Abstract

PURPOSE: To improve the throughput of user character generation by adding a line-by-line deleting function and a shift function for an external character pattern. CONSTITUTION: When key input is done in user character generation mode, a user character is deleted and shifted, line by line. For example, part of a pattern 'X', i.e., a line area 7 is deleted entirely and the lines below the line are shifted up, line by line, to obtain a pattern 2. Then the lines on the right side of a longitudinal line area 8 are moved to the left, line by line, to obtain a pattern 3. Through the deleting and moving operation, the pattern 1 is reduced into a pattern 3. Thus, dots can be turned off by the lines of the external character pattern, so the operation efficiency of external character modifying operation is greatly improved.

Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to the improvement of Japanese word processors, personal computers, hand belts, DPS (data processing systems), and various other data processing devices, and in particular to character generators. By providing a line-by-line deletion function and a line-by-line shift function in a data processing device that has a function for creating characters (external characters) that are not registered in the , so-called user characters.

The present invention relates to a data processing device that improves the operational efficiency of user character creation.

Conventionally, Japanese word processors, personal computers, and other data processing devices have been provided with a function to create arbitrary characters required by the user, that is, user pattern characters (external character patterns).

However, in the conventional user character creation method, it is necessary to turn on/off each dot, so after creating a user character, if you want to modify or correct a part of it, or reduce it, The operator has to perform on/off operations while looking at the character pattern displayed on a screen such as an LCD and moving the cursor dot by dot, which is disadvantageous in terms of work efficiency.

FIG. 13 is a perspective view showing an example of the appearance of a conventional small-sized Japanese word processor. In the drawings, 1 is a keyboard, 2 is an LCD display device, 3 is a printer, and 4 is a floppy disk.

The keyboard 1 is an input means for inputting character data, control data, etc.

The LCD display device 2 is a display means that visually displays character data and image data in a dot pattern on its screen.

The printer 3 is a dot image printing device such as a dot printer or a thermal dot printer, and prints a dot pattern.

The floppy disk 4 is an external storage device connected to a data processing device having a user character creation function.

FIG. 14 is a diagram showing an example of a custom character creation pattern used in a conventional data processing device having a user character creation function. In the drawings, indicates a cursor.

FIG. 14 shows the case where a pattern of vertical×width=16×16 (dots) is created.

A cursor K is usually blinking on the screen of a pattern for creating a custom character, and the cursor K can be moved to any position within this pattern using the up, down, left, and right keys on the keyboard 1.

In other words, if you move the cursor K to the position where you want to turn on the dot and input the on key, that dot will turn on (
Conversely, if you want to turn it off, press the off key and the dot will turn off (white).

The following Figure 15 is a diagram showing an example of a custom character creation pattern to explain the conventional user character creation method. , ■ to ■ indicate part of the pattern.

For example, the external character rXJ as shown in Fig. 15 (1) has been created, and by modifying a part of this "X" pattern,
Suppose that we want to create a custom character rYJ as shown in FIG. 15(2).

In this case, first move the cursor to the lower half of the external character rXJ in Figure 15 (1), that is, the on position of the dots that make up ■ and ■, and turn off all the dots of ■ and ■. I do.

Next, move the cursor sequentially to the lower half of the external character "Y" in Figure 15 (2), that is, to the dot positions that make up the ■
Perform the operation to turn on all dot positions.

In this manner, in the conventional user character creation method, all dots of a pattern that are no longer needed for correction are turned off, and all dots that are newly required are turned on.

The more complex the private character pattern, the more such operations are required.

Therefore, it takes a lot of effort to correct the external characters, and even if the external characters created in advance are used, the operating efficiency is not improved much.

Therefore, the data processing device having the user character creation function of the present invention has no problem with the above-mentioned disadvantages in conventional data processing devices, that is, since operations are required in units of dots, operations for modifying external characters are difficult. By solving the inconvenience that it takes a lot of effort and does not improve operating efficiency much even if you use pre-created external characters, by adding a line-by-line deletion function and shift function for external character patterns. , the purpose is to improve the processing efficiency of user character creation.

