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,
Particularly, when the input character is displayed in a print image, the present invention relates to a display in which a dummy display is once made in the original form until the display dot pattern data is created.

[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 print sheet based on the set print format (format information). by the way,
Recently, word processors having a layout display function for displaying a layout of input document data and an image display function for displaying a print image of the document have been put into practical use.

That is, when the print image display mode is set instead of the normal document data display mode and the print image of the document data is displayed by this image display function,
Characters such as characters and symbols in the document data are displayed as an image corresponding to the print character size and typeface set in the print format, and if the print format is set to have character modification, the modification type is used. It is modified and displayed on the display based on the set inter-character pitch and inter-line value. When the document data is edited, the print image display mode is released, the document data display mode is switched to the normal document data display mode, and the character string is edited or changed.

By the way, in a tape printer, which is one type of document processing device, characters such as characters and symbols are printed on a tape as a print medium, and a label suitable for being attached to the spine of a file is created. In the case of a tape printing apparatus suitable for printing, a print image display method is used in order to create document data while setting various print formats through a small display and checking the print image on the display. It is not uncommon to set a print format or input or edit document data while displaying in. Here, in the print format,
When not only the print character size and typeface to be printed out but also the type of modification for character modification is set, the display dot pattern corresponding to the set print character size and typeface is entered each time a character is input. After the data is modified, the modified display dot pattern data is displayed at the input position on the display.

[0005]

As described above, in the tape printer having the image display function, when the data of the document is input while the print format is set and the print image is displayed. For the input characters, the display dot pattern data corresponding to the print character size and typeface set in the print format is modified by the specified character modification, and then the modified display dot pattern data Appears on the display, so it takes time from the key input to the character display. Particularly, in the case of a complicated modification process such as outline modification, since the modification process requires time, the display process of the character is delayed.
If the user waits for key input until the display is completed, there is a problem that key input work is delayed. Also, if key input is performed before the display processing is completed, the operator cannot confirm that the character input has been made surely due to the display delay, and the character is wasted as if it was not input. No characters were input or characters were not input, resulting in missing characters.

It is an object of the present invention to provide a document processing apparatus in which an input character is temporarily dummy-displayed in its original form prior to image display so that display processing and key input processing in image display can be speeded up. is there.

Next, standard print format information data is stored in the first 2 bytes of the text memory 61 (S11), and the display 22 displays a print image display screen for displaying the input characters in a print image similar to the print state. At the same time, a vertical bar cursor K having a display character size corresponding to the print character size of the standard print format information is displayed on this display screen (S12).

For example, as shown in FIG. 10, in the first 2 bytes of the text memory 61, "0 (no modification)" is set as the character modification number data MS, "Mincho typeface" is printed as the typeface number data FN, and printed. As the character size SZ, "44p
t (point) ", the maximum printable length" MAX "as the set tape length, and" 0 "as the even allocation flag WF.
(No setting) ”is stored as the standard print 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 (S13), the dummy display flag DF is reset (S14), and the process proceeds to S15. This print image display processing will be described later for convenience of description.
When the print format setting key is operated (S15 / S16: Yes), the print format information setting process control is executed (S22), and the process proceeds to S15 via S13 / S14. In this print format information setting processing control, a print format setting screen on which the print format setting contents relating to the type name of character decoration, print character size, typeface name, set tape length, even allocation, etc. can be collectively set is displayed. Is displayed, move the cursor K to the setting item "Type of character decoration type", "Print character size name", "Type name" ... When the execute key is operated after inputting the numeric key corresponding to, the print format information including the character modification number MS and the print character size SZ set by the number is stored in the text memory 61 as the changed print format information. To be done.

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.
When the character modification number MS is changed to “5 (outline)” by the time the document data is input, the changed print format information including the changed setting information is
In the text memory 61, 2 bytes are stored following the standard print format information.

Next, when a printable key such as an alphabetic character key, a symbol key, or a numeric key is operated (S15: Yes, S16: No, S17: Yes), the code data of the operated printable key is written. Document data storage processing for storing the data in the text memory 61 as data is executed (S23), and the dummy display flag DF is set (S2).
4), the dummy display data creation processing control (see FIG. 7) is executed (S25). Here, in the document data storage processing, the cursor pointer value CP is sequentially incremented by 2 bytes each time a character is input.

