Description

DETAILED DESCRIPTION OF THE INVENTION Field 1 The present invention relates to a ruled line block processing device that handles documents with ruled lines.

[Prior Art] Conventionally, in a device that creates a document using a line display, one document is written in a block format. Or,
! When creating a document with 14 lines, there was the following method.

(A) Decide the number of characters in one line in advance, form blocks on the left and right within the line, and input the character string in each line while taking into account the upper and lower blocks. When dividing blocks with ruled lines, input the ruled line mark itself directly between each character or use an angline.

(B) For a serial character string document arranged in a row, a block framework is created separately and each block is managed separately.

In the case of method (A) mentioned above, editing processing (insertion,
If the block format is changed (deletion, etc.), the format of the block collapses, and the editing must be done again taking the block format into consideration. On the other hand, in the case of method (B), if editing processing (insertion, deletion, etc.) is performed on the document, there will be a mismatch in the size of the document and the block, and in some cases, problems such as blocks protruding may occur. The drawback was that the blocks had to be set up again.

[Purpose] The present invention compensates for the above-mentioned drawbacks, and converts a document consisting of one serial character string into a block format by simultaneously providing delimiter marks for dividing the character string and block digit position information. As a result, even if you edit the document, the shape of the blocks will not be distorted, and even if you draw borders between blocks, the borders will not shift, so the shapes of the document and blocks should always be consistent. An object of the present invention is to provide a ruled line block processing device that can handle ruled line blocks.

[Concept of the present invention] The concept of the present invention is shown in FIG. Column position information is stored simultaneously with characters by the specifying means. This l-line memory is assembled and converted into a ruled line block document using a ruled line block creation means.

[Example] An example of the operation according to the embodiment of the present invention is shown below. As shown in FIG. 5(a), first a character string is serially input in one column, and then as shown in FIG. 5(b). Set the vertical separator digits of the street block as [1, 4, 9] at the beginning of the character string using the keyboard, and insert a mark indicating the character separator into the character string.

When the ruled line block key is pressed after creating such a character string, an M line block is created as shown in FIG. 5(c). "Aiueo" up to the first "mark" is plain text, and from the first character to the place where two "marks" are consecutive, that is, "War ABC/abc Kenaiu φ12..." becomes a block format document. Hereafter, ``tachitsuteto'' will be translated as plain text again.・Marks also have the meaning of dividing blocks with ruled lines. In this case, the digit where the vertical ruled line is drawn is the number at the beginning of the sentence [
1, 4, 9], and the horizontal ruled line position is automatically determined according to the length of the row of each block.

If the omit ruled line key is pressed before pressing the ruled line block key, a block format is created as shown in FIG. 5(d), but the document becomes a block format document in which all ruled lines are replaced with spaces. Also, if you press the fill-rules key before pressing the ruled-block □ key, the horizontal ruled lines inside the block will be omitted while leaving the outer ruled lines and vertical ruled lines, as shown in Figure 5 (el). It becomes a block format document with one line stuck.

The present invention will be described in detail below with reference to the drawings. 2 is a diagram showing an example of the configuration of the character processing device of the present invention. C

This key also includes a DK for inputting a mark φ for block division, which will be described later. The cursor left movement key and right movement key are keys for moving the cursor, which indicates the character position on the display, left and right. The ruled line block key KBK is a key for creating a ruled line block from a serial character string.

The rule filling key KCK is a key for omitting horizontal ruled lines inside a block, and the ruled line omission key KAK is a key for omitting adjacent ruled lines and replacing them with spaces when the block is formatted. The print key PK is a key for printing the contents of the block memory BRM.

FIG. 4 shows the document memory BSM in the RAM in FIG.
FIG. 4 is a detailed explanatory diagram of a block memory BRM, a vertical ruled line table TKT, and a small block range table SHT.

The document memory BSM is a serial memory in which character information is stored, and is configured in address order from the beginning.
M (1), BSM (2)---Generally BSM (i
). The block memory BRM has a 9x9 matrix structure, and addresses are assigned in order from the first digit of the first row, BRM (1, 1), BRM (1, 2
)---Generally expressed as BRM (x, y). The vertical ruled line table TXT is a table for storing the vertical ruled line digit positions set in a document, and addresses are assigned in order from the first row, TKT (1), TKT (1)---generally TKT (p). express. Small block range table S
IT is a memory that has pairs of start and end digits indicating to which range of the block memory the character information of each small block is to be transferred, starting from the beginning with SHT (1, 1), S
HT (1, 2), 5HT (2, 1) --- generally SH
Expressed as T (m, 1) and SIT (m, 2).

Under the above configuration, the operation of the embodiment of the present invention is illustrated in FIGS. 6 to 1.
This will be explained with reference to the flowchart in FIG. O and examples of memory contents in FIGS. 11 and 12.

