2. Description of the Related Art Conventionally, the applicant of the present invention has disclosed in Japanese Patent Laid-Open No. 5-177
As described in Japanese Patent Publication No. 898, a keyboard, a display, and a printing mechanism are provided, and a tape (for example, 12
mm and 18 mm tape width) can print letters and symbols,
In addition to these characters and symbols, we have proposed a tape printer that can print mixed barcodes. This tape printing device is suitable for printing a label such as a title of a file and creating a tape to be attached to a file or various storage cases.

By the way, the inventors of the present application display a document input from a keyboard on a display in a character arrangement state, that is, a print image, printed on a printing tape based on preset print format information (format information). I was inspired to do it. That is, the display dot pattern data for a plurality of display character sizes corresponding to a plurality of print character sizes is stored in the font ROM provided in the control device, while the document data input from the keyboard is set to the print character size. Displayed as a print image on the display with dot pattern data for display of the corresponding display character size, and the input barcode data is converted to barcode standard module data (white bar or black bar data). , The white bar and the black bar are displayed with the height according to the display character size.

Here, the movement of the cursor indicating the input position or the editing position of the document is based on the cursor right movement command or the cursor left movement command by the cursor left / right movement key operation, similarly to the movement control of a normal word processor. In addition, it is configured to move and display each character that is adjacent to the moving direction in the current display line. By the way, in a printed image of a bar code including laterally enlarged symbols and numbers or symbols in multiple lines, there is a long pattern in which the display pattern of one unit is longer than the length of the display in the display line direction. Therefore, when the cursor left movement key or the cursor right movement key is operated while a document including a long pattern that cannot be entirely displayed on one screen is displayed on the display as a print image, the cursor is For each display pattern of the unit, the screen is scrolled so that the cursor can be displayed at the position where the cursor moves from the beginning position to the ending position or vice versa. ing.

[0005]

As described above, in a tape printer capable of displaying an input document as a print image, for a long pattern which cannot be displayed on one screen, the cursor can be moved when the cursor left / right key is operated. Moves from the start position to the end position of the long pattern or from the end position to the start position all at once and the screen is scrolled, and the cursor is displayed together with the start part or the end part of the long pattern. There is a problem that the central part of the pattern is not displayed, and the central part cannot be confirmed on the display.

It is an object of the present invention to provide a document processing apparatus capable of displaying the entire long pattern by divisional display even if the long pattern cannot be entirely displayed on one screen of the display.

For this reason, the flag data of the head side flag TF set when the display position of the cursor K at the start of screen scrolling of a long pattern that cannot be displayed entirely on one screen is stored. It

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. In the figure, reference numeral Si (i = 10, 11, 12, ...) Indicates each step.

Here, as shown in FIG. 6, the display 22 has a predetermined number of dots (eg, 16 dots) at its left end.
Left movement prohibited area (left margin zone)
LM) is set, a right movement prohibited area (write margin zone RM) of a predetermined number of dots (for example, 16 dots) is set at the right end, and further inside these both movement prohibited areas. A movement allowance area is set, and the cursor K is movable within this movement allowance area. Therefore, the left margin pointer value LMP is a predetermined value corresponding to the end of the left movement prohibited area LM in the display buffer 67, and the right margin pointer value RMP.
Is a predetermined value corresponding to the start end of the right movement prohibited area RM. However, in each of the drawings after FIG. 21, it is assumed that the display data of the display buffer 67 is displayed on the display 22.

When the power is turned on by the power key on the keyboard 3, this control is started, and first, the memories 61 to 70 of the RAM 60 are cleared, and particularly the parameter memory 62.
Initial setting processing for initializing the printing mechanism PM, while initial value "0" is set in each of the cursor absolute position pointer value KPA, the cursor display position pointer value DKP, the display start position pointer value TDP and the cursor pointer value KP. 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. A rod-shaped cursor K having the size of the displayed character is displayed (S11). For example, as shown in FIG. 18, in the first 2 bytes of the text memory 61, "no modification" is used as the character decoration, "Mincho typeface" is used as the font number, and "44pt (points)" is used as the print character size. Standard format information including is stored.

Next, in order to display the character stored in the text memory 61 as a print image, a print image creating process is executed (S12), and a print image displaying process is further executed (S13). This print image display processing will be described later for convenience of description.

When the format setting key is operated (S14.S15: Yes), the format information setting process control is executed (S20), and the process proceeds to S14 via S12 and 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, when the cursor K is moved to the setting item "character modification type name", "print character size name" or "typeface name", the number key corresponding to the desired setting content is input, and the execute key is operated. Format information including the data of the character modification number and the print character size set by numbers is stored in the text memory 61 as the modified format information.

Next, when a printable key such as an alphabetic character key, a symbol key, or a numeric key is operated (S14: Yes, S15: No, S16: 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 (S21). Since each character has 2 bytes, the cursor pointer KP is incremented by 2 bytes (S2).
2) Go to S14 via S12 and S13. For example, when the character string "ABC" is input, the character codes A, B and C are sequentially stored as shown in FIG.

