DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS The present invention will be specifically described below with reference to an embodiment shown in the drawings. This embodiment is an example applied to a Japanese personal word processor.

Configuration of the Embodiment FIG. 1 shows a block circuit diagram of this word processor. On the keyboard of this input unit 1, in addition to character input keys such as Kana characters, Roman characters, numbers, and Kanji conversion keys,
An up / down cursor movement key KA, a vertical double key KB, a double angle key KC, a cancel key KD, an execute key KE, and a print key KF are provided. Here, the vertical double key KB is a key for vertically designating a designated character with respect to a standard size (full-width size), and the double-width key KC is a key for horizontally designating a designated character with respect to a standard size. The release key KD is a key for releasing the enlargement setting mode and returning to the normal mode, the execution key KE is a key for executing the enlargement setting, and the print key is a key for starting the printing of the created text data. Is. Then, the key code output from the input unit 1 corresponding to the operation key is the CPU (central processing unit) 2
And specify the key processing program accordingly.

The CPU 2 controls various operations of the word processor, and executes input processing, arithmetic processing, Chinese character conversion processing, character enlargement processing (free-double-width processing) and the like. Then, the CPU 2 writes the character code, the vertical double-width code, and the horizontal double-width code corresponding to the operation key from the input unit 1 in the sentence memory 3 in the order of input. The text memory 3 is composed of a large-capacity RAM (Random Access Memory), and its writing and reading operations are controlled under the control of the CPU 2. The character codes read from the text memory 3 are fetched by the CPU 2. , CPU
It is given to a ROM (read only memory) 4 under the control of 2. The ROM 4 stores, for example, a character generator CG that stores a character pattern in which one character is composed of 16 × 16 dots corresponding to each character, a message table MT that stores various message data, and a program that stores various programs for system control. It has a configuration including a memory PM. And the character generator C
Dot pattern (character pattern) converted and output from G
Are sent to the display memory 5 via the CPU 2. The display memory 5 stores the character pattern from the CPU 2, the content of which is sent to the display driver 6 and converted into a display drive signal, which is then displayed on the display device 7. Here, the display device 7
Is composed of a liquid crystal display device and displays characters and the like in accordance with a dot matrix driving method, and its display area has a structure of two rows above and below.

Further, when printing the contents of the text memory 3, the CPU 2 discriminates whether it is a full-width character or an enlarged character in accordance with the code fetched from the text memory 3 into the CPU 2, and if it is a full-width character, it is output from the character generator CG. The character pattern is sent as it is to the printing unit 9 via the print control unit 8 and printed in full-width size. When the character is an enlarged character, the character pattern from the character generator CG is used as a CP.
It is sent to the enlarged pattern generation unit 10 in U2. The enlargement pattern generation unit 10 enlarges a character pattern according to the enlargement information from the enlargement data memory 11, and the enlarged character pattern is sent to the printing unit 9 via the print control unit 8 to be enlarged. Printed in size. The printing unit 9 is composed of a thermal transfer type thermal printer, and prints data in the print control unit 8 in a dot pattern.

A RAM 12 for storing various information for free enlargement processing is bidirectionally connected to the CPU 2. The RAM 12 stores the following information. That is, NOWPA: the current page top address of the text memory 3 NOWLA: cursor line top address of the text memory 3 TXCSR: cursor digit position DSPTC: display start digit position when vertical double angle is set NOWLN: displayed current line number DSPLN: display Upper row number TNA: Current row start address corresponding to the above NOWLA TTX: Cursor digit position corresponding to the above TXCSR TDT: Display start column position corresponding to the above DSPPT TNL: Current row number corresponding to the above NOWLN TDL: Above the above DSPLN Corresponding display Upper row number XWD: Double horizontal size YWD: Double vertical size COL: Maximum number of digits per line according to text format CSR: Cursor digit position of target line when vertical double angle is set

