Description

DETAILED DESCRIPTION OF THE INVENTION Technical Field The present invention relates to an electronic device, and more particularly to an electronic device capable of outputting cursive characters.

BACKGROUND ART Typewriters and other electronic devices capable of outputting characters, figures, etc. have been known for some time.

The output pattern of these electronic devices is generally printed characters, which 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.

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 I erase the characters in the cursive string,
When narrowing the spacing between characters, unless a new interpolation pattern is used, the cursive characters that have a new continuity relationship cannot be made continuous.

Purpose The present invention was made in view of the above circumstances, and when a character in a cursive character string is deleted, an interpolation pattern between the cursive characters that has a new continuous relationship is output, and the continuous cursive character string is The purpose of the present invention is to provide an electronic device configured to output text.

Embodiment The present invention will be described in detail below using an English typewriter type electronic device as an example.

FIG. 1 and the following illustrate one embodiment of the present invention, and FIG. 1 shows a block diagram of a control circuit.

In FIG. 1, the reference numeral 1 indicates a central processing unit (CPU), to which a display device (DIS) 2 and a printer (PTR) 3 are connected as output devices.

The reference numeral 4 indicates a character generator (CG), and the reference numeral 5 indicates a pattern generator, which are connected to the CPU 1. These generate a pattern when given a predetermined address.

Further, a random access memory (RAM) 6 is connected to the CPU 1.

RAM6 is address part R1, non-interpolation flag part R
2, an identification code section R3, and a point section R4.

Details of each part of RAM6 will be described later.

On the other hand, symbols K1 to K8 are a group of input keys connected to the CPU1. K1 is the print/cursive mode conversion key, K2 is the single stroke mode conversion key, K3 is the erase key, K4 is the right cursor key, K5 is the cursor key, K6 is the alpha alphabet character key group, K7
teeth? ，! Symbol keys such as , , ;, etc., K8 is a cursor deletion key for interpolation patterns.

Based on the above configuration, if the mode of the electronic device is now set to print mode, then
When the cursive mode conversion key K1 is pressed, the electronic device enters the cursive mode, and when K1 is further pressed, the electronic device returns to the print mode. Examples of printing "ENJOY" in print mode and cursive mode are shown in FIGS. 2A and 2B. Next, a description will be given of the control operation from operating the alphabet character key group K6 to "ENJOY" to printing cursive characters as shown in FIG. 2B.

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

"ENJOY" is composed of a total of nine combinations of patterns, including five character patterns and four interpolation patterns, as shown in FIGS. 3A and 3B.

Therefore, when "ENJOY" is keyed in, a cursive character string can be generated by generating an interpolation pattern as shown in FIG. 3B 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, 16 bits as shown in FIG. This flag is set to "0" if it is necessary, and "1" if it is not necessary. In addition,? or! Symbol patterns such as , etc. do not require interpolation patterns.

The 7 bits following this interpolation flag are codes for identifying characters and symbols, and the character generator 4 generates a corresponding character or symbol pattern based on this 7-bit address information.
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
It is positioned as shown in FIG. 4A.

In other words, for a certain character, for example "e", the pen down point is determined to be 16 points and the pen up point is determined to be 16 points to the right. It is determined.

Now, according to ASC-CODE, the identification code of the letter "e" is 45, the pen down point is "A", the pen up point is "3", and the 16-bit code of the letter "e" is BCD. Expressed in code, it is "45A3". With this configuration, 16 x 16 = 256 types of interpolation patterns are required, and as shown in Figure 4B, interpolation patterns corresponding to addresses from "00" to "FF" are prepared, and these are stored in the generator 5.

By the way, 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, if you input "ENJOY!" now,
Fig. 5 shows the storage situation in RAM6. 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".

Now, the device is in cursive mode, and in this state, if you press the "E" key, the code "45A5" corresponding to this key will be generated, and the RAM6
By supplying the address information "45" to the character generator 4, a character pattern is generated and printed or displayed on a display as shown in FIG. 6A.

As is clear from Figure 6A, this character has
Displayed with an interpolation pattern already attached.

When the "N" key is subsequently pressed, the code "4EB1" is generated and similarly stored in RAM6.

At this time, CPU1 confirms that the non-interpolation flag of "n" is "0", and then inputs "5", which is the pen-up point information of the character "e", which is the immediately preceding character, and the character "n". Interpolated pattern information ``5B'' by pen down point information ``B''.
By inputting "5B" as address information to the pattern generator 5, an interpolation pattern is generated, and this interpolation pattern is printed (displayed) following the previous character as shown in FIG. 6B. .