Next, when the bar code key is operated to input the bar code data (S14: Yes, S
15.S16: No, S17: Yes), the bar code data input process control is executed (S23), the cursor pointer KP is incremented by 2 bytes (S22), and the process proceeds to S14 via S12 and S13. In this bar code data input process control, for example, the standard "CODE-39" is selected by a bar code standard setting process control (not shown), and the numeric string "12345678901" is selected as the bar code data.
234567 ”, the bar code buffer 63, as shown in FIG. 19, includes bar code parameter data BCPD including standard name data, check digit data, and effective digit number data, and check digit presence / absence information data. CDI, start code, start code and start code SAC (*), number string, stop code SOC
(*), The end code and the end code are stored, and in the text memory 61, as shown in FIG. 18, a bar code instruction code BCZ for instructing the input of the bar code data is stored.

Next, the print image creation processing control of S12 (see FIG. 8) will be described. Here, it is assumed that the text memory 61 stores a character string "ABC" and barcode data as document data, as shown in FIG. At this time, as shown in FIG. 20, the print dot pattern data relating to the character string "ABC" and the barcode data is sequentially expanded in the print data buffer 69, and the display dot pattern data relating to the character string and the barcode is displayed. Is the display data buffer 6
6 will be developed in sequence. Here, the print end position PEG _A is the expansion end position of the printing dot pattern data of the character “A”, the print end position PEG _B is the expansion end position of the printing dot pattern data of the character “B”, ... PEG _Z
Is the expansion end position of the dot pattern data for printing the barcode, and the display cursor position DKG _A is the character "A".
Display cursor position and display cursor position DKG corresponding to the expansion end position of the display dot pattern data for display _B is the display cursor position corresponding to the expansion end position of the display dot pattern data for the character "B", ... Display cursor position DKG
_Z is the display cursor position corresponding to the expansion end position of the dot pattern data for displaying the barcode. The print end position PEG ₀ is the start address of the print data buffer 69, and the display cursor position DKG ₀ is the start address of the display data buffer 66.

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 66 is obtained for each character to be displayed, and the arrangement position information is the display character position.
It is stored in the arrangement position information memory 65 as DMG (S3
0). That is, the display character position information is obtained by, for example, sequentially adding the character widths in each print line from the format information, the character code, the line feed code, and the dot pattern data for printing to obtain the print character position at the time of printing for each character. In the present embodiment, since the ratio of the character width of the print character and the display character is 3: 1, the coordinate value of the print character position is 1/3.
The display character position is calculated by multiplying.

Next, an initialization process for initializing the parameter information relating to the printing process in the parameter memory 62 is executed (S31). That is, in the parameter memory 62, the start address pointer value SP is set to the start address of the text memory 61 (see FIG. 18), and the end address pointer value EP is set to the address next to the end address of the text memory 61 (see FIG. 18). 18),
An initial value "0" is set as the data count value DC, "44pt" is set as the print character size SZ, and an initial value "0" is set as the print end position PEG.

Next, when the initial flag 1F is reset, that is, when one unit of display data designated by the cursor K is contained within one screen (S32: Yes), the format information data and the character code are set. Each have a 2-byte structure, and when the search address obtained by adding the address obtained by doubling the data count value DC to the start address and the cursor pointer value KP do not match (S33: No), the process proceeds to S35. When the address matches the cursor pointer value KP (S33: Yes), the value of the display cursor position DKG which is 1/3 times the print end position PEG is set in the cursor absolute position pointer value KPA (S34). .
When the first flag 1F is set, that is, when the cursor K is moved by operating the cursor movement key and one unit of display data indicated by the cursor K does not fit within one screen, the actual cursor display position Since the cursor pointer value KP does not match (S32: No), S
Steps 33 to S34 are skipped and the process proceeds to S35.

Next, when the data at the search address is read (S35) and the data is format information data (S36: Yes), the print character size of the format information is changed and stored in the parameter memory 62. Format information change processing control is executed (S38). Next, the data count value DC is incremented by 1 (S40), and the start address pointer value (start address) SP is added with the search address obtained by adding the address obtained by doubling the data count value DC and the end address pointer value EP. The address to be displayed does not match and the data to be displayed is still in the text memory 61.
If it exists in (1) (S41: No), S32 and subsequent steps are repeatedly executed.

Then, when the search address data is printable code data such as a character or a bar code (S36: No, S37: Yes), display image generation processing control (see FIG. 9) is executed (see FIG. 9). S39).

