Description

DETAILED DESCRIPTION OF THE INVENTION Field of the Invention The present invention relates to a text processing device such as a so-called word processor, and more particularly to a text processing device that is equipped with a CR1 display device and that performs writing, editing, etc. of text.

BACKGROUND OF THE INVENTION When a text is created using a text processing device, characters are first input using character keys on a keyboard, the input characters are edited into a text in a predetermined format, and the text is sequentially stored in a text buffer. The memorized text is then printed by a printer. During this printing, the amount of feed between lines of text, that is, the interval (distance) between lines of text to be printed, is set.

In the printer, paper feed is controlled according to the set feed amount, and printing is performed at the set line spacing.

By the way, a text processing device equipped with a C□RT display device:.

11 When doing a chapter collection, there is an advantage that you can visually recognize the sentences displayed on the CRT display device. Hikashi, 99℃ et al., the place of conventional equipment.

In some cases, the line spacing of the CRT display device, the text □, and the line spacing of the text printed by the printer are not necessarily the same □
Naka, ivy, that doesn't match. That is,,,,C,
R, , T Table 4 The text displayed on the display device is, for example, c;,'
：This is called the code refresh method, and since the number of screens on a CRT is fixed, the line spacing is always constant and cannot be changed, but the line spacing of sentences printed by printers is This is because it can be varied depending on the amount of feed between the lines of the text. Therefore, it is difficult to recognize the line spacing of the text actually printed by the printer on the CRT screen.
This method had the disadvantage that it was particularly difficult to edit the text because the finish of the printed text could not be recognized.

OBJECTS OF THE INVENTION Therefore, an object of the present invention is to make it possible to vary the line spacing of text displayed by a CRT display device, and to change the line spacing of text actually printed by a printer. 'If! To provide a text processing device in which a CRT display device starts displaying text with squares at regular line intervals.

DESCRIPTION OF THE INVENTION To put it simply, in this invention, the line spacing designation □-Is, which specifies the width between the lines of a sentence, is input using a keyboard device. At this time, the line spacing specified by the line spacing data is converted into the number of dots on the dot printer, and the scanning line of the CRT display device is shifted by the number of dots. This is a text processing device that allows the line spacing of text data to be displayed to be variable. ′
□The above-mentioned objects and features of the present invention will become clearer from the following description of an embodiment with reference to the drawings.

Description of examples FIG. 1 is a diagram for explaining line spacing data.

As shown in the diagram, the distance between the first line and the second line of the sentence is
1, that is, the sum of the line spacing and the sentence width as the line break amount,
For example, it is set to 7 to 8 mm. This setting is for the dot printer's □ dot □ G annotation 'sv
With '* base, it becomes □ like '8th trigram 7'1'. In other words, Figure 2 shows the 1st item: c6 'M''line'' - τ dot □
This is an explanatory diagram for calculating the number of dots when converted into a dot arrangement column.

Referring to the m2 diagram, the pattern for 1 female character is 24 x 2 i □
If it is composed of □, then the top:) POBI'm'' line spacing A
is represented by dot 'd' 1 □- from □ to dot d2 - u 9 in ``.At this time, the □ height B of the character butter: is a value specific to the dot printer. .Therefore, the line spacing between line 11 and line 2 [Gλ, □ △-: "'B (' = C)'" □

：1 character is represented by 1 as shown in 1, and each dot string of the character is represented by the dot printer □.
The configuration has a one-to-one correspondence with each scanning line of the RT display device.

Therefore, the line spacing width C calculated above is replaced by the number of dots of the dot printer, and the number of scanning lines corresponding to the number of dots is C.
This can be done by blanking the RT display screen so that the line spacing between the text printed by the dot printer and the text displayed on the CRT display device can be relatively matched. ' □To convert the line spacing C to the number of dots on the printer, do the following. In other words, the line spacing C
If the number of dots in is n, then n E= (A-8) + (E'-D),',

A text baranoa 41 stores text data input from the 11 character input keys and edited by the CPU 2, and stores line spacing data expressed by the number of dots input from the keyboard device 1 and yuyed by the CPIJ 2 for each line. area 42. The text data is printed by the printer 8. A printer control device 7 controls this printer 8. In addition, the printer control unit N7 is
Controlled by U2. Further, the CPU 2 controls the display control unit N5. The display control device 5 is CR7
This is a control section of the display device 6, and a detailed configuration block diagram thereof is shown in FIG.

Referring to FIG. 4, the character memory (CM>101 has a storage area in one-to-one correspondence with the display screen of the CR7 display device 6 and an area for storing line spacing data for each line. Display data consisting of character codes, for example, is stored in storage areas that correspond one-to-one.Character memory 101 is connected to a multiplexer (MPX

The address is controlled by address data from R) 106. At this time, the multiplexer 104
An R/W signal supplied from the controller 100 switches the write/continue output address.

The write address register 105 is the CPU 2 (FIG. 3).
The address information is set by address information supplied from the CRT controller 10o to the CRT controller 10o. Further, the character code addressed and read by the successive j address register 106 is sent to the character generator address conversion circuit (OCA).

It is stored in the A buffer 107.

102 is a character generator (CG), and address data from the above-mentioned character generator address conversion circuit 108 and address data from the CRT controller 1 to roller 100 are supplied to a character generator address circuit (CGADR) 109. Then, a pattern corresponding to the character code read out from the character memory 101 is read out and stored in a character spacing setting circuit (SR) 113 comprising a Gino register or the like. In this character spacing setting circuit 113, for example, after one column of pattern data of 3 bytes (24 dots) read out from the character generator 102 is stored, 4 bits of character spacing data are stored, so that 28
The bit pattern data is created and the image memory (
IM) 103.

