Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a document processing device,
In particular, the present invention relates to a case in which characters such as characters and symbols that have been input are displayed as a print image, and only characters that are legible by character modification are displayed as modified characters.

[0002]

2. Description of the Related Art Conventionally, a Japanese or English word processor is basically provided with a display capable of displaying document data for a plurality of lines, a keyboard, a printing mechanism having a dot-printing print head, and the like. Document data consisting of input characters and symbols is displayed in a matrix on the display with a predetermined character size, and when a print process is instructed for the input document data, the print character size, character pitch, and line spacing are included in advance. The document data can be printed on a printing paper based on the set format information. By the way, recent word processors have been put into practical use that have an image display function of displaying a print image of the document in addition to a layout display function of displaying a layout of input document data.

That is, when a print image of document data is displayed by this image display function, characters such as characters and symbols of the document data have a display character size corresponding to the set print character size, and the set character spacing is set. It is displayed on the display based on the pitch and line spacing. By the way, when character modification instructions such as white characters (outline characters), bold characters, and shaded white characters are given to any characters or symbols in this document data, the characters or symbols that have been given the character modification instructions are A print image is displayed on the display with a modified character according to the type of the character modification.

[0004]

As described above, in the word processor having the image display function, the characters and symbols in the document data for which character modification is instructed are displayed characters corresponding to the set print character size. Since the print image is displayed with the modified characters according to the type of character modification depending on the size, especially when the printed character size is small, the displayed character size is also small. Regarding the modified characters, there is a problem that the characters are not blank and the characters and symbols are difficult to read.

It is an object of the present invention to provide a document processing apparatus capable of selectively displaying only legible modified characters suitable for displaying a print image and enhancing the image display function.

[0006]

A document processing apparatus according to a first aspect of the present invention, as shown in the functional block diagram of FIG. 1, has input means for inputting characters such as characters and symbols and various commands. A data storage means for storing character data input from the input means, a font storage means for storing display dot pattern data relating to the character, and a character decoration for setting the type of character decoration applied to the character printed out by the printing means. With respect to the data of the setting means and the data storage means, the display dot pattern data is read from the font storage means, and the display modified dot image data of a plurality of characters subjected to the character modification of the type set by the character modification setting means is created. Display dot image creating means, and display dot image creating means from the display dot image creating means. In a document processing apparatus including display means for receiving data and displaying it on a display, and printing means for printing characters stored in the data storage means on a print medium, and data of a modification type set by the character modification setting means, Based on the display character size determined in correspondence with the character size to be printed and the predetermined discrimination logic set in advance, it is determined for each character whether or not the character-modified character is unreadable on the display. When the character-modified character is unreadable when receiving the output from the character-modification possibility determining means for determining and the character-modification possibility determining means, the display-modified dot-image data of the character is displayed in the display-dot-image creating means. And a character decoration display stop command means for stopping the creation.

[0007]

In the document processing apparatus according to the first aspect, when the character decoration setting means sets the character decoration type to be applied to the character printed out by the printing means, the display dot image forming means is the data storage means. For the character data stored in, the display dot pattern data relating to the character is sequentially read from the font storage means, and the modified dot image data for display of a plurality of characters subjected to the character modification of the type set by the character modification setting means is displayed. create. By the way, the character decoration adequacy determining means uses the data of the type of decoration set by the character decoration setting means, the display character size determined in association with the character size to be printed, and the predetermined determination logic set in advance. Based on this, it is determined for each character whether or not the character-modified character is unreadable on the display.The character-modification display stop command means receives the output from the character-modification permission / inhibition judgment means and performs character modification. When the character is unreadable, the display dot image creating means is caused to stop the creation of the display modified dot image data of the character.

As described above, when the display modification dot pattern data for which the set character modification is applied is created for the display dot pattern data of characters such as characters and symbols, the display character size and the preset predetermined value are set. Based on the discrimination logic of the above, it is determined whether the character with the character modification is unreadable on the display, and the character that does not receive the command to stop the creation of the display modified dot pattern data according to the judgment result. Creates the display modification dot pattern data in which the character display dot pattern data is character-modified, while the character for which the command to stop the creation is received is not displayed in the character display dot. Since the pattern data is created, the display will show While displayed through character, only the selectively displaying appropriate legible modified character as a print image display, it is possible to enrich the image display function.

