Description

TECHNICAL FIELD The present invention relates to an electronic device, and more particularly to an electronic device capable of outputting cursive characters.

2. Description of the Related Art Conventionally, typewriters and other electronic devices capable of outputting characters and figures have been known.

The output patterns in these electronic devices are generally characters in print type, and this was sufficient for transmitting character information.

However, it is presumed that electronic devices that can output cursive characters connecting between characters will become common in the future as demand for increasing the expressiveness of the output characters.

For example, if you want to insert handwritten characters in the character information in typeface, if you are not good at handwriting and want to create various documents, or if you feel cold in typeface, or if you want to sign yourself. In order to output beautiful handwritten characters, electronic devices such as a cursive typewriter and a printer are required.

However, when obtaining such an electronic device, the operator must know the range in which the output pattern of the character information (including graphic information) input next to the character displayed on the display affects the current display pattern. It is not possible to confirm what kind of output is given to, or to confirm in what range the output is made.

The present invention has been made in view of the above circumstances, and an electronic device configured so that the effect of the output pattern corresponding to the next key input on the current display state can be surely expressed by the cursor display. Is intended to provide.

Example Hereinafter, the present invention will be described in detail by taking an electronic device of an English typewriter format as an example.

FIG. 1 and the following figures illustrate an embodiment of the present invention.
The figure shows a block diagram of the control circuit.

In FIG. 1, reference numeral 1 indicates a central processing unit (C
PU), which has an indicator (DIS) 2 as an output device.
And a printer (PTR) 3 are connected.

Reference numeral 4 indicates a character generator (CG),
Reference numeral 5 indicates a pattern generator (PG), which are connected to the CPU 1. These generate a pattern corresponding to a given address.

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

The RAM 6 has an address section (R1) and a non-interpolation flag section (R
2), an identification code part (R3) and a point part (R4).

Details of each unit of the RAM 6 will be described later.

On the other hand, reference characters K1 to K8 are a group of input keys connected to the CPU 1. K1 is a type / writing mode conversion key, K2
Is a one-stroke writing mode conversion key, K3 is an erase key, K4 is a right cursor key, K5 is a left cursor key, K6 is an alphabetic character key group, and K7 is? 、! 、! ,,,;, and the like, and K8 is an interpolation pattern cursor deletion key.

With the above configuration, assuming that the mode of the electronic device is now in the print mode, pressing the print / cursive mode conversion key K1 causes the electronic device to be in the write mode, and further pressing K1. And it becomes print mode again. Printing examples of "ENJOY" in the typeface mode and the writing mode are shown in FIGS. 2 (A) and 2 (B).

Next, the control operation until the alphabetic character key group K6 is operated as "ENJOY" to print cursive characters as shown in FIG. 2B will be described.

In the present invention, a character example of a cursive body as shown in FIG. 2 (B) is decomposed into a character pattern as shown in FIG. 3 (A) and an interpolation pattern as shown in FIG. 3 (B). is there.

“ENJOY” is 5 as shown in FIGS. 3 (A) and 3 (B).
It is composed of a combination of 9 character patterns and a total of 9 patterns of 4 interpolation patterns.

Therefore, when the keystroke "ENJOY" is entered, the 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, the positions of the pen-up point PU of the immediately preceding character and the pen-down point PD of the character to be printed subsequently may be determined, and the two may be connected by a straight line or a curved line.

Therefore, in the present invention, the processing code of one character is expressed by, for example, 16 bits as shown in FIG. 3C, and the leading 1 bit requires a character symbol pattern corresponding to this processing code to be an interpolation pattern. It is a non-interpolation flag indicating whether or not to perform it. When it is necessary, "0" is set, and when it is not necessary, "1" is set. What? Ya! Interpolation patterns are not required for symbol patterns such as.

7 bits following this non-interpolation flag is an identification code for identifying a character symbol, and the character generator 4 gives this 7-bit address information,
Generate a pattern of corresponding letters or symbols. The last 8 bits are information for the interpolation pattern, of which the upper 4 bits are the pen down point PD of the pattern of the cursive character to be printed and the lower 4 bits are the pen up point PU.

The pen down point PD and the pen up point PU are positioned as shown in FIG. 4 (A), for example.

That is, 16 points of pen down points PD are determined on the left side of a character, for example, "e", and 16 points of pen up points PU are determined on the right side, and the pen down points PD and pen up points PU which the character should take according to these points are determined. Is decided.

According to ASC II-CODE, the character "e" has an identification code of 45, the pen down point PD is "A", and the pen up point PU is "5". The processing code of is expressed as a BCD code, which is “45A5”. With such a configuration, 16 × 16 = 256 kinds of interpolation patterns are required, and as shown in FIG.
Interpolation patterns corresponding to addresses up to “F” are prepared, and these are stored in the pattern generator 5.

By the way, in the case of this embodiment, the processing code corresponding to the input key is stored in the RAM 6 once and then printed or displayed.

This is so that the cursive characters can be edited later. Now using the above interpolation pattern,
FIG. 5 shows the storage status in the RAM 6 when "ENJOY!" Is input. That is, the non-interpolation flag (C / S), the identification code, the pen down point PD, and the pen up point PU of each character of the cursive are stored using addresses 0 to 5.

Since "!" Does not require an interpolation pattern, the non-interpolation flag (C / S) is "1".

