Description

DETAILED DESCRIPTION OF THE INVENTION [Technical Field] The present invention relates to a character processing device that performs editing processing of characters such as characters.

[Prior art]

Conventionally, there is a character processing device that can automatically process characters that cannot be started at the beginning of a line or characters that cannot be at the end of a line. For example, a text input from a keyboard is displayed on a CRT screen, and various processes such as editing are performed on the CRT screen. At the stage when the input editing is finished, the prohibition processing has not yet been performed. When you instruct printout here, the prohibition process is automatically performed and output is performed for the first time.

However, in such an apparatus, the prohibition process is not performed unless the printout is actually executed, and the result of the process can be known only by looking at the printed paper. Therefore, it was impossible to modify the prohibition process that was automatically performed. On the other hand, it is also true that automatic prohibition processing has its limits and always requires modification.

[Objective] In view of the above points, an object of the present invention is to eliminate the above-mentioned drawbacks.

In view of the above points, it is an object of the present invention to provide a character processing device that can clearly notify the user of the location on the display, such as in which line the prohibition processing has been performed.

An object of the present invention is to provide a character processing device that is capable of editing characters after a prohibition process is performed while displaying a symbol indicating that the prohibition process has been performed.

An object of the present invention is to provide a character processing device that can prevent a displayed symbol related to prohibited processing from being displayed due to the influence of inserted character information even in insertion mode. It is about providing.

The purpose of the present invention is to make it possible to erase display symbols regardless of the input mode when the number of characters after prohibition processing increases due to character editing.
An object of the present invention is to provide a character processing device that can always output high-quality documents.

Other objects of the present invention will become clear from the following description of embodiments with reference to the drawings.

〔Example〕

Before specifically explaining the embodiments of the present invention,
First, terms used to describe this embodiment will be explained.

1 Equal allocation code It can be incorporated into this device by pressing the equal allocation key. When the character strings sandwiched between the equal division codes are printed, they are evenly allocated to the area defined by the equal division codes and output.

2 LOGO (Logotype) code This code can be imported into this device by pressing the LOGO key. When a character string between LOGO codes is printed, the horizontal character pitch is 0.

3. Line-inhibition processing Characters that are unnatural to be placed at the beginning of a line due to the characteristics of the Japanese language are sometimes placed at the beginning of a line during the character processing process. In such a case, by pressing the Kinsoku key, the character strings are automatically rearranged. Non-first-line characters include the following: . ,),． ,,,〓,'',],
},
A, I, U, E, O, Ya, Yu, Yo, Tsu, Ka,
ke, a, i, u, e, o, ya, yu, yo, tsu 4 Line-end prohibition processing Characters that are unnatural to be placed at the end of a line due to the characteristics of Japanese are It may be placed at the end of. In such a case, by pressing the prohibited key, the character strings are automatically rearranged. Characters that cannot end a line include the following:

(, ", 〓, [, {, ¥, $$] Next, an outline of an embodiment according to the present invention will be described. In addition to character information, various function information is input from the keyboard. The character information input from the keyboard is displayed. It is displayed on the device, and editing processing such as insertion, overwriting, and deletion can be performed.
Further, the desired input position on the display device can be freely selected by moving the cursor using the cursor keys.
When attempting to print a LOGO, encode a partial pattern of the LOGO and sandwich that code string between LOGO codes. The LOGO code can be input by inputting the LOGO key, and the partial pattern code can be input by providing a key corresponding to the code on the KB.

When printing, the character pitch is 0, and as a result, the partial patterns are composited.
A LOGO pattern is output.

When attempting to perform equal division printing, the area to be equally divided is specified by an equal division code, and a character string is input between the areas. Here, it is assumed that the space codes that precede and follow the character string do not constitute a character string to be divided evenly, even if they are sandwiched between equal division codes, for example.

The equal division code can be input by pressing the equal division key.

In order to automatically perform the prohibition process on the character string input in this manner, the prohibition key is pressed. When the prohibition key is pressed, all prohibition characters existing at the end or beginning of a line are removed from that position, as shown in FIG. 9b. As a result, a prohibition code (indicated by a prohibition mark) is inserted as shown in FIG. 9b.

