Reference numeral 27 denotes a main control section composed of, for example, a microcomputer, and the control section controls the above-mentioned respective sections by outputting control signals C1 to C3 based on a control program. Further, the position of each area in FIG. 5 is stored in advance in this control section.

FIG. 6 is a flowchart showing the above control program, and the operation of the apparatus of this embodiment will be explained below based on this flowchart.

First, in step S1, an input key signal from the input means 4 is read, and in step S2, the type of the key signal is determined. In such a determination, when the input key signal is a cursor movement key, a numeric key, or an execution key, the process proceeds to steps S3, S4, and S5, respectively, and, although not clearly shown in FIG. When the end key is a certain end key, the process ends.

In step S3, the cursor position is changed.
Specifically, a key signal from the cursor movement key 7 is sent to the main control unit 27 from the input means 4 to the cursor position management unit 2.
6, and the cursor position is changed within the management section 26 based on the key signal. When the S3 step is completed, the process returns to the S1 step.

In step S4, it is determined whether the current cursor position is in the reference code area 21 or the registered code area 25, and if the cursor is located in either of these areas, the process proceeds to step S6; otherwise, the process continues. returns to step S1. The cursor position is determined by searching the cursor position management section 26.

In step S6, the numerical value inputted from the input means 4 is displayed on the code area where the cursor is located on the display screen. Specifically, the numerical signal input from the input means 4 to the main control section 27 is sent to the display control section 17 together with the control signal C3, and the control section 1
At step 7, the above numerical value is displayed on the current cursor position. When step S6 is completed, the process returns to step S1.

In step S5, it is determined whether or not the current cursor is located in the area indicated by "[reference]" in FIG. 5. If it is determined that the cursor is not located in this determination, the process proceeds to step S7. Such S7
In this step, it is determined whether or not the current cursor is located in the area labeled "[Register]" in FIG. return.
Note that the determination in steps S5 and S7 is based on the fact that the display positions of "[Reference]" and "[Register]" on the screen are stored in advance in the main control section 27, and therefore the cursor position management section 26 This can be done by reading and comparing the positions.

In step S8, the font patterns stored in the first and second pattern memories 13 and 14 are stored in the font memory 1. Specifically, the external character areas 2b and 3 in the font memory 1 that correspond to the numerical value displayed in the registration code area 22 on the display screen
The font patterns stored in the first and second pattern memories 13 and 14, respectively, are written to b. Such S8
When the step is completed, the process returns to step S1.

Returning to step S5, if it is determined in this step that the current cursor is on the display position of "[Reference]", the process proceeds to step S9.

In step S9, the first one from font memory 1,
The font patterns are read into the second pattern memories 13 and 14, respectively. Specifically, font patterns are read from the print pattern area 2 and the display pattern area 3 in the font memory 1 that correspond to the numerical value displayed in the reference code area 21 on the display screen, and are read out from the first and second pattern memories 13. , 14, respectively. When the S9 step is completed, the process returns to S1.
Proceed to step 0.

In step S10, the input key signal from the input means 4 is read as in the first step, and in step S11, the type of the key signal is determined.

In such a determination, if the input key is the first control key 8, second control key 9, or cursor movement key 7, the process proceeds to steps S12, S13, and S14, respectively, and also steps (not shown in FIG. 1) If the pattern change key instructs to change the pattern displayed on the first and second display areas 13 and 14, that is, to invert each dot, the process proceeds to step S15, and then presses the execution key 11 or the cancel key 1.
If it is 2, the process returns to step S1.

In steps S12 and S13, it is determined whether the current cursor is located in the first and second display areas 19 and 20, respectively, and when the cursor is located, the process proceeds to step S1.
If not, the process returns to step S10.

Both of the above judgments are made in the first and second display areas 19 and 2.
Since the position of 0 on the screen is stored in advance in the main control unit 27, this is performed by comparing the stored position with the cursor position in the cursor position management unit 26.

In step S16, compression processing is performed. Specifically, based on the control signal C1, the compression unit 15 converts the 32×32 dot matrix size font pattern in the first pattern memory 13 into a 24×24 dot matrix size font pattern using the compression method described above. The data is compressed and changed into the second pattern memory 14. When step S16 is completed, the process returns to step S10.

In step S17, movement processing is performed. Specifically, based on the control signal C2, the transfer unit 16 reads out a font pattern of 24×24 dot matrix size from the second pattern memory 14 and writes it into the first pattern memory 13 in that form. S17
When the step is completed, the process returns to step S10.

