Then, a tape printing apparatus suitable for producing a tape-shaped label suitable for attaching to a spine of a file was put into practical use, and a tape printing apparatus provided with various editing functions was proposed. In this tape printer, the width of the tape can be changed by exchanging the tape cassette.

[0003] The inventors of the present invention use a keyboard to convert a document input from a keyboard into a print image similar to a print output based on print format information (format setting information), in particular, print character size and font. I thought of displaying on a small display. That is, for a large number of characters, a font storage memory for storing dot pattern data of a display font over a plurality of character sizes and a plurality of typefaces is provided.
While reading out the display dot pattern data corresponding to the print character size and typeface of the print format information from the font storage memory, the display dot image data of the document is created based on the number of lines and the display character size and displayed on the display. It is configured as follows. Here, when displaying data of a document composed of a plurality of lines, the display position of each display line after the second display line is set at a position where a space between the display line and the previous line is provided. Is set.

[0004]

As described above, in a tape printing apparatus having an image display function, print format information including a print character size and a typeface is set, and data of a document including a plurality of lines is converted to the print format information. When displaying an image based on print format information, the display is small, so the display area height of the display area of the display is relatively small, so the total required display is obtained by adding the display character size of each line of the document for the total number of lines. When the height becomes slightly larger than the height of the display area, a display error occurs.
As the character size is set to be smaller by a step, the display character size of the image display becomes smaller, and there is a problem that the display characters are difficult to read.

The arrangement position information memory 62 stores display position information in the display data buffer 64 of each character or symbol to be displayed.
The overlapping amount memory 63 stores the number of overlapping dots when a plurality of rows of display dot pattern data are overlaid and developed. The display data buffer 64 stores the inputted dot pattern data for displaying a plurality of characters and symbols, and the print data buffer 65 stores the dot pattern data for printing a plurality of characters and symbols to be printed. Are combined and stored as print dot image data. The flag memory 66 is set (flag data =
1) The flag data of the overlap development flag KF to be performed is stored.

Next, the routine of the tape printing control performed by the controller C of the tape printing apparatus 1 will be described with reference to the flowcharts of FIGS. Incidentally, the reference symbol S
i (i = 10, 11, 12,...) is each step.

When the power is turned on by operating the power key on the keyboard 3, this control is started.
Of the memories 61 to 66, and an initialization process for initializing the printing mechanism PM is executed (S10).
Next, print image display processing for displaying characters such as characters and symbols stored in the text memory 61 as print images is executed (S11). This print image display processing will be described later for convenience of explanation.

When the format setting key is operated (S12 / S13: Yes), format information setting processing control is executed (S16), and the process proceeds to S12 via S11. In the control of the format information setting process, a format setting screen on which the format setting contents such as the type name of the character modification, the print character size and the font name can be set collectively is displayed on the display 22, so that the cursor movement keys are operated. Then set the desired setting items "character decoration type name", "print character size name" and "font type name".
When the cursor is moved to ... and the enter key is operated after inputting the numeric key corresponding to the desired setting content, the format information including the character modification number set by the number and the data of the print character size SZ is stored in the text memory. 61 is stored in two bytes.

Next, when a printable key such as an alphabetical character key, a symbol key, or a numeric key is operated (S12: Yes, S13: No, S14: Yes), the code data of the operated printable key is two. A document data storage process for storing the data in the text memory 61 in bytes is executed (S1).
7), the print image display processing control is executed (S1)
1).

Next, the print image display processing control will be described with reference to FIG. At this time, as shown in FIG. 9, the text memory 61 stores "0 (no modification)" as the character modification number MD, "Mincho font" as the font name, and "6pt (point)" as the print character size SZ.・ Format information in which is set and the character string “ABCD” for 5 lines,
It is assumed that "EFG", "HIJ", "KLM", and "NOP" are sequentially stored.

