Paper is fed.
[0027]
Next, the operation of the word processor having the above configuration will be described.
FIG. 3 is a flowchart showing key input processing in the word processor.
[0028]
FIG. 4 is a diagram showing the character size change setting contents in the word processor and the character size change state associated with the character key operation. FIG. 4A shows the change size, the number of change steps, the key operation time (change timing). (B) is a diagram showing a display example of changing the input character size accompanying the continuous operation of the character input key.
[0029]
First, as shown in FIG. 4A, when the change character size is set as a quadruple size on the enlargement side by operating the changeover switch A17, the change size data is stored in the size setting register 16d in the RAM 16.
[0030]
Also, as shown in FIG. 4A, when the changeover switch B18 is operated to set the number of character size change steps to three, the change step number is stored in the change step number register 16e in the RAM 16.
[0031]
Furthermore, when the character size change timing (key operation time) is set to 2 seconds as shown in FIG. 4A by the dial operation of the time setting dial provided in the timer 19, the key operation time in the RAM 16 is set. Stored in the repeat time register 16g.
[0032]
The change count register 16f in the RAM 16 is set to “1” in the initial process of the key input process in FIG.
That is, for example, when “A” is selected and pressed in the character input key in the key input unit 12, it is determined that the character input key is operated, and accompanying the continuous key operation from the time of the character key operation. The elapsed time is counted by the timer 19, and the key operation elapsed time measured by the timer 19 has passed the key operation time (size change timing) “2 seconds” stored in the repeat time register 16g in the RAM 16. It is determined whether or not (Step S1 → S2).
[0033]
Here, it is determined that the key operation elapsed time counted by the timer 19 from the time when the character input key “A” is operated does not exceed the key operation time “2 seconds” stored in the repeat time register 16g. If the character data “A” corresponding to the operation key has been input to the input buffer 16a in the RAM 16, it is determined whether or not the character data “A” has been input. Character code data corresponding to “A” is stored in the input buffer 16 a in the RAM 16 (steps S 2 → S 3 → S 4).
[0034]
In this case, in the attribute memory 16c in the RAM 16, the attribute information (character type / character size) associated with the character code data of the key input character data “A” is, for example, (Mincho / Are stored as full-width).
[0035]
Then, the Mincho full-size character font “A” read from the character generator 14 is written to the display register 16 b in the RAM 16, output to the display control unit 20, and displayed on the liquid crystal display unit 21 [ See FIG. 4B].
[0036]
When it is determined that the key operation elapsed time counted by the timer 19 of the character input key “A” has passed the key operation time “2 seconds” stored in the repeat time register 16 g, It is determined whether the changed character size set and stored in the size setting register 16d is set to “standard (full-width)” without change, or “enlarged” or “reduced” with change. (Steps S1->S2-> S5).
[0037]
If it is determined that the changed character size set and stored in the size setting register 16d in the RAM 16 is set to “standard (full-width)” without change, the character input key “A” As long as the key input operation of “” continues, the process of step S 1 → S 2 → S 3 or S 1 → S 2 → S 5 → S 3 is repeated, and the full-size input character data “A” remains displayed.
[0038]
On the other hand, the changed character size set and stored in the size setting register 16d in the RAM 16 is not “standard (full-width)” without change, but, for example, as shown in FIG. ) "Is determined to be set, whether or not the number of size changes set in the change count register 16f in the RAM 16 has reached the number of size change stages set and stored in the change stage number register 16e. Determination is made (steps S5 → S6).
[0039]
Here, the change count register 16f in the RAM 16 is initially set with the size change count set to “1” (a double-byte character input associated with the first key input is counted as one time). In the register 16e, for example, as shown in FIG. 4A, since the size change stage number is set to “3”, the change count “1” has not reached the change stage number “3”. When the determination is made, it is determined that the change is an enlargement change based on the change character size “enlarge (4 × 2)” stored in the size setting register 16d in the RAM 16, and the key input character data “A” 2 Stage expansion processing is performed (steps S6 → S7 → S8a to S10).
