Description

DETAILED DESCRIPTION OF THE INVENTION Timing ■ This invention relates to a document creation machine that performs document creation and editing processing.

PRIOR ART ■ Conventional document creation machines generally display only a portion of the page being processed for document creation and editing on the screen of the display unit.

However, if only a portion of the page being processed is displayed in this manner, there is a problem in that it is difficult to grasp the layout of the entire page containing the text being created.

Therefore, conventional proposals have been made to provide two types of display sections, one display section displaying a portion of the page being processed, and the other display section displaying the layout of the entire page being processed. (Refer to Japanese Unexamined Patent Publication No. 147771/1983).

However, when two types of display sections are provided in this way,
The problem arises that the configuration becomes complicated and the cost increases.

Therefore, it may be possible to switch between displaying a part of the page being processed and the display layout of the entire page on a single display section, but if you do this, you can simultaneously check the layout of the entire page while documenting. The problem arises that it is not possible to create .

■-Blood This invention has been made in view of the above points, and it is an object of the present invention to enable a document creation machine to perform document creation work in parallel with confirmation of the layout of the entire page being processed, with a simple configuration. With the goal.

In the figure, the key human power determination circuit 20 includes a keyboard 1
The information input from the computer determines whether the information is graphic character information, format information, control information, etc.

Then, according to the determination result, if the graphic character data is SC due to the operation of the graphic character key, the character input control circuit 21 is sent; if the data is edited SI due to the operation of the edit key, the input control circuit 22 is sent.
If the input data is generated by operating another function key, the input data is transferred to the function control circuit 26.

The character input control circuit 21 manages the pointer of the edit buffer 24 based on the edit data DI and function key DF etc. from the edit control circuit 22 and the function control circuit 23, and edits the input graphic character data DC. Set it in the buffer 24.

The character input control circuit 21 also manages the pointer of the layout buffer 25 to determine whether the input graphic character data sc is a character.

Data displayed such as symbols (hereinafter referred to as "character data")
It is determined whether the data is space data or not, and layout data DR corresponding to the result of this determination is set in the layout buffer 25.

The editing control circuit 22 outputs editing data DI such as insertion, deletion, correction, etc. based on the input editing data SI.

The function control circuit 23 outputs function data DF, such as cursor data for instructing movement of a cursor, based on the input function data SF.

The display control circuit 26 receives pointer data DP from the character input control circuit 21 for determining the cursor position;
Inputting the edit data DI from the edit control circuit 22, the function data DF from the function control circuit 23, the graphic character data DC from the edit buffer 24, and the layerer 1 to data D'R from the layout buffer 25, CR' Controls the display of graphic character data DC and layout on the r2 screen. .

This display control circuit 26 is configured as shown in FIG. 3, for example.

In the figure, a microcomputer (hereinafter referred to as "microcomputer") 31 includes a CPU (central processing unit), a program memory (ROM), a data memory (RAM), an Il.
o (input/output device), etc., and controls the display on the CRT 2 based on the program stored in the ROM.

The CRT controller 32 is in charge of controlling the CRT 2, and performs various controls based on the clock pulse CLK from the clock generator 33.

The character generator 34 converts the graphic character data input from the microcomputer 31 via the bus driver '55 into dot data for display in accordance with the rask address signals RAo-RAn from the CRT controller 32. .

Refresh memory (hereinafter referred to as rV-RAMJ) 36
is the data memory for graphic characters,
It is accessed by the microcomputer 31 or CRT controller 32 via the multiplexer 37, and when accessed by the microcomputer 31.

When data from the character generator 34 is written to the address designated by the address data AO-An, and accessed by the CRT controller 32, the address data MA.

The dot data at the address specified by ~AMn is read out.

Another refresh memory V-RAM 3'8
is a data memory for layout, and is connected to the microcomputer 31 or CRT controller 32 via the multiplexer 3.
When accessed by the microcomputer 61, the dot data of the layout data input from the microcomputer 31 via the bidirectional bus driver 40 is written to the address specified by the address data AO' to An'. or the data at that address is transferred to the microcomputer 31.
When the data is read out and accessed by the CRT controller 1 roller 32, one head of data at the address specified by the address data MAo MΔn is read out.

In the case of Nao and Kono, make sure that the data write and read addresses of each V-RA, M3G, and 38 do not conflict.
Even if there is a conflict, data will not be written to areas other than the dedicated area. In other words, V-R and A M3G are in charge of displaying areas other than the layout display area on the display screen of CRT2, and V7-RA
M38 is in charge of displaying the layout display area.

Further, the microcomputer 31 executes the conversion of the layout data stored in the V-RAM 8 into dot data, the details of which will be described later.

The display dot data output in parallel from these V-RAMs 3E+ and 3B is sent from the clock generator 33 to the shift register 41 and 42, which input pulses in units of tons, although the signal lines are not shown. The data is converted into serial data and input to the video control circuit 44 via the OR circuit 43.

