Description

DETAILED DESCRIPTION OF THE INVENTION Technical Field of the Invention The present invention relates to a data processing device fVc, and more particularly to a data processing device having a purple display section that displays a display pattern on a display that corresponds to display data input by a data input means. Regarding.

Background of O technology Data input means such as keyboard and display section? In the data processing apparatus having the above-mentioned keyboard, when a key on the keyboard is pressed, a display pattern such as a character 1 figure corresponding to the pressed key is displayed on the display. The location where this display pattern is displayed is determined by a cursor displayed on the display. The operator can use this cursor movement key to move the cursor to the desired position before pressing the key manually! li
By moving the character to a desired position on the display, a desired character 1 graphic pattern can be displayed at a desired location on the display.

Therefore, the keyboard, the display? A data processing device is equipped with characters on the display.

You can freely set and change the display format of figures, document 9 create figures 1 edit? It has the great advantage of being easy and quick to carry out. PRIOR ART AND PROBLEMS FIG. 1 is a diagram showing the external appearance of the above-mentioned data processing apparatus. 1 is the console, 4 is the keyboard.

4a, 4b numeric keys, 4c cursor movement keys.

6 is a display, and 6a is a cursor.

Inside the console 1 are the numeric keys 4a and 4 on the keyboard 4.
A control unit that performs all processing of data input by b is stored. The entire operation of the device will be explained below.

The operator presses the numeric keypad 4 a + on the keyboard 4.
4 When the specified key in b is pressed, console 1
The internal control unit displays a display pattern such as characters, figures, etc. on the 6-screen screen corresponding to the pressed key. The position on the display 6 where all of the display patterns should be displayed is set in advance by the cursor 6a. However, in conventional data processing devices, all of the display patterns corresponding to the pressed keys are displayed with the cursor 6a. After being displayed at the position, the cursor 6a was controlled to be automatically shifted to the right. That is, as illustrated in Figure 1, when the key for the letter "I" on the numeric keypad 4b is pressed, the character pattern "I" is displayed on the display 6, and the cursor 6a is shifted to the right by one display area. Ru. Therefore, if there is a character to be displayed at the position of the cursor 6a shown in FIG. will be further shifted one place to the right.

However, if there is no character to be displayed at the position of the cursor 6a and, for example, the operator wants to display all the next characters at the position 6b below the character "i", the operator must press the cursor movement key 4 from the cursor 6a.
After moving to the next display position 6b with C, it was necessary to press all of the predetermined character keys in order to display all of the predetermined characters.

In this way, conventionally, the cursor movement direction after a pattern is displayed by a key-in operation is always in the direction of one foot.

Therefore, when sequentially displaying patterns in a direction different from the cursor movement direction, it is necessary to repeat the operation of correcting the cursor position using the cursor movement keys every time a pattern is displayed, which not only makes the operation more complicated but also leads to errors. There is a drawback that display data is often inputted to a certain position.

OBJECT OF THE INVENTION The purpose of the present invention is to eliminate all of the drawbacks of the prior art as described above, by simplifying the display data input operation, making it faster than document creation or graphic creation, and reducing erroneous data input operations. The purpose is to provide a data processing system that can be used to analyze data.

O Structure of the Invention In order to achieve all of the above objects, the data input device of the present invention comprises:
A data input means and a pattern corresponding to the data input by the input means? A processing unit that displays information in a predetermined area on the display? and the processing section displays a cursor indicating a display area for data to be input next on the display, and when display data is given to the cursor display area, moves the cursor in one step direction to display the next input data. As shown in display area 2, in a data processing device that performs full cursor control, a storage section is provided in which a movement mode for specifying the movement direction of the cursor can be set, and the processing section controls the cursor control based on the movement mode stored in the storage section. The entire feature is that it can be moved.

Embodiment 0 of the Invention FIG. 2 is a block diagram showing one embodiment of the data processing apparatus of the invention, and FIG. 3 is an operation flowchart in the embodiment shown in FIG.

In FIG. 2, 2 is a processing unit (CPUI, 31d keyboard interface, 4 is a keyboard, 5 is a display interface, 6 is a CRT display, and 7 is a memory.