Now the device is in cursive mode and in this state,
When the "E" key is pressed, "45" corresponding to this key is pressed.
A processing code "A5" is generated and stored in the RAM 6, and a character pattern is generated by giving the identification code "45" to the character generator 4 as address information, which is printed or displayed as shown in FIG. 6 (A). Displayed on the container.

Then, when the "N" key is pressed, the processing code "4EB
1 ”is generated and similarly stored in the RAM 6.

At this time, the CPU 1 confirms that the non-interpolation flag of "n" is "0" and then "5", which is the information of the pen-up point PU of the character "e" which is the immediately preceding character, and "n".
Interpolation pattern information "5B" is generated by the information "B" of the pen down point PD of the character "," and the interpolation pattern is generated by inputting "5B" to the pattern generator 5 as address information. 6
It is printed (displayed) following the previous character as shown in FIG.

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. 6 (C). Similarly, "J",
Processing for each key input of “O” and “Y” is performed,
Printed (displayed).

On the other hand, when the last character “!” Is pressed, the processing code “21
00 ”and this code is stored in RAM 6.
The storage state of the RAM 6 at this time is shown in FIG.

The CPU 1 detects that the non-interpolation flag is "1", knows that the interpolation pattern is unnecessary, skips the space for the pattern, and immediately outputs the identification code "21".
A pattern corresponding to is generated by the character generator 4 and printing is performed.

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

In this way, cursive characters are printed (displayed) while determining whether the interpolation pattern is necessary by the processing code.
It becomes possible to do.

By the way, the method of 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 keyed in, a segment pattern for cursor display is prepared directly below each character pattern and interpolation pattern.

The cursor pattern has a configuration in which a long cursor (LC) pattern for characters that is directly below the character pattern and a short cursor (SC) pattern for interpolation patterns that is directly below the interpolation pattern are continuously arranged.

In the state shown in FIG. 7, the current cursor is the short cursor SC immediately after the character "y" and the long cursor LC.
And are on, prompting you to enter the next character.

When the left cursor key K5 is pressed three times in the state shown in FIG. 7, the cursor moves to the left by 3 points, and the long cursor LC directly under "j" and the short cursors SC on both sides thereof are turned ON in total. Has become.

This state is shown in FIG. 9 (A).

This kind of cursor display is performed, for example,
This is because when the character portion of "j" is erased, inserted, or rewritten, etc., the range of the pattern affected by the operation is designated.

About the realistic internal operation of such a display method
It will be as follows when it explains with the flowchart figure of a figure.

That is, in the initial state, the display device 2 is cleared and is in the non-display state. Then, as shown in FIG. 8 (A), only the long cursor LC at the leading character digit position is ON. Further, the RAM 6 is all cleared, and "0" is written in the area where the identification code, the pen down point PD and the pen up point PU are stored. At this time, "1" is stored in the area in which the non-interpolation flag is stored. This state is shown in FIG. 8 (C).
Shown in.

If there is a key input of "E" in this state, C
PU1 processes code "45A5" in step S1.
Is generated and stored in the address pointed to by the cursor pointer CP of the RAM 6 (step S2), and the cursor pointer CP moves to the next address position. This state is the 8th
It is shown in FIG.

Further, the CPU 1 sets the address information “4” for the character generator 4 at the current cursor position for the display unit 2.
By inputting "5", the pattern of "e" is displayed as shown in FIG. 8 (B) (steps S3, S).
4). At the same time as this operation, the cursor pointer CP changes to CP '.
Moves to the position (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 LC is turned on (step S).
6, S7).

Then, the short cursors SC on both sides of the long cursor LC shown in FIG.
In order to turn it off in step S8, FIG.
The non-interpolation flag C / S of the address immediately before the address of the RAM 6 indicated by the current cursor pointer CP 'shown in is read. When the non-interpolation flag C / S is determined to be "1" in step S9, the short cursor SC immediately before the currently illuminated long cursor LC is turned off in step S10, and the non-interpolation flag is "1". If it is "0", the short cursor SC is turned on (step S11).
And

Then, the non-interpolation flag of the address immediately after the address of the RAM 6 indicated by the cursor pointer CP 'is set in step S12.
In step S13, if the non-interpolation flag is "1", the process proceeds to step S15, and the short cursor SC immediately after the currently lit long cursor LC is turned OFF. If "0", the short cursor SC is obtained in step S14. Turn on SC. When the left cursor key K5 is pressed, the cursor is moved by the number of times pressed in step S16, and the processing of step S and subsequent steps is performed. When the right cursor key K4 is pressed, the processing of step S5 and subsequent steps are performed. Do.

In this way, by controlling the short cursor SC for the interpolation pattern and the long cursor LC for the character pattern, it is possible to clearly express the range in which the pattern output on the display corresponding to the next key input affects the current display state. it can.

Effects As is apparent from the above description, according to the present invention, it is possible to display a continuous cursive character pattern by having a cursive character pattern and an interpolating pattern that is continuous between adjacent cursive character patterns. In the electronic device configured as
It has a display control means for displaying a long cursor for designating a character pattern and a short cursor for designating an interpolation pattern, and the character at the position designated by the long cursor is a character on the front side or the rear side of the character and an interpolation pattern. When connected, the short cursor is added to the front or back of the corresponding long cursor so that the display can be controlled. Can be displayed with a short cursor, the above-mentioned area can be confirmed, and the anxiety of the operator can be eliminated.
