Various programs and data in the external storage device 1f and ROM 1e can be expanded.
[0019]
The display unit 1d is configured by a CRT (Cathode Ray Tube), an LCD (Liquid Crystal Display), or the like, and performs screen display of various display data according to a display instruction input from the CPU 1a.
[0020]
The ROM 1e is a read-only memory, and stores application programs such as a system program and an e-mail display program, predetermined data, and the like. The ROM 1e may be a data rewritable flash ROM.
[0021]
The external storage device 1f has a recording medium 1g in which programs and data are stored or writable in advance, and the recording medium 1g can be read by the CPU 1a such as a magnetic or optical recording medium or a nonvolatile memory such as a semiconductor. It is composed of a simple recording medium. The recording medium 1g includes a fixed medium provided on an external storage device 1f such as a hard disk or a portable medium such as a CD-ROM or a memory card that is detachably mounted. The recording medium 1g stores various processing programs and various data such as data processed or processed by these programs. The RAM 1c and the external storage device 1f are configured to be able to rewrite internal data under the control of the CPU 1a.
[0022]
In addition, a part or all of the programs, data, and the like stored in the recording medium 1g are received from the communication control unit 1h from an external device via a communication line such as a WAN (Wide Area Network) or a LAN (Local Area Network). The recording medium 1g may be a recording medium of an external device constructed on a communication line.

Includes providers and base stations.
[0025]
Here, the procedure for displaying the attached image appropriate position will be described with reference to FIGS. FIG. 2 is a flowchart of the attached image appropriate position display program. The CPU 1a on the e-mail display device 1 displays the attached image at an appropriate position by executing the attached image appropriate position display program.
[0026]
This flowchart is for explaining a program for causing the computer constituting the electronic mail display apparatus 1 to realize each function. This program will be described in an example where it is stored in the ROM 1e in the form of a program code readable by the CPU 1a. However, it is not necessary to store all the functions in the ROM 1e, and a part or all of the functions are recorded on the recording medium as necessary. It may be realized by receiving from 1f or from the communication control unit 1h via a communication line. This description is the same for the flowchart of the program executed on the electronic mail display device 1 below.
[0027]
Consider the case where an attached image file exists in the received e-mail before the processing procedure, and an appropriate display position cannot be obtained in the attached image file. The position is set in advance. Then, the CPU 1a on the electronic mail display device 1 receives the electronic mail via the communication line and communication control unit 1h, records it on the recording medium 1g, and stores it on the RAM 1c.
[0028]
First, the CPU 1a extracts and analyzes MIME (Multipurpose Internet Mail Extensions) in the electronic mail on the RAM 1c (step A1). And CPU1a discriminate | determines whether it is a plain text from MIME of the received email (step A2). Specifically, the CPU 1a uses a data identification description (Content-Type) that is a part of the MIME protocol as a field for describing various information of the electronic mail, and indicates that the content is a plain text mail. Type: Judged by whether text / plain exists. The field exists in the header part of the email or the part divided by MIME.
[0029]
If it is plain text (step A2; YES), the CPU 1a determines whether there is an attached image file that can be displayed on the display unit 1d (step A3). Specifically, the CPU 1a identifies data indicating an attached image file such as Content-Type: image / jpeg; indicating a JPEG file or Content-Type: image / gif; indicating a GIF file as the MIME field of the e-mail. Search and determine the description.
[0030]
When there is a displayable attached image file (step A3; YES), the CPU 1a analyzes the inside of the attached image file to obtain the image size of the attached image having the width and height. (Step A4). Then, the CPU 1a reads the body that is the plain text of the received electronic mail (step A5). Then, the CPU 1a creates a row management table (step A6), and the CPU 1a searches for an attached image insertion position (step A7). Steps A6 and A7 will be described in detail later.
[0031]
Next, the CPU 1a determines whether or not the attached image can be inserted (step A8). When the attached image insertion position is obtained in step A7 and the attached image can be inserted (step A8; YES), the CPU 1a sets the display of the attached image at the attached image insertion position searched in step A7 ( Step A9). If the attached image insertion position cannot be obtained in step A7 and the attached image cannot be inserted (step A8; NO), the CPU 1a sets the display of the attached image at a preset default position (step A10). ).