This video control circuit 44 generates a video signal by synthesizing the cursor display signal CU from the CRT controller 32 and the display timing signal DT indicating the horizontal and vertical scanning image display period, and the dot data DS from the OR circuit 43. This video signal and the CRT controller 32

In this embodiment, the layout display means is the character input control circuit 21. of FIG. It is composed of a layout buffer 25 and a display control circuit 26.

Next, the operation of the embodiment configured as described above will be explained with reference to FIG. 4 and subsequent figures.

FIG. 4 is a flowchart showing the operations of document creation/editing control and layout 1 to display preprocessing control.

In the figure, the initial setting when the power is turned on is to set the state to a state other than the insert mode (insert off mode), and to set the buffer pointer (BUFP) of the editing buffer 24.
TI) and buffer pointers (B u F P -r 2 ) of layerers 1 to 25 are placed at the beginning.

In this state, a key force from the keyboard 1 is awaited, and if there is a key force, a key force determination circuit 20 determines whether the input data is graph ink character data SC.

If the result of this determination is graphic character data SC, this graph ink character data SC is transferred to the character input control circuit 21.

As a result, the character input control circuit 21 first checks the edit data DI of the edit control circuit 22, and
− mode or not, and if it is insert mode,
Check whether there is data after BUFPTI, 2, and if there is data, shift 1 character from above BUFPTI, 2 to the end of the file (EOF) and write IIUFPT 1.

After emptying BUFP1 and 2, and when there is no data on BUFPT1 and 2 even when not in insert mode or in insert1 to mode, input data is first set in the position specified by BUFP1'1.

Next, the human data is character data, that is, data of graphic characters to be displayed (data other than spaces).
Check if it is, and if it is display data, B
At the position specified by U F P T 2, for example, set roll-(j in hex expression, and if it is display data, set 13 U F P 'r2. For example, set r O2HJ in hex expression. ~do.

After that, 13tJFPTl, increment 2 (+
1) Do.

In this way, the layout buffer 25 has roIH depending on whether the human data is character data or space data.
J or "02H" are stored sequentially.

Figure 5 shows ■-RAM executed by the microcomputer 31 in Figure 6.
This is a flow diagram outlining the data write control to ``16.38''.

In the figure, after initial settings are made by turning on the power, if there is input data, it is checked whether the input data is graphic character data DC, and if it is, the input data is The data is converted into driver 1 data by the character generator 34 and written to a predetermined address of the V-RAM 36.

On the other hand, if the input data is not graphic character data DC, it is checked whether it is layout data DR or not, and if it is layout data DR, it is written into the V-RAM 38 after predetermined data conversion.

Here, the conversion of the layout data DC to driver 1-data will be explained.

First, as mentioned above, V-RAM36. ro 8 is the same address data MAo-MA from the CRT controller ro 2
1 Normal graphic character display as accessed with n is 8 times, including 1 character spacing and 2 line spacings.
It is assumed that each character is displayed as 2 x 2 dots including 2 line intervals, and the layout is displayed as 2 x 2 dots.

Then, since v-Rp, M 36 and 38 are accessed by the same seatless data M 0 to MAn, V
- In the RAM 313, data must be written to the driver 1 for layout display for four characters corresponding to one normal graphic character.

Therefore, in the data conversion routine shown in FIG. 5, when the layout data I)R is input, the data at the 8-pixel I at the address of V-RAM M'y 8 to which the layout data I-D T belongs is converted. The bits corresponding to the layout data DR in the read data are read out via the bidirectional path driver 40, and the bits corresponding to the layout data DR in the read data are changed according to the result of determining whether the layout data I)R is character data roll-IJ or space data r02+1J. and -c2 change,
The changed data is loaded again via the bidirectional bus driver 1' 40 into the read address 71 of v -1-<AM 38.

With that, C1,! ■- with T controller 1 ~ rollerro 2
By accessing I(ΔM 6 and 38, the dot data at the address specified by address data M A O - M A n is read out and converted into serial data by shift 1 to register 41.42. After that, it is input to the video control circuit 44 via the OR circuit 43,
CIζT2 displays data obtained by combining the dot data stored in the V-RAMs 6 and 38.

FIG. 6 is a diagram showing an example of the display on the CR1'' display device i+?2 of the Sentence-7 upper production machine.

In FIG. 13, the display screen P of the CRT display device 2 is divided into a work display area Q2, a work instruction display area R, and a layerer 1 to display area S. A portion of the page being worked on (being processed) is displayed, and the layerer 1- of the entire page being processed is displayed in a reduced size in the layout display area S at the lower left portion of the display screen F]. Area 1' in this layout display area S is the layout of characters etc. displayed in the work display area Q.

In this manner, the layout of the entire page is displayed in a reduced size on the display unit of the document creation machine at the same time as the portion of the page that is currently being worked on during the document creation and editing process.

As explained above, according to the present invention, in a document creation machine, during document creation and 1RWG, it is possible to determine where the part displayed on the screen is in the entire page, and what kind of information it is. Work efficiency is improved by 42 times since you can create documents and work on the riverbed while checking whether the layout is in accordance with the example.
