Description

TECHNICAL FIELD OF THE INVENTION The present invention relates to a human key input device using a display, and more particularly, before input data is finally inputted, it is stored in a human key input buffer storage means, and the contents are stored on a display. The present invention relates to an improvement of means for correcting errors in input data in a key input device configured to display a key.

Prior Art and Problems In a numerical control device equipped with a CRT display, in order to give the operator room to check and change the data input manually using the keys, the data entered from the keyboard is temporarily stored in a buffer for manual input using the keys. is divided into a main display area and a key buffer display area, and is displayed in the key buffer display area of the CRT display screen. In this case, conventionally, only one cursor was displayed in the main display area, and the input data was stored sequentially from the beginning of the key manual buffer. After specifying the position of the main display area to perform operations such as changes and additions, and pressing the key manual execution key after inputting the necessary data, the final key manual operation, that is, the change of the specified location, is performed.

Processing such as addition is executed.

By the way, as anyone who has experienced the above-mentioned manual key operations will understand, errors in input data are often made due to incorrect keystrokes. In such a case, conventionally, a separately provided cancel key was pressed to cancel all input data up to that point. However, this requires redoing the key manually from the beginning, which is troublesome.

Purpose of the Invention The present invention has been made in view of these circumstances.
The purpose is to provide, in addition to the cursor for the main display area, a cursor that indicates the position of the key operated by that key when the data input key is pressed, and to make this cursor movable. By doing so, it is possible to easily and quickly correct erroneously input data.

Composition of the invention FIG. 1 is an explanatory diagram of the configuration of the present invention.

The data input using the data input key ○K of the keyboard KB is temporarily stored in the key manual buffer storage means BUF, and its contents are displayed in the key manual buffer display area KDPY of the display DPY. The screen of the display device DPY is divided into a key manual buffer display area [IPY and a main display area MDPY, and a main cursor MC3L and a sub-cursor 5C3L are displayed in each area. Main cursor control means C3
The LCr displays the main cursor MC3L at a position that is operated according to the contents of the key manual buffer storage means BtlF, and also moves the main cursor MC5L up and down in accordance with the operation of the cursor movement key CMK, which is made up of two pairs of movement keys on the keyboard KB. a first control mode for moving left and right;
It has a second control mode in which the main cursor MC3L is moved in the left-right direction in accordance with the operation of a pair of predetermined movement keys SH.

The secondary cursor control means C3LC2 displays the secondary cursor 5C3L at the position of the key manual buffer storage means BIJF into which data input from the keyboard KB is written, and controls the operation of a predetermined pair of movement keys on the keyboard KB. The sub cursor 5cst is moved in the left/right direction accordingly. The key manual buffer control means KCNT writes the data inputted from the keyboard KB to the storage location of the key manual buffer storage means BUF instructed by the secondary cursor control means C3LC2, and the main cursor control means C
3LC, and the sub-cursor control means C3LC2, their operations are controlled by the selection means 5LCT depending on the presence or absence of data in the key manual buffer storage means BUF and the pressed state of the cursor switching key CCNGH. That is, when there is no data in the key manual buffer storage means BUF, or when there is data but the cursor switching key CCNGH is used to use the main cursor only, the operation of the sub-cursor control means C5LC2 is prohibited, and the key manual manual operation is prohibited. When there is data in the buffer storage means BUF and a predetermined pair of movement keys are dedicated to the sub cursor 5CSL by the cursor switching key CCNGK, the operation of the sub cursor control means C5LC2 is enabled. At the same time, the main cursor control means C3LC is switched to the second control mode. The key human power control means INPC controls the main display area MDPY by the data stored in the key human power buffer storage means BtlF when the key human power execution key INPT is pressed.
This is to change the part indicated by the main cursor MC5L displayed on the screen.

FIG. 5 is a flowchart showing an example of the software configuration of the overall processing of the cursor control function in the embodiment of the present invention.

