[Explanation of display screen and document data (Figure 2)] Figure 2 (A
) (B) is a diagram showing the relationship between the display screen and the document data area.

In FIG. 2(A), 20 indicates the displayable area of the display unit 6, 21 indicates the document data stored in the TX-1 (PM-1), and 23 indicates the area in which the display unit 6 can display. The origin 22 of the document data in the text memory TX-1 indicating the stored document data is given by (a, b),
The origin 24 of the document data in the text memory TX-2 is (C

FIG. 2(B) shows a case where the display area is designated in FIG. 2(A).

The starting point 26 (m, n) and the ending point 27 (
M, N), the document data 21 and document data 23 contained in the display area 28 are sent to the video memory 5 and displayed on the display section 6.

[Description of Synthesis Processing (FIGS. 2 and 3)] FIG. 3 is a flowchart of the composite display processing of two document data in the word processor of the embodiment.

When composition processing is instructed from the keyboard 2, step S1
, waits for input of the mode key MOD on the keyboard 2, and stores the composition mode instructed by the mode key MOD in the mode 43 of the RAM 4. In step S2, as shown in FIG. 2(B), it is checked whether a display start point indicating the display area 28 has been input. When the starting point is input, the process advances to step S3, where the display starting point is set to (m, n), the column direction address pointer ADPX=m, and the row direction address pointer ADPY=n. If the display start point is not input, proceed to step s4 and enter the display start point (m, n).
(0,0) and set ADPX=ADPY=O. This corresponds to the starting address of the video memory 5.

In step S5, in the same way as in step S2, it is checked whether the end point of the display area has been input. If the 0 display end point has been input, the process advances to step s6, and the input display output point is set as (M, N). do.

If the display end point is not input, proceed to step S,
Let the display end point (M, N) be the final address of the video memory 5. Therefore, when the display area 28 is not specified, the entire video memory 5 is displayed on the display section 6.

Next, in step S8, it is checked whether the pattern data of PM-1 obtained by pattern-expanding the text memory TX-1 is within the display area. If it is within the display area, step S9
Proceed to PM-1 address (A D P
, ADPY-b) is stored in the dot pattern register DRG-1.

If the data of PM-1 is not within the display area in step S8, the process advances to step S10 and DRG-1 is set to "O".

Similarly, in step Sll, it is checked whether the pattern data of PM-2 obtained by pattern-expanding the text memory TX-2 is within the display area. If it is within the display area, the process advances to step S12, and the address of PM-2 (ADPX-c , ADPY-d
) is stored in the dot pattern register D.
Store in RG-2. If the data of PM-2 is not within the display area in step Sll, the process advances to step S13 and DRG-2 is set to o''.

Next, in step S14, the dot data of DRG-1 and DRG-2 are synthesized according to the synthesis mode of mode 43. This includes, for example, logical product, logical sum, exclusive logical sum, etc. of 1-bit data. In step S15, the dot data obtained in step S14 is written into the video memory 5. In step 316, the column direction address pointer ADpx is incremented by 1, and in step S17 it is checked whether the value of ADPX has become equal to the final address.

If it does not correspond to one line of the display area, the process returns to step S8 and performs the above-mentioned operation, but when the processing for one line of the display area is completed, the process proceeds to step S1B, where the address pointer ADPY in the row direction is incremented by 1 and ADPX is also added. The processing of the dot data corresponding to the display area is thus completed, and the entire compositing process is completed.

It goes without saying that a printout of the document data can be obtained by connecting an image printer or the like that inputs and prints image data in the form of dot pattern data and outputs the image data in the video memory 5.

As explained above, according to this embodiment, the coordinate positions of each document data can be set independently, and the respective document data can be combined to create a screen for display output or printout. You can express documents in a way that would otherwise be impossible.

Note that if the coordinate position of the document data mentioned above includes the line pitch, character pitch, etc. in addition to the origin, more free document expression can be realized.

[Effects of the Invention] As described above, according to the present invention, document data can be freely arranged and document data can be synthesized.
