Description

Description: TECHNICAL FIELD The present invention relates to a text output device that develops and outputs each of a plurality of character data into a corresponding character pattern.

[Prior Art] Conventionally, in a Japanese personal word processor,
By operating the double-size key when entering a sentence, the characters to be emphasized can be enlarged and printed.

Further, there is also a display control device capable of uniformly enlarging a plurality of entire character data displayed on the display screen in the horizontal and vertical directions for each character data at a desired magnification.

[Problems to be Solved by the Invention] However, in the above-mentioned personal word processor, the character size that can be designated to be enlarged by the operation of the double-width key is predetermined, and it is possible to print only in the predetermined size. It was

Further, in the display control device, the object that can be magnified is limited to the entire plurality of character data, and only the desired character data among the plurality of character data is displayed in the desired horizontal magnification and in the desired vertical direction. It could not be magnified.

An object of the present invention is to make it possible to individually specify and output the enlargement factors in the horizontal and vertical directions for desired desired character data on a display screen displaying a plurality of character data. is there.

[Means for Solving the Problems] Means of the present invention are as follows.

Text data storage means for storing text data composed of a plurality of character data, display means for displaying the text data stored in the text data storage means on a display screen, and the text data displayed on the display screen Character designating means for designating a desired arbitrary character data position to be magnified with a cursor, and a magnification factor of an arbitrary integer multiple in the horizontal direction and vertical direction with respect to the character data designated by the cursor. Magnification specifying means for individually specifying an enlargement ratio of an arbitrary integer multiple, horizontal magnification information indicating the horizontal magnification specified by the magnification specifying means, and vertical magnification information indicating the vertical magnification. And a guidance information based on the lateral magnification information and the vertical magnification information temporarily held by the holding means, and the guidance information based on the lateral magnification information to the enlargement target character data. On the display screen for displaying the text data, display control means for controlling the display together with the display of the text data, and on the display screen so that it can be seen that the guidance is for the magnification in the horizontal and vertical directions. When a predetermined confirming operation is performed after the guidance is displayed, the enlargement magnification information based on the lateral magnification information and the vertical magnification information held in the holding means is converted into the enlargement information in the sentence data storage means. The character data is stored in association with the storage position of the target character data, and when the predetermined release operation is performed after the guidance is displayed, the lateral magnification information and the vertical magnification information held by the holding means are stored. Storage control means for stopping storage of the enlargement magnification information based on the sentence data storage means,
The text data stored in the text data storage means is read, each character data included in the text data is expanded into a corresponding character pattern and output, and at this time, the enlargement magnification is applied to the read character data. If the information is not stored in association with each other, the character pattern corresponding to the character data is output in the same size, and the enlargement magnification information is associated with the read character data. If stored, the output means includes a character pattern corresponding to the character data, which is converted into a pattern enlarged in the horizontal and vertical directions at respective magnifications in accordance with the enlargement magnification information and is output.

[Operation] The operation of the means of the present invention is as follows.

The text data stored in the text data storage means is displayed on the display screen, and the position of any desired character data to be enlarged on the text data displayed on this display screen is designated by the cursor. For the character data designated by this cursor, the enlargement ratio of an arbitrary integral multiple in the horizontal direction and the enlargement ratio of an arbitrary integral multiple in the vertical direction are individually specified. The specified horizontal magnification information indicating the horizontal magnification and the vertical magnification information indicating the vertical magnification that are specified are temporarily stored in a holding unit, and the temporarily stored horizontal magnification information and As can be seen, the guidance information based on the vertical magnification information is guidance on the horizontal and vertical enlargement ratios for the character data to be enlarged.
It is displayed together with the display of the text data on the display screen that displays the text data. Then, when a predetermined confirming operation is performed after the guidance is displayed on the display screen, the enlargement magnification information based on the lateral magnification information and the vertical magnification information held in the holding means is changed to the sentence The character data to be enlarged is stored in the data storage means in association with the storage position,
When a predetermined release operation is performed after the guidance is displayed, the enlargement magnification information based on the lateral magnification information and the vertical magnification information held in the holding means is stored in the text data storage means. Abort. Then, the text data stored in the text data storage means is read, and each character data included in the text data is expanded into a corresponding character pattern and output. At this time, the above-mentioned character data is read with respect to the read character data. If the enlargement ratio information is not stored in association with the enlargement ratio information, the character pattern corresponding to the character data is output in the same size, and the enlargement ratio information is associated with the read character data. If it is stored in the memory, the character pattern corresponding to the character data is converted into a pattern enlarged in the horizontal direction and the vertical direction at each magnification according to the enlargement magnification information and is output.