[0032]
Then, the CPU 1a displays the e-mail on the display unit 1d (step A11). Specifically, the CPU 1a first displays the text, and displays the attached image of the attached image file at the attached image insertion position via step A8 and at the default position after step A9. If it is not plain text (step A2; NO), or if there is no displayable attached image file (step A3; NO), the process proceeds to step A11, and the CPU 1a displays the electronic mail on the display unit 1d as usual. This is the end of the attached image appropriate position display procedure.
[0033]
Next, the procedure for creating a row management table at step A6 will be described with reference to FIGS. 3 is a flowchart of the row management table creation program, FIG. 4 is a diagram for explaining the row management table, (I) is a diagram showing an internal configuration of the row management table, and (II) is ( It is a figure which shows the mail text corresponding to I). The line management table stores the line number in the body of the email, the number of leading blank characters for each line number, the number of characters other than the leading blank character, and the line feed position for each line number on the recording medium 1g. .
[0034]
After step A5 is completed, the row management table creation procedure of step A6 is started. First, the CPU 1a acquires one character from the text of the received electronic mail (step B1). First, the first character of the first line of the body is obtained. Then, it is determined whether the acquired one character is a blank character at the beginning of the line (step B2). If it is a leading blank character (step B2; YES), the CPU 1a counts up the number of leading blank characters by one (step B3). And it returns to step B1 and acquires the following 1 character.
[0035]
If it is not a space character at the beginning of the line (step B2; NO), the CPU 1a determines whether the line is a line feed based on whether the acquired character is a line feed character (step B4). If it is not a line feed (step B4; NO), the CPU 1a determines whether or not the maximum number of display characters per line has been exceeded (step B5). Specifically, the maximum displayable total number of characters for each line is acquired as the maximum number of displayable characters per line from the horizontal display size that is the maximum horizontal displayable width set in advance, and the above-mentioned count is performed. Using the number of blank characters at the beginning of the line plus the number of characters as the total number of characters, it is determined whether the total number of characters exceeds the maximum number of display characters per line.
[0036]
When the maximum number of characters displayed per line is not exceeded (step B5; NO), the CPU 1a counts up the number of characters by one (step B6). And it returns to step B1 and acquires the following 1 character. If it is a line break (step B4; YES), the CPU 1a registers “number of characters + number of blank characters at the beginning of line” (total number of characters in the line) +1 as the line break position in the line management table (step B7). If the maximum number of characters displayed per line is exceeded (step B5; YES), the CPU 1a registers 0 in the line management table as a line feed position (step B8). That is, the number of characters and the number of blank characters at the beginning of the line are counted up until the line is folded on the line feed or display area.
[0037]
Then, the CPU 1a registers the counted number of characters in the line management table (step B9), registers the counted number of leading blank characters in the line management table (step B10), and registers a line number in the line management table (step B10). Step B11). In step B11, 1 is initially registered.
[0038]
And CPU1a discriminate | determines whether the character which is not acquired by step B1 exists in the text other than in an email text (step B12). When there is another character (step B12; YES), the CPU 1a counts up the line number (step B13), returns to step B1, and acquires one character of the next line. If there are no other characters (step B12; NO), the row management table creation procedure is terminated and the process proceeds to step A7.
[0039]
Here, a specific example will be described with reference to FIG. If the maximum number of characters displayed per line is 30, and each data of the mail body shown in FIG. 4 (II) is registered, a line management table is created as shown in FIG. 4 (I). At this time, the first line without a line feed position is the beginning of a paragraph, and “0” is recorded at the line feed position in FIG. The second line with the line feed position is the end of the paragraph, and the position “29” where the line feed is designated is recorded at the line feed position in FIG. The third line starts as a paragraph and ends the paragraph in that line.
[0040]
Next, the attached image insertion position search procedure in step A7 will be described with reference to FIG. FIG. 5 is a flowchart of the attached image insertion position search program. First, the CPU 1a reads the row management table on the recording medium 1g created in step A6 (step C1). Then, the CPU 1a calculates the total number of characters from the number of characters of the first row number and the number of leading blank characters in the row management table, calculates the row width of the row with the row number, and stores it in the row management table (step C2). . The line width is the total number of characters in the line of the corresponding line number (number of blank characters at the beginning of the line + number of characters) × character spacing. Then, the CPU 1a determines whether or not the row width has been calculated for all rows (step C3). If the row width of all the rows has not been calculated (step C3; NO), the CPU 1a returns to step C2 to calculate. Calculate and store the line width of the missing line.
