Description

DETAILED DESCRIPTION OF THE INVENTION The present invention provides a character pattern registration processing method, particularly in a document creation processing device equipped with a display such as a liquid crystal display that can display only a small number of lines, such as one or two lines. The present invention relates to a character pattern registration processing method that allows any desired character pattern, so-called non-standard characters, to be reliably registered.

FIG. 1 is a diagram explaining the correspondence between a dot matrix and characters, FIG. 2 is a diagram explaining an example of a mode of registering a conventional character pattern, and FIG. 3 is a diagram of a display screen of a display device related to the present invention. Give an example.

For example, as shown in FIG. 1, a character 1 displayed on a display device such as a so-called word processor is represented by a dot matrix pattern composed of 5×771 dots 2. That is, for example 16X16,
Each character is expressed in black and white dots such as 24x24 or 32x32. The white/black color of these dots corresponds to 0/1 of a bit, which is the smallest unit of data processing/storage within the processing device.

For commonly used standard patterns of characters,
The information of bit 071 is provided and used in the form of a read-only memory or the like in which the information is stored in a predetermined manner. However, it is desirable to be able to use special patterns other than standard patterns at any time. It is being used to display images.

Conventionally, CRT display devices are often used as display devices for document processing devices. FIG. 2 is a diagram for explaining the manner in which the special pattern is registered when a conventional CRT display device is used. In the figure, 1' is a character area corresponding to the size of character 1 shown in FIG. 1, 3 is a display screen of a CRT display device, 4 is a display area for character pattern registration, and 5 is a cursor.

When a CRT display device is used, a relatively large display screen 3, for example 40 characters x 22 lines, can be provided. Therefore, when registering a custom character, the display area 4 for character pattern registration is displayed on the display screen 3 by specifying pattern registration, and the display area 4 corresponds to the dot 2 shown in Figure 1. Thus, rLX77L character areas are included. And the user
Cursor 5 indicating character position using cursor movement keys
By pressing a specific character key while moving the character, the dot corresponding to the position of the pressed character is processed to become black, thereby registering the pattern.

However, in the case of a CRT display device, there are problems in that it is difficult to make the device smaller and lighter, and it is easy to cause eye fatigue. Therefore, document processing devices that use liquid crystal displays have recently begun to be used. However, in the case of a liquid crystal display, it is difficult to increase the number of characters displayed on one screen due to technical constraints and costs related to the so-called duty ratio. is a trap so that only one or two lines of characters 11 are displayed. In this case, the display screen 10 cannot be provided with the display area 4 for character pattern registration as shown in FIG. Users were not able to register character patterns arbitrarily.

The present invention aims to solve the above problem by preparing a pattern configuration buffer in which each dot of a character pattern composed of a yzXm dot matrix corresponds to one character, and then executing a line from the pattern configuration buffer according to the cursor. In addition to cutting out data in units and displaying it on the display, it also displays the line number where the data is located, and allows you to select any line by moving the cursor and enter pattern data. It is an object of the present invention to provide a character pattern registration processing method that enables character pattern registration from a display device with a small number of display lines, such as a display device. This will be explained below with reference to the drawings.

FIG. 4 shows a configuration of an embodiment of the present invention, FIG. 5 shows an example of the configuration of a display area in an embodiment of the present invention, and FIG. 6 is a diagram illustrating a character pattern registration mode according to the present invention.

In the figure, 21 is a central processing unit (CPU), 22 is a character generator, 23 is a character generator for external characters, 24 is a keyboard Φ control section, 25 is a keyboard, 26 is a display control section, 27 is a display memory, and 28 is a a display device, 29 a memory, 30 a document data processing section, 31 a pattern configuration buffer, 32 a cursor control section, 33 a cursor storage section, 3
4 is a line number display area, 35 is a pattern data display/input area, 36 is a pattern storage area, 40 is a line number display area,
41 represents a pattern fist data display area, and 43 represents a cursor.

