Description

DETAILED DESCRIPTION OF THE INVENTION TECHNICAL FIELD The present invention relates to electronic equipment, and more particularly to an electronic equipment capable of outputting cursive characters.

2. Description of the Related Art Typewriters and other electronic devices capable of outputting characters, figures, etc. have been known for some time.

The output patterns of these electronic devices are generally printed characters, and this is sufficient for transmitting textual information.

However, in the future, as there is a demand for increased expressiveness of output characters, it is expected that electronic devices capable of outputting cursive characters in which characters are connected will become commonplace.

For example, when you want to insert handwritten characters into text information in printed text, when a person who is not good at handwriting wants to create various documents, when the printed text feels cold, and when you want to add your own signature. In order to output beautiful handwritten characters, electronic devices such as cursive typewriters and printers are required.

To output such cursive characters, a cursive character pattern and an interpolation pattern that connects these character patterns are required, and a continuous cursive character pattern can only be formed by using the interpolation pattern.

If display can be performed, the learning effect of cursive characters will be significantly improved.

Purpose The present invention can meet the above demands, and provides an electronic device configured to output cursive characters and interpolation patterns in reverse order by pressing a cursive key. is intended to provide.

EXAMPLE The present invention will be described in detail below using an English typewriter type electronic device as an example.

Figure 1 and the following diagrams explain one embodiment of the present invention.
A block diagram of the control circuit is shown in the figure.

In the St diagram, what is indicated by the symbol 1 is the central processing unit (c
pu), which has a display device (DIS) as an output device.
2 and a printer (PTR) 3 are connected.

What is indicated by code 4 is a character generator (CG),
The symbol 5 is a pattern generator, and these are C
Connected to PU 1. These generate a pattern when given a predetermined address.

In addition, the CPU i has lacidum access memory (RAM).
)6 is connected.

RAM 13 has an address section R1, a non-interpolation flag section R2,
It consists of an identification code section R3 and a point section R4.

Details of each part of the RAM e will be described later.

On the other hand, numerals 1 to 8 represent a group of input keys connected to the CPU 1. Kl is the print/cursive mode conversion key, K
2 is the one-stroke writing mode conversion key, K3 is the erase key, K4 is the right cursor key, K5 is the cursor key, K6 is a group of alphabet letters, Kl is ? l'l'1; Symbol key such as 1; K8 is a cursor erase key for interpolation patterns.

Assuming that the mode of the electronic device is currently in print mode based on the above configuration, pressing 1 on the print/cursive mode conversion key will change the electronic device to cursive mode, and then Press to switch back to print mode. Printing examples of rENJOY J in print mode and cursive mode are shown in FIGS. 2(A) and 2(B). Next, add 8 to the group of letters of the alphabet as ``rENJOY'' and see Figure 2 (B).
The control operations up to printing cursive characters as shown in FIG. 1 will be explained.

In the present invention, a cursive character string as shown in FIG. 2(B) can be decomposed into a character pattern as shown in FIG. 3(A) and an interpolation pattern as shown in FIG. 3(B). be.

rENJOY J is composed of a total of 9 types of pattern combinations, 5 character patterns and 4 interpolation patterns, as shown in FIGS. 3(A) and 3(B).

Therefore, if rENJOY J and key human power are used, the third
By generating an interpolation pattern as shown in Figure (B) and connecting adjacent characters, a cursive character string can be generated.

To determine these interpolation patterns, it is sufficient to determine the positions of the pen-up point PU of the immediately preceding character and the pen-up point PD of the next character to be printed, and connect them with a straight line or curve.

Therefore, in the present invention, the processing code of one character is expressed in 16 bits, for example, as shown in FIG. 3(C), and the first 1 bit indicates that the character symbol pattern corresponding to this processing code requires an interpolation pattern. This is a flag indicating whether or not to do so. If it is necessary, it is set to "0", and if it is not necessary, it is set to "1". In addition,? or! Symbol patterns such as , etc. do not require interpolation patterns.

The 7 bits following this interpolation flag are codes for identifying character symbols, and the character generator 4 uses these 7 bits to identify characters and symbols.
Bit address information generates a corresponding pattern of characters or symbols.

The last 8 bits are information for the interpolation pattern, of which the upper 4 bits are the pen-down position of the cursive character pattern to be printed, and the lower 4 bits are the pen-up position.

For example, the pen-down position and pen-up position are as shown in Figure 4 (
Positioning is performed as shown in A).

In other words, a certain character, for example reJ, has 16 pen-down points on the left and 1 pen-up point on the right.
Six points are determined in advance, and the pen-down point and pen-up point that the character should take are determined according to these points.

Now, according to ASCII-C0DE, the identification code of the letter "e" is 45, the pen down point is "A", the pen up point is "3", and the letter re
"'s 16-bit code is expressed in BCD code as r
It becomes 45A3J. With such a configuration, 18×1fl=256 types of interpolation patterns are required, and as shown in FIG. It is stored in 5.

