FIG. 2 shows an embodiment of the character processing apparatus of the present invention. Here, the CPU is a microprocessor, which performs arithmetic and logical judgment for character processing and controls each component connected to the bus BUS via the bus BUS. Bus BUS
Is a common bus consisting of an address bus, a control bus, and a data bus, and is used to transfer address signals, control signals, and various data between devices connected to the bus BUS.

KB is a keyboard for inputting characters and control instructions, and is provided with a character input key group such as alphabet keys and kana keys, and a function input key group such as cursor movement keys and kana-kanji conversion keys. Various slide switches such as a paper size switch WSW and a print start position switch PSW shown in FIG. 3 described later are provided.

The ROM is a read-only memory, and the control procedure of the microprocessor CPU shown in FIGS.

The BUF is a document memory and stores a character string input from the keyboard KB. CG is a character generator and is used to generate a character signal of a character pattern having a dot configuration corresponding to character codes such as characters and symbols and cursors stored in the display memory VRAM. RAM is a writable random access memory, which is used as a temporary memory for various data from each component and a work memory for microprocessor CPU operations.

The display memory VRAM stores the display data created by the microprocessor CPU according to the contents of the above-mentioned document memory BUF and the indication values indicated by the paper size switch WSW and the print start position switch PSW of the keyboard KB. CRTC is a CRT controller, which converts the contents stored in the display memory VRAM into character pattern data using the character generator CG and displays it on the display unit.
Performs display drive control to display characters and symbols on the CRT screen. This display CRT is an image display device that uses a cathode ray tube, liquid crystal, light emitting diode, and so on.

Further, the PRT is a printer, and under the control of the microprocessor CPU, the content stored in the document memory BUF is converted into a character pattern by the character generator CG and printed in a predetermined area on the printing paper.

FIG. 3 shows an example of the layout of the above-mentioned keyboard KB. The illustrated paper size switch WSW is an instruction switch for instructing the width of the paper at the time of printing, and the print start position switch PSW is an instruction switch for instructing the distance from the left end of the print paper to the print start position. These two switches WSW and PSW respectively specify the paper size or the print start position in units of even characters. That is, in the example of FIG. 3, the paper size is designated as a width of 16 characters, and the print start position is designated as the fourth character from the left end of the paper.

FIG. 4 shows an arrangement configuration example of the above-mentioned document memory BUF. In this example, as shown in the figure, each line has 10 characters and has a capacity of 10 lines. The character code of a character string such as a character or symbol keyed in from the keyboard KB is temporarily stored in the document memory BUF, and when the screen is displayed, the stored content is transferred to the display memory VRAM by the microprocessor CPU and then displayed. Displayed on the screen of the CRT. The transfer position of the character code when transferred from the document memory BUF to the display memory VRAM is determined by the value indicated by the print start position switch PSW. However, the print start position in the line direction at the time of printing is fixed in this example, and 1 to 10 lines of the document memory BUF are the display memory VR.
Only the print start position in the column direction is changed, as it is transferred to the 2nd to 11th rows of AM.

FIG. 5 shows an arrangement configuration example of the above-mentioned display memory VRAM. This display memory VRAM has 16 characters per line and a capacity of 12 lines as shown in the figure. Display memory VRAM
The content of is displayed on the screen of the display CRT with the positional relationship of this arrangement unchanged.

FIG. 6 shows a paper frame corresponding to the width size of the print paper designated by the above-mentioned paper size switch WSW.
An example of the character pattern used to display on the screen of the CRT is shown below. These paper frame patterns are stored in advance in the character generator CG as a part of the character pattern of the character generator CG together with other character patterns. The first pattern P1 is the upper left corner of the paper frame, the second pattern P2 is the upper right corner of the paper frame, the third pattern P3 is the lower left corner of the paper frame, and the fourth pattern P4 is the lower right corner of the paper frame. Each is used to display the paper frame on the display CRT in a manner similar to the actual paper. Further, the fifth pattern P5 is used to display the left end and the right end of the paper in each line, and expresses the width size of the paper. The sixth pattern P6 is used to indicate the boundary between the upper and lower edges of the paper.