The microprocessor 1 determines whether the key input from the keyboard 20 is a cursor movement key (Sl), and if it is a cursor movement key, if the key input buffer area 7a is empty, controls the movement of the main cursor 32.32. 33)
, if data has been input, a pair of movement keys 41.42
It is determined whether or not has been pressed (S4). As a result of this determination, if the movement keys 41 and 42 are pressed, the main cursor 3
If the movement keys 43 and 44 are pressed, the movement control of the main cursor 32 is executed when the cursor switching key 46 is on and not for secondary cursor control, and the cursor switching key 46 is pressed. is off and used for secondary cursor control, executes movement control of the secondary cursor 33 (S
5, 5fi). That is, once data input is started from the keyboard 20, the pair of movement keys 43 and 44 are used exclusively for the secondary cursor 33, and otherwise they are used only for the main cursor 32.
It is for exclusive use. Further, even during data input, when the cursor switching key 46 is turned on, all the movement keys 41 to 44 are used exclusively for the main cursor 32. When a key other than the cursor movement key is pressed, other processing matching the pressed key is executed (S7). for example,
When a data input key such as a number or alphabet is pressed, the key code is stored in the storage position of the key input bar area 7a indicated by the sub-cursor 33, and when an input key is pressed, the key code is stored in the memory position of the key input bar area 7a, which is indicated by the sub-cursor 33. executes decoding of the contents stored in the key manual buffer area 7a, writes data to a predetermined location, and clears the contents of the key manual buffer area 7a after the writing is completed.

Figures 6 to 11 show the main cursor 32 and the secondary cursor 33.
3 is a flowchart illustrating an example of a software configuration for realizing a movement control function.

(See FIG. 6) When the movement key 44 is pressed, the microprocessor 1 first determines whether the contents of the key manual buffer area 7a are empty (3B), and if it is empty, controls the movement of the main cursor 32. and if data is stored, press cursor switch key 4.
When the cursor 6 is on, the movement of the main cursor 32 is controlled, and when it is off, the process moves to step S50 in FIG. 10 to control the sub-cursor 33 (S10). Next, the microprocessor 1 determines the current value of the main cursor 32, and if it is not the last row of the main display area 30, moves the main cursor 32 to the ninth row of the current column (39. 311). Further, if it is the last row, the main cursor 32 is moved to the first row and first column of the next page if it is the last column, and if it is not the last column, it is moved to the next column and first row (812-514). The current value of the main cursor 32 is determined by reading the contents of the cursor register 8 and comparing it with a reference value, and the main cursor 32 is moved by changing the contents of the cursor register 8.

(See FIG. 7) When the movement key 43 is pressed, the microprocessor 1 first determines whether the contents of the key manual buffer area 7a are empty (520), and if it is empty, controls the movement of the main cursor 32. If the cursor switching key 46 is on, the movement of the main cursor n is controlled.
When it is off, the process moves to step 360 in FIG. 11 to control the secondary cursor 33 (S22). Next, the microprocessor 1 determines the current value of the main cursor 32, and if it is not the first row of the main display area 30, moves the main cursor 32 to the current column and the previous row (321, 323). Further, if it is the first row, the main cursor 32 is moved to the last row and last column of the previous page if it is the first column, and if it is not the first column, it is moved to the previous column and last row (824-526).

(See FIG. 8) When the movement key 41 is pressed, the microprocessor 1 determines the current value of the main cursor feather, and if it is not the last column of the main display area 30, the main cursor 32 is moved to the current value.

Move to the next column (330.331). Also, if it is the last column, move the main cursor 32 to the first row and first column of the next page if it is the last row, and if it is not the last row, move the main cursor 32 to the next line.

It is moved to the first column (832-534).

(See FIG. 9) When the movement key 42 is pressed, the microprocessor 1 determines the current value of the main cursor 32 and moves the main cursor 32 to the current value if it is not in the first column of the main display area 30.

It is moved to the front row (S40.541). Also, if it is the first column, move the main cursor 32 to the last row and last column of the previous page if it is the first row, and if it is not the first row, move the main cursor 32 to the previous row.

It is moved to the last column (S42-544).

