Since size names such as “S”, “M”,... Are displayed, a desired size name is designated and designated by the cursor K.
As a result, the size data is stored in the text memory 41, and the size mark SM indicating the size setting is set.
“▽” is displayed on the document input screen. For example, as shown in FIG. 11, first, an uppercase alphabet "A" input after a size mark SM "$" indicating the setting of the size "LL" is displayed on the document input screen.

Next, when the alignment position setting key is operated (S11: Yes, S12 / S15: No, S1
7: Yes), the alignment position setting process control (see FIG. 7) is executed (S18). When this control is started, first, the display of the document input screen is stopped, and the alignment position setting screen is displayed on the display 22 (S25). For example, as shown in FIG. 12, an alignment position setting screen is displayed on the display 22. In this setting screen, the selection number "1" is "base line", the selection number "2" is "top", and the selection number "3". "Is set to" lower end ". Then, when the numeric key "1" is operated (S26 / S27: Y
es), the base line flag KF is set and the upper end flag T
F and the lower end flag BF are respectively reset (S28),
This control ends, and the process returns to S11 of the tape print control.

And the lower end flag BF are respectively reset (S30), and when the numeric key "3" is operated (S26: Ye
s, S27 / S29: No, S31: Yes), the lower end flag BF is set, and the base line flag KF and the upper end flag TF are respectively reset (S32), and similarly, the process returns to S11. However, when a key other than the numeric keys "1" to "3" is operated (S26: Yes, S27.S
29. S31: No), the buzzer 20 for warning is sounded (S33), and the process returns to S26.

Next, when an external character key is operated during document creation (S11: Yes, S12 / S15 / S17:
No, S19: Yes), the external character registration mode is set, and the external character pattern creation / registration process control (see FIG. 8) is executed (S20). When this control is started, first, the registration data memory 42 is searched. If there is no registration dot pattern data, the start address α of the default size item is set in the size pointer PT. Is displayed on the display 22, or when there is registration dot pattern data, the size pointer value stored along with the dot pattern data is set in the size pointer PT, and Is displayed (S35). For example, when the registration dot pattern data does not exist, the start address α of the default size item “M” is set in the size pointer value PT as shown in FIG. 5, and as shown in FIG. The registration data input screen for the default size of 32 dots is displayed on the display 22.

Here, at the left end of the display 22,
An external character pattern display area D is provided. In the external character pattern display area D, 32 dots can be displayed in the vertical direction, and the display area D can be displayed in the horizontal direction by expanding or reducing the display area D by the number of dots of the current size. Therefore, above the right end of the display 22, there is provided a display range instruction area E which indicates the display range of the external character pattern display area D with respect to the size of the dot pattern of the current size in reverse video. That is, in the case of the size "M", since both the vertical and horizontal dots are 32 dots, the entire external character dot pattern of the size "M" can be displayed collectively. Here, when the registration dot pattern data exists in the registration data memory 42, the dot pattern data is displayed in the external character pattern display area D. The symbol k is a dot cursor for drawing a character pattern.

Next, when the enlargement / reduction key is operated (S36 / S37: Yes), pattern data enlargement / reduction processing control is executed (S38), and then S35 is executed. The enlargement / reduction processing control will be briefly described.
T is incremented by one, and the next size item in the size / dot number correspondence table TB is designated, and the size pointer value PT is decremented by one by operating the cursor up key, and the previous size item is designated. The registration dot pattern enlarged or reduced to this size is stored in the creation data buffer 44, and the registration dot pattern is stored in the size pointer value P in S35.
The external character pattern display area D having a size based on T is displayed.

Next, when a pattern creation key such as a cursor movement key, a shift key or a function key is operated (S36: Yes, S37: No, S39: Ye)
s) The drawing process control is executed (S40), and the process returns to S36. Briefly describing this drawing process control, when the cursor movement key is operated, the dot cursor k is moved in a direction corresponding to the type of the cursor movement key, and when the shift key or function key is operated, the dot data is deleted. The drawing data of “1” or “0” is created, and this drawing data is stored in the creation data buffer 44 and displayed in the external character pattern display area D. For example, as shown in FIG. 13, when a dot pattern of an external character G1 which is an illustration character is drawn, the dot pattern data of the external character G1 is stored in the creation data buffer 44 and the external character pattern display area D
Will be displayed.

