The AM 60 is also provided with a work memory 68.

Next, the tables TB1 to TB5 will be described. The table TB1 shown in FIG. 5 sets the relationship between the detection signal of the cassette sensor 42 and the tape width of the tape cassette CS mounted in the tape printer 1. The table TB2 shown in FIG.
The character size of the character font stored in
The range of the display font and the range of the print font are shown. The table TB3 shown in FIG. 7 is a table in which the correspondence relationship between the tape width, the number of dots of the printable width of the tape, the number of lines of characters or symbols printed, and the size of the printed character (point value: number of dots) is set in advance. When the tape width and the number of print lines are determined, the print character size is determined from this table.

A table TB4 shown in FIG. 8 has a print character size (point value) and three kinds of display magnifications (basic magnification,
(2 times, 3 times), the correspondence relationship with the display character size is set in advance. For example, the table TB3 determines the print character size from the tape width and the number of print lines, and based on this table TB4 and the display magnification R. In addition, the display character size is determined from the print character size. A table TB5 shown in FIG. 9 is a table in which the tape width, the display magnification R, the upper end cut area of the display 22, the image display area (effective display area), and the area width of the lower end cut area are preset. .

As shown in the remarks column of the table TB5, in the display 22, the image display area 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. It The upper end cut area and the lower end cut area are areas that are not utilized as an image display area by performing shadow display with diagonal lines. The width of the image display area,
Since the display character size is increased in accordance with the increase of the tape width and the display character size is increased in accordance with the increase of the tape width, it becomes possible to display the characters and symbols in 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 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 = 1, 2, 3, ...) Indicates each step. When the power is turned on by the power key on the keyboard 3, this control is started, and first, the memories 61 to 68 of the RAM 60 are cleared, and an initialization 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 tape width data 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, standard format information data (print line number, print character size, typeface, etc.) is stored in the first 2 bytes of the text memory 61 (S2). For example, the number of print lines is set to 1, and the print character size SZ is
The print character size calculated from the table TB3 is set based on the tape width and the print line number "1", and the Mincho typeface is set as the typeface. Next, as the document input screen on the display 22, a document input screen which is an image display area corresponding to the tape width calculated in S2, the print character size, and the table TB4 are set as the basic magnification. A cursor K having the size of the display character size (see FIG.
0 (see 0) is displayed (S4). In this document input screen, the 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 cut. The area and the shadow are shaded. In this case, the display dot image data is expanded in the display data buffer 64 and the data is displayed.

Next, a print image display process for displaying the characters and symbols stored in the text memory 61 on the display 22 as a print image is executed (S5). For convenience of explanation, the print image display process will be described. 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), the 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 executed based on these data. To be done.

First, when the tape width is 6 mm (S
60: Yes), the display magnification R is incremented by 1 (S61), and when the display magnification R is 4 next (S62: Yes)
), The display magnification R is set to 1 (S63). That is,
If the tape width is 6 mm, the display character size at the basic magnification is small, so there is a lot of room for enlarged display.
Display magnification R indicates basic magnification "1" → "2" → "3" →
The data 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 set to 1 (S67).

That is, when the tape width is 9 mm, since there is not much room for enlarged display, the display magnification R is switched to "1" → "2" → "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 to 1 (basic magnification) and the data of the display magnification R is stored in the display magnification memory 67. Stored (S6
9) Next, the display dot image data of the upper cut region and the lower cut region is changed according to the change of the display magnification and is expanded in the display data buffer 64 (S70).
After this 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 then the process proceeds to S5. In this format information setting process control, since the format setting screen on which the format setting contents such as the number of print lines, the print character size, and the typeface name can be collectively set is displayed on the display 22,
Operate the cursor movement keys to move the cursor to the setting item "Print font size name" or "Typeface name", enter the number key corresponding to the desired setting contents, and then press the Enter key to display the format information as text. The change format information is stored in the memory 61. The modified format information including the modified setting information is stored in the text memory 61 in 2 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 storage 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, and the print image display process is executed (S12). S5). Next, this print image display processing will be described with reference to FIGS.
This will be described with reference to 2. At this time, the text memory 6
14, the standard format information, the first modified format information, the characters "ABCD", the second modified format information, ...
・ Sequentially stored.