When this control is started, first, based on the data of the character size conversion table TB1 and the data of the latest print format information stored in the text memory 61, the display character corresponding to the print character size SZ is displayed. Size is required (S30). Then, based on this display character size, "Mincho typeface" which is a predetermined typeface, and the display character search table, a display CG in which dot pattern data of a series of characters and symbols of the display character size is stored.
The index address of the ROM 53 is read, and based on the index address, the display character index table and the character code, the C for displaying the character code is displayed.
The storage start address in the GROM 53, that is, the font storage address is read, and the display dot pattern data stored at the font storage address is displayed as C for display.
It is read from the GROM 53 and temporarily stored in the work memory as dummy display data (S31).

Next, the dummy display data of the work memory is stored in the display data buffer 66 by overwriting the already stored display dot image data (S32) and expanded in the display data buffer 66. The stored one-screen display dot image data is output to the video RAM 24 (S33), the cursor display processing control is further executed (S34), the control is ended, and the process returns to S15 of the tape printing control. In this cursor display processing control, cursor display data for the vertical bar-shaped cursor K is created and output to the video RAM 24.
The cursor K is displayed at the left end of the predetermined display position on the display 22 corresponding to the cursor pointer value CP.

For example, in the text memory 61, FIG.
As shown in, when the input character “U” is stored,
Print character size SZ “44” of changed print format information
Based on "pt", the display character size is 32 dots and the dot pattern data for display of "Mincho typeface" is created as dummy display data. As shown in FIG. The character "U" is displayed as a dummy, and the cursor K is displayed at the left end of the display position on the right side.

In the tape print control, when printable keys are sequentially input (S15: Yes, S16:
No, S17: Yes), but S23 to S25 are similarly repeated, but when various function keys other than the printable key are operated (S15: Yes, S16 / S17: No),
When the dummy display flag DF is set (S18:
Yes), or when there is no key operation such as a printable key or a function key (S15: No), and when the dummy display flag DF is set (S21: Yes), the print image display processing control is executed (S15: No). S13). Next, the print image display processing control will be described with reference to FIG.

When this control is started, first, the data in the text memory 61 is sequentially searched from the head address,
Based on the print 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 66 is obtained for each of the characters and symbols to be displayed, and the arrangement position information is arranged. It is stored in the position information memory 65 (S40). The arrangement position information is, for example, the character arrangement position at the time of printing is obtained from the print format information, the character code, the line feed code, and the printing dot pattern data, and the coordinate value is multiplied by ⅓ to the arrangement position for display. And the like.

Next, an initialization process for initializing the print format information regarding the print process in the print parameter memory 62 is executed (S41). That is, in the print parameter memory 62, the start address pointer value SP is set to the start address of the text memory 61 (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, "44pt" is set as the print character size SZ, and the character modification number MS
Is set to "0 (no modification)", the even allocation flag WF is set to "0 (no setting)", the typeface is set to "Mincho typeface", and the set tape length is set to "MAX". .

Next, since the data of the print format information and the character code are each composed of 2 bytes, the data of the retrieval address obtained by adding the address obtained by doubling the data count value DC to the head address is read (S42). When the data is print format information data (S
43: Yes), and the print format information change processing control for storing the print character size SZ and the character decoration number MS of the print format information in the print parameter memory 62 is executed (S45).

Next, the data count value DC is incremented by 1 (S47), and the search address and the end address pointer value obtained by adding the address obtained by doubling the data count value DC to the start address pointer value (start address) SP If the address designated by the EP does not match and there is a character to be displayed in the text memory 61 (S4
8: No), S42 and subsequent steps are repeatedly executed. And
When the data of the search address is a printable character code (S43: No, S44: Yes), the display image generation processing control (see FIG. 9) is executed (S46).