Next, when the execution key is operated (S
36: Yes, S37 / S39: No, S41: Yes
s) Pattern data for storing the registration dot pattern data in the creation data buffer 44 in the registration data memory 42 in association with the size pointer value and the registration number specified by the registration number setting control (not shown). A registration process is executed (S42), this control ends, and the process returns to S11 of the tape print control. However, when the cancel key is operated (S36: Yes, S37.S
39 · S41: No, S43: Yes), and end processing such as clearing the registration dot pattern data in the creation data buffer 44 is executed (S44), and similarly, the process returns to S11 of the tape print control.

Next, when the print key is operated (S
11: Yes, S12, S15, S17, S19: N
o, S21: Yes), print processing control (see FIG. 9) is executed (S22). Here, when this print processing control is started, as shown in FIG. 15, the size data SZ (LL), alphabetic characters "A", "g", external characters "* 1", Code data of the external character “* 2”, size data SZ (S), and character “B” are stored in this order, and these characters and external characters are displayed on the document input screen of the display 22 as shown in FIG. It is assumed that

When this control is started, first, the head address of the text memory 41 is set to the text pointer XP (S50), and the development reference position calculation processing control (FIG. 10)
Reference) is performed (S51). When this control is started, first, the maximum size is searched based on the plurality of size data stored in the text memory 41, and the maximum size data is stored in the size memory 45 (S7).
0). Then, the base line position KL at the maximum number of vertical dots D is calculated (S71). That is, the ratio of the upper height H1 to the lower height H2 with respect to the base line (base line) is generally set to a ratio of "7: 1". Then, the base line position KL at the vertical dot number D of the maximum size “LL” is calculated.

In the print buffer 46, when the number D of vertical dots of the maximum size is arranged so that the upper margin TY and the lower margin BY are equal, the print buffer corresponding to this base line position KL The development reference position TK on 46 is calculated (S72), this control ends, and the process returns to S52 of the print processing control. That is, three types of sizes “LL”, “M”, and “S” in the text memory 41
Is the maximum size of “LL” and the number of vertical dots D is 64 dots. Therefore, as shown in FIG. 16, based on the height ratio, the base line position KL for the number of vertical dots D (64 dots) Upper height H1 (56 dots) and lower height H
2 (8 dots) are obtained, and the base line position KL when the upper margin TY and the lower margin BY are each 32 dots.
Is obtained from the lower end of the print buffer 46 corresponding to the dot pattern TK (40 dots). However, the upper end of the number D of vertical dots of the maximum size is the upper end position TL, and the lower end is the lower end position BL.

Next, the code data pointed by the text pointer XP is read out. If the code data is size data (S53: No), the size data is stored in the size memory 45 (S67) and the text pointer is read. XP is incremented by one (S5
9) Return to S52. On the other hand, when the read code data is an external character code (S53 / S54: Yes), a virtual external character base line position K provided near the lower part of the external character pattern
L is calculated (S55). For example, as shown in FIG. 17, in the dot pattern data of the external character G1 registered with the size “M”, the base line position KL and the upper height H are determined based on the height ratio and the number of vertical dots D (32 dots). (28 dots) and the lower height h (4 dots) are obtained.

Next, when this character has the maximum size (S5)
6: Yes), and although not the maximum size, the baseline flag KF
Is set and the baseline is aligned (S56: N
o, S60: Yes), the dot pattern data is developed in the print buffer 46 by matching the external character base line position KL with the development reference position TK (S57). When the document data still exists in the text memory 41 (S
58: Yes), the text pointer XP is incremented by one (S59), and the process returns to S52. By the way, when the read code data is an alphabet character code other than the external character (S53: Yes, S54: No), S5
Step S56 and subsequent steps are executed by skipping step 5.

For example, as shown in FIG. 18, first, alphabetic characters "A" and "g" having a size "LL" are dot-pattern-developed in the print buffer 46 with their base line position KL aligned with the development reference position TK. Then, the dot pattern data of the external characters G1 and G2 of the size "M" are developed in the print buffer 46 with their external character base line position KL aligned with the development reference position TK, and the alphabetic characters "B" of the size "S" are further developed. Are developed in the same manner by adjusting the base line position KL to the development reference position TK.