In the image memory 103, in synchronization with the raster scanning of the CR page 63, a read 71-' address register (JMRADR) 110. ! :, write address register (IM
WADR) 111 and multiplexer (MPX) 11
The address is set via 2. Multiplexer 112
is switched by the R/W signal from the CRT controller 100. The data read by the successive address register 110 is parallel/serial (P/S)
The signal is supplied to the video circuit 61 of the CR7 display device 6 via the conversion circuit 114. Reference numeral 62 in the CR7 display device 6 is a deflection circuit, which receives a horizontal synchronizing signal (H8YNC) supplied from the CRT controller 100 and a vertical synchronizing signal @ (V
SYNC) to raster scan the CRT 63.

The operation of the embodiment of the present invention having the configuration shown in FIGS. 3 and 4 described above will now be described with reference to the flowchart shown in FIG. 5.

The operation of this embodiment can be divided into "display control operation J" and "image data display space control operation".

The display $ press operation refers to the keyboard device 1 of the text processing device.
(@Figure 3) When there is a text input or edit IIItII input, this is a control operation that edits the input data into a predetermined text format and stores it in the character memory 101 (Figure 14).

This operation is performed according to the flowchart shown in FIG. 5 (Δ). That is, referring to FIG. 5 (A>), in step S1, each time text data is input, it is determined whether the text data includes character data at the beginning of a line.

Then, if the text data includes data at the beginning of the line,
Proceeding to step S2, the line spacing data storage area 42 (fourth
Line spacing to be memorized in figure)! 1 (indicated by A in FIG. 2) is read out. Then, in step S3, the number of line spacing dots is calculated by converting the line spacing width C (FIG. 2) into the number of dots using the calculation method described above. The calculated data on the number of inter-line dots is transferred to the display control device 5 (FIG. 3). At this time, the display control device 5 causes the multiplexer 104 to select the write address register 105, issues a write command to the character memory 101, and stores the data of the number of line spacing dots in the corresponding area of the character memory 101 ( Step 84). Further, the character data is transferred together with the address data of the character memory 101, and the character data is stored in the character memory 101 (step S5).

The text data stored in the character memory 101 in a predetermined text format in this manner is displayed on the CR1 display device 6 (FIG. 3) through an image data display control operation, which will be described next.

Next, the image data storage control operation will be explained with reference to the flowchart shown in FIG. 5(B).

When the image data development control operation starts, in step 310, a command to read the character memory 101 and write to the image memory 103 is outputted from the CRT controller 100 (FIG. 4). Therefore, each multiplexer 1O4 and 112 selects a read address register (CMRADR>10
6 and write address register (CMWADR) 111 are selected. Furthermore, at this time, read address register 106 and write address register 111 are initialized. Then, the line spacing data to be stored in the image memory 103 is successively stored in the buffer 1107.In step 511) and step 812, character data is read out from the character memory 101, and the data is transferred to the character generator address conversion circuit ( O.C.
A>108, and further converted into character generator address data and supplied to the character generator address circuit (CGADR) 109 (step 513). The character generator 102 reads a corresponding one-line pattern template of, for example, 3 bytes from the character generator address circuit 109 and stores it in the character spacing setting circuit (SR) 113.

Furthermore, the character generator 102 inserts a 4-bit space dot to create 28-bit 1-line pattern data (step S'+5>).

Next, in step 816, the data of the character spacing setting circuit 13 is written to the position indicated by the write address register 111 of the image memory 103, and one line is written in the image memory 103, for example, 28 dots x 40 characters). The column address of the write address register 111 is incremented until the write is completed (Step S17. Step 8).
18) The column address of the read address register 106 is incremented and the above operation is repeated (step 819).

In step 817, when data writing for one line is completed, the process moves to step S30. In step $30, it is determined whether writing of all 24 lines of the image memory 103 has been completed, and if not, the row address of the write address register 111 is incremented (step 5).
31) and a step 532) of resetting the column address of the write address register 111 and the column address of the read address register 106 to return to the beginning;
Repeat the above operation.

In step S30, for example, 24×28×40
Once the image data for one line of characters has been developed, the process proceeds to the next state S401. In step 840, the inter-line data of the buffer 107 is read out, and the fill address register 11'1 for this data is incremented by 4 (step 541).
In this case, the self-contained line for this data is skipped, and all are reset in the initial stage. Space driver l=r 0.1 is stored as image data (step 542). Therefore, the step advances to 843, increments the row address of the read address register 106, specifies the reading position of the next row, and then resets the read address register 106.!Include address register 111. (Step $44), and repeat the above operation.

In step 84.2, when the line spacing data is incremented, the display number of the write address register 111 and the CRT
The address obtained by subtracting 24 from the number of display lines n is compared. , and then, if (write address register)>(n-24), that is, if it is determined that the remaining number of lines does not have the display capacity for one line,
Expanding the image data ends and the operation ends.

The data in the image memory 103 that has been divided into one line as described above is then read out in synchronization with the raster scanning of the CRr 63. By controlling the output voltage register 110, the image data of the corresponding RAN is sequentially supplied to the parallel/serial conversion circuit 114, and the video circuit 61
are sequentially supplied to the CRT 63 and displayed on the CRT 63.

By the above-described operation, the text displayed on the CRT display device 6-F can be displayed with an arbitrary line spacing depending on the text collection.

Effects of the Invention As described above, in this invention, the line spacing specified by the line spacing data is converted into the number of dots of the dot printer, and the scanning frame of the CRT display device is shifted by the converted number of dots. The line spacing of text data displayed on the display device can be varied.

Therefore, when creating a text using the text processing device of the present invention, the operator can create the text while checking the input horn state on the CRT display device.