In FIG. 7, a specific character code corresponding to the paper frame display pattern shown in FIG. 6 is used to create a paper frame in the display memory VRAM when the indicated value of the paper size switch WSW is "16". The state is indicated by a pattern. Also,
For example, when the paper size switch WSW is set to "14", the character code corresponding to the second, fourth and fifth patterns P2, P4 and P5 of FIG. It is created as a frame indicating the right edge of the paper at the 14th character string of VRAM. At this time, the 15th character string and the 16th character string of the display memory VRAM are outside the paper size, so they are set to blank codes. In this way, the paper frame is created in the display memory VRAM according to the instruction value set by the paper size switch WSW, converted into the pattern shown in FIG. 6 by the character generator CG, and then displayed on the display CRT. It

Next, as an example, when the paper size switch WSW is set to "16" and the print start position switch PSW is set to "4" with the character string contents of the document memory BUF as shown in FIG. The procedure for creating display data in the display memory VRAM as shown in FIG. 9 will be described with reference to the flowcharts shown in FIGS.

The flowchart of FIG. 10 shows the overall operation procedure. First, when the power is turned on, the process (step) S1 is first executed to initialize various data areas of the memory such as random access memory RAM, document memory BUF, display memory VRAM, and character processing such as input editing. Is possible.

In the next process S2, the process of key input from the keyboard KB is performed, and the input editing process corresponding to the key code input by the key is executed in the subsequent process S3. Since these processes such as input editing are realized by a known technique, detailed description thereof will be omitted.

Since the document memory BUF has been changed by the input editing process performed in the above-mentioned process S3, the content thereof is displayed in the next process S4 via the display memory BUF, and the key input in the above-mentioned process S2 is performed. Return to.

The flowchart of FIG. 11 shows the details of the tenth process S4. First, in process S4-1, the display memory VRAM is cleared once, and preparations are made to display the latest information.
Next step In S4-2, keyboard KB paper size switch WS
Enter the paper size instruction value set in W. In this example, the indicated value is “16”. This paper size instruction value is passed to the next step S4-3 and used to create a paper frame in the display memory VRAM. In this example, the paper frame is formed in the display memory VRAM in the character code form as shown in FIG.

Next, in process S4-4, a print start position designation value by the print start position switch PSW for designating the left margin width of the paper at the time of printing is input from the keyboard KB. In this example, the print start position instruction value is set to "4". This designated value "4" is passed to the next process S4-5. In process S4-5, the content of the character string in the document memory BUF (see FIG. 8) is transferred to the display memory VRAM as it is with the print start position instruction value input in the previous process S4-4 as the reference of the transfer start column position ( (See FIG. 9). In this example, the value of the switch PSW is set to "4", so the first character of the document memory BUF is 4 of the display memory VRAM.
It will be transcribed in the character area. Since the line position is fixed, the first line of the document memory BUF is the second line of the display memory VRAM, the second line of the document memory BUF is the third line of the display memory VRAM, and so on. It is posted. With such a positional relationship, the content of the character code of the document memory BUF of FIG. 8 is sequentially transferred to the paper frame of the display memory VRAM as shown in FIG. 9, and then the content of the display memory VRAM is referred to the character generator CG. Then, it is converted into a pattern and displayed on the screen of the display CRT. At this time, since the storage area of the display memory VRAM and the display area of the display CRT are made to correspond to each other, three spaces are left at the left end of the printing paper before printing and three spaces are left at the left end. It can be confirmed on the display screen that there are characters.