The arrangement position information memory 64 stores the display position information in the display data buffer 65 of each character or symbol to be displayed. The display data buffer 65 stores the input dot pattern data for display of a plurality of characters and symbols, and the print data buffer 66 stores the print dot pattern data of a plurality of characters and symbols for printing. Are combined and stored as dot image data for printing. In addition, a work memory 67 is provided.

Next, the tape print control routine executed by the controller C of the tape printer 1 will be described with reference to the flow charts of FIGS. Incidentally, reference numeral S in the figure
i (i = 10, 11, 12, ...) Is each step. When the power is turned on by the power key on the keyboard 3, this control is started.
.. to 66 are cleared, and an initialization process for initializing the printing mechanism PM is executed (S10). Next, standard format information data is stored in the first 2 bytes of the text memory 61, a document input screen is displayed on the display 22, and this input screen corresponds to the print character size of the standard format information. The cursor K having the size of the display character size is displayed (S11). For example, as shown in FIG. 10, in the first 2 bytes of the text memory 61,
"0 (no modification)" as data MD of character modification number,
“Mincho typeface” is stored as the typeface number data FN, and “44 pt (points)” is stored as the print character size SZ as standard format information.

Next, a print image display process for displaying the characters and symbols stored in the text memory 61 as a print image is executed (S12). This print image display processing will be described later for convenience of description. And
When the format key is operated (S13 / S14: Yes
), The format information setting process control is executed (S17), S12.
After that, the process proceeds to S13. In this format information setting process control, a format setting screen in which the format setting contents such as character decoration type name, print character size and typeface name can be collectively set is displayed on the display 22. Therefore, the cursor movement key is operated. Then, move the cursor to the setting item “Type of character decoration type”, “Print character size name” or “Typeface name”, enter the number key corresponding to the desired setting content, and then press the Enter key. Format information including the data of the character modification number MD and the print character size SZ set by is stored in the text memory 61 as the modified format information.

Here, as types of character modification and setting numbers thereof, 0: no modification, 1: underline, 2: shaded character, 3: bold, 4: italic, 5: outline (white character), 6 : Shadow characters ... can be set. Further, the print character size and its setting number are 1: 6pt, 2: 10pt, 3: 13pt, and 4: 1.
9pt, 5: 26pt, 6: 38pt, and 7: 44pt can be set. For example, as shown in FIG.
By the time the document data is input, when the character modification number MD is changed to "5 (outline)" and the print character size SZ is changed to "19pt", the change format information including the changed setting information is changed to the text memory. 61
In, the data is stored in 2 bytes following the standard format information.

Next, when a printable key such as an alphabetic character key, a symbol key, or a numeric key is operated (S13: Yes, S14: No, S15: Yes), the code data of the operated printable key is documented. Document data storage processing for storing the data in the text memory 61 is executed (S18), and print image display processing control is executed (S18).
12). Next, the print image display processing control will be described (see FIG. 7). At this time, in the text memory 61, as shown in FIG. 10, standard format information, first modified format information, characters “ABCDEF”, line feed code, second modified format information, ... Are sequentially stored. And

When this control is started, first the data in the text memory 61 is sequentially searched from the top address,
Based on the format information, the character code, and the line feed code, the arrangement position information for expanding the display dot pattern data into the display data buffer 65 is obtained for each of the characters and symbols to be displayed, and the arrangement position information is the arrangement position. It is stored in the information memory 64 (S30). Note that the arrangement position information is, for example, the character arrangement position at the time of printing is obtained from the format information, the character code, the line feed code, and the dot pattern data for printing, and the coordinate value is multiplied by 1/3 to obtain the arrangement position for display. Be asked to do so. Next, an initialization process for initializing the parameter information regarding the printing process in the parameter memory 62 is executed (S31). That is, in the parameter memory 62, the start address of the text memory 61 is set to the start address pointer value SP (see FIG. 10), and the end address pointer value EP is set to the address next to the end address of the text memory 61 (end address + 2 ) Is set (see FIG. 10), the initial value "0" is set as the data count value DC, and "0" is set as the character decoration number MD.
(No modification) "is set, and the print character size SZ
"44pt" is set as.