When this control is started, first, an overlap amount calculation processing control (see FIG. 7) for calculating an overlap amount when a plurality of display lines of the document data are overlapped and displayed in the height direction is executed. (S30).

When this control is started, first, the display character size DZ corresponding to the print character size SZ set in the format information stored in the text memory 61 is read based on the character size conversion table TB1. (S4
0), the data in the text memory 61 is sequentially searched from the head address, and the number N of lines of the document data is obtained based on the format information, the character code and the line feed code (S41). Next, the display character size DZ of the document is calculated according to the illustrated arithmetic expression.
Are added for all rows to obtain a total required display height BH (S42).

Next, when the total required display height BH is larger than the display area height DH of the display area of the display 22, that is, when a document composed of a plurality of lines is in the height direction, the display area height of the display 22 is changed. If it does not fall within DH (S43: Yes), the overlapping development flag KF is set (S44), and the number of overlapping dots WD of the mutually adjacent display rows in the height direction is obtained by the illustrated arithmetic expression, and the overlapping is calculated. It is stored in the quantity memory 63 (S46), this control ends, and the process returns to S31 of the print image display processing control. For example, as shown in FIG.
Required display height BH of the document consisting of 5 lines stored in
Is 35 dots (7 dot size × 5), which is larger than the display area height DH (32 dots), and “1” dot is obtained as the number of overlapping dots WD.

On the other hand, when the total required display height BH is equal to or less than the display area height DH, that is, when a document including a plurality of lines can be displayed on the display area of the display 22 (S43: N
o), the overlap development flag KF is reset (S45), this control is terminated, and the process returns to S31.

Next, in the print image display processing control, the data in the text memory 61 is sequentially searched from the head address, and the characters and symbols to be displayed are determined based on the format information, the character code, the line feed code and the number of overlapping dots WD. With respect to each of them, arrangement position information for developing the display dot pattern data in the display data buffer 64 is obtained, and the arrangement position information is stored in the arrangement position information memory 62 (S31). The arrangement position information is obtained, for example, by calculating the character arrangement position at the time of printing from the format information, the character code, the line feed code and the printing dot pattern data.
It is obtained by multiplying by two times to obtain an arrangement position for display.

Next, when the overlap development flag KF is set and the document including a plurality of lines does not fit within the display area height DH (S32: Yes), the overlap display data creation processing control (see FIG. 8) is performed. It is executed (S33).

When this control is started, first, of the character strings on the first line in the document data stored in the text memory 61, the arrangement position information, format information, and display dot pattern in the arrangement position information memory 62 are displayed. Based on the data, display dot image data is created, developed from a predetermined origin position for the first display row of the display data buffer 64, and stored (S50). For example, as shown in FIG.
For the character string “ABCD” on the first line, display dot image data composed of display dot pattern data of each character is created and expanded in the display data buffer 64. Here, reference numeral 1GH indicates a display line height (7 dots) in the first display line.

Next, with respect to the character string of each line from the second line onward of the document data, the display dot image data is similarly created by overlapping the previous display line by the number of overlapping dots WD, and the display data buffer is created. The data is developed and stored at the respective development positions in S64 (S51), and this control ends, and the process returns to S35 of the print image display processing control. For example,
As shown in FIG. 10, for the character string "EFG" on the second line, display dot image data is created by combining display dot pattern data for each character, and the display dot image data on the second line is displayed. Are superimposed on the first display row by “1” dots, which is the number of superimposed dots WD, and are developed in the display data buffer 64. Here, reference numeral 2GH indicates a display line height (7 dots) in the second display line.

Similarly, the character string "HI" on the third line
The display dot image data for “J” is created, and is superimposed on the second display row by the number of “1” dots, and is expanded in the display data buffer 64. Here, the code 3GH is the third
Indicates the display line height in the display line. With respect to the character string “KLM” on the fourth line and the character string “NOP” on the fifth line, display dot image data is created, and the “1” dot number is displayed on the third display line and the fourth display line, respectively. The data are respectively developed in the display data buffer 64 in an overlapping manner. Where 4GH
Indicates the display line height in the fourth display line, and the symbol 5GH
Indicates the display row height in the fifth display row.

