Description

[Detailed Description of the Invention] [Technical Field] The present invention relates to a document processing device, and particularly to a sorting process in which document information is divided into arbitrary blocks and sort units, and the arrangement of one block is made to follow the arrangement of other blocks. The present invention relates to a document processing device that enables the following.

2. Description of the Related Art In recent years, portable document processing devices equipped with a one-line display have become popular. It would be convenient if this type of device could freely manipulate the character arrangement, but in the past, it only had a sorting function; for example, the number of characters in one line was determined in advance as a sort unit, and each , or sorting by display character string as a unit. Therefore, it is inconvenient to freely manipulate and edit the character arrangement.

"Purpose" The present invention has been made in view of the above-mentioned drawbacks of the prior art, and its purpose is to divide document information into blocks of arbitrary length and sort units divided into blocks of arbitrary length,
It is an object of the present invention to provide a document processing device that enables tabular operations on a document arrangement by making it possible to make the arrangement of other blocks follow the sorting order as a result of sorting blocks.

[Embodiments] Hereinafter, embodiments of the present invention will be described in detail with reference to the accompanying drawings.

FIG. 1 is a block diagram of a document processing apparatus according to an embodiment of the present invention. In the figure, 1 is a keyboard for inputting document information and processing commands, 2 is a liquid crystal display (LCD) that displays one line of document information, 3 is a controller for LCD 2, and 4 is for converting character codes into character patterns. Then L
Character generator to supply to CD or printer,
5 is a central processing unit (CPU) that controls the main control of the nut flow side device; 6 is a ROM that stores the processing program of the embodiment shown in FIGS. 6 and 7; and 7 is necessary for processing. A RAM temporarily stores various types of data, and 8 is a printer that prints out document information.

The RAM 7 includes a document memory BSM that stores document information as shown in the figure, a large block number counter DS that counts and stores the number of large blocks (described later), and a small block that counts and stores the number of small blocks within the large blocks. Number counter SS and
A sort work memory SWM that temporarily saves character strings in sort units, a sort order memory SJM that stores the sort order of sort results, and a pointer memory PNO that stores and updates the sort start position when a sort program is executed.
A storage area such as a cursor position memory CRLM indicating the cursor position on the document memory BSM is provided.

FIG. 2 is a front view of the keyboard 1. In the figure, 1
1 is a character key for inputting normal document data,
The character code corresponding to each pressed key is stored in the document memory BSM and displayed on the LCD 2 at the same time. character key 1
12 of 1 is a mark key "・" for dividing document data into large blocks that are one processing unit, and 14 is a mark key for dividing character strings in a large block into small blocks that are sort units. It is "■". In addition, 13 is a sort key that starts a series of processes for sorting one predetermined block and 8H1 for rearranging the character arrangement of other blocks based on the sorting result. 1) is a cursor for moving the display cursor left and right. This is the key.

FIG. 3 is a diagram showing some details of the RAM 7.

In the figure, document memory BSM is a memory in which character information is stored, and in address order from the beginning BSM (1), BSM
(2) Along with . . . , character information at an arbitrary address i is expressed by BSM(i). Further, the document memory BSM is a serial memory that stores character information strings in the form of one line, especially for the purpose of sorting as will be described later. Therefore, according to the example, it does not include information codes that would not normally be sorted, such as a "line feed" code. Of course, as another example, even if the document memory BSM contains information codes that are not subject to sorting (normal document memory), such codes may be ignored during sort processing. For example, you can obtain results that are better than the actual results. The sort work memory SWM is a serial memory in which, for example, character information strings of small blocks that are moved for sorting within an l block are temporarily saved and stored, and in the same way, SWM (1), SWM (2
] , . . , character information at an arbitrary address i is expressed by SWM(i). The sort order memory SJM is ■
This is a serial memory that stores in the order of sort results the number of sort units that each sort unit that is lined up in order is before sorting when blocks are sorted. Similarly, SJM (1), SJM (2), SJM (2), etc. ..., the order information at arbitrary address i is S J M (i
).

Further, in the pointer memory PNO, the positions of marks "." and "O" which are divided into large and small blocks of the document take are stored as the sorting and arrangement processing progresses.

FIG. 4 is a diagram showing the functional configuration and processing of the embodiment of FIG. 1. In the figure, the document data in the document memory BSM is divided into large blocks by inputting the mark key 12 at each cursor position, and divided into small blocks in sort units by inputting the mark key 14. In this state, the sort range division mark insertion means 21 and the sort unit division mark insertion means 2
2 is shown in the manner in which mark insertion processing is performed in the BSM.

Next, when the sort key 13 is pressed, the sorting and arranging means 2
3 works, and the document data is sorted and arranged. The document memory BSM stores the document data resulting from sorting and arrangement.