[0041]
When the row widths of all rows are calculated (step C3; YES), the CPU 1a subtracts the row width of each row calculated in step C2 from the preset horizontal display size to obtain “horizontal display size” − “ The “line width” is calculated and stored in the line management table (step C4). And CPU1a discriminate | determines whether the horizontal direction display size-row width was calculated about all the lines (step C5). When the horizontal display size-row width is not calculated for all rows (step C5; NO), the process returns to step C4, and the "horizontal display size"-"row width" of the uncalculated rows is calculated. Store in the row management table.
[0042]
When “horizontal display size” − “row width” is calculated for all rows (step C5; YES), the CPU 1a determines the horizontal width from the “horizontal display size” — “row width” of all stored rows. It is determined whether there is a line into which the attached image file can be inserted (step C6). Specifically, it is determined whether or not there is a row where “horizontal display size” − “row width” exceeds the horizontal width of the image size of the attached image acquired in step A4. When there is a row in which an attached image can be inserted for the horizontal width (step C6; YES), the CPU 1a extracts a row in which the attached image can be inserted for the horizontal width (step C7). And CPU1a discriminate | determines whether the position which can insert the said attachment image about height exists from the line extracted by step C7 (step C8). Specifically, continuous insertable lines extracted in step C7 are extracted, and the total height of the continuous lines exceeds the height of the image size of the attached image acquired in step A4. Determine if the row exists. If there are no consecutive lines, a single line is extracted and determined.
[0043]
When there is no position where the attached image can be inserted with respect to the height (step C8; NO), the CPU 1a adds a blank height for one line to the total height of the continuous lines (step C9). Then, the process returns to step C8, and it is determined whether or not there is a position where the attached image can be inserted with respect to the total height of the continuous lines added. In step C9, a blank space height may be added in place of blank line addition.
[0044]
When there is a position where the attached image can be inserted for the height (step C8; YES), the CPU 1a extracts a position where the attached image can be inserted for the height (step C10). Then, the attachment image insertion position is determined from the position extracted in step C10 (step C11). The attached image insertion in the horizontal direction may be displayed from the right end regardless of the position of the line feed character, or may be set to be displayed at the line feed position. If there are several attachment image insertion positions in step C11, the user on the e-mail display device 1 may select the position, or the user may preferentially select from the upper line, and the largest available space. An area may be preferentially selected.
[0045]
If there is no row in which the attached image can be inserted for the horizontal width (step C6; NO), the attached image insertion position for inserting the attached image is not set. Then, the procedure for searching for the attached image insertion position is terminated, and the process proceeds to Step A8.
[0046]
Here, a specific example will be described with reference to FIG. In FIG. 4 (II), the maximum number of characters displayed in the horizontal direction is 30 characters, and the character spacing is 16 dots, so the horizontal display size is 480 dots. At this time, as shown in FIG. 4I, the row width and the value of “horizontal display size” − “row width” are calculated. In the horizontal empty area indicated by “horizontal display size” − “line width”, the first line having no line feed position is zero.
[0047]
In addition, a display example of the present embodiment will be described in comparison with a conventional example with reference to FIG. FIG. 6 is a diagram showing display results of a conventional example and an attached image appropriate position display procedure, (I) is a diagram showing a conventional display screen, and (II) is an attached image appropriate position display procedure. It is a figure which shows a display screen. In FIG. 6 (II), unlike the conventional example, it is possible to insert the attached image of the attached image file from the second line to the sixth line in the horizontal direction, and the height from the second line to the sixth line. The attached image is displayed at the right end by adding a blank line to the total height of.
[0048]
As a modification of the present embodiment, if the maximum free area of the e-mail body is less than the image size of the attached image of the attached image file in step C7, the attached image is included in the maximum free area. It may be reduced and displayed.
[0049]
Further, in the same procedure as steps C1 to C11, as in steps C4 and C5, the head blank character widths of all the rows are calculated from the number of head blank characters in the row management table and stored in the recording medium 1g. As in steps C6 and C7, a line that can be inserted into the leading blank width is extracted for the horizontal width, and a position that can be inserted for height is extracted from the extracted lines in the same manner as in steps C8, C9, and C10. Thus, a configuration may be adopted in which the attachment image insertion position is determined as in C11. For example, in step A8, determination is made based on whether there is an attached image insertion position using the horizontal display size-line width and an attached image insertion position using the leading blank character width. In addition, when there are several attachment image insertion positions in step A8, the user on the electronic mail display device 1 may select it, or it may be selected preferentially from the upper line, and the largest available space. An area may be preferentially selected.