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 64 is obtained for each of the characters and symbols to be displayed, and the arrangement position information is the arrangement position. It is stored in the information memory 63 (S30). Note that the arrangement position information is, for example, the character arrangement position at the time of printing is obtained from the format information, the character code, the line feed code, and the dot pattern data for printing, and the coordinate value is multiplied by 1/3 to obtain the arrangement position for display. Be asked to do so.

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

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

Next, the data count value DC is incremented by 1 (S37), and then the search address and the end 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 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 generating process 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 described above.
And the display magnification R of the display magnification memory 66 in the table TB
4, the display character size is calculated (S50), and 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 determined. It 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 designated by the layout position data of the character stored in the layout position information memory 63. And (S5
4) Then, this control is ended, and the process returns to S37 of the print image display processing control.

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

Next, in the main routine, when the print key is operated (S13: Yes), the printing process on the tape is executed (S14), and the process returns to S5. Since this printing process is similar to the normal printing process, a brief description will be given. Format information and character codes are sequentially read from the text memory 61, and the dot pattern data in the CGROM 53 of the character code is read based on the search table and the index table. The read dot image data is read out, expanded in the print data buffer 65, and combined and stored. The print dot image data in the print data buffer 65 is output to the printing mechanism PM,
It is printed on the printing 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), the process corresponding to the operated key is executed (S15), and the process returns to S5. .

Here, in the text memory 61, as shown in FIG.
The display example on the display 22 in the state where the data “ABCD” among the document data shown in FIG. 15 is input is as shown in FIGS.
15 to 19, the tape width is 24 mm,
It is a case of 18 mm, 12 mm, 9 mm, and 6 mm. However, when all the 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 printing control described above will be described. In this control,
Basically, the print character size is set to be substantially proportional to the tape width, and the display character size is set to be substantially proportional to the print character size. In this way, since the display character size is set substantially in proportion to the tape width, it becomes easier to understand the printing state of the character in relation to the tape width, and the operability is improved.

In addition, the upper end and the lower end of the display 22 are shadow-displayed with the upper end cut region and the lower end cut region, respectively, and the image display region having a width substantially proportional to the tape width is displayed in the central portion in the width direction of the display 22. Is set to display the characters of characters and symbols in the image display area with the same image as the printed state, so that the printed state of the characters printed on the tape can be more accurately related to the tape width. Since the information can be grasped, the operability at the time of inputting the document data can be improved and the setting error of the print character size can be prevented.

Since the display magnification, that is, the display character size can be enlarged and set via the display size setting key, the character can be appropriately enlarged and displayed on the display 22 as necessary, so that the tape width is reduced. If it is small, it can be enlarged and displayed when inputting on a plurality of lines, and the operability is improved.

Here, the correspondence between each means described in the claims and the configuration in the above embodiment will be described. The data storage means corresponds to the text memory 61 of the RAM 60 and the font storage means. Corresponds to the CGROM 53, the display data buffer corresponds to the display data buffer 64 of the RAM 60, and the tape width detecting means corresponds to the cassette sensor 42 and the protruding piece 20 attached to the tape cassette CS. The table TB1 corresponding to the display data creating means is the control device C (in particular, the tables TB3 and TB4,
11 and 12). The size enlargement setting means corresponds to the display size setting key, the control device C (in particular, the display magnification memory 6 of the RAM 60).
7, the flowchart of FIG. 13 and the like).

In place of the cassette sensor 42,
It is also possible to apply a detection means for directly detecting the tape width with an optical sensor or the like in the middle of the tape transport path,
Alternatively, instead of shadow-displaying the upper cut region and the lower cut region of the display 22, these regions and the image display region may be divided by an appropriate boundary line, and instead of the CGROM 53. A display CGROM and a printing CGROM independent of the display CGROM may be provided, a tape of 24 mm or more may be applied as the tape, and the thermal head may be enlarged, and the display 22 may be the maximum tape.
