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.

However, when obtaining such electronic equipment, the operator must know the extent to which the output pattern of character information (including graphic information) input next to the characters displayed on the display will affect the current display pattern. There may be anxiety about what kind of output will be given to the target, or it may not be possible to confirm whether the output will be within that range.

The object of the present invention is to provide an electronic device configured so that the influence on the target display state can be reliably expressed by means of a cursor display.

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 J 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 ([11!3
) 2 and printer (PTR) 3 are connected.

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

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

The RAM 6 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 8 will be described later.

On the other hand, numerals 1 to 8 represent a group of input keys connected to CPt11. Kl is the print/cursive mode conversion key, ni2 is the single stroke 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 letters, Kl is ? ,! , 9°; symbol keys such as 9, 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. Examples of printing rENJGY J in print mode and cursive mode are shown in FIGS. 2(A) and 2(B). Next, add 6 to the group of letters of the alphabet as "r ENJOY."
) The control operations up to printing cursive characters as shown in () 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.

In order to determine these interpolation patterns, it is sufficient to determine the positions of the pen-up point Pυ of the immediately preceding character and the pen-up point Pυ 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, 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, for a certain character, for example, "r6," 16 pen-down points are determined on the left side, and 16 pen-up points are determined on the right side, and the pen-down points and pen-up points that the character should take are determined according to these points. be done.

Now, according to ASCn-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 reJ
The 18-bit code of is expressed in BCD code as r
It becomes 45A3J. With such a configuration, one type of interpolation pattern (18X 1B = 25E) is required, and as shown in FIG. is stored in

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 El 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 the RAM 11 when "" 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 since "!" does not require an interpolation pattern, the interpolation flag C/S is "l".

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 and stored in RAM 6,
By giving address information of "45" to the character generator 4, a character pattern is generated, as shown in FIG. 6(A).
It is printed or displayed on the display as shown in .

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

Then, when the rNJ 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 rnJ is "0", and then inputs "5", which is the pen-up point information of the previous character "e", and Interpolation pattern information "5B" is generated based on the pen down point information rBJ, and the pattern generator 5
An interpolation pattern is generated by inputting "5B" as 7 trace information into the 7-drace 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 characters rnJ are 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 r 21
0 (IJ) is generated, and this code is stored in the RAM 6. The storage state of the RAM 8 at this time is shown in FIG.

CPIJ I detects that the interpolation flag is "1", knows that the interpolation pattern is unnecessary, skips spaces by that pattern, and immediately sets the character code "21".
A pattern corresponding to the pattern is generated by the character generator 4 and printed.

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, one method of displaying characters and symbols according to 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 long cursor L.
C is ON, prompting you to input the next character. - In addition, if you press 5 three times on the left hand cursor 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 "E", then C
PU processes code r 45A5J in step S1.
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.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 SO, 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 S8, 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 511). 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 S13, 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 times pressed in step 5IEI, and the processing from step 85 onwards is performed.
If 4 is pressed on the right cursor, the process from step 85 onwards is performed.

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. .

Effects As is clear from the above explanation, according to the present invention, display means is provided for displaying a long cursor corresponding to a character height cover pattern corresponding to the input key for the next character and a long cursor corresponding to an interpolation pattern. Since the cursor display means is controlled by character information, the display range of the next character can be displayed with the cursor, and the recording range can be confirmed by the display, eliminating operator anxiety. can.