When this control is started, first, the print parameter memory 6 is generated based on the character size conversion table TB1.
The display character size corresponding to the print character size SZ in 2 is read and stored in the display character size memory 64 (S6
0), based on the display character size and the display character search table, a display CGROM storing dot pattern data of a series of characters and symbols of the display character size.
The index address of 53 is read (S61), and 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 (S62), The display dot pattern data stored in the font storage address is read from the display CGROM 53 and temporarily stored in the work memory (S63).

Next, the character modification number MS is not "0",
When the character modification process is executed (S64: No), the character modification process designated by the character modification number MS is executed for the character, and the modified display dot pattern data is updated and stored in the work memory. (S6
Five). Further, when the even allocation flag WF is set (S66: Yes), the even allocation processing for evenly allocating the input character to the set tape length is executed,
The display dot pattern data subjected to the equal allocation processing is updated and stored in the work memory (S67). Briefly explaining the equal allocation process, the remaining tape length obtained by subtracting the character widths of all the characters of the document data from the set tape length is divided by the number of characters to determine the even allocation position of each character. Desired.

Next, the new display dot pattern data stored in the work memory and subjected to the character modification processing and the uniform allocation processing overwrites the display dot pattern data including the dummy display data in the display data buffer 66. And stored in a predetermined storage location (S68),
After ending this control, S47 of the print image display processing control
Return to. Here, when the character modification number MS is "0" and the even allocation flag WF is not set (S64: Yes, S66: No), the dot pattern for display in the work memory is not subjected to any of these processes. The data is stored in a predetermined storage position of the display data buffer 66 (S68).

Next, in the print image display processing control, after S47 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 (S48: Yes), the display data buffer 66
The display dot image data for one screen, which is expanded and stored in, is output to the video RAM 24 and displayed on the display 22 (S49), and the cursor display processing is further executed as described above (S50). Exit
The process returns to S14 of tape print control.

For example, in the text memory 61, as shown in FIG. 10, the print format information and the character code "U" are displayed.
Is stored in the print character size SZ for the character “U” based on the changed print format information.
"44pt" as the typeface, "Mincho typeface" as the typeface, and "outline" as the type of character decoration,
As shown in FIG. 12, the character “U” is displayed on the display 22 as a modified character of the outline based on the print format information, and the cursor K is displayed at the next display position. Further, as shown in FIG. 10, when the character string “VWX” is additionally input, the character string “VWX” is temporarily input.
After the "X" is dummy-displayed, as shown in FIG. 13, these character strings "UXWX" are displayed on the display 22 as outline modified characters.

On the other hand, in the tape print control, when the cursor movement key is operated (S15: Yes, S16.S1).
7: No), and when the dummy display flag DF is not set (S18: No, S19: Yes), the cursor pointer value CP is updated and set to a value according to the type of cursor movement key (S26), S13. ~ Return to S15 through S14. For example, as shown in FIG. 10, the print format information and the code data of the character string “UXWX” are stored in the text memory 61, and the cursor pointer value CP indicates the character “W” by operating the cursor movement key. While the cursor is on, the cursor K is displayed at the left end of the character "W" as shown in FIG.

Here, when the character "n" is inserted and input, the code data of the character "n" is displayed in the text memory 61 immediately before the code data of the character "W", as shown in FIG. Is entered. As a result, as shown in FIG. 15, the character "n" is controlled by the dummy display data creation processing control.
Is Mincho typeface and 3 at the input position indicated by the cursor K
The size of 2 dots is once displayed as a dummy, and the cursor K is displayed at the display position moved to the display lower side by the character width of the character "n". At this time, the character width of the character "W" is larger than the character width of the character "n".
The right half of is displayed. After that, as shown in FIG. 16, the character “n” is controlled by the print image display processing control.
Is displayed as a modified character of the outline at the display position, and the character string "WX" is moved to the lower display side and displayed.

By the way, in the text memory 61, FIG.
As shown in, when the print format information and the character code "U" are stored, the set tape length (15c
When m) is set and the even distribution flag WF is set, the character "U" is displayed on the display 22 as an outline modification character based on the print format information as shown in FIG. ,
The cursor K is displayed at the right end of the set tape length. When the character "V" is inserted and input,
As shown in FIG. 9, the character “V” is temporarily displayed in dummy at the input position indicated by the cursor K in Mincho typeface and in a size of 32 dots. After that, by the print image display processing control, as shown in FIG.
The character string "UV" is displayed by being evenly allocated in the set tape length, and is a modifier character of the outline and evenly allocated.