[0050]
Therefore, according to the present embodiment, since the plain text of the mail body is analyzed using MIME without using a page description language such as HTML, an area where the attached image can be displayed is appropriately extracted. Processing and setting for displaying an image on an e-mail display device can be simplified by lowering technical hurdles, and an attached image can be displayed in an empty area of text, so that the display area can be effectively used.
[0051]
(Second Embodiment)
This embodiment will be described with reference to FIGS. Similar to the first embodiment, using the electronic mail display device 1, the CPU 1 a displays the attached image at an appropriate position determined by the total number of lines of the electronic mail body by executing the sentence end attached image insertion program. Let FIG. 7 is a flowchart of the end-of-sentence attached image display program.
[0052]
First, after receiving an e-mail via the communication line and the communication control unit 1h, a sentence end attached image display procedure is started by executing a sentence end attached image insertion program. It is not necessary to set the default position. Steps D1 to D5 are the same as steps A1 to A3 and A5 to A6, respectively. Next, the CPU 1a acquires the number of lines in the read text from the line number in the line management table created in step D5 and stores it on the recording medium 1g (step D6). Then, the CPU 1a determines whether or not the number of lines acquired in step D6 is larger than a predetermined number of lines that is predetermined (step D7). When it is larger than the prescribed number of lines (step D7; YES), the CPU 1a sets the attached image insertion position at the head of the e-mail body (step D8). When it is not larger than the specified number of lines (step D7; NO), the CPU 1a sets the attached image insertion position at the end of the text (step D9).
[0053]
Then, the CPU 1a displays the electronic mail on the display unit 1d (step D10). Specifically, the CPU 1a first displays the text, and when the process passes through step D8 or D9, displays the attached image of the attached image file at the attached image insertion position. If it is not plain text (step D2; NO), or if there is no displayable attached image file (step D3; NO), the process proceeds to step D10, and the CPU 1a causes the display unit 1d to display the electronic mail as usual. . This is the end of the sentence end attached image display procedure.
[0054]
Here, with reference to FIG. 8, the display example of this Embodiment is compared and demonstrated by the total number of lines. FIG. 8 is a diagram showing a display result according to the end-of-sentence attached image display procedure, (I) is a diagram showing a display screen when the total number of lines is not larger than the specified number of lines, and (II) is It is a figure which shows a display screen in case it is larger than the regulation number of lines. In (I), since there are few lines, the attached image of the attached image file is displayed at the end of the body of the e-mail. In (II), since there are many lines, the attached image is displayed at the beginning of the body of the e-mail.
[0055]
Therefore, according to the present embodiment, in the case of a long sentence, the attached image of the attached image file is displayed at the beginning of the sentence, so there is no need to scroll the sentence to the attached image display position, and the mail recipient Can see the image immediately.
[0056]
(Third embodiment)
This embodiment will be described with reference to FIGS. As in the first embodiment, using the electronic mail display device 1, the CPU 1a executes the default word / phrase attached image insertion program to determine the attached image of the attached image file based on the default word / phrase in the body of the email. Display at the correct position. FIG. 9 is a flowchart of the default phrase attached image display program.
[0057]
First, after receiving an e-mail via the communication line and communication control unit 1h, a default word / phrase attached image display procedure is started by executing a default word / phrase attached image insertion program. As in the first embodiment, the default position is set in advance. Steps E1 to E5 are the same as steps A1 to A3 and A5 to A6, respectively.
[0058]
Then, the CPU 1a reads a predetermined word / phrase from the ROM 1e (step E6). The default phrase is, for example, a phrase that is equivalent to an attached image file such as “picture”, “image”, “photo”, “map”, and the like. A default phrase table for registering these default phrases in the ROM 1e is stored in advance, and the default phrases on the default phrase table are read out in this procedure. Alternatively, the default phrase may be stored in the recording medium 1g, and the default phrase may be read from the recording medium 1g in step E6 as a configuration that can be changed as needed. Then, the CPU 1a extracts the attached image file name from the MIME field of the e-mail extracted at step E1 (step E7).
[0059]
Then, the CPU 1a determines whether or not the read default word / phrase is included in the read attached image file name (step E8). If the default word / phrase is included (step E8; YES), the CPU 1a searches for the corresponding default word / phrase in the text of the e-mail (step E9). When the default phrase is not included (step E9; NO), the CPU 1a searches the attached image file name in the text (step E10).