To this end, the present invention provides a data processing device that is equipped with an input device such as a keyboard and a display device such as a CRT or LCD, and has a user character creation function. A key to delete one arbitrary line of a character dot pattern at a time, and a key to shift lines after the deleted line sequentially one line at a time.

A key for specifying the direction of shift is provided, and user characters can be deleted or shifted line by line by inputting the keys in the user character creation mode.

Next, an embodiment of the data processing apparatus having a user character creation function according to the present invention will be described in detail with reference to the drawings.

FIG. 1 is a functional block diagram showing an embodiment of the main structure of a data processing device having a user character creation function according to the present invention. Reference numerals in the drawing are the same as in FIG. 13, and 5 is an input control device, 6 is a custom character control device, 7 is a custom character creation memory, 8 is a character generator, 9 is an output control device, and 10 is a display memory. show.

The functions of each part of the data processing device 1, for example, a Japanese word processor, having a user character creation function shown in FIG. 1 are outlined as follows.

The input control device 5 determines the key information input from the keyboard 1, and notifies the primary character control device 6 when the private character creation key is input.

The external character creation memory 7 stores messages when creating external characters,
The data of the pattern for creating a custom character shown in FIG. 14, a cursor position storage area, a custom character data storage area, etc. are provided.

In the character generator 8, data of various character patterns required by the data processing device are registered in advance.

The external character control device 6 sends a message, data of the pattern shown in FIG. 14, etc. from the external character creation memory 7 to the output control device 9.

When creating a custom character, the output control device 9 causes the message sent from the custom character control device 6 and the data of the pattern shown in FIG. 14 to be output to the LCD display device 2 via the one-display memory 10.

A data processing device having a user character creation function, such as a Japanese word processor or a personal computer, has a configuration as shown in FIG. 1, and its basic configuration is the same as that of a conventional data processing device.

Next, the principle of deletion operation in the user character creation mode in the data processing device having the user character creation function of the present invention will be explained.

FIGS. 2(1) to 2(4) are diagrams showing examples of external character creation patterns for explaining the user character creation deletion function in the data processing apparatus of the present invention. In the drawing, ■～■
indicates the line area of the pattern.

For example, a custom character rXJ as shown in Figure 2 (1) has been created, and you would like to modify part of the pattern of this rXJ to create a custom character rY as shown in Figure 15 (2). do.

In this case, the line area ■ in Figure 2 (1),
If the deletion operation is performed sequentially line by line, as shown in the line area ■ in 2) and the line area ■ in FIG. 2 (3).

As shown in Fig. 2 (4), a pattern in which the lower half of the external character rXJ is deleted can be easily obtained.

After that, for example, the external character “Y” as shown in FIG. 15 (2)
'', that is, to the dot positions that make up ■, and turn on each dot.

The above is a case of simply deleting a line area, but if a movement function, that is, a line-by-line shift function is added to this, the external character creation function can be significantly improved.

The following FIGS. 3(1) to 3(3) are diagrams showing examples of external character creation patterns for explaining the user character creation deletion/movement function in the data processing apparatus of the present invention. In the drawings, ■ to ■ indicate line areas of the pattern. In the drawings, ■ and ■ indicate line areas of the pattern.

For example, suppose that a custom character "X" as shown in FIG. 3(1) has been created, and a part of the pattern of this "X", that is, the entire line area ■, has been deleted.

In this case, after deleting the line below that line,
Move up line by line.

If such processing is performed, a pattern as shown in FIG. 3(2) can be obtained.

Next, if we move the line on the right side of the vertical line area ■ in Figure 3 (2) to the left one line at a time, we can move
An rXJ pattern as shown in 3) is obtained. In addition,
The lowest or oldest line after movement is set to all "0" (off) data.

If we compare the patterns in Figure 3 (1) and (3), we can see that the pattern in Figure 3 (1) has been reduced by the deletion/move operation, resulting in the pattern in Figure 3 (3). I understand.

This indicates that it is also possible to move to any position within the external character pattern area at the same time.