Once an attempt is made to insert or delete a character string that is in this form, special processing is performed for the prohibited code. That is, in the case of insertion, the prohibited code is eaten by the character string that exists before it, as shown in FIG. 7b. In deletion, the number of prohibited codes increases as shown in FIG. 8b. By performing such processing, it is possible to minimize the possibility that a character string that has been subjected to prohibition processing once again becomes arranged in violation of prohibition due to editing processing.

The CRT string created in this way is
By pressing the PRINT key, it is printed out on printing paper.

When printing, equal distribution is specified, and character strings specified as LOGO are printed in the specified layout. When printing a line in which a prohibition mark exists, the prohibition mark is removed and the remaining character strings are printed evenly distributed within the left and right margins.

7.2 If a Kinsoku code exists after the cursor position, proceed to step 7.3; otherwise proceed to step 7.4.

7.3 The character string after the cursor position must be advanced because characters are inserted, but the character string that is advanced must be after the cursor and up to the Kinsoku code closest to the cursor. Therefore, the prohibition code will disappear. Proceed to step 7.5.

7.4 Send all strings after the cursor one by one. Discard the last character.

7.5 Write input DATA to the cursor location.

7.6 Execute cursor key input processing (6) to advance the cursor one step.

9.1, 9.10, 9.11 Repeat steps 9.2 to 9.10 in order from the line where the cursor is located to the last line.

9.2 Check whether there is a non-end-of-line character at the end of a line. If it exists, proceed to step 9.3 to execute line-end prohibition processing.

9.3 Find out how many consecutive characters that cannot end a line,
Let that value be NUM.

9.4 If NUM is greater than 4, set NUM = 3.
That is, it is assumed that the prohibition process is executed for up to three characters.

9.5 9 - NUM in the digit position represented by the value of NUM
Insert the number of Kinsoku codes represented by the value of . (The insertion process is exactly the same as the insertion process shown in FIG. 7a.) Here, 9 is the value of the number of characters in one line+1. Proceed to step 9.10.

9.6 Check if next line exists. if,
If it exists, there is a possibility that first-of-line processing will be performed. If it does not exist, there is no need to perform no-first-of-line processing. Step 9.10
Proceed to.

9.7 Check whether a non-first line character exists on the next line. If it exists, proceed to step 9.8 to perform the no-first-of-line processing. If it does not exist, proceed to 9.10.

9.8 Check whether there are no-start characters at the end of the current line and set the number to NUM.

9.9 Increment NUM. Proceed to step 9.4. (NUM is the number of characters that should be subjected to the prohibition process.) The middle diagram in Figure 9b is a diagram in which the end-of-line prohibition process is applied to the first line, and the bottom figure is the figure in which the line-inhibition process is applied to the second line. It is a drawing.

[Print key input processing]

If the print key is operated, the first
The process shown in Figure 0 is performed.

10.1 Pitch determination process 10.2 Print processing The above steps will be further explained.

10.1 Determine the horizontal pitch of information to be printed. (Pitch determination process) 10.2 DATA according to the determined pitch
Prints the information stored in BUFFER. (Print Processing) [Pitch Determination Processing] Step 10.1 shown in FIG. 10 will be further explained using FIG. 11a. Each step performs the following processing.

10.1.1 Register LN (line number) = 1 10.1.2 Standard pitch determination process 10.1.3 Equal split pitch determination process 10.1.4 LOGO Pitch determination process 10.1.5 Inhibited Pitch Determination Process 10.1.6 Register LN Increment 10.1.7 Have all rows been processed? Each of the above steps will be further explained.

10.1.1, 10.1.6, 10.1.7 Determine the horizontal pitch for each line from the first line to the last line.