Operation of the Embodiment First, the operation in the case of setting the input character to a free-size double angle of the free size both vertically and horizontally will be described. Fig. 2 (1)-
(5) is a diagram showing an example of a key operation at the time of setting a vertical double angle and a display example corresponding to the key operation. Then, FIG. 2A shows a display example after the horizontal double angle is set. In this case, the horizontal double angle setting is
This is done by sequentially operating the double angle keys as shown in (1) to (4). First, as shown in FIG. 3 (1), the cursor is set at the character position to be enlarged in the sentence data written in the sentence memory 3, for example, "this character is enlarged". Now, it shows the state that the cursor is set to the character of "enlarged", and when the double-width key is operated in this state,
As shown in FIG. 3 (2), each character code on the left side of the character "enlarged" specified to be enlarged is sequentially shifted one digit to the left, and the cursor digit is moved one digit to the left to double the angle. Code is written. As a result of performing such an operation each time the double-size key is operated, the storage state of the text memory 3 becomes as shown in FIG. 3C when the double-size key is operated for the second time, and further when the third-time operation is performed. As shown in FIG. 3 (4). Therefore, if you operate the double-width key 3 times, the double-width code will be 3
Will be written individually. In this case, the quadruple width is set including the three double-width codes and the character code "widening" designated for enlargement.

After setting the double-width code in this way, the vertical double-width is set. In this case, after operating the vertical double-width key, the cursor movement key "↑" is operated to update the vertical double-width, and when the desired vertical double-width setting is completed, the execute key is operated (FIGS. 2 (2) to (5)). reference). Then, the flow of FIG. 4 is started by operating the double-height key. That is, in FIG. 4, when the vertical double-width key is operated, after the vertical double-width setting is completed, a process of saving the return information is executed to restore the normal display (step S1). That is, here, as the return information, the current line head address (TNA), the cursor digit position (TTX), the display start digit position (TDT), the current line number (TNL), and the display upper row number (TDL). , Each of these return information is RAM1
The data is written in the corresponding area in 2 and saved until the vertical double angle setting process is completed. When such a return information setting process is completed, an initialization process (step S2) for each information required in the vertical double angle setting process is performed. That is,
"1" is set as the double width size (XWD), the current line start address (TNA) is transferred as the cursor line start address (NOWLA), and the maximum number of digits (COL) according to the sentence format is set. Double size (YW
"2" is set as D), and the cursor digit position (CSR) of the target line is further set.

When the above initialization is completed, the contents of the text memory 3 corresponding to the current cursor digit position are read and it is checked whether the read code is a double-width code (steps S3 and S4). Now, Figure 2 (1)
Since the cursor position before the vertical double-width key is operated is set to the position corresponding to the double-width code set last as shown in (4), the read code is determined to be the double-width code in step S4. In this case, the cursor digit moves to the right by one character, that is, the increment processing for incrementing the cursor digit position of the target line by +1 is executed. Then, the double angle size in the horizontal direction (XWD) is incremented by 1 in accordance with the detection of the double angle code (step S6). Here, since the initial value "1" is set for the double angle size (XWD), the value becomes "2" with the first double angle code detection. Next, the cursor digit position (CSR) of the line of interest is compared with the maximum number of digits (COL) in the format, and it is checked whether or not the cursor has been moved to a position that exceeds the maximum digit per line according to the text format. (Step S7). If not, the process returns to step S3 to detect the double-width code, and if there is the double-width code, the process of counting the double-width size is executed while moving the cursor digit to the right by one character. Therefore, the double-width size (XW
D) is “3”, and the double angle size (XWD) is “4” in the third double angle code detection. When the vertical double-width key is operated in this way, the text memory 3 is moved from the cursor position at that time.
Is sequentially read, and the double-width size is counted until a code other than the double-width code appears. Such counting operation is performed within the range of the maximum number of digits in the format. When the maximum digit excess is detected, the vertical double angle setting flow is exited.