Incidentally, in the case of this embodiment, a configuration is adopted in which the processing code corresponding to the input key is once stored in the RAM 6 and then printed or displayed.

This is so that the cursive characters can be edited later. Using the above interpolation pattern, now r
ENJOY! FIG. 5 shows the storage situation in RAM El when J is input. That is, addresses 0 to 5 are used to store the code of each character in cursive, as well as pen-down and pen-up points.

Note that since "!" does not require an interpolation pattern, the interpolation flag C/S is rlJ.

The device is now in cursive mode, and in this state,
When you press the "E" key, the r 45 corresponding to this key is pressed.
A code A5J is generated, stored in RAM 8, and the address information of "45" is sent to character generator 4.
A character pattern is generated by applying
) is printed or displayed on the display.

As is clear from FIG. 6(A), this character is displayed with an interpolation pattern already attached.

When the rNJ key is subsequently pressed, the code "r4Eold" is generated and similarly stored in the RAM El.

At this time, CPU 1 confirms that the non-interpolation flag of rnJ is "0", and then prints "5", which is the pen-up point information of the character "e", which is the previous character, and the pen-down point of the character rnJ. Interpolation pattern information "5B" is generated based on the point information rBJ, and the pattern generator 5
An interpolation pattern is generated by inputting "5B" as address information into the
) is printed (displayed) following the previous character.

Thereafter, the character identification code "4E" is given to the character generator 4 as address information to generate a character pattern, and the characters rnJ are printed (displayed) as shown in FIG. 6(C). Similarly, rJJ, rO
Processing for each key human power of J, rYJ is performed,
Printed (displayed).

On the other hand, if you press the last character "!", the code r 21
00J and this code is stored in RAM Ill. FIG. 5 shows the storage state of the RAM fl at this time.

CPU t detects that the interpolation flag is "1", knows that the interpolation pattern is unnecessary, skips spaces by that pattern, and immediately creates the pattern corresponding to the character code "21" in the character generator. 4, and print is performed.

This state is the state shown in FIG. 6(D).

In this way, cursive characters are printed (displayed) while determining whether or not an interpolation pattern is necessary using the processing code.
It becomes possible to do so. By the way, the method of displaying characters and symbols in the present invention is accompanied by a cursor display as shown in FIG.

That is, when you press the key rENJOY J, a segment pattern for cursor display is prepared directly below each character pattern and interpolation pattern.

The cursor pattern consists of a long cursor (LC) pattern for characters directly below the character pattern and a short cursor (SC) pattern for the interpolation pattern directly below the interpolation pattern, which are consecutively arranged.

In the state shown in Figure 7, the current cursors are the short cursor SC immediately after the character "y" and the long cursor L.
C is ON, prompting you to input the next character.

In addition, if you press 5 on the left cursor key three times in the state shown in Figure 7, the cursor will advance 3 points to the left, and the long cursor LC directly below "j" and the short cursor SC on both sides of 7, a total of 3 points. is ON.

This state is shown in FIG. 9(A).

For example, rj
This is to indicate the range of patterns that will be affected by the operation when editing, such as erasing, inserting, or rewriting the letter J.

Regarding the practical internal operation of such a display method, Part 11
The explanation will be as follows with reference to the flowchart shown in the figure.

That is, in the initial state, the display 2 is cleared and is in a non-display state. As shown in Figure 8 (A), only the long cursor at the first character digit position is O.
It is N. Further, RAM 8 has been completely cleared, and "O" has been written therein. At this time, the interpolation flag is in a state where "1" is stored for the previous address. This state is shown in FIG. 8(C).

In this state, if there is a key human power "E", then C
PU uses processing code r 45A5J in step sl.
and RAM 6 c7) Kerf At pointer CP
In step S2), the cursor pointer CP moves to the next address position. This state is shown in FIG. 8(D).

Furthermore, the CPU 1 sends address information to the character generator 4 at the current cursor position to the display 2.
45'', reJ displays the pattern as shown in FIG. 8(B) (step S3.S
4). At the same time as this operation, the cursor pointer CP changes to C22.
(step S5).

Then, as shown in FIG. 8(A), the currently displayed cursor is turned off, and the next long cursor is turned on as shown in FIG. 8(B) (step S8,
S7).

Then, turn on the short cursor sc on both sides of the long cursor LC shown in FIG. 8(B), which is currently on,
8(D) in step s8 to turn it off.
RAM 8 indicated by the current cursor pointer CP' shown in
Read the interpolation flag C/S of the address immediately before the address. Then, the process advances to step S8, and the interpolation flag C/S is set to "1".
'', the short cursor SC immediately before the currently lit long cursor is turned OFF in step SIO, and if the interpolation flag is rOJ, the short cursor SC is turned ON (step 5ll). Then, in step S12, the interpolation flag of the address immediately after the RAM address indicated by the cursor pointer CP' is read out, and if this interpolation flag is "1" in step SI3, the process advances to step S15, and the interpolation flag immediately after the currently lit long cursor is read out. The short cursor is turned off, and if it is "0", the short cursor is turned on in step S14. Note that if 5 is pressed on the left cursor key, the cursor is moved by the number of keys pressed in step 816 and the processes from step S6 onwards are performed, and when 4 is pressed on the right cursor key, the steps from step 85 onwards are performed. Process.