Next, since the format information data and the character code each have a 2-byte structure, the search address data obtained by adding the doubled data count value DC to the start address is read (S32). If is data of format information (S33: Yes), format change processing control (see FIG. 8) is executed (S35). When this control is started, first, the print character size data YSZ stored in the format information is read (S42), and when the print character size SZ in the parameter memory 62 is different from the read print character size YSZ ( (S43: No), the print character size SZ of the parameter memory 62 is changed to the read print character size YSZ (S44). When the print character size SZ is equal to the read print character size YSZ (S43: Yes), the process proceeds to S45.

Next, the character modification number data YMD stored in the format information is read (S45), and when the character modification number MD in the parameter memory 62 and the read character modification number data YMD are different (S46: No), the character modification number MD of the parameter memory 62 is changed to the read character modification number YMD (S47). When the character modification number MD is equal to the read character modification number YMD (S46: Yes), the process proceeds to S48. Next, similarly, the other format information is searched in the same manner, and when there is a change, the changed data is updated and stored (S4
8) Then, this control is terminated, and the process returns to S37 of the print image display processing control.

Next, in the print image display processing control, the data count value DC is incremented by 1 (S37), and the start address pointer value (start address) S
When the search address obtained by adding the address obtained by doubling the data count value DC to P does not match the address designated by the end address pointer value EP and there is a character to be displayed in the text memory 61 (S38: No). ), S32
The subsequent steps are repeatedly executed. When the search address data has a printable character code (S33: No,
S34: Yes), and display image generation processing control (see FIG. 9) is executed (S36).

When this control is started, first, based on the character size conversion table TB1, the display character size corresponding to the print character size SZ in the parameter memory 62 is read (S50), and the display character size and the display character size are read. A display C that stores dot pattern data of a series of characters and symbols of the display character size based on the search table
The index address of GROM 53 is read (S5
1) Further, based on the index address, the display character index table and the character code, the storage start address of the character code in the display CGROM 53, that is, the font storage address is read (S52) and stored in the font storage address. The display dot pattern data is read from the display CGROM 53 and temporarily stored in the work memory 67 (S53).

Next, if the character modification number MD is not "0",
When the character modification processing is executed (S54: No), it is determined whether or not the character modification processing is possible based on the type of character modification, the display character size, and the predetermined determination logic (S55). As a result, when character modification display is possible (S
56: No), the character modification processing of the modification type indicated by the character modification number MD is executed for the character, and the display modified dot pattern data subjected to the character modification processing is updated and stored in the work memory 67. (S57) and S58 are entered. Here, as a result of the determination, when the character modification display is impossible (S56: Yes) or when it is determined Yes in S54, the process proceeds to S58 without creating the modification dot pattern data for display of the character. To do. The dot pattern data stored in the work memory 67 is instructed by the layout position data of the character stored in the layout position information memory 64.
It is stored in the storage position of 5 (S58), this control is ended, and the process returns to S37 of the print image display processing control.

Here, the above-mentioned predetermined discrimination logic will be described. For example, for the "shadow character" of the character modification type number "2", the print character size SZ is 13pt or more and the character modification display of the shadow character is performed. For "bold" with character modification type number "3", it is possible to display bold character modification with print character size SZ of 6pt or more, and for "outline" with character modification type number "5" The outline character modification display is possible when the print character size SZ is 13pt or more. Furthermore, regarding the "shadow character" of the character modification type number "6", the character modification display of the shadow character is possible when the print character size SZ is 26pt or more. It is logically made possible.

Next, in the print image display processing control, after S37 is executed, the search address obtained by adding the address obtained by doubling the data count value DC to the start address matches the address designated by the end address pointer value EP. If so (S38: Yes), the display data buffer 65
The dot image data for display which is expanded and stored in is stored in the video RAM 24 and is displayed on the display 22 (S39).
Return to 13.