(See FIG. 10) When the key manual buffer area 7a is not empty and the movement key 44 is pressed while the cursor switching key 46 is off, the microprocessor 1 first determines the current value of the sub cursor 33. , moves the secondary cursor 33 to the current primary column if it is not the last column of the key manual buffer display area 31 (
350.351). Also, if it is the last column or the last row, move the secondary cursor 33 to the first row.

It is moved to the first column, and if it is not found in the last row, it is moved to the next row and first column (S52 to SS+). In addition, the secondary cursor 33
The main cursor 32 is used to determine the current value of and move the secondary cursor.
It can be done similarly.

(See FIG. 11) When the key manual buffer area 7a is not empty and the movement key 42 is pressed while the cursor switching key 46 is off, the microprocessor determines the current value of the sub-cursor 33, If the key is not in the first column of the manual buffer display area 31, move the secondary cursor 33 to the current position.

Move to the front row (361), 5GI). Also, if it is the first column □, if it is the first row, move the secondary cursor 33 to the last row,
It is moved to the last column, and if it is not the first row, it is moved to the previous row and last column (S62 to 864).

Note that the main cursor 32. In the initial state, the secondary cursor 33 is, for example, located in the main display area 30. The key is assumed to be located in the first row and first column of the manual buffer display area 31, and the sub-cursor 33 moves one step to the right every time one data is input to indicate the next input position. Further, the cursor switching key 46 is set to the OFF state when the key operation is started, and when the key 46 is pressed once, it becomes the ON state, and when pressed again, the cursor switching key 46 is set to the OFF state.Such processing is executed by a program. (Also, it is also possible to provide a configuration in which a flip-flop repeats the inversion operation based on the output of the cursor switching key 46.Furthermore, a pair of movement keys 43 and 44 are currently used for controlling the main cursor 32 or for controlling the sub-cursor 33. It is preferable to display the information at an appropriate location on the screen.

Since this embodiment has such a configuration, for example, the editing content is called up in the main display area 30 and the cursor is moved -v
--40, point out the insertion point using the main cursor 32, and enter characters from the keyboard.
Input data is sequentially stored in the key human power buffer area 7a and displayed in the key human power buffer display area 31. If you enter incorrect data, operate the pair of movement keys 43 and 44 of the cursor movement key 40 to move the sub-cursor 33 to the relevant location, and input the correct data manually. The corresponding part of the buffer area 7a is rewritten and the correct contents are displayed.

In addition, if you want to change the edited part while manually editing the data key,
The main cursor 32 may be moved in the horizontal direction by operating a pair of movement keys 41 and 42. Also, if you want to change the editing part in the vertical direction of the screen, you can also use the movement keys 41 and 42, but it is better to press the cursor switch key 46 and use the movement keys 43 and 44 exclusively for the main cursor 32. is efficient. Thereafter, when the input key 6 of the keyboard 20 is pressed, the contents of the manual keypad area 7a are inserted into the corresponding location of the main display area in the above example. Note that in the above embodiments, a CRT display was used as the display, but a liquid crystal display, a plasma display, etc. may also be used. In addition, a pair of movement keys for moving the secondary cursor 33 are used as movement keys 41 and 42.
Other combinations such as the movement keys 41 and 44 may also be used.

As described in detail, in the present invention, a cursor is also provided in the key person cover sofa display area 31, and this can be moved by operating a pair of movement keys in the cursor movement key 40 while the key is being manually operated. It becomes possible to partially change the data in the key manual buffer area 7a, which was previously impossible, and the operability is greatly improved.

Further, in the present invention, the sub cursor 32 is moved by using a part of the cursor movement keys 40 that move the main cursor 32 in the main display area.
Since the keyboard is configured to move 3, the keyboard can be made smaller and less expensive compared to a configuration in which separate cursor movement keys are provided for both cursors. Furthermore, since the main cursor 32 can be moved left and right even when the data key is manually operated, it is possible to change the editing location, etc. Also, by using the cursor switching key, it is possible to move all movement keys as the main cursor when the data key is manually operated. Since the cursor 32 can be returned to moving, the operability is further improved.