□ FIGS. 5(a) to 5(g) are diagrams showing a specific example of document sorting and arrangement according to the functional configuration of FIG. 4. Fifth
As shown in Figure (a), a character string is first input into the document memory BSM in the concept of one column, and then the character string in the document memory BSM is divided into large blocks and small blocks using mark keys 12 and 14. Alternatively, when a character string is input, the mark keys 12 and 14 may be input at the same time. The mark "." has the meaning of dividing the document data into character strings in the sorting and arrangement range, and the mark "O" has the meaning of dividing the character strings within the range into sort units. In this way mark "・
" is defined as a large block, and the mark "
A character string separated by "O" is defined as a small block.

Next, when the cursor is placed at an arbitrary position in the first large block and the sort key 13 is pressed, the sorting and arranging means 23 first compares the sizes of the small blocks in the large block and sorts them, and then the sorting result is Make other block arrays in the same order according to the order. The O 2 treatment result in this case is shown in FIG. 5(C). In this case, the number of characters in the sort unit may be different.

If the number of characters is different and there is no corresponding character in the sorting unit of the other party to be compared, it may be determined that the character is always determined to be large or small. Place the cursor at the second large block in Figure 5(b) and press the sort key 13 to display Figure 5(b).
It is easy to see that the sorting and arrangement results as shown in d) are obtained.

In addition, Figures 5(e) to (g) show the character strings shown in Figures 5(b) to (d) in a different way, with large blocks as rows and small blocks as columns. It is.

FIGS. 6 and 7 are flowcharts 1 showing the processing procedure of the embodiment executed by the CPU 5 of FIG. 1. Further, FIG. 8 is a diagram showing changes in the contents of each memory as the sorting and arranging processing of FIG. 7 is executed. The operation will be described below with reference to these figures.

When the device is powered on, the process first proceeds to step S1 in FIG. 6, where a series of initialization processes are performed. That is, document memory BSM,
The sort work memory SWM, sort order memory SJM, etc. are cleared, the cursor position memory CRLM is initialized, and the cursor is displayed at a predetermined position. In step S2, a key input from the keyboard 1 is waited for, and when a key input is received, it is determined in step S3 whether or not it is a sort key. If it is determined that the key is not a sort key, the process advances to step S4 and normal character key processing is performed. That is, key input characters are stored in document memory B.
It is stored in the address corresponding to the cursor position memory CRLM of SM, and then the cursor is incremented by one. The same applies to the input of mark keys 12 and 14. Also, if it is a sort key in the determination in step S3, step S
Proceeding to step 5, the document memory BSM is sorted and arranged.

FIG. 7 is a flowchart showing details of the sorting and arrangement processing of FIG. 6. In the figure, in step S51, the number of large blocks is determined from the number of marks "." in the document memory BSM, and is set in the large block number counter DS in the RAM area. In step S52, the number of small blocks included in one large block is determined from the number of marks "o" sandwiched between marks "." and is set in a small block number counter SS. In step S53, for example, by placing the cursor, the first character of each small block (sort unit) in the large block specified on the document memory BSM by the contents of the CRLM is compared, and if they are the same, the second character is For example, the smallest small block is found by sequentially comparing the numbers, and its block number is stored in the sort order memory SJM(1). The states of the document memory BSM and sort order memory SJM at this time are shown in FIG.
). In the figure, for example, when comparing "sashisu seso", "kakikuke", and "aiu", the third small block "aiu" is the smallest, so 3 is entered in SJM (1), and similarly, SJM (2 ) is filled with 2 for ``kakikuke,'' and SJM (3) is filled with 1 for ``sashisu seso.''

Next, in step S54, the position of the first mark "fist" in the document memory BSM is set in the pointer memory PNo. This state is shown in FIG. 8(b). In step S55, the small blocks are sorted (arranged) in the order stored in the sort order memory SJM for the large blocks on the right side (larger address side) of the position indicated by the pointer PNO. At this time, the character strings in the sort unit are temporarily saved in the sort work memory SWM, and the operations of inserting them into the document memory BSM again are repeated to replace the character strings in each sort unit. The arrangement result of the first large block is shown in FIG. 8(C). Step 356
Now mark the next large block in the pointer memory PNO.
Set the Φ” position. The state is shown in FIG. 8(C). In step 557, since sorting (arranging) within one large block has been executed so far, 1 is subtracted from the large block number counter DS, and it is determined whether the number of large blocks DS is one remaining. If it is not one, return to step S55 and repeat until DS becomes one. When this process is completed, the sorting (arrangement) is completed, and the data in the document memory BSM becomes as shown in FIG. 8(d).

Although the sorting method in the above-described embodiment was performed in order from the smallest number of characters, the characters may be arranged starting from the largest number, or may be arranged in descending order of the number of characters or in descending order of the number of characters.

Furthermore, although the sort key 13 is used to perform sorting, for example, a character key may be used to input a command such as ``SORD PAPER'' or ``SORT''.

[Effect] As described above, according to the present invention, document information is divided into blocks of arbitrary length and sort units divided into blocks of arbitrary length, and the lpro Since it is possible to perform processing such as making the arrangement of other blocks follow the sort order resulting from sorting a small amount, it becomes possible to perform tabular operations on the document arrangement, greatly expanding document editing capabilities.