Therefore, according to the present invention, it is possible to arbitrarily specify the enlargement ratio in the horizontal direction and the vertical direction for the character data specified by the cursor on the text data, and the information based on this specification is associated with the specified character data. It can be easily stored in the text data storage means.

When designating the enlargement magnification, the designation information is not stored in the text data as it is, but the designation information is once held and displayed as a guidance, and the user can perform any operation after confirming the guidance display. Since the text data can be stored in the text data, even if there is a mistake in the enlargement ratio that should be specified, or if there is a need to cancel the enlargement ratio specification, the storage state in the text data will be affected. Without giving, the contents of designation of the enlargement ratio can be corrected or the designation of the enlargement ratio can be stopped at any time while the guidance is being displayed.

[Embodiment] The present invention will be specifically described below based on an embodiment shown in the drawings. This embodiment is an example applied to a Japanese personal word processor.

Configuration of Embodiment FIG. 1 shows a block circuit diagram of this word processor. On the keyboard of this input unit 1, kana characters,
Character input keys such as Roman letters and numbers, Kanji conversion keys, etc.
Up and down cursor movement key KA, vertical double key KB, double angle key KC,
A release key KD, an execution key KE, and a print key KF are provided. Here, the vertical double key KB is a key for vertically enlarging a specified character with respect to the standard size (double-byte size), and the double-width key KC is for horizontally enlarging a specified character with respect to the standard size. Key, release key KD is a key for canceling the enlargement setting mode and returning to the normal mode, execution key KE is a key for executing the enlargement setting, 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 sent to the CPU (central processing unit) 2 and the key processing program corresponding to it is designated.

The CPU 2 controls various operations of this word processor, and executes input processing, arithmetic processing, Kanji 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 stored in the CPU 2
And is given to the ROM (read only memory) 4 under the control of the CPU 2. The ROM 4 is, 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 is configured to have a memory PM. And the character generator
Dot pattern (character pattern) converted and output from CG
Are sent to the display memory 5 via the CPU 2. 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 the dot matrix driving method, and the display area thereof has a structure extending vertically into two rows.

Also, when printing the contents of the text memory 3,
According to the code fetched by the CPU2 from the CPU2, the CPU2 determines whether it is a double-byte character or an enlarged character. Print in size.
Also, if it is an enlarged character, a character generator
Enlarged pattern generator 10 in CPU2 for character patterns from CG
Send to. This expansion pattern generator 10 is an expansion data memory
The character pattern is enlarged according to the enlargement information from 11, and the enlarged character pattern is sent to the printing unit 9 via the print control unit 8 and printed in the enlarged size. The printing unit 9 is composed of a thermal transfer type summary printer, and prints the data in the print control unit 8 in a dot pattern.

In addition, the CPU2 stores various information for free enlargement processing.
RAM12 is bidirectionally connected. The RAM 12 stores the following information. That is, NOWPA: Start address of current page of text memory 3 NOWLA: Start address of cursor line of text memory 3 TXCSR: Position of cursor digit DSPTC: Position of display start digit when vertical double angle is set NOWLN: Current line number displayed 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 DSPTC TNL: Current row number corresponding to the above NOWLN TDL: Above DSPLN Corresponding display Upper row Number XWD: Double horizontal size YWD: Double vertical size COL: Maximum number of digits per line according to the text format CSR: Cursor digit position of the line of interest when double vertical setting is set Example operation First An operation when the input character is set to a free-size double-size of both vertical and horizontal will be described. Figure 2 (1) ~
(5) is a diagram showing a key operation row and a display example corresponding to the key operation row at the time of setting the vertical double angle. FIG. 2 (1) shows a display example after setting the horizontal double angle. In this case, the horizontal double angle setting is performed by sequentially operating the double angle keys as shown in FIGS. First, as shown in FIG. 3 (1), the cursor is set at a character position to be enlarged in the sentence data written in the sentence memory 3, for example, "this character is enlarged". Now, a state is shown in which the cursor is set to the character "enlarged", and if the double-width key is operated in this state, as shown in FIG. The character code is sequentially shifted one digit to the left, the cursor digit is moved one digit to the left, and the double-width code is written in this cursor digit. As a result of such an operation being performed each time the double-size key is operated, the storage state of the text memory 3 becomes as shown in FIG. 3 (3) in the second operation of the double-size key, and the third operation is performed. Then, it becomes as shown in FIG. Therefore, if the double-width key is operated three times, three double-width codes are continuously written on the left side of the enlargement-designated character "wide". 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 (second
See Figures (2) to (5). 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 return information, the current line start address (TNA), cursor column position (TTX), display start column position (TD
T), current row number (TNL), display top row number (TDL)
The return information is written in the corresponding area in the RAM 12 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, double-width size (XW
"1" is set as D) and the current line start address (TN
A) is transferred as the cursor line start address (NOWLA), the maximum number of digits (COL) according to the sentence format is set, and the vertical double size (YWD) is set to "2". Position (CSR) is set.