[0040]
That is, if it is determined in step S7 that it is an enlargement change, first, the change character size (setting magnification) “4 × 2” set and stored in the size setting register 16d in the RAM 16 is changed to the maximum magnification. The input character “A” currently stored as a full-width character in the input buffer 16a is enlarged and generated in double-width at the uniform enlargement magnification “double-angle” based on the size-changed step number “3” set and stored in the step-number register 16e. The character size of the attribute information stored in the attribute memory 16c corresponding to the input character "A" is changed from (full-width) to (double-width) (steps S8a and S9).
[0041]
Then, the full-width font pattern of the input character data “3” stored in the display buffer 16b in the RAM 16 is changed to a double-width font pattern, and is changed to the liquid crystal display unit 21 as shown in FIG. It is displayed (step S10).
[0042]
That is, when the character input key in the key input unit 12 is pressed and the duration of the pressing operation is 2 seconds, the input character data is enlarged and displayed in the second double size. .
[0043]
The size change count set in the change count register 16f in the RAM 16 is incremented by (+1) and set to “2” (step S11).
Thereafter, when it is determined that the same character input key “A” is continuously operated and the key operation time “2 seconds” stored in the repeat time register 16g is again passed, the RAM 16 It is determined that the changed character size set and stored in the size setting register 16d is not “standard (full-width)” without change, but “enlarged (quadrature)”, and the number of changes in the RAM 16 It is determined whether or not the number of times of size change set in the register 16f has reached the number of size change stages set and stored in the change stage number register 16e (steps S1->S2->S5-> S6).
[0044]
Here, the number of times of size change is incremented and set to “2” in the change count register 16f in the RAM 16, and the number of size change stages is set to “3” in the change stage number register 16e. It is determined that the change number “2” has not reached the change step number “3”, and the change can be enlarged based on the change character size “enlarge (4 × 2)” set and stored in the size setting register 16d in the RAM 16. If it is determined that there is, the third-stage enlargement process of the key input character data “A” is performed (steps S6 → S7 → S8a to S10).
[0045]
That is, if it is determined in step S7 that it is an enlargement change, first, the change character size (setting magnification) “4 × 2” set and stored in the size setting register 16d in the RAM 16 is changed to the maximum magnification. The input character “A” currently stored as a double-width character in the input buffer 16a is enlarged and generated to a quadruple size with a uniform magnification “double angle” based on the size change step number “3” stored in the step number register 16e. The character size of the attribute information stored in the attribute memory 16c corresponding to the input character "A" is changed from (double angle) to (4 double angle) (steps S8a and S9).
[0046]
Then, the double-width font pattern of the input character data “3” stored in the display buffer 16b in the RAM 16 is changed to a quadruple-width font pattern, and as shown in FIG. The change is displayed (step S10).
[0047]
In other words, when the character input key in the key input unit 12 is pressed and the duration of the pressing operation is 2 seconds, the input character data is displayed in a double-width double-size format. When the duration of the pressing operation is 4 seconds, the display is enlarged and displayed in the third stage, which is a quadruple angle.
[0048]
Then, the size change count set in the change count register 16f in the RAM 16 is incremented by (+1) and set to "3" (step S11).
Thereafter, when it is determined that the same character input key “A” is continuously operated and the key operation time “2 seconds” stored in the repeat time register 16g is again passed, the RAM 16 In the change count register 16f, the size change count is incremented and set to “3”, and in the change step count register 16e, the size change step count is set to “3”. Is determined to have reached the change stage number “3”, and the character size of the input character data “A” is maintained at the maximum magnification “4 ×” (steps S 1 → S 2 → S 5 → S 6 → S1).
[0049]
When the pressing operation of the character input key “A” is cancelled, the series of key input processes is ended (step S1 → END).