When "vertical writing" is set in the print format information and "gothic typeface" and "no modification" are set, the input character strings "WE" and "space" are entered. As shown in FIG. 21, a print image is displayed vertically in a Gothic typeface. Here, when the character string “ARE” is input, as shown in FIG. 22, the character string “ARE” is temporarily displayed at the input position indicated by the cursor K in the Mincho typeface and horizontally by dummy display. After that, by the print image display processing control, as shown in FIG. 23, the character string "ARE" is displayed.
Is displayed vertically in Gothic typeface.
That is, when the vertical writing is instructed, the dummy display is once made by the horizontal writing, so that the input character string can be easily confirmed.

Next, in the tape print control, when the print key is operated while the dummy display flag DF is not set (S15: Yes, S16 to S19: No, S
20: Yes), the print processing control is executed (S27), and the process returns to S13. Since this print processing control is similar to the normal print processing, a brief description will be given. The print format information and the character code are sequentially read from the text memory 61, and the character code of the character code is read based on the print character search table and the print character index table. The printing dot pattern data in the printing CGROM 54 is read out, expanded in the printing data buffer 67, and combined and stored, and the printing dot image data in the printing data buffer 67 is printed by the printing mechanism PM.
And is printed on the printing tape 19. by the way,
When a key other than the print format setting key, the print enable key, the cursor movement key, and the print key is operated (S15: Yes, S16 to S20: No), the process corresponding to the operated key is executed (S28). , Return to S13.

As described above, in the print format information, in addition to the data on the character size and typeface to be printed out and the type of character decoration, set tape length data for setting the print direction length of the print area is set. For the latest input character, the dummy display data is displayed in the specified Mincho typeface prior to the image display, even if it takes processing time to perform character modification on the input character display dot pattern data. After creating and displaying a dummy once, when various key operations such as printable keys and function keys are not performed, all document data including the latest input character is displayed as an image based on the print format information. Therefore, the display process for the dummy display of the input character in the specified Mincho typeface is simplified. Code data of the input character since it can be stored quickly in the text memory 61,
Although it is a dummy display, the display processing in the image display can be speeded up, and the key input processing can be speeded up as well.

Further, when various key operations such as the printable key and the function key are not performed, the display dot pattern data including the dummy display data stored in the display data buffer 66 is the display dot pattern data for the document data. Since the data is overwritten, when entering a character, the character can be quickly displayed as a dummy to speed up the display process, and the document waiting time can be effectively used to display an image of the document data. be able to. Further, since the dummy display data is created by using the display dot pattern data of the display character size corresponding to the print character size SZ of the print format information, the input character is displayed by the display character size at the input position, and a more image display is performed. It is possible to display a dummy close to. Further, when "vertical writing" is set, the input character string is temporarily displayed horizontally in a dummy display, so that the input character string can be easily confirmed.

In addition, even when the even allocation flag WF is set in the print format information and the even allocation process is executed on the data of the document including the input characters, dummy display data relating to the input characters is created and the dummy display data is created. By displaying, it is possible to speed up the display process of the input character, and also to speed up the key input process as well.

Here, the correspondence between each means described in the claims and the configuration in the above-mentioned embodiment will be explained. The one equivalent to the dummy display data creating means is particularly the dummy display data creating processing control. S30 to S32, which corresponds to the display data overwriting means, particularly S68 of the display image generation processing control, and those which correspond to the even allocation means, particularly S67 of the display image generation processing control.
Is.

The predetermined typeface used for the dummy display may be constructed so that the operator can arbitrarily select and set it from Mincho or Gothic typefaces. In addition, in the case of a beginner with a slow key input speed, an image is displayed immediately after a short dummy display for each character input, and when the display screen changes drastically, the display time for the dummy display is set to, for example, 1 It may be configured such that it can be set to seconds. 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 mechanism and capable of character modification processing.