Then, when the above-mentioned initialization is completed, the contents of the text memory 3 corresponding to the current cursor digit position are read, and it is checked whether or not this read code is a double-width code (steps S3, S4). Now, as shown in FIG. 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,
In step S4, the read code is determined to be the double-width code. In this case, the cursor digit moves 11 characters to the right, that is,
Increment processing is performed to increment the cursor column position of the line of interest by +1. Then, with the detection of the double-width code, the horizontal double-width size (XWD) is incremented by 1 (step S6). Since the double-width size (XWD) is set to the initial value "1", the value becomes "2" with the first double-width code detection. Next, the cursor column position (CSR) of the line of interest
Is compared with the maximum number of digits in the format (COL), and it is checked whether or not the personal computer has been moved to a position where the maximum number of digits per line is exceeded according to the text format (step S7). If it does not exceed, 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 while moving to the right by one character of the cursor digit is executed. Therefore, the double-width code (XWD) becomes "3" at the second double-width code detection, and the double-width size (XWD) becomes "4" at the third double-width code detection. When the vertical double-width key is operated in this manner, the contents of the text memory 3 are sequentially read from the cursor position at that time, and the double-width size is counted until a code other than the double-width code appears. Is performed within the maximum number of digits in the format. When the maximum digit excess is detected, the vertical double angle setting flow is exited.

Then, when a code other than the double-width code is detected, the double-width setting display (step S8) is executed, and a message quantitatively indicating the text in the upper display area of the display device 7 and the enlarged size in the lower display area is displayed. Is displayed. That is, as shown in FIG. 2 (1), the display contents accompanying the operation of the vertical double key are
Text data corresponding to the contents of the text memory 3 is read in the upper display area, written in the display memory 5, and converted into a display drive signal by the driver 6. Is displayed. In this case, the cursor is located at the "wide" display digit. In addition, in the lower display area, from the message table MT of ROM4, "double angle" Are read out from the RAM 12 and double-width YWD
(Initial value "2"), horizontal double-width size XWD (set value "4") are read out and written in the display memory 5, respectively, and "free-double-width" and "2x4" are set via the driver 6. Is displayed.

Next, a state of waiting for a key input from the operator is set (step S9). Here, the valid key is the execution key (step S1
0), release key (step S11), cursor move key ▲
[↑] ▼ (step S12), cursor move key ▲ [↓]
▼ (Step S13). Now, when the cursor movement key ▲ [↑] ▼ is operated to update the vertical double angle, that is detected in step S12 and the process proceeds to step S17, and the line is one line higher than the current line (front line). The start address of the cursor is calculated and set in the RAM 12 as the cursor line start address NOWLA. 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 relation of TNA> NOWLA ≧ NOWPA is established among the current line start address TNA, the cursor line start address NOWLA, and the current page start address NOWPA in the RAM 12, in other words, in the present case, the cursor movement key By the operation of ▲ [↑] ▼, it is checked whether the start address of the cursor line (the line of interest) is in the current page, and it is a process to prevent the double-width setting from extending to the previous page. Proceed to step S16, and move the cursor key ▲ [↑] ▼
A process to change the vertical multiple is performed in accordance with the operation, and RAM1
The vertical double size YWD in 2 is incremented by 1 to become "3". Then, the processing returns to step S8, and the display processing is performed, so that the display content becomes as shown in FIG. 2 (3) in response to the first operation of the cursor movement key ▲ [↑] ▼, and the message display is "free-double-width". 3 × 4 times ”. Then, a key input waiting state is set (step S9). When the cursor movement key ▲ [↑] ▼ is operated again, the same operation as described above is repeated. After the cursor line start address change processing, if the address is within the current page, the vertical multiple is +1. The increment process is performed and the process returns to step S8. Therefore, by the second operation of the cursor movement key ▲ [↑] ▼, the display content becomes “free double angle 4 × 4 times” as shown in FIG. 4 (4). This makes it possible to visually confirm that the setting of the desired vertical multiple has been completed. The setting of this double-height size is done within the range of the current page top address NOWPA.
This is detected in step S15 and the process returns to step S8, and the double-height size increment processing is prohibited. On the other hand, when the cursor movement key ▲ [↓] ▼ is operated, the fact is detected in step S13, and the process proceeds to step S14 to obtain the start address of the line (next line) one below the current line. It is set in RAM12 as the cursor line start address NOWLA. Then, in step S15, it is checked whether the changed cursor line start address NOWLA is within a predetermined range,
As a result, if it is within the specified range, double-height size YWD-
After the processing of 1 is executed, the process returns to step S8. Therefore, the preset double-width size is decremented by 1 each time the cursor movement key ▲ [↓] ▼ is operated, so if the vertical multiple is set incorrectly, the cursor movement key ▲ You can correct it by the operation of [↓] ▼. This correction is made at the start address TNA of the current line.
Within the range of, and beyond that, step
The process returns from step S15 to step S8, and the vertical multiple change processing is prohibited.