Also, in Fig. 3, DCP is the screen count-up register or its contents, and MCP is the memory count-up register or its contents. show.

In this embodiment, a movement mode that instructs the cursor movement direction after key-in is used. Set. That is, normal mode; cursor moves to the right after key-in L mode; cursor moves to the left after key-in U mode; cursor moves up after key-in D mode; cursor moves down after key-in These modes can be switched using the modes on the keyboard 4. This is done by pressing the switch key 4°.

The mode switching key 4' may be provided on the keyboard 4, or may be replaced with one of the ready-made numeric keys.

The CPU 2 has a mode register 7m7 in the memory 7, and each time the mode switching key 41 is pressed, the mode register 7a is
The cursor movement mode is determined by the contents of the mode register 7a of the vCCPU 2 and the i count up. This is 2 as shown in the table below for mode register 7a7.
This is achieved by using it as a bit counter.

That is, each time the switching key 41 is pressed, the normal mode to D mode are sequentially rotated and switched.

The constituent sounds of the embodiment shown in Box 2 will be explained below.

In the example, common bus 8? Through, CPU2, memory 7
, a data input means consisting of a keyboard 4 and a keyboard interface 3, a display section consisting of a display 6 and a display section interface 5, and a display section consisting of a display section 6 and a display section interface 5 are used to send and receive data. A key-in display register 3a+ for displaying the pressed key and a code register 3b for storing the key code corresponding to the pressed key are provided. The display interface 5 is also provided with a cursor position register 5a in which position data (screen address) to be displayed on the cursor is stored, and a screen memo 1J5b containing display data to be displayed on the display 6. The addresses of the screen memory 5b have a one-to-one correspondence with the screen addresses of the nice play 6. For example, the display data stored in 5b' represents a pattern to be displayed at the screen address 6' on the display 6.

In addition to the above-mentioned mode register 7a, the memory 7 stores codes keyed in from the keyboard 4. An address register 7b indicating the code store area 7 to be stored and the address 7 to be stored, and a screen count up register 7 in which the amount of cursor movement corresponding to each cursor switching mode is stored.
b.

A memory count up register 7C is provided in which the amount of movement of the address value of the address register 7a is stored. The table below shows the correspondence between the values set in the screen count-up register 7b and memory count-up register 7cVC and the cursor switching mode.

here C: Amount of memory required for one display data (number of bytes) L: Storage t (number of bytes) required for one line.

The storage capacity C is determined by the number of bytes required to store one display data item in the screen memory 5b that stores display data on the display 6 described above. That is, as display data, a character code such as an EBCDIC code and an underline are used to generate one character pattern.

A predetermined number of bytes are preset to store display modes such as blanking.
It is determined by C, and the relationship L=CX (number of characters displayed on one line) holds true.

The operation of the data processing apparatus shown in the embodiment will be explained below according to the flowchart shown in FIG.

First, when the operator inputs power to the device, or inputs a command to start the device using a predetermined key on the keyboard 4, the CPU 2 performs a screen setting operation. Let's do it. a
First, the CPU 2 initializes the cursor position [t address] in the cursor position register 5a provided in the display interface 5.

The display interface 5 displays a display area on the display 6 corresponding to the set cursor position address, for example, an area 6'17m cursor area. The screen cent is completed by the cursor display (7), and then the CPU 2 performs a memory address setting operation.

Normally, the processing modes input from the keyboard 4 include a 1-key mode specified by pressing a single key such as deleting one character at cursor line feed, and a function mode specified by a combination of 棧朕 characters. It is also necessary to store the character code sound 1 corresponding to the character displayed by the Vc light on the display 6 in the code store area 7e. Therefore, a memory address corresponding to the initialized cursor display position, such as the address AOi address register 7d, is set to display value +1ftk, and the memory address setting operation is completed.

Furthermore, CPU2 moves to the next sequence and enters the cursor movement mode? To set the normal mode, set DCP=IC MCP=IC. The above operations complete the starting operation of the data processing device, and the data processing device enters a state of accepting key-in data from the operator.

