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 were generally printed characters, which were sufficient for transmitting textual information. However, in the future, as the expressive power of output characters was required to be increased, It is predicted that electronic devices that can output cursive characters with connected characters 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.

On the other hand, when trying to output cursive characters, in addition to the cursive characters themselves, an interpolation pattern that makes the cursive characters continuous is required. Unless a large number of these interpolation patterns are prepared, cursive characters with continuous character spacing cannot be printed or displayed.

However, when deleting characters in a cursive character string to close the spaces between the characters, it is not possible to make the cursive characters in a new continuous relationship continuous unless a new interpolation pattern is used.

Purpose The present invention has been made in view of the above-mentioned circumstances.When a character in a cursive character string is erased, an interpolation pattern between the cursive characters that has a new continuous relationship is output, and the continuous cursive character string is The object of the present invention is to provide an electronic device configured to output characters.

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 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 put't. When given a predetermined address, these generate a corresponding node.

Additionally, CPU 1 has random access memory (RAM).
) 8 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 e will be described later.

On the other hand, numerals 1 to 8 represent a group of input keys connected to the CPU 1. K1 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, K8 is a group of alphabet character keys, and K7 is the ? ,! , bite.

Symbol keys such as 9 and K8 are interpolation pattern cursor erase keys.

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. Examples of printing rENJOY J in print mode and cursive mode are shown in FIGS. 2(A) and 2(B). Next, operate the alphabet letter group KB as "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 nine combinations of patterns, five character patterns and four interpolation patterns, as shown in FIGS. 3(A) and CB).

Therefore, when rENJOY J is 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 character to be printed subsequently, 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, "O" is set, and if it is not necessary, rlJ is set. In addition,? In the case of symbol patterns such as or 1, no interpolation pattern is required.

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-C0DH, the character reJ (7
) The identification code is 45, and the pen down point rAJ
, the pen-up point is "3", and the 16-bit code of the character reJ is r45A3J when expressed in BCD code. With this configuration, 18x 1B = 256 types of interpolation patterns are required,
As shown in FIG. 4CB), interpolation patterns corresponding to addresses from "00" to rFFJ 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 pattern above,
rENJOY! Figure 5 shows the storage situation in RAM 8 in the case where , + is input. That is, the code of each character in cursive and the pen-down and pen-up points are stored using addresses 0 to 5. .

Note that when "1", no interpolation pattern is required, so the interpolation flag C/S is rlJ.

The device is now in cursive mode, and in this state, r

) is printed or displayed on the display.

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 i has the non-interpolation flag of rnJ
□After confirming that it is rOJ, the previous character r
Interpolation pattern information "5B" is generated using "5", which is the pen-up point information of the character eJ, and "B", which is the pen-down point information of the character rnJ, and "5B" is sent to the pattern generator 5 as address information. The input generates an interpolation pattern, and this interpolation pattern is printed (displayed) following the previous character as shown in FIG. 6(B).

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'
, rY'' 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 6.

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

CPU 1 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.

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 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 mouth 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 87, the cursor moves 3 points to the left, and a total of 3 cursors, the long cursor LC directly below "j" and the short cursor SC on both sides of it, are turned on. It becomes.

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 "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 is processing code r 45A5 in step S1
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.
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 C22.
(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, 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.
The current cursor pointer CP' (7) shown in tR

/Read S. Then, the process advances to step S8, and the interpolation flag C
When it is determined that /S is "l", 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)
shall be. Then, RA indicated by cursor pointer CP'
Step S sets the interpolation flag of the address immediately after the M address.
If this interpolation flag is rlJ in step 313, the process advances to step S15, and the short cursor immediately after the currently lit long 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 31 [i, and the process below step 85 is performed, and when 4 is pressed on the right cursor key, step 8
5 or less.

In this way, by controlling the short cursor for interpolation patterns and the long cursor for character patterns, it is possible to clearly express the influence of the pattern output on the display corresponding to the next key input on the current display state. be able to.

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 for the interpolation patterns "rl", "r2", 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 "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 and press 8 on the compensation pattern deletion key, only the interpolation pattern corresponding to the short cursor that is currently ON will be deleted.

At this time, the contents of RAM B 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.

Effects As is clear from the above explanation, according to the present invention, even if characters in the output cursive character string are deleted, a new interpolation pattern that continues the characters that have newly become continuous is output. , it is possible to output a completely continuous cursive character string.