The central processing unit 21 is a device that sequentially fetches and executes instructions on the memory 29. The character generator 22 is constituted by, for example, a read-only memory (ROM), and outputs a character pattern image corresponding to a predetermined character code.

Character generator 22 stores pattern images for standard characters. The character generator 23 for external characters is constituted by, for example, a random access memory (RAM). This allows pattern images such as characters, symbols, codes, etc. that are not registered in the character generator 22 to be registered and stored in the process described later, if necessary. Since the pattern image data is provided externally, the characters registered in the character generator 23 for non-standard characters are as follows:
They are called "gaiji". If the pattern image is, for example, 1
If defined by a dot matrix of 6x6, then 16X
Since 16=256, a storage area of 256 bits is required, and an area of 32 bytes is allocated for each character. In addition, the size of the dot matrix, such as a 24×24 dot matrix, is determined depending on the equipment configuration of the system, but in this embodiment, a case of a 16-cut, 6-dot matrix will be described. The same applies to other cases. When a new character is registered in the character generator 23 for external characters, for example, a 2-byte undefined character code is assigned, and the registration location starts from the specified address corresponding to the character code, and the pattern-image 2. The hexadecimal data is read out and displayed.

The keyboard control unit 24 controls the keyboard 25, applies a strobe signal to the keyboard 25 to scan it, detects the press of a key, and sends the character code corresponding to the pressed key to the central processing unit 21. It is intended to convey the following.

The display control section 26 scans the display memory 27,
It controls sequentially reading out the 0/1 pattern image data stored in the display memory 27 and outputting it to the display 28. The display memory 27 has a random storage capacity corresponding to the display screen of the display 28.
It is an access memory, and for example, the display 28 has 1 line x 2
When displaying 0 characters, if one character is composed of a 16x16 dot matrix, it has a capacity of 640 bytes. The display 28 displays characters, symbols, etc. using, for example, a liquid crystal.

A document data processing unit 30 consisting of a group of commands stored in a memory 29 processes document data input from the keyboard 25 under the control of the central processing unit 21, and displays document creation and editing on the display 28. The designated document is printed on a printer (not shown) while being displayed. These can be considered to be the same as before.

The pattern configuration buffer 31 is configured so that when one character is represented by a dot pattern of a 16×16 dot matrix,
The memory has a storage capacity of at least 16x16 characters. A character in the pattern configuration buffer 3101 is determined to correspond to one dot of a character pattern of a custom character to be newly registered or modified. When new registration is started, the contents of the pattern configuration buffer 31 are, for example, blanked or cleared, and when any character is written, the dot corresponding to the character position is treated as black. A dot corresponding to a blank character is determined to be white.

The cursor control unit 32 controls the cursor that indicates the position of the character currently being operated among the information displayed on the display 28, and controls the up, down, left, and right cursor movement keys. Detects a press and moves the cursor up, down, left, or right. In the case of the present invention, when registering a character pattern, one line of character string in the pattern configuration buffer 31 is displayed on the display 28,
The line to be cut out and displayed from the pattern configuration buffer 31 can be changed by using the upward or downward cursor movement key. The cursor storage section 33 stores the position of the cursor, and is managed by the cursor control section 32. That is, the cursor storage unit 33 holds the values of the X coordinate indicating the position in the line and the Y coordinate corresponding to the line number.

The line number display section 34 displays the Y stored in the cursor storage section 33.
Based on the coordinates, the display 28 displays the row number of the pattern configuration buffer 31 in which the information currently displayed on the display 28 is located, as will be described later with reference to FIG. be. By specifying a line number, the pattern of numbers generated by the character generator 22 is transferred to a predetermined area of the display memory 27 and displayed.

