Description

TECHNICAL FIELD The present invention relates to an electronic device, and more particularly to an electronic device capable of outputting cursive characters.

2. Description of the Related Art Conventionally, typewriters and other electronic devices capable of outputting characters and figures have been known.

The output patterns in these electronic devices are generally characters in print type, and this was sufficient for transmitting character information.

However, it is presumed that electronic devices that can output cursive characters connecting between characters will become common in the future as demand for increasing the expressiveness of the output characters.

For example, when you want to insert a draft character in the character information in typeface, when you want to create various documents by people who are not good at handwriting, or when you feel cold in typeface, and when you want to sign yourself. In order to output beautiful handwritten characters, electronic devices such as a cursive typewriter and a printer are required.

In order to form such a cursive character, a cursive character pattern and an interpolating pattern that makes the character patterns continuous are necessary, and continuous cursive character output can be realized only by using the interpolation pattern.

However, due to the appearance of letters such as lowercase letters after some uppercase letters, if there is no interpolation pattern and the readability is improved, or if the user learns a specific character in a written sentence or uses a pattern recognition device. In order to improve the recognition rate or the like, it may be desired to erase the interpolation pattern and simplify the output pattern.

In such a case, it is convenient if only the interpolation pattern can be erased.

An object of the present invention is to meet the above demands, and to provide an electronic device in which cursive characters can be easily read by erasing only an arbitrary interpolation pattern. Has an aim.

Example Hereinafter, the present invention will be described in detail by taking an electronic device of an English typewriter format as an example.

FIG. 1 and the following figures illustrate an embodiment of the present invention.
The figure shows a block diagram of the control circuit.

In FIG. 1, reference numeral 1 indicates a central processing unit (C
PU), which has an indicator (DIS) 2 as an output device.
And a printer (PTR) 3 are connected.

Reference numeral 4 indicates a character generator (CG),
Reference numeral 5 is a pattern generator (PG) connected to these CPUs 1. These generate a pattern corresponding to a given address.

Further, the CPU 1 has a random access memory (RAM).
6 is connected.

The RAM 6 has an address section (R1) and a non-interpolation flag section (R
2), an identification code part (R3) and a point part (R4).

Details of each unit of the RAM 6 will be described later.

On the other hand, reference characters K1 to K8 are a group of input keys connected to the CPU 1. K1 is a type / writing mode conversion key, K2
Is a one-stroke writing mode conversion key, K3 is an erase key, K4 is a right cursor key, K5 is a left cursor key, K6 is an alphabetic character key group, and K7 is? 、! 、! ,,,;, and the like, and K8 is an interpolation pattern cursor deletion key.

With the above configuration, assuming that the mode of the electronic device is now in the print mode, pressing the print / cursive mode conversion key K1 causes the electronic device to be in the write mode, and further pressing K1. And it becomes print mode again. Printing examples of "ENJOY" in the typeface mode and the writing mode are shown in FIGS. 2 (A) and 2 (B).

Next, the control operation until the alphabetic character key group K6 is operated as "ENJOY" to print cursive characters as shown in FIG. 2B will be described.

In the present invention, a character example of a cursive body as shown in FIG. 2 (B) is decomposed into a character pattern as shown in FIG. 3 (A) and an interpolation pattern as shown in FIG. 3 (B). is there.

“ENJOY” is 5 as shown in FIGS. 3 (A) and 3 (B).
It is composed of a combination of 9 character patterns and a total of 9 patterns of 4 interpolation patterns.

Therefore, when the keystroke "ENJOY" is entered, the cursive character string can be generated by generating an interpolation pattern as shown in FIG. 3B and connecting adjacent characters.

To determine these interpolation patterns, the positions of the pen-up point PU of the immediately preceding character and the pen-down point PD of the character to be printed subsequently may be determined, and the two may be connected by a straight line or a curved line.

Therefore, in the present invention, the processing code of one character is expressed by, for example, 16 bits as shown in FIG. 3C, and the leading 1 bit requires a character symbol pattern corresponding to this processing code to be an interpolation pattern. It is a non-interpolation flag indicating whether or not to perform it. When it is necessary, "0" is set, and when it is not necessary, "1" is set. What? Ya! Interpolation patterns are not required for symbol patterns such as.

