If the user wants to write a sentence in a predetermined item position of a document that has been created once, or wants to write a document in a predetermined item column of a preprinted document, the document must be set in order to set the character position to be input. It was intended to position with a rough guess while looking at it, and whether or not the set position actually matches the predetermined position of the document can be known only by printing on the document.

For this reason, the conventional device is convenient for creating an entire document, but when it is desired to input characters and write a predetermined sentence at a predetermined position of a document that has been printed or printed in advance, the burden on the operator is large and the operability is high. Could never be called good.

<Purpose> The present invention is a document processing which, when characters are input and a predetermined sentence is desired to be written in a predetermined position of the above-mentioned preprinted or printed document, the writing can be facilitated and the burden on the operator can be significantly reduced. The purpose is to provide a device.

Therefore, the apparatus of the present invention is provided with an image scanner for reading a document printed or printed in advance, and the image information of the document read by the image scanner is displayed on a display screen such as a CRT and the document on this display screen is displayed. Document processing in which the position of the input sentence on the document is set by writing the input sentence to the target position, and then the input sentence having the position set is sent to the printing device and written to the target position. A device is provided.

The image scanner can be configured by a device similar to a document reading device such as a facsimile, and more specifically, 8 in the main scanning direction. A line head having a density of dots / mm is provided to feed a read document in the width scanning direction, and a black and white image is read and output as binary data (image data).

9 is, for example, 24 from the character data input by the character keys.
It is a pattern generator (CG) that converts into a pattern of × 24 and outputs the pattern data.
Is supplied to.

Reference numeral 10 is a controller of the CRT 12, and 11 is a display memory to which 1 bit is allocated for each pixel. The display data stores character data whose pattern is expanded by the CG9 from a character data buffer described later and also an image data buffer described later. More image data is stored. This display memory 1
The data of 1 is sent to CRT12 and displayed. The data in the display memory 11 is also supplied to the printer 14 for printing.

Next, FIG. 2 shows a display example on the CRT 12, and an area indicated by 100 on the display screen is the image scanner 8
A display area for displaying the image data read in and the character data of the input text, 101 is an input area for displaying the character string being input, and the text is input and corrected once in the input area 101. When the input and correction of is completed, it is displayed in the display area 100.

Reference numeral 102 denotes a cursor for designating an input position of a character string or a character to be modified, which is moved up, down, left, or right in response to an instruction of a cursor key.

FIG. 3 is a diagram showing a specific configuration of the control RAM 6, the character buffer 4, and the image data buffer 5 shown in FIG.

The control RAM 6 has the following configuration. That is, 20 is a buffer MAXX in which the number of dots in the horizontal direction of the read image data is set, and the movement of the cursor on the screen in the horizontal direction is restricted within this range.

Reference numeral 21 is a buffer MAXX in which the number of dots in the vertical direction of the read image data is set, and movement of the cursor on the screen in the vertical direction is restricted within this range.

Reference numeral 22 is a cursor buffer CURSORX in which the X coordinate value of the cursor position in the read image data is set, and has a range of 1 CURSSRXMAXX.

Reference numeral 23 is a cursor buffer CURSORY in which the Y-coordinate value of the cursor position in the read image data is set and has a range of 1 CURSSRY.

Each buffer indicated by SX of 24, SY of 25, EX of 26, and EY of 27 represents two points of the rectangular portion of the image data currently displayed on the screen, that is, the lower left (L) of the image data of FIG.
In the coordinate system with (1.1) as the origin, the lower left, that is, the L position is (SX.S
Y), and the upper right, that is, R position is shown as (EX.EY)
(The relationship is EX = SX + (M-1), EY = SY + (N-1)). The M and N indicate the numbers of horizontal and vertical dots on the screen, respectively.

28 is a pointer 1 that holds the start address of the buffer in which the input character is stored, 29 is a pointer 2 that holds the address of the buffer in which the next input character should be stored, and 30 is The pointer 3 holds the start address of the buffer in which the read image data is stored.

Xφ of 31 and Yφ of 32 are buffers for temporarily holding the coordinate data on the display stored in the buffer 4 when the data in the character buffer 4 is transferred to the display memory.

33 is a counter (CC) that counts data in the control step of the CPU 1, and 34 is a counter that counts display lines in the control step of the CPU 1.
(CNT), and 35 is a pointer (PT) indicating the position of the image data buffer.

An input buffer 36 temporarily stores the input character data string.

Next, the structure of the character buffer 4 will be described. The character buffer 4 is divided and stored for each character string input at one time, and each character data is composed of 2 bytes. The start coordinates for the data in the image data buffer 5 are assigned to each section.
X ₁ , Y ₁ (40, 41), the number of characters 42, and character data 43 are stored.

These divided data are continuously stored for each input. Further, by transferring only this character data to the display memory 11, only the character data is displayed, and by supplying the data of this display memory 11 to the printer 14, character printing is also performed.

Next, the structure of the image data memory 5 will be described. Image data (white and black are represented by binary data) 50 is stored for each line separated by a line end code (EOL) 51. The above-mentioned pointer 3 (30) holds the position data corresponding to the start address of the image data.