When a code other than the double-width code is detected, the double-width setting display (step S8) is executed,
Text is displayed in the upper display area of the display device 7, and a message quantitatively indicating the enlargement size is displayed in the lower display area. That is, as shown in FIG. 2A, as the display contents associated with the operation of the vertical double key, the text data corresponding to the contents of the text memory 3 is read out in the upper display area and written into the display memory 5 to be written into the driver 6 Converted to display drive signal with

[Outside 1] Expanded ... is displayed. In this case, the cursor is located at the "wide" display digit. In the lower display area, ROM4
Message table MT of "free double size"

[Outside 2] Are read out from the RAM 12, and the vertical double-width size YWD (initial value “2”) and horizontal double-width size XWD (set value “4”) are read out from the RAM 12 and written into the display memory 5, respectively. "Free double angle""2 x 4 times"
Is displayed. Next, a state of waiting for a key input from the operator is set (step S9). Here, the valid keys are the execution key (step S10) and the release key (step S1).
1), cursor movement key

[Outside 3] (Step S12), cursor movement key

[Outside 4] (Step S13). Now, move the cursor key to update the double height

When [External 3] is operated, this is detected in step S12, and the process proceeds to step S17, where the start address of the line one line above (the line before) the current line is obtained, and the cursor line start address NOWLA is stored in RAM12. Is set as. Then, as a result of changing the cursor line leading end address NOWLA as described above, it is checked whether the value is within a predetermined range (step S15). That is, the RAM 12
Among the current row head address TNA, the cursor row head address NOWLA, and the current page head address NOWPA, there is a relationship of TNA> NOWLA ≧ NOWPA, in other words, the cursor movement key in this case.

The operation to check whether the cursor line (target line) start address is within the current page by [Outside 3] operation, and to prevent the double-width setting from extending to the previous page. Proceed to S16, cursor move key

A process for changing the vertical multiple is performed in accordance with the operation of [External 3], and the vertical double size YWD in the RAM 12 is incremented by 1 to become "3". Then, the process returns to step S8 and the display process is performed.

[Exterior 3] The display contents are as shown in FIG. 2 (3) according to the first operation, and the message display is "double angle 3 × 4".
Then, the key input waiting state is entered (step S9), and the cursor movement key is pressed again.

When [External 3] is operated, the same operation as described above is repeated. After the cursor line start address is changed, if the address is within the current page, the increment process for increasing the vertical multiple is executed. It returns to step S8. Therefore, the cursor movement key

[Exterior 3] With the second operation, as shown in FIG. 4 (4), the message content becomes “free double angle 4 × 4 times”. This makes it possible to visually confirm that the setting of the desired vertical multiple has been completed. The setting of the double-height size is performed within the range of the current page top address NOWPA, and when it exceeds the address, the fact is detected in step S15 and the process returns to step S8, and the increment processing of the double-height size is prohibited. . On the other hand, cursor movement key

When [External 4] is operated, this is detected in step S13, and the process proceeds to step S14, the start address of the line (next line) immediately below the current line is calculated, and the cursor line start address is stored in the RAM 12. Set as NOWLA. Then, in step S15, it is checked whether or not the changed cursor row start address NOWLA is within a predetermined range. As a result, if it is within the predetermined range, the vertical double-width size YW
After the process of decrementing D by 1 is executed, the process returns to step S8. Therefore, the preset double-width size is

The vertical double size is decremented by 1 each time [External 4] is operated, so if you set a large vertical multiple by mistake, the cursor movement key

You can correct it with the operation of [Ex. 4]. In addition,
This correction is performed within the range of the current row head address TNA, and when it exceeds the range, the process returns from step S15 to step S8 and the vertical multiple change processing is prohibited.

Then, when the setting of the desired vertical double angle is completed and the execute key is operated, that is the step S1.
When it is detected as 0, the process proceeds to step S18, and the vertically doubled code is written in the text memory 3. In this case, as shown in FIG. 5, the process of writing the vertically-doubled code for the horizontally-doubled size XWD in the horizontal direction in the text memory 3 is repeated for the vertically-doubled size YWD-1 line to fill the enlarged space with the vertically-doubled code. Will be done. As a result, the "enlarged" character is 4
This means that the size has been set to × 4 times. Next, the information saved in step S1, that is, the current row start address TNA, the cursor digit position TTX, the display start digit position TDT, the current row number TNL, and the display upper row number TD.
NOWLA and TXCS in RAM 12 corresponding to L respectively
It is returned as R, DSPTC, NOWLN, DSPLN (step S19). As a result, the display state is returned from the vertical double-width setting to the normal state. Then, the cursor is moved to the right by one digit to set the cursor to the next digit (step S20). FIG. 2 (5) shows the display state when the normal state is returned by the operation of the execution key.
Lines are displayed and the cursor is set to the double-width code position for the next character. In this way, when the enter key is operated after the vertical double-width setting is completed, the cursor is automatically set to the next digit by moving the cursor right, so it is possible to continuously set the vertical double-width setting for the next character. it can. When the cancel key is operated, the vertical double angle setting flow is exited (step S21).

