DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment will be described below with reference to FIGS. Note that this embodiment shows an example applied to a personal computer. FIG. 1 is a block circuit diagram showing the basic configuration of this personal computer.
In the present embodiment, a keyboard 12 and a mouse 12 as a pointing device are provided as external input means of this personal computer. Then, the input information from the keyboard 11 and the mouse 12 is taken into the CPU 15 via the corresponding keyboard control unit 13 and mouse control unit 14.

The keyboard 11 has various keys such as character keys normally provided, and character string data input from the keyboard 11 in a specific mode is transferred to and held in the input character string storage unit 16 under the control of the CPU 15. To be done. The input character string storage unit 16 stores the input character string data in a character code format, and the content thereof is read out under the control of the fixed character string control unit 17, and the character font storage that constitutes the character generator via the CPU 15 is stored. It is sent to the unit 18, converted into a corresponding character font pattern, and then taken into the fixed character string control unit 17.

The fixed form character string control unit 17 stores and holds a fixed form pattern selected in advance by the keyboard 11 or the mouse 12 among a plurality of arrangement patterns (fixed form patterns) fixedly stored in the fixed form pattern storage unit 19. And CR to display the selected standard pattern
The fixed pattern (dotted line) is written in a predetermined position of the T buffer 20. Further, the fixed character string control unit 17 writes the character string font from the character font storage unit 18 into the image buffer 22 via the image control unit 21, but in this case, the character string font is determined according to the selected fixed pattern. Place in position. At this time, the fixed character string control unit 1
Reference numeral 7 determines the arrangement position of the character string font by using various registers provided in the CPU 15, that is, the i, y, x, and n registers, and the character string font is stored in the image buffer 22 according to a fixed pattern. Deploy.

The character string font thus arranged in the image buffer 22 is read by the image controller 21 and written in the CRT buffer 20.
The CRT control unit 23 takes in the data in the CRT buffer 20 and displays it on the CRT display device 24. Further, cursor position data is input to the CRT buffer 20 from the keyboard 11 or the mouse 12 via the CPU 15.

FIG. 2 shows the structure of the character arrangement position table xyp provided in the fixed pattern storage unit 19. This character arrangement position table xyp is provided for each fixed pattern, but in FIG. Only the character arrangement position table xyp corresponding to the pattern is shown, and the others are not shown. A plurality of character arrangement position tables xyp are provided corresponding to the number of input characters arranged in the standard pattern, that is, the maximum number of arranged characters (maxch) indicating the maximum number of characters that can be arranged in the standard pattern is provided. ₀ is 1 character, xyp ₁ is 2 characters ... xy _i-1
Is a character arrangement position table corresponding to the i character. The coordinate position in each of the arrangement position tables xyp ₀ , xyp ₁ ... Is a value (fixed value) from the origin (described later) of the corresponding fixed pattern. Then, each layout position table xyp ₀ , xyp _1, ... Is designated according to the number of input characters according to tblp. Note that tblp is provided corresponding to a plurality of standard patterns and is designated according to ptnp. ptnp designates a selected fixed pattern among a plurality of fixed patterns (four in this embodiment) fixedly stored in advance. In this embodiment, two types of arc-shaped patterns and two types of S-shaped patterns are prepared as four types of fixed patterns, and all of them are curved patterns.

First, the item of "character string input" is selected by the keyboard 11 or the mouse 12 from the processing menu (see FIG. 3A) displayed on the CRT display device 24. FIG. 3A shows a case where the item is selected by the mouse cursor.

When the item "character string input" is selected in this manner, the CPU 15 gives an operation command to the fixed character string controller 17. Then, the fixed character string control unit 17 CRs each fixed pattern stored in the fixed pattern storage unit 19.
Write to T buffer 20, and then CRT control unit 23
Displays the contents of the CRT buffer 20 on the CRT display device 24 as a menu.