The pattern ψ data display/input unit 35 reads the contents of the cursor storage unit 33, extracts one line of character string on the pattern configuration buffer 31 where the cursor is positioned, and writes it in the display memory 27 as a pattern image. , the character string is displayed, and when a character is input from the keyboard 25, the code of the input character is written in the position on the pattern configuration buffer 31 corresponding to the current cursor position. Upon notification of completion of pattern data input, the pattern storage unit 36 sequentially reads out characters from the beginning of the pattern configuration buffer 31 and sets bit values to "0" in order to make blank characters correspond to "white" dots.
The bit value is set to ``1'' so that other characters become ``black'' dots, the pattern data is converted to binary data, and the data is written in a predetermined area of the character generator 23 for external characters. .

The display area 10 of the display 28 is configured as shown in FIG. 5, for example. Assume that the display area 10 has a display size of, for example, 20 characters per line. A two-digit area is prepared as the line number display area 40, and the line number display section 3
4 displays the current line number. As the pattern data display area 41, an area of 16 digits per line is prepared. Here, one line of the pattern configuration buffer 31 is displayed by the pattern reference data display/input section 35. The cursor 43 can be moved within the pattern data display area 41 during pattern registration. When there is an instruction to move the cursor 43 upward or downward, the position of the cursor 43 within the pattern display area 41 is not changed, but instead the displayed content is changed by scrolling.

If the display area 10 is further provided with a dot/no (turn display area 44), it will be easier to register or modify the character/turn. / input unit 35 inputs the contents of the current ) ζ turn configuration buffer 31 to 1
The character's worth of dot-turn data (converted to a turn and written into the display memory 27, thus inputted up to that point) is displayed as a dot image. The conversion from pattern data to dot 9 no turns can be considered to be performed in the same way as the conversion by the pattern storage section 36.

Next, with reference to FIG. 6, a specific novel turn will be explained. For example, as shown in FIG. 6, when registering the postal code mark "〒" in the external character character generator 23, the operator first uses the keyboard 25 to instruct pattern registration. As a result, the contents of the pattern configuration buffer 31 are blanked and cleared, and the cursor is positioned at the character position 50 shown in FIG. This cursor position information is stored in the cursor storage section 33, and initially the contents on the pattern configuration buffer 31 are displayed as in the display area 10' indicated by dotted lines in FIG. In this example, the "black" dot pattern starts from the third line, so by pressing the cursor movement key 46 twice,
Adjust the display area to the third line of the pattern configuration buffer 31. Then, 10 characters are input from the fourth digit. Similarly, the cursor movement key 46 is pressed to input information on the seventh line. The illustrated display area 10 in FIG. 6 shows the state during this input. In the line number display area 40,
It is displayed that the seventh line is currently being processed, and the line position in the turn configuration buffer 31 can be seen. The character to be operated in the horizontal direction can be seen by the cursor 43. .

If it is necessary to re-enter the previous line, the cursor movement key 45 can be used to return to the previous line. When the input of pattern data is completed through the operations described above, the no-hike turn storage unit 36 is activated in response to the completion notification. The pattern storage section 36 converts the contents of the pattern configuration buffer 31 into binary data representing a dot/not turn and registers it in the character generator 23 for external characters. The character position 500 shown in FIG. 6 corresponds to bit 5101 in the character generator 23 for external characters. Thereafter, the notation image registered in the external character character generator 23 is transferred to the display memory according to the specification, so that the postal code mark is displayed on the display in the same way as normal standard characters,
It will also be possible to print.

The above description has been made using an example of a 16×16 dot matrix, but the same applies to other numbers of dots.

The same applies when the display can display not only one line but two or more lines at a time. In particular, in the case of a display device with a display area of two or more lines, when a command force is applied to move the cursor out of the display area of the cursor movement key, the display contents can be scrolled to change the line to be displayed. All you have to do is control it.

As explained above, according to the present invention, even in a document creation processing device using a display device such as a liquid crystal display that cannot have a large number of display lines, desired pattern registration can be performed using a conventional CRT display device. K so that it can be performed in the same way as when using .
