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 estimated that electronic devices capable of outputting cursive characters with continuous character spacing 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. To output beautiful handwritten characters, use a cursive typewriter ml
Electronic equipment such as a printer is required.

Purpose The present invention was made in view of the above circumstances, and an object of the present invention is to provide an electronic device configured to selectively output cursive.

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 1 is the central processing unit
pu), which has a display (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 put. These generate a pattern when given a predetermined address.

Additionally, CPU 1 has random access memory (RAM).
)6 is connected.

The RAM 8 is composed of an address section R1, a non-interpolation flag section R2, 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, reference numeral Kl-8 is a group of input keys connected to the CPU t. K1 is the print/cursive mode conversion key, K
2 is the one-stroke writing mode conversion key, K3 is the erase key, 4 is the right cursor key, K5 is the cursor key, K8 is a group of alphabet letters, and K7 is the ? + i + '+;1
K8 is a cursor erase key for interpolation patterns.

Assuming that the mode of the electronic device is currently set to the print mode based on the above configuration, when the print/cursive mode conversion key Kl is pressed, the electronic device changes to the cursive mode, and roughly speaking Kl. Press it to go 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, Alphabet/
The control operation up to the printing of cursive characters as shown in FIG. 2 CB) 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 nine combinations of patterns, including five character patterns and four interpolation patterns, as shown in FIGS. 3(A) and (B).

Therefore, when the keys Il and ENJOY J are entered manually, a cursive character string can be generated by generating an interpolation pattern as shown in FIG. 3(B) and connecting adjacent characters.

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, for example, 18 bits 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, "O" is set, and if it is not necessary, rlJ is set. In addition,? or! Symbol patterns such as , etc. do not require interpolation patterns.

The 7 bits are a code for identifying character symbols, and the character generator 4
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, for a certain character, for example "e", set the pen down point to IB point on the left side and the pen up point to the right side by 1.
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 ASCn-11:ODE, the identification code of the letter "e" is 45, and the pen down point rAJ,
The pen up point is "3".

The 18-bit code for the letter "e" is expressed as r45A3J in BCD code. With such a configuration, 1EiXte=258 types of interpolation patterns are required, and as shown in FIG. 4(B), from "00" to r FF
Interpolation patterns corresponding to addresses up to J 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 8 and then printed or displayed.

This is so that the cursive characters can be edited later. Now, using the interpolation turns as above,
rENJOY! FIG. 5 shows the storage situation in the RAM 13 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 G/S is "1".

The device is now in cursive mode, and in this state,
When you press the "E" key, this key is the first J-...
Two codes r 45A5J are generated and RAM 8
By supplying the address information of "45" to the character generator 4, a character turn is generated and is printed or displayed on the display as shown in FIG. 6(A).

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 fi.

At this time, CPU 1 confirms that the non-interpolation flag of rnJ is "0", and then inputs "5", which is the pen-up point information of the character reJ, which is the immediately preceding character, and the pen-down point information of the character rnJ. Interpolation pattern information "5B" is generated using the 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). The same goes for 'rJJ
, rOJ, and rYJ are manually processed and printed (displayed).

On the other hand, if you press the last character "!", the code r 21
00J and this code is stored in RAM 8. The storage state of the RAM 8 at this time is shown in FIG.

The CPU 1 detects that the interpolation flag is "1", learns that the interpolation pattern is unnecessary, skips spaces by that amount, and immediately creates a pattern corresponding to the character code Fr2LJ in the character generator 4. is generated and printed.

This state is 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 patterns are a long cursor (LC) pattern for characters directly below the character pattern, and a short cursor (SC) pattern for interpolation patterns directly below the interpolation turn.
The pattern is arranged in a continuous manner.

In the state shown in Figure 7, the current cursors are the short cursor SC immediately after the character rVJ, and the long cursor L.
G 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 the long cursors I and C directly below "j" and the short cursors SC on both sides will move to the left by 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. Furthermore, RAM 8 has been completely cleared, and "0" has been written therein. At this time, the interpolation flag is in a state where "Il" is stored for the previous address. This state is shown in FIG. 8(C).

In this state, if we now have the key human power of rEJ, c
pj is the processing code r 45A5J in step Sl.
is generated and stored in the address pointed to by the cursor pointer cp in the RAM 8 (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.
45'', reJ displays the pattern as shown in FIG. 8(B) (step S3,
S4). At the same time as this operation, the cursor pointer CP changes to C2.
It moves to position 2 (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(CB) (step S8,
S? ).

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 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 S9, and the interpolation flag C/S is rl.
If it is determined that it is J, the short cursor SC immediately before the currently lit long cursor is turned OFF in step SIO, 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 "1" in step S13, 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 S1B and the processes from step 86 onwards are performed, and when 4 is pressed on the right cursor key, the processes from step 55 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. It shows that these are the processing codes of the interpolation patterns rlJ and r2J, the character pattern "4A" corresponding to the long cursor, and the 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 "O" 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 RAM θ are saved and the position of 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 configured as generators that sequentially generate dot position information (DIND) that lights up both character patterns and interpolation patterns in the order in which they are displayed in one stroke when given address information. It is.

The contents are shown in FIG.

That is, as shown in FIG. 12, the DINO information of each pattern is stored in order from address 1 as dot position information from 1st to nth dots DIND1 to DINDn.

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

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

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

The process then proceeds to step S3, where the address section reads the code information of ADR1 in RAM 8. And step S4
-A to detect the end of the character to be written.
Determine whether the code of DR1 is rQJ 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, the pen-up information 4 bits of the RAM of ADRI are set as the upper bits, and the pen-down information 4 of the RAM of ADR2 is set as the upper bit.
The 8 bits with the lower bits as the lower bits are used as HP code information (step S7).

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 SIO, 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 description, according to the present invention, the character generator outputs a cursive character pattern, the pattern generator outputs an interpolation pattern that makes the spaces between adjacent characters continuous, and the cursive output mode key By providing this, an excellent effect can be obtained in that not only printed characters can be output, but also cursive characters with continuous character spacing can be selectively printed or displayed.
