Description

[Detailed Description of the Invention] [Technical Field] The present invention uses an input device such as a keyboard or a touch pen'-9 while viewing the output display screen of an output display device such as a CRT (cathode ray/Fi') or a liquid crystal display. A character processing device that performs character processing such as creating, editing, or composing a sentence-7;
．． Regarding ゛, l.

[Prior Art] Conventionally, in this type of character processing device, for example, a word processor, when a character group such as a phrase or a compound word that has already been used is reused during document creation and composition, the processing time is -1 shallow. Rather than re-entering each character one by one, it is much more convenient to input using the copy (transcription) function of character 11'1, and in order to reduce input errors, it is recommended to use a copy function (III) or a variety of devices. has been done.

However, in these conventional devices, for example, character 11 of the phrase N to be copied by a range specification key is
When specifying '4, there was no means to clearly inform the input operator whether the range from the characters to the characters was specified. As a result, there was a drawback in that human errors in the input operation for specifying the area were often not noticed.

Furthermore, with conventional devices, it is not possible to copy two or more non-contiguous character groups by concatenating them.

Furthermore, with the conventional apparatus, it is not possible to add or delete characters, or to add or delete characters, such as jT, '+I, etc., to the characters IY (-J-cut 4:Ml-four-finger-toed-phrase-na) before transcription.

[0 勺] An object of the present invention is to eliminate the above-mentioned drawbacks, and to output character strings such as phrases and compound words specified in a range to the input i1. j, work J1 to 1
1- to make it easier to confirm 11α of the string of pure fingers and toes.
Then, we developed a character processing device that improved the efficiency of human operation, and even improved input accuracy.
It's about what I do.

Another object of the present invention is - world: l'+ij, four fingers)
An object of the present invention is to provide a character processing device that allows editing such as addition and deletion to a character string that has been displayed.

Furthermore, another object of the present invention is to combine character strings into one character string, such as a phrase in two places, a phrase, and a compound ah, to specify a range. The purpose of this invention is to provide a processing device.

All operations in the device of the present invention are performed using the keyboard KB.
This is done by operating the J- character key or function key. Further, the LMM of the index to be filled with B 31J (A) is displayed with a left margin code and a > mark on the front claw device CRT, which increases or decreases the leftmost end that can be input from the key 1;'KB. RMM is a margin code, and it is displayed with a mark of 1\"J, and displays the rightmost edge that can be entered from Keyho F'KB. Furthermore, CM is for the main text. MCM is a cursor for monitoring, and MLM displayed with a tree mark indicates the beginning of a line with a monitor line, and MCM is a cursor for monitoring. There is no monitor cursor MGM, and only the scenes related to range specification are displayed.

When the power is turned on, only a cursor CM is displayed on the display screen 1- of the display device CRT at the top position on the left side of the child, as shown in FIG. Next keyho+: Character processing action f [by pressing the key above xB. In other words, the characters inputted into the keyboard by 6) are sized and placed at the position where the cursor CM is displayed on the large and small surface 1- of the display device CRT, but the cursor CMC7) size and small position are To input characters, etc. from the keyboard KB: +F: ;M1ll-. Incidentally, since it can be easily realized using the publicly known technology, the detailed explanation of step 7 will be omitted.

Next, to specify the transfer or movement range, an example of what is displayed on the monitor line of f will be explained. First, 4 < l, i pi i (for example, the position of character A) at the beginning of the character group for which you want to specify the range. After moving the cursor r2H as shown in Fig. 3 (A) by pressing the cursor movement key GK, press the range specification start button -H8S'K.
A” letter or range finger>j! At the same time, the characters rA-J are displayed on the monitor line. Next, if you move the cursor (J to B and C sequentially, the character rAJ will be followed by rE, J, rCJ, or the same 1 will be registered in the range specification.
1(r), "ABC-" is displayed on the monitor line as shown in Figure 3 (B).Next, when the range specification path key H8EK is pressed, the range specification display disappears from the monitor line, and the normal Returns to the display state of the monitor line during operation.

