Abstract

PURPOSE:To facilitate an easy input of plural characters which are not curved on a key top by feeding previously both the key array and key information of a key input part to a memory part and then displaying the desired key array and information when necessary. CONSTITUTION:The information necessary for production of a document which is supplied from a key input part A undergoes an editing process B and a display process C to be displayed at a CRT display part D. When a specific key of the part A is fed, a key array display indication means E gives an indication to read out the information on the character codes which are not carved on key tops, e.g., the special information for scientific calculations in the same array as that of the part A stored in a memory means F. This read-out information is displayed at the part D via a key array display means G. The various specific character codes are stored to the means F for each group, and a desired symbol array is read out with operation of keys of the part A and displayed D. Thus a document is fed and edited based on the display D. This attains an input of a large number of character codes with a small number of key tops.

Description

DETAILED DESCRIPTION OF THE INVENTION Technical Field The present invention relates to a document processing device having document creation and editing functions.

Conventionally, in document processing devices such as document creation devices, the contents of key information, such as characters, Characters indicating functions etc. are engraved.

However, if the content of key information is engraved on the key top etc. in this way, if there is a large number of information for one key, it may not be possible to engrave all the information content on the key top etc., resulting in loss of versatility. Even if the stamp can be engraved, it becomes difficult to see and the operability becomes inconvenient.

In particular, if you expand the number of characters that can be processed without changing the keypad, for example if you have a type printer and change the type wheel from standard to scientific, then the standard key layout can be specified. The keys will be assigned to scientific and technological characters.

For example, if the position of ``...'' on the standard type wheel is replaced with ``ω'' on the old technical type type wheel, the information ``ψ'' is entered by operating the key ``'' on the keyboard. It turns out.

In this way, when the correspondence between the keys on the keyboard and the information content to be input is changed, it becomes difficult to grasp the information content that can be input with a specific key, and operability deteriorates.

Purpose This invention has been made in view of the above points, and an object thereof is to improve the operability of a document processing device.

For example, when a specific key of the key operator A is operated, the key layout display instruction means E displays display instruction information that instructs the display of the key layout and key information of the key operator A stored in the storage means F. Output.

When display instruction information is input from the keyboard layout display instruction means 13, the keyboard layout display means G displays the key layout and key information of the key input section A stored in the storage means F on the display section.

Therefore, if the storage means F stores, for example, the key arrangement and key information for science and technology, the standard key manual section A
When using the keyboard for science and technology, the stored keyboard layout and key information for science and technology can be displayed on the display, allowing key operations to be performed while viewing the display.

FIG. 2 is a perspective view showing the appearance of an example of a document processing device embodying the present invention.

In the figure, this document processing device includes a keyboard 1, which is a key input section for inputting characters, formats, and control information necessary for creating a document, and a document processing device based on the feelings input from this keyboard 1. It consists of a main body 3 having a CRT display device 2 (hereinafter simply referred to as rCRTJ) as a display section, a printer 4 for printing created characters, a floppy disk device 5 for storing documents, and the like.

The keyboard 1 is a graphic character system consisting of character keys for inputting character information such as symbols, numbers, alphabets, kana, etc., and a shift key for selecting one of six types of characters using the character keys. Mode selection for selecting either a standard mode in which display processing is performed using the key group 10 and characters engraved on the character keys, or an extended mode in which display processing is performed including characters other than this standard mode, that is, characters not engraved on the character keys. Key 11, add, delete.

In the figure, the key human power determination circuit 20 includes a keyboard 1
It is determined whether the input information is character information, format information, control information, etc.

Then, according to the determination result, if the character data is SC due to the operation of the character keys, the character input control circuit 21 receives mode data SI indicating selection and cancellation of the extended mode by operation of the mode selection key 11 (tl'). is a D-type flip-flop j circuit (hereinafter referred to as rD-FFJ) 22, and other key operations.

If it is function data SF such as control, the data is transferred to the function control circuit 23, respectively.

The character input control circuit 21 manages the pointer of the edit buffer 24 and sets the input character data SC in the edit buffer 24 as well.

r, :+ -FF 22 outputs a Q output whose state is inverted each time the mode data S is inputted, that is, each time the mode selection key 11 is pressed, as mode designation data DI, and this D-FF 22 and the mode selection key 11 (FIG. 1) constitute a key layout display instruction means.

The function control circuit 23 outputs, for example, cursor data DF for instructing cursor movement based on the input function data SF.

The non-volatile memory 25 is a storage means that stores the key layout and key information data of the keyboard 1 in the extended mode (hereinafter both will be collectively referred to as "key layout data").

Note that this storage means can also be configured by loading a nonvolatile memory from a ROM or a floppy disk of the floppy disk device 5, for example.

The display control circuit 26 also serves as a key arrangement display means, and receives pointer data DP for determining the cursor position from the character input control circuit 21, mode designation data DI from the D-FF 22, and cursor data DF from the function control circuit 23. .

Input the text data DC from the editing buffer 24 and the key layout data DK from the non-volatile memory 25, and display the text data DC from the editing buffer 24 and the key layout data DK as necessary on the screen of the CBr4. control for.

This display control circuit 26 is configured as shown in FIG. 4, for example.

In the figure, a microcomputer (hereinafter referred to as "microcomputer") 31 includes a CPU (central processing unit), a program memory (RoM), and a data memory (RAM).
r It consists of an I/O (input/output device), etc., and controls the display by CBr4 based on the program stored in the ROM.