The operation of the document processing apparatus having the above-described configuration, particularly the operation in the case of inputting desired character data to a predetermined position of a preprinted document to complete the target document will be described.

First, the operator mounts a preprinted document of a predetermined format (the document shown in the display example of FIG. 2 in which ruled lines, dates, etc. are printed) on the image scanner 8, and the image is read by the scanner 8 to form an image. It is transferred to the data buffer 5 via the DMAC 7 and stored. Further, as the image data, data corresponding to the display screen of the CRT 12 defined by MXN is transferred to the display memory 11 and displayed on the CRT 12 as shown in FIG. At this time, the buffers MAXX20, MAXY21,
SX24, SY25, EX26, EY27 are set respectively.

Further, although the CURSO RX22 and Y23 are set at predetermined positions on the screen, they are initially located at the upper left and hold their position coordinates.

Further, the pointer 1 (28) holds the start address of the character buffer 4, the pointer 2 (29) holds the input start address of the character buffer 4, and the pointer 3 (30) holds the start address of the image data buffer 5. It

Next, the operator designates the position with a cursor key to input a character (or a character string) at an arbitrary position in the image data. At this time, CURSOR X and Y are updated according to the key operation.

After that, when the cursor is moved to a predetermined position, characters are input. This character input operation is executed according to the flowchart shown in FIG.

Since the display position of the input character is the current cursor position, the value of CURSORX, Y is set at the address position indicated by the pointer 2 as the start position of the character string, that is, 40 and 41 in the character buffer 4 in FIG. Set (301).
Then, the pointer 2 is moved up by 2 to indicate the position of 42 in the character buffer 4 (302).

Following this, the character buffer 4 side advances to the address position where the value of the pointer 2 is incremented by 1, that is, advances to the area indicated by 43 and stores the character data of 2 bytes, and after this storage the address is further increased by 2up. The input character data is sequentially written by this operation (303). At this time, the above-mentioned pointer 2 still indicates the position of 42 of the character buffer 4.

Next, after writing the character data, the number of characters is stored at the address position indicated by the pointer 2, that is, at the position 42 of the character buffer 4, and the pointer 2 is moved up by 1 (304). At this time,
The pointer 2 indicates the head position of the area indicated by 43 of the character buffer 4.

After writing the character data in the character buffer 4 as described above, the character data in the character buffer 4 is generated by the pattern generator.
The pattern is developed by (CG) 9, and this pattern data is sequentially stored in the display memory 11 at the address position of the memory designated by the cursor, and is displayed by the CRT 12 (305 to 31).
3). In the display on this CRT12, it is compared with the buffers (SX.SY) and (EX.EY) which hold the display area of the image data, and only the portion that falls within this area is displayed.

In this way, when the input of the data for one screen is completed, the cursor is moved to display the next screen. This cursor movement is operated in steps 314 and thereafter.

If this is an instruction to move the cursor (300), CURSORX.CURSORY is updated by the specified amount in the specified direction. If the new cursor position is not outside the screen (315), the cursor display is updated (316) and when moving outside the screen, the screen is first erased (317) and the image data buffer 5 is set to include the cursor position. Set the position of (SX.SY), (EX.EY) with respect to and newly set the screen (318).

Then, steps 319 to 333 are newly the flow of displaying the image data on the screen, among which steps 319 to 327 are newly set (SX, SY), (EX, EY). The process of associating the position of the image data buffer 5 corresponding to the pointer with the pointer (PT) 35 is performed, and in steps 328 to 332, the process of transferring the data of the image data buffer corresponding to this screen to the display memory is performed. ing.

By the above-mentioned operation, the image information of the document printed or printed in advance read by the image scanner is displayed on the display screen of the CRT, and the input sentence is written in the target position for the document of this display screen. Is set on the document.

Next, FIG. 4 (b) shows a process of transferring only the data of the character buffer 4 input so far to the display memory 11 and displaying it on the CRT 12 in order to print only the input sentence on the above document. ing.

This is because the display position of a character string input at one time is determined according to their start coordinates Xφ31 and Yφ32, and the number of input characters is the character pattern generator (CG) 9 for each character string.
The pattern is generated by and is stored in the corresponding position of the display memory 11, and is displayed by the CRT 12. Then, the pattern data of the display memory 11 is sent to the printer 14 to be printed, whereby the input character is printed at the set position of the document.

The printer 14 adjusts the relative positional relationship between the image scanner 8 and the image scanner 8 in advance so that the coordinate position read by the image scanner 8 and the printed sheet are completely matched. In particular, if an image reading device and a printer, which are partially visible, are used, the positional relationship between the two becomes characteristic, and the above-mentioned input text is printed at a predetermined position of a document printed or printed in advance. The document can be completed.

<Effect> As described above, in the document processing apparatus according to the present invention, when it is desired to write a predetermined document by inputting characters to a predetermined position of a document printed or printed in advance, the document is read by an image scanner and the document is read. By displaying it on the display screen and writing the input sentence to the target position on the document on the display screen, the position of the input sentence with respect to the actual document can be set and the position of the document can be easily set. The burden on the operator can be significantly reduced. Then, the target character document can be completed by printing the position-set input character data on the character document by a printer, and a document processing device excellent in insertability can be provided.