FIG. 12 is a detailed flow of the process S4-3 in FIG. 11, showing a process in which the paper frame code is stored in the display memory VRAM according to the paper size switch WSW. In process S4-3-1, the pattern P1 which is the paper frame code of FIG. 6 is stored in the upper left corner. In process S4-3-2, the pattern P5 of FIG. 6 is stored in the first character string of the 2nd to 11th lines. In process S4-3-3, the pattern P3 of FIG. 6 is stored in the lower left corner. Processing above
The paper frame is set on the left side by S4-3-1 to S4-3-3.
Next, in process S4-3-4, the upper and lower paper frame patterns P6 are used, and the number of patterns P6 obtained by subtracting “2” from the value indicated by the paper size switch WSW is set as the first line of the display memory VRAM.
Store in line 12. Further, in process S4-3-5, the pattern P2 of FIG. 6 is stored in the upper right end position of the paper frame designated by the paper size switch WSW, and in the present embodiment, it is stored in the 16th character string of the first line. In the next step S4-3-6, the frame pattern on the right side
P5 is stored from the 2nd row to the 11th row. The storage position of the pattern P5 in the column direction is the position indicated by the paper size switch WSW, and in the present embodiment, the 16th position of the display memory VRAM is used.
It becomes the character string. In process S4-3-7, the pattern P4 is stored in the lower right corner of the paper frame.

The sheet frame is set in the display memory VRAM by the above description S4-3-1 to S4-3-7.

FIG. 13 is a detailed flow of the processing S4-5 shown in FIG. 11 when the contents of the document memory BUF are transferred to the display memory VRAM. In FIG. 13, in determination S4-5-1, the document memory BU
Judgment is performed to prevent the number of characters in one line of F and the right end of the character string to be displayed by the print start position switch PSW from overlapping the paper frame. If the paper frame has a sufficient area, the number of transferred characters "0" per line is set in the temporary storage area CMAX by the process S4-5-2. If all the number of characters is transcribed and it overlaps the paper frame, the number of characters to be transcribed is limited and not displayed in step S4-5-2. At this time, the number of characters to be transcribed depends on the paper size switch WS.
By setting the value indicated by W minus the value of the print start position switch PSW, the characters that overlap the paper frame or are on the right side of the paper frame are displayed in the memory in the subsequent processing S4-5 to S4-6. Not posted to VRAM.

In process S4-5-4, the counter k for counting the number of characters to be transferred for each line when the contents of the document memory BUF is transferred to the display memory VRAM is set to "0". Next process S4-5-5
Then, one character in the document memory BUF is transferred to the display memory VRAM. In process S4-5-6, "1" is added to the counter k for the transfer position to the display memory VRAM. Processing above S4-5-4, S4-5-
5 and S4-5-6, the contents of the document memory BUF are transferred to the display memory VRAM in order from the first line to the tenth line by the counter I for controlling the number of lines and the counter J for controlling the number of transcribed characters.

As described above, the result of executing the character input editing process by the key input from the keyboard KB is
Since it is displayed on the CRT at the designated display position with the print paper frame each time, it is possible to edit the document while always checking the print image.

In the above-described example, the paper size is specified only by the width in the horizontal direction and the length in the vertical direction is fixed, but the size in the vertical direction is similarly specified. It is also possible to specify not only the horizontal print start position but also the vertical print start position. In this example, the display position of the paper frame and the print start position are specified in units of one character.
If a display device such as a map display is used, it is possible to specify in smaller units (bit units). Further, in the case of a bit map display, it is possible to display on the display CRT even in the case of a large paper by reducing the entire display content.

Further, in this example, the paper size and the print start position are specified by the specific slide switch, but the specified value is determined by the combination input of the alphanumeric key on the keyboard KB and the specific key. Of course, it is okay.

As described above, according to the embodiment of the present invention, the frame indicating the right end of the printing paper and the blank area are displayed according to the size of the paper size designated in advance. During the input editing process, the printing state at the time of printing can be easily confirmed without printing on paper, and as a result, the inconvenience of repeatedly printing is eliminated. As is clear from the above description, when the vertical length of the paper is input or the print start position in the vertical direction is designated, the number of characters to be displayed in the vertical direction is limited.

[0037]

As described above in detail, according to the present invention, it is possible to control the display of the positional relationship between the character string arrangement start position and the character line arrangement start position and the area in the layout state. You can now easily check the print layout at that time.