The wabbit following the non-interpolation flag is an identification code for identifying a character and symbol, and the character generator 4 generates a corresponding character or symbol pattern based on the 7-bit address information. The last 8 bits are information for the interpolation pattern, of which the upper 4 bits are the pen down point PD of the pattern of the cursive character to be printed and the lower 4 bits are the pen up point PU.

The pen down point PD and the pen up point PU are positioned as shown in FIG. 4 (A), for example.

That is, 16 points of pen down points PD are determined on the left side of a character, for example, "e", and 16 points of pen up points PU are determined on the right side, and the pen down points PD and pen up points PU which the character should take according to these points are determined. Is decided.

According to ASC II-CODE, the character "e" has an identification code of 45, the pen down point PD is "A", and the pen up point PU is "5". The processing code of is expressed as a BCD code, which is “45A5”. With such a configuration, 16 × 16 = 256 kinds of interpolation patterns are required, and as shown in FIG.
Interpolation patterns corresponding to the interpolation pattern information up to F ”are prepared, and these are stored in the pattern generator 5.

By the way, in the case of this embodiment, the processing code corresponding to the input key is stored in the RAM 6 once and then printed or displayed.

This is so that the cursive characters can be edited later. Now using the above interpolation pattern,
FIG. 5 shows the storage status in the RAM 6 when "ENJOY!" Is input. That is, the non-interpolation flag, the identification code, the pen down point PD, and the pen up point PU of each character of the cursive are stored using addresses 0 to 5.

Since "!" Does not require an interpolation pattern, the non-interpolation flag (C / S) is "1".

Now the device is in cursive mode and in this state,
When the "E" key is pressed, "45" corresponding to this key is pressed.
A processing code "A5" is generated and stored in the RAM 6, and a character pattern is generated by applying the identification code "45" to the character generator 4 as address information, which is printed or printed as shown in FIG. 6 (A). Displayed on the display.

Then, when the "N" key is pressed, the processing code "4EB
1 ”is generated and similarly stored in the RAM 6.

At this time, the CPU 1 confirms that the non-interpolation flag of "n" is "0" and then "5", which is the information of the pen-up point PU of the character "e" which is the immediately preceding character, and "n".
Interpolation pattern information "5B" is generated by the information "B" of the pen down point P of the character, and the interpolation pattern is generated by inputting "5B" to the pattern generator 5 as address information. As shown in FIG. 6 (B), it is printed (displayed) following the previous character.

Thereafter, the identification code "4E" is given to the character generator 4 as address information to generate a character pattern, and the character "n" is printed (displayed) as shown in FIG. 6 (C). Similarly, "J", "O",
The processing for each key input of "Y" is performed and printed (displayed).

On the other hand, when the last character “!” Is pressed, the processing code “21
00 ”and this code is stored in RAM 6.
The storage state of the RAM 6 at this time is shown in FIG.

The CPU 1 detects that the non-interpolation flag is "1", knows that the interpolation pattern is unnecessary, skips the space for the pattern, and immediately outputs the identification code "21".
A pattern corresponding to is generated by the character generator 4 and printing is performed.

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

In this way, cursive characters can be printed (displayed) while determining whether or not an interpolation pattern is required by the non-interpolation flag. By the way, the method of displaying characters and symbols in the present invention is accompanied by cursor display as shown in FIG.

That is, when "ENJOY" is keyed in, a segment pattern for cursor display is prepared directly below each character pattern and interpolation pattern.

The cursor pattern has a configuration in which a long cursor (LC) pattern for characters that is directly below the character pattern and a short cursor (SC) pattern for interpolation patterns that is directly below the interpolation pattern are continuously arranged.

In the state shown in FIG. 7, the current cursor is the short cursor SC immediately after the character "y" and the long cursor LC.
And are on, prompting you to enter the next character.

When the left cursor key K5 is pressed three times in the state shown in FIG. 7, the cursor moves to the left by 3 points, and the long cursor LC directly under "j" and the short cursors SC on both sides thereof are turned ON in total. Has become.

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

This kind of cursor display is performed, for example,
This is because when the character portion of "j" is erased, inserted, or rewritten, etc., the range of the pattern affected by the operation is designated.

About the realistic internal operation of such a display method
It will be as follows when it explains with the flowchart figure of a figure.