Next, a keyboard 11 is used to select a pattern desired by the user from the standard patterns displayed on the menu.
Alternatively, the mouse 12 is used for selection. Then, the fixed form character string control unit 17 takes out and stores the fixed form pattern selected from the keyboard 11, and writes the alternate long and short dash line of the fixed form pattern in a predetermined position of the CRT buffer 20. Then, the CRT control unit 23 causes the CRT display device 24 to display the contents of the CRT buffer 20. FIG. 3B shows the display state at this time. In the figure, PP indicates the pattern origin.

Then, a character string arranged along the standard pattern selected as described above is input from the keyboard 11. Then, the CPU 15 stores the input character string in the input character string storage unit 16, and then the fixed character string control unit 17 executes the operation according to the flowchart shown in FIG.

First, the fixed character string control unit 17 has the CPU 15
The number of input characters obtained by is set in the n register (step S1), and then the x coordinate and the y coordinate of the mouse cursor position are set in the corresponding x register and y register (step S2). Next, ptnp corresponding to the selected fixed pattern is designated (step S3), the maximum number of arranged characters (maxch) of the fixed pattern is read from the fixed pattern storage unit 19 and compared with the number of input characters in the n register (step S3). S4). As a result, when the number of input characters exceeds the maximum number of arranged characters, it is not possible to arrange all the number of input characters in the specified fixed pattern, so the end of the input character string is truncated and the maximum number of arranged characters is set as the number of input characters n. It is set in the register (step S5). After that, when tblp in the fixed pattern storage unit 19 is designated according to the value of the n register (step S
6), character arrangement position table xy corresponding to the number of input characters
p is specified.

Then, the fixed character string control unit 17 reads the input character string code from the input character string storage unit 16 character by character, converts it into the corresponding character font using the character font storage unit 18, and at the same time The process of obtaining the arrangement position (writing position of the image buffer 22) and writing the characters one by one in the image buffer 22 is repeated for the number of input characters (steps S7 to S11). First, the i register is cleared to specify the first character of the input character string (step S7), the first character is read from the input character string storage unit 16 according to the value, and the character font storage unit 1 is read.
8 is used to convert to a character font (step S9).
Then, the writing position for writing this character font in the image buffer 22 is obtained. That is, the specified character position table xyp (e.g., xyp _i-1) reading the coordinate position in the region corresponding to the value of the i register of the _{(x i-1, y i} -1), this x, The writing position (x _i + x, y _i +) is added to the mouse cursor position coordinate (x, y) set in the y register.
y) is calculated. Since the value of the i register is "0", the coordinate position (x ₀ , y ₀ ) is read from the character arrangement position table xyp, and the writing position is (x
₀ + x, y ₀ + y). Here, the coordinate position in the character arrangement position table xyp is based on the pattern origin shown in FIG. 5, and the writing position (x _{0 found at} the clicked position of the mouse cursor is the pattern origin (x, y). + X, y ₀ + y) is a value based on the starting point coordinates (0, 0) of the image buffer 22. The leading character font is written in the image buffer 22 at the writing position thus obtained (step S10). And
After executing the increment process (step S11) for incrementing the value of the i register by "1", the process returns to step S8.

After that, the same operation is repeated for the number of input characters. As a result, as shown in FIG. 5, the clicked position of the mouse cursor is set as the pattern origin in the image buffer 22, and the input character string font is standardized character by character. The patterns are sequentially arranged. Then, when the above-described writing process for the number of input characters is completed, that is detected in step S8, and the process by the fixed character string control unit 17 is completed.

When the input character string font is written in the image buffer 22 according to the fixed pattern in this way, the image control unit 21 transfers the data in the image buffer 22 to the CRT buffer 20. As a result, the CRT control unit 23 sets the data in the CRT buffer 20 to C
It is displayed on the RT display device 24. FIG. 3 shows the display state at this time, and the input character string font is arranged and displayed along the standard pattern with the position where the mouse cursor is clicked as the pattern origin. When the number of input characters is 3, the positions (x ₁ , y ₁ ), (x ₃ , y ₃ ), (x
Character fonts for 3 characters are arranged in ₅ , y ₅ ).

[0019]

According to the present invention, when arranging and outputting a character string, the character arrangement position according to the number of characters in the character string is automatically determined by selecting the output arrangement form desired by the operator. It can be output, and the character layout output can be automatically performed according to the number of characters.