10.1.2 Standard Pitch Determination Process 10.1.3 Equal Pitch Determination Process 10.1.4 LOGO Pitch Determination Process 10.1.5 Inhibited Pitch Determination Process [Example of Pitch Determination Process] Figure 11b shows an example of the pitch determination process. 10.1.0
Let be the DATA stored in the data buffer. The figure shown in 10.1.2 shows the values in the PPB (print pitch buffer) as a result of standard pitch determination processing. Each value in PPB is DATA
Indicates the horizontal absolute address at which each character code in BUFFER will be printed. In this example, the character pattern consists of a 9x7 dot matrix, and the character pattern is a standard horizontal character.
Printing is performed with a pitch of 10 dots. Therefore, in the PPB, 10.1.2 in Figure 11b
It will take the value shown by . The diagram shown in 10.1.3 shows the effect of equal division on the second row.
This has been corrected for PPB. This corrects the position where each character of KLM on the second line should be printed. Here, the character code expressed as 99 in the PPB means that printing is not required. That is, there is no need to print the equal division mark.

Since the character K is to be printed out at the starting position of the evenly divided area, the print position of the character (the horizontal absolute address of the position to be printed expressed in dots) is 20.

Since the letter M will be printed out at the end of the equally divided area, the printing position of the letter will be
It will be 70.

Since the letter L will be printed at a position intermediate between the letters K and M, the printing position will be 45.

The figure shown in 10.1.4 shows the PPB correction for the third row due to the LOGO printing effect.
The position where the letter R should be printed remains unchanged. Since the letter S must be printed adjacent to the letter R, the printing position is changed to 47.

The figure shown in 10.1.5 shows the correction in the PPB due to the forbidden printing effect on the 4th line.
The printing position of the character string character U remains unchanged, and the printing position of the character Z becomes 70. The string of characters sandwiched between the letters U and Z will be evenly distributed between them.

[Standard pitch determination process]

Step 10.1.2 of the standard pitch determination process shown in FIG. 11a will be further explained with reference to FIG.

10.1.2.1 A _LN,CN = 10 x (CN-1) (CN = 1, 2, 3..., 8) Using the above steps, determine the horizontal direction to be printed for each character based on the standard character pitch (10 dots). Calculate the address in dots and write it in the PPB.

That is, ALN, _CN = 10 x (CN - 1) _CN = 1, 2, 3..., 8.

[Evenly divided pitch determination process]

(10.1.3.4) 10.1.3.6 to 10.1.3.9 Find the end position of the area to be equally divided, that is, the position of the equal division code that appears corresponding to the position of CNS, and set it to CNE. Return if the equal division code is not found (10.1.3.7) 10.1.3.10 Find the first digit SC, last digit EC, and number of characters NUM of the character string to be divided evenly. Equal division character count determination process 10.1.3.11 Equal division processing to correct the value in PPB Execute the above process from the beginning to the end of one line.

10.1.3.10.1 to 10.1.3.10.5 Find the beginning of the character string to be evenly divided within the area to be equally divided, that is, the area defined by CNS and CNE (10.1.3.10.2) and set to SC. (10.1.3.10.5) The beginning of the string to be divided evenly shall be defined by the position of the first code other than the space code. If the character string does not exist, proceed to step 10.1.3.10.11.

10.1.3.10.6 to 10.1.3.10.10 Find the end of the string to be equally divided within the area to be equally divided (10.1.3.10.7) and set it to EC.
(10.1.3.10.10) The end of the character string to be evenly divided is defined by the position of the first code other than the space code that appears upwards from the end of the evenly divided area. If the string does not exist, step
Proceed to 10.1.3.10.11. Other time steps
Proceed to 10.1.3.10.12.

10.1.3.10.11 This step comes when there is nothing other than a space code in the equally divided area. Although it does not originally have the meaning of equal division, let us temporarily set SC=EC=CNS.

10.1.3.10.12 Calculate the number NUM of character strings to be equally divided in the evenly divided area.

NUM=EC−SC+1 [Equal division processing] The equal division processing (10.1.3.1) shown in FIG. 13 will be further explained using FIG. 15.

10.1.3.11.1 If the number of characters subject to equal division is 1, proceed to 10.1.3.11.7, otherwise proceed to 10.1.3.11.2.