Then, when the setting of the desired double-height angle is completed and the execution key is operated, this is detected in step S10 and the process proceeds to step S18, and the double-height code is written in the text memory 3. In this case, as shown in FIG.
This is because the process of writing the vertically doubled code for the horizontally doubled size XWD in the horizontal direction is repeated for the vertically doubled size YWD-1 line to fill the expansion space with the vertically doubled code. As a result, the character "enlarged" is set to a size of 4x4. 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,
NOWLA, T in RAM12 corresponding to the upper row number TDL
Returned as XCSR, DSPTC, NOWLN, DSPLN (step S
19). 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). Second
Figure (5) is the display state when the normal state is returned by the operation of the execution key, the message display showing the free double angle disappears, the contents of the text memory 3 are displayed for one line in both upper and lower display areas, 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 release key is operated, the vertical double-width setting flow is exited (step S2
1).

Next, when printing the created data in the text memory 3, the operation when the print key is operated will be described according to the flow shown in FIG. When the print key is operated,
First, whether or not the enlargement printing operation is being performed is checked according to whether enlargement information is stored in the enlargement data memory 11 (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 S3).
3). 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 vertical double-width code or a horizontal double-width 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.

Also, if it is an expansion code, double width size XW in RAM 12
D, vertical and horizontal enlargement ratios are calculated based on the double-height size YWD, and the enlargement information is stored in the enlargement data memory 11 together with the character code specified for enlargement (step S3
6). Then, the character pattern from the character generator CG is enlarged according to the contents of the enlarged data memory 11 and enlarged and printed for one line in the printing unit 9 (step S3).
7). Then, it is checked from the end of enlargement printing. If it is not the end of enlargement printing, the process returns to step S31 and the same processing as described above is performed until the end of enlargement printing. Then, when the enlarged printing is completed, the corresponding contents of the enlarged data memory 11 are reset in step S39, and then the process returns to step S31.

FIG. 7 and FIG. 8 show print states in the text memory 3 according to the set contents. 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 horizontal. It will be enlarged to 4 times the size. Also, the eighth
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. The character is enlarged to 4 × 4 times the full-width character. As described above, in the present embodiment, it is possible to print 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 used for filling. However, by writing the vertical double-width code on the finally set double-width code, the double-width code (including the character code) is obtained. The text memory can be saved by arranging the vertical double-width code and the L-shaped code and writing the next character code using the empty area between them.

[Effects of the Invention] According to the present invention, horizontal and vertical enlargement ratios can be arbitrarily designated for character data designated by a cursor on text data, and information based on this designation can be used to obtain information based on the designation. Can be easily stored in the text data storage means in association with.

When designating the enlargement magnification, the designation information is not stored in the text data as it is, but the designation information is temporarily held and displayed as a guidance, and any operation after confirmation of the guidance display is performed. Therefore, even if there is a case where the enlargement ratio that should be specified is incorrect or there is a case where it is necessary to cancel the enlargement ratio specification, etc. While the guidance is being displayed, the contents of designation of the enlargement ratio can be corrected or the designation of the enlargement ratio can be stopped at any time without giving the.

Furthermore, when the character data with the specified enlargement ratio is output in a pattern enlarged with the corresponding enlargement ratio, the enlargement information is stored in association with the character data on the sentence data. With reference to, it is possible to output characters in the enlargement pattern just by reading the character data and the enlargement information corresponding to the character data from the text data. At this time, naturally, enlargement is designated. A normal size character pattern of non-existing character data and a character pattern of the expanded size of the character data specified to be expanded can be mixed and output.
