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 was sufficient for transmitting textual information. 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.

However, when printing or displaying such cursive characters, it is necessary to know the pen-down point, which is the beginning of writing, and the pen-up point, which is the end of writing, for each character pattern before and after, and to adjust the pen-up points of adjacent characters. Many types of interpolation patterns are required to connect points and pen-down points.

On the other hand, if there is a symbol such as "," or "?" between the cursive character strings or at the end of the character string, these characters and symbols do not need to be consecutive, so interpolation is not possible. A pattern is no longer necessary.

Therefore, unless the processing device is able to reliably determine whether or not an interpolation pattern is required, processing errors will occur.

Purpose The present invention was made in view of the above circumstances, and it is possible to determine whether an interpolation pattern is necessary or not by providing a flag for determining whether or not an interpolation flag is necessary in a processing code. The purpose of the present invention is to provide an electronic device configured to perform the following functions.

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 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 pui. These generate a pattern when given a predetermined address.

In addition, the CPU l 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 13 will be described later.

On the other hand, numerals 1 to 8 represent a group of input keys connected to the CPU I. 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, K6 is a group of alphabet letter keys, and K7 is 71! Symbol keys such as l'1;9 and K8 are interpolation pattern cursor erase keys.

Assuming that the mode of the electronic device is currently set to print mode based on the above configuration, if you press 1 on the print/cursive mode conversion key, the electronic device will change to cursive mode and roughly Press 1 to go back to print mode. The printing example of rENJOY J in print mode and cursive mode is shown in Figure 2 (A) and (B). By operating 6 in the 0th alphabetical character key group as ``rENJOY'', Figure 2 (B) is obtained.
The control operations up to printing cursive characters as shown in FIG. 1 will be explained.

In the present invention, a cursive character string as shown in Figure 2 (CB) is decomposed into a character pattern as shown in Figure 3 (A) and an interpolation pattern as shown in Figure 3 (B). .

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, 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.

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 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, it is set to 0, and if it is not necessary, it is set to 5 cents. 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, 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 identification code of the letter "e" is 45, the pen down point is "A", the pen up point is "3", and the letter "e" is
"'s 16-bit code is expressed in BCD code as r
It becomes 45A3J. With such a configuration, 16×1B=256 types of interpolation patterns are required, and the fourth
As shown in Figure (B), 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 the tree 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.

-1 This is so that the cursive characters can be edited later. Using the above interpolation pattern, rENJOY! FIG. 5 shows the storage situation in RAM B when "" 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 "1".

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, stored in RAM B, and the address information of "45" is sent to character generator 4.
A character pattern is generated by applying
) 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 the RAM 13.

At this time, CPU t confirms that the non-interpolation flag of rnJ is rQJ, and then inputs "5", which is the pen-up point information of the character reJ, which is the immediately preceding character, and "5", which is the pen-down point information of the character rnJ. The interpolation pattern information "5B" is generated by 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). Similarly, "J", "0"
, "Y" are manually processed and printed (displayed).

On the other hand, if you press the last character "1", the code r 21
00J and this code is stored in RAM El. The storage state of RAM l at this time is shown in FIG.

CPU 1 detects that the interpolation flag is rlJ and knows that the interpolation pattern is unnecessary.

Immediately, the character generator 4 generates a pattern corresponding to the character code "21" by skipping a space corresponding to that pattern, and prints it.

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 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.

The first part is about the actual internal operation of such a display method.
The process will be explained as follows with reference to the flowchart shown in FIG.

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 of rE3, then C
PU uses processing code r 45A5J in step Sl.
is generated and stored in the address pointed to by the cursor pointer cp in the RAM 13 (step S2), and the cursor pointer CP moves to the next address position. This state is shown in FIG. 8(D).

Furthermore, CPU t displays address information r for the character generator 4 at the current cursor position for 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 the next long cursor is turned on as shown in FIG. 8(CB) (step S6,
S7).

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 CIS is set to "1".
'', 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 times pressed in step 5113, and the processing from step 86 onwards is performed.
If 4 is pressed on the right cursor, the process from step S5 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, the present invention employs a configuration in which an interpolation flag is provided in the processing code to determine whether or not an interpolation pattern is required. , it is possible to reliably read unnecessary information, prevent erroneous printing or displaying, and use this interpolation flag to control whether the short cursor corresponding to the interpolation pattern is turned on or off.