On the other hand, when the character size of the key input character data is reduced and changed, the key operation time set in the repeat time register 16g is obtained by continuously pressing the character input key in the same manner as in the case of the enlargement and change processing. Each time, the input buffer 16a is stored with a uniform reduction magnification based on the size change step number set and stored in the change step number register 16e having the change character size (set magnification) set and stored in the size setting register 16d as the maximum magnification. The input characters are reduced and generated step by step (step S7 → S8b), the character size data stored in the attribute memory 16c is reduced (step S9), and the font stored in the display buffer 16b. Pattern reduction / change processing (step S10) is sequentially executed.
[0050]
Therefore, according to the word processor configured as described above, when the character input key “A” of the key input unit 12 is pressed, the character code data corresponding to the input character data “A” is first stored in the input buffer 16 a in the RAM 16. The character size data stored in the corresponding attribute memory 16c is set to standard (full-width), and the full-width character font is written in the display buffer 16b and displayed on the liquid crystal display unit 21. When the character input key “A” is continuously pressed, the enlargement magnification “4 ×” set by the changeover switch A17 is changed to the maximum magnification every repeat time “2 seconds” set by the timer 19. With the change step number “3” set by the switch B18, the character size data of the input character data “A” is changed and displayed step by step from full-width to double-width to quadruple-width. During the changing process, the character data input process is interrupted one by one, and the input key can be changed to a desired one just by operating the character input key as it is without troublesome extra key operations for setting the size changing mode. You can easily change the font size.
[0051]
In the above-described embodiment, the character input key corresponding to the character to be input is continuously pressed, and the character size of the input character is sequentially changed and set according to the key operation time. The character string input by the character input key is converted into a desired kanji character by operating the “conversion” key, and the “execution” key for confirming the kanji character is continuously operated. It is good also as a structure by which the character size of a fixed Chinese character is changed and set in steps according to operation time.
[0052]
FIG. 5 is a diagram showing a change display example associated with the enlargement change process of the fixed kanji character size after the kanji conversion by the word processor.
That is, the character input key of the key input unit 12 is operated to input and display “Kashie”, and the “conversion” key is operated to change the character to “bare” and the “execution” key. To confirm the converted kanji “樫” and continue to operate the “execute” key, the key operation time set by the timer 19 is substantially the same as the key input process in FIG. For each time, the kanji character that has been determined to be converted into kanji is set with the number of change steps (in this case, 3 steps) set by the changeover switch B18, with the enlargement magnification (in this case, quadruple angle) set by the changeover switch A17 as the maximum magnification. The character size data of the data “樫” is changed and set step by step from full-width to double-width to quadruple-width.
[0053]
Further, in each of the above embodiments, the character size of the character data itself key-inputted by the character input key is changed by continuously operating the character input key (see FIG. 4), or “ In the above description, the character size of the kanji data determined by the “execute” key is changed by continuously operating the “execute” key (see FIG. 5). In a state where the character string data after processing is input and displayed, a certain control key (for example, “execute for cursor designation range confirmation instruction” is performed on character string data arbitrarily designated by the cursor operation. By continuing to operate the “key”), the character size may be changed stepwise as described above.
[0055]
【The invention's effect】
As described above, according to the input device that involved in the present invention was determined kanji by operating the conversion key enter the Do character data or by operating the character key by performing kanji conversion operation of the execution key In this case, the operation time of the execution key is counted, and the character size of the character data of the input kanji character determined according to the length of the time counting time, that is, the operation key operation time length from the time of kanji determination Since the data is changed, for example, when the desired kanji is converted to kana-kanji and confirmed with the execution key, the character size of the input confirmation character is gradually expanded or increased with the operation time by continuing to operate this execution key. It will be reduced.
[0057]
Therefore, it is possible to change the size of the input character data very easily without having to interrupt the input processing of the character data and newly set a character size change mode.