The CRT controller 32 controls the CBr4.
It performs various controls based on the clock pulse C'LK from the clock generator 33.

Refresh memory (hereinafter referred to as rV7RAMJ) 34
is the data memory for graphic characters,
When accessed by the microcomputer 31 or the CRT controller 32 via the multiplexer 35, and by the microcomputer 31.

When the display data is written to the address specified by the address data A g ''-A n via the bus driver 36 and accessed by the CRT controller 32, the display data specified by the address data ADO to A D , n is written. The display data at the specified address is read out.

The character generator 37 is a standard mode dot pattern generator, inputs display data read from the V-RAM 34 via a multiplexer 39 controlled by the microcomputer 31, and transmits the display data to the CRT controller! Rusk address data RAO~RA from I+2
The data is converted into dot data for display at the timing specified by n.

Another character generator 68 is an extended mode dot pattern generator, which inputs the display data read out from the Y-RAM 4 via the multiplexer 3.
The display data is the rusk address data RA o~RA
The data is converted into display dot data at the timing specified by n.

These character generators 37.38.

Both are configured with a ROM or the like, and the only difference between the standard mode and the extended mode is the dot pattern of the address specified by the display data.

For example, regarding a character common to both the standard mode and the extended mode, such as the character rAJ, each of the character generators 37 and 38 generates a dot-turn of the character rAJ in response to display data corresponding to a key operation of the character rAJ.

On the other hand, if the key for a character that is different between the standard mode and the extended mode, for example, the letter r'' in the standard mode, corresponds to the letter ``ψ'' in the extended mode, it corresponds to the key operation for the letter ``''. For the display data, the character generator 37 generates a dot pattern of the character "r''", and the character generator 38 generates a dot pattern of the character "■".

The display dot data output from these character generators 37 and 38 is serially processed by shift registers 41 and 42 which input pulses in dots from the clock generator 63, although the signal lines are not shown. The data is converted into data and input to the video control circuit 44 via the OR circuit 43.

This video control circuit 44 generates a video signal by synthesizing the cursor display signal CU from the CRT controller 32 and the display timing signal DT indicating the horizontal and vertical scanning image display period, and the dot data DS from the OR circuit 43. This video signal and the CRT controller 32
The horizontal and vertical synchronizing signals H3YNC and VSYNC from the CRT 2 are combined and output to the CRT 2 as a composite signal.

Next, the operation of the embodiment configured as described above will be explained with reference to FIGS. 5 and 6.

FIG. 5 is a flowchart showing an example of a document creation/editing operation executed by the control section of FIG. 2.

In the figure, in the initial state when the power is turned on, D-FF2

The mode is set to display processing using the characters (key information) engraved on the character keys, and the buffer pointer of the editing buffer 24 is set to the beginning.

In the standard mode, the microcomputer 31 shown in FIG. 4 controls the multiplexer 3 so that the display data read from the V-RAM 34 is input to the character generator 37, and the text display area of the CRT 2 is expanded to 24 lines. I will make it happen.

In this state, wait for key power from keyboard 1-51.

If there is key manual power, the key manual power determination circuit 20 determines whether the input data is character data SC, mode data S, or function data SF.

If the determination result is character data SC, this character data SC is transferred to the character input control circuit 21, and the character input control circuit 21 controls character input such as storing the data in the editing buffer 24.

If the key manual determination result is function data SF, this function data SF is transferred to the function control circuit 26 and the function control circuit 2
! 1 outputs a signal according to the data, and function control is performed.

Further, if the key manual determination result is mode data SI, this mode data SI is transferred to the D-FF 22,
The mode designation data pI, which is the Q output of the D-FF'22, is inverted.

And, the microcomputer 31 in FIG. 4 is this D-F F22
It monitors the mode designation data DI from and checks whether the mode designation data DI is 0'' to determine whether or not it is the standard mode.

If this determination result is standard mode, multiplexer 3

'After converting the display data from AM34 into a dot pattern by the standard mode character generator 37, set the display data write address area of V-RAM34 so that the text display area of the CRT2 screen has 24 lines. do.

On the other hand, if the determination result is not the standard mode, that is, the extended mode, the multiplexer 3 is switched to the character generator 38 side, and the display data from the V-RAM 34 is transferred to the extended mode character generator 38.
8 so that it is converted to a dot pattern.

Then, the key layout data DK stored in the non-volatile memory 25 in FIG. , displayed after the line.

Thereafter, the text data area scrolls up the line before the cursor and places the cursor at the top of the CRT 2 screen.

In this way, the key arrangement and key information in the extended mode are displayed on the CRT 2.

FIG. 6 is a diagram illustrating an example of the keyboard arrangement and display of key information in the extended mode.

In the figure, the screen 2a of the CRT 2 has a text display area TP and a key layout display area Ire K in the extended mode.
]), a document is displayed in the text display area TP, and a keyboard layout and key information are displayed in the keyboard layout display area.

The key arrangement and key information shown in this figure are the key arrangement and key information of the character keys of a keyboard for scientific and technical calculations.

It should be noted that one key displayed in the figure is composed of three angline characters horizontally and three ruled lines vertically.

If you configure the keys to be displayed like this, there will be 37 columns horizontally when displayed with a standard keyboard layout.

Although 13 lines are required vertically, 80 columns are sufficient for horizontally displaying additional function keys.

In this way, in this document processing device, the key arrangement and key information in the extended mode are displayed by operating the mode designation key 11 on the keyboard j.
You can create a document while checking the key arrangement and key information, and you can easily enter characters that are not engraved on the document key.