10.1.3.11.2 Divide the size of the equal division area (A _LN,CNE −A _LN,CNS ) by the number of characters subject to equal division minus 1 (NUM−1), and calculate the quotient by AP.
Let the remainder be RP.

10.1.3.11.3 If RP≠0, proceed to step 10.1.3.11.4.

If RP=0, proceed to step 10.1.3.11.6.

10.1.3.11.4 The first RP character in the character string to be equally divided shall have a character pitch of AP+1.

That is, A _LN,CN = A _LN,CNS + (AP+1) x (CN-SC) (CN=SC, SC+1,..., SC+RP) 10.1.3.11.5 Let AP be the character pitch of the remaining character string.

That is, A _LN,CN = A _LN,SC+RP +AP×(CN-SC-RP) (CN=SC+RP+1, SC+RP+2,..., EC) Proceed to step 10.1.3.11.9.

10.1.3.11.6 All character pitches of characters subject to equal division are AP.

That is, A _LN,CN = A _LN,CNS + AP x (CN - SC) (CN = SC, SC + 1,..., EC) Proceed to step 10.1.3.11.9.

10.1.3.11.7 When the number of characters to be evenly divided (NUM) is 1, the character shall be printed in the center of the evenly divided area. Therefore, to find the center position, perform the following calculation.

A _LN,CNE +A _LN,CNS divided by 2, quotient AP remainder RP
shall be.

10.1.3.11.8 Let AP be the printing position of the character.

That is, A _LN,CN = AP (CN = SC) 10.1.3.11.9 The steps from 10.1.3.11.9 to 10.1.3.11.12 are print positions other than the character strings to be equally divided that exist in the evenly divided area. Set all to 99. First, it is checked whether or not there is a character that is not subject to equal division at the beginning of the equal division area.

That is, if CNS=SC, it does not exist, and the process proceeds to step 10.1.3.11.11.

If CNS≠SC, it exists, and proceed to step 10.1.3.11.10.

10.1.3.11.10 Set the print position of all non-equal distribution characters at the beginning of the equal distribution area to 99.

That is, A _LN,CN =99 (CN=CNS,...,SC-1) 10.1.3.11.11 Check whether there is a character that is not subject to equal division at the end of the equal division area.

That is, if CNE=EC, it does not exist and returns. If CNE≠EC, it exists, so proceed to step 10.1.3.11.12.

10.1.3.11.12 Set the print position of all non-equal distribution characters at the end of the equal distribution area to 99.

That is, A _LN,CN =99 (CN=EC+1, EC+2, . . . , CNE) At this step, the equal division process ends.

[LOGO Pitch determination process]

Furthermore, the LOGO pitch determination process shown in Figure 16
10.1.4 will be explained based on Figure 16.

10.1.4.1 CN=1 10.1.4.2 C Is _LN,CN a LOGO code? 10.1.4.3 CN increment 10.1.4.4 CN>9? 10.1.4.5 CNS=CN 10.1.4.6 CN increment 10.1.4.7 CN>9? 10.1.4.8 Are C _LN,CN LOGO codes? 10.1.4.9 CNE=CN 10.1.4.10 LOGO Processing Each of the above steps will be further explained.

10.1.4.1 to 10.1.4.5 Search for the beginning of the LOGO area from the beginning of the LN line. If it does not exist until the end, return (10.1.4.4). If the beginning of the LOGO area is found (10.1.4.2), set the first digit number in the CNS (10.1.4.5).

10.1.4.6 to 10.1.4.9 Search for the ending digit number of the LOGO area. If not found by the end of the line (10.1.4.7), return. If the end digit of the LOGO area is found (10.1.4.8), set the end digit number to CNE. (10.1.4.9) 10.1.4.10 Determine the printing position of the LOGO target character string.
(LOGO Processing) Next, proceed to step 10.1.4.3 to search for another LOGO area in the row.

[LOGO processing]

The above-mentioned LOGO processing 10.1.4.10 (FIG. 16) will be further explained using FIG. 17. Such processing steps consist of the following steps.

