Description

DETAILED DESCRIPTION OF THE INVENTION [Technical Field] The present invention relates to a document processing device, and more particularly to a document processing device having functions for creating and editing external characters.

[Prior art] In conventional devices of this type, by placing the cursor on the position of each pixel (bit) constituting a custom character and pressing the selection key to turn on or off the information for each pixel, the custom character can be changed. It was possible to perform creation and editing operations. Therefore, even if there is a request to rotate the entire external character, it is necessary to move the cursor to each pixel and perform the information ON10FF operation. In particular, when rotating external characters, almost the entire text had to be rewritten, which was extremely time-consuming and labor-intensive.

[Objective J: The present invention has been developed in view of the above-mentioned drawbacks of the prior art, and its purpose is to provide a document processing device that facilitates custom character rotation editing.

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

FIG. 1 is a block diagram showing a document processing apparatus according to an embodiment of the present invention. In FIG.
2 is a read-only fixed memory (ROM) for storing the control procedure of the embodiment shown in FIG. 10, and 3 is a writable random access memory (1 word, 16 bits) used for temporary storage of various data. RAM).

In RAM3, GBUF is a custom character buffer that stores the custom character being processed as a bitmap, and WBUF is the GBUF.
It has the same configuration as , and is a work buffer used as a temporary work area.

4 is a keyboard equipped with character keys and various function keys; 5 is a disk device for storing fixed form documents, etc.;
6 is a cursor register whose contents can be read and written by the CPU, and a CRT controller (CRTC) 8, which will be described later.
displays a cursor on the CRT display section 9 corresponding to the address stored in the cursor register 6. 7 is a data buffer (DBUF) that stores document information etc. input from the keyboard 4; 8 is a CRT controller (which plays the role of displaying the cursor at the location indicated by the cursor register 6 and displaying the document contents stored in the DBUF 7); CRTC
), 9 is a CRT display section using a CRT, 10 is a CRT display [characters displayed on 9].

This is a character generator that generates pattern signals such as symbols and cursors.

With the above configuration, the device of this embodiment operates in response to various inputs from the keyboard 4. When there is an input from the keyboard 4, an interwoven signal is first sent to the CPUI, and
The CPU reads the control program from the ROM 2 and executes it to perform control.

FIG. 2 to FIG. 8 relate to the operation and operation explanation of the device of this embodiment, and are related to the second r! 1J is a diagram showing a CRT display screen during creation of external characters. On the CRT screen, the custom character bit patterns input so far are displayed in an enlarged manner, and in the monitor line MA, menus showing various functions that can be used during custom character processing are displayed.

The bit configuration of the entire external character is 1, for example, an 8 x 8 dot configuration, and each bit's ON10FF display is ON.
is represented by a black circle (fist), and OFF is represented by a dot (.). Here, bit ON refers to the point where the print dot is energized during printing, and refers to the point where the display dot lights up when the CRTJ is displayed, and bit OFF means the point where the print dot is not energized during printing. This refers to the fact that the display dots do not light up when displayed on a CRT.

Note that the functions displayed in the menu can be executed by pressing the corresponding key switches. Furthermore, FIG. 2 shows the state in which Alphabella (rEJ) is processed as a non-standard character.

FIG. 3 shows a state in which the entire alphabet "E" in FIG. 2 has been inverted in black and white as a result of executing the "reverse" function in the monitor MA.

FIG. 4 shows a state in which, as a result of executing the "rotate" function in the monitor line MA, the entire full version of FIG. 2 has been rotated, for example, by 90 degrees clockwise.

FIG. 5 shows a state in which the entire alphabet "E" in FIG. 2 has been scrolled one dot to the right as a result of executing the "right scroll" function in the monitor line MA. The scroll editing in this case uses, for example, a one-dot rotation shift to the right.

Similarly, FIGS. 6, 7, and 8 show the monitor line M.
As a result of executing the "scroll left,""scrollup," and "scroll down" functions in A, the entire alphabet "E" in FIG. 2 is scrolled in each direction.

FIG. 9 is a diagram showing the storage state of the external character buffer GBUF which stores the alphabet rEJ as a bitmap.

FIG. 1θ is a flowchart showing the custom character processing of the embodiment. In FIG. Perform processing, such as moving a cursor.

If it is the edit function key, the process advances to step S3 and it is determined whether the key is the "reverse" key. If it is the "reverse" key, the process proceeds to step S4 and performs the reverse editing process. That is, all bits of the contents of the external character buffer GBUF are exclusive ORed (X
OR)L, the process proceeds to step 310 and the result is displayed on the CRT display section 9. In addition, the contents of GBUF at this time are the 11th
As shown in the figure.

If it is determined in step S3 that the key is not the "reverse" key, the process proceeds to step S5, where it is determined whether the key is the "rotate" key. If the "rotate" key is pressed, the process advances to step S6 and rotation editing processing is performed, that is, the entire contents of the external character buffer GBUF are rotated clockwise by 9
Edit 0 degree rotation.