Next, as shown in Fig. 4 (A), after moving the cursor under the large, small, and medium text letters ``J'' and pressing the 1lili box specification start key H9K, ``I'' is displayed in the same manner as described above.
'' is newly registered in the range Hanfa HBUF, and the already registered T A B'CJ is deleted and displayed on the monitor line as rI-''. Range specification registration continues until the specified path key H:;EK is pressed.

However, when the cursor CM came to 1 of rIJ, without pressing the range specification start key) ISK, Fl;? If you press the start key 7HKSK, the range specification buffer HBtlF will contain r A 13 C as shown in Figure 4 (fl).
An "I" or a character for specifying a range is written at the end of J, and rABCI J is displayed on the monitor line. After that, as the cursor CM moves until the range join end key (IKEK) is pressed, 1, this sieve, enclosure, 51, etc. The J processing and the display processing are repeated, and if the character "l(" is registered as a range specification by the range joining processing as shown in FIG. 4(C), [ABCIJ

When KEK is pressed, the rABCIJK J face 1\ disappears from the pl+i side L: of the monitor line and the screen returns to the normal operation screen display.

Next, if you press the monitor key MNK while the cursor C is at the character rRJ in the text being displayed as shown in Figure 5, the range has already been registered on the monitor line. r A BCIJK J is displayed, and when you press MNK again, the display of rABCIJK J disappears from the monitor line, and the display of moko during normal operation becomes gray, and you can insert and delete character groups specified in the range. 1JIIi East processing will be explained. The σf function is available during this process range specification process, during range combination process, and during range monitoring obtained by pressing the monitor key MNK. We will explain the case where you press M14K and press e on both sides of the a + "U" monitor.

First, when the range monitor is displayed on the monitor line, the monitor cursor MGM can be moved left and right by pressing the monitor cursor key MCK. Now, when the monitor cursor MCM is moved from the display state shown in Fig. 5 to the position shown in Fig. 6 (A) by using the monitor cursor key MCK to move the monitor cursor MCM to the position shown in Fig. 6 (A), press the delete key SJ.
When you press K, the character code of the character "ENG" on the monitor cursor is deleted from the range specification buffer HBUF, and then the character code of ``°C rJ'', rK'' is deleted from the range specification buffer I (BUF). are carried forward sequentially (i.e. H
(means that BUF (n+1) is stored in HBUF (n)), and the display screen is similarly iJ<
It becomes like this.

Also, instead of pressing the delete key SJK in the state shown in FIG.
When you enter the character key, the range specification buffer) IBtlF
At the same time that the character code "x" is inserted in
The character codes ``, rJ'', rK, and + are sequentially lowered, and the monitor screen becomes as shown in the 71st KI (A). However, if the character key "z" is pressed without pressing the insert key SNK when the size is 117i in FIG. The character code rZJ is rewritten at the location and the 1 display screen is also output as shown in FIG. 7(B).

Flowchart 1 in FIGS. 7 and 8 shows an example of the control operation of the two systems of the present invention in further detail. To explain this, first, after turning on the power, the keyboard K
If there is key human power from B, the type of key human power is determined in step S1, and the process branches to the following steps depending on the determined type of key human power.

At this time, if the key input is the range specification start key H3SK, the process moves from step Sl to 82, where the general-purpose parameter register i is set to ``1'', the general-purpose parameter register J is set to ``61'', and the monitor cursor register is set to ``61''. Initialize by setting ``61'' in NCR and ``1'' in range specification flag H9F, clear all areas MBtlF(,1) to MBUF(10) of monitor buffer MBUF, and clear the area of refresh memory RM. RM(81)~R
The contents of M(70) are converted to its MBUF(1) to MBUF(1

Next, the process proceeds to step S3, where (il'l
A blank coat is arranged (stored) in area R from (61) to RM (70), and a monitor kernel MCM is displayed on the display surface of display device B and cRT. Next, the process moves to step S4, and the character code of the address position of the refresh memory RM, which is small by the current cursor register CCR, is transferred from the register i of the range specification buffer HBLIF to the small area HBUF(
i) and in register J or small area RM(j) of refresh memory RM, and store the values of register i and register j and (+) of monitor cursor register NCR.
Incrino/1· is increased by +1 for each Tj (see FIG. 3(A)). As a result, range specification start key 1 (SS
The process of arranging K's key power ends -r.