FIGS. 4(1) to 4(3) are diagrams using the user character creation deletion/movement function in the data processing apparatus of the present invention.

FIG. 7 is a diagram illustrating an example of a pattern illustrating movement of a private character pattern to an arbitrary position within a private character pattern area.

In FIG. 4(1), if area A is deleted and moved to the right, the pattern will be placed at a position as shown in FIG. 4(2).

Here, if the pattern of area B is deleted, Fig. 4 (3)
, the pattern will be moved to the bottom right position.

FIGS. 5(1) to 5(7) are flowcharts showing the flow of deletion/shift processing of user character creation in the data processing apparatus of the present invention shown in FIG.

In the drawings, #1 to #27 indicate steps.

The following FIG. 6 is a diagram showing an example of a message when selecting a function for a custom character in the custom character creation mode.

As shown in Figure 6, the external character function is "call".
There are four functions: , "Create/Change", "Copy", and "Overlapping Copy".

Among these four functions, the functions other than the last "overlapping copy" are conventionally used functions.

FIG. 7 is a diagram showing an example of a message when a created custom character is selected in the custom character creation mode.

FIG. 7 shows a case where two created external characters are registered.

FIG. 8 is a diagram showing an example of the case where "Create/Change" is selected in the display state of the message when selecting the external character function shown in FIG. 6.

In order to facilitate understanding, FIG. 8 shows a case where an external character pattern (character font) having an 8×8 (dot) configuration is created.

FIGS. 9 (1) to (3) are diagrams showing an example of a message in the custom character creation mode, where (1) is an example of a custom character pattern, (2) is the content of the memory where the data of the pattern is stored, ( 3) A diagram showing a stack memory indicating the cursor position and the start address of the private character pattern.

In the Japanese word processor shown in Fig. 1, when a custom character key on the keyboard l is pressed, control is changed to
6, the flow of FIG. 5 (1) is assumed to be the star.

Then, in step #1, the message shown in FIG. 6 when selecting the external character function is displayed on one screen, and the user is prompted to select one of the four external character functions.

For example, if you press the key "2" in this display state, the flow will go to step #2 in Figure 5 (1) to determine the power of that key, proceed to step #3, and display the message in Figure 7. and wait for the first key personnel. In this figure 7,
1" to "4" are independent characters, and in order to facilitate understanding, this system is assumed to be able to store four characters.

If it is the cancel key, the flow returns to the start from step #4, and if keys "1" to "4" are input,
Proceed to next step #5.

In step #5, if a key other than keys "1" to r4J is input, an error sound such as a buzzer is emitted in step #6, and the process returns to step #4 to wait for a key input.

In step #5, if any of the keys "1" to "4" is input, the process advances to step #7.

Here, the user changes the first external character rXJ,
Assume that you want to create a new external character.

In this display state, if the key "l", that is, the first non-standard character is selected, the start address of the data corresponding to that number is set.

Next, in step #8, as shown in Fig. 8, the pattern screen for "Creating/changing external characters" and the first external character "X" is displayed. In the case of this Fig. 8, the first and second The first external character shown in the figure has already been registered, and the third and fourth external characters are unregistered.

As shown in Figure 9 (2), the first external character is located at memory addresses 100 to 107, the second external character is located at memory addresses 108 to 115, and the third external character is located at memory addresses 116. It is assumed that the 123rd address and the 4th external character are stored as 8-byte data at addresses 124 to 131 of the memory, respectively.

If you input the key "1" in the previous step #8.

A message as shown in FIG. 8 is output, and the first external character, that is, the data from address 100 in FIG. 9 (2), is displayed on the right edge of the screen.

In step #9, set the cursor address to the initial value (X coordinate is 117 PF, Y coordinate is the upper left corner of the LIOIIC pattern area), and set the data to 200 PF in FIG.
and 201 respectively.

At step #10, the cursor at that position is turned on/off, and at step #11, a key input is waited for.

If the key input is cancelled, it is determined in step #13, the external character mode is exited, and this flow is ended.

If the cancel key is not input in step #13,
Proceed to step #14. For example, input using arrow keys or dot on/off keys.