When this control is started, first, the display character size corresponding to the print character size in the parameter memory 62 is read based on the character size conversion table TB1 (S50), and the printable code data is the barcode. If not character data BCZ, but character or symbol code data (S51: No), a series of character and symbol dot pattern data of that display character size is stored based on this display character size and display character search table. C for display
The index address of GROM 53 is read (S5
2) Further, based on the index address, the display character index table and the code data, the storage start address of the code data in the display CGROM 53, that is, the font storage address is read (S53) and stored in the font storage address. The display dot pattern data is read from the display CGROM 53,
In the display data buffer 66, it is stored in the display character position corresponding to the print character position (S54). However, when the printable code data is the bar code designation data BCZ (S51: Yes), the bar code module data is created based on the bar code standard (S56), and S54 to S54.
55 is executed.

Next, a value obtained by adding the character width P of the character such as the character or the symbol is stored in the print end position PEG (S55), and this control is ended, and S40 of the print image creation processing control is performed. Return to.

Next, in the print image creation processing control, after executing S40, the search address obtained by adding the address obtained by doubling the data count value DC to the start address SP and the address designated by the end address pointer value EP are obtained. When they match (S41: Yes), this control is terminated and the process returns to S13 of tape printing control.

Next, the print image display processing control of S13 (see FIG. 10) will be described.

First, the case where no character code is stored in the text memory 61 will be described. Cursor absolute position pointer value KPA, display start position pointer value TDP, cursor pointer value KP, cursor display position pointer value DKP and printing. End position All PEGs are "0"
Therefore, all of S60 to S61 are determined to be No and S62 is determined to be Yes, and the left scroll processing control (see FIG. 12) is executed (S65).

When this control is started, the cursor absolute position pointer value KPA is equal to the write margin pointer value RMP.
Since this is smaller than (S75: Yes), "0" is set to the display start position pointer value TDP, and the cursor absolute position pointer value KPA (= 0) is set to the cursor display position pointer value DKP (S77). ), Terminates this control, and returns to S67 of the print image display processing control,
The display dot image data for one screen is read from the address designated by the display start position pointer value TDP in the display data buffer 66, and the display buffer 67
Is output to (S67). As a result, no data is displayed in the display buffer 67 on the display 22 via the video RAM 24. next,
The image data of the cursor K is output to the address designated by the cursor display position pointer value DKP of the display buffer 67 (S68), this control is ended, and the process returns to S14 of tape printing control. As a result, as shown in FIG. 21, the image data of the cursor K indicated by the chain double-dashed line is output at the start position of the display buffer 67, and the cursor K is displayed at the left end of the display 22.

Next, when the character "A" is input,
Since the cursor pointer value KP is incremented (S21) (indicated by KP1 in FIG. 18), the print end position PEG
Is added by the character width P of that character (S55), and the cursor absolute position pointer value KPA is changed accordingly (S55).
34). As a result, in the print image display processing control,
As shown in FIG. 21, the cursor absolute position pointer value KPA
The display start position pointer value TDP is smaller than that (S60: N
o), the difference between these pointer values KPA and TDP is smaller than the right margin pointer value RMP (S61: No), and the difference between these pointer values KPA and TDP is larger than the left margin pointer value LMP (S62: No), the cursor movement processing control in the display screen (see FIG. 13) is executed (S6

When this control is started, the write margin pointer value RM is calculated from the cursor absolute position pointer value KPA.
Since P is large (S80: Yes), "0" is set to the display start position pointer value TDP and the cursor absolute position pointer value KPA is set to the cursor display position pointer value DKP (S82), and this control ends. Then, S67 to S68 of the print image display processing control are executed. The cursor absolute position pointer value KPA is the write margin pointer value RMP.
In the above case (S80: No), the cursor display position pointer value DKP is set to a value obtained by subtracting the display start position pointer value TDP from the cursor absolute position pointer value KPA (S81), and this control is ended. As a result, as shown in FIG. 21, the character "A" is displayed on the left end of the display 22 and the cursor K is displayed at the position designated by the cursor display position pointer value DKP.

By the way, as shown in FIG. 22, when the input character string "AB" is displayed on the display 22 and the cursor K is displayed on the right side of the character "B", the character "C" is displayed. Is newly input, the cursor pointer value KP is similarly incremented (indicated by KP2 in FIG. 18).
Is added with the character width P of the character (see PEG _C
), And the corresponding cursor absolute position pointer value KP
A is changed. As a result, in the print image display processing control, as shown in FIG. 22, the display start position pointer value TDP is smaller than the cursor absolute position pointer value KPA (S60: No), but the difference between these pointer values KPA and TDP is Since it is larger than the write margin pointer value RMP (S61:
Yes), right scroll processing control (see FIG. 11) is executed (S64).

When this control is started, the display start position pointer value TDP is a value obtained by subtracting the right scroll predetermined position (corresponding to the cursor return position, for example, the right end of the movement allowable area) RSP from the cursor absolute position pointer value KPA. Is set, and the cursor display position pointer value DKP is set to a value obtained by subtracting the display start position pointer value TDP from the cursor absolute position pointer value KPA (S70), and this control is ended to control the print image display processing. S67 to S68 are executed.