That is, in the initial state, the display device 2 is cleared and is in the non-display state. Then, as shown in FIG. 8 (A), only the long cursor LC at the leading character digit position is ON. Further, the RAM 6 is all cleared, and "0" is written in the area where the identification code, the pen down point PD and the pen up point PU are stored. At this time, "1" is stored in the area in which the non-interpolation flag is stored. This state is shown in FIG. 8 (C).
Shown in.

If there is a key input of "E" in this state, C
PU1 processes code "45A5" in step S1.
Is generated and stored in the address position pointed to by the cursor pointer CP of the RAM 6 (step S2), and the cursor pointer CP moves to the next address position. This state is shown in FIG.

Further, the CPU 1 sets the address information “4” for the character generator 4 at the current cursor position for the display unit 2.
By inputting "5", the pattern of "e" is displayed as shown in FIG. 8 (B) (steps S3, S).
4). At the same time as this operation, the cursor pointer CP changes to CP '.
Moves to the position (step S5).

Then, as shown in FIG. 8 (A), the currently displayed long cursor LC is turned off, and FIG. 8 (B) is displayed.
As shown in, the next long cursor LC is turned on (steps S6 and S7).

Then, the short cursors SC on both sides of the long cursor LC shown in FIG.
In order to turn it off in step S8, FIG.
The non-interpolation flag C / S of the address immediately before the address of the RAM 6 indicated by the current cursor pointer CP 'shown in is read. When the non-interpolation flag C / S is determined to be "1" in step S9, the short cursor SC immediately before the currently illuminated long cursor LC is turned off in step S10, and the non-interpolation flag is "1". If it is "0", the short cursor SC is turned on (step S11).
And

Then, the non-interpolation flag of the address immediately after the address of the RAM 6 indicated by the cursor pointer CP 'is set in step S12.
In step S13, if the non-interpolation flag is "1", the process proceeds to step S15, and the short cursor SC immediately after the currently lit long cursor LC is turned OFF. If "0", the short cursor SC is obtained in step S14. Turn on SC. When the left cursor key K5 is pressed, the cursor is moved by the number of times pressed in step S16, and the processing of step S and subsequent steps is performed. When the right cursor key K4 is pressed, the processing of step S5 and subsequent steps are performed. Do.

In this way, by controlling the short cursor SC for the interpolation pattern and the long cursor LC for the character pattern, it is possible to clearly express the range in which the pattern output on the display corresponding to the next key input affects the current display state. it can.

By the way, in order to erase the character pattern "j" in the above-mentioned example, when the cursor is moved to the bottom of the character and the delete key K3 is pressed, as shown in FIG. The state shown in B) is obtained. In the case of FIG. 9A, the long cursor LC and the left and right short cursors SC are ON, which means that
As is clear from the address of RAM 6 in FIG.
The short cursor SC on the left is the interpolation pattern "1",
It indicates that the processing code is "2" and the character pattern "4A" corresponding to the long cursor LC and the interpolation pattern "8B" corresponding to the right short cursor SC.

When the delete key K3 is pressed in this state, the process code stored in the address position of the RAM 6 corresponding to the current cursor pointer CP is deleted in step S1 as shown in the flow of FIG. Then, the processing code stored in the address position subsequent to the erased address position is rewritten in step S2, and step S3
Newly, the information of the pen-up point PU of "n" and the information of the pen-down point PD of the character of "0" are read. Then, in step S4, a new interpolation pattern is generated by the pattern generator 5, and step S5
At, the following consecutive character patterns are output.

In this way, the erase operation can be performed.

By the way, when the interpolation pattern erasing key K8 is pressed when only the interpolation pattern is to be erased, only the interpolation pattern corresponding to the short cursor SC which is currently ON is erased.

At this time, the contents of the RAM 6 are saved and the position of the cursor pointer CP does not change.

The erase operation of only the interpolation pattern will be described in detail below. Now, assuming that the contents of FIG. 9 (A) are displayed on the display unit 2, the cursor pointer CP indicates the position of ADR = 0002 as shown by the arrow in FIG. In this state, when the interpolation pattern erasing key K8 is pressed to erase the interpolation pattern, ADR = 0002 and the next ADR = 00 shown in FIG.
The non-interpolation flags (C / S) of 03 are set to 1, respectively. Then, the above-described steps S8 to S1 in FIG.
The same process as the process of 5 is performed. That is, ADR = 00
02 and ADR = 0003 non-interpolation flag (C / S)
Since each of the short cursors is 1, the short cursors SC on the left and right sides of the long cursor LC under “j” shown in FIG. 9A are erased. Along with this, the interpolation patterns on the left and right sides of the “j” are erased (converted to spaces).

