In a table TB5 shown in FIG. 9, the relationship between the tape width, the display magnification R, and the width of the upper cut area, the image display area (effective display area), and the lower cut area of the display 22 is set in advance. .

As shown in the remarks column of the table TB5, the image display area of the display 22 is an effective display area for displaying characters and symbols, and the width of the image display area is changed according to the tape width. You. The upper end cut area and the lower end cut area are areas that are not used as image display areas by performing shadow display with oblique lines. The width of the image display area,
Since the display character size is increased as the tape width is increased and the displayed character size is increased as the tape width is increased, characters and symbols can be displayed within the width of the image display area in a manner substantially similar to the printing state.

Next, the main routine of the tape printing control performed by the control device C of the tape printing apparatus 1 will be described with reference to the flowcharts of FIGS.
In the drawing, reference symbol Si (i = 1, 2, 3,...) Indicates each step. When the power is turned on by the power key on the keyboard 3, this control is started. First, each of the memories 61 to 68 of the RAM 60 is cleared, and an initial setting process for initializing the printing mechanism PM is executed (S1). next,
The cassette signal from the cassette sensor 42 is read,
The tape width is determined based on the cassette signal and the table TB1, and the data of the tape width is stored in the tape width memory 6.
6 and the width of the image display area is calculated based on the tape width and the table TB5 (S2).

Next, in the first two bytes of the text memory 61, data of standard format information (data such as the number of print lines, print character size, font, etc.) is stored (S2). For example, 1 is set for the number of print lines, and the print character size SZ is set to
The print character size calculated from the table TB3 based on the tape width and the number of print lines “1” is set, and the font is set to Mincho. Next, the basic magnification is determined on the display 22 based on the document input screen as an image display area corresponding to the tape width calculated in S2 as the document input screen and the print character size and the table TB4. A cursor K having a display character size (see FIG. 2)
0 is displayed (S4). In this document input screen, data of the upper cut area width, the image display area width, and the lower cut area width at the basic magnification corresponding to the tape width are read from the table TB5, and based on the data, the upper cut area and the lower cut area are read. The area and the area are shaded. In this case, the display dot image data is developed in the display data buffer 64, and the data is displayed.

Next, print image display processing for displaying characters and symbols stored in the text memory 61 on the display 22 as print images is executed (S5). This print image display processing is described for convenience of explanation. It will be described later. Next, it is determined whether or not there is a key input (S
6) If there is no key input, S6 is repeated, and if there is a key input (S6: Yes), the process proceeds to S7. When the display size setting key is operated to change the display magnification displayed on the display 22 (S7: Yes), a display size setting process is executed (S8). This display size setting process will be described with reference to FIG. Since the tape width data is stored in the tape width memory 66 and the current display magnification R data is stored in the display magnification memory 67, the determination of S60, S62, S64, and S66 is performed based on these data. Is done.

First, when the tape width is 6 mm (S
60: Yes), the display magnification R is incremented by 1 (S61). Next, when the display magnification R is 4 (S62: Yes).
), The display magnification R is set to 1 (S63). That is,
When the tape width is 6 mm, the display character size at the basic magnification is small, so there is a large room for enlarged display.
Display magnification R indicates basic magnification "1" → "2" → "3" →
The display is switched to "1", and the data of the display magnification R is stored in the display magnification memory 67 (S69). On the other hand, when the tape width is 9 mm (S60: No, S64: Yes),
The display magnification R is incremented by 1 (S65), and when the display magnification R is 3 (S66: Yes), the display magnification R is increased.
Is set to 1 (S67).

That is, when the tape width is 9 mm, since there is not much room for the enlarged display, the display magnification R is switched from "1" to "2" to "1" indicating the basic magnification. The data of the display magnification R is stored in the display magnification memory 67 (S69). When the tape width is 12 mm or more (S60: No, S64: No), since there is no room for enlarged display, the display magnification R is fixed at 1 (basic magnification), and the data of the display magnification R is stored in the display magnification memory 67. Stored (S6
9) Next, in accordance with the change of the display magnification, the display dot image data of the upper cut area and the lower cut area is changed and is developed in the display data buffer 64 (S70).
After the display size setting process, the process returns to S5.

In the main routine, when the format setting key is operated (S9: Yes), the format information setting process control is executed (S10), and thereafter, the process proceeds to S5. In this format information setting process control, a format setting screen on which the format setting contents such as the number of print lines, the print character size, and the font name can be collectively set is displayed on the display 22.
Operate the cursor movement key to move the cursor to the setting item "print character size name" or "font type name", enter the numeric key corresponding to the desired setting content, and then operate the execution key. It is stored in the memory 61 as change format information. The changed format information including the changed setting information is stored in the text memory 61 in two bytes following the standard format information, and then the process proceeds to S5 (FIG. 14).
reference).

Next, when a printable key, which is a key for alphabetic characters, numbers, symbols, etc., is operated (S1
1: Yes), the document data storing process of storing the code data of the operated printable key as the document data in the text memory 61 is executed (S12), and then the process proceeds to S5 to execute the print image display process (S12). S5). Next, the print image display process will be described with reference to FIGS.
This will be described with reference to FIG. At this time, the text memory 6
1, as shown in FIG. 14, standard format information, first changed format information, characters "ABCD", second changed format information,.
Are stored sequentially.

