TECHNICAL FIELD The present invention relates to an improvement of a data processing device for inputting data via a field displayed on a display screen.

(Prior Art) Conventionally, in a data processing device such as a terminal device in an information system of a financial institution, a plurality of data input fields are displayed on a display screen, and a cursor indicating a data input position on the display screen is displayed. According to the operation of the keyboard, the data is input by moving it to any position of the plurality of fields.

FIG. 2 shows an example of a conventional data processing apparatus of this type. In the figure, 1 is a keyboard provided with a tab key 2 for instructing cursor movement to the next field, 3 is a keyboard controller, 4 is a display, 5 is a display controller, 6 is a memory, 7 is a floppy disk drive, 8 is a floppy disk drive (FDD) controller, 9 is a printer, 10 is a printer controller,
11 is a communication line, 12 is a line interface, and 13 is a central processing unit (CPU).

FIG. 3 shows an example of a display screen in the above apparatus. In the figure, 21-1, 21-2, 21-3, 21-4, 21-5 are data input fields, 22-1, 22. -2-, 22-3,22-4,22-
Reference numeral 5 is an item indicating the contents of each field 21-1 to 21-5 (however, only the item number is shown in the illustrated example), and 23 is a cursor indicating the data input position. Each field 21-
1 to 21-5 are left delimiters 2 indicated by "[" in the figure
4. It consists of the right delimiter 25 indicated by "]" and the space (blank) sandwiched between them.

FIG. 4 shows a table 30 showing the attributes of each field on the display screen described above. The total number N of fields on the screen (N = 5 in the example of FIG. 3), No. 1 field 21-
Relative address SA1 of the left delimiter corresponding to 1 (field address in the column direction) and field digit number (the number of spaces between the left and right delimiters) m1 and relative address SA2 of the left delimiter corresponding to field 21-2 of No. 2 Number of digits m
2. It consists of the relative address SA5 of the left delimiter corresponding to field 21-5 of No. 5 and the number of field digits m5. The table 30 is stored in the memory 6 together with data corresponding to the contents of the display screen.

FIG. 5 shows the flow of a program relating to the operation of the tab key in the above apparatus, and the operation of moving the cursor between fields will be described below.

First, when the operator depresses the tab key 2 of the keyboard 1, the keyboard controller 3 detects this and sends the tab key input information to the CPU 13 by interrupt processing. CPU13
Detects this (step s1), the field number n0 at which the cursor 23 exists (n0 in the example of FIG. 3)
= 1) is not equal to the total number N of fields, that is, whether or not the cursor 23 is in the last field on the screen (step s2). If n0 = N, add "1" to the number n0 ( Step s3), number n0 after addition (in the example of FIG. 3,
Data of the field corresponding to n0 = 2) is read from the table 30 (step s4), and the cursor set address KA indicating the position where the cursor 23 is displayed is calculated (step s).
Five). Here, assuming that the display position of the cursor 23 is on the left side of the right delimiter in the field, the data read from the table 30, that is, the relative address and the number of field digits of the left delimiter (SA2 and m2 in the example of FIG. 3) are set. Simply add.

The CPU 13 sends a cursor set command to the display controller 5 together with the calculated cursor set address KA (step s6). The display controller 5 controls the display 4 to display the cursor 23 at the address KA on the display screen. FIG. 6 shows a display screen when the tab key 2 is operated once in the display screen shown in FIG.

In the above process, when n0 = N, the CPU 13 determines the number n.
The value of 0 is changed to "1", that is, the number of the head field (step s7), and the processes of steps s4 to s6 described above are performed.

The above-mentioned movement of the cursor 23 to the next field is carried out every time the tab key 2 is pressed, and if the data is input from the keyboard 1 while the cursor 23 is displayed on the field where the data is to be input, the actual data input Is executed.

(Problems to be Solved by the Invention) However, in the above device, the cursor 23 always moves only one field with respect to one pressing of the tab key 2, so that one field requiring data input and another field need to be input. Even if there are a large number of fields that do not require data input in between, the tab key must be pressed down a number of times corresponding to the number of fields, which causes the operator to waste time and effort.

It is an object of the present invention to eliminate the above-mentioned problems and provide a data processing device which can efficiently input data.

(Means for Solving the Problems) In order to achieve the above object, the present invention provides a cursor for indicating a data input position on a display screen of a display for inputting a plurality of data displayed on the display screen based on a keyboard operation.

And a second key information is generated by detecting the depression of the second key. Second key input detection means, first search means for searching the next field from the data storage means when the first key information occurs, and the data storage means when the second key information occurs Second search means for searching the next specific field by the control code of the specific field data, and a cursor to be displayed on the display screen based on the search result of the first search means or the second search means. A data processing device provided with a cursor position designating means for designating a position and a cursor display means for displaying a cursor at a designated position on a display screen of a display is proposed.

(Operation) According to the present invention, by storing the data corresponding to the content of the display screen in which the control code is added to the specific field in advance in the data storage means, the first key is pressed and the first key is pressed. The key information of 1 is generated, the first search means is activated by this, the next field is searched from the data storage means, and the searched next field is specified at the cursor position by the cursor position specifying means. The cursor display means displays the cursor in the next field on the screen of the display, and the second key information is generated based on the depression of the second key, which activates the second search means and the data. The next specific field is searched from the storage means, and the searched next specific field is specified at the cursor position by the cursor position specifying means; Cursor to the next specific field on the display screen is displayed by the cursor display means al.