That is, as shown in FIG. 11, the total required display height BH (35 dots) of a document consisting of five lines obtained by adding the first display line height to the fifth display line height (1GH to 5GH) is calculated. As shown in FIG. 10, even when the display area height DH (32 dots) does not fit within the display area height DH, the display position in the height direction of each display row after the second display row is set to “1” dots of the number of overlap dots WD. Since the total required display height BH can be reduced to 31 dots by setting them individually, the display character size of the document consisting of the five lines is reduced to the display area height DH (32 dots). Display on the display 22 without the need to perform the operation.

In the print image display processing control, when the overlap development flag KF is not set and the document including a plurality of lines fits within the display area height DH (S32: No), the normal display data creation processing control is performed. Is executed (S34), and the routine goes to S35. The control of the normal display data creation processing will be briefly described. Based on the arrangement position information, the format information, and the display dot pattern data in the arrangement position information memory 62, the document data stored in the text memory 61 is used for each character. The display dot pattern data is synthesized by combining the display dot pattern data, and the display dot image data of a plurality of rows is generated. The predetermined development positions of the display data buffer 64 are sequentially arranged from the first display row without overlapping the display dot image data of each display row. Expanded from and stored.

Next, in the print image display processing control, the display dot image data developed and stored in the display data buffer 64 is output to the video RAM 24 and displayed on the display 22 (S35), and this control is terminated. Then, the process returns to S12 of the tape print control.

Next, in the tape print control, when the print key is operated (S12: Yes, S13 to S14: No,
S15: Yes), print processing control is executed (S18), and S11
And returns to S12.

Since the printing process control is the same as that of the normal printing process, the format information and the character code will be sequentially read out from the text memory 61, and based on the print character search table and the print character index table, the character information will be described. The dot pattern data for printing in the CGROM 54 for printing the code is read out and the print data buffer 65 is read out.
The print data buffer 65
Is output to the printing mechanism PM and printed on the printing tape 19.

By the way, when keys other than the format setting key, printable key and print key are operated (S13: Ye
s, S14 to S16: No), the process corresponding to the operated key is executed (S20), and the process returns to S12.

As described above, the total required display height B in the image display of the input multi-line document is described.
When H does not fall within the display area height DH of the display 22, the number of overlapping dots WD at which the total required display height BH becomes the display area height DH is calculated without setting the display character size DZ small. The document is displayed as an image by superimposing the display lines by the number of overlapping dots WD.
Especially for European characters, only the blank spaces provided above and below the characters themselves are deleted, so the document is printed in the largest possible display character size DZ without impairing the appearance of the image display of a multi-line document. Images can be displayed.

Here, the correspondence between the means described in the claims and the configuration in the above embodiment will be described. The equivalent of the print character size setting means is the format setting provided on the keyboard 3. The key and format information setting process control is equivalent to the height determining means, especially S40 to S43 of the overlap amount calculation processing control, and the equivalent to the overlap amount calculation means is particularly the overlap amount calculation process control. S46, which corresponds to the superimposed display data creation means is the superimposed display data creation processing control.

When the number of overlap dots WD obtained by the overlap amount calculation processing control is larger than a predetermined ratio of the display character size DZ, the data of the document is not overlapped so that the display lines are not overlapped so as not to deteriorate the appearance of the display characters. May be divided and displayed in the height direction. The print character size may be obtained by calculation from the tape width of the print tape 19 based on the cassette signal from the cassette sensor 42 and the number of lines of the input document. It should be noted that 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 within the scope of the technical idea of the present invention. Of course, the present invention can be applied to various tape printers having a keyboard, a display capable of displaying a print image, and a print mechanism, and capable of displaying an input document as a print image.
