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 the demand for increased expressiveness of output characters increases, it is expected that electronic devices capable of outputting cursive characters in which characters are connected will become more common.

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 form such cursive characters, a cursive character pattern and an interpolation pattern that makes the character patterns continuous are required, and only by using the interpolation pattern can continuous cursive characters be output.

However, if the interpolation pattern is complex, it may be difficult to identify the output pattern of a single character, making it difficult to accurately transmit a series of character information.

In such a case, if only the interpolation pattern can be erased, the cursive characters can be read.

Purpose The present invention was made in response to the above-mentioned demands, and an object of the present invention is to provide an electronic device that makes it possible to easily read cursive characters by erasing only the interpolation pattern. It is said that

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 FIG. 1, what is indicated by the symbol l is the central processing unit (c
pu), which has a display (01S) as an output device.
2 and a printer (PTR) 3 are connected.

The one indicated by code 4 is a character generator (COG)
, 5 is a pattern generator, which is connected to the CPU 1. These generate a pattern when given a predetermined address.

In addition, CPt11 includes random access memory (RAM).
) 8 is connected.

RAM El 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 6 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 ? +'+9+; Symbol key such as 2, K8 is a cursor erase key for interpolation pattern.

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 6 to the alphabet/atom key group by typing "r ENJOY", as shown in Figure 2 (
The control operation up to printing cursive characters as shown in B) 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
An interpolation pattern as shown in figure (B) is generated, and the adjacent -
"By connecting the letters, you can generate a cursive character string.

In order 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 about 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 example has 16 pen down points on the left side of reJ and 1 pen up point on the right side.
Six points are determined, and the pen-down point and pen-up point that the character should take are determined according to these points.

Now, according to ASCn-'C0DE, the identification code of the letter "e" is 45, the pen down point is rAJ, the pen up point is "3", and the letter "e" is
'' is expressed in BCII code as r45A3J. With such a configuration, one type of interpolation pattern of 113X IEl = 25 is required, and as shown in Figure 4 (B), from "00" to "FF"
Interpolation patterns corresponding to the addresses up to are prepared, and these are stored in the pattern generator 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 B 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 r45A corresponding to this key
A code 5J is generated, stored in RAM 8, and "
45'' to the character generator 4, a character pattern is generated and printed or displayed on a display as shown in FIG. 6 (AI).

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

Then, when the "N" key is pressed, the code r4EBIJ
is generated and similarly stored in RAM 8.

At this time, CPU 1 confirms that the non-interpolation flag of "n" is "0", and then prints "5", which is the pen-up point information of the character reJ, which is the immediately preceding character, and the pen-down point of the character rnJ. Interpolation pattern information r5BJ is generated based on the point information "B", and an interpolation pattern is generated by inputting "5B" to the pattern generator 5 as address information, and this interpolation pattern is shown in FIG.
The character is printed (displayed) following the previous character as shown in B).

Thereafter, the character identification code "4E" is given to the character generator 4 as address information to generate a character pattern, and the character rn4 is printed (displayed) as shown in FIG. 6(C). Similarly, rJ'', rOJ
, rYJ are processed manually and printed (displayed).

On the other hand, if you press the last character "!", the code r210
0J and this code is stored in RAM B.

The storage state of the RAM 8 at this time is shown in FIG.

CPU 1 detects that the interpolation flag is "1" and knows that the interpolation pattern is unnecessary, skips spaces by that pattern and immediately writes character codes r2+, +
A pattern corresponding to the pattern is generated by the character generator 4 and printed.

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

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.

In other words, when rENJOY J and key personnel were involved,
Segment patterns for cursor display are prepared directly below each character pattern and interpolation pattern.

The cursor pattern consists of a long cursor (LC) pattern for characters located directly below the character pattern and a short cursor (SO) pattern for interpolated patterns located directly below the interpolation pattern.

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.

Note that 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 a total of 3 cursors, including the long cursor LC directly below "j" and the short cursor SC on both sides, will move to the left. It is turned on.