7 is a floppy disk drive, 8 is a floppy disk drive (FDD) controller, 9 is a printer, 10
Is a printer controller, 11 is a communication line, 12 is a line interface, 13a is a central processing unit, and 14 is a skip key.

The keyboard 1a is the same as the conventional keyboard 1 except that a skip key 14 for instructing the cursor movement to the next specific field is provided, and corresponds to the keyboard a in FIG.

The keyboard controller 3a is the same as the conventional keyboard controller 3 except that it detects the pressing of the skip key 14 and generates its information, and it has the first key input detecting means b and the second key input detecting means b in FIG. The key input detection means c is included.

The display 4 corresponds to the display i in FIG. 1, and the display controller 5 includes the cursor display means h in FIG.

The memory 6a stores the above-mentioned field attribute table, a predetermined program, and the like, together with data corresponding to the contents of the display screen including a control code for designating a specific field among a plurality of fields. It includes a storage means d.

The CPU 13a controls each circuit in accordance with a predetermined program. The program includes not only the conventional programs including the program related to the operation of the tab key 2 described above but also the program related to the operation of the skip key 14. There is.

FIG. 8 shows an example of a display screen in the device of the present invention. In the figure, 21-1 to 21-5 are fields and 22-1 to 22-1.
22-5 is an item indicating the contents of each field 21-1 to 21-5, 23 is a cursor, 24 is a left delimiter, 25 is a right delimiter, and 26 is a control code. The control code 26 is added in advance just before a specific field (21-5 in the illustrated example) in which data is frequently input among a plurality of fields (that is, immediately before the left delimiter 24). The control code 26
Is added only on the data stored in the memory 6a and is not actually displayed on the display screen,
It is shown here for easy understanding. Further, although only one control code 26 is added in the illustrated example, any number can be added to any field.

FIG. 9 shows the flow of a program relating to the operation of the skip key 14. The operation of moving the cursor to a specific field will be described below.

First, when the operator pushes down the skip key 14 of the keyboard 1a, the keyboard controller 3a detects this and sends the skip key input information to the CPU 13a by interrupt processing.

The CPU 13a detects the skip key input information (step
sp1) and the field number n0 (n0 = 1 in the example of FIG. 8) of the field where the cursor 23 exists at that time are the total number N of fields.
, That is, whether the cursor 23 is in the last field on the screen (step sp2).

If n0 = N is not satisfied, the CPU 13a substitutes the number n0 for the number n indicating the field for checking the presence or absence of the control code (step
sp3), and add "1" to the number n (step sp
4) Read the relative address (SA2 in the example of FIG. 8) of the left delimiter of the field corresponding to the number n (n = 2 in the example of FIG. 8) after addition from the table 30 (step s
p5), the address of the position where the control code 26 is added by subtracting "1" from the relative address of the left delimiter
Calculate IA (step sp6). Furthermore, the CPU 13a has a memory 6
The data corresponding to the address IA is read from the data corresponding to the display screen stored in a (step sp7), and it is checked whether or not this is the control code 26 (step sp).
8).

Here, the data corresponding to the address IA is the control code 26.
If not, the CPU 13a checks whether the number n at this point is not equal to the total number N of fields, that is, whether there is a field to be checked (step sp9), and n = N.
If not, the processes of steps sp4 to sp8 are repeated.

On the other hand, if the data corresponding to the address IA is the control code 26, the CPU 13a indicates the field number where the cursor 23 is located.
Substitute the number n at that time into n0 (step sp1
0), the data of the field corresponding to the number n0 at this time (n0 = 5 in the example of FIG. 8) is read from the table 30 (step sp11), and the cursor set address KA is set in the same manner as in the tab key processing described above. Calculate (step sp12),
A cursor set command is sent to the display controller 5 together with the cursor set address KA (step sp13).

The display controller 5 controls the display 4 to display the cursor 23 at the address KA on the display screen. FIG. 10 shows the display screen shown in FIG.
The display screen when the skip key 14 is operated once is shown.

In the above process, when n0 = N, CPU13a
n0 is changed to "1", that is, the number of the first field (step sp14), and the above-described processing of steps sp11 to sp13 is performed, and when n = N, that is, from the field where the cursor is displayed at that time. When there is no control code in the lower field, the CPU 13a adds "1" to the number n0, that is, 1
The number of the field immediately below is changed (step sp15), and the processes of steps sp11 to sp13 described above are performed.

The above-mentioned movement of the cursor 23 to the next specific field is performed each time the skip key 14 is pressed, and if the data is input from the keyboard 1a while the cursor 23 is displayed on the field to input the data, the actual Data entry is performed. When the tab key 2 is depressed, the cursor 23 is moved to the next field as in the case of the conventional example. Therefore, if the operations of the skip key 14 and the tab key 2 are properly combined, the cursor 23 can be moved quickly and data can be input very efficiently.

In the above embodiment, when the tab key 2 or the skip key 14 is pressed while the cursor 23 is in the last field, the first field is restored, but it may be displayed in the last field as it is.
Further, when the next screen exists, the screen may be switched.

In addition, the control code described above is used immediately before the data relating to the corresponding field in the program when creating the data that constitutes the display screen, that is, when programming the screen image data in the screen generator language based on the created screen image. Is added by inserting a specific code into. A control code can be newly added to or deleted from the screen image data already programmed, and the field itself can be added or deleted.

As described above, according to the present invention, by adding a control code to a specific field in the screen data in advance, for example, a field that frequently requires data input, You can move the cursor to the next field based on a key press and also move the cursor to the next specific field based on a second key press, thus moving the cursor to the field that requires data entry. It has advantages that it can be moved quickly and that data can be input quickly.
