

Further, technical ideas other than the claims grasped from the embodiment will be described below together with their effects. (1) The communication terminal device according to claim 2, wherein the recording unit is a color printer, and the control unit changes a color used for printing in the recording unit according to a type of information determined by the determination unit.
