Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a character processing device capable of inputting a non-standard character pattern.

[Prior art]

In conventional character processing systems, in order to input a custom character pattern (characters that are not standard equipment), it was necessary to manually enter a character code that corresponds one-to-one with the custom character pattern.

For example, when inputting a custom character pattern, the user had to input the corresponding character code from the keyboard.

Furthermore, in order to make a one-to-one correspondence between character codes and external characters, it is necessary to give instructions to the device in advance before inputting the characters.

[Opening/closing points to be solved by the invention] The present invention is intended to fill in the above-mentioned points, and to allow user to enter a custom character pattern without the need for complicated keystrokes.

Means (and uses) for solving problem C] This misfire is a method for inputting a custom character pattern using a custom character Bakun input means, which is input from the custom character pattern input means, or by converting the input pattern into characters forming a character string. When the user is instructed to input a user character by the user input instruction means and the user input instruction means that indicates that the user input the user input manually, the user inputs the user character having the user character pattern input from the user pattern input means as one of the character strings. To provide a character processing device comprising a character 111 concentration means for processing.

〔Example〕

An embodiment of the present invention will be described below with reference to the drawings.

FIG. 1 is a block diagram of one embodiment according to the present invention.

In the figure, the CPU is a microprocessor that performs calculations for character processing, logical judgments, etc.
Each component connected to these buses is controlled via the control CB and data bus DB.

Address bus AB transfers an address signal indicating a component to be controlled by C of the microprocessor CPU. Control bus CB is MicroPro and Tsusa CPU
Transfers and applies control signals to each component to be controlled.

The data bus DB transfers data between each component device.

The ROM is a control memory that stores a program for the procedure shown in FIG.

27 to M are readable and writable memories, which are external character code registers EXR.

KB is a keyboard having character/symbol input keys 1 such as alphabet keys, hiragana keys, katakana keys, kanji part start/end designation keys, and external character input keys EXT for inputting external character patterns.

DISK is a memory for storing fixed-form documents.
Created documents are stored, and the stored documents are accessed by instructions from the keyboard.

CR is a cursor register, and the CPU reads and writes the contents of the document memory corresponding to the value of the cursor register. A CRT controller CRTC, which will be described later, displays a cursor at a position on the display section CRT corresponding to the address stored here.

The RAM is a writable random access memory having a configuration of 1 word and 16 bits, and is used for temporarily storing various data from each component.

RAM is stored as a 1-word variable in the external character code register EX.
Contains R. The minimum value of the external character code is set as an initial value in the external character code register EXR, and is incremented each time the external character is used.

DBUF is a buffer memory that stores document information etc. input manually from the keyboard KB. The stored codes include custom character codes. In this embodiment, it is assumed that the external character codes are assigned consecutively starting from a certain value.

CRTC is cursor register CR and buffer DBUF
It plays the role of displaying the contents stored in the CRT on the display device CRT.

Further, a CRT is a display device using a cathode ray tube or the like, and a dot-configured display pattern and a cursor display on the display device CRT are controlled by a CRT controller.

Furthermore, CG is a character generator, which generates character signals such as characters, symbols, and cursors to be displayed on the display device CRT.

The character generator CG is equipped as standard (11H
character pattern area (for example, composed of ROM) and a custom character pattern area that is not standardly equipped (for example, R
(consisting of A Si).

The character pattern in the character generator CG is D.
It is associated with the character code of the character information stored in the BUF on an l-by-l basis. The same applies to external character patterns.

TABLET is a tablet for inputting a custom character pattern, and can input the custom character pattern of the 8×8 matrix used in this embodiment.

When you draw a custom character pattern on the TABLET, its coordinate string is output, so you can easily know the drawn pattern matrix.

The character processing device of the present invention, which is composed of each of these components, operates in response to various inputs from the keyboard KB, and when the input from the keyboard KB is supplied, the inscribed signal is first sent to the microprocessor CPU.
The microprocessor CPU reads various control signals stored in the ROM, and various i+ii controls are performed in accordance with these control signals.

Next, character input input in this embodiment will be described in detail.

When inputting a general character, that is, an internal character, the corresponding character key is input from the keyboard KB. To input external characters, manually type the character you want to enter on the TABLET and then press the EXT key.

Memory DBU that stores character information when a character key is pressed
The character code corresponding to that character key is stored in F, and when the foreign character input key is pressed, the foreign affairs code is stored in F. This foreign matter code becomes the value stored in the foreign character code register EXR when the foreign character input key is pressed.

Also, since this value is incremented by one each time the key to enter a custom character is pressed, all the custom characters can be distinguished from others. Also, the character pattern drawn on the tablet TABLET is associated with this external character code and stored in the RAM of the character generator CG.

The character code and external character code data stored in the memory DBUF are displayed on the display CRT by the CRT control device CRTC, and are subjected to various editing operations.

Next, the operation of this embodiment will be explained in detail using FIG. 2.

FIG. 2 shows the operational flow when data is entered manually from the keyboard KB or tablet TABLET. Each step will be explained in detail below.

・Step I: Wait for data input from KB or TABLET. If data input is performed, proceed to step 2. ・Step 2: If character key code is input from KB, proceed to step 3. If the external character input key code is input from KB, proceed to step 4. If coordinate information is input from TABLET, proceed to step 6. If another function key code is input from KB, proceed to step 7.Step 3 Store character codes input from KB in order in memory DBUF. After that, proceed to step 1. Step 4 The value stored in the external character code register EXR is stored in the memory DBUF as a character code.

After that, proceed to step 1. Step 5 Increment (l+1) of the external character code register EXR. Step 6 Based on the coordinate information input from the tablet TABLET, increment the external character pattern storage area of the CG corresponding to the value of the external character code register EXR. Create a character pattern matrix.

(See Figure 3) After that, proceed to step 1. Step 7 Perform processing according to various function keys and proceed to step 1. By executing each of the above steps by the processing unit CPU, the external characters input from the tablet TABLET are processed. The pattern is registered in the character generator CG.

[Other Examples]

(1) In this embodiment, the custom character code and the custom character pattern are
Although a one-to-one correspondence is provided, it is also possible that there is no concept of a private character code. For example, a private character pattern may be directly registered in a buffer that stores character strings.

The handling of control codes shown in Information Processing JIS 6225 is a good example.

(2) In this embodiment, the external character input instruction means is a so-called external character input key. This can be called the private character pattern enter key, but there is also a method that does not use the key. For example, T.A.
When inputting a custom character pattern from BLET, it is also possible to input the custom character pattern by detecting that a period of time has elapsed after drawing the character pattern continuously in time. At this time, the time detection means corresponds to the external character input instruction means.

(3) The non-inventive character input instruction means may instruct after the non-standard character pattern is input, or may instruct the non-standard character input before the non-standard character pattern is input.

(4) The external character input instruction means may be replaced with another external character key. For example, by pressing another character key after inputting a pattern, an instruction to input the external character pattern as a character may be given.