When a key on the keyboard 4 is pressed by the operator, the display bit (for example, bit 3a11) of the key-in display register 3a provided in the keyboard interface 3 is set. In other words, this display bit 3a' indicates which key on the keyboard 4 is pressed. The CPU 2, which is set by hardware even when pressed, determines that data has been input from the keyboard 4 by detecting the sound that this display bit 3a' is set. The method is to set CPU2 to always display bit 3a.
Possible methods include a method of checking f or an interrupt signal format from the keyboard interface 3. When it is detected that the above-mentioned display bit 3a' is set by the operator's kill-in operation, the CPU 2 displays the value of the food register 3b in which the key code corresponding to the pressed key is stored. Furthermore, in order to detect the next key-in operation, the display beep) 3a' f is reset.

Is the read key code of CPU2 the processing mode? It is determined whether the data is specified data or a character code that is display data, and the process proceeds to predetermined processing operations. Note that the flowchart only shows the processing operations of the CPU 2 according to the present invention, and other processing operations are omitted. In other words, the CPU 2 when the cursor movement mode is specified and when display data is specified.
The processing operation will be described below.

When the cursor movement mode is specified, the CPU 2 uses the mode register 7a in the memory 7 mentioned above.
The specified movement mode is determined by checking the status of the 2-bit data, and the values of the screen count-up register DCP and the memory count-up register MCP are set in accordance with each movement mode as shown in the flowchart. Furthermore, the movement mode set by CPU2? By displaying it in a mode display area (not shown) on the display 6, the operator can confirm that the specified movement mode has been set. When this mode display sequence is completed, the CPU 2 returns to the data input sequence by the next key-in operation.

The processing operation when the key-in key code is display data is described below.0 The CPU 2 is the key-in display data display 6.
It is displayed on the top and stored in the code store area 7e in the memory 7. That is, the CPU 2 stores the cursor position indicated by the cursor position register 5a in the display data interface 5. This allows the display interface 5 to display a screen memo! j5by-pattern corresponding to stored display data? Display at the display location where the cursor is displayed on the display. The CPU 2 also stores this display data (key code) in the code store area 7@[of the memory 7, and stores it at the address indicated by the address register 7dfC. Store.

When the keyed-in display data has been displayed and stored in the memory, the CPU 2 updates the cursor and the storage address of the memory 7 in preparation for inputting the next display data. That is, the value of the screen count up register (DCP register) 7b is stored in the cursor position register 5a? By adding
The next cursor position to be displayed is determined. Furthermore, address register 7d [memory count up register (M
By adding the values in the CP register 17c, the next storage address in the memory 7 is determined. When the values of the cursor position register 5a and the address register 7d are updated, the CPU moves the cursor entirely to the display location on the display corresponding to the address value indicated in the cursor position register 5a.

When the above operations are completed, the CPU 2 returns to the sequence of waiting for a key-in operation, and thereafter, each time a key-in is performed, it is determined whether the input data is a processing mode or display data, and the same processing is performed in each case.

In this way, in this embodiment, the processing mode specified by the key-in operation is the cursor movement mode? Please set L mode, U
Since the cursor movement amount and memory address movement amount corresponding to each mode are set for the DcP counter and MCP counter, the cursor movement on the display can be set freely. For example, by pressing a finger in U mode, display data will be input by the next key-in operation, and when the character corresponding to the display data is displayed at the current cursor display position on the display, the cursor will automatically move down. do.

Therefore, when creating vertically written text, the operator only needs to input character keys continuously, instead of using conventional cursor movement keys. The cursor set action you used is completely incorrect! 〇〇Effects of the Invention As detailed above, according to the present invention, the cursor movement after key-in can be set in advance, and the character 9 figure can be moved in a desired direction. You can input display patterns such as

Therefore, for example, when inputting a single figure of vertically written text, or when inputting letter sounds sequentially from left to right, there is no need to manually set the cursor position each time as in the past, which makes the operation more troublesome. Is it possible to erase a large amount of data and also have free display formats for text, figures, etc.? Specify faster.

It can be provided to the data processing device f' that can create the data.