[0060]
Then, the CPU 1a determines whether or not the default phrase or the attached image file name can be retrieved as the target phrase in step E9 or E10 (step E11). If the search is successful (step E11; YES), an attached image insertion position is set after the paragraph in which the target word / phrase exists (step E12). Specifically, the CPU 1a uses the line management table created in step E5 to determine whether the line feed position of the line in which the target word is present is a value other than 0. The first line whose line break position is a value other than 0 is taken as the last line of the paragraph having the target word and the next line after the last line of the paragraph is an attached image. Set as insertion position.
[0061]
When there is no target word / phrase (step E11; NO), the CPU 1a sets the display position of the attached image file to a predetermined default position.
[0062]
Then, the CPU 1a displays the electronic mail on the display unit 1d (step E14). Specifically, the CPU 1a first displays the text, and displays the attached image of the attached image file at the attached image insertion position when it passes through step E12 and at the default position when it passes through step E13. .

Therefore, according to the present embodiment, the attached image of the attached image file can be displayed at a position related to the content of the text.
[0066]
(Fourth embodiment)
This embodiment will be described with reference to FIGS. Similar to the first embodiment, using the electronic mail display device 1, the CPU 1a executes the keyword attached image insertion program to display the attached image of the attached image file at a position corresponding to the keyword of the electronic mail text. . FIG. 11 is a flowchart of the keyword-attached image display program.
[0067]
First, the default position is set in advance as in the first embodiment. The keyword is a word that can be recognized between the sending side and the receiving side of the e-mail and is set in advance on the sending side and the receiving side to insert and display the attached image of the attached image file. For example, “$ ATTACHMENT_1” $ ","& IMAGE_INS2 ", etc.
[0068]
First, after receiving an electronic mail via the communication line and communication control unit 1h, a keyword attached image display procedure is started by executing a keyword attached image insertion program. Steps F1 to F5 are the same as steps A1 to A3 and A5 to A6, respectively.
[0069]
Next, the CPU 1a reads a keyword from the ROM 1e (step F6). A keyword table for registering these keywords is stored in the ROM 1e, and the keywords on the keyword table are read out in this procedure. Further, the keyword may be stored in the recording medium 1g, and the keyword may be read from the recording medium 1g in step F6 as a configuration that can be changed as needed. Then, the CPU 1a searches for the read keyword from the text of the e-mail (step F7).
[0070]
Then, the CPU 1a determines whether or not the read keyword is included in the text (step F8). If a keyword is included (step F8; YES), the CPU 1a sets the attached image insertion position in a line with the corresponding keyword (step F9). Specifically, the CPU 1a searches for a line in which the keyword exists using the line management table created in step F5, and sets the line having the keyword as an attached image insertion position. And since it is not necessary to display a keyword, CPU1a deletes the keyword in a text (step F10). When the keyword is not included (step F8; NO), the CPU 1a sets the display position of the attached image file to a predetermined default position (step F11).
[0071]
Then, the CPU 1a displays the electronic mail on the display unit 1d (step F12). Specifically, the CPU 1a first displays the text, and displays the attached image of the attached image file at the attached image insertion position when it passes through step F9 and at the default position when it passes through step F11. . If it is not plain text (step F2; NO), or if there is no displayable attached image file (step F3; NO), the process proceeds to step F12, and the CPU 1a displays the e-mail on the display unit 1d as usual. Let This completes the keyword-attached image display procedure.
[0072]
Here, a display example of the keyword-attached image display procedure will be described in comparison with the conventional example with reference to FIG. FIG. 12 is a diagram showing the display results of the conventional example and the keyword-attached image insertion display example. (I) is a conventional display screen, and (II) is a display screen according to the keyword-attached image insertion display procedure. is there. In FIG. 12 (II), an attached image is displayed on a line including the keyword $ ATTACHMENT_1 $.
[0073]
As an application example, on the mail receiving side, the keyword display position is further changed by the user's convenience from the keyword attached image insertion position specified by the sender, and the attached image of the attached image file is displayed at a desired position. It is good also as a structure.
[0074]
Therefore, according to the present embodiment, since the attached image of the attached image file is displayed at the location where the keyword is set in advance, the attached image is displayed at the most appropriate position at the time of mail transmission. Can be specified to be displayed. Further, according to the above application example, the mail receiving side can further change the display position of the keyword at his convenience and display the attached image at a desired position.
[0075]