Erasing only the interpolation pattern in this way is useful for learning cursive characters when you want to check each cursive character by separating continuous character patterns, change the interpolation pattern, and perform pattern recognition. This is very effective when it is difficult to distinguish the character information because it is difficult to distinguish the character information because it is desired to separate one character at a time.

The one-stroke writing key K2 will be described below.

In the present invention, the character generator 4 and the pattern generator 5 are configured as generators that sequentially generate dot position information (DIND) that lights up both the character pattern and the interpolation pattern in the order in which they are displayed with a single stroke when given address information. There is.

The contents are shown in FIG.

That is, as shown in FIG. 12, the DIND information of each pattern is stored in order from the first address (ADR) as dot position information of DIND _{1 to} DIND _n from the _{1st to nth} dots.

For example, when the pattern of e is the dot pattern shown in FIG. 15 (A), the dot position information shown in FIG. 12 is as follows. That is, DIND ₁ is 18, DIN
D ₂ is 28, DIND ₃ is 38, ..., And DIND ₄₂ is B5. When the pattern of n is as shown in FIG. 15 (B), the dot position information is as follows. That is,
DIND ₁ is 0B, DIND ₂ is 1C, ..... DIND
₄₀ becomes B1. Here, 0-B on the upper side of the dot pattern
0 to F on the left side and the left side respectively indicate the positions of the dots.

Based on such a structure, in order to display one-stroke writing, "ENJOY" is key-inputted in advance in the writing pair mode, and the processing code is confirmed in the RAM 6 as shown in FIG. 10 (A).

FIG. 13 shows the control operation when the one-stroke writing key K2 is pressed in this state.

That is, in steps S1 and S2, the address positions ADR1 and ADR indicated by the address pointer of the RAM 6 are indicated.
DR2 (address position where information of pen down point PD and pen up point PU is stored respectively) is cleared.

Then, the process proceeds to step S3, where the address portion is A of the RAM 6
Read the processing code of DR1. Then, in step S4, the AD is detected to detect the end of the character to be written with one stroke.
It is determined whether the identification code of R1 is "0",
If it is "0", the process is terminated, and if it is not "0", the process proceeds to step S5, and the identification code is input to the character generator 4 as address information, whereby 1
The "e" pattern is lit up dot by dot.

That is, the dot position information DIN shown in FIG.
Using D ₁ , DIND ₂ , ..., FIG.
(D) Further, as shown in FIG. 15 (A), "e"
The pattern is displayed. FIG. 16 (A) shows the first dot, (B) shows the second dot, (C) shows the tenth dot,
(D) shows the display up to the 29th dot. Then, FIG. 15A shows the display up to the last dot. In this manner, the pattern "e" is sequentially displayed dot by dot in the writing order.

Succeedingly, in a step S6, the address ADR2 is incremented by +1 and 4 bits of information of the Benuppont PU of the RAM of ADR1 is set as an upper bit and 4 bits of information of the pen down point PD of the RAM of ADR2 is set as a lower bit. As HP code information (step S7).

Then, in step S8, the display digit is moved to the right by one digit, and the HP code information for displaying the interpolation pattern is input to the pattern generator 5 as address information in step S9, and the interpolation pattern is displayed in the currently displayed digit. Are sequentially lit and displayed.

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

By repeating the above-mentioned operation, it is possible to display a certain character string with one stroke, and the stroke order can be learned.

Since the present embodiment is configured as described above, it has a cursive character generator and a pattern generator for an interpolation pattern, and by providing a cursive output mode key, not only the character output of the typeface but also the character It is possible to print or output a cursive script with continuous intervals.

In addition, in the above-mentioned embodiment, the description is limited to the English typewriter, but it can be applied to cursives of other national languages such as Japanese kana and kanji, and can exert an excellent effect. it can.

In addition, when outputting cursive characters such as kana and kanji, not only horizontal writing but also vertical writing can be performed.

Effect As is apparent from the above description, according to the present invention, since a configuration that can delete only an arbitrary interpolation pattern that makes the cursive characters continuous, the cursive characters are separated one by one. Therefore, it is possible to make them surely legible.