The same dot creation operation as in the conventional method is performed.

On the other hand, in the previous step #11, "1" to "6"
If the key is human power, move on to the line deletion function.

The line deletion function is performed in the display state shown in FIG.

The flow proceeds from step #11 to #12.

Here, it is assumed that the user changes the external characters of the pattern shown in FIG. 9(1).

The cursor is X7. It is turned on/off at position Y4.

As shown in Figure 9 (2), the memory addresses of this pattern are YO coordinate data at address 100, Yl coordinate data at address 101, ..., Y7 coordinate data at address 107. and each bit is
7. XO corresponds to D6,..., XO corresponds to the DO bit, dot-on (black) is bit data ``'1'', and dot-off (white) is bit data uOn.

In addition, in FIGS. 9(2) and (3), the numbers in brackets on the right side represent the data at each address in hexadecimal notation.

In step #12, the X and Y coordinates of the cursor and the data start address are read.

The cursor is now X7. Since it is located at the Y4 position, the data at address 200 indicating the X coordinate is (07) and 2 indicating the Y coordinate.
The data at address 04 is [04].

Also, since the first address of this external character pattern is address 100, [64] (100=64H) is placed at address 202.
) data is stored.

When deleting lines from this pattern, the user selects keys from rlJ to "6" according to the message shown in FIG.

In step #11 of the flow in Figure 5 (1), key "1"
If you select , the process moves from step #12 to the flow shown in FIG. 5(2).

Then, in step #17, the data start address is read, the bit corresponding to the X coordinate is set to 0'', and the data is rewritten.

In the next step #18, the remaining 7 bytes after the first address are rewritten in the same way, and the process returns to step #11 of the flow shown in FIG. 5(1).

In step #11 of the flow in Figure 5 (1), press the key "2".
If you select , the process moves from step #12 to the flow shown in FIG. 5 (3).

In step #19, read the data at the start address and
Move all bits to the right of the bit corresponding to the coordinate to the left by 1
Shift by bit and DO bit becomes tr Oh
p and rewrite the data.

In the next step #20, the remaining 7 bytes are rewritten in the same way, and the process returns to step #11 in the flow of FIG. 5(1).

In step #11 of the flow in Figure 5 (1), press the key "3"
If you select , the process moves from step #12 to the flow shown in FIG. 5 (4).

In step #21, read the data at the start address and
Set the bit corresponding to the coordinate to '0' and rewrite the data.

In the next step #22, the remaining 7 bytes are rewritten in the same way, and the process returns to step #11 in the flow of FIG. 5(1).

In step #11 of the flow in Figure 5 (1), press the key "4"
If you select , the process moves from step #12 to the flow shown in FIG. 5 (5).

At step #23, the data at the address obtained by adding YJI to the top address is rewritten to #OO2+, and the process returns to step #11 of the flow shown in FIG. 5(1).

In step #11 of the flow in Figure 5 (1), press the key "5"
If you select , the process moves from step #12 to the flow shown in FIG. 5 (6).

In step #24, data (address + 1) is written to the address obtained by adding the X coordinate to the start address.

In the next step #25, similarly, the data is shifted upward one byte at a time, and the byte at the Y7 coordinate is
O'', step #11 of the flow in Figure 5 (1)
Return to

In step 311 of the flow of FIG. 5 (1), key "6" is pressed.
If you select , the process moves from step #12 to the flow shown in FIG. 5 (7).

In step #26, the data (address minus 1) is written to the address obtained by adding the Y coordinate to the start address.

In the next step #27, similarly, the data is shifted downward one byte at a time, and the byte at the YO coordinate is "o".
o” and step #1 of the flow in Figure 5 (1).
Return to 1.

In these cases, when the processing of the l line is completed, the process returns to step #11 of the flow shown in FIG. 5 (1), so after that,
You can then select line processing or perform dot correction.

In order to understand the above-mentioned custom character creation operation, a detailed block diagram of the custom character control device 6 shown in FIG. 1 is shown.