By controlling the short cursor for interpolation patterns and the long cursor for character patterns in this way, it is possible to clearly express the range of influence that the pattern output on the display corresponding to the next key input has on the current display state.

By the way, in the above example, in order to erase the character pattern "j", move the cursor below the character as shown in Figure 9 (A) and press 3 on the erase key. The state shown in (B) is reached. In the case of Figure 9 (A), the long cursor and the short cursors on its left and right are ON, and this is clear from the RAM address in Figure 10 (A), where the left short cursor is ON. Interpolation pattern>9- This indicates that the processing code is for character pattern "4A" corresponding to the long cursor and interpolation pattern "8B" corresponding to the short cursor on the right side.

When 3 is pressed on the erase key in this state, the RAM address corresponding to the current cursor pointer CP is erased in step S1 as shown in the flowchart of FIG.

Then, in step S2, the processing code at the address below the erased address is rewritten, and in step S3, the pen-up point information of rnJ and the pen-down point information of the character "0" are read out anew. Then, in step S4, a new interpolation pattern is generated by the pattern generator, and in step S5, the following consecutive character patterns are output.

Erase operations can be performed in this manner.

By the way, if you want to erase only the interpolation pattern, if you press 8 on the interpolation pattern erase key, only the interpolation pattern corresponding to the short cursor that is currently ON will be erased.

At this time, the contents of the RAM 8 are saved and the position of the cursor pointer CP does not change.

Erasing only the interpolation pattern in this way is useful when learning cursive characters, when you want to separate consecutive character patterns and check each cursive character, when you want to change the interpolation pattern, or when you want to change the interpolation pattern. etc. 1
This is very effective when you want to separate each character or when character information is difficult to distinguish because the characters are continuous.

By the way, the -brush writing key 2 will be explained below.

In the present invention, the character generator 4 and the pattern generator 5 are generators that sequentially generate dot position information (Dl, ND) that lights up in order to display both character patterns and interpolation patterns in one stroke when predetermined address information is obtained. It is composed as follows.

The contents are shown in FIG.

That is, as shown in FIG. 12, DIND information of each pattern is stored in order from address 1 as dot position information from 1st to nth dots DIND 1 ''[lIN[ln.

Based on this structure, in order to display cursive writing, press rENJOY J in cursive mode in advance, and check the processing code in RAM 8 as shown in Figure 10 (A). .

FIG. 13 shows the control operation when 2 is pressed on the one-stroke writing key in this state.

That is, the addresses ADRI and ADR2 pointed to by the address pointer of RAM B in steps Sl and S2
Clear.

The process then proceeds to step S3, where the address section reads the code information of ADRI in RAM &. And step S4
-A to detect the end of the character to be written.
Determine whether the DRI code is “0” or less, and
”, the process ends, and if it is not “0”, the process proceeds to step S5, where the code information is inputted to the character generator 4 as address information, thereby lighting up the “e” pattern one dot at a time. To go.

Next, the process proceeds to step S6, where the address ADR2 is increased by +1, and the 4th bit of pen-up information in the RAM of ADRI is used as the upper bit, and the 8 bits are set as the HP code information, with the 4th bit of pen-down information in the RAM of ADR2 as the lower bit. (Step S?).

Next, the process advances to step S8, where the display digit is moved to one stacked stone, and the HP information is transferred to step S8 in order to display the interpolation pattern.
Pattern generator 5 as address information in 8.
, and the interpolation pattern will be displayed sequentially on the currently displayed digit.

Then, in step S10, ADR1 is increased by +1 and the process returns to step S3.

By repeating the above-described operations, it becomes possible to display a certain character string in one stroke, and learning the order of strokes becomes possible.

Since this embodiment is configured as described above, it has a cursive character generator and an interpolation pattern pattern generator, and by providing a cursive output mode key, it can output not only printed characters but also characters. It is possible to print or display cursive characters with continuous spaces.

Furthermore, it is possible to output cursive characters and interpolation patterns in the reverse stroke order by pressing the cursive writing key.
A stroke order learning function can be provided.

In the above embodiment, only an English typewriter was described, but it can also be applied to cursive writing of other Japanese languages such as Japanese kana characters and kanji, and is highly effective in learning stroke order. can demonstrate.

Effects As is clear from the above explanation, according to the present invention, it is possible to output cursive character patterns and interpolation patterns in the reverse stroke order by pressing the stroke key, which has a great effect on stroke order learning. be able to.
