Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a document processing apparatus capable of displaying an input document as a print image on a display, and more particularly to an apparatus for improving the horizontal scrolling of a document displayed as a print image. .

[0002]

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.

[0007]

As shown in the functional block diagram of FIG. 1, a document processing apparatus according to claim 1 inputs characters such as characters and symbols, patterns such as bar codes, and various commands. Input means for specifying and specifying, and a data storage means for storing input data such as characters and symbols,
Display means including a display capable of displaying a cursor and capable of displaying characters and symbols, display data creating means for receiving display data of the data storage means and creating display data of characters and patterns, and display data for storing display data The buffer, the head position memory for storing the display start position of the display data for one screen in the display data buffer, and the display means for receiving and displaying the display data for one screen from the display start position from the display data buffer And a cursor position memory for storing the current position of the cursor in the display data buffer in response to a cursor movement command to the left or the right, in the display data of the display data buffer. Based on this, it is too long in the direction of the display line so that the whole screen cannot be displayed on one screen. A pattern discriminating means for discriminating whether or not the display data of the turn is stored as one unit of display data, and the long pattern discriminated by the pattern discriminating means is divided into a plurality of lengths equal to or less than one screen length. Based on the division position determining means for calculating and storing one or a plurality of division positions in the display data buffer, the current position of the cursor stored in the cursor position memory, and the display start position stored in the start position memory, Cursor determining means for determining whether or not the cursor is within a predetermined movement permitting area on the display; and when the cursor determining means moves the cursor out of the movement permitting area when inputting a cursor movement command to the left or right. When it is determined and the long pattern is displayed on the display, the division position determined by the cursor and the division position determining means is displayed. A head position deciding means for deciding a display head position and outputting it to a head position memory is provided so as to be positioned at a predetermined cursor return position set in at least the right half portion of the movement allowable area on play. .

[0008]

In the document processing apparatus according to the first aspect, the input data such as characters and symbols are stored in the data storing means, and the display data creating means receives the input data from the data storing means and the characters and patterns are received. Display data is created and the display data is stored in the display data buffer. Further, the cursor position memory stores the current position of the cursor in the display data buffer in response to a cursor movement command to the left or right when inputting character data or operating the cursor movement key. By the way, the pattern discriminating means determines, based on the display data in the display data buffer, that the display data of a long pattern that cannot be entirely displayed on one screen is 1 because it is too long in the display row direction of the display.
In the display data buffer, the division position determining means divides the long pattern determined by the pattern determining means into a plurality of lengths equal to or less than one screen length, since the division position determining means determines whether or not the data is stored as a unit of display data. One or a plurality of division positions are calculated and stored.

On the other hand, the cursor determining means determines the cursor on the display based on the current position of the cursor stored in the cursor position memory and the display start position of one screen in the display data buffer stored in the start position memory. Since it is determined whether or not it is within the predetermined movement allowable area of
When the cursor movement command is input to the left or right and the cursor determination means determines that the cursor is out of the movement allowable area and the long pattern is displayed on the display, the head position determination means determines the cursor and the division position. The display start position after scrolling right or left is determined so that the division position determined by the determining means is located at a predetermined cursor return position set in at least the right half portion of the movement allowable area on the display. Output to memory. As a result, the display control means receives the display data for one screen from the display start position from the display data buffer and controls the display on the display of the display means.
The cursor is displayed and controlled at the predetermined cursor return position.

As described above, for a long pattern longer than one screen, one or a plurality of division positions having a length equal to or less than one screen length are calculated, and a cursor movement command to the left or right is input. As a result, when the cursor deviates from the predetermined movement-allowed area on the display, the cursor and its divided position are located at the predetermined cursor return position set in at least the right half of the movement-allowed area on the display. The display start position of the right scroll or the left scroll is determined, the display data for one screen is displayed from this display start position, and the cursor is displayed at the cursor return position of the movement allowable area.
By the divided display, the entire long pattern can be displayed.

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, on the display 22, as shown in FIG. 6, a left movement prohibited area (left margin zone LM) of a predetermined number of dots (for example, 16 dots) is set at the left end and the right end thereof is set. A right movement prohibited area (write margin zone RM) of a predetermined number of dots (for example, 16 dots) is set in the area, and a movement permitted area is set inside both of these movement prohibited areas. It is possible to move within this movement allowable 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 edge of the right movement prohibited area RM. It is a value. 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 the memories 61 to 70 of the RAM 60 are cleared first, and the parameter memory 62 in particular is cleared.
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. And
When the format key is operated (S14 / S15: Yes
), Format information setting processing control is executed (S20), S12
・ Go to S14 via 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 head 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 data of the search address is printable code data such as characters and bar codes (S36: No, S37: Yes), the display image generation processing control (see FIG. 9) is executed (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 the print image creation processing control of S40 is ended. Return to. Next, in the print image creation processing control, after executing S40, the start address SP
When the search address obtained by adding the address obtained by doubling the data count value DC and the address designated by the end address pointer value EP match (S41: Yes), this control is ended and S13 of the tape printing control is performed. Return to.

Next, the print image display processing control of S13 (see FIG. 10) will be described. First, a case where no character code is stored in the text memory 61 will be described. The cursor absolute position pointer value KP