Next, when the read character is not the maximum size and the upper end flag TF is set and the upper end is aligned (S56, S60: No, S61: Yes), the vertical position of the maximum size is set as the base line position moving amount ΔD. The number of dots is obtained by subtracting the upper height H of the read character from the upper height H1 of the number of dots D (S62), and the baseline position KL of the read character is shifted by the baseline position shift amount Δ with respect to the development reference position TK.
The image is moved upward by D and developed in the print buffer 46 (S63), and S58 and subsequent steps are executed. For example,
As shown in FIG. 19, the character “A” having the maximum size “LL”
g ”is the same as the baseline position KL, but the external characters G1, G
2 and the base line position KL of the character "B" are respectively moved upward with respect to the expansion reference position TK by the obtained base line movement amount ΔD, and are image-developed in the print buffer 46. These external characters G1, G2 and the character ""B" is aligned with the upper end position TL of the character "Ag".

Further, when the read character is not the maximum size and the lower end flag BF is set and the lower end is aligned (S56, S60, S61: No), the base line position shift amount ΔD is set to the maximum size vertical dot number D Lower height H2
Is obtained by subtracting the lower height h of the read character from (step S64), and the base position KL of the read character is moved downward by the base position moving amount ΔD with respect to the development reference position TK. The image is developed in the print buffer 46 (S65), and S58 and subsequent steps are executed. For example, FIG.
As shown in the figure, the baseline position KL of the character "Ag" of the maximum size "LL" is kept as it is, but the baseline positions KL of the external characters G1, G2 and the character "B" are expanded by the obtained baseline position movement amount ΔD. The image is developed in the print buffer 46 while being moved downward with respect to the reference position TK.
1, G2 and the character "B" are aligned with the lowermost page TL of the character "Ag".

The document data is stored in the text memory 41.
(S58: No), based on the dot pattern data developed in the print buffer 46,
A printing process for printing on the printing tape 5 is executed (S6).
6), this control ends, and the process returns to S11 of the tape print control. As a result, at the time of base line alignment, as shown in FIG. 21, the character "Ag", the external character G1, and the external character G
2. The character "B" is printed such that the base line positions KL set to the same are at the same level, so that the character can be printed with good appearance. In addition, when the upper end position is aligned, as shown in FIG.
1 and G2 are printed in alignment with the upper end position of the maximum size character "Ag". Further, when the lower end position is aligned, FIG.
As shown in FIG. 3, the character "B" and the external characters G1 and G2 are printed in alignment with the upper end position of the character "Ag" of the maximum size. Further, in the tape print control, when keys other than the document creation key, the character size key, the alignment position setting key, the external character key, and the print key are operated (S11: Yes,
(S12 / S15 / S17 / S19 / S21: No), a process corresponding to the operated key is executed (S23), and S
Return to 11.

As described above, the text memory 41
The dot pattern data of the alphabetic character is expanded in the print buffer 46 with respect to the code data of the alphabetic character and the code data of the external character read from the external character. Since the development base line KL is developed in the print buffer 46 so as to be at the same level via the development reference position TK, the printing position of the external character is printed somewhat lower than the lowercase alphabet, In particular, lower-case alphabets including lower-case alphabets protruding below the base line, such as "g" and "j", and external characters can be printed in a well-balanced and attractive manner. Further, it is possible to easily perform the alignment printing in which the alphabet and the external character are aligned with the upper end position and the lower end position of the maximum character. Further, when the external character is to be subjected to italic character modification, it is possible to tilt the upper external character portion to the right and the lower external character portion to the left with respect to the external character base line KL. In this case, italic modification It is possible to print with good appearance without narrowing the pitch between characters between the external character and the adjacent character.

Here, the correspondence between each means described in the claims (claim 1) and the configuration in the above-described embodiment will be described. S55 and the control device C, which correspond to the baseline control means are S57 of the print processing control program and the control device C.

The height ratio (H1 / H2) of the upper and lower sides of the alphabet base line KL of the alphabet characters is not limited to "7: 1", and various ratios can be used according to the typeface. . Note that, for characters and symbols such as kanji and hiragana, dot pattern data corresponding to a plurality of sizes is used instead of outline phone data.