FIG. 10 is a functional block diagram showing the detailed configuration of the external character control device 6 shown in FIG. 1 above. Reference numerals in drawing 6 are the same as in FIG. , 12 is a message data storage memory, 13 is a custom character pattern storage memory, 14 is a copy function control section, 15 is a dot on/off control section, 16 is a cursor coordinate/external character data start address storage memory, 17 is a cursor control section, 1
Reference numeral 8 indicates an on/off timer, and 19 indicates a display data processing section.

Each section in FIG. 10 has a function of performing the processing of the flowchart shown in FIG. 5 (1) to (7) above.

In the above embodiment, the case of 8×8 (dot) font was explained, but 16×16 (dot), 24X
It goes without saying that even in the case of fonts with different numbers of dots, such as 24 (dots), 32×32 (dots) configurations, etc., the same method can be used.

Next, another embodiment of the data processing apparatus of the present invention will be described.

FIG. 11 is a diagram illustrating the operation of creating an external character' by the data processing device having the user character creation function of the present invention. In the drawings, ■ to ■ and ■' to ■' indicate external character patterns.

First, on the message display screen shown in FIG. 6, use the "copy" function to register external characters such as ■ in FIG. 11.

For this custom character pattern, use the line deletion function,
As shown in ■' in FIG. 11, the external character "Win" is converted into a pattern containing only "Hen".

Next, register the external character "Fuku" like ■ in FIG. 11.

For this custom character pattern, use the line deletion function,
As shown in ■' in Figure 11, the ``tsukuri'' of the external character ``fuku''
Convert to just a pattern.

After that, the patterns of ■' and ■' in Fig. 11 are combined using the "superimposed copy" function, and the external characters like ■ in Fig. 11 [
Create a “radius”.

In this state, there will be a gap between "rhen" and "tsukuri", so if you use the line deletion function to fill in the space between the rain patterns, you will get a clean external character "輻" like ■' in Figure 11.
is completed.

As described above, even in a system equipped with only JIS first level kanji fonts, the data processing device having the user character creation function of the present invention can easily create most of the second level kanji. This makes it possible to significantly reduce font memory.

If such custom character creation processing is performed using the conventional dot-by-dot processing method, it takes an extremely large amount of time and effort, and the quality cannot be very high.

FIGS. 12 (1) and (2) show the correspondence between the external character "輻" produced by the conventional data processing device with the user character creation function and the external character "輻" produced by the data processing device with the user character creation function of the present invention. In the figure showing (1), in the conventional case, (
2) shows the case of this invention.

If the external character "輻" is created using the conventional dot-by-dot processing method, a very fleshy pattern cannot be obtained, as shown in FIG. 12 (1).

If one were to create a pattern with a lot of extra weight, as shown in FIG. 12 (2), it would be necessary to perform on/off operations for each dot, which would require a great deal of effort.

However, according to the data processing device of the present invention.

You can easily obtain a full-bodied external character "radius" pattern using the "copy" and "overlapping copy" functions, and if there is an unnecessary gap between the two, you can easily close it using the line deletion function. be able to.

On the other hand, in the conventional dot-by-dot processing method, for example, as in ``■'' and ``■'' in FIG.
In order to create a pattern, each dot must be deleted one by one, which is very tedious and extremely difficult to create a high-quality pattern.

As explained in detail above, in this invention.

In a data processing device that is equipped with an input device such as a keyboard, a display device such as a CRT or LCD, and has a user character creation function, an arbitrary line of a dot pattern of a user character is displayed on the input device in a user character creation mode. 1 minute
It is equipped with a key for deleting lines at a time, a key for sequentially shifting lines after the deleted line by I lines, and a key for specifying the shifting direction. I am trying to delete and shift.

Effects Therefore, according to the data processing device having the user character creation function of the present invention, it is possible to turn off dots for each line of the custom character pattern, so that the operational efficiency of the work of changing the custom characters is significantly improved.

In addition, the line deletion function minimizes the deterioration in character quality, thereby producing many excellent effects such as greatly simplifying the work of creating reduced characters and composite characters.