Next, in printing the data created in the text memory 3, the operation when the print key is operated is shown in FIG.
It will be described according to the flow shown in. When the print key is operated, first, it is determined whether the enlarged print operation is in progress.
It is checked depending on whether the enlargement information is stored in 1 (step S31). If the enlargement printing operation is not currently being performed, the code is read from the text memory 3, and then it is checked whether the final code of the text memory 3 has been read (steps S32 and S33). If all the contents of the text memory 3 are not printed, it is checked whether the code read from the text memory 3 is an enlarged code, that is, a double-height code or a double-height code (step S34). Here, if the code is not the enlarged code, characters are printed in the normal full-width size. In this case, the character code read from the text memory 3 is given to the character generator CG in the ROM 4 under the control of the CPU 2, converted into a full-width character pattern, and sent to the printing unit 9 via the print control unit 8. , Double-byte characters are printed.

In the case of the enlargement code, the enlargement ratio in the vertical and horizontal directions is calculated based on the horizontal double-width size XWD and the vertical double-width size YWD in the RAM 12, and the enlargement information is added to the enlargement data together with the character code designated for enlargement. It is stored in the memory 11 (step S36). Then, according to the contents of the expanded data memory 11, the character generator C
The character pattern from G is magnified and magnified and printed by the printing unit 9 for one line (step S37). Then, it is checked whether or not the enlarged printing is finished. If the enlarged printing is not finished, the process returns to step S31 and the same processing as described above is performed until the enlarged printing is finished. When the enlargement printing is completed, the corresponding contents of the enlargement data memory 11 are reset in step S39, and then the process returns to step S31.

FIG. 7 and FIG. 8 show printing states according to the setting contents of the text memory 3. That is, FIG. 7 (A) shows the contents of the text memory 3 when the horizontal double angle is set to 4 times, and FIG. 7 (B) shows the printing state according to this, and the character of "wide" is 4 times horizontally. It will be expanded to the size that was set. Further, FIG. 8A shows the contents of the text memory 3 when the horizontal double angle is set to 4 times and the vertical double angle is set to 4 times, and FIG.
In the printing state corresponding to this, the character of "expansion" is enlarged to 4x4 times the full width. As described above, in the present embodiment, it is possible to perform enlarged printing of characters with the enlargement ratio freely set for each character.

In the above embodiment, as shown in FIG. 5, the vertical double-width code is filled, but by writing the vertical double-width code on the finally set double-width code,
Double-width code (including character code) and vertical double-width code L
The text memory can be saved by arranging them in a character shape and writing the next character code using the empty area between them.

[0020]

According to the present invention, the enlargement ratios in the horizontal direction and the vertical direction can be freely specified individually for desired character data arbitrarily specified by the cursor among a plurality of character data. After this designation, the enlargement ratio can be changed and designated as needed, and various types of character output with various character sizes can be output. In addition, since the contents of this designation and change are immediately displayed as guidance in accordance with the designation, prior to the actual enlargement output, the above-mentioned arbitrary magnification in the horizontal direction or the magnification in the vertical direction is the desired magnification. It is possible to confirm on the display screen whether or not it has been changed, or whether or not the magnification can be changed to a desired magnification. Further, in the storage unit for storing the plurality of character data, for the character data for which the enlargement ratio is specified, information indicating the lateral magnification and the vertical magnification is stored in association with the character data, When the contents stored in the storage means are read out and expanded into a character pattern and printed out, the character data for which the enlargement ratio is specified can be printed out at the corresponding horizontal and vertical magnifications, and non-enlarged characters can be output. And enlarged characters can be mixed and printed.