For example, when the format information and the character code string shown in FIG. 10 are stored in the text memory 61, the character modification type is set to "outline" for the character strings "A to F". Since "19pt" is set as the print character size SZ, the character decoration display can be performed by the above-described discrimination logic. Therefore, as shown in FIG. 11, for these character strings "A to F", "outline" is displayed. It is displayed on the display 22 with characters modified,
Character string "A to F" with character modification of "outline"
Can be reliably read on the display 22.
On the other hand, regarding the character strings “H to J” and “K to M” for two lines, the type of character decoration is set to “outline”, but “10 pt” is set as the print character size SZ. Therefore, since the character decoration display is impossible by the above-mentioned discrimination logic, as shown in FIG.
“J” and “K to M” are displayed on the display 22 as normal characters without character modification of “outline”.

By the way, for example, the text memory 61
In the case where the format information and the character code string shown in FIG. 12 are stored in, the character strings “A to F” and “H to M” for two lines are stored.
Is "outline" and the print character size S
Since Z is "19pt", the character decoration display can be performed by the above-mentioned discrimination logic. Therefore, as shown in FIG. 13, for these two lines of character strings "A to F" and "HM",
Display 22 with "Outline"
The character strings “A to F” and “H to M” that are displayed on the display 22 and are subjected to the character modification of “outline” can be reliably read on the display 22.

Next, in the tape print control, when the print key is operated (S13: Yes, S14 to S15: No,
S16: Yes), print processing control is executed (S19), S12
Return to. Since this print processing control is similar to the normal print processing, it will be briefly described. Format information and character codes are sequentially read from the text memory 61, and the character codes are printed based on the print character search table and the print character index table. The dot pattern data for printing in the CGROM 54 for printing is read out, expanded in the print data buffer 66, combined and stored, and the dot image data for printing in this print data buffer 66 is output to the printing mechanism PM,
It is printed on the printing tape 19. By the way, when a key other than the format setting key, the printable key, and the print key is operated (S13: Yes, S14 to S16: No), the process corresponding to the operated key is executed (S20) and S12 is executed. Return.

As described above, with respect to the display dot pattern data for displaying characters such as characters and symbols, when the display modification dot pattern data subjected to the set character modification is created, the type of the character modification and the display character are displayed. Based on the size and a predetermined determination logic set in advance, it is determined whether the character-modified character is unreadable on the display 22, and the display modification dot pattern data is created based on the determination result. For characters that do not receive a command to cancel, character modification is applied to the display dot pattern data of the character to create display modification dot pattern data, while for characters that receive the command to cancel creation, character modification is performed. Since the dot pattern data for displaying the character itself is created without it, the display 22 While displaying ordinary characters for Unreadable modified character, only the selectively displaying appropriate legible modified character as a print image display, it is possible to enrich the image display function.

Here, the correspondence between each means described in the claims and the configuration in the above-mentioned embodiment will be explained. The means corresponding to the character modification adequacy determining means is particularly related to the display image generation processing control. S54 to S55, which correspond to the character decoration display stop command means, are S56: Yes and S58.
Is.

The above-mentioned discrimination logic for discriminating whether or not character modification is possible is an example, and the display 22
It is possible to appropriately change it according to the size of the display screen, the number of dots forming the display dot pattern data, and the like. The print character size may be calculated from the tape width of the print tape 19 and the number of lines of the input document. It should be noted that, within the scope of the technical idea of the present invention, various modifications may be made to the control of the above-described embodiment based on existing technology or technology obvious to those skilled in the art. It is needless to say that the present invention can be applied to various document processing devices such as a word processor having a keyboard, a display, and a printing device and capable of character modification processing.

[0041]

According to the document processing apparatus of the first aspect,
When the character modification permission / inhibition determination means and the character modification display stop command means are provided to create the display modification dot pattern data with the set character modification for the display dot pattern data of characters such as characters and symbols. , Based on the type of character decoration, display character size, and predetermined decision logic, it is determined whether the character with the character decoration is unreadable on the display. For characters that do not receive the command to stop the creation of the modified dot pattern data, create the modified dot pattern data for display by character-modifying the dot pattern data for display of the character, while receiving the command to stop the creation. For, the dot pattern data for display of the character itself is created without character modification. The display displays normal characters for unreadable modified characters, while selectively displaying only readable modified characters suitable for print image display, thus enhancing the image display function. .