This relationship is shown in FIGS. 12(A)-(D). To explain step by step, the column bit of column GBUFgJ (the shaded part) is extracted (Fig. 12 (A)), it is stored as the row bit of the work buffer WBUFpj row (Fig. 12 (B)), This transfer method moves bit a7j of the most significant (address) row of the GBUFpJ column to the bit position of the 2nd (address) column of the WBUF, and then similarly moves the bit a7j of the most significant (address) row of the GBUF
Move the bit aaj of the most significant (address) row -1 of the jth column F to the bit position of the least significant (address) column +l of the jth row of WBUF, and in the same manner, GBUF! @ Bit a5j of the most significant (address) row-2 of column j to the least significant (
WBUF! address) line up to bit aoj! Move from the bit position of the lowest (address) column +2 of row $j to the bit position of the highest (address) column (Figure 12 (C))
.

In this way, by repeating the above j from 0 to 7, it is possible to obtain the result of rotating the entire external alphabet "E" clockwise by 90 degrees on the WBUF, and this WBUF
Copy the contents onto GBUF and finish editing (first
2 (CD)), the process then proceeds to step 310 to display the results on the CRT.

If it is determined in step S5 that the key is not the "rotate" key, the process proceeds to step S7, where it is determined whether the key is the "right scroll or left scroll" key. If it is the "scroll right or scroll left" key, the process advances to step S8 to perform right or left scroll editing processing, that is, to edit the external character buffer GBUF by 1 bit scrolling to the right or left. This relationship is the first
3 (A) and (B). To explain step by step, in right/left scroll editing, if the input key is the right scroll key, each line of GBUF is rotated 1 bit to the right and editing is completed (Figure 13 (A)); if the input key is the left scroll key If so, each row of GBUF is rotated to the left by 1 bit and editing is completed (FIG. 13(B)). Next, the process proceeds to step S10 to display the result on the CRT.

In addition, in step S7, "scroll right or scroll left"
If it is not a key, the process advances to step S9 to perform upward or downward scroll editing processing, that is, to edit the external character buffer GBUF by scrolling it up or down by 1 bit upward or downward. This relationship is shown in FIG. 13(C), CD). To explain step by step, in the up/down scroll edit, if the input key is the up scroll key, the θth line and the first line of the GBUF are swapped, and the first and second lines of the GBUF are swapped. Do the same thing from the 2nd row to the 5th row, and finally the 6th and 7th rows.
Finish editing by swapping lines 6 (13th
If the input key is the down scroll key, the 7th and 6th lines of the GBUF are swapped.0 The 6th and 5th lines of the GBUF are swapped. Further, the same process is performed from the 5th line to the 2nd line, and finally the 1st line and the 0th line are exchanged to complete the editing (FIG. 13 CD)).

Next, in order to display the result on the CRT, the process advances to step S10, and the contents of the edited external character buffer are displayed on the CRT display section 9.

Now, in order to display the contents of the external character buffer GBUF on a CRT, turn on the 1-bit determined by the matrix address on GBUF.
10 FF DB where F information is laid out in the same way
It is associated with code information for displaying one character on UF7 (Fig. 1).

That is, if the bit on the GBUF is ON, the code of the corresponding area on the DBUF is converted to a large black circle ".". Also GB
If the bit on the UF is OFF, the sign of the corresponding private area on the DBUF is converted to a black dot ".". This relationship is the 14th
As shown in the figure. By converting all the bits 0N10FF information on GBUF to DBUF in this way, character generator lO is activated and C
A custom character pattern is displayed on the R1 display section 9.

In the above embodiment, the external character bit configuration is 8×8 dots, but other configurations may be used, for example, an nXn configuration such as a 16×16.24×24 dot configuration.

Also, although the 1-rotation processing is performed by rotating clockwise, it may also be rotated counterclockwise.Furthermore, although the rotation processing is performed by rotating 90 degrees at a time, it may be rotated by 180 degrees. ,Although the rotation process is performed on the entire custom character, you can specify a certain range of the custom character and then rotate only the area within the □.In this case, specify a certain square range with the cursor. It is also possible to use a method in which the specified range is rotated by using a means to rotate the specified range and then inputting a rotation key.

Further, although the scroll instruction in this embodiment is performed by pressing a dedicated key, the scroll instruction may be performed by specifying a cursor on the display, for example, ``scroll right''.

[Effect] As described above, according to the present invention, when rotating the entire external character, it is unnecessary to move the cursor to each bit of the external character and rewrite each bit one by one as in the conventional method, which is extremely time-consuming and labor-intensive. The work involved.

This is easily achieved instantly by simply pressing the rotary key. In particular, since the work of obtaining rotated external characters using the conventional method was very complicated, the effects of the present invention are remarkable.

Furthermore, if the rotation result is inappropriate, the user can press the rotation key several more times to return to the original custom character, making it possible to realize a document processing device that dramatically improves the efficiency of conventional custom character work.