On the other hand, if the key in step St is the cursor movement key GK, the process moves from step S5 to step S6, and the contents of the current cursor L and register CCR are moved to the position where the j key GK is moved to 11 "1". The address (if is changed. Then, in the next step S7, it is determined whether the range designation flag H3F or °1" or the range combination flag) IKF is °1", and if -
If it is a 1"J fixed judgment, the process of step S4 described above is performed, and if it is an assessment judgment, the process for the manual key of this key GK is finished. For example, when the range specification start key H65H is pressed, bl, !, When the cursor movement key CK is pressed down, the flag H8F is
is set to "l", so step S7 is 1"?
The determination is made and the process of step S4 is performed (see FIG. 3 (13)).

Also, if the key power is the range specified road key H3EX,
Shifting from step S1 to step S8, the range specification flag H8F is turned off (°0''''), and the contents of areas MBUF(1) to MBUF(10) of monitor buffer MBUF are refreshed into a predetermined area RM of refresh memory RM. (61

If any of the keys H8EK, HKSK, HKEK, and MNK is not manually powered, the process proceeds to step S5 in which it is determined whether the key is manually powered by the cursor movement key CK. At this time, if the cursor movement key GK is not input,
A negative determination is made in step S5, and the process moves to step S15, where it is determined whether any of the range designation flag H5F, range combination flag HKF, and monitor flag MNF is set to 0. In other words, it is determined whether either range specification or range combination monitor processing is in progress. If the determination is 1 in step 515, proceed to other processing, that is, normal sentence, 1: creation processing, and proceed to 4''
When the judgment is positive, the following 7 temps S l 7 to 820 are selected in step 316 depending on the type of key manually operated.

In this way, according to the present example, the character processing device 11, which specifies the characters and graphic information displayed on the y Akaneri table knife r1j, by specifying the range, places the characters specified by the range specification at the location 'A'. !
It can be displayed on the second monitor line. Also,
I want to specify a range of discontinuous characters Jlf 111! Easy to use
This can be easily achieved by performing simple key operations.

Furthermore, characters can be inserted, deleted, or changed on the monitor line 1- as necessary.

In addition, in this example, if there are 91 range specifications, the range designation l
i: 'If you specify the starting position and then move the cursor 11", the character code is registered in the range according to the trajectory of the cursor.The present invention is not limited to this. First, for example, find the cursor position of 11!j, which specified the start of range specification; In other words, when specifying the start of range specification or the start of range combination, the cursor position is set to 2[(-/(ji) and then the cursor is moved appropriately. °δ
While constantly calculating , the group of characters between the cursor of that person is displayed on the monitor line as many as 11 characters are possible.By changing the program of the read-only memory ROM, we start specifying the range. End, 1a! It is also possible to specify a range using the cursor specified at the beginning and end of the enclosing bond. It goes without saying that the same effect can also be obtained by inputting a predetermined command instead of using keys such as range designation keys.

[Effects] As explained above, according to the present invention, a group of characters specified in a range is outputted in a predetermined table, J< plane, so that the character string within the specified range can be accurately and IP This makes it easy to input, thereby preventing input errors, and making +1 operations the same as 1-. Furthermore, according to the present invention, −=−1J15・1・
You can easily edit the specified character string by adding another character tag or deleting characters. In general, according to the present invention, there is an advantage that character strings located at fixed positions can be combined to specify a range as one character string.