When this device is powered on, it first proceeds to step sl in FIG. 6. In step s1, the document memory BSM in the RAM,
Clear the space in block memory BRM, vertical ruled line table TKT, ruled line flag KF, ruled line filling flag KTF,
The ruled line start flag KSF is cleared to O, the cursor is set to the beginning of the document memory BSM, and the cursor position memory CRLM is set to the initial state.

Thereafter, the process advances to step S2, and the state of waiting for manual input of keys from the keyboard as shown in FIG. 3 is maintained.

If any key is input, the process proceeds to step S3, where the input key is determined, and the process proceeds to any one of steps 54 to S9.

Step S4 performs processing when a character key is operated.When the 0 character key is operated, the cursor position memory CRLM
The character code is stored in the document memory BSM corresponding to the character code.

Thereafter, the cursor advances by one, and at the same time, the contents of the cursor position memory CRLM also advance by 17112 minutes.

In step S5, processing is performed when the cursor right movement key or the cursor left movement key is operated, that is, if the cursor left movement key is operated, the cursor position memory CRLM is
When the cursor right movement key is operated, the contents of the cursor position memory CR are decremented by one address.
Processing is performed to add the contents of LM for one address.

In step S6, a process is performed when the line filling key is operated. When the line filling key is operated, the process of setting the line filling flag KTF in the RAM to l if it is 0 and to O if it is l is performed. .

In step S7, processing is performed when the ruled line omission key is operated. When the ff'F line omission key is operated, the 11th line flag KF in the RAM is set to l when it is O, and to 0 when it is 1. Process.

In step s8, a ruled line block is assembled from the contents of the document memory BSM shown in FIG. 4, and the result is stored in the block memory BRM.In step S9, the contents of the block memory BRM are printed by the printer P using the print key PK. .

FIG. 7 shows a detailed explanation of the contents of step s8. This will be explained below with reference to FIG. First step s8.
1 sets the pointer l in the document memory BSM to 1.

Next, proceed to step 38.2, find the digit position of the vertical ruled line in each block from the digit position information that separates the blocks at the beginning of the document memory BSM, and create the vertical ruled line table TXT. Represented by numbers between marks. According to the example in Figure 11 (1), 1,4
．． 9 is digit position information. As a result, a vertical ruled line table TXT is created as shown in FIG. 11(2).

Next, the process proceeds to step 88.3, and the number of small blocks arranged in the horizontal direction is determined and set to the small block number SS in the RAM. 1st
In the example shown in Figure 1, there are three vertical ruled line digit positions, 1, 4.9, so the number of small blocks that can fit between them is two.

Further, the process proceeds to step 88.4, and the digit range within which each small block fits is determined from the vertical ruled line table TKT. Figure 11 (2
), there are three vertical ruled line digit positions, 1 and 4.9, so the two small blocks are 2 to 3.5, respectively.
This will fit within 8 digits. The example shown in FIG. 1 (3) is a table of this. Furthermore, pointer m of this small block range table SHT is set to 1,
On the other hand, the pointer i of the document memory BSM is set after 1 indicating the end of the digit position information.

In step 88.5, characters from the character indicated by pointer i to the first delimiter mark in the document memory BSM are set in the block memory BRM.

The details will be explained using the flowchart of FIG.

First, in step s8.5.1, the pointers X t Y of the block memory BRM are set to l respectively.
= 5.2, the content of the document memory BSM is determined and branched. Pointer I is incremented by 1 before branching to 0. If the result of 0 character determination is a delimiter mark, this routine exits. On the other hand, if it is a normal character, the process branches to step s8.5.3 and the contents of the document memory BSM are transferred to the block memory BRM.

Furthermore, 1 is added to the horizontal pointer y.

Next, the process advances to step s8.5.4 to determine the value of y and branches. When y is less than or equal to 9, step s8.5 again
．． Return to 2. When y is greater than 9 step s8.5.5
Proceed to step 1, set y to 1 and add 1 to the pointer X in the direction of one line. When the 0 line processing is completed, the pointer l in the document memory BSM will be located next to the delimiter mark. Also, as shown in FIG. 12(1), only "AIUEO" is transferred to the block memory BRM.

Returning to FIG. 7, in Stellar s8.6, horizontal ruled line information for one line is set in the block memory, and block row NoLN is set.
The details of this process of setting O to the value of the next row will be explained with reference to FIG.

In step s8.6.1 of FIG. 9, the contents of the block memory BRM are checked to find a blank line and its line number is set in the block line NoLNO.

Next, the process advances to step s8.6.2, and the contents of the ruled line start flag KSF and ruled line filling flag KTF in the RAM are determined, and it is determined that the ruled line start flag KSF is 1, that is, an intermediate ruled line, and that the ruled line filling flag KTF is 1. This is the end of this routine in order to close the ruled lines from time to time. On the other hand, if the other conditions are met, proceed to step s8.6.3 and mark the horizontal ruled line mark "-".
" is set in all vertical ruled lines from the first digit to the last digit by referring to the vertical ruled line table TXT. After that.