Thereafter, the character identification code "4E" is given to the character generator 4 as address information to generate a character pattern, and the character "n" is printed (displayed) as shown in FIG. 6C. Thereafter, in the same manner, processing for each key input of "J", "O", and "Y" is performed and printed (displayed).

On the other hand, if you press the last character "!", the code "2100" will be generated and this code will be stored in RAM6. The storage state of the RAM 6 at this time is shown in FIG.

CPU1 detects that the interpolation flag is "1" and knows that the interpolation pattern is unnecessary,
A space corresponding to the pattern is skipped and a pattern corresponding to the character code "21" is immediately generated by the character generator 4, and printing is performed.

This state is the state shown in FIG. 6D.

In this way, it is possible to print (display) cursive characters while determining whether or not an interpolation pattern is necessary based on the processing code. By the way, the method for displaying characters and symbols in the present invention is the seventh
It is accompanied by a cursor display as shown in the figure.

That is, when "ENJOY" is entered by key, a segment pattern for cursor display is 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 interpolation patterns directly below the interpolation pattern.

In the state shown in FIG. 7, the short cursor SC and long cursor LC immediately after the character "y" are currently ON, prompting the user to input the next character.

Note that in the state shown in Figure 7, press the left cursor key K5.
When you press 3 times, the cursor moves 3 points to the left, and a total of 3 cursors are turned on: the long cursor LC directly below the "j" and the short cursor SC on both sides.

This state is shown in FIG. 9A.

The reason why such a cursor is displayed is to indicate, for example, the range of the pattern affected by the operation when editing, such as erasing, inserting, or rewriting the letter "j".

The actual internal operation of such a display method will be explained below with reference to the flowchart of FIG.

That is, in the initial state, the display 2 is cleared and is in a non-display state. As shown in FIG. 8A, only the long cursor at the first character digit position is turned on. Also, RAM6
is all cleared and "0" is written. At this time, the interpolation flag is in a state where "1" is stored for the previous address. This state is shown in FIG. 8C.

In this state, if the key input is "E", the CPU generates a processing code "45A5" in step S1 and moves the cursor pointer of RAM6 to
Store this at the address pointed to by CP (step
S2), the cursor pointer CP moves to the next address position. This state is shown in FIG. 8D.

Furthermore, the CPU 1 inputs address information "45" to the character generator 4 at the current cursor position on the display 2, thereby displaying a pattern on "e" as shown in FIG. S3, S4). At the same time as this operation, the cursor pointer
CP moves to the position of CP' (step S5).

Then, as shown in FIG. 8A, the currently displayed cursor is turned OFF, and as shown in FIG. 8B, the next long cursor is turned ON (steps S6 and S7).

Then, the short cursor SC on both sides of the long cursor LC shown in Figure 8B, which is currently ON.
In order to turn ON and OFF the current cursor pointer CP' shown in FIG.
Read the interpolation flag C/S at the address immediately before the address in RAM6. Then, the process advances to step S9, and when it is determined that the interpolation flag C/S is "1",
In step S10, the short cursor SC immediately before the currently lit long cursor is turned OFF.
If the interpolation flag is "0", the short cursor
Turn SC ON (step S11). 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 address immediately after the currently lit long cursor is read out. shoot cursor
OFF, and if it is "0", the shot cursor is turned ON in step S14. If the left cursor key K5 is pressed, the cursor is moved by the number of keys pressed in step S16, and the processes from step S6 onwards are performed, and when the right cursor key K4 is pressed, the processes from step S5 onwards are performed. Let's do it.

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 will have on the current display state. .

By the way, in the above example, in order to erase the character pattern "j", move the cursor below that character as shown in Figure 9A and press the erase key K3, and the character pattern as shown in Figure 9B is pressed. state.
In the case of Figure 9A, the long cursor and the short cursors on its left and right are ON.
This is clear from the RAM address in Figure 10A, where the short cursor on the left is connected to the interpolation patterns "1" and "2", the character pattern "4A" corresponding to the long cursor, and the short cursor on the right. This indicates that it is the processing code for the corresponding interpolation pattern "8B".

When the erase key K3 is pressed in this state, the first
As shown in the flowchart of Figure 2, in step S1 the RAM address corresponding to the current cursor pointer CP is erased. Then, in step S2, the processing code of the address below the erased address is rewritten,
In step S3, information on the pen up point of the character "n" and information on the pen down point 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 press the interpolation pattern deletion key K8 if you want to delete only the interpolation pattern, the current
Only the interpolation pattern corresponding to the shot cursor that is ON is erased.

At this time, the contents of RAM6 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. This is very effective when you want to separate each character with ``etc'' 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 is output that continues the characters that have a new continuous relationship. , it is possible to output a completely continuous cursive character string.