10.1.4.10.1 A _LN,CN = A _LN,CNS +1+7×(CN−
CNS-1) 10.1.4.10.2 CN=CNS+1, CNS+2,...
CNE-1 10.1.4.10.3 A _LN,CNS = 99 10.1.4.10.4 A _LN,CNE = 99 The steps described above do the following: LOGO processing 10.1.4.10 (Figure 17) 10.1.4.10.1 LOGO target character strings shall be all characters sandwiched between LOGO codes.

The printing position of the first character of the LOGO target string does not change. Characters following the first character are printed in close contact with the first character. That is, the characters after the first character are printed at a character pitch of 7 (character width).

That is, A _LN,CN = A _LN,CNS +1+7×(CN−CNS−
1) (CN=CNS+1, CNS+2,..., CNE-1) 10.1.4.10.2, 10.1.4.10.2 Set the printing position of the first and last LOGO codes that define the LOGO area to 99.

[Kinoku pitch determination process]

Inhibited pitch determination process shown in Figure 11a (10.1.5)
will be explained using FIG.

10.1.5.1 Is C _LN,8 a forbidden code? 10.1.5.2 CN=6 10.1.5.3 C Are _{LN and CN} prohibited codes? 10.1.5.4 CN Decrement 10.1.5.5 CN<1 10.1.5.6 EC=CN 10.1.5.7 CN=1, SC=1 10.1.5.8 C Are _LN,CN equal division codes or LOGO codes? 10.1.5.9 SC=CN+1 10.1.5.10 CN increment 10.1.5.11 CN>9? 10.1.5.12 SC＞EC? 10.1.5.13 CNS = SC 10.1.5.14 CNE = 8 10.1.5.15 NUM = EC - SC + 1 10.1.5.16 Equal division processing (10.1.3.11) The above processing will be specifically explained.

10.1.5.1 Check whether a Kinsoku code exists at the end of a line.
Returns if it does not exist. If it exists, proceed to step 10.1.5.2.

10.1.5.2 - 10.1.5.6 If a prohibited code exists at the end of a line, the position excluding the prohibited code (there may be multiple consecutive codes) is the end of the character string to be equally divided. Therefore, find the position where a character other than the forbidden code that appears starting from the end of the line exists (10.1.5.3) and use that digit number as the value of EC. (10.1.5.6) 10.1.5.7 to 10.1.5.11 The beginning of the character string subject to equal division is generally the beginning of the line, but if there is an equal division code or
If a LOGO code exists, the position is to the right of that position. Therefore, in order to find the beginning of the character string to be equally divided from the beginning of the line, a code check is performed for each character (10.1.5.8). The first digit number SC of the character string to be equally divided is initially set to 1, but if it becomes necessary to change it (10.1.5.8), the SC value is updated (10.1.5.9). In this way, SC is determined.

10.1.5.12 Compare SC and EC, and if SC≦EC, equal division processing can be executed, so proceed to step 10.1.5.13.
Returns when SC>EC.

10.1.5.13 Set the leading digit number of the evenly divided area.

That is, CNS=SC 10.1.5.14 Set the last digit of the evenly divided area.

That is, CNE=8 10.1.5.15 Calculate the number of characters in the string to be divided evenly.

That is, NUM=EC−SC+1 10.1.5.16 Determines the printing position of each character.

(Equal division process 10.1.3.11) The prohibited pitch determination process is performed using the steps described above.

10.2.2, 10.2.6, 10.2.7 Print each character from the first digit to the last digit.

10.2.3 When the print position is 99, the corresponding character will not be printed. Therefore proceed to step 10.2.5. Otherwise proceed to step 10.2.3.

10.2.4 Feed the print head to the position to be printed.
(Gives head feed instructions to PRTC) 10.2.5 Prints the corresponding characters. Printing is performed by referring to the CG for a character pattern corresponding to the character code (C _{CN, CN} ) of the relevant character, and outputting the pattern to the PRTC. Proceed to step 10.2.6.