1 is set in the pointer p of the vertical ruled line table TKT.

Further, the process advances to step s8.6.4 and the vertical ruled line table TX is
The contents of T are read according to the pointer p, and the process branches depending on whether the value is the first, last, or middle digit. If it is the first digit, proceed to step s8.6.5.

In step s8.6.5, ``1'' or ``g'' or a space is read from CG and set in the matrix position of block memory BRM defined by block row No LNO and TKT(p). When the ruled line flag KF is 1, all ruled lines are omitted, so a space is inserted.

Determine by. In other words, when the ruled line start flag KSF is O, there is no ruled line above it, so the pointer p is set to 1.
Advance one step. Furthermore, step s8. ．． ．． 6. Return to step 4 and read the next vertical ruled line digit position again.

Set it to BRM. Which pattern to set is determined under the same conditions as in step s8.6.5.

Thereafter, proceed to step s8.6.6.

Set BRM as in step s8.6.5. When this process is completed, the process advances to step S8.6.9, advances the block row NoLNO by one to change the line in the block memory, sets the ruled line start flag KSF to 1, and remembers that the first horizontal ruled line has been transferred. Figure 12 (
As shown in the example of the second line of 2) and the fifth line of FIG. 12(5), horizontal ruled lines are set in the block memory BRK. Once this process is completed, step 38 in FIG.
Proceed to step 7.

In step 88.7, the character string included in the small block in the document memory is stored in the block memory BRK at the same time as the vertical ruled line information.
This will be explained in detail with reference to FIG. 1θ.

First, in step s8.7.1, block memory B
Set the value of block row NoLNO in the horizontal pointer X of RM, and also set the starting digit in the small block range table in the vertical pointer y.
Step 18.7.2 reads the document memory and branches depending on its contents.

In the case of normal characters, the process proceeds to step s8.7.3, where the contents of the document memory BSM are transferred to the block memory BRM. Furthermore, the pointer i of the document memory BSM is advanced by one.

Next, proceed to step s8.7.4 and block memory BRM.
horizontal pointer y and small block range table SHT
Compare with the ending digit. This means checking whether the transfer of one row of the small block has been completed. If they match, the transfer of one line has been completed, and to explain this using the example of FIG. 12 (3), this means that up to the third line rABJ has been transferred.

In that case, the process proceeds to step s8.7.5 and sets all the necessary vertical ruled lines on the transferred lines. After that, the vertical pointer .

On the other hand, when it is determined in step s8.7.4 that one row is incomplete, the process advances to step 58-7.6 and the block memory BRM
Advance the horizontal pointer y by one step and proceed to step s8.
Return to 7.2. By repeating this process, data up to "AB" and "C" are transferred as shown in FIG. 12 (3).

On the other hand, if the content of the document memory BSM is a mark in step s8.7.2, the transfer of one small block is completed and the routine exits.

Returning to FIG. 7, in step 88.8, the pointer m of the small block range table SHT is advanced by one. Furthermore, in step 88.9, step 33-1 is executed, and as a result, it is determined whether all the small blocks arranged in the horizontal direction have been transferred to the block memory BRM. If the transfer has not been completed yet, the process returns to step 88.7. When completed, the small blocks rABcJ rabcJ are arranged horizontally as shown in Figure 12 (4).
has been transferred, the process proceeds to step s8.10.

In step s8.10, the pointer i1 of the document memory BSM is advanced by one and the contents of the next document memory BSM are read.
The process branches depending on whether the content is a mark or not. That is, if it is a * mark, it is two consecutive * marks that were read last in step 58.8, so in that case step s8. Proceed to step 11. If it is not a mark, proceed to step 88.6 again.

Step s8. In ll, the transfer of character information for all blocks is completed, so a process is performed to transfer the ruled line of the last line of the block to the block memory. This process is performed in step 88.6.
In the same way as in , first read and set the ruled line button "-" across one line from the CG, then set the vertical ruled line table T.
Depending on the contents of the KT, the ruled line will be pressed ``S'', ``L'', ``''''
This means that the process of reading and setting the CG from the CG is performed.

When this process is completed, the block memory BRM is completely completed, and the 12th [iii! 1 shown in example (6)
This means that the transfer of lines up to 8 has been completed.

Further, the process proceeds to step s8.12, and the next character with two consecutive delimiter marks is transferred to the block memory BRM as plain text. As a result, the transfer to the block memory is completed as shown in FIG. 12 (6).

In the above-described embodiment, the block memory is a 9×9 matrix, but it may be a matrix of other configuration, and the gist of the present invention will not be impaired even if the LCD of the display device is replaced by another display device, such as a CRT. do not have.

[Effects] As described above, according to the present invention, when converting a document consisting of one serial character string into a block format, only marks of type 1114 can be used to divide the document both vertically and horizontally. It became possible to do it.