When this control is started, the data in the text memory 61 is first searched sequentially from the head address.
Based on the format information, the character code, and the line feed code, for each of the characters and symbols to be displayed, arrangement position information for expanding the display dot pattern data in the display data buffer 64 is obtained. The information is stored in the information memory 63 (S30). 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, multiplying the coordinate value by １ ／, and determining the arrangement position for display. Is required.

Next, an initialization process for initializing 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 of the text memory 61 is set as the start address pointer value SP (see FIG. 15), and the next address (end) of the current end address of the text memory 61 is set as the end address pointer value EP. Address + 2) is set (see FIG. 14), and an initial value “0” is set as data count value DC.

Next, since the format information data and the character code are each composed of 2 bytes, the data of the search address obtained by adding the doubled data count value DC to the start address is read (S32). Is the data of the format information (S33: Yes), the data of the format information is stored in the work memory 68 (S34), and then S37
Move to If the data read from the search address is printable character, symbol, or space data (S33: No, S35: Yes), display image generation processing is executed (S36), and then the process proceeds to S37. .

Next, the data count value DC is incremented by one (S37). Next, a search address obtained by adding an address obtained by doubling the data count value DC to the start address pointer value (start address) SP and the end address are added. When the address indicated by the address pointer value EP does not match and there is a character to be displayed in the text memory 61 (S38: No), S32 to S38 are repeatedly executed.

Next, the display image data generation processing executed in S36 will be described with reference to FIG.
When this control is started, the print character size SZ of the format information stored in the work memory 68 in S34 is described.
And the display magnification R of the display magnification memory 66 are stored in a table TB.
The display character size is calculated by applying to step S4 (S50). Based on the display character size and the search table, the index address of the CGROM 53 storing the dot pattern data of a group of characters and symbols of the character size is calculated. The character code is read (S51), and based on the index address, the index table, and the character code, the storage start address of the character code in the CGROM 53, that is, the font storage address is read (S52), and stored in the font storage address. The dot pattern data is read from the CGROM 53 and temporarily stored in the work memory 68 (S53).

Next, the dot pattern data stored in the work memory 68 is stored in the storage position of the display data buffer 64 indicated by the character position data stored in the position data memory 63. And (S5
4) After ending this control, the process returns to S37 of the print image display process control.

Next, in the print image display processing, S
After the execution of step 37, when the search address obtained by adding the doubled data count value DC to the start address matches the address indicated by the end address pointer value EP (S38: Yes), the display data buffer 64 The display dot image data expanded and stored is video R
It is output to the AM 24 and displayed on the display 22 (S
39), this control ends, and the process returns to S6 of the main routine.

Next, when the print key is operated in the main routine (S13: Yes), the printing process on the tape is executed (S14), and the process returns to S5. Since this printing process is the same as the normal printing process, the format information and the character code are sequentially read from the text memory 61, and the dot pattern data of the character code in the CGROM 53 is read based on the search table and the index table. The read dot image data is read out, expanded and stored in the print data buffer 65, and the print dot image data in the print data buffer 65 is output to the printing mechanism PM.
It is printed on the print tape 19. On the other hand, when a key other than the display size setting key, the format setting key, the printable key, and the print key is operated (S13: No), processing corresponding to the operated key is executed (S15), and the process returns to S5. .

Here, the text memory 61 shown in FIG.
The display example on the display 22 in a state where the data of “ABCD” is input among the document data shown in FIG. 15 is as shown in FIGS. 15 to 19 in the case of the basic display magnification.
15 to 19 show that the tape width is 24 mm,
18 mm, 12 mm, 9 mm, and 6 mm. However, in a state where all data of “ABCD”, “EFG”, and “HIJK” are input, as shown in FIG.
“EFG” and “HIJK” are displayed in two lines. still,
The cursor K is also shown.

The operation of the display control included in the tape print control described above will be described. In this control,
Basically, the print character size is set to be approximately proportional to the tape width, and the display character size is set to be approximately proportional to the print character size. As described above, since the display character size is set to be approximately proportional to the tape width, the printing state of the character can be easily grasped in relation to the tape width, and the operability is improved.

Further, an upper cut area and a lower cut area are shadow-displayed at an upper end and a lower end of the display 22, respectively, and an image display area having a width substantially proportional to the tape width is displayed at the center in the width direction of the display 22. Is set to display characters and symbol characters in the image display area in the same image as the print state, so that the print state of the characters printed on the tape can be more accurately related to the tape width. Since it is possible to grasp, it is possible to improve the operability at the time of inputting the document data, and to prevent setting error of the print character size and the like.

Since the display magnification, that is, the display character size can be enlarged and set via the display size setting key, the characters can be appropriately enlarged and displayed on the display 22 if necessary. If it is small, it can be displayed in an enlarged manner, for example, when input is made on a plurality of lines, and operability is improved.

Here, the correspondence between the means described in the claims and the configuration in the above embodiment will be described. The data storage means is equivalent to the text memory 61 of the RAM 60, and the font storage means. Is equivalent to the CGROM 53, the equivalent to the display data buffer is the display data buffer 64 of the RAM 60, and the equivalent to the tape width detecting means is the cassette sensor 42 and the projecting piece 20 attached to the tape cassette CS. The table TB1, which corresponds to the display data creation means, includes the control device C (in particular, the tables TB3 and TB4,
FIG. 11 is a flowchart of FIG. 11 and FIG. The display size setting key is equivalent to the display size setting key and the control device C (in particular, the display magnification memory 6 of the RAM 60).