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

This kind of cursor display is performed, for example, by
This is to indicate the range of the pattern that will be affected by the operation when editing, such as erasing, inserting, or rewriting the character part.

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. Furthermore, RAM 8 has been completely cleared, and "0" has been written therein. At this time, the interpolation flag is in a state where rlJ is stored for the previous address. This state is shown in FIG. 8(C).

In this state, if there is a key human power that is rEJ, then C
PU uses processing code r 45A5J in step Sl.
is generated and stored at the address pointed to by the cursor pointer cp in the RAM fl (step S2), and 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.
By inputting ``45'', a pattern is displayed on ``e'' as shown in FIG. 8(B) (step S3.S
4). At the same time as this operation, the cursor pointer CP changes to CP'
(step S5).

Then, as shown in FIG. 8(A), the currently displayed cursor is turned OFF, and as shown in FIG. 8(B), the next long cursor is turned ON (steps SS, S
7).

Then, the short cursor SC on both sides of the long cursor LC shown in FIG. 8(B), which is currently ON, is turned on.
8(D) in step S8 to turn it off.
RAM B 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 S9, 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 SlO, and if the interpolation flag is ``0'', 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 rlJ in step 813, the process advances to step S15, and the short cursor immediately after the currently lit long cursor is read out. is set to OFF, and if it is "0", the short cursor is set to ON in step S14. Note that if 5 is pressed on the left cursor key, the cursor is moved by the number of presses in step S18 and the processes from step 88 onwards are performed, and when 4 is pressed on the right cursor key, step 65 is performed. Perform the following processing.

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 CB) is reached. In the case of Figure 9 (A), the long cursor and the short cursors to the left and right of it are ON, and as is clear from the RAM address in Figure 1θ (A), the left short cursor is ON. It shows that the processing codes are interpolation patterns "1" and "2", 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 address of the RAM corresponding to the current cursor hill point CP is erased in step Sl, 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 13 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, 2 will be explained below regarding the -stroke key. In the present invention, when given predetermined address information, the character generator 4 and the pattern generator 5 light up both character patterns and interpolation patterns in the order in which they are displayed in one stroke. It is configured as a generator that sequentially generates dot position information (DINO).

The contents are shown in FIG.

That is, as shown in FIG. 12, the old NO information of each pattern is sequentially D from the 1st address to the nth dot.
It is stored as dot position information from INO1 to DINDn.

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

In this state, the control when pressing 2 on the one-stroke key
□The operation is shown in Fig. 13.

That is, in steps Sl and S2, the addresses ADRI and ADR pointed to by the address pointer of RAM [i]
Clear 2.

Next, the process advances to step S3, and the address section is stored in RAM El.
Read the ADRI code information. and step S
Proceed to step 4, - in order to detect the end of the character to be written by hand, the ADRI code is "o", but it is determined whether it is below.
If it is "0", the process ends, and if it is not "0", the process goes to step s5, and the code information is input to the character generator 4 as address information.
The reJ pattern is lit one by one dot by dot.

Next, the process proceeds to step S6, where the address ADR2 is increased by +1, the 4 bits of pen-up information in the RAM of ADRI are set as the upper bits, and the 8 bits are set as the lower bits of the pen-down information of the RAM of A[lR2] with the lower bits of the HP code. (Step 37).

Next, the process advances to step S8, where the display digit is moved one digit to the right, 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 SIQ, 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.

In addition, although the above-mentioned embodiment is limited to English typewriters, it can also be applied to other Japanese cursive scripts such as Japanese kana characters and kanji, and excellent effects can be achieved. can.

Furthermore, when outputting kana and kanji in cursive, it is of course possible to easily perform not only horizontal writing but also vertical writing.

Effects As is clear from the above explanation, according to the present invention, a configuration is adopted in which only the interpolation pattern that connects consecutive cursive characters can be erased. It becomes possible to read the image reliably.