In step S14, the cursor position is changed in the same way as in step S3. When this step is completed, the process returns to step S10.

In step S15, the first and second display areas 19,
The pattern displayed in 20 is partially corrected.
Specifically, a pattern modification unit (not shown in FIG. 1) changes the stored contents in the first and second pattern memories 13 and 14 based on a pattern change key. Specifically, the correction department is Sanyo Electric Co., Ltd.
It can be configured in the same way as the Japanese word processor SWP-3000 manufactured by Manufacturer. When step S15 ends, the process returns to step S10.

Next, in order to facilitate understanding of the above flowchart, the flow of the flowchart will be explained using a specific example.

Here, in one specific example, a ready-made character pattern "turtle" is first read out from the font memory 1, and only the 32 x 32 dot pattern (displayed in the first display area 19) of the character "turtle" is read as "○ turtle". In addition to changing the pattern to 32 × 32 dot pattern “○turtle” 24 × 24
A compressed pattern is created on the second display area 20, and then the above-mentioned pattern is stored in the external character area in the font memory 1.

First, the cursor 25 is positioned in the reference code area 21. At this time, if the cursor 25 is not in the reference code area 21, the cursor can be moved to the above position by operating the cursor movement key 7. This processing is performed by cyclically processing a loop consisting of steps S1, S2, and S3.

Next, input the character code corresponding to the character pattern "turtle", for example "0191", from the numeric keypad 6, and S
After processing steps 1, S2, S4, and S6, the numerical value "0191" is displayed in the reference code area 21 as shown in FIG.

After that, use the cursor movement key 7 to move the cursor 2
5 to the "[reference]" position and press the execution key 11. Steps S1, S2, S5, and S9 are processed, and a "turtle" pattern represented by a 32 x 32 dot matrix is stored in the first pattern memory 13. The font pattern is read out, and a "turtle" font pattern represented by a 24×24 dot matrix is read out into the second pattern memory 14.

Subsequently, in order to modify the font pattern in the first pattern memory 13, the cursor 25 is positioned within the first display area 19. Such movement is performed by operating the cursor movement key 7 at S10, S.
This is executed in a loop consisting of steps 11 and 14. Next, by operating the pattern change key, a loop consisting of steps S10, S11, and S15 is cycled through, and a "turtle" pattern, for example, as shown in the first display area 19 of FIG. 5 is created.

After correcting the pattern, when the first control key 8 is pressed, the current cursor position is within the first display area 19, so steps S10, S11, S12, and S16 are sequentially processed, and the font in the first pattern memory 13 is A compressed pattern of the pattern is written into the second pattern memory 14 and displayed as shown in FIG.

Next, the first and second pattern memories 13,
Move the font pattern stored in 14 to a desired location in font memory 1, e.g. character code "8801".
If you want to store it in a position corresponding to , first press the execution key 11. As a result, the process returns to step S1 from step S10 through step S11. In this state, the cursor is moved to the registration code area 22 on the display screen. Such processing is performed in S1 by operating the cursor movement key 7.
It is executed by sequentially processing steps S2 and S3.
Next, when the character code "8801" is inputted from the numeric keypad 6, steps S1, S2, S4, and S6 are sequentially processed, and the character code "8801" is displayed on the registered code area 22. Thereafter, by moving the cursor 25 to the "[Register]" position and pressing the execution key 11, steps S1, S2, S5, S7, and S8 are sequentially processed, and the font pattern in the first pattern memory 13 is stored in the font memory 1. The font pattern in the second pattern memory 14 corresponds to the character code "8801" in the display pattern area 3 in the font memory 1. written to the position.

Finally, by pressing the end key, the process shown in the flowchart of FIG. 6 ends.

As described above, by using the apparatus of this embodiment, a font pattern having a dot matrix size of 24×24 can be easily obtained by simply creating a font pattern having a dot matrix size of 32×32.

In FIG. 6, when the process advances to step S10, the first and second control keys 8 and 9 are pressed alternately to create a loop consisting of steps S10, S11, S12, and S16, and a loop consisting of steps S10, S11, S13, and S17. By executing loops of steps alternately, a pattern compressed into multiple stages can be obtained.

By adding a pattern enlarging function to the transfer section 16, a 32x32 font pattern can be easily created by simply creating a 24x24 font pattern.

(F) Effects of the Invention By using the present invention, not only can patterns having several different dot matrix sizes be easily created, but also patterns of different sizes can be displayed simultaneously with the dot matrix, so that patterns created as needed can be used. It is possible to modify one of the patterns while referring to the other.
